前言

　　　本文以分油套为对象，详细介绍其注射模设计过程。设计中主要用PRO/ENGINEER软件，根据制件的零件图进行零件的三维造型，采用模具专家系统EMX，提高了设计效率。通过Autocad完成工程图的制作，从塑料材料的性能分析，根据塑件的基本形状和尺寸入手，合理选择注射的成型方法。根据注塑的额定注塑量我们可以确定模具的型腔为一模一腔，制件圆周方向有12个侧孔，无法直接脱模，所以我们需要设计侧抽芯机构，利用转盘带动滑块来同时完成12个侧孔的抽芯，最后当主流道余料全部被拉出后，再利用推杆推出机构完成塑件的推出。

　　　需要分析的问题是：塑料在型腔内的注射过程中流动情况，温度压力变化情况、注塑件残余应力等, 根据分析检查模具结构、流动状态、产品质量等问题。如是否存在浇注系统不合理, 流道和浇口位置尺寸是否不当, 型腔平衡以及产品的翘曲变形等。设计完成后，最后通过Autocad完成工程图的制作。

　　1塑料制品和注射成形在模具业的重要地位

　　　塑料制品具有原料来源丰富,价格低廉,性能优良等特点。它在电脑、手机、汽车、电子、汽车、电机、电器、仪器仪表、家电和通讯产品制造中具有不可替代的作用，应用极其广泛。

　　　注射成形是成形热塑件的主要方法，因此应用范围很广。注射成形是把塑料原料放入料筒中经过加热熔化，使之成为高黏度的流体，用柱塞或螺杆作为加压工具，使熔体通过喷嘴以较高压力注入模具的型腔中，经过冷却、凝固阶段，而后从模具中脱出，成为塑料制品。

　　　塑料注射成形工艺的最大特点是复制，能够复制出所需任意数量的可直接使用或稍作处理即可使用的制品，是一种适宜大批量生产的工艺。虽然在设备上投入较大，但是可以生产制品的数量非常大，实属一种经济快捷的生产方式，因此得到广泛的应用和快速的发展。

　　2模具在我国的发展历程

　　　过去在我国工业中，模具长期未受到重视。改革开放以来，塑料成形、家用电器、仪表、汽车等行业进入大批量生产，模具工业有了一定的发展。随着现代工业发展的需要，塑料制品在工业、农业和日常生活等各个领域的应用越来越广泛，质量要求也越来越高。当今社会的进步和发展，使原有的商品已经不能满足人们对物质的需求，然而有些商品的制造必须依靠模具才能够生产加工出来，因此，模具的发展与人们的生活关系越来越紧密，如我们使用的电脑、手机、汽车等产品都要依靠模具。在塑料制品的生产中，高质量的模具设计、先进的模具制造设备、合理的加工工艺、优质的模具材料和现代化的成形设备等都是成形优质塑件的重要条件。

　　　我国模具工业虽然有了长足的发展，取得了巨大进步，但是我们也要清醒地看到，我国模具工业总体水平比工业发达国家要落后很多，这与我国制造业发展的要求相比差距还很大；我们的企业技术装备还比较落后，劳动生产率也较低；模具生产专业化、商品化、标准化程度也不够高；模具产品主要还是以中低档为主，技术含量较低，高中档模具多数要依靠进口，产品结构调整的任务很重；人才紧缺，管理滞后的状况依然突出，等等。可见，我国模具工业的发展任重而道远。

　　3前景展望

　　　我国进入实施国民经济和社会发展的第十一个五年规划期，模具工业的发展也将进入一个关键时期。在这一时期，模具行业的主要任务是，在党中央关于把我国建设成为创新型国家的战略思想指引下，进一步推进改革，调整结构，开拓市场，苦练内功，提升水平，使我国模具工业在整体上再上一个新台阶。不断提升模具制造水平，振兴我国装备制造业，为实现把我国建设成为制造业强国的宏伟目标而奋斗。

我国进入实施国民经济和社会发展的第十一个五年规划期，模具工业的发展也将进入一个关键时期。在这一时期，模具行业的主要任务是，

内容简介：: Die history1 Die position in industrial productionMold is a high-volume products with the shape tool, is the main process of industrial production equipment. With mold components, with high efficiency, good quality, low cost, saving energy and raw materials and a series of advantages, with the mold workpieces possess high accuracy, high complexity, high consistency, high productivity and low consumption , other manufacturing methods can not match.Have already become an important means of industrial production and technological development.The basis of the modern industrial economy. 现代工业品的发展和技术水平的提高，很大程度上取决于模具工业的发展水平，因此模具工业对国民经济和社会发展将起越来越大的作用。The development of modern industrial and technological level depends largely on the level of industrial development die,so die industry to national economic and social development will play an increasing role.March 1989 the State Council promulgated on the current industrial policy decision points in the mold as the machinery industry transformation sequence of the first, production and capital construction of the second sequence (after the large-scale power generation equipment and the corresponding power transmission equipment), establish tooling industry in an important position in the national economy. 1997 年以来，又相继把模具及其加工技术和设备列入了当前国家重点鼓励发展的产业、产品和技术目录和鼓励外商投资产业目录。 Since 1997, they have to mold and its processing technology and equipment included in the current national focus on encouraging the development of industries, products and technologies catalog and to encourage foreign investment industry directory. 经国务院批准，从 1997 年到 2000 年，对 80 多家国有专业模具厂实行增值税返还 70% 的优惠政策，以扶植模具工业的发展。 Approved by the State Council, from 1997 to 2000, more than 80 professional mold factory owned 70% VAT refund of preferential policies to support mold industry. 所有这些，都充分体现了国务院和国家有关部门对发展模具工业的重视和支持。 All these have fully demonstrated the development of the State Council and state departments tooling industry attention and support. 目前全世界模具年产值约为 600 亿美元，日、美等工业发达国家的模具工业产值已超过机床工业，从 1997 年开始，我国模具工业产值也超过了机床工业产值。 Mold around the world about the current annual output of 60 billion U.S. dollars, Japan, the United States and other industrialized countries die of industrial output value of more than machine tool industry, beginning in 1997, Chinas industrial output value has exceeded the mold machine tool industry output.据统计，在家电、玩具等轻工行业，近 90 的零件是综筷具生产的；在飞机、汽车、农机和无线电行业，这个比例也超过 60 。 According to statistics, home appliances, toys and other light industries, nearly 90% of the parts are integrated with production of chopsticks; in aircraft, automobiles, agricultural machinery and radio industries, the proportion exceeded 60%. 例如飞机制造业，某型战斗机模具使用量超过三万套，其中主机八千套、发动机二千套、辅机二万套。 Such as aircraft manufacturing, the use of a certain type of fighter dies more than 30,000 units, of which the host 8000 sets, 2000 sets of engines, auxiliary 20 000 sets. 从产值看， 80 年代以来，美、日等工业发达国家模具行业的产值已超过机床行业，并又有继续增长的趋势。 From the output of view, since the 80s, the United States, Japan and other industrialized countries die industry output value has exceeded the machine tool industry, and there are still rising. 据国际生产技术协会预测，到 2000 年，产品尽件粗加工的 75% 、精加工的 50 将由模具完成；金属、塑料、陶瓷、橡胶、建材等工业制品大部分将由模具完成， 50 以上的金属板材、 80 以上的塑料都特通过模具转化成制品。 Production technology, according to the International Association predicts that in 2000, the product best pieces of rough 75%, 50% will be finished mold completed; metals, plastics, ceramics, rubber, building materials and other industrial products, most of the mold will be completed in more than 50% metal plates, more than 80% of all plastic products, especially through the mold into.模具的历史发展 2 The historical development of mold模具的出现可以追溯到几千年前的陶器和青铜器铸造，但其大规模使用却是随着现代工业的掘起而发展起来的。 The emergence of mold can be traced back thousands of years ago, pottery and bronze foundry, but the large-scale use is with the rise of modern industry and developed.19 世纪，随着军火工业 ( 枪炮的弹壳 ) 、钟表工业、无线电工业的发展，冲模得到广泛使用。 The 19th century, with the arms industry (guns shell), watch industry, radio industry, dies are widely used. After World War II, with the rapid development of world economy, it became a mass production of household appliances, automobiles, electronic equipment, cameras, watches and other parts the best way. 从世界范围看，当时美国的冲压技术走在前列许多模具先进技术，如简易模具、高效率模具、高寿命模具和冲压自动化技术，大多起源于美国；而瑞士的精冲、德国的冷挤压技术，苏联对塑性加工的研究也处于世界先进行列。 From a global perspective, when the United States in the forefront of stamping technology - many die of advanced technologies, such as simple mold, high efficiency, mold, die and stamping the high life automation, mostly originated in the United States; and Switzerland, fine blanking, cold in Germany extrusion technology, plastic processing of the Soviet Union are at the world advanced. 50s, mold industry focus is based on subscriber demand, production can meet the product requirements of the mold. Multi-die design rule of thumb, reference has been drawing and perceptual knowledge, on the design of mold parts of a lack of real understanding of function. From 1955 to 1965, is the pressure processing of exploration and development of the times - the main components of the mold and the stress state of the function of a mathematical sub-bridge, and to continue to apply to on-site practical knowledge to make stamping technology in all aspects of a leap in development.The result is summarized mold design principles, and makes the pressure machine, stamping materials, processing methods, plum with a structure, mold materials, mold manufacturing method, the field of automation devices, a new look to the practical direction of advance, so that pressing processing apparatus capable of producing quality products from the first stage.Into the 70s to high speed, launch technology, precision, security, development of the second stage.Continue to emerge in this process a variety of high efficiency, business life, high-precision multi-functional automatic school to help with.Represented by the number of working places as much as other progressive die and dozens of multi-station transfer station module.On this basis, has developed both a continuous pressing station there are more slide forming station of the press - bending machine.In the meantime, the Japanese stand to the worlds largest - the mold into the micron-level precision, die life, alloy tool steel mold has reached tens of millions of times, carbide steel mold to each of hundreds of millions of times p minutes for stamping the number of small presses usually 200 to 300, up to 1200 times to 1500 times.In the meantime, in order to meet product updates quickly, with the short duration (such as cars modified, refurbished toys, etc.) need a variety of economic-type mold, such as zinc alloy die down, polyurethane rubber mold, die steel skin, also has been very great development.从 70 年代中期至今可以说是计算机辅助设计、辅助制造技术不断发展的时代。 From the mid-70s so far can be said that computer-aided design, supporting the continuous development of manufacturing technology of the times.With the precision and complexity of mold rising, accelerating the production cycle, the mold industry, the quality of equipment and personnel are required to improve.Rely on common processing equipment, their experience and skills can not meet the needs of mold.Since the 90s, mechanical and electronic technologies in close connection with the development of NC machine tools, such as CNC wire cutting machine, CNC EDM, CNC milling, CNC coordinate grinding machine and so on.The use of computer automatic programming, control CNC machine tools to improve the efficiency in the use and scope.In recent years, has developed a computer to time-sharing by the way a group of direct management and control of CNC machine tools NNC system.随着计算机技术的发展，计算机也逐步进入模具生产的各个领域，包括设计、制造、管理等。 With the development of computer technology, computers have gradually into the mold in all areas, including design, manufacturing and management.International Association for the Study of production forecasts to 2000, as a means of links between design and manufacturing drawings will lose its primary role.Automatic Design of die most fundamental point is to establish the mold standard and design standards.To get rid of the people of the past, and practical experience to judge the composition of the design center, we must take past experiences and ways of thinking, for series, numerical value, the number of type-based, as the design criteria to the computer store.Components are dry because of mold constitutes a million other differences, to come up with a can adapt to various parts of the design software almost impossible. But some products do not change the shape of parts, mold structure has certain rules, can be summed up for the automatic design of software.If a Japanese companys CDM system for progressive die design and manufacturing, including the importation of parts of the figure, rough start, strip layout, determine the size and standard templates, assembly drawing and parts, the output NC program (for CNC machining Center and line cutting program), etc., used in 20% of the time by hand, reduce their working hours to 35 hours; from Japan in the early 80s will be three-dimensional cad / cam system for automotive panel die.Currently, the physical parts scanning input, map lines and data input, geometric form, display, graphics, annotations and the data is automatically programmed, resulting in effective control machine tool control system of post-processing documents have reached a high level; computer Simulation (CAE) technology has made some achievements.At high levels, CAD / CAM / CAE integration, that data is integrated, can transmit information directly with each other. Achieve network.Present.Only a few foreign manufacturers can do it.Chinas mold industry and its development trend模具工业现状 Die & Mould Industry Status由于历史原因形成的封闭式、“ 大而全” 的企业特征，我国大部分企业均设有模具车间，处于本厂的配套地位，自 70 年代末才有了模具工业化和生产专业化这个概念。 Due to historical reasons for the formation of closed, big and complete enterprise features, most enterprises in China are equipped with mold workshop, in factory matching status since the late 70s have a mold the concept of industrialization and specialization of production. Production efficiency is not high, poor economic returns. Mold production industry is small and scattered, cross-industry, capital-intensive, professional, commercial and technical management level are relatively low.据不完全统计，全国现有模具专业生产厂、产品厂配套的模具车间（分厂）近17000家，约60万从业人员，年模具总产值达200亿元人民币。 According to incomplete statistics, there are now specialized in manufacturing mold, the product supporting mold factory workshop (factory) near 17 000, about 600 000 employees, annual output value reached 20 billion yuan mold.However, the existing capacity of the mold and die industry can only meet the demand of 60%, still can not meet the needs of national economic development.At present, the domestic needs of large, sophisticated, complex and long life of the mold also rely mainly on imports. According to customs statistics, in 1997 630 million U.S. dollars worth of imports mold, not including the import of mold together with the equipment; in 1997 only 78 million U.S. dollars export mold.At present the technological level of China Die & Mould Industry and manufacturing capacity, Chinas national economy in the weak links and bottlenecks constraining sustainable economic development.1、模具工业产品结构的现状 3.1 Research on the Structure of industrial products moldIn accordance with the division of China Mould Industry Association, China mold is divided into 10 basic categories, which, stamping die and plastic molding two categories accounted for the main part.Calculated by output, present, China accounts for about 50% die stamping, plastic molding die about 20%, Wire Drawing Die (Tool) about 10% of the worlds advanced industrial countries and regions, the proportion of plastic forming die die general of the total output value 40%.我国冲压模大多为简单模、单工序模和符合模等，精冲模，精密多工位级进模还为数不多，模具平均寿命不足100万次，模具最高寿命达到1亿次以上，精度达到35um，有50个以上的级进工位，与国际上最高模具寿命6亿次，平均模具寿命5000万次相比，处于80年代中期国际先进水平。 Most of our stamping die mold for the simple, single-process mode and meet the molds, precision die, precision multi-position progressive die is also one of the few, die less than 100 million times the average life of the mold reached 100 million times the maximum life of more than accuracy 3 5um, more than 50 progressive station, and the international life of the die 600 million times the highest average life of the die 50 million times compared to the mid 80s at the international advanced level.我国的塑料成形模具设计，制作技术起步较晚，整体水平还较低。 Chinas plastic molding mold design, production technology started relatively late, the overall level of low.Currently a single cavity, a simple mold cavity 70%, and still dominant.A sophisticated multi-cavity mold plastic injection mold, plastic injection mold has been able to multi-color preliminary design and manufacturing.Mould is about 80 million times the average life span is about, the main difference is the large deformation of mold components, excess burr side of a large, poor surface quality, erosion and corrosion serious mold cavity, the mold cavity exhaust poor and vulnerable such as, injection mold 5um accuracy has reached below the highest life expectancy has exceeded 20 million times, the number has more than 100 chamber cavity, reaching the mid 80s to early 90s the international advanced level.2、模具工业技术结构现状 3.2 mold Present Status of Technology我国模具工业目前技术水平参差不齐，悬殊较大。 Technical level of Chinas mold industry currently uneven, with wide disparities.Generally speaking, with the developed industrial countries, Hong Kong and Taiwan advanced level, there is a large gap. 在采用CAD/CAM/CAE/CAPP等技术设计与制造模具方面，无论是应用的广泛性，还是技术水平上都存在很大的差距。 The use of CAD / CAM / CAE / CAPP and other technical design and manufacture molds, both wide application, or technical level, there is a big gap between both. In the application of CAD technology design molds, only about 10% of the mold used in the design of CAD, aside from drawing board still has a long way to go; in the application of CAE design and analysis of mold calculation, it was just started, most of the game is still in trial stages and animation; in the application of CAM technology manufacturing molds, first, the lack of advanced manufacturing equipment, and second, the existing process equipment (including the last 10 years the introduction of advanced equipment) or computer standard (IBM PC and compatibles, HP workstations, etc.) different, or because of differences in bytes, processing speed differences, differences in resistance to electromagnetic interference, networking is low, only about 5% of the mold manufacturing equipment of recent work in this task; in the application process planning CAPP technology, basically a blank state, based on the need for a lot of standardization work; in the mold common technology, such as mold rapid prototyping technology, polishing, electroforming technologies, surface treatment technology aspects of CAD / CAM technology in China has just started.Computer-aided technology, software development, is still at low level, the accumulation of knowledge and experience required. Most of our mold factory, mold processing equipment shop old, long in the length of civilian service, accuracy, low efficiency, still use the ordinary forging, turning, milling, planing, drilling, grinding and processing equipment, mold, heat treatment is still in use salt bath, box-type furnace, operating with the experience of workers, poorly equipped, high energy consumption.Renewal of equipment is slow, technological innovation, technological progress is not much intensity.Although in recent years introduced many advanced mold processing equipment, but are too scattered, or not complete, only about 25% utilization, equipment, some of the advanced functions are not given full play.缺乏技术素质较高的模具设计、制造工艺技术人员和技术工人，尤其缺乏知识面宽、知识结构层次高的复合型人才。 Lack of technology of high-quality mold design, manufacturing technology and skilled workers, especially the lack of knowledge and breadth, knowledge structure, high levels of compound talents. Chinas mold industry and technical personnel, only 8% of employees 12%, and the technical personnel and skilled workers and lower the overall skill level. Before 1980, practitioners of technical personnel and skilled workers, the aging of knowledge, knowledge structure can not meet the current needs; and staff employed after 80 years, expertise, experience lack of hands-on ability, not ease, do not want to learn technology.In recent years, the brain drain caused by personnel not only decrease the quantity and quality levels, and personnel structure of the emergence of new faults, lean, make mold design, manufacturing difficult to raise the technical level.3、模具工业配套材料，标准件结构现状 3.3 mold industry supporting materials, standard parts of present condition近10多年来，特别是“八五”以来，国家有关部委已多次组织有关材料研究所、大专院校和钢铁企业，研究和开发模具专用系列钢种、模具专用硬质合金及其他模具加工的专用工具、辅助材料等，并有所推广。 Over the past 10 years, especially the Eighth Five-Year, the State organization of the ministries have repeatedly Material Research Institute, universities and steel enterprises, research and development of special series of die steel, molds and other mold-specific carbide special tools, auxiliary materials, and some promotion. However, due to the quality is not stable enough, the lack of the necessary test conditions and test data, specifications and varieties less, large molds and special mold steel and specifications are required for the gap.In the steel supply, settlement amount and sporadic users of mass-produced steel supply and demand contradiction, yet to be effectively addressed.In addition, in recent years have foreign steel mold set up sales outlets in China, but poor channels, technical services support the weak and prices are high, foreign exchange settlement system and other factors, promote the use of much current.模具加工的辅助材料和专用技术近年来虽有所推广应用，但未形成成熟的生产技术，大多仍还处于试验摸索阶段，如模具表面涂层技术、模具表面热处理技术、模具导向副润滑技术、模具型腔传感技术及润滑技术、模具去应力技术、模具抗疲劳及防腐技术等尚未完全形成生产力，走向商品化。 Mold supporting materials and special techniques in recent years despite the popularization and application, but failed to mature production technology, most still also in the exploratory stage tests, such as die coating technology, surface treatment technology mold, mold guide lubrication technology Die sensing technology and lubrication technology, mold to stress technology, mold and other anti-fatigue and anti-corrosion technology productivity has not yet fully formed, towards commercialization.Some key, important technologies also lack the protection of intellectual property.我国的模具标准件生产，80年代初才形成小规模生产，模具标准化程度及标准件的使用覆盖面约占20%，从市场上能配到的也只有约30个品种，且仅限于中小规格。 Chinas mold standard parts production, the formation of the early 80s only small-scale production, standardization and standard mold parts using the coverage of about 20%, from the market can be assigned to, is just about 30 varieties, and limited to small and medium size.Standard punch, hot runner components and other supplies just the beginning, mold and parts production and supply channels for poor, poor accuracy and quality.4、模具工业产业组织结构现状 3.4 Die & Mould Industry Structure in Industrial Organization我国的模具工业相对较落后，至今仍不能称其为一个独立的行业。 Chinas mold industry is relatively backward and still could not be called an independent industry. Mold manufacturer in China currently can be divided into four categories: professional mold factory, professional production outside for mold; products factory mold factory or workshop, in order to supply the product works as the main tasks needed to die; die-funded enterprises branch, the organizational model and professional mold factory is similar to small but the main; township mold business, and professional mold factory is similar.Of which the largest number of first-class, mold production accounts for about 70% of total output.Chinas mold industry, decentralized management system.There are 19 major industry sectors manufacture and use of mold, there is no unified management of the department.Only by China Die & Mould Industry Association, overall planning, focus on research, cross-sectoral, inter-departmental management difficulties are many.Mold is suitable for small and medium enterprises organize production, and our technical transformation investment tilted to large and medium enterprises, small and medium enterprise investment mold can not be guaranteed.Including product factory mold shop, factory, including, after the transformation can not quickly recover its investment, or debt-laden, affecting development.虽然大多数产品厂的模具车间、分厂技术力量强，设备条件较好，生产的模具水平也较高，但设备利用率低。 Although most products factory mold shop, factory technical force is strong, good equipment conditions, the production of mold levels higher, but equipment utilization rate.我国模具价格长期以来同其价值不协调，造成模具行业“自身经济效益小，社会效益大”的现象。 Price has long been Chinas mold inconsistent with their value, resulting in mold industry own little economic benefit, social benefit big phenomenon.Dry as dry mold mold standard parts, standard parts dry as dry mold with pieces of production. Dry with parts manufactured products than with the mold of the class of anomalies exist.模具的发展趋势 4 Die trend1、模具CAD/CAE/CAM正向集成化、三维化、智能化和网络化方向发展 4.1 mold CAD / CAE / CAM being integrated, three-dimensional, intelligent and network direction（1）模具软件功能集成化 (1) mold software features integratedDie software features of integrated software modules required relatively complete, while the function module using the same data model, in order to achieve Syndicated news management and sharing of information to support the mold design, manufacture, assembly, inspection, testing and production management of the entire process to achieve optimal benefits.Series such as the UK Delcams software will include a surface / solid geometric modeling, engineering drawing complex geometry, advanced rendering industrial design, plastic mold design expert system, complex physical CAM, artistic design and sculpture automatic programming system, reverse engineering and complex systems physical line measurement systems.：Pro/ENGINEER、UG和CATIA等。 A higher degree of integration of the software includes: Pro / ENGINEER, UG and CATIA, etc.Shanghai Jiaotong University, China with finite element analysis of metal plastic forming systems and Die CAD / CAM systems; Beijing Beihang Haier Software Ltd. CAXA Series software; Jilin Gold Grid Engineering Research Center of the stamping die mold CAD / CAE / CAM systems .（2）模具设计、分析及制造的三维化 (2) mold design, analysis and manufacture of three-dimensional传统的二维模具结构设计已越来越不适应现代化生产和集成化技术要求。 Two-dimensional mold of traditional structural design can no longer meet modern technical requirements of production and integration. Mold design, analysis, manufacturing three-dimensional technology, paperless software required to mold a new generation of three-dimensional, intuitive sense to design the mold, using three-dimensional digital model can be easily used in the product structure of CAE analysis, tooling manufacturability evaluation and CNC machining, forming process simulation and information management and sharing.Such as Pro / ENGINEER, UG and CATIA software such as with parametric, feature-based, all relevant characteristics, so that mold concurrent engineering possible.In addition, Cimatran company Moldexpert, Delcams Ps-mold and Hitachi Shipbuilding of Space-E/mold are professional injection mold 3D design software, interactive 3D cavity, core design, mold base design configuration and typical structure .Australian company Moldflow realistic three-dimensional flow simulation software MoldflowAdvisers been widely praised by users and applications. China Huazhong University of Science have developed similar software HSC3D4.5F and Zhengzhou University, Z-mold software.For manufacturing, knowledge-based intelligent software function is a measure of die important sign of advanced and practical one. Such as injection molding experts Cimatrons software can automatically generate parting direction based parting line and parting surface, generate products corresponding to the core and cavity, implementation of all relevant parts mold, and for automatically generated BOM Form NC drilling process, and can intelligently process parameter setting, calibration and other processing results.（3）模具软件应用的网络化趋势 (3) mold software applications, networking trend随着模具在企业竞争、合作、生产和管理等方面的全球化、国际化，以及计算机软硬件技术的迅速发展，网络使得在模具行业应用虚拟设计、敏捷制造技术既有必要，也有可能。 With the mold in the enterprise competition, cooperation, production and management, globalization, internationalization, and the rapid development of computer hardware and software technology, the Internet has made in the mold industry, virtual design, agile manufacturing technology both necessary and possible.The United States in its 21st Century Manufacturing Enterprise Strategy that the auto industry by 2006 to achieve agile manufacturing / virtual engineering solutions to automotive development cycle shortened from 40 months to 4 months.2、模具检测、加工设备向精密、高效和多功能方向发展 4.2 mold testing, processing equipment to the precise, efficient, and multi-direction（1）模具检测设备的日益精密、高效 (1) mold testing equipment more sophisticated, efficient精密、复杂、大型模具的发展，对检测设备的要求越来越高。 Sophisticated, complex, large-scale mold development, testing equipment have become increasingly demanding.Precision Mould precision now reached 2 3m, more domestic manufacturers have to use Italy, the United States, Japan and other countries in the high-precision coordinate measuring machine, and with digital scanning.Such as Dongfeng Motor Mould Factory not only has the capacity 3250mm 3250mm Italian coordinate measuring machine, also has a digital photography optical scanner, the first in the domestic use of digital photography, optical scanning as a means of spatial three-dimensional access to information, enabling the establishment from the measurement of physical model output of engineering drawings the whole process of mold making, reverse engineering a successful technology development and applications.This equipment include: second-generation British Renishaw high-speed scanners (CYCLON SERIES2) can be realized and contact laser probe complementary probe, laser scanner accuracy of 0.05mm, scanning probe contact accuracy of 0.02 mm. Another German company GOM ATOS portable scanners, Japan Rolands PIX-30, PIX-4 desktop scanner and the United Kingdom Taylor Hopsons TALYSCAN150 multi-sensor, respectively Three-dimensional scanner with high speed, low-cost and functional composite and so on.（2）数控电火花加工机床 (2) CNC EDM日本沙迪克公司采用直线电机伺服驱动的AQ325L、AQ550LLS-WEDM具有驱动反应快、传动及定位精度高、热变形小等优点。 Japan Sodick linear motor servo drive using the companys AQ325L, AQ550LLS-WEDM have driven fast response, transmission and high positioning accuracy, the advantages of small thermal deformation.Switzerland Chanmier company NCEDM with P-E3 adaptive control, PCE energy control and automatic programming expert systems.Others also used the powder mixed EDM machining technology, micro-finishing pulse power and fuzzy control (FC) technologies.（3）高速铣削机床(HSM) (3) high-speed milling machine (HSM)铣削加工是型腔模具加工的重要手段。 Milling is an important means of cavity mold. The low-temperature high-speed milling with the workpiece, cutting force is small, smooth processing, processing quality, processing efficiency (for the general milling process 5 to 10 times) and can process hard materials (60HRC) and many other advantages.Ruishikelang company UCP710-type five-axis machining center, machine tool positioning accuracy up to 8m, home-made closed-loop vector control spindle with a maximum speed 42000r/min.Italy RAMBAUDIs high-speed milling, the processing range of up to 2500mm 5000mm 1800mm, speed up 20500r/min, cutting feed speed of 20m/min. HSM generally used large, medium-sized mold, such as motor cover mold, die casting mold, large plastic surface machining, the surface precision up to 0.01mm.4.3、rapid economic modeling techniques缩短产品开发周期是赢得市场竞争的有效手段之一。 Shorten the product development cycle is an effective means of market competition to win one.Compared with the traditional mold process, fast economic modeling technology is a short molding cycle, the characteristics of low cost, precision, and life can meet the production needs, overall economic efficiency is more significant in the mold manufacturing technology, specifically the following main technology.(1) rapid prototyping and manufacturing (RPM).It consists of three-dimensional laser lithography (SLA); laminated profile manufacturing (LOM); laser powder sintering prototyping (SLS); Fused Deposition Molding (FDM) and three-dimensional printing forming technology (3D-P) and so on. (2) the surface forming tooling.It refers to the use of spray, chemical corrosion, electroforming and new method for the formation of the cavity surface and a fine pattern technology. (3) Casting forming tooling.There are bismuth tin alloy tooling, zinc alloy tooling, resin composite forming technology and silicon rubber mold molding technology.
