摘要
在目前激烈的市场竞争中，产品投入市场的迟早往往是成败的关键。模具是高质量、高效率的产品生产工具，模具开发周期占整个产品开发周期的主要部分。因此，如何在保证质量、控制成本的前提下缩短模具开发周期是值得认真考虑的问题。
模具开发周期包括模具设计、制造、装配与试模等阶段。所阶段出现的问题都会对整个开发周期都有直接的影响，但有些因素的作用是根本的、全局性的。人的因素及设计质量就是这样的因素。
缩短设计周期并提高设计质量是缩短整个模具开发周期的关键之一。模块化设计就是利用产品零部件在结构及功能上的相似性，而实现产品的标准化与组合化。大量实践表明，模块化设计能有效减少产品设计时间并提高设计质量。因此本文探索在模具设计中运用模块化设计方法。
某些模具零件（如凸凹模）的形状和尺寸由产品决定因而无法在模块设计时预见到，所以只能按常见形状设计模块（如圆形或矩形的冲头）,适用面窄；某些模具零件（如冲压模的工件定位零件）虽然互相配合执行某一功能，但它们的空间布置难寻规律与共性，因此即使按功能划分也不能产生模块。
本文介绍了注射模具的特点及发展趋势，叙述了三通管注射模具设计与计算的详细过程，介绍了该塑件成型工艺、注射模具的结构特点与工作过程, 阐述了在有斜滑块抽芯的注射模设计中应注意的事项

Abstract

Launching a new product in time is the key to success in the current fierce market competition. Mold as the tool which is used to ensure the high-quality and high-efficiency production, its development circle takes up the main part of the entire development circle of the product.
Thus, it is necessary to consider how to shorten the entire development circle of model on the premise that the quality can be ensured and the cost can be cut.
The development of model includes designing, producing, assembling and examining steps etc. the problems which appear in every step can influence the whole developing process directly. There are many factors influence the development process, some of them influence it radically, entirely, such as the designer and the quality of design.
Shortening the period and enhancing the quality of design are the keys to shorten to entire development circle of model. Modular design refers to utilize the similarity in construction and function between the components to achieve the standardization and assibilation of products. Practices show that modular design is an effective way to reduce the time and enhance the quality of products .This paper mainly explores the method of applying the modular design in model design.
Shape and size of some model spares, such as convex and cave mold are decided by certain product, as the result, they can not be foresaw in the
model piece design, people only can design the model according to the common shapes such as the blunt head of circular or rectangle. Meanwhile, although some model spares such as blunt press the fixed position spare can work in coordination to carry out certain function, it is hard to find the regulation and similarity in their spaces arrangement, so it also cannot produce a model piece even according to their function.
The characteristics and developments of injection mould will be introduced in this paper. The designing and calculating of injection mould of microphone will be stated in detail. The forming process of the product and the structure characteristics as well as working process of the injection mould will be introduced .The attention should be paid in the design of the injection mould for the part with lifters also will be stated.

内容简介：: 外文文献翻译第 14 页共 14 页 The molding tool CADGathers the technique Contents brief summary:Pass to analyze the calculator the assistance inject the mold design with make in the each link commonly shared of technique with information, this text announces to public to inject the mold CAD gathers technical and basic content, and the research heat that put forward it orders with trend. 0, preface The molding tool CAD gathers the technique is an important molding tool forerunner manufacturing technique, is a the item reforms with the high technique traditional technical and important key in molding tool technique.From 6 5 plan beginning, Our country contain many molding tools business enterprise adoption CAD technique, especially recent years, the technical application in CAD is more and more widespread with thorough, shortened consumedly molding tool design period, Increases to make the mold quantity with the manufacturing ability that complicated molding tool.However, gather to the molding tool CAD because of many business enterprises technique cognition shortage, investment take the blindness, cant produce result nicely, Result in very big and wasted.This text gathers for the plastics molding tool CAD technique and its applications announce some standpoint, provide everybody consults. 1, the plastics molding tool CAD gathers techniqueThe manufacturing of the plastics molding tool comtains the construction design of the shape design, molding tool and the number of the analysis, molding tools that include the plastics products control to process( , electricity process, the line incises etc.), throw the light with go together with to try the mold and take shape manufacturing etc. quickly.The each link a CAD for involving unit technique has: The shape design( CAD) with the construction, fast anti of the product shape beg( RE), construction analysis with excellent turn the design( CAE), lend support to the manufacturing( CAM) and process the process conjecture imitate true( SIMULATION), product and molding tools take shape( RP) quickly, assistance craft process( CAPP) with product data management technique( PDM) etc.The plastics molding tool CAD gathers technique, Is to gather plastics molding tool manufacturing process a various units for involving technique get up, unify the database to deliver the format with the document, realize the information gather share with the data resources, from but shorten the design manufacturing period of the molding tool consumedly, Increases to make the mold quantity.2, the CAD design of the plastics product begs with fast anti of the shapeThe plastics molding tool that proceed the square one designs the manufacturing is the design of the a product.The traditional product design method is a design to product of three s conceive outline to use two plane chart papers expresses to come out, marking clearly the craft and starting construction the method on the diagram paper, This kind of method comes to a decision the simple of a design sketch and cants control to make the quantity directly.The modern design method is a design establish the product directly on the computer of three the model of , According to the product three models proceed the molding tool construction the design and excellent turn the design, Design according to the molding tool construction again three models proceed to process to weave the distance and establishment crafts plan.This kind of method makes product model design, molding tool construction design, process to weave distance and technological designs regard a data as the foundation, realizing the data share, Can not only increases to design the efficiency quickly, but also can guarantee the quantity, decline low cost. The source of the computer a product model has three kinds of: Making use of the CAD system software proceeds the product model the design and make use of the real object measures fast anti in proceeding beg to set up the mold and make use of the standard format document of the other the system of CAD.Source method that aim at these three kinds of products model, Have studied every kind of technique now to the design efficiency that increases product model with quantity.The underneath further analyzes every kind of technical content with the characteristics. Making use of the CAD system software proceeds the product model design, Its technique includes primarily two s are several why the sketch draws, two the parameter of s turn the design of the sketch, three entity shape design, three characteristic shape design, three the parameter of s turn the entity shape the design, three curved face shape design, free shape in space design, the external appearance of the product exaggerates, product of dynamic advertise to design the etc.These softwareses contain many typical representatives.Two the software of s have: ME10, CADKEY, AUTOCAD, DHCAD, Genis, etc. of Sigraph; three the software of s have: UGII, PRO/ E, IDEAS, CATIA, etc. of EUCLID; free shape in product and advertise the software of the design have: Alias, etc. of CDRS.Two s are several why the sketch draws is to make use of the flat surface CAD software draw the spare parts sketch, then replace the handicraft painting with the calculator; but two the parameter of s turn, Then the calculator realizes the sketch changes the deal designs, making modification more convenient; three shape designs is a true shape that the product that the arithmetic figure turn design, it expressed completely product, Can be further to designs for the molding tool, analysis with processes the mathematics model of the necessity of offering; the free shape in space design is the art of the product shape to design, making product been not only is a function product, but also art article; It is every kind of need that the external appearance of the product exaggerate that product of the result designs, making product more beautiful, the color can attract people more; the dynamic advertisement design of the product is a result that design to make to promote the advertisement directly the product, Proceed the market expansion. Making use of the real object measures fast anti of proceeding beg to set up mold is current investigative a little bit hot of a, It is an important technique that product imitate the type foundation go forward a line of the product modification designs.Its basic principle is to passes three coordinateses measure the machine, laser measure machine or electronicses copy the few to proceed to scan the diagraph to the real object, The data of large quantity that arithmetic figure turn that gets to measures the acquisition orders anti that send into the high class CAD software beg mold piece or appropriative anti beg the software inside, anti beg the software can read directly a data cluster, Combining can proceed the editor, filter, tidy up, beg the to a data cluster, row preface, part modification and reorganization, then automatic born curved face, It is end to acquire together the real object precision is consistent of or computer a product model that pass through reforms.This way can increases biggest new product design velocity.Current mature curved face anti beg to set up the mold software has: Surfacer, Cimatronrenge, etc. of Strim100. Make use of the standard format document of the other the system of CAD to set up the mold, this way than convenience.Because the world of the market turns with the technical development in the network of INTERNET, The CAD technique exchanges of the molding tool business enterprise with cooperate to have many pass the CAD document method proceed.Because the CAD system category is more, therefore documentary format must follow the international standard, Such as the DXF, IGES, STEP, VDA, etc. of STL.Pass to read standard format document to establish directly or establish the product model after modifying, since can quickly, deepen the customer and the exchanges of the molding tool factory house, Also can shorten the product the design the period. 3, the CAD design of the molding tool and analysisThe CAD design of the molding tool, analysis, Include to divide the type, certain type according to the product model molding tool of proceeding the design with the type , molding tool structural and detailed design, the plastics fills process analysis etc. a few aspects.Make use of the advanced characteristic shape software,such as PRO/ E, etc. of UGII, the very easily certain dividing the type, Born top and bottom mold with mold , then the proceeding flows a way, sprinkle a people and cool off the pipe line of arrange etc.Made sure these designses data hereafter, then make use of the molding tool analysis software, Proceed such as the MOLDFLOW, CFLOW the plastics take shape the process analysis.According to the software of MOLDFOLW with it of the material, craft database of plentifulness, pass the importation take shape the craft parameter, Can the development imitate the true analysis plastics to inject in note mold the process flows the circumstance( the plastics with sprinkle a people more inject remits to flow the analysis of ), analyze the temperature pressure variety circumstance and analyze to note a remaining should dint etc., According to analyze the circumstance to the rationality that check the molding tool construction, flow quantity problem etc. of the rationality, product of the appearance.For example whether the esse sprinkles to note the system not reasonable, appear to flow way with sprinkle a position size not appropriate, Cant equilibrium alive with type ; whether to exsit product construction absurdity or molding tool constructions or not is not reasonable, appearing the product dissatisfied( namely short shoot the phenomenon); whether to cool off asymmetry or not, the influence produces the efficiency with product quantity; Whether the esse notes the craft of wrong, appear the song of of the product transform etc.The molding tool passes the CAD the design with analyze, can dissolve mistake at design the stage, increase to try once the mold the success the rate. At plastics molding tool design with analyze to apply many new computer-aideds technique this stage, if the parameter turns technique, characteristic shape technique, database technique etc.There is many standards piece in the plastics molding tool, Turn such as the standard mold a parameter for outing organization, sprinkling noting system, cooling system.etc. can adopting basing on database managing the characteristic shape design method proceed the design or establish the standard a , like this since can realize the data share, Can satisfy the customer again to the at any time modifying of the design, make the design analysis of the molding tool fast, accurate, efficiently.The parameter turns the characteristic shape can not only describe the product completely then several why sketch information, And can acquire accuracy, material and assemble etc. informations of the product, its a product for establishing model is a kind of apting to handle and can reflect design intention with process the model of the characteristic.Therefore, The parameter turns the characteristic shape technique is an one of the most important technique in process in manufacturing in molding tools. 4, the technical application in CAM of the molding tool, process to imitate true and manufacturing The calculator assistance manufacturing( CAM) technique of the molding tool applies primarily in the aspects of counting to control processing, line incising to process, electricity spark processing to wait.The technique of CAM rises in the type , type of the complicated molding tool and the of the electrodes process particularly more important function.Its main technique characteristics includes: (1) the , processes the knife have the track excellent to turn the programming with the instruction of NC creation,(2) the knife has the category, characteristic to establish with the material ,(3) slicing the process the craft parameter to really settle,(4) The commonness slices the to slice with the high speed the characteristic that process controls,(5) over slice the check with process the superficial accuracy control,(6) processing the computer entity of the process imitate the realistic ,(7) The computer control number controls the technique of DNC and clusters of the machine bed control the technical and applied etc. Need the CAD specially in technical application in CAM three product model data.More profession computer plait distance software,such as MASTERCAM, UNIMOD, etc. of CIMATRON, when the plait distance of many curved faces processes have the higher request to the curved face model of the product, Intend with the high accuracy of the curved face to match such as the directional consistency, curved face in U, V of the close together curved face, inclined rate in curved face continuous variety etc.In high class CAD/ the integral whole of CAM turn system,( such as UGII, PRO/ E) Because making use of the parameter turns the characteristic shape design with same database technique, making the type of the product model data, molding tool have the track data to have got the inside contact with the type model data, knife, The modification knife of the product model has the track to also modify automatically. The molding tool processes the entity imitates the true technique more and more mature, also is more and more valued by people.It is mimicry machine bed that processing the entity imitate process the process on the computer, can keep the result that view reflect process, Can takes the gauge of directly quantity that after processing spare parts, can check the mistake that process.At check quantity that after processing spare parts, can at the computer is last to process behind of the entity model proceeds the aleatoric slices, Measure its size directly with the accuracy.Therefore, it can dissolve mistake at process the stage of craft plait distance design, reduce to repair after processing with return the work, increases consumedly the manufacturing efficiency of the molding tool with quantity. 5, plastics product and its molding tools take shape the manufacturing quickly Plastics product and its molding tools use the computer CAD technique design after completing, can pass the fleetness take shape the technique make.This is the manufacturing technique of a kind of all new concept, It abandoned the traditional machine processes the method.Its take shape principle is three CAD entity models are long-lost set up a series of a layer data of the thickness, make use of the laser take shape machine or others take shape the equipments read these datas, Increase the method technique with the material, pile up the each layer to take shape one by one in order.This technique calls the fleetness to take shape the technique automatically.( Rapid Prototype)It is also a CAD to gather the technical importance constitutes the part. The first pedestal takes shape the equipments quickly to bear in the United States a company in 1987, because of its characteristics is to has nothing to do with the complicated degree of the product of the manufacturing, bringing the manufacturing industry the enormous vibration.Henceforth decade, Take shape quickly the technique be flown to develop soon, the category of the equipments also piles up one after another, Turn from the material the method can is divided into the laser with not the laser burns the knot method( SLS), solid surface layer shape method( SGC), layer a manufacturing method( LOM) and melt to sink to accumulate the method( FDM), district constituency glues the knot method( DSPC), laser spirit to sink to accumulate method( SALD) etc. mutually.Every kind of method characteristics is: The method of SLA is applied at the earliest stage of took shape the technique quickly, the early market occupied the bigger cent sum, but is narrow because of the material scope, the cost is higher, taking shape the piece was heat-proof and bore the burthen with applied color the ability low, The recent years was gradually replaced by the other method.The method of FDM because of taking shape the speed quick, the cost is low, get the good application in plastics product profession, because the size of the spare parts is small, accuracy bad, Also suffer certainly of restrict.The method of LOM because of adoption paper or is outline edge that thin slice plastics, the cost is low, and the laser projects light upon each layer only, as a result take shape the speed quick, But the product surface quantity is bad.The method of SLS proceeds to burn the knot with the laser, adoptive material than wide, if the plastics, anticipates, porcelain and ceramics, metals etc. all can take shape, taking shape the piece is heat-proof and bear the burthen with apply color the ability stronger, Have the extensive and applied foreground.The other method also gets the application in some special kinds process. According to above take shape the method characteristics, take shape the technical function quickly to consist in primarily: The manufacturing useds for the design with the on trial product model, make to used for the small the molding tool that batch quantity produce to process with the special spare parts in small batch quantity.Take shape the product model of the technique manufacturing quickly in the aspects of material the ratio tradition processes the product model of the method manufacturing has the difference, But in shape and sizes almost complete similar, and there is certain machine strength, can make the function experiment, handles through surface at the same time, looking similar to true product, Can advertise the propaganda material.Take shape the molding tool of the technique manufacturing quickly, Is a soft material to take shape the mold( the mold of , wreath oxygen resin mold, rubber mold, low orders the metal alloy casts mold etc.) primarily to synthesize the hard type in material mold with porcelain and ceramics or metals s now.Hard mold in manufacturing the hour can take shape with the fleetness the spare parts makes the female die, Create first the soft mold between wreath oxygen resin mold or other material, sprinkle to note porcelain and ceramics or gypsum molds in soft mold, then sprinkle the steel of steel mold; or sprinkle the admixture that note in soft mold chemistry contain steel powder glue knot, Proceed to burn to become the steel mold.Take shape the steel mold of the technique manufacturing quickly to process after needing further did to throw light etc., make into the small batch quantity produce of note the mold of .Because the molding tool sprinkles to note or burn the knot with the steel powder but, Material and common molding tool steel contain certain margin, therefore, the life span is shorter, cans make to manufacture on a trial basis product or small batch quantities produce.Moreover, taking shape the technique quickly can also manufacture the special spare parts, If make with the metallurgy powder legal system the metals electrode, nicety cast the legal system makes the copper electrode, mold legal system makes graphite electrode etc. Take shape the technique creation molding tool quickly to model the equipments with the product, all is STL to read CAD system creation or CLI etc. document format datas, Different document format data to the product accuracy of the creation contain bigger margin, therefore, study the system of CAD to take shape quickly the document format of the equipments output to have the very important meaning. 6, the molding tool CAD gathers technical development trend A calculator for saying, molding tool CAD gathering technique is applying in molding tool making each link assistance technique on the with each link information that realizes the technique gathers.Obviously, The information gathers unify with data the management is a key.The information of the product is to pierces through in the design, analyze, process, examine, assemble a stage, Fluency, solution data format that realizes each link information standardizes and the data maintenance is a point with future CAD that share to gather technique development.The system of PDM emergence is to resolve this problem brought the first light of day.It is molding tool business enterprise application CAD that the system of PDM puts into practice gather technical and important lesson.Design in molding tool manufacturing aspect,The intelligence that imply the research, high speed that abundant experts knowledge turn molding tool CAD/ the system of CAM slices the processes and its plait distance etc. is a trend that future study the development.塑料模具CAD集成技术内容提要：通过分析计算机辅助注射模设计和制造的各个环节中共享的技术和信息，本文揭示了注射模CAD的集成技术的根本内涵，并提出了它的研究热点和趋势。引言模具CAD集成技术是一项重要的模具先进制造技术, 是一项用高技术改造模具传统技术的重要关键技术。从六五计划开始, 我国有许多模具企业采用CAD技术, 特别是近年, CAD技术的应用越来越普遍和深入, 大大缩短了模具设计周期, 提高了制模质量和复杂模具的制造能力。然而, 由于许多企业对模具CAD集成技术认识不足, 投资带有盲目性, 不能很好地发挥作用, 造成了很大的浪费。本文就塑料模具CAD集成技术及其应用发表一些观点, 供大家参考。 1、塑料模具CAD集成技术塑料模具的制造, 包括塑料产品的造型设计、模具的结构设计及分析、模具的数控加工(铣削、电加工、线切割等)、抛光和配试模以及快速成形制造等。各个环节所涉及的CAD单元技术有: 造型和结构设计(CAD)、产品外形的快速反求(RE)、结构分析与优化设计(CAE)、辅助制造(CAM)、加工过程虚拟仿真(SIMULATION)、产品及模具的快速成形(RP)、辅助工艺过程(CAPP)和产品数据管理技术(PDM)等。塑料模具CAD集成技术, 就是把塑料模具制造过程所涉及的各项单元技术集成起来, 统一数据库和文件传输格式, 实现信息集成和数据资源共享, 从而大大缩短模具的设计制造周期, 提高制模质量。 2、塑料产品的CAD设计与外形的快速反求进行塑料模具设计制造的第一步是塑件产品的设计。传统产品设计方法是设计者对产品的三维构思用二维平面图纸表达出来, 图纸上标明工艺及施工方法, 这种方法决定了所设计图形的简单性及不能直接控制制造质量。现代设计方法是设计者在电脑上直接建立产品的三维模型, 根据产品三维模型进行模具结构设计及优化设计, 再根据模具结构设计三维模型进行加工编程及编制工艺计划。这种方法使产品模型设计、模具结构设计、加工编程及工艺设计都以3D数据为基础, 实现数据共享, 不仅能快速提高设计效率, 而且能保证质量, 降低成本。电脑塑件产品模型的来源有三种: 利用CAD系统软件进行产品模型设计、利用实物测量进行快速反求建模、利用其它CAD系统的标准格式文件。针对这三种产品模型的来源方式, 目前已研究出各种技术来提高产品模型的设计效率和质量。下面进一步分析各种技术的内涵和特点。利用CAD系统软件进行产品模型设计,其技术主要包括二维几何图形的绘制、二维参数化图形的设计、三维实体造型设计、三维特征造型设计、三维参数化实体造型设计、三维曲面造型设计、空间自由造型设计、产品的外观渲染、产品的动态广告设计等等。这些软件有许多典型的代表。二维软件有: ME10、CADKEY、AUTOCAD、DHCAD、Genis、Sigraph等; 三维软件有: UGII、PRO/E、IDEAS、CATIA、EUCLID等; 产品自由造型及广告设计的软件有: Alias、CDRS等。二维几何图形的绘制是利用平面CAD软件绘制零件图形, 即用计算机代替手工绘图; 而二维参数化, 即计算机实现了图形的变量设计, 使修改更加方便; 三维造型设计是数字化的产品的真实形状设计, 它完全表达了产品, 能够进一步为模具设计、分析和加工提供必要的数学模型; 空间自由造型设计是产品外形的艺术设计, 使产品不仅是功能产品, 也是艺术品;产品的外观渲染是产品的效果设计, 使产品更加美观、颜色更加能迎合人们的各种需求; 产品的动态广告设计是将产品设计的结果直接制作宣传广告, 进行市场推广。利用实物测量进行快速反求建模是目前研究的热点之一, 它是产品仿型基础上进行产品修改设计的重要技术。其基本原理是通过三座标测量机、激光测量机或电子抄数仪对实物进行扫描测量, 把测量所获得的数字化的大量数据点送入高级CAD软件的反求模块或专用的反求软件中, 反求软件可直接读取点数据群, 并可对点数据群进行编辑、过滤、整理、求精、排序、局部修改与重组, 然后自动生成曲面, 最终获得同实物精确一致的或经改造的电脑塑件产品模型。这一方式可极大提高新产品设计速率。目前较成熟的曲面反求建模软件有: Surfacer, Cimatronrenge, Strim100等。利用其它CAD系统的标准格式文件来建模, 这一方式较方便。由于市场的全球化和INTERNET网络技术的发展, 模具企业的CAD技术交流和合作有许多通过CAD文件方式进行。由于CAD系统种类较多, 因此文件的格式就必须遵循国际标准, 如DXF、IGES、STEP、VDA、STL等。通过读取标准格式文件来直接建立或修改后建立产品模型, 既可加快、加深用户与模具厂家的交流, 也可缩短产品设计周期。 3、模具的CAD设计与分析模具的CAD设计、分析, 包括根据产品模型进行模具分型面的设计、确定型腔和型芯、模具结构的详细设计、塑料充填过程分析等几个方面。利用先进的特征造型软件如PRO/E、UGII等很容易地确定分型面, 生成上下模腔和模芯, 再进行流道、浇口以及冷却水管的布置等。确定了这些设计数据以后, 再利用模具分析软件, 如MOLDFLOW、CFLOW进行塑料的成形过程分析。根据MOLDFOLW软件和它的丰富的材料、工艺数据库, 通过输入成形工艺参数, 可动态仿真分析塑料在注塑模腔内的注射过程流动情况(含多浇口注射时的塑料汇流纹分析)、分析温度压力变化情况、分析注塑件残余应力等, 根据分析情况来检查模具结构的合理性、流动状态的合理性、产品的质量问题等。比如是否存在浇注系统不合理, 出现流道和浇口位置尺寸不当, 无法平衡充满型腔; 是否存在产品结构不合理或模具结构不合理, 出现产品充不满(即短射现象); 是否冷却不均匀, 影响生产效率和产品质量; 是否存在
