毕业设计（外文翻译）模具设计与制造模具是制造业的重要工艺基础，在我国，模具制造属于专用设备制造业。中国虽然很早就开始制造模具和使用模具，但长期未形成产业。直到20世纪80年代后期，中国模具工业才驶入发展的快车道。近年，不仅国有模具企业有了很大发展，三资企业、乡镇（个体）模具企业的发展也相当迅速。 虽然中国模具工业发展迅速，但与需求相比，显然供不应求，其主要缺口集中于精密、大型、复杂、长寿命模具领域。由于在模具精度、寿命、制造周期及生产能力等方面，中国与国际平均水平和发达国家仍有较大差距，因此，每年需要大量进口模具。 中国模具产业除了要继续提高生产能力，今后更要着重于行业内部结构的调整和技术发展水平的提高。结构调整方面，主要是企业结构向专业化调整，产品结构向着中高档模具发展，向进出口结构的改进，中高档汽车覆盖件模具成形分析及结构改进、多功能复合模具和复合加工及激光技术在模具设计制造上的应用、高速切削、超精加工及抛光技术、信息化方向发展。 近年，模具行业结构调整和体制改革步伐加大，主要表现在，大型、精密、复杂、长寿命、中高档模具及模具标准件发展速度高于一般模具产品；塑料模和压铸模比例增大；专业模具厂数量及其生产能力增加；“三资”及私营企业发展迅速；股份制改造步伐加快等。从地区分布来看，以珠江三角洲和长江三角洲为中心的东南沿海地区发展快于中西部地区，南方的发展快于北方。目前发展最快、模具生产最为集中的省份是广东和浙江，江苏、上海、安徽和山东等地近几年也有较大发展。 虽然我国模具总量目前已达到相当规模，模具水平也有很大提高，但设计制造水平总体上落后于德、美、日、法、意等工业发达国家许多。当前存在的问题和差距主要表现在以下几方面：（1）总量供不应求 国内模具自配率只有70%左右。其中低档模具供过于求，中高档模具自配率只有50%左右。 （2）企业组织结构、产品结构、技术结构和进出口结构均不合理 我国模具生产厂中多数是自产自配的工模具车间（分厂），自产自配比例高达60%左右，而国外模具超过70%属商品模具。专业模具厂大多是“大而全”、“小而全”的组织形式，而国外大多是“小而专”、“小而精”。国内大型、精密、复杂、长寿命的模具占总量比例不足30%，而国外在50%以上。2004年，模具进出口之比为3.7:1，进出口相抵后的净进口额达13.2亿美元，为世界模具净进口量最大的国家。（3）模具产品水平大大低于国际水平，生产周期却高于国际水平 产品水平低主要表现在模具的精度、型腔表面粗糙度、寿命及结构等方面。 （4）开发能力较差，经济效益欠佳 我国模具企业技术人员比例低，水平较低，且不重视产品开发，在市场中经常处于被动地位。我国每个模具职工平均年创造产值约合1万美元，国外模具工业发达国家大多是1520万美元，有的高达2530万美元，与之相对的是我国相当一部分模具企业还沿用过去作坊式管理，真正实现现代化企业管理的企业较少。 造成上述差距的原因很多，除了历史上模具作为产品长期未得到应有的重视，以及多数国有企业机制不能适应市场经济之外，还有下列几个原因： （1）国家对模具工业的政策支持力度还不够 虽然国家已经明确颁布了模具行业的产业政策，但配套政策少，执行力度弱。目前享受模具产品增值税的企业全国只有185家，大多数企业仍旧税负过重。模具企业进行技术改造引进设备要缴纳相当数量的税金，影响技术进步，而且民营企业贷款十分困难。 （2）人才严重不足，科研开发及技术攻关投入太少 模具行业是技术、资金、劳动密集的产业，随着时代的进步和技术的发展，掌握并且熟练运用新技术的人才异常短缺，高级模具钳工及企业管理人才也非常紧张。由于模具企业效益欠佳及对科研开发和技术攻关重视不够，科研单位和大专院校的眼睛盯着创收，导致模具行业在科研开发和技术攻关方面投入太少，致使模具技术发展步伐不大，进展不快。 （3）工艺装备水平低，且配套性不好，利用率低 近年来我国机床行业进步较快，已能提供比较成套的高精度加工设备，但与国外装备相比，仍有较大差距。虽然国内许多企业已引进许多国外先进设备，但总体的装备水平比国外许多企业低很多。由于体制和资金等方面的原因，引进设备不配套，设备与附件不配套现象十分普遍，设备利用率低的问题长期得不到较妥善的解决。 （4）专业化、标准化、商品化程度低，协作能力差 由于长期以来受“大而全”“小而全”影响，模具专业化水平低，专业分工不细致，商品化程度低。目前国内每年生产的模具，商品模具只占40%左右，其余为自产自用。模具企业之间协作不畅，难以完成较大规模的模具成套任务。模具标准化水平低，模具标准件使用覆盖率低也对模具质量、成本有较大影响，特别是对模具制造周期有很大影响。 （5）模具材料及模具相关技术落后 模具材料性能、质量和品种问题往往会影响模具质量、寿命及成本，国产模具钢与国外进口钢材相比有较大差距。塑料、板材、设备性能差，也直接影响模具水平的提高。 目前，我国经济仍处于高速发展阶段，国际上经济全球化发展趋势日趋明显，这为我国模具工业高速发展提供了良好的条件和机遇。一方面，国内模具市场将继续高速发展，另一方面，模具制造也逐渐向我国转移以及跨国集团到我国进行模具采购趋向也十分明显。因此，放眼未来，国际、国内的模具市场总体发展趋势前景看好，预计中国模具将在良好的市场环境下得到高速发展，我国不但会成为模具大国，而且一定逐步向模具制造强国的行列迈进。“十一五”期间，中国模具工业水平不仅在量和质的方面有很大提高，而且行业结构、产品水平、开发创新能力、企业的体制与机制以及技术进步的方面也会取得较大发展。 模具技术集合了机械、电子、化学、光学、材料、计算机、精密监测和信息网络等诸多学科，是一个综合性多学科的系统工程。模具技术的发展趋势主要是模具产品向着更大型、更精密、更复杂及更经济的方向发展，模具产品的技术含量不断提高，模具制造周期不断缩短，模具生产朝着信息化、无图化、精细化、自动化的方向发展，模具企业向着技术集成化、设备精良化、产批品牌化、管理信息化、经营国际化的方向发展。我国模具行业今后仍需提高的共性技术有： （1）建立在CAD/CAE平台上的先进模具设计技术，提高模具设计的现代化、信息化、智能化、标准化水平。 （2）建立在CAM/CAPP基础上的先进模具加工技术与先进制造技术相结合，提高模具加工的自动化水平与生产效率。 （3）模具生产企业的信息化管理技术。例如PDM（产品数据管理）、ERP（企业资源管理）、MIS（模具制造管理信息系统）及INTERMET平台等信息网络技术的应用、推广及发展。 （4）高速、高精、复合模具加工技术的研究与应用。例如超精冲压模具制造技术、精密塑料和压铸模具制造技术等。 （5）提高模具生产效率、降低成本和缩短模具生产周期的各种快速经济模具制造技术。 （6）先进制造技术的应用。例如热流道技术、气辅技术、虚拟技术、纳米技术、高速扫描技术、逆向工程、并行工程等技术在模具研究、开发、加工过程中的应用（7）原材料在模具中成形的仿真技术。 （8）先进的模具加工和专有设备的研究与开发。 （9）模具及模具标准件、重要辅件的标准化技术。 （10）模具及其制品的检测技术。 （11）优质、新型模具材料的研究与开发及其正确应用。 （12）模具生产企业的现代化管理技术。 模具行业在“十一五”期间需要解决的重点关键技术应是模具信息化、数字化技术和精密、超精、高速、高效制造技术方面的突破。 随着国民经济总量和工业产品技术的不断发展，各行各业对模具的需求量越来越大，技术要求也越来越高。虽然模具种类繁多，但其发展重点应该是既能满足大量需要，又有较高技术含量，特别是目前国内尚不能自给，需大量进口的模具和能代表发展方向的大型、精密、复杂、长寿命模具。模具标准件的种类、数量、水平、生产集中度等对整个模具行业的发展有重大影响。因此，一些重要的模具标准件也必须重点发展，而且其发展速度应快于模具的发展速度，这样才能不断提高我国模具标准化水平，从而提高模具质量，缩短模具生产周期，降低成本。由于我国的模具产品在国际市场上占有较大的价格优势，因此对于出口前景好的模具产品也应作为重点来发展。根据上述需要量大、技术含量高、代表发展方向、出口前景好的原则选择重点发展产品，而且所选产品必须目前已有一定技术基础，属于有条件、有可能发展起来的产品。 根据“十一五”模具行业发展规划，“十一五”期间模具产品发展重点主要有如下几类： （1）汽车覆盖件模具冲压模具占模具总量的40%以上。汽车覆盖件模具主要为汽车配套，也包括为农用车、工程机械和农机配套的覆盖件模具，它在冲压模具中具有很大的代表性，模具大都是大中型，结构复杂，技术要求高。尤其是为轿车配套的覆盖件模具，要求更高，可以代表冲压模具的水平。此类模具我国已有一定的技术基础，已为中档轿车配套，但水平还不高，能力不足，目前满足率只有一半左右。中高档轿车覆盖件模具主要依靠进口，已成为汽车发展的瓶颈，极大的影响着车型开发。 （2）精密冲压模具 多工位级进模和精冲模代表了冲压模具的发展方向，精度要求寿命要求极高，主要为电子工业、汽车、仪器仪表、电机电器等配套。这两种模具，国内已有相当基础，并已引进了国外技术及设备，个别企业生产的产品已达到世界水平，但大部分企业仍有较大差距，供应总量不足，进口很多。 （3）大型精密塑料模具 塑料模具占模具总量近40%，而且这个比例还在上升。塑料模具中为汽车和家电配套的大型注塑模具，为集成电路配套的塑封模，为电子信息产业和机械及包装配套的多层、多腔、多材质、多色精密注塑模，为新型建材及节水农业配套的塑料异型材挤出模及管路和喷头模具等，目前虽然已有相当技术基础并正在快速发展，但技术水平与国外仍有较大差距，总量供不应求，每年的进口额达几亿美元。 （4）主要模具标准件 目前国内已有较大产量的模具标准件主要是模架、导向件、推杆推管、弹性元件等。这些产品不但国内配套大量需要，出口前景也很好，应继续大力发展。氮气缸和热流道元件主要依靠进口，应在现有基础上提高水平，形成标准并组织规模化生产。 （5）其他高技术含量的模具 占模具总量给8%的压铸模具中，大型薄壁精密压铸技术含量高，难度大。镁合金压铸模具目前虽然刚起步，但发展前景好，有代表性。子午线橡胶轮胎模具也是发展方向，其中活络模技术难度最大。与快速成型技术相结合的一些快速制模技术及相应的快速经济模具具有很好的发展前景。这些高技术含量的模具在“十一五”期间也应重点发展。6毕业设计（论文）任务书I、毕业设计(论文)题目：托板冲压模具设计II、毕 业设计(论文)使用的原始资料(数据)及设计技术要求：1. 托板零件图2.生产纲领：大等批量3.要求完成零件的冲压工艺分析和冲压工艺规程的编制。1) 分析冲件成形工艺及坯料展开 2）编制托板零件冲压工艺 3）完成托板模具设计III、毕 业设计(论文)工作内容及完成时间：1. 查阅相关资料，外文资料翻译（6000字符以上），撰写开题报告。第1周第2周2.绘制托板板冲件图，分析冲件成形工艺及坯料展开 第3周第6周3.编制托板冲压成形工艺规程； 第7周第8周4.绘制托板冲模总装图及零件图； 第9周第13周5.撰写毕业设计说明书（论文） 第14周第16周6.毕业设计审查，毕业答辩。 第17周 、主 要参考资料：1.冲模设计手册编写组.冲模设计手册.北京：冲模设计手册，19952. 陈为国.带缺口筒形件冲压工艺及模具设计.金属成形工艺，1998.23.王新华，袁联富编.冲模结构图册.北京：机械工业出版社，20034.罗益旋.冲压新工艺新技术及模具设计实用手册. 银声音像出版社，2004 5.

China although very already starts to make the mold and the use mold, but long-term has not formed the industry. Straight stabs 0 centuries 80s later periods, the Chinese mold industry only then drives into the development speedway. Recent years, not only the state-owned mold enterprise had the very big development, the three investments enterprise, the villages and towns (individual) the mold enterprises development also quite rapid .Although the Chinese mold industrial development rapid, but compares with the demand, obviously falls short of demand, its main gap concentrates precisely to, large-scale, is complex, the long life mold domain. As a result of in aspect and so on mold precision, life, manufacture cycle and productivity, China and the international average horizontal and the developed country still had a bigger disparity, therefore, needed massively to import the mold every year .The Chinese mold industry except must continue to sharpen the productivity, from now on will have emphatically to the profession internal structure adjustment and the state-of-art enhancement. The structure adjustment aspect, mainly is the enterprise structure to the specialized adjustment, the product structure to center the upscale mold development, to the import and export structure improvement, center the upscale automobile cover mold forming analysis and the structure improvement, the multi-purpose compound mold and the compound processing and the laser technology in the mold design manufacture application, the high-speed cutting, the superfinishing and polished the technology, the information direction develops .The recent years, the mold profession structure adjustment and the organizational reform step enlarges, mainly displayed in, large-scale, precise, was complex, the long life, center the upscale mold and the mold standard letter development speed is higher than the common mold product; The plastic mold and the compression casting mold proportion increases; Specialized mold factory quantity and its productivity increase; The three investments and the private enterprise develops rapidly; The joint stock system transformation step speeds up and so on. Distributes from the area looked, take Zhujiang Delta and Yangtze River delta as central southeast coastal area development quickly to mid-west area, south development quickly to north. At present develops quickest, the mold produces the most centralized province is Guangdong and Zhejiang, places such as Jiangsu, Shanghai, Anhui and Shandong also has a bigger development in recent years .Although our country mold total quantity had at present achieved the suitable scale, the mold level also has the very big enhancement, after but design manufacture horizontal overall rise and fall industry developed country and so on Yu De, America, date, France, Italy many. The current existence question and the disparity mainly display in following several aspects:(1) the total quantity falls short of demand domestic mold assembling oneself rate only ,about 70%. Low-grade mold , center upscale mold assembling oneself rate only has 50% about .(2) the enterprise organizational structure, the product structure, the technical structure and the import and export structure does not gatherin our country mold production factory to be most is from the labor mold workshop which produces assembles oneself (branch factory), from produces assembles oneself the proportion to reach as high as about 60%, but the overseas mold ultra 70% is the commodity mold. The specialized mold factory mostly is large and complete, small and entire organization form, but overseas mostly is small but, is specially small and fine. Domestic large-scale, precise, complex, the long life mold accounts for the total quantity proportion to be insufficient 30%, but overseas in 50% above 2004 years, ratio of the mold import and export is 3.7:1, the import and export balances the after net import volume to amount to 1.32 billion US dollars, is world mold net import quantity biggest country .(3) the mold product level greatly is lower than the international standardthe production cycle actually is higher than the international water broad product level low mainly to display in the mold precision, cavity aspect and so on surface roughness, life and structure .(4) develops the ability badly, economic efficiency unsatisfactory our country mold enterprise technical personnel proportion lowthe level is lower, also does not take the product development, frequently is in the passive position in the market. Our country each mold staff average year creation output value approximately ,ten thousand US dollars, overseas mold industry developed country mostly 15 to10,000 US dollars, some reach as high as 25 to10,000 US dollars, relative is our country quite part of molds enterprises also continues to use the workshop type management with it, truly realizes the enterprise which the modernized enterprise manages few To create the above disparity the reason to be very many, the mold long-term has not obtained the value besides the history in as the product which should have, as well as the most state-owned enterprises mechanism cannot adapt the market economy, but also has the following several reasons: .(1) country to mold industry policy support dynamics also insufficientlyalthough the country already was clear about has promulgated the mold profession industrial policy, but necessary policy few, carried out dynamics to be weak. At present enjoyed the mold product increment duty enterprise nation 185, the majority enterprise still the tax burden is only overweight. The mold enterprise carries on the technological transformations introduction equipment to have to pay the considerable amount the tax money, affects the technology advancement, moreover privately operated enterprise loan extremely difficult .(2) talented person serious insufficient, the scientific research development and the technical attack investment too urine mold profession is the technology, the fund, the work crowded industry, along with the time progress and the technical development, grasps the talented person which and skilled utilizes the new technology exceptionally short, the high-quality mold fitter and the enterprise management talent extremely is also anxious. Because the mold enterprise benefit unsatisfactory and takes insufficiently the scientific research development and the technical attack, the scientific research unit and the universities, colleges and institutes eye stares at is creating income, causes the mold profession invests too few in the scientific research development and the technical attack aspect, causes the mold technological development step not to be big, progresses not quick .(3) the craft equipment level to be low, also necessary is not good, the use factor low recent years our country engine bed profession progressed quickly, has been able to provide the quite complete precision work equipment, but compared with the overseas equipment, still had a bigger disparity. Although the domestic many enterprises have introduced many overseas advanced equipment, but the overall equipment level low are very more than the overseas many enterprises. As a result of aspect the and so on system and fund reason, introduces the equipment not not necessary, the equipment and the appendix not necessary phenomenon are extremely common, the equipment utilization rate low question cannot obtain the comparatively properly solution for a long time .(4) specialization, standardization, commercialized degree low, the cooperation ability because receives large and complete small and entire the influence since long ago, mold specialization level low, the specialized labor division is not careful, the commercialized degree is low. At present domestic every year produces mold, commodity mold minister 40% About, other for from produce uses for oneself. Between the mold enterprise cooperates impeded, completes the comparatively large-scale mold complete task with difficulty. Mold standardization level low, mold standard letter use cave rare is low also to the mold quality, the cost has a more tremendous influence, specially has very tremendous influence .(5) to the mold manufacture cycle) the mold material and the mold correlation technology falls the mold material performance, the quality and the variety question often can affect the mold quality, the life and the cost, the domestically produced molding tool steel and overseas imports the steel products to compare has a bigger disparity. Plastic, plate, equipment energy balance, also direct influence mold level enhancement .At present, our country economy still was at the high speed development phase, on the international economical globalization development tendency is day by day obvious, this has provided the good condition and the opportunity for the our country mold industry high speed development. On the one hand, the domestic mold market will continue high speed to develop, on the other hand, the mold manufacture also gradually will shift as well as the transnational group to our country carries on the mold purchase trend to our country extremely to be also obvious. Therefore, will take a broad view the future, international, the domestic mold market overall development tendency prospect will favor, estimated the Chinese mold will obtain the high speed development under the good market environment, our country not only can become the mold great nation, moreover certainly gradually will make the powerful nation to the mold the ranks to make great strides forward. 15 period, the Chinese mold industry level not only has the very big enhancement in the quantity and the archery target aspect, moreover the profession structure, the product level, the development innovation ability, enterprises system and the mechanism as well as the technology advancement aspect also can obtain a bigger development .The mold technology has gathered the machinery, the electron, chemistry, optics, the material, the computer, the precise monitor and the information network and so on many disciplines, is a comprehensive nature multi-disciplinary systems engineering. The mold technology development tendency mainly is the mold product to larger-scale, preciser, more complex and a more economical direction develops, the mold product technical content unceasingly enhances, the mold manufacture cycle unceasingly reduces, the mold production faces the information, is not having the chart, is fine, the automated direction develops, the mold enterprise to the technical integration, the equipment excellent, is producing approves the brand, the management information, the management internationalization direction develops. Our country mold profession still will have to enhance from now on the general character technology had :(1) to establish in the CAD/CAE platform the advanced mold design technology, enhances modernization which the mold designed, information, intellectualization, standardized level .(2) establishes in the CAM/CAPP foundation the advanced mold processing technology and the advanced manufacture technology unifies, raises the automated level and the production efficiency which the mold processes .(3) the mold production enterprises information management technology. For example PDM (product data management), ERP (enterprise resource management), MIS (mold manufacture management information system) and information network technology the and so on INTERMET platform application, the promotion and the development .(4) are high speed, Gao Jing, the compound mold processing technology research and the application. For example the ultra fine ramming mold manufacture technology, the precise plastic and the compression casting mold manufacture technology and so on .(5) enhances the mold production efficiency, reduces the cost and reduces the mold production cycle each kind of fast economical mold manufacture technology .(6) the advanced manufacture technology application. For example hot technology and so on flow channel technology, gas auxiliary technology, hypothesized technology, nanotechnology, rapid scanning technology, reversion project, parallel project in the mold research, the development, the processing process application .(7) the raw material the simulation technology which forms in the mold .(8) the advanced mold processing and the appropriation equipment research and the development .(9) the mold and the mold standard letter, the important auxiliary standardized technology .(10) the mold and its the product examination technology.(11) high quality, the new mold material research and the development and its the correct application .(12) the mold production enterprises modern management technology Mold profession in 十15 period needs to solve the key essential technology should be the mold information, the digitized technology and precise, ultra fine, high speed, the highly effective manufacture technology aspect breakthrough Along with the national economy total quantity and the industry product technology unceasing development, all the various trades and occupations to the mold demand quantity more and more big, the specification more and more is also high.Although mold type many, but its development should be with emphasis both can meet the massive needs, and has the comparatively high-tech content, specially at present domestic still could not be self-sufficient, needs the massive imports the mold and can represent the development direction large-scale, precise, is complex, the long life mold. The mold standard letter type, the quantity, the level, the production a and so on have the significant influence to the entire mold profession development. Therefore, some important mold standard letters also must the prioritize, moreover its development speed should quickly to the mold development speed, like this be able unceasingly to raise our country mold standardization level, thus improves the mold quality, reduces the mold production cycle, reduces the cost. Because our country mold product holds the bigger price superiority in the international market, therefore regarding the exportation prospect good mold product also should take key develops. According to the above required quantity big, the technical content is high, represents the development direction, the export prospect good principle choice prioritize product, moreover chooses the product to have at present to have the certain technology base, belongs has the condition, has the product which the possibility develops .According to 十15 the mold profession development plan, 十15 the period mold product development mainly has following several kind of the automobile cover mold (1) ramming mold to occupy the mold total quantity dish with emphasis above 40%. Automobile cover mold mainly for automobile necessary, also includes for the agriculture with the vehicle, the project machinery and the farm machinery necessary cover mold, it has the very big representation in the ramming mold, the mold mostly is large and middle scale, structure complex, the specification is high. For the passenger vehicle necessary cover mold, the request is in particular higher, may represent the ramming mold the level. This kind of mold our country had the certain technology base, already for middle-grade passenger vehicle necessary, but the level is not high, the ability is insufficient, at present satisfying rate only has one about the half.
