11、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

12、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。2.

21、刚起步，大多还处于试用和动画游戏阶段；在应用CAM技术制造模具方面，一是缺乏先进适用的制造装备，二是现有的工艺设备（包括近10多年来引进的先进设备）或因计算机制式（IBM微机及其兼容机、HP工作站等）不同，或因字节差异、运算速度差异、抗电磁干扰能力差异等，联网率较低，只有5%左右的模具制造设备近年来才开展这项工作；在应用CAPP技术进行工艺规划方面，基本上处于空白状态，需要进行大量的标准化基础工作；在模具共性工艺技术，如模具快速成型技术、抛光技术、电铸成型技术、表面处理技术等方面的CAD/CAM技术应用在我国才刚起步。计算机辅助技术的软件开发，尚处于较低水平，需要知识和经验的积累。我国大部分模

35、具，所采用的三维数字化模型能方便地用于产品结构的CAE分析、模具可制造性评价和数控加工、成形过程模拟及信息的管理与共享。如Pro/ENGINEER、UG和CATIA等软件具备参数化、基于特征、全相关等特点，从而使模具并行工程成为可能。另外，Cimatran公司的Moldexpert，Delcam公司的Ps-mold及日立造船的Space-E/mold均是3D专业注塑模设计软件，可进行交互式3D型腔、型芯设计、模架配置及典型结构设计。澳大利亚Moldflow公司的三维真实感流动模拟软件MoldflowAdvisers已经受到用户广泛的好评和应用。国内有华中理工大学研制的同类软件HSC3D4.5F

36、及郑州工业大学的Z-mold软件。面向制造、基于知识的智能化功能是衡量模具软件先进性和实用性的重要标志之一。如Cimatron公司的注塑模专家软件能根据脱模方向自动产生分型线和分型面，生成与制品相对应的型芯和型腔，实现模架零件的全相关，自动产生材料明细表和供NC加工的钻孔表格，并能进行智能化加工参数设定、加工结果校验等。 （3）模具软件应用的网络化趋势 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。4. Heat Treatment of DieTraditional die and

37、mould design, mainly by experience or semiexperience，is isolated from manufacturing process. Before the design is finalized，the scheme of die and mould is usually modified time and again，thus some disadvantages come into being, such as long development period, high cost and uncertain practical effec

Therefore more and more advanced technologies and innovations have been applied, for example, concurrent engineering, agile manufacturing virtual man

39、ufacturing, collaborative design, etc.Heat treatment of die and mould is as important as design, manufacture and assembly because it has a vital effect on manufacture，assembly and service lifeDesign and manufacture of die and mould have progressed rapidly，but heat treatment lagged seriously behind t

40、hemAs die and mould industry develops，heat treatment must ensure die and mould there are good state of manufacture，assembly and wearresistant properties by request. Impertinent heat treatment can influence die and mould manufacturing such as overhard andsoft and assemblyTraditionally the heat treatm

42、ily the designers rarely understood the service environment and designing thought. These divergences will impact the progress of die and mould to a great extent. Accordingly，if the process design of heat treatment is considered in the early designing stage，the aims of shortening development period，r

45、elopment，and the systemic and profound research was performed4.模具的热处理模具设计主要是依照自身实践经验或依照部分实践经验，而不是制造工艺。在设计完成之前，模具方案通常要被一次又一次的改进，于是有些缺点便出现，例如开发时期长，成本高和实际效果不明显。由于对精确性、使用寿命、开发期和费用的严格要求，先进的模具要求设计和制造得十分完善。因此越来越先进的技术和创新方法被应用其中，例如并行工程、敏捷制造业、虚拟制造业、协同合作设计等。模具的热处理与模具设计，制造和装配同样重要。因为它对模具的制造装配和使用寿命又及其重要的影响。模具设计与制

46、造发展十分迅速，但是热处理发展却严重滞后它们。随着模具工业的发展，热处理必须保证模具有良好的制造装配和磨损耐热性能。不切实际的热处理将导致模具材料过硬或过软，同时影响模具装配性能。传统的热处理工艺是按照设计师提出的方法和特性制作出来的。这样会使模具设计师和热处理工艺师意见产生分歧，而模具设计师却不能充分地了解热处理工艺和材料的性能，相反热处理工艺师却很少了解模具的使用环境和设计思路。这些分歧将在很大程度上影响模具的发展。因此，如果把热处理工艺设计放在设计阶段之前，则缩短开发周期，减少花费和保证质量等目标将会被考虑，而且从串行到并行的发展模式也将会实现。并行工程是以计算机集成系统作为载体，在开始

47、以后，每个阶段和因素都被看作如制造、热处理、性能等等，以避免出现错误。并行模式已经摒除了串行模式的缺陷，由此带来了一场对串行模式的革命。在当前的工作中，热处理被集成到了模具开发的并行环境中，同时也正在进行这种系统性和深入性的研究。5.
