前言

随着各种性能优越的工程塑料不断开发，注塑工艺越来越多地被各个制造领域用以成型各种性能要求的制品。要高质量、经济地生产出注塑制品，必须综合考虑成型树脂、注塑模具及注塑机的问题，注塑模具的设计质量直接影响成型制品的生产效率、质量及成本。

注塑模具在注射制品成型中起着极其重要的作用，除了塑料制品的表面质量、成型精度完全由模具决定之外，塑料制品的内在质量、成型效率也受模具左右，所以如何高质量、简明、快捷、规范化地设计注塑模具，成为发挥注塑成型工艺的优越性，扩大注塑制品的首要问题。

传统的注塑模具设计，主要是依赖设计人员的经验，设计的速度、质量及可靠性的程度，因设计人员的经验而异。又因模具是单品或极少批量的产品，采用传统设计方法，每一张图纸都需要手工绘制，设计人员的工作强度大，设计工作难以达到规范化、标准化。目前世界上工业发达的国家和地区都已相继采用计算机技术进行注塑模具设计，其主要是采用计算机辅助设计即CAD及计算机辅助工程CAE。

我国模具工业从起步到飞跃发展，历经了半个多世纪，近几年来，我国模具技术有了很大发展，模具水平有了较大提高。大型、精密、复杂、高效和长寿命模具又上了新台阶。模具质量、模具寿命明显提高；模具交货期较前缩短。模具CAD/CAM/CAE技术相当广泛地得到应用，并开发出了自主版权的模具CAD/CAE软件。塑料模是应用最广泛的一类模具。近年来，我国塑料模有长足的进步。在制造技术方面，首先是采用CAD/CAM技术，用计算机造型、编程并由数控机床加工已是主要手段，CAE软件也得到应用。

摘要：首先对产品进行市场调查及工艺分析，定出可行的方案，然后详细介绍注塑模设计的人工及CAD流程，阐述了在Pro/Engineer环境下注塑模设计

的一般流程，对塑件进行CAE分析后，进入模具的结构设计及有关参数计

算，接着进行浇注系统及模具的有关键零部件设计，最后把关键零部件的

二维图和立体图，还有模具的装配图和爆炸图以图纸形式展现出来。
