草坪砖塑料模具设计及加工的动画显示
摘 要
由于塑料具有许多金属和其它非金属所无法比拟的优点, 所以近年来发展尤为迅速。在现代工业和日用产品中，越来越多的塑料制品代替了以往的多类产品，而模具作为塑件的成型技术也得到了迅速发展。
本次毕业设计就是在Pro/ENGINEER平台上对速度表主动齿轮进行的注射模具设计。塑料注射模是模具中的一种，也是当今市场最常用、最具发展前景的模具之一。在设计过程中，通过了解和掌握塑料尼龙及速度表主动齿轮塑料模具设计的有关知识，主要完成注射塑料模具的成型部分、浇注系统、脱模机构、模体等部分的设计，并利用功能强大的CAD软件Pro/ENGINEER进行三维造型及模具工过程的动画设计。
通过本次设计，不仅掌握了注射模具的基本设计过程和设计要领，并了解了塑料的基本成型工艺，以及软件Pro/ENGINEER的实体建模、装配建模、制图基础、工过程动画设计等各个环节的基本操作规则及运用方法，从而可以利用软件Pro/ENGINEER或其它三维设计软件完成模具的整体设计。

The lawn brick plastics molding tool design and Animation of Worker's Course
Abstract
Because the plastics have many advantages that the metals and other nonmetals with for can't compare to, it developed quickly these yeas. In the modern industry and the articles for daily use, more and more plastic products replaced many products of former, and the mould as the technique of mould for plastic also got the quick development.
The design project for graduation is on the Pro/ENGINEER platform to design the injection mould for Initiative gear wheel of the autometer. It is one of the molds, and also in nowadays market is the most in common used, most having the developing foreground of the mold insides the injection mould for plastics. In the design process, through the understanding and mastering the plastics Nylon and Initiative gear wheel of the autometer, primarily complete to the plastics mould of type part, injection system, , and design the system for the plastics taking off and the frame of mold the etc. And make use of the Pro/ENGINEER which is one of the CAD software with mighty functions to accomplish 3D shapes and Animation of worker's course.
After finishing this design, we not only control the basic process and the main points of the injection mould’s design, but also understood entity that the plastics's fundamental type craft, and the solid modeling, the assembly and the engineering drawing in Pro/ENGINEER, Animation of worker's course, graphics the foundation to the basic operation rule and application method of the each link. Finally, we can make use of the Pro ENGINEER and other 3D soft ware to complete the mould overall does.
Keywords：The injection mould for plastics; Plastics ;Pro/ENGINEER
