摘要
目前塑料在实现“以塑代钢”方面起着不可忽视的作用，它正以其物美价廉的特征渗透到国民经济的各个领域。工程塑料制品的速度增长率为每年10%，然而在工程塑料中70%—80%以上的制品是采用注塑成型加工。如今塑料制品广泛应用于广泛应用于电子、机械、汽车、航天、家电、玩具等各个行业。因此也使注塑模具的设计与制造带来了繁荣的景象。在模具设计中，Pro/E软件以它强大的实体建模功能和结构分析功能扮演着不可或缺的角色。
本文简要概述了CAD技术在国内外的发展状况，介绍了CAD在模具工业中的使用和发展情况,介绍了在我国研究和发展模具CAD技术的必要性和迫切性, 介绍了Pro/E软件的一些模块及其功能，介绍模具与注射机的关系等，并图文并茂介绍了利用Pro/E软件进行模具设计的整个过程。涵盖主题包括：模具型腔设计，浇注系统设计，脱模机构设计，温度调节系统设计， 开模模拟等知识面。
在英文翻译中，我将对国内资料没有详细介绍的温度调节系统作了介绍。

Abstract
At present the plastic is playing the noticeable role in realizing "by plastic instead of steel" aspect. It is famous as its excellent in Quality and reason able in price characteristic and infiltrate to each domain of national economy. Engineering plastics go up by the ratio of 10% each year, however 70% - 80% above product isuses in the engineering plastics casts takes shape the processing. Now the plastic product widely applies in the domain of the electron, the machinery, the automobile, astronautics, the electrical appliances, the toy and so on. Therefore the design and the manufacture about the mold has broad foreground In mold design, Pro/E software is playing the indispensable role in its formidableentity modelling function and the structure analysis function.
This article has briefly outlined the development condition of the CAD technology in the domestic and foreign , introduced the use and development situation of the CAD in the mold industry ,introduced the necessity and urgency that develop and study mold CAD technology in our country, introduced some modules and its the function of the Pro/E software , introduced the relationship of the mold and the injection machine and introduced the entire processuses which realize the mold designs using the Pro/ E software abundantly and elegantly. The design subject includes: the design of mold cavity, the design of pours system, the design of drawing of patterns organization, the control system design about temperature, simulation of opening mold and so on.
In English translation, I have made the introduction to temperature control system that the domestic material not detailed introduction.
