中英文摘要

摘要：熟悉注射模具设计的一般流程，掌握注射模具的结构特点及设计计算方法，能用计算机编制相应的工程计算、分析和优化的程序并进行塑料产品三维造型及设计出其模具； 分析了塑料保护盖的结构特点及其成型材料的成型特征,介绍了如何设计该塑件的注射模具结构,着重介绍了斜导柱侧向分型与抽芯机构的设计计算；设计的全过程都在计算机上进行，所用的绘图软件有Solidworks2003和AutoCAD2004, 用Microsoft Word 2003完成了说明书的整理；对以前所学相关课程有了一个全面的了解，自己的知识和技能也得到了提高。

Abstract: Acquaint the general flow of injection mould design; Know the structure characteristics and the design calculating of injection mould; Can use computer to workout the process of which relevant the engineering calculate, engineering analyze and engineering optimize, and put up 3D sculpt to the plastic product, moreover design the mould of it. The structure

characteristics

and

the

forming

characteristics of the forming material of the protective cap were analyzed; How to design the structure of the injection mould were introduced; The design calculating of angle guide pillars of side parting and core-pulling system were stated in detail. The whole design process were going along in computer, the plot software had used are Solidworks2003 and AutoCAD2004, achieved the illuminate book on Microsoft Word
