摘要

 近年来，塑料产品和塑料模具得到了飞速的发展，应用也越来越广泛。本文为冰箱抽屉设计了一副注射模。设计过程主要利用了Moldflow、UG和AutoCad工具软件，充分利用计算机辅助的优越性实现了设计方案。作者首先Moldflow进行了CAE分析，得到一系列的计算结果,接着分析了塑件的结构工艺性，选择了单分型面模具，采用滑块装置，并利用AutoCAD及燕秀工具箱完成了模具二维图纸的设计。然后，利用了UG的三维建模功能将模具二维图纸进行三维造型。最后利用AutoCAD修改该副模具的总体装配图和绘制一些重要零件的零件图。所设计的模具结构简单，机构运行可靠，所绘制的模具图纸对实际生产具有指导意义。

Abstract
 In recent years, plastic products and plastic mold have developed rapidly, and their applications become more and more extensive. One injection mold for a refrigerator drawer was designed in this dissertation. The software tools of UG, AutoCAD and Moldflow are mainly used in the design process，and the advantages of computer-aided design programs were fully utilized to achieve the design scheme. Firstly, the author finished CAE analysis on parts by using Moldflow and obtained a series of calculated results, and analyzed the structure of the plastic part, and then chosed a single-mold surface and oblique-slip devices, and finished the drawings of the mold by AutoCAD and Yanxiu Tools at last.Then, parts modeling with the UG Moldwizard were finished. Finally,the author drew die deputy general assembly and some of the important parts with using the AutoCAD. As a whole the mould is simple in structure and good at working reliability. The design of this injection mold is of some significance for the fact production. In short, the mold design is simple and reliable, and the drawings of the mold are instructive for the actual production.
