摘要

 近年來，塑料產(chǎn)品和塑料模具得到了飛速的發(fā)展，應(yīng)用也越來越廣泛。本文為冰箱抽屜設(shè)計了一副注射模。設(shè)計過程主要利用了Moldflow、UG和AutoCad工具軟件，充分利用計算機輔助的優(yōu)越性實現(xiàn)了設(shè)計方案。作者首先Moldflow進行了CAE分析，得到一系列的計算結(jié)果,接著分析了塑件的結(jié)構(gòu)工藝性，選擇了單分型面模具，采用滑塊裝置，并利用AutoCAD及燕秀工具箱完成了模具二維圖紙的設(shè)計。然后，利用了UG的三維建模功能將模具二維圖紙進行三維造型。最后利用AutoCAD修改該副模具的總體裝配圖和繪制一些重要零件的零件圖。所設(shè)計的模具結(jié)構(gòu)簡單，機構(gòu)運行可靠，所繪制的模具圖紙對實際生產(chǎn)具有指導意義。

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.
