摘 要
 塑料產(chǎn)品和塑料模具工業(yè)在當(dāng)前國(guó)民經(jīng)濟(jì)中占據(jù)重要地位。本文為手機(jī)殼體設(shè)計(jì)了一副塑料注射模具。設(shè)計(jì)過(guò)程中主要利用UG、Cimantron和AutoCAD工具軟件，充分發(fā)揮計(jì)算機(jī)輔助設(shè)計(jì)的優(yōu)越性，實(shí)現(xiàn)了模具設(shè)計(jì)設(shè)想。作者首先分析塑件的結(jié)構(gòu)工藝性，選擇了單分型面模具，并利用UG Moldwizard模塊完成了成型零部件的建模。然后，根據(jù)設(shè)計(jì)計(jì)算結(jié)果，在UG中完成了模具的推出機(jī)構(gòu)、導(dǎo)向機(jī)構(gòu)和結(jié)構(gòu)零部件等的建模。然后利用AutoCAD繪制了該副模具的總體裝配圖和重要零件的零件圖。最后利用Cimantron軟件的CAM對(duì)型腔、型芯進(jìn)行數(shù)控加工編程和模擬加工，通過(guò)Cimantron軟件來(lái)出刀路軌跡。本設(shè)計(jì)的模具結(jié)構(gòu)簡(jiǎn)單，機(jī)構(gòu)運(yùn)行可靠，所繪制的模具圖紙對(duì)實(shí)際生產(chǎn)具有指導(dǎo)意義。

Abstract
 The plastic products and plastic mold industry are of great importance of in national economy. The injection mold design of a Mobilephone’s cover was completed in the dissertation. This article has designed a plastic injection mold for the washing machine’s cover. The software tools of UG、Cimantron and AutoCAD are mainly used in the design process，and the advantages of computer-aided design programs was fully utilized to achieve the design scheme. Firstly, the author chose a single parting surface for the mould according to the analysis of the plastic part craft, and finished mold parts modeling with the UG Moldwizard. Then based on the design results, all the other components assemblies were modeled in the UG, such as the modeling of ejection parts, guide parts ,and other structure parts and so on. Finally. The assembly drawing and some of the important parts drawings were made in the AutoCAD. Finally, the CAM software of Cimantron to made the cavity, the core for NC programming and simulation of processing, through Cimantron software tool path to a trajectory. 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.
