摘 要
本文以汽车轮毂为研究对象,基于产品研究开发的一般流程,制定了产品结构设计、工艺方案设计、模具设计的技术路线。借助CAD等工具,对汽车轮毂结构设计与性能分析、并对模具造型、铸造工艺等进行了设计。
首先介绍了我国轮毂模具的现状、发展趋势及我国模具发展的新技术,其次围绕轿车轮毂模具进行设计,针对轮毂的结构特点,确定模具的型腔数目、分型面以及脱模机构。汽车轮毂的成型工艺方法较多,以挤压铸造生产轮毂的工艺方法现今多处于研究阶段。本文根据挤压铸造的工艺特点,对汽车轮毂挤压铸造模具设计进行了分析总结,并对模具型腔进行了结构设计,查阅模具设计手册,完成模具的总体设计。同时充分利用计算机绘图软件对零件进行设计, 利用Pro/E对零件进行三维造型, 并实现零件的三维装配和模具设计。通过本次设计,对模具整个设计过程有了较好的了解。

ABSTRACT
This paper mainly research on automobile wheel.Based on the general process of
product development,the technical route is made including product structure,process
scheme and mould.Using the software of CAD, such as the structure design of automobile
hub with performance analysis, mould modelling, casting process design, etc.
China introduced the aluminum mold wheel status quo first time, development trends
and China's development of new technologies die, followed aroundthe family car aluminum
wheel design tool for the structural characteristics of wheel, the mold cavity to determine
the number of surface as well as from mode institutions. The method about molding process
of magnesium alloy wheel is multiple.The way ofmanufacturing automobile wheel wim
squeeze casting is not ripe on its research stage.Thispaper summarized main points of the
squeeze casting mould,Check the manual mold design, mold choice to determine the
structure of mold size, mold designcompleted. At the same time make full use of computer
graphics software to design parts using Pro / E sional modeling of parts and components to
achieve thethree-dimensional assembly and mold design, Through this design, the entire
design process of the mold with a better understanding.
Key words: Mold;Magnesium Alloy;Automobile Wheel;Squeeze Casting;Mold
