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 c 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。关键词：模具；镁合金:汽车轮毂；挤压铸造；模具设计；低压铸造ABSTRACTThispapermainlyresearchonautomobilewheel.Basedonthegeneralprocessofproductdevelopment,thetechnicalrouteismadeincludingproductstructure,processschemeandmould.UsingthesoftwareofCAD,suchasthestructuredesignofautomobilehubwithperformanceanalysis,mouldmodelling,castingprocessdesign,etc.Chinaintroducedthealuminummoldwheelstatusquofirsttime,development(rendsandChina'sdevelopmentofnewtechnologiesdie,followedaroundthefamilycaraluminumwheeldesigntoolforthestructuralcharacteristicsofwheel,themoldcavitytodeterminethenumberofsurfaceaswellasfrommodeinstitutions.Themethodaboutmoldingprocessofmagnesiumalloywheelismultiple.Thewayofmanufacturingautomobilewheelwimsqueezecastingisnotripeonitsresearchstage.Thispapersummarizedmainpointsofthesqueezecastingmould,Checkthemanualmolddesign,moldchoicetodeterminethestructureofmoldsize,molddesigncompleted.AtthesametimemakefulluseofcomputergraphicssoftwaretodesignpartsusingPro/Esionalmodelingofpartsandcomponentstoachievethelhree-dimensionalassemblyandmolddesign.Throughthisdesign,theentiredesignprocessofthemoldwithabetterunderstanding.Keywords:Mold；MagnesiumAlloy；AutomobileWheel；SqueezeCasting；MoldDesigning；LowPessureCsting目录Abstract.....................................
