收音机前盖模具设计及其型腔仿真加工摘要：本课题是关于收音机前盖模具的设计，主要是收音机前盖注射成型模的结构设计和模具加工制造。前者包括分型面、型腔布置、浇注系统、排气系统、加热冷却系统、侧向抽芯机构、顶出机构、脱模机构以及主要零部件的设计。后者运用PRO/E进行三维造型设计并对注塑模模具进行装配，对收音机前盖模具定模板型腔的加工工艺进行了分析，并利用MASTERCAM软件进行了仿真加工，其切削过程直观，切削参数得以体现，不合理的参数可以改进，能最大限度地降低能源和材料消耗，提高加工效率。此注射模设计的结构特点是点浇口形式的双分型面的注射模，是侧向抽芯。经生产验证，该模具结构设计巧妙、操作方面、使用寿命长、塑件达到技术要求。关键词：模具设计：注塑模具；仿真加工；分型面本设计来自：完美毕业设计网HYPERLINK"http://www.bysj520.com"http://www.bysj520.com登陆网站联系客服远程截图或者远程控观看完整全套论文图纸设计客服QQ：8191040ThedesignoftheshellradiomouldAndthesimulationprocessingofthemoldcavityAbstract:Thistopicistodesigntheshellradiomold,whichincludesthestructuredesignmouldassistdesigningformanufacturing,andtheworkingprocessoftheinjectionmouldofthefrontcoveroftheshellofradiosetwereintroduced.Theformerinvolvepartingplane,cavitylayout,oldsystems,heatingcoolingsystems,thesidecorepullingmechanismstructure,propuptheorganization,drawingpatternsandthedesignprocessofthemainworkpieces.ThelaterusePRO/Etoconstructcarriesonthethreedimensionalmodelingandtoassembletheinjectionmould.Theprocessingcraftofthecavityoffixedplateofthebaseoftheshellradioareanalyzed,andthesimulationprocessarecarryoutwiththesoftwareofMASTERCAM，whichcanobservethegeometricfigureoftheprocessofcuttingveryvisually,themachineparametersuserssettinghavebeenfullyreflectedtoimprovetheunreasonableparameters,tominimizeconsumptionofenergyandmaterialsandtoimproveprocessingefficiency.Thestructurecharacteristicofthisinjectionmouldwasatwo-partingsurface,andwasasidecorepullingmechanism.Themouldwasprovedtobeacleverdesignbyproductionpractice,themouldcouldbeoperatedeasily,theservicelifeofthemouldwaslongorandtheplasticspartsproducedbythemouldcouldmeetthetechnicalrequirement.Keywords:molddesign;injectionmould;processingsimulation;partingplane；目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc201218883"1前言1HYPERLINK\l"_Toc201218884"1.1课题意义1HYPERLINK\l"_Toc201218885"1.2国内外发展现状1HYPERLINK\l"_Toc201218886"1.3设计前提及主要问题2HYPERLINK\l"_Toc201218887"1.4解决的主要问题和总体设计思路2
