毕业设计论文某种手机外壳塑胶模具设计PLASTICMOLDDESIGNOFMOBILEPHONE学生姓名学院名称专业名称指导教师20年5月27日徐州工程学院毕业设计论文I摘要本次的毕业设计是手机外壳的注塑模的设计,该模具有重量轻、耐腐蚀老化、使用寿命长,制作方便、价格低廉等特点本课题采用Pro/E软件和CAD对手机外壳及模具进行了三维造型和模架选取,采用Pro/E的数值模拟技术和经验设计计算相结合的方法优化设计。该设计通过对多种相似塑件的模具结构参考,设计的是ABS塑件,采用的是一模双腔注射。该产品采用侧浇口注射和组合是式型腔设置。依据产品的数量和塑料的工艺性能确定了以单分型面注塑模的方式进行设计。。由于塑件的工艺性能要求注塑模中有冷却系统,因此在模具设计中也进行了设计。本次的设计中参考了大量的文献,还在互联网上查找资料,设计过程比较完整关键词模具手机外壳CAD软件ABS徐州工程学院毕业设计论文IIAbstractThedesignisthecellphonecasegraduatedfromtheinjectionmolddesign,themoldislightweight,corrosionresistantaging,insulation,productionconvenience,lowprices,andothercharacteristics.Theproductandmoldofthecellphonecasewas3DdesignedandmoldbasebyPro/EsoftwareandCAD.AnoptimizeddesignwasmadebynumericalsimulationtechniquesofPro/Eandexperience.Accordingtotheproductquantityandtheplastichandicraftfunctionhaveascertainedthattobeallottedatypeonlyproducingplasticarticlesbyinjectionmouldingfacetoface,themodelwaycarriesoutdesign.weusetheABSastherawmaterial.Asthepiecesofplasticinjectionmoldofperformancerequirementsinthecoolingsystem,inthemolddesignhavealsocarriedoutinthedesign.Thereferenceinthedesignofalargenumberofdocuments,alsoontheInternettofindinformation,morecomprehensivedesignprocess.KeywordsmoldcellphonecaseCADsoftwareABS徐州工程学院毕业设计论文I目录摘要..................................................................................................................................................IAbstract..........................................................................................................................................II1绪论..............................................................................................................................................11.1注塑模具基本概念...............................................................................................................11.1.1塑料制件........................................................................................................................11.1.2本文研究的外壳模型...................................................................................................31.2注塑模结构的组成及分类...................................................................................................32塑件的成型工艺分析..................................................................................................................52.1ABS的注塑工艺条件.............................................................................................................52.1零件结构分析.......................................................................................................................83注射设备的选择.........................................................................................................................93.1有关塑件的计算...................................................................................................................93.2注塑机型号的确定...............................................................................................................93.3注塑机及型腔数量的校核.................................................................................................103.4注塑机及参数量的校核.....................................................................................................103.4.1注射量的校核..............................................................................................................103.4.2注塑模结构的组成及分类..........................................................................................103.5塑件在分型面上的投影面积与锁模力校核.....................................................................113.6最大注射压力校核.............................................................................................................113.6.1模具与注射机安装部分的校核..................................................................................123.6.2开模行程校核..............................................................................................................124分型面的选择...........................................................................................................................134.1分型面的形式.....................................................................................................................134.1分型面的设计原则.............................................................................................................135浇注系统的形式和浇口的设计................................................................................................155.1主流道的设计.....................................................................................................................155.1.1主流道的尺寸..............................................................................................................155.1.2主流道衬套的形式......................................................................................................165.2主流道冷料井的设计........................................................................................................185.3分流道冷料井设计.............................................................................................................185.4分流道的设计................................................................
