摘要针对对讲机后盖进行了注塑模具设计。通过对塑件进行工艺的分析和比较,最终设计出一副注塑模。该课题从产品结构工艺性，具体模具结构出发，对注塑机的选择及有关参数的校核、模具的分型面、浇注系统、模具成型部分的结构、推出系统、冷却系统进行了设计。同时运用三维pro/E制图软件绘制该模具，与平面图相比更具立体感。关键词：注塑模具；浇注系统；冷却系统；校核AbstractThistopicismainlyforradioshellmolddesign,plasticpartsthroughtheprocessofanalysisandcomparisontothefinaldesignaninjectionmold.Processfromtheproductstructureonthesubjectof,specificmoldstructuretothesub-surfaceofthemold,pouringsystem,themoldformingpartofthestructure,launchsystems,coolingsystems,injectionmoldingmachineofchoiceandtheparametersofthecalibration,aredetaileddesign.Atthesametimedrawingzhemoldsusetothree-dimensionalmappingprogramofpro/E,thiscomputergraphicssystemhastheimpastocomparedtotheplainviewdrawing.Keywords：injectionmold；systemofgating；systemofcooling；checking.目录摘要.............................................................IAbstract...........................................................II第1章绪论.......................................................11.1模具工业的应用概况........................................11.2我国塑料模具工业的发展概况................................2第2章方案选择..........................................................42.1注射模的组成与分类........................................42.1.1注射模的组成.........................................42.1.2注射模的分类.........................................52.2塑件成型工艺分析..........................................52.2.1注射模的设计方法与研究现状...........................52.2.2塑件分析.............................................62.2.3制品材料的成形特性与工艺分析.........................82.3注射成型机的选择.........................................102.3.1注射量的计算........................................102.3.2浇注系统凝料体积的初步估算..........................102.3.3注射机的选择........................................102.4分型面设计................................................112.4.1分型面作用、形式和设计原则..........................112.4.2分型面的确定........................................122.5型腔设计.................................................142.5.1型腔数目的确定......................................142.5.2型腔排列形式的确定..................................152.5.3型腔壁厚尺寸的确定...................................152.6模具结构形式的设计.......................................152.7模具材料的选用...........................................18第3章部件的设计计算............................................193.1浇注系统设计.............................................193.1.1浇注系统的设计原则...................................193.1.2主流道的设计........................................193.1.3分流道的设计........................................213.1.4浇口设计............................................233.1.5冷料穴与拉料杆设计..................................243.2成型零件工作尺寸的计算...................................253.2.1定模板及其支撑板....................................253.2.2动模板及其支撑板....................................263.2.3垫块................................................273.2.4导向机构............................................283.2.5侧向抽芯机构：......................................283.3推出机构的...
