集美大学课程设计说明书题目：三星手机后盖注射模具设计姓名：林杰专业：材料成型及控制工程班级：1211班学号：201221136011指导老师：陈怀民樊晓红李波王沁峰胡志超张燕红2016年1月11日三星手机后盖注射模具设计[摘要]注射成型是热塑性塑料成型的主要方法之一，可以一次成型形状复杂的塑件。本次课程设计对三星手机后盖注射模具进行了设计，对塑件结构进行了工艺分析，确定ABS为塑件的材料。采用一模两腔的结构，并根据模具的锁模力选择了注射机，再用注射量、注射压力进行了校核。对浇注系统进行了设计，采用端面进胶的侧浇口，并对流道进行了布置，根据注塑机的型号确定了定位圈与浇口套的尺寸与形式。选择了Futaba公司的标准模架，对顶出装置与冷却系统进行了设计。对成型零件进行了设计，确定了模仁的大小并在Pro/ENGINEER进行开模。进行侧抽结构的设计，确定导柱的倾斜角、长度，并对滑块的结构进行设计。最后在EMX下生成三维图，导入AutoCAD对装配图和零件图进行绘制。[关键词]注射模具；手机后盖；ABS；侧抽机构；EMXDesignofThePlasticMoldofTheBackCoverForSamsungMobileAbstractInjectionmoldingisoneofthemostsignificantmeasuresinthermoplasticsforming,whichcanproducecomplexpartsdirectly.DuringthisMoldCourseDesign,adesignoftheplasticmoldofthebackcoverforSamsungmobilehasbeencarriedout.ThestructureoftheproducthasbeenanalyzedaccordingtothemanufacturingprocessandABSwaschooseasthematerialofthebackcover.Therewouldbetwocavitiesinamoldforincreaseefficiency.Basedonclampingforce,themodelofinjectionmoldingmachinehasbeenchoose,andthecalculationofinjectionvolumeandinjectionpressurehasbeendonetomakesurethemachinecouldworkproperly.Usingsidegateasthewayoffillingcavityandplacingrunnerinproperway,thedesignofgatingsystemhasbeencompleted.Themodelofinjectionmoldingmachinedeterminedthetypeoflocatingringandspruebush.ThemoldbaseofFutabacompanyhasbeenchooseandthedesignofejectsystemandcoolingsystemhavebeendone.Tocreatemoldingparts,thesizeofmoldcorehasbeendecideandtheappearanceofcavityandcorehasbeengeneratedbyPro/ENGINEER.Afterdecidingtheslantangleandlengthofanglepin,figureoutthestructureofslider,thedesignofsidecorepullingsystemhasbeencompleted.Finally,three-dimensionaldiagramhasbeengeneratedbyEMX,andthenithasbeenimportedtoAutoCADtocreateassemblydrawingsandpartdrawings.Keywords:injectionmolding;backcoverofmobile;ABS;sidecorepullingsystem;EMX目录引言···································11零件成形工艺分析···························21.1零件概述·····························21.2零件材料分析···························21.3零件结构工艺性分析························31.3.1零件的壁厚·························31.3.2零件的拔模斜度·······················41.4零件生产要求···························42确定型腔的数目····························53模具胀型力的计算，选择注射设备····················73.1模具胀型力的计算·························73.2注射设备的选择··························73.3注射机有关工艺参数的校核·····················83.3.1最大注射量的校核······················83.3.2注射压力的校核·······················84确定型腔布置·····························94.1型腔按短边并排布置·····...
