I摘要本次设计是插座面板注塑模设计。塑件确定采用聚乙烯材料,该材料具有绝缘性好、强度高、价格低廉可用于双孔、三孔插座。该设计使用了Pro/E软件对插座面板进行三维造型,即利用参数化实体造型的方法,为更加高速、快捷的造型、生产提供了一种切实可行的办法。设计以单分型面注塑模,型腔采用的是一模两腔注射。该塑件采用侧浇口注射和组合式型腔设置,推出形式为两杆推出机构完成塑件推出。我在这次设计中借阅了大量的文献,还通过互联网查找了相关资料,设计过程比较完整。关键词单分型面注射模插座聚乙烯IIAbstractThedesignistheSocketFacegraduatedfromtheinjectionmolddesign.Mouldadocumentadoptpolyethylenematerial,thatmaterialtohaveinsulationregards,intensityheight,cheapbeusedfor,threesocketstwopriceholeforsure.TheproductandmoldoftheSocketFacewas3DdesignedbyPro/Esoftware.Makeuseofparameterizationentitymodelmethod,givebirthtoachildformorehighspeed,rapidmodel,havingprovidedonekindofapracticalmethod.ModeldesigningthatmarkoftypeproducesplasticarticlesbyinjectionmouldingfacetofacewithShan,thatthetypecavityadoptsisonemodeltwocavitiesinjection.Shouldmouldapieceadoptobliquetonesrunninggateinjectionandthedyadiccombinationtypecavityinterpose,debutaformfortwopolesdebutorganizationbeingcompletedmouldingapiecedebut.Iborrowthedocumenthavingreviewedagreatquantityincurrentdesign,havesoughttherelevancedatabyInternet,havedesignedprocesscomparativelyentirely.KeywordssingletypeofinjectionmoldssocketPE徐州工程学院毕业设计论文I目录1绪论.............................................................................................................................................11.1前言.......................................................................................................................................11.2塑料工业简介......................................................................................................................11.3我国塑料模现状..................................................................................................................21.4塑料模发展趋势..................................................................................................................32塑件的分析.................................................................................................................................42.1塑料材料的选择分析.......................................................................................................42.2塑件的尺寸、精度...............................................................................................................42.3塑件的几何形状...................................................................................................................42.3.1脱模斜度........................................................................................................................42.3.2脱模斜度方向................................................................................................................52.3.3塑件的壁厚....................................................................................................................52.3.4塑件的加强筋................................................................................................................52.3.5圆角................................................................................................................................52.3.6塑件的支承面................................................................................................................52.3.7塑件上的孔....................................................................................................................53注射设备的选择.........................................................................................................................73.1有关制品的计算...................................................................................................................73.2注射机型号的确定...............................................................................................................84分型面的选择.............................................................................................................................95塑料件的工艺尺寸的计算.......................................................................................................116模具型腔壁厚的计算...............................................................................................................147普通浇注系统设计...................................................................................................................167.1浇注系统的作用.................................................................................................................167.2设计的基本原则.................................................................................................................167.3普通浇注系统的组成与设计............................................................................................167.3.1主流道..........................................................................................................................167.3.2分流道..........................................................................................................................187.3.3.冷料穴和拉料杆设计.................................................................................................197.3.4浇口设计......................................................................................................................208排气系统的设计............................................
