注塑模具课程设计摘要本文以塑料勺为对象，详细介绍其注射模设计过程。设计中主要运用UG和AUTOCAD软件，根据制件的零件图进行零件的三维造型，并对该模型进行工艺分析，该塑件为壳体，浇注系统设计过程中，采取一模一腔侧浇口设计，并对成型零件进行了必要的计算和结构设计。采用龙记大水口标准模架，提高了设计效率。最后通过Autocad完成工程图的制作，设计中综合考虑了各方面的因素。关键词：塑料勺，注射模，UG，侧浇口InjectionmouldDesignABSTRACTThedesignofasetofblanking,punchingmold.throughaccesstoinformation,thefirstpartstotheprocessanalysis,throughprocessanalysisandcomparison,theuseofblanking,punchingprocess,throughtheblankingforce,thetoppiece,andintermsofdischargepowertodeterminethemodelpress.Furtheranalysisofthestampingdiesforprocessingtheapplicationtoselectthedesiredtypeofmolddesign.Themoldwillbedesignedtodrawuponthetypeofmoldpartsoftheworkexpressedinthedesignprocess.Keywords：Plasticspoon,Injectionmould,UG,Sidegate目录摘要....................................................................ⅠABSTRACT.............................................................Ⅱ1塑料成型工艺性分析....................................................11.1塑件分析....................................................................................................................11.2注射成型过程及工艺参数........................................................................................21.3PC的性能分析..........................................................................................................22拟定模具结构形式......................................................42.1分型面位置的确定....................................................................................................42.2确定型腔数量和排列方式........................................................................................42.3模具结构形式的确定................................................................................................53注射机型号的确定......................................................63.1所需注射量的计算....................................................................................................63.2注射机型号的选定....................................................................................................63.3型腔数量及注射机有关工艺参数校核....................................................................74浇注系统的形式和浇口的设计...........................................104.1主流道的设计..........................................................................................................104.2冷料穴的设计..........................................................................................................124.3浇口的设计..............................................................................................................124.4浇注系统的平衡......................................................................................................134.5浇注系统凝料体积的计算......................................................................................134.6浇注系统各截面流过熔体的体积计算..................................................................134.7普通浇注系统截面尺寸的计算与校核..................................................................145成型零件的结构设计和计算.............................................165.1定模部分的型芯与型腔.........................
