摘要本文介绍了摩托车灯罩的模具设计过程。本设计对塑件在模具中的位置和分型面位置、选择浇注系统与排溢系统、成型零件的结构、合模导向机构、推出机构、侧向分型与抽芯机构、温度调节系统的设计方案做了充分的论证，并优化选取最合理的设计方案。对于塑件的侧孔处理，采取了斜导柱侧抽芯脱模，带有脱模斜度的孔，则利用塑件的脱模斜度替代侧抽芯，简化了模具结构。通过对型芯支承板和型腔板的计算，保证了模具的优良使用性，优化了模具的结构设计，使得模具结构紧凑。关键词：注射模；凸模；型芯；斜导柱侧抽芯；IAbstractThistextintroducedthemoulddesignprocessofthemotorcyclelampshade.Determiningtheplasticpartinmouldandselectionofthepartingline,thefeedandrunnersystemdesign,thecore/cavitycreationstructuredesign,theguidepinandguidebush,theplasticejectorstructure,externalundercutsandcoolingandejectionsystemdesigning,theyallbeanalyzedinthistext,andchoosethebestdesign.WiththeholeinthesideofproductdealwithAnglePin,iftheholeoblique,maketheuseoftilteddetrusionstraight,sothestructureofthemouldwillbesimplify.Bythecaculateofthecavityplateandbackingplate,makethemouldusedworkingorder,optimizedthemouldstructure,makethemouldstructurecompact.Keywords:injectionmould;Raisedmold；Core；LaterpartingCorewithAnglePin;II目录摘要............................................................................................................................................IAbstract.........................................................................................................................................II绪论.............................................................................................................................................1第一章塑件分析与模具材料和注射机的选取..........................................................................31.1塑件结构和技术要求的分析..........................................................................................31.1.1塑件结构分析.......................................................................................................31.1.2塑件零件图技术要求分析...................................................................................31.2塑料材料的成型特性与工艺参数..................................................................................31.2.1基本特性...............................................................................................................31.2.2主要用途...............................................................................................................41.2.3成型特点...............................................................................................................41.3模具材料的选取及热处理..............................................................................................41.4注射机的选取..................................................................................................................5第二章确定模具的结构方案....................................................................................................72.1确定塑件在模具中的位置和分型面位置......................................................................72.1.1型腔数目的确定...................................................................................................72.1.2塑件在模具中的位置和分型面的方案确定.......................................................72.2选择浇注系统与排溢系统的方式.................................
