摘要本文详细地阐述了盖注射模具的设计过程。设计了注射模具中的各个系统，如浇注系统、导向与定位机构、侧向分型与抽芯机构，并对塑料材料性能进行了分析。根据塑件的产品数量要求，以及结构要求，该模具采用一模一腔。整个设计过程都是用CAD软件进行参数化设计，使整个模具设计过程简单明了。利用MPA软件进行模流分析，为模具设计和成型工艺的指定提供参照依据。使用CAD软件设计成型零件以及非标零件，从而进行全方面的参数化设计，即对模具进行分模、生成元件、装配、试模、开模等设计。调用标准模架以及标准件，从而完成模具的整体设计。直接指导生产。针对塑件的特点，本模具设计了侧抽芯滑块机构，也构成了本次模具设计的主要内容。关键词：注射模；参数化设计；侧抽芯和滑块；灯罩AbstractThispaperdescribesthedesignprocessoftheplasticinjectionmold.Designofthesystemintheinjectionmold,suchaspouringsystem,positioningmechanismforhorizontalorientation,core-pullingmechanism,analysisandplasticmaterialperformance.Accordingtothenumberofplasticproducts,andconstructionrequirements,theuseofthemoldcavity.ParameterizeddesignofCADsoftwareofthewholedesignprocess,thedesignprocessofthemouldissimple.FlowanalysisusingtheMPAsoftwaremodule,providingreferencesformolddesignandmoldingprocess.CADsoftwaredesignofmoldingparts,non-standardparts,sotheparametricdesign,inallaspectsofthatrelease,thegeneratingelement,assembly,testmode,molddesign.Callthestandardmouldbaseandstandardparts,soastocompletethewholedesignofthedie.Directproduction.Accordingtothecharacteristicsoftheplasticparts,molddesigncorepumpingmechanismontheside,andalsothemaincontentsofmolddesign.Keywords:injectionmold;parametricdesign;sidecorepullingtheslider;thelampshade.Keywords:injectionmould;parametricdesign;sidecorepullingandslidingblock;thelampshade目录摘要...........................................................I1前言...........................................................11.1模具行业发展的现状............................................11.2我国模具发展的现状............................................11.3参数化技术慨述................................................21.4选题目的以及意义.............................................32塑件成型工艺性分析............................................42.1摩托车尾灯罩二维图............................................42.2结构特征分析及成型工艺性分析..................................42.2.1结构特征分析................................................42.2.2成型工艺性分析..............................................42.2.3塑件材料的基本性能.........................................52.2.4塑料的成型收缩率...........................................52.2.5塑件材料的流动性...........................................53塑件成型工艺与设备.............................................63.1注塑成型工艺条件..............................................63.1.1温度.......................................................63.1.2压力.......................................................63.1.3时间.......................................................63.2注射机型号的确定.............................................83.2.1由公称注射量选择注射机.....................................83.2.2由锁模力选择注射机.........................................83.3型腔数量以及注射机有关工艺参数的校核.........................93.3.1型腔数量校核................................................93.3.4注射压力校核..............................................113.3.5安装尺寸校核..................
