毕业设计题目：密码器外壳注塑模设计学生：刘文武学号：20110310206院（系）：职业教育师范学院专业：材料成型及控制工程指导教师：张昌松2015年5月28日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精密塑件。本设计是微型密码器外壳塑料模具的设计，对零件结构进行了工艺分析，采用ABS作为塑件的材料。采用双分型面，根据模具的型腔数目以及最大注塑量、注射压力、锁模力、模具的安装尺寸等因素选择了注射机，选择成型零部件的尺寸；采用两板式模具小型模具，潜伏式浇口；利用直导柱导向，斜顶顶出，完成侧抽和顶出、脱模，并对模具的材料进行了选择，如此设计出的结构可确保模具工作运行可靠。对模具结构与注射机的匹配进行了校核。最后用UG绘制出模具三维图形及AutoCAD绘制了一套模具装配图和零件图。关键词：密码器，注塑模，模具设计，两板式AbstractInjectionmoldingisoneofthemainmethodofthermoplasticplasticmolding,canbeacomplicatedshapeofprecisionplasticformingparts.Thisdesignisthemicropasswordshellplasticmolddesignandanalysisofpartsstructuretechnology,adoptABSasthematerialofplasticparts.Withdoublepartingsurface,accordingtothemoldcavitynumber,andthemaximuminjectionvolume,injectionpressureandclampingforce,theinstallationofthemouldsizefactorssuchastheinjectionmachinechoice,choosethesizeofthemoldingparts;Usetwoplatemoldsmallmold,latenttypegate;USESthestraightguidepillarguidance,obliquebumps,completesidesmokeandejection,parting,andtheselectionismadetothemoldmaterial,suchastructurearedesigned,whichcanensurethemoldreliableoperation.Onthemoldstructureandinjectionmachinematchingcheck.FinallyusingUGtomapthemold3dgraphicsandAutoCADdrawingasetofmoldassemblydrawingandpartdrawing.Keywords:Password,injectionmold,molddesign,twoplate目录摘要.....................................................................................................................................................IAbstract..................................................................................................................................................II1绪论...............................................................................................................................................11.1模具工业的概况.......................................................................................................................11.2我国的塑料模具工业技术现状................................................................................................11.3我国塑料模具工业和技术今后的主要发展方向....................................................................32制件分析...........................................................................................................................................52.1成型工艺分析...........................................................................................................................52.2密码器零部件（ABS）的成型特性与工艺参数......................................................................52.2.1ABS塑料主要的性能指标..............................................................................................52.2.2ABS的注射成型工艺参数..............................................................................................63注塑设备的选择...............................................................................................................................83.1估算塑件体积...................................................................................
