摘要Pro/Engineer（以下简称Pro/E）是一款三维建模软件，它是一套由设计至生产的机械自动化软件，是新一代的产品造型系统，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，在工业设计和机械设计等方面有很好的可操作性。Pro/Engineer还提供了目前所能达到的最全面、集成最紧密的产品开发环境。同时本课题还用到了ExpertMoldbaseExtension（以下简称EMX）,模具专家系统扩展，它是Pro/E软件的模具设计外挂。它是Pro/e的一个自动分模工具，利用该模具库，家用电器、玩具和汽车零件制造商们将可在模具开发及制造方面有效地控制成本。本课题《鼠标及其模具设计》就是基于Pro/E的产品开发设计，采用Pro/E软件对鼠标上盖制品及模具进行了三维造型，采用Pro/E的数值模拟技术和经验设计计算相结合的方法优化设计,同时仿真了塑料熔体在型腔内的充模流动以及冷却分析过程。关键字：Pro/EEMX鼠标模具1AbstractPro/Engineer(hereinafterreferredtoasPro/E)isa3Dmodelingsoftware,itisadesigntotheproductionofmechanicalautomationsoftware,anextgenerationofproductmodelingsystem,usingparametricsolidmodelingapproach,inordertostrengthenitshighspeedandtheshortcutofmodeling,productionprovidesaviable,inindustrialdesignandmechanicaldesign,andsohaveverygoodoperability.Pro/Engineeralsooffersthemostcomprehensiveandintegratedtogetherproductdevelopmentenvironment.ThisissueofthemouseandmoulddevelopmentisbasedonPro/E'sproductdevelopmentanddesign.AtthesametimethissubjectalsousedtotheExpertMoldbaseExtension(hereinafterreferredtoastheEMX),dieexpertsystemextensions,itisPro/Esoftwarediedesignplug-in.ItisthePro/eapartingtool,usethestencillibrary,householdappliances,toys,andautomotivepartsmanufacturerswillmoulddevelopmentandmanufacturing,effectivelycontrollingcosts.UsingPro/Esoftwareonmouseovertheproductanddieforthree-dimensionalmodeling,useofPro/Eofnumericalsimulationandexperiencedesigncalculationmethodtooptimizethedesign,andsimulationplasticmeltinthecavityofmoldingandcoolinganalysisprocess.Keywords:Pro/EEMXmousedies2目录摘要.................................................................................................................0Abstract............................................................................................................1前言.................................................................................................................31.原料成型特征与工艺参数..........................................................................51.1产品的材料....................................................................................51.2ABS塑料主要的性能指标.............................................................51.3ABS的注射成型工艺参数.............................................................61.4ABS的成型特性.............................................................................61.5ABS的脱模斜度的推荐值及其他参数.........................................72.外形设计.....................................................................................................82.1底盖设计..........................................................................................82.2上盖设计..........................................................................................82.3支架设计........................................................................................252.4中键设计........................................................................................273.鼠标的装配...............................................................................................303.1装配底盖.......................................................................................303.2装配中键.......................................................................................303.3装配支架.......................................................................................313.4装配上盖.......................................................................................324.分解视图..................................................................................................334.1爆炸图简介...................................................................................334.2鼠标的爆炸图............................................................................335.鼠标模具设计...........................................................................................355.1模具的国内外现状及发展趋势....................................................355.2鼠标注塑模具的现状....................................................................365.3注塑件成型的工艺要求.................................................................375.3.1塑件几何形状方面的要求...................................................375.3.2塑件的尺寸精度要求..........................................................385.4注塑件设计要点............................................................................385.5注塑件缺陷及其原因....................................................................385.6分型面设计....................................................................................39总结..............................................................................................................40致谢..............................................................................................................41参考文献.......................................................................................................423前言此次设计的鼠标（上盖）主要是三键光电式鼠标，如何设计3键鼠标，首先创建鼠标上盖和鼠标左、中、右三个按键，最后在Pro/ENGINEERWildfire的装配模块中完成鼠标上盖和三个按键的装配。主要是鼠标上盖及三个按键的造型方法。在比例中，将用到多种复杂的造型方法，重点是将在主体造型过程中用到变截面扫描特征、剖面圆顶及唇特征等高级特征。在讨论注塑模设计之前，我们有必要先对国内外的塑料模具工业的状况、塑料模具工业的发展方向有一个较清晰的了解，这也就使我们对本课题的意义有所了解。首先要对模具有一个整体的认识。模具是机械、汽车、电子、通讯、家电等工业产品
