摘要光阴似梭，大学两年的学习一晃而过，为具体的检验这两年来的学习效果，综合检测理论在实际应用中的能力，除了平时的考试、实验测试外，更重要的是理论联系实际，即此次设计的课题为闹钟后盖的注塑模具。本次毕业设计课题来源于生活，应用广泛，但成型难度大，模具结构较为复杂，对模具学习人员是一个很好的考验。它能加强对塑料模具成型原理的理解，同时锻炼对塑料成型模具的设计和制造能力。本次设计以注射闹钟后盖模具为主线，综合了成型工艺分析，模具结构设计，最后到模具零件的加工方法，模具总的装配等一系列模具生产的所有过程。能很好的学习致用的效果。在设计该模具的同时总结了以往模具设计的一般方法、步骤，模具设计中常用的公式、数据、模具结构及零部件。把以前学过的基础课程融汇到综合应用本次设计当中来，所谓学以致用。在设计中除使用传统方法外，同时引用了CAD、UG等技术，使用Office软件，力求达到减小劳动强度，提高工作效率的目的。本次设计中得到了王老师的指点。同时也非常感谢琴岛学院各位老师的精心教诲。由于实际经验和理论技术有限，设计的错误和不足之处在所难免，希望各位老师批评指证。关键词：注塑模具、CAD、设计、装配AbstractUniversityoftimelikeshuttle,handguns,andtwoyearsofstudyforaspecifictestofthelearningeffectinthepasttwoyears,comprehensivedetectiontheoryinthepracticalapplicationability,inadditiontotheusualtest,thetest,moreimportantistointegratetheorywithpractice,namelythedesignoftheprojectforthealarmclockbackcoverinjectionmold.Thegraduationdesigntaskoriginatesfromlife,wideapplication,butmoldingdifficult,diestructureisrelativelycomplex,isagoodtestforthemouldstaff.Itcanstrengthentheunderstandingofplasticmoldingprinciple,andexerciseonplasticmoldingmolddesignandmanufacturingcapabilities.Alarmclockbackcoverthisdesigntoinjectionmouldsasthemainline,basedontheanalysisofthemoldingprocess,moldstructuredesign,finallytomoldpartsprocessingmethods,moldallofthegeneralassemblyandaseriesofmoldproductionprocess.Canbeaverygoodlearningtool.Inthedesignofthemouldatthesametimesummarizesthegeneralmethodandstepsofmolddesign,moulddesignofcommonlyusedformula,data,diestructureandparts.Thepreviouslylearnedbasiccoursetointegratedapplicationofthedesign,theso-calledknowledge.Besidesusingtraditionalmethodsinthedesign,atthesametime,referencestheCAD,UGandothertechnology,theuseofOfficesoftware,makeseveryefforttodecreasethelaborintensity,improveworkefficiency.Obtainedinthedesignofthekingoftheteacher'sadvice.Atthesametimealsothankyouverymuchjeanislandcollegeteacherscarefullytaught.Becauseofpracticalexperienceandtheoreticaltechnologyco.,LTD.,thedesignerrorsandshortcomingisinevitable,hopeeverybodytheteachercriticismagainst.Keywords:Injectionmold,CADdesign,assembly目录摘要............................................................................................................IAbstract............................................................................................................II1绪论................................................................................................11.1模具在加工工业的地位...................................................................11.2模具的发展的趋势.........................................................................11.3设计在学习模具制造中的作用...........................................22塑件的工艺分析...........................................................................32.1塑件成型工艺分析...................................................................................32.2闹钟后盖原料...
