1毕业设计(论文)正文题目应用PRO/E设计修正带上盖注射模具专业机械设计制造及其自动化姓名学号指导教师职称2010年5月20日II应用PRO/E设计修正带上盖注射模具摘要：通过对市场现有的修正带上盖塑件的设计分析，设计出该塑件的模具。在整个模具设计过程中，涉及到了塑件的结构设计、注塑机的选择和一些重要工艺参数的校核、型腔数目和布局模式的确定，并详细叙述了模具设计中浇注系统的设计、成型零件和零部件的设计和冷却系统的设计。在模具设计过程中，采用了Pro/ENGINEER、EMX4.1等设计分析软件，采用这些软件进行设计分析，优化了设计的参数和缩短了设计时间，提高了设计效率。通过整个模具设计，本人已经能够熟练地使用当前常用的设计分析软件，学会了根据计算或者依据经验选择一些参数,增加了对注塑模具的了解。关键词：修正带上盖;模具设计;一模两腔;Pro/e;EMX4.1┊┊┊┊┊┊┊┊┊┊┊┊┊装┊┊┊┊┊订┊┊┊┊┊线┊┊┊┊┊┊┊┊┊┊┊┊┊IIIInjectionMoldDesignofAmendmenttoBringCaponPro/eAbstract：Throughtheamendmentputonthemarketcovertheexistingplasticpartsdesignanalysis,designoftheplasticparts.Inthemolddesignprocess,involvingthestructuraldesignofplasticparts,injectionmoldingmachineofchoiceandsomeimportantparametersofthecalibration,thecavitytodeterminethenumberanddistributionpatterns,anddescribedindetailinthecastingmolddesignandsystemdesign,moldingpartsandcomponentsdesignandcoolingsystem.Inthemolddesignprocess,usingPro/ENGINEER,EMX4.1andotherdesignanalysissoftware,thesoftwareusedtodesignanalysisandoptimizationofdesignparametersandreducedesigntimeandimprovedesignefficiency.Throughtheentiremolddesign,Ihadbeenabletoskillfullyusethecurrentpopulardesignanalysissoftware,learningexperiencesbasedonthecalculatedorselectsomeparameterstoincreasetheunderstandingofplasticinjectionmolds.Keywords：Amendmentstobringcover;Molddesign;Atwo-cavitymold;Pro/e;EMX4.1┊┊┊┊┊┊┊┊┊┊┊┊┊装┊┊┊┊┊订┊┊┊┊┊线┊┊┊┊┊┊┊┊┊┊┊┊┊IV目录1绪论.....................................................................11.1模具发展现状及发展方向............................................................................................11.1.1我国注塑模具的发展现状.................................................................................11.1.2我国注塑模具的发展方向.................................................................................31.2本次设计项目概述........................................................................................................31.2.1本课题选题的意义.............................................................................................31.2.2设计的主要内容.................................................................................................41.2.3设计的具体要求.................................................................................................42塑件的形状及结构设计.....................................................52.1塑件模型建立................................................................................................................52.2塑件材料的选择............................................................................................................52.3塑件的体积和质量........................................................................................................72.4塑件结构分析................................................................................................................83成型腔数的确定和注射机的选择.............................................93.1成型腔数的确定............................................................................................................93.2注射机的确定................................................................................................................93.2.1注射量的计算.....................................................................................................93.2.2锁模力（F）的计算...........................................................................................93.2.3注射机技术参数确定.........................................................................................93.2.4注塑机的参数校核...........................................................................................104浇注系统设计............................................................124.1浇注系统的作用..........................................................................................................124.2浇注系统的组成..........................................................................................................124.2.1主流道及冷料井的设计...................................................................................124.2.2分流道设计.......................................................................................................124.2.3浇口设计...........................................................................................................135成型零件及零部件的结构设计.............................................145.1分型面设计..................................................................................................................145.1.1分型面的设计原则...........................................................................................14┊┊┊┊┊┊┊┊┊┊┊┊┊装┊┊┊┊┊订┊┊┊┊┊线┊┊┊┊┊┊┊┊┊┊┊┊┊V5.1.2分型面的确定...................................................................................................145.2型腔的布局..................................................................................................................155.3凹模与凸模的结构设计..............................................................................................155.4成型零件工作尺寸设计..............................................................................................175.4.1影响塑件尺寸精度的因素..............................................................................
