毕业设计论文基于PRO/E的某款吸尘器万向轮注射模具设计AINJECTIONPLASTICMOULDDESIGNOFRELEASECARDANWHELLOFONEKINDOFDUSTCOLLECTORBASEDONPRO/EI摘要在现代工业中,模具工业已经成为制造业的基础,这一观点随着全球制造业向我国转移的过程中被越来越多的有识之士所意识到。而在模具行业中塑料模又是其重中之重,此种模具占模具行业值的50以上,我国的塑料成型模具设计,制作技术比较晚,整体水平还比较低。目前单型腔、简单型腔的模具达70以上,占主导地位。本论文介绍了吸尘器万向轮注射模具的设计过程。从万向轮的测绘,PRO/E的三维建模,分型面的确定,型腔数目和布局的确定,注射机选择,浇注系统设计,冷却系统设计,模板及其标准件的选用,脱模机构的设计,成型部件的设计等一一进行了详细的介绍。塑件的中心圆柱内有四个小的加强筋,难加工,是本设计的难点,需要用到型芯镶件。通过本设计,可以对注射模具有一个初步的认识,模架的结构及其动作原理都有了一定的了解。注射模是安装在注射机上的,因此在设计注射模时应该对注射机的有关技术规范进行必要的了解,以便设计出符合要求的模具,同时选定合适的注射机型号。关键词注射模模具设计PRO/E模架IIAbstractInmodernindustry,dieindustryhasbecomethebasisofmanufacturing,thisviewastheprocessoftheglobalmanufacturingtransfertoChinabeingawaredbymoreandmoreinsightfulpeople.Theplasticmouldistoppriorityinthedieindustry,suchmouldofthedieindustryproductionvalueover50percent.Chinasplasticmolddesign,productiontechnologyrelativelylate,theoveralllevelisstillrelativelylow.Atpresent,singlecavityandsimplecavityofthemoldmorethan70percent,itsdominated.Thispaperintroducedthedesignprocessofcardenwhellofdustcollector.Introductionfromthecardenwhellsmodeling,determinedofpartingface,determinedofthecavitysnumberandlayout,choicedofinjection,designedofpouringsystem,designedofcoolingsystem,choicedoffollowboardandstandardunit,designedofmouldemptier,designedofformingpartandsoon.Plasticscenterhasfourlitterdabber,difficultprocessing,designbecomedifficulty,needusingcoreinserts.Throughthisdesign,Icanhaveapreliminaryunderstandingoftheinjectionmold,thediecarriersframeandactionprinciple.UnderstandingtheselectedofdiecarrierandinjectionmachineneedthroughtocalculationthevarioussizeandchecktheStrength.KeywordsPlasticinjectionmouldMoulddesignPRO/EDiecarrierI目录1绪论.............................................................................................................................................11.1模具在加工工业中的地位.................................................................................................11.2模具的发展趋势.................................................................................................................11.3万向轮设计的基本要求.....................................................................................................22产品技术要求和工艺分析.........................................................................................................32.1产品技术要求.....................................................................................................................32.1.1万向轮的测绘..............................................................................................................32.1.2万向轮的三维建模......................................................................................................32.1.3脱模斜度......................................................................................................................52.1.4万向轮设计的技术要求..............................................................................................52.2塑件的工艺分析.................................................................................................................52.2.1塑件结构的工艺性......................................................................................................52.2.2塑件工艺性分析..........................................................................................................52.3塑件材质工艺性.................................................................................................................52.4成型工艺性.........................................................................................................................73确定模具的结构形式.................................................................................................................93.1分型面位置的确定..............................................................................................................93.2成型方案的列出...............................................................................................................103.2.1方案一........................................................................................................................103.2.2方案二........................................................................................................................113.3成型方案的选定...............................................................................................................113.4型腔数目和排列方式的确定...........................................................................................123.4.1型腔数目的确定........................................................................................................123.4.2腔排列方式的确定....................................................................................................123.5注塑机的选择...................................................................................................................133.5.1注塑机的结构类型....................................................................................................133.5.2ABS塑料注塑工艺分析.............................................................................................143.6注射成型原理及工艺..............................
