本科毕业设计论文题目爱普生打印机支架注射模设计系别机电信息系专业机械设计制造及其自动化班级学生学号指导教师2013年5月I爱普生打印机支架注射模设计摘要塑料模具是一门新兴工业,是随着石油工业发展应运而生的,作为现代四大工业基础之一,越来越广泛地在各行各业应用。本课题设计了打印机支架的整个生产过程。通过对塑件的工艺性分析,确定了一模两腔的基本方案,选择了侧浇口进料,注射机采用海天800XB型号。采用了斜导柱抽芯机构和斜滑块抽芯机构实现了塑件两侧孔的成型,使用了推杆和推板推出机构实现了模具的推出脱模过程。选用了水冷冷却系统,保证了塑件的生产效率和质量。本次设计通过绘制CAD二维图和Pro/E三维图完整的表现出整个模具结构,并通过设计说明书简明的表达出整个模具的生产过程,从而为以后同类零件生产做出良好基础。关键词爱普生打印机支架注射模设计侧浇口斜导柱抽芯机构推杆推出机构IIDesignofInjectionMoldforEpsonPrinterSupportAbstractPlasticmoldisaburgeoningindustry,withtheemergeasthetimesrequirethedevelopmentoftheoilindustry,asoneofthefourmodernindustrialbase,moreandmorewidelyappliedinallwalksoflife.Thissubjectdesignstheprintersupportofthewholeproductionprocess.Throughanalyzingthetechnologyofplasticparts,determinethebasicschemeofonemoduleandtwocavities,chosethesidespruefeeding,injectionmachineadoptHaitian800xbmodel.Theslantedguidepillarcorepullingmechanismandtheinclinedslideblockcorepullingmechanismrealizesthemoldingholesatbothsides,usethepushrodandthemechanismtoachievetheintroductionofthemoldreleaseprocess.Choosethewatercoolingsystem,guaranteetheproductionefficiencyandqualityofplasticparts.Thisdesignbydrawing2DCADmapandPro/Ethreedimensionalmapshowthecompletethemoldstructure,andthroughtheexpressionofdesignspecificationsconciseproductionprocessofthemold,soastomakeagoodfoundationforfuturesimilarpartsproduction.KeywordsEpsonprintersupportInjectionmoulddesignThesidegateInclinedguidepillarcorepullingmechanismPuttingoutinstitutionsIII目录1绪论......................................................................................................................11.1塑料简介.........................................................................................................11.2注塑模具的发展.............................................................................................11.3设计意义.........................................................................................................22塑料材料分析....................................................................................................32.1塑件材料的选择和塑料材料的基本特性.....................................................32.2塑件材料主要用途.........................................................................................32.3ABS注射工艺性.............................................................................................43塑件的工艺分析...............................................................................................53.1塑件的结构设计.............................................................................................53.2塑件尺寸及精度.............................................................................................73.3塑件表面粗糙度.............................................................................................73.4塑件的体积和质量.........................................................................................74注射成型工艺方案及模具结构的分析和确定.......................................84.1注射成型工艺过程分析.................................................................................84.2浇口种类的确定.............................................................................................94.3型腔数目的确定及型腔布局确定.................................................................94.4注射机的选择和校核.....................................................................................94.4.1注射量的校核......................................................................................104.4.2塑件在分型面上的投影面积与锁模力的校核.................................114.4.3模具与注射机安装模具部分相关尺寸校核.....................................114.5分型面的设计...............................................................................................124.6模架的选用...................................................................................................135浇注系统的设计.............................................................................................155.1浇注系统的设计...........................................................................................155.2浇注系统组成...............................................................................................155.3确定浇注系统的原则...................................................................................155.4主流道的设计...............................................................................................155.5分流道的设计................................................................................................175.6浇口的设计...................................................................................................175.7冷料穴的设计...............................................................................................185.8拉料杆的设计...............................................................................................18IV5.9排气结构设计...............................................................................................196成型零部件的设计........................................................................................206.1注射模成型零部件的设计...........................................................................206.2成型零部件结构设计..........................................................
