VE瓶盖模具设计及其型腔仿真加工摘要：注塑模具是现在所有塑料模具中使用最广的模具，能够成型复杂的高精度的塑料制品。本课题是对VE瓶盖模具设计并分析加工工艺。本模具考虑到年产量、工厂的设备及塑件的精度要求，选择一模四腔结构。以瓶盖主体的面作为分型面,使制品强制脱模。流道采用带环形冷料穴，脱模时方便将主流道凝料和塑件带出，确保熔融塑料几乎能同时到达每个型腔的进料口。为了使动、定模能够准确地动作,导向定位机构利用导柱与导套的配合。顶出机构是推杆推出的一次脱出机构。考虑到零件的位置关系,冷却水道采用循环式分布，以便冷却均匀、快速。采用ProE来实现VE瓶盖三维设计及模具成型零件设计，分析制件的成型质量和完成分型面的设计，再采用CIMATRION来实现其数控仿真的加工，并在产品设计及模具装配过程中，辅助以必要的理论计算，将数字化设计与理论计算结合起来，可以大大缩短产品研发周期、模具设计周期，提高产品设计及模具设计的准确性、产品成型质量，降低产品研发、模具设计成本。在设计过程中制定了合理的工艺方案，满足了大批量生产要求。同时，还编制了详细的工艺文件来保证模具的顺利加工及制品的生产。通过合理的设计，本模具满足生产与应用的要求。关键词：注塑模具；加工工艺分析；Pro/E。塑料瓶盖模具设计及其型腔仿真加工1TheDesignandSimulationProcessingofMoldforVECapsAbstract：Atpresent,injectionmoldingistheplasticsmouldthathasbeingusedmostextensively,itcanmoldthecomplexandhighaccurateplasticproduct.TheSubjectisaboutthedesignofVEcapsandsimulationprocessing.Consideringtheannualoutput,theequipmentofthefactoryandtherequirementofprecisionoftheplasticproduct,fourcavitiesinamould.ThemiddlehorizontalsurfaceofthegoodswasTocapthemaincircleandsecuritybetweenthesurfaceasatypeface,sothatmandatoryStrippingproducts.Therunnerisdesignedtobebalancedandsymmetricaldistribution,ensurethatmeltingplasticcouldreacheachcavitysgatealmost.SuspensionandPositioningmechanismusematchedguidepillarandguidesleevetomakemovablemould,fixedmouldtoworkaccurately.Theknockoutsusesonceejectingmechanismthatlifterpushesout.Bytherelationofthepositionofeachpart,coolingchannelsaredesignedtostraightchannelstocooleffectively,quickly.WithPro/Engineer,MoldFlowtoimplementthree-dimensionaldesignandmoldvolumedesignofVEcaps,andshapingqualityofpartwasanalyzedandthepartinglinewasdesignedbyPro/Engineer,thenutilizedCIMATRIONtoaccomplishtheassemblageofthemoldwiththeassistanceofessentialtheorycalculatemixedwithfiguredesign.Itwouldnotonlyshortenthecycleofproductresearchandmolddesign,andimprovetheprecisenessandtheproductshapingquality,butalsolowerthecostoftheresearch.Havingmadetherationalcraftschemeinthedesignprocess,soithasmettherequirementofproducinginenormousquantities.Moreover,italsopreparedadetaileddocumenttoensurethattheprocessforthesmoothprocessingofmoldandapparelproduction.Throughtheratio
