矿泉水饮料瓶盖注射模具及成型零件加工工艺设计[摘要]本设计是对给定的材料为PP小尺寸，一般精度的矿泉水饮料瓶盖塑件进行模具设计。在综合研究了经济性、零件的成型工艺以及复杂性等诸多因素的基础上进行成型与工艺的分析与计算。文中还对注塑模具成型零件和其他相关零件的选择原则及选择方法进行了说明。期间借鉴了与塑料模具有关的文献再加上翻阅各种指导书籍，并通过大量的计算以确定模具的结构和尺寸，还在指导老师的悉心关怀和耐心指导下进行多次的反复修改，最终画出了装配图和零件图。最终确定矿泉水饮料瓶盖塑件的设计方案，主要包其注塑模的设计的过程、以及注塑模主要零部件的设计过程等。[关键词]注塑模具设计；模具结构；塑料瓶盖Abstract矿泉水饮料瓶盖注射模具及成型零件加工工艺设计ThisdesignisforagivenmaterialforPPsmallsize,thegeneralaccuracyofthechargershellplasticpartsformolddesign.Withinconsiderationoftheeconomy,partsofthemoldingtechnologyandcomplexity,andmanyotherfactorsinthemoldingprocessonthebasisoftheanalysisandcalculation.Italsoofinjectionmoldshapingparts,andotherrelatedpartstoillustratetheselectionprincipleandselectionmethod.Duringtorefertoalotofusefulinformationrelatedtoinjectionmoldandleafthroughallkindsofmanual,Andthroughcalculationtodeterminethemoldstructureandsize,Throughcontinuouscalculationandmodification,Andinguidingtheteacher'scarefulcareundertheguidanceandpatiencetoconstantlymodifyagainandagain,Finallythesuretodrawtheassemblydrawingandpartdrawing.Makesurethedesignofthechargershell,namelythemoldwithonemoduleandtwocavities,sidecore-pullingdesignscheme.Thenfocusesonthesolution,thispapermainlyincludesthesidecore-pullingofplasticpartsandinjectionmolddesignprocess,keypointsofinjectionmolddesignofmaincomponents.Keywords:Injectionmolddesign;Themoldstructure;Plasticbottlecap目录I矿泉水饮料瓶盖注射模具及成型零件加工工艺设计1概述.................................................................11.1课题来源...........................................................11.2课题的研究目的.....................................................12塑件结构工艺性分析...................................................32.1塑件造型...........................................................32.2塑件分析...........................................................42.2.1.塑件设计要求.....................................................42.2.2塑件结构分析.....................................................42.2.3脱模斜度.........................................................42.3塑件原材料分析.....................................................52.3.1PP材料特性......................................................52.3.2PP塑料主要用途..................................................52.3.3塑料材料成型性能.................................................52.3.4PP成型温度条件..................................................62.3.5.塑件的公差与表面质量............................................73拟定注塑模具结构.....................................................83.1分型面的确定.......................................................83.2型腔数目的确定.....................................................83.3拟选注塑机型号.....................................................93.3.1注射量的计算.....................................................93.3.2选择注塑机......................................................104注塑机相关参数的校核................................................104.1最大注射量的校核................................
