摘要摘要吹塑成型是热塑性塑料制件的一种主要成形方法。吹塑成形可成形各种形状的塑料制件。它的特点是成形周期短，能一次成形外形复杂，尺寸较为精密，不带嵌件的塑料制件，且生产率比较高，易于实现自动化生产，所以广泛用于塑料制件的生产。近年来，PET吹塑瓶以其质量轻、强度高、透明、无毒等优点被大量用于饮料包装，特别是碳酸性饮料的包装，于是提出了PET树脂中空吹塑模具设计。该设计方案首先分析了PET瓶的几何结构和瓶坯的吹塑成型工艺，模具工作部分的温度控制等；然后提出了中空吹塑模具的结构，并阐述其工作原理。该模具结构设计合理，操作方便，能满足使用要求。关键词：PET树脂；瓶坯；吹塑模；冷却水道。IABSTRACTABSTRACTTheblowinginjectionformationisthethermoplasticworkpieceonemainformedmethod.Theinjectionformingmayformeachkindofshapetheplasticworkpiece.Itscharacteristicsistotakeshapeperiodshort,cantakeshapetheshapecomplicationsonce,sizenicety,taketheplasticssystempieceofhavethepiece,andtherateofproductionishigh,beingeasytocarryouttheautomationproduction,sousedfortheproductionoftheplasticssystempieceextensively.Inrecentyears,withitsqualitymouldhightrength,ransparent,non-toxicadvantages,PETbottleswereusedtothebeveragepackaging,especiallythecarbonatedrink.ThenPETresinforblowmoldingmoulddesign.ThedesignschemeisfirstlyanalyzedthegeometricalstructureofPETbottleofbottlepreformandblowmoldingprocess.Mouldworkoftemperaturecontrolpartsetc.Thenitputsforwardforblowmoldingmouldstructure.,anditsworkingprinciple.Themouldstructurereasonabledesign,convenientoperation,cansatisfytherequirementsofoperation.Keywords:PETresin;bottlereform;blowingmold;coolingchannels.II目录目录摘要................................................................................................................................................IABSTRACT......................................................................................................................................II第一章简介...........................................................................................................................11.1概述...............................................................................................................................11.2吹塑制品的应用.............................................................................................................21.3选题的依据和意义.....................................................................................................41.4本课题目前发展状况.....................................................................................................41.5本课题在国外的发展现状.............................................................................................51.6塑料注塑模具的地位和未来的发展趋势.....................................................................6第二章吹塑制件设计.........................................................................................................92.1吹塑件的功能和性能要求.........................................................................................92.2材料及其性能...........................................................................................................102.3吹塑制件的几何结构设计.......................................................................................122.3.1容积....................................................................................................................122.3.2.外形..............
