摘要摘要模具是工业生产用的重要的工艺装备，在现代工业生产中，60%～90%的工业产品需要使用模具，模具工业以成为工业发展的基础，许多新产品的研制与开发很大程度上依赖于模具的生产，因此，研究和发展模具技术，提高模具水平，对促进国民经济的发展有着特别重要的意义。本论文主要论述了材料为ABS的小尺寸、一般精度的提带连接扣注射模的设计方法。论文首先介绍了塑料成型基础及塑料注射成型的工艺过程；其次通过对注塑加工方法及提带连接扣进行综合工艺分析，确定了提带连接扣注射模的设计方案，即该模具采用一模四腔、侧抽芯的设计方案。然后针对该方案进行了重点论述，主要包括侧抽芯的塑件及其注塑模的设计过程、注塑模主要零部件的设计要点等。其中注塑模主要设计的重点包括：侧抽芯设计、零件结构设计、模具分型面的选择、型腔数目的确定、浇注系统的设计、滑块的设计、注射机的强度校核等。最后论文针对提带连接扣塑件的成型工艺方法以及其模具采用侧抽芯生产的可行性进行了论证。关键词：提带连接扣；注塑模；侧抽芯；分型面；注射机。AbstractAbstractMoldisanimportantsetupinmodernindustry.Inmanufacturingindustry,60～90percentofproductsutilizemold.Moldingindustryhasbeenaessentialfactorofindustrydevelopment.Anumberofnewproducts’developmentsconsiderablydependonmoldmaking.Therefore,itissignificantfornationaleconomytoresearchandimprovemoldtechnology.Thedissertationintroducesthedesignofinjectionplasticmoldforthebuttonlinkedbelt.themoldmadebyABSissmallsizeandcommonprecision.Firstly,Thedissertationmainlyexplainsthedesigningprocessofthemold.Secondly,Thedissertationanalysesshapingcraftanddevisestheshapingstrategy.Themoldadoptsonemoldandfour-cavitiesandsidepull.Thedissertationgivesfullyanalysistothemakingprocess.Thirdly,thedissertationfocusesontheanalysisofthedesignofinjectionplasticmoldsforthebuttonlinkedbelt,including:sidepulldesign;structuralpartdesign;decisionofpartingplane;assuranceofcavitynumber;designofgatingsystem;designofslidingblock;strengthverification,etc.Lastly,thedissertationdemonstratesthefeasibilityofthedesign.KeyWords：thebuttonlinkedbeltinjectionplasticmoldsidepullPartedplaneinjectionmachine-I-目录目录摘要.........................................................................................................................IAbstract...........................................................................................................................I绪论...........................................................................................................................-1-1塑料基础知识............................................................................................................41.1树脂...................................................................................................................41.2高分子聚合物...................................................................................................41.3聚合物分子结构...............................................................................................41.4塑料的组成.......................................................................................................42塑料注射成型工艺....................................................................................................62.1注射成型原理与成型工艺过程........................................................................62.2侧向抽芯注射成型模具结构简介....................................................................83提带连接扣注射模的设计.....................................
