过滤水嘴注射模设计论文[带图纸].doc

哈尔滨工业大学华德应用技术学院毕业设计(论文)I摘要本文简要介绍了模具行业现在的情况和未来的发展趋势。提到了限制模具发展的因素。基于塑料过滤水嘴注塑工艺分析及模具设计,介绍了注射成型的基本原理,特别是双分型面注射模具的结构与工作原理,对注塑产品提出了基本的设计原则详细介绍了注射模具浇注系统和顶出系统的设计过程,并对模具强度要求做了说明。以塑料过滤水嘴模具为主线,综合了成型工艺分析,模具结构设计,最后到模具零件的加工方法,模具总的装配等一系列模具生产的所有过程。该注射模最显著的特征是避免了传统的脱模方式。该模具结构设计简单可靠,加工装配方便。在查阅参考文献和对塑件进行工艺性分析的基础上,确定了模具设计的整体方案。并对塑料模具的设计参数进行了必要的计算,根据计算结果选用了注射机。最后利用AutoCAD和Pro/e软件对塑件过滤水嘴注射模总装配图及主要零部件进行了设计,完成了模具的整体结构设计。关键词注射模顶出系统分型面。哈尔滨工业大学华德应用技术学院毕业设计(论文)IIAbstractInthispaper,basedonthemouthofthebottleCypriotinjectionmolddesignandprocessanalysis,Thisdesignintroducedtheinjectiontakesshapethebasicprinciple,speciallysingleisdividedtheprofiletoinjectthemoldthestructureandtheprincipleofwork,tocasttheproducttoproposethebasicprincipleofdesign,tothemouthofthebottleCypriotDiemainline,theIntegratedProcessanalysis,molddesignofthestructure,thelasttodiepartsmachiningmethods,thedieassemblyandaseriesofmoldallprocess.Thefirstpartbrieflyintroducedmouldindustryandthecurrentsituationinthefuture.Mentionedthefactorsrestrictingthedevelopmentofmold.Thesecondpartofaprocessoftheworkpieceanalysis,molddesignpackage.Accordingtoplasticmolddesignmanualandtherelevantexperienceoftheformulanecessary,accordingtoresultsoftheinjectionmachineused.Furthercompletionofthestandardandnonstandardchoiceofthedesign.PartIIIcompletionoftheoverallstructureofthemolddesign.KeywordsInjectionMoldDesignProcesstechniquePullingstructur哈尔滨工业大学华德应用技术学院毕业设计(论文)III目录摘要......................................................................................................................IAbstract................................................................................................................II第1章绪论.........................................................................................................11.1模具工业在国民经济中的地位..............................................................11.2各种模具的分类......................................................................................21.3我国模具工业的现状...............................................................................31.4我国模具技术的现状及发展趋势..........................................................41.5国外模具工业的发展情况......................................................................51.6毕业设计的要求及主要内容..................................................................51.6.1设计要求...........................................................................................51.6.2设计的主要内容...............................................................................5第2章注射件材料的分析...............................................................................72.1塑料制品的设计分析..............................................................................72.2塑件体积和质量......................................................................................82.3材料特性..................................................................................................82.3.1ABS的特点........................................................................................82.3.2ABS的成形特性................................................................................82.3.3ABS的成型工艺参数........................................................................92.4脱模斜度..................................................................................................112.5塑件的壁厚..............................................................................................112.6本章小结................................................................................................12第3章模具设计.............................................................................................133.1型腔数量的确定与配置........................................................................133.1.1型腔数量的确定.............................................................................133.1.2分型面的确定.................................................................................143.1.3型腔的配置.....................................................................................143.2注射机的选用........................................................................................153.2.1类型选择.........................................................................................153.2.2注塑机基本参数.............................................................................173.2.3塑件的的参数计算.........................................................................173.3模架的确定............................................................................................20哈尔滨工业大学华德应用技术学院毕业设计(论文)IV3.3.1标准模架简介.................................................................................203.3.2标准模架的选用..............................................................................203.4成型零部件的工作尺寸计算................................................................213.4.1工作尺寸分类和规定.....................................................................213.4.2影响制品尺寸误差的因素.............................................................223.4.3凹模尺寸计算.................................................................................243.4.4凸模尺寸计算.....................................
