模具设计课程实训四通管

课程设计（论文）题目：四通管的塑料注射模设计（英文）：DesignofFourwaypipeplasticinjectionmold院别：专业：姓名：学号：指导教师：日期：四通管的塑料注射模设计摘要本次设计是针对建筑工程或给排水工程所用的塑料四通管的设计。其表面的精度要求不高，模具设计上采用了直接浇口、开合模定位装置、液压抽芯机构、推管推出机构等措施。实现高效、质量高、成本低的产品设计、生产原则。设计中使我学到了很多知识，跟课堂上的学习很不同。设计过程中出现了问题，如何去解决，这将对我以后的工作和生活都很有帮助。本设计是通过翻阅一些产品设计和塑料模具设计有关的参考资料和文献，结合绘图软Pro/EngineerWildfire4.0、AutoCAD2008和Moldflow6.1、Mastercam9.1对四通管件的产品和模具的初步设计。关键词：四通管件；注射模具；侧抽芯机构DesignofFourwaypipeplasticinjectionmoldAbstractThedesignisinaccordancewithforthefourwaypipeusedfortheconstructionengineering、watersupplyanddrainageengineering.Itssurfaceaccuracyisnothigh,diedesignusesthedirectgate,openingandclosingthemoldpositioningdevice,hydraulicpressuresidecore-pullingmechanism,ejectormechanismandmeasures.Thepurposeistoachievehighefficiency,highquality,lowcostproductsdesign,andproductionprinciple.TheknowledgeIlearnedfromthedesignisverydifferentfromwhichIlearnedfromtheclass.Therearemanyproblemsduringthedesignprocess,howtosolvethem,whichIlearnedwillbeveryhelpfulformyfutureworkandlife.Duringthedesign,Ireadanumberofbooksaboutproductdesignandthereferencedataofplasticmolddesign,combiningwiththedesigningsoftwarePro/EngineerWildfire4,AutoCAD2008andmoldflow6.1,mastercam9.1pipeproductsandmolddesigntoaccomplishthepreliminarydesignofthemouldKeywords:Fourpipe;Injectionmold;thesidecore-pullingmechanism目录2塑件分析..........................................................12.1零件二维图及PROE三维图........................................12.2塑件产品分析..................................................22.3塑件材料的选择................................................22.3.1UPVC材料.................................................22.3.2PE材料...................................................22.3.3PC材料...................................................33注射机的选择......................................................43.1运用PRO/E分析零件............................................43.2通过MOLDFLOW6.1对塑件进行分析..................................43.3选择注射机....................................................53.3.1注塑机分类.................................................53.3.2.校核注射机的最大注射容积..................................63.3.3.锁模力的校核..............................................63.3.4开模行程校核...............................................74塑件浇口分析和浇注系统的形成......................................84.1方案的设定....................................................84.1.1方案一①：.................................................84.1.2方案一②：................................错误!未定义书签。4.2.1方案二①..................................错误!未定义书签。4.2.2方案二②..................................错误!未定义书签。4.3.1方案三①..................................错误!未定义书签。4.3.2方案三②：.................................错误!未定义书签。4.4结论：........................................错误!未定义书签。4.5浇注系统的形式和浇口的设计....................................94.5.1主流道的设计...............................................94.5.2主流道衬套................................................104.5.3定位圈....................................................104.5.4主流道衬套的固定..........................................114.5.5分流道的设计..............................................114.5.6分流道的表面粗糙度........................................114.6浇口设计.....................................................124.6.1浇口位置的选择应遵循以下原则：............................124.6.2浇口类型的选择：..........................................124.7冷料穴的设计.................................................135模具设计的有关计算...............................................145.1塑件型腔径向尺寸计算.........................................145.2型腔深度计算.................................................155.3成型零件钢材的选用（型芯）...................................175.3.1成型零件的选用要求........................................175.3.2材料4Cr5MoSiV分析......................................186模架及机构的设计.................................................196.1模架的选择...................................................196.1.1注射机最大与最小模具厚度与模架的高度校核..................206.2排气系统的设计和温度调节系统设计.............................216.2.1排气系统..................................................216.2.2冷却系统的设计............................................216.3塑件分型面和侧向抽芯.........................................226.3.1总图......................................................226.3.2分型面的选择原则..........................................226.3.3侧向分型与抽芯机构的确定..................................236.4顶出系统和合模导向机构设计...................................246.4.1顶出系统设计..............................................246.4.2合模导向机构的设计........................................246.4.3导向结构的总体设计........................................246.4.4导柱设计..................................................256.5导柱孔与导套.................................................256.5.1导柱孔的基本要求..........................................256.5.2导套......................................................266.6复位杆的设计.................................................266.7脱模推出机构的设计...........................................276.8推杆设计.....................................................276.8.1推杆的设计................................................276.8.2推杆位置的选择............................................2
