插头壳体注塑模具设计论文[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摘要本论文基于插头壳体注塑工艺分析及模具设计,以插头壳体模具为主线,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。分析了圆形插头壳体的工艺特点,介绍了壳体注射模的整体结构及设计要点,研究了模具侧抽芯过程和侧抽芯机构的特点,提出了一种双侧抽芯机构,并设计了2种不同的侧芯方式,实现了顺利抽芯,解决了侧孔不易成型、侧抽机构难以设置的问题。关键词注射模侧抽芯机构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,tothemouthofthebottleCypriotDiemainline,theIntegratedProcessanalysis,molddesignofthestructure,thelasttodiepartsmachiningmethods,thedieassemblyandaseriesofmoldallprocess.Analysisthecraftcharacteristicsofthecircularplughullbody,introductionthehullbodyinjectwholestructureanddesignimportantpointofmold,researchthemoldingtoolsidetakeoutthecharacteristicsthatXinprocessandsidetakeoutXinorganization,putforwardakindofsidetotakeoutXinorganization,anddesign2kindsofdissimilarityofsideXinway,realizationsmoothtakeoutXin,solvedsideborenoteasymodel,thesidetakeoutorganizationhardconstitutionofproblem.KeywordsInjectionMoldThesidetakeoutXinorganizationCenttypenoodle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课题背景..............................................................................................11.1.1模具工业在国民经济中的地位...................................................11.1.2模具的分类和占有量...................................................................11.1.3我国模具工业的现状...................................................................11.1.4我国模具技术的现状及发展趋势...............................................11.1.5国外模具工业的发展情况...........................................................21.2毕业设计的主要研究目标及内容......................................................31.2.1设计目标.......................................................................................31.2.2设计的主要内容...........................................................................3第2章注塑件材料的工艺分析...................................................................42.1塑料制品的设计分析..........................................................................42.2塑件体积和质量..................................................................................62.3材料特性..............................................................................................62.3.1聚乙烯的使用性能.......................................................................62.3.2聚乙烯的加工特性.......................................................................62.3.3HDPE的成型条件.........................................................................72.4脱模斜度..............................................................................................92.5塑件的壁厚..........................................................................................92.6本章小结............................................................................................10第3章模具设计.........................................................................................113.1型腔数量的确定与配置....................................................................113.1.1型腔数量的确定.........................................................................113.1.2分型面的设计.............................................................................113.2注射机的选用....................................................................................123.2.1初选注射机的相关参数计算.....................................................123.2.2注射机参数校核.........................................................................143.3模架的确定........................................................................................15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.............................................................................153.3.2标准模架的选用..........................................................................163.4成型零部件的工作尺寸计算............................................................173.4.1工作尺寸分类和规定.................................................................173.4.2影响制品尺寸误差的因素.........................................................183.4.3成型零件工作尺寸计算.............................................................203.5本章小结............................................................................................25第4章浇注系统的设计.............................................................................274.1主流道的设计....................................................................................274.2分流道的设计....................................................................................284.3浇口的设计........................................................................................284.4冷料穴的设计....................................................................................294.5浇口套的设计....................................................................................304.6排气方式...........................................................................
