皖西学院本科毕业论文（设计）第I页三通管注塑模具设计作者赵大指导教师李梅摘要：三通管作为一种连接件在日常生活中应用广泛。本文主要介绍了三通管注塑模具的设计过程。本设计通过对塑件的工艺分析，确定其主要成型工艺参数，设计了三通管注塑模具中的各个系统，如浇注系统、导向与定位机构、侧向分型和抽芯机构、脱模机构、分型面、冷却系统及排气系统等，并对所选用的注塑机参数进行了校核，最后绘制出模具的装配总图，完成本文的编写。该注塑模具为双分型面结构，一模一腔，采用滚轮式滑板侧向抽芯机构，利用推杆将塑件脱出，结构合理，运行可靠。整个设计过程不仅使用了传统的设计方法，还运用了CAD、PRO/E等技术，大大提高了设计的效率。本次设计能加强对注塑模具成型原理的理解，同时锻炼了注塑模具设计和制造能力。关键词：三通管注塑模具侧抽芯Three-wayPipeInjectionMoldDesignAbstract：Thethree-waypipeasaconnectionindailylifeisusedwidely.Thispaperintroducestheprocessofthethree-waypipeinjectionmolddesign.Throughtotheanalysisofthetechnologyofplasticparts,determineitsmainmoldingprocessparameters,thedesignofinjectionmouldthree-waypipeeachofthesystem,suchasgatingsystem,orientationandthepositionoftheinstitutions,sidepartingandcore-pullingmechanism,ejectionmechanism,thepartingsurface,coolingsystemsandexhaustslot.Andcheckedtheselectedinjectionmoldingmachineparameters,finallydrawmoldassemblydrawing,completesthepreparation.Thisinjectionmoldistwojointsurfacesstructure,dyingstructureadoptedonemoduleonecavity,usedthesidecore-pullingmechanismofarollertypeslide,usingthepushrodplasticpartsprolapse,itisareasonablestructure,reliableoperation.Thewholedesignprocessnotonlyusingtraditionaldesignmethod,stilluseoftheCAD,PRO/Eandothertechnologygreatlyimprovingthedesignefficiency.Thedesignofinjectionmouldcanstrengthentheunderstandingofformingprinciple,whileexercisingtheinjectionmoldingmoulddesignandmanufacturingability.Keywords：Thethree-waypipeinjectionmoldsidecore-pulling皖西学院本科毕业论文（设计）第II页目录第1章绪论......................................................................................................................................11.1塑料成型在塑料工业中的地位..........................................................................................11.2塑料成型模具的重要性......................................................................................................11.3塑料成型技术的发展方向..................................................................................................1第2章塑件工艺分析......................................................................................................................32.1塑件图..................................................................................................................................32.2塑件原材料分析..................................................................................................................32.3塑件形状分析......................................................................................................................3第3章注塑工艺设计......................................................................................................................43.1工艺参数的计算..................................................................................................................43.1.1塑件的体积和质量的计算..............................................................................................43.1.2注塑机的选择..................................................................................................................43.2塑件注塑成型工艺参数......................................................................................................5第4章注塑模具总体设计..............................................................................................................64.1注射模浇注系统设计..........................................................................................................64.1.1主流道的设计..................................................................................................................64.1.2分流道的设计..................................................................................................................74.1.3冷料穴的设计..................................................................................................................84.1.4浇口的设计......................................................................................................................84.2分型面的设计......................................................................................................................94.3排气系统的设计..................................................................................................................94.4成型零部件设计..................................................................................................................94.4.1成型零部件的结构设计................................................................................................104.4.2成型零部件工作尺寸的计算........................................................................................114.4.3模具型腔侧壁和底板厚度的计算................................................................................134.5模架的选择........................................................................................................................134.6导向及脱模机构设计........................................................................................................134.6.1导向机构设计................................................................................................................13皖西学院本科毕业论文（设计）第III页4.6.2脱模机构设计....................................................
