摘要I塑料水壶外壳注塑模设计专业：材料成型机控制工程学号：学生姓名：指导老师：摘要本课题主要是针对塑料水壶外壳的模具设计。塑料水壶外壳具有质量轻、易于清洁、强度高、使用寿命长、价格低廉、制品美观等特点。通过对塑件进行工艺分析和比较，根据制品的性能及特点，最终设计出一副注塑模。该课题从产品结构工艺性、具体模具结构特点出发，对产品的三维造型，分型面，模具的浇注系统、其成型部分的结构、冷却系统、脱模机构，注塑机的选择及有关参数的校核都有详细的设计，同时简单的说明了该模具的加工工艺。通过整个设计过程表明此模具能够达到塑件所要求的加工工艺。依据产品的数量和塑料的工艺性能确定塑件采用注塑成型法生产。该产品设计为大量批准生产，故设计的模具要求有较高的注塑效率，浇注系统要能够自动脱模，依据产品结构特征采用侧浇口，因此选用大水口模架，侧浇口自动脱模结构。模具采用一模一腔布置，浇注系统采用侧浇口成型，由六推杆推出机构完成塑件的推出。考虑到产品结构等因素，采用循环冷却系统对制件进行冷却。关键词：注塑模具；塑料水壶外壳；聚丙烯AbstractmolddesignfortheplastickettleshellAbstractThemaintopiciscovredinmolddesignfortheplastickettleshellwithalightweight，easytoclean,highstrength,longservicelife,lowprices,goodapperancequalityandsoon.Throughtheprocessofplasticpartsforanalysisandcomparison,inthelightoftheperformanceandfeatureoftheproduct,wedesignaninjectionmoldfinally.Processfromtheproductstructureoftheproject,specificmoldstructurestartingonthecastingmoldsystem,therearedetialeddesignwit,hthethre-dimensionalmodeling,binarytypesurface,gatingsystem,themouldstucture,coolingsystem,demouldingmechanism,thechoiceoftheinjectionmoldingmachine,andthecheckofsomerelatedparameter,andintroducethemoldprocessessimply.Throughtheentiredesignprocessthatcanbeachievedinthemoldplasticpartsrequiredinthisprocess.Basedonthevolumeanddeterminetheprocessperformanceofplasticinjectionmoldingmethodusingplasticpartsproduction.Theproductisdesighnedformassproduction,sothedesignofthemoldrequiresahighinjectionefficiency,andthegatingsystemtobeabletoautomaticmoldejection.,inadditiontousesitegateaccordingtoproductstructuralfeature,sowechooseasinglesubserfaceinjectionmold,sitegateautomaticejectionstructure.Moldcavityone-cavitymold,gatingsystemusingsitegateforming,introduedextrusiondevicetocompletesixthputtingtheintroductionofplasticparts.Inconsiderationofthefactorssuchastheperformanceandsoon,usecirculatingcoolingsystemtocoolproducts.Keywords:injietionmould；Plastickettleshell；Polypropylene目录III目录摘要................................................................................................................错误!未定义书签。Abstract.........................................................................................................错误!未定义书签。目录.............................................................................................................................................Ⅲ第一章对塑料成型模具的认识..................................................................................11.1模具在加工工业中的地位..............................................................................11.2模具的发展趋势...................................................................................................11.3设计在学习模具制造中的作用..................................................................3第二章塑件制品分析.......................................................................................................42.1塑件工艺分析.......................................................................................................42.2塑料水壶外壳材料的成型特性与工艺参数.......................................42.3.制品的结构工艺性.............................................................................................52.4.注塑机的选择.......................................................................................................6第三章分型面及浇注系统的设计...........................................................................103.1分型面的选择.....................................................................................................103.2浇注系统的设计.................................................................................................113.2.1主流道和定位圈的设计...................................................................123.2.2分流道的设计.........................................................................................133.2.3浇口的设计..............................................................................................143.2.4冷料穴的设计.........................................................................................163.2.5排气系统的设计....................................................................................17第四章分型面及浇注系统的设计...........................................................................184.1型腔布置................................................................................................................184.2成型零件的结构确定.....................................................................................184.2.1型腔设计..................................................................................................184.2.2型芯设计..................................................................................................19目录IV4.2.3侧向分型与抽芯机构设计.............................................................194.3导向定位机构设计...........................................................................................214.4顶出机构设计.....................................................................................................224.5.温度调节系统的设计.....................................................................................234.5.1.冷却系统的设计.........................................................................
