摘要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IAbstractmolddesignfortheplastickettleshellAbstractThemaintopiciscovredinmolddesignfortheplastickettleshellwithalightweight，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；PolypropyleneII目录目录摘要................................................................................................................................................IAbstract.......................................................................................................................................II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..............................................................................
