塑料旋钮注塑模具设计摘要塑料工业是当今世界上增长最快的工业门类之一,而注塑模具是其中发展较快的种类,因此,研究注塑模具对了解塑料产品的生产过程和提高产品质量有很大意义。本设计产品名称风扇按钮,选材料为聚氯乙烯,因为产品的需求,我们选择采用一模四腔的排列方式,根据模具结构,我们应用推杆推出工件方法。通过本设计,可以对注塑模具有一个初步的认识,注意到设计中的某些细节问题,了解模具结构及工作原理;通过对CAD的学习,可以建立较简单零件的零件库,从而有效的提高工作效率。关键词:侧向分型抽芯机构斜顶机构AbstractTheplasticsindustryistheworld'sfastestgrowingindustriesontheonecategory,whiletheinjectionmoldisoneofthetypesofrapiddevelopment,therefore,researchontheunderstandingofplasticinjectionmoldingproductionprocessandimproveproductqualityisverysignificant.Thenameoftheskeletondesignproducts,choosematerialsforthePP,becausethedemandfortheproduct,wechooseatwo-cavitymoldarrangement,accordingtomoldstructure,weappliedthelateraltypePullingMechanismdesignandthedesignofthelifterbody.Throughthisdesign,injectionmoldcanhaveapreliminaryunderstandingofthedesignofsomeofthedetailsofthenoteissue,tounderstandthestructureandworkingprincipleofmold;bylearningCAD,partscancreatesimplepartslibrary,soastoeffectivelyincreaseefficiency.Keywords:lateraltypecore-pullingmechanismlifterbodies目录绪论.............................................................................................................................................1第1章塑件的工艺分析...........................................................................................................31.1塑件的材料...................................................................................................................31.2工艺分析.......................................................................................................................5第2章拟定模具结构形式.......................................................................................................62.1分型面的确定...............................................................................................................62.2确定型腔数目和排列方式...........................................................................................6第3章浇注系统的设计...........................................................................................................93.1主流道设计...................................................................................................................93.2分流道设计...................................................................................................................93.3主流道剪切速率的校核.............................................................................................103.4浇口的设计.................................................................................................................10第4章成型零件的设计.........................................................................................................124.1成型零件的结构设计.................................................................................................124.2成型零件钢材选用.....................................................................................................124.3动模的大小.................................................................................................................124.4主要成型零件的工作尺寸的计算....
