I西南科技大学城市学院本科生毕业论文基于CAD/CAM/CAPP的灭火器盖注塑模具设计与制造工艺摘要：本文详细地阐述了灭火器外壳塑件注射模具的设计过程与制造工艺。设计了注射模具中的各个系统，如浇注系统、导向与定位机构、侧向分型与抽芯机构，并对塑料材料性能进行了分析。根据塑件的产品数量要求，以及结构要求，该模具采用一模一腔。使用UG软件设计成型零件以及非标零件，即对模具进行分模、生成元件、装配、试模、开模等设计。除此之外，还包括模具型腔CAD/CAM/CAPP部分，并利用先进软件将其加工部分直接生成NC文件。本文强调利用现代计算机辅助设计制造技术，运用了NX8.5等国内外著名软件进行辅助设计。既保证了产品的质量，又缩短了产品更新的周期。同时可快捷的将三维图转化为二维工程图，直接指导生产。关键词：注射模；灭火器盖；CAD/CAM/CAPPII西南科技大学城市学院本科生毕业论文BasedonCAD/CAM/CAPPoffireextinguishercoverinjectionmolddesignandmanufacturingprocessAbstract:Thisarticleindetailelaboratesthefireextinguishertheshelloftheinjectionmoulddesignprocessandmanufacturingprocess.Designoftheindividualsystemoftheinjectionmould,suchaspouringsystem,guidingandpositioning,sidepartingandcore-pullingmechanism,andtheplasticmaterialperformanceisanalyzed.Accordingtotherequirementsoftheplasticproducts,aswellasstructuralrequirements,themouldwithonemoduleandonecavity.UsingUGsoftwaredesignofmoldingpartsandnon-standardparts,namelythemouldparting,generation,components,assembly,testmode,openmoulddesign.Inaddition,alsoincludingCAD/CAM/CAPPpartofthemoldcavity,andusetheadvancedsoftwaretoitsprocessingpartgenerateNCfilesdirectly.Thisarticleemphasizestheuseofmoderncomputeraideddesignandmanufacturingtechnology,usingthefamousathomeandabroadsuchasNX8.5aideddesignsoftware.Guaranteethequalityoftheproductsandshortenthecycleofproductupdates.Atthesametime,canquicklyconvertthree-dimensionalfigureintotwo-dimensionalengineeringgraphics,directproductiondirectly.Keywords:Injectionmould,Fireextinguishercover,CAD/CAM/CAPPIII西南科技大学城市学院本科生毕业论文目录第1章绪论.........................................................11.1模具行业发展的现状.......................................................................................11.2设计任务...........................................................................................................2第2章塑件的工艺分析..............................................................................................32.1塑料材料分析...................................................................................................32.1.1塑料材料的基本特性.............................................................................32.1.2塑件材料主要用途.................................................................................32.1.3成型工艺性分析.....................................................................................42.2塑件的结构.......................................................................................................42.2.1灭火器盖塑件.........................................................................................42.2.2结构特点分析.........................................................................................62.2.3塑件尺寸精度及表面质量分析.............................................................6第3章塑件成型工艺与设备......................................................................................73.1注塑成型工艺因素.............................................
