基于CAD/CAM/CAPP的按钮注塑模具设计与制造工艺摘要:模具是塑料成型加工的一种重要的工艺装备,同时又是原料和设备的“效益放大器”,模具生产的最终产品的价值,往往是模具自身价值的几十倍、上百倍。因此,模具工业已成为国民经济的基础工业,被称为“工业之母”。模具生产技术的高低,已成为衡量一个国家产品制造技术的重要标志。塑料成型加工及模具技术不仅随着高分子材料合成技术的提高、成型设备成型机械的革新、成型工艺的成熟而进步,而且随着计算机技术、数值模拟技术等在塑料成型加工领域的渗透而发展。本文主要讲述了按钮注塑模的设计。内容包括制品材料的选择及材料性能的分析、注射机的选用、浇注系统、成型零件、冷却系统和抽芯机构的设计等部分。除此之外,还包括模具型腔的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、CAXA等国内外著名软件进行辅助设计。既保证了产品的质量,缩短了产品更新的周期通过本次毕业设计,对我在大学阶段所学习的模具设计方面知识做了一个很好的总结和巩固,也对平时所学习的比较零散的知识做到了系统化的运用。也发现了自己在学科仍存在很多不足,可以更好的复习和理解,同时对机械制造、加工的工艺有了一个系统、全面的理解,达到了学习的目的。关键词:按钮;注塑模;CAD/CAM/CAPPButtoninjectionmolddesignandmanufacturingprocessbasedonCAD/CAM/CAPPAbstract:Mouldplasticmoldingprocessisanimportanttechnologicalequipmentandrawmaterialsandequipment"benefit",mouldmanufacturingamplifiers,finalproductvalue,isoftendieworthseveraltimes,ahundredfold.Therefore,themoldindustryhasbecomethefoundationofthenationaleconomywork,calledthe"motherofindustry.Mouldmanufacturingtechnology,hasbecomeanationalproductmanufacturingtechnologyoftheimportantsymbol.Theplasticmoldingprocessandmouldtechnologynotonlywiththepolymermaterialssynthesistechnologyimprovementandinnovationofmoldingmachinerymoldingequipment,moldingprocessofpracticeandprogress,andalongwiththecomputertechnology,thenumericalsimulationtechnologyinthefieldofplasticforminganddevelopmentpenetration.Thisarticlemainlydescribedthedesignofinjectionmouldhelmet.Contentsincludethechoiceofmaterialsandproductsofmaterialpropertiesofanalysis,injectionmachineselection,gatingsystem,formingzeroA,coolingsystemandthedesignofcore-pullingmechanismetc.Inaddition,alsoincludingthemoldCAD/CAM,andusetheadvancedsoftwarewillitsprocessingpartsDeliverytotheNCfiles.Thepaperemphasizesusingmoderncomputeraideddesignmanufacturetechnology,usingCAXANX8.5domesticandinternationalfamoussoftwareetc.bothEnsurethequalityofproducts,butalsogreatlyimprovethemanufacturingproductivity,shortenthecycleofproductupdate.Throughthegraduationdesign,formeintheuniversitylearningstageofmoulddesignaspectsofknowledgeisagoodsummaryandconsolidate,thepeacetimelearningisscatteredknowledgeachievedsystematicapplication.Alsofoundhimselfinsomeaspectofknowledgewithinashort,doowethegoodreviewandunderstandingofmechanicalmanufacturing,processingtechnologyisasystematicandcomprehensiveunderstanding,reachedthepurposeoflearning.Keywords:Helmet,Injectionmold,CAD/CAM/CAPP目录第1章绪论.................................................................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...........................................2第2章塑件的工艺性分析......................................................32.1塑件的原材料分析.................................
