黑龙江工程学院本科生毕业论文I摘要塑料模具是塑料工业生产过程中利用特定形状，通过特定的方式来成型塑料制品的一种生产工艺装备。模具的设计与制造技术，特别是设计与制造大型、精密、长寿命模具的技术，已成为衡量一个国家机械制造水平的重要标志。本文是隐形眼盒的结构选择及其注塑模具结构的分析，隐形眼镜盒属于日常生活用品，所用原料是当前应用较为广泛的热塑性塑料ABS。该隐形眼镜盒具有：结构简单，外形美观；表面光滑，粗糙度小；结构强度高，经久耐用等特点。本文研究内容为：使用Pro/ENGINEER软件的零件制造模块设了计眼镜盒结构形状；用Pro/ENGINEER软件的模具制造模块对眼镜盒进行模具装配；分析了眼镜盒分型面并设计出了模具浇注系统；对模具的动、定模板进行了开模设计；用EMX软件对设计好的模具进行了模架的总装配并对装配好的模具进行了开模测试分析。设计使用Pro/ENGINEER制图软件对隐形眼镜盒模具进行设计，实现了隐形眼镜盒及其模具结构的成功设计和分析。设计结果的模具开模测试证明模具具有良好的可行性与经济性，与传统的设计方法相比，这种设计方法不仅提高了生产效率，同时提高了产品的质量，模具结构整体设计思路和要求符合现代模具设计潮流，符合现代模具设计的发展趋势。关键词：模具；注塑成型；模具设计；注塑模具；Pro/ENGINEER软件；隐形眼镜盒黑龙江工程学院本科生毕业论文IIABSTRACTPlasticmoldisakindofcraftequipmentintheplasticindustrialproductionwhichusesthespecificshapeandshapesplasticproductsthroughcertainway.Themolddesignandmanufacturingtechnology,specially,thedesigningandmanufacturingthelarge-scale,preciseandlong-lifemoldhasbecomeanimportantsymbolofthelevelofanationalmechanicaldesignandmanufacture.Thisarticleisstructureselectionandinjectionmoldstructureanalysforthecontactlensesbox.ThisproductisakindofdailynecessitiesanditsmaterialisthermoplasticABS.ABSisakindofmaterialwhichiscurrentusedquitewidespread.Itsproductionbatchisthemassproductionandhasthecharacteristics:simplestructure,beautifulappearance;smoothsurface,alsothesurfaceroughnessissmall;highstrengthanddurabilityoftheproduct.Thedesignfortheresearchcontent:usingPro/Esoftwarepartsmanufacturingmodulesetplancontactlensesboxstructureshape;withPro/Esoftwaremoldmanufacturemoduletothecontactlensesboxforthemoldassembly;analyzesthecontactlensesboxofpartingsurfaceanddesignsamoldcastingsystem;themovetomoldandsetthetemplatefortheopenmolddesign;withEMXsoftwaretodesignmoldoftheformworktotalassemblyandtotheassemblymoldcavitytestanalysis.ThedesignusingPro/edrawingsoftwaretoinvisiblecontactlensesboxofmolddesign,realizesthecontactlensesboxofthesuccessofthemolddesign.Thedesignofthemoldcavitytestresultsprovethatmoldhasgoodfeasibilityandeconomicalefficiency.Comparedwiththetraditionaldesignmethod,thiskindofdesignincreasesproductivityandproductquality.Theoveralldesignmentalityandrequestconformtothemoderndesigntidalanddevelopmentdirectionofthefuture.Keywords:Mold；PlasticMolding；MoldDesign；InjectionMolding；Pro/ENGINEER；ContactLensesBox黑龙江工程学院本科生毕业论文目录摘要.........................................................................................................................................IAbstract.................................................................................................................................II第1章绪论......................................................................................................................11.1课题背景与研究意义................................................................................................11.2模具的概念及其应用................................................................................................11.2.1模具..................................................................................................................11.2.2模具在国民经济中的重要作用及地位..........................................................21.3国内外模具工业发展现状与发展趋势....................................................................21.3.1国外模具工业发展概况...................................................................................21.3.2国内模具工业发展现状..................................................................................41.3.3塑料模具发展现状..........................................................................................41.3.4计算机软件在现代模具工业中的应用..........................................................61.3.5注塑模具未来发展趋势...................................................................................71.4研究内容....................................................................................................................8第2章塑件设计...............................................................................................................92.1塑件的选材.................................................................................................................92.1.1ABS的性能......................................................................................................92.1.2ABS的注射成型过程及工艺参数................................................................102.2塑件的尺寸精度.......................................................................................................102.3塑件的表面质量.......................................................................................................102.4塑件壁厚...................................................................................................................112.5脱模斜度...................................................................................................................112.6加强筋.......................................................................................................................112.7圆角...........................................................................................................................112.8塑件的表面形状.................................................................
