陕西理工学院毕业论文基于PRO/E矿泉水瓶盖注塑模具改进设计[摘要]此次设计是对矿泉水瓶盖注塑模的设计，包括对它的工艺分析，材料性能，设备选择，尺寸计算等内容。由于此塑件内部有螺纹，所以主要解决了塑件脱模方式的选择，脱模机构的设计，型腔的设计，以及模腔数目的确定等问题。经过对比采用螺牙旋转出模具，已达到预期目的。[关键词]：注塑模，脱模机构，螺纹I陕西理工学院毕业论文ImprovementBasedonPRO/EmineralwaterbottleinjectionMoldsAbstract:Thedesignisamineralwaterbottleinjectionmolddesign,includingitsprocessanalysis,materialproperties,equipmentselection,sizingandsoon.Becauseinsidethisplasticpartsarethreaded,sothemainchoicetosolvetheplasticstrippingmethods,designreleasingmechanism,cavitydesign,andmoldcavitytodeterminethenumberofotherissues.Aftercomparingtheuseofthreadrotatedoutofthemold,ithasreachedtheintendedpurpose.Keywords:Injectionmold,ejectionmechanism,threadII陕西理工学院毕业论文目录摘要......................................................................................................IAbstract...............................................................................................II1前言..................................................................................................12塑件的工艺分析..............................................................................22.1塑件的型工艺分析..........................................................................22.1.1壁厚分析.................................................................................22.1.2圆角分析.................................................................................32.2塑件材料的选择及材料特性..........................................................32.2.1材料的选择.............................................................................32.2.2材料特性.................................................................................32.3方案选择..........................................................................................43注射设备的选择..............................................................................63.1估算塑件的体积和质量..................................................................63.2选择注射机......................................................................................63.3注塑机相关参数的校核..................................................................73.3.1最大注射量的校核.................................................................73.3.2注射压力的校核.....................................................................73.3.3锁模力的校核.........................................................................74塑料件的工艺尺寸的计算...............................................................8III陕西理工学院毕业论文4.1型腔尺寸..........................................................................................84.1.1型腔径向尺寸.........................................................................84.1.2型腔深度尺寸.........................................................................84.2计算螺纹型芯的工作尺寸..............................................................94.3脱模机构的设计............................................................................104.3.1脱模力计算...........................................................................105型腔数目的确定及排布...................................................
