心型台灯的注塑模具设计

2016届分类号:单位代码:毕业论文（设计）心型台灯的注塑模具设计姓名学号年级专业机械设计制造及其自动化系（院）机械工程学院指导教师2016年3月30摘要塑料行业是当今世界增长最快的工业类型之一，而注塑模具则是其中发展较快的类型，因此，深入对注塑模具的研究对于了解塑料产品的加工过程和提高产品加工质量有很重要的意义。本次设计介绍了注射成型模具的基本原理，特别是对单分型面注射模具的结构和工作原理，对产品提出了最基本的设计准则；详细介绍了温度调节系统和顶出系统的设计过程、冷流道注射模具浇注系统，并且对模具强度要求做了具体说明；最后介绍了当今业界上最为流行的三维CAD/CAM系统标准软件PRO/ENGNEER的PROGRAM模块，对导柱和导套进行了参数化设计。通过本次设计，可以对注塑模具有一个基本的认识，注意到设计中的出现的某些细节性问题，比较详细的了解模具的一般结构及其工作原理；通过对PROGRAM的学习，可以设立比较简单的零件的零件库，从而总体上有效的提高工作效率。关键词：塑料模具；分流道；镶件；分型面；抽芯距；AbstractMaterialsindustryistheworld'sfastest-growingtypesofindustries,Theinjectionmoldisofthetypeinwhichtherapiddevelopment,therefore,theresearchcaststhemoldtounderstandtheplasticproducttheproductionprocessandimprovestheproductqualitytohavetheverybigsignificance.Thisdesignintroducesthebasicprinciplesofinjectionmoldingdie,especiallyforasinglesub-surfaceinjectionmoldstructureandworkingprinciple,theproductpresentsbasicdesigncriteria;Detailsofthetemperaturecontrolsystemandthetopofthesystemdesignprocess,coldrunnerinjectionmoldgatingsystemandthemoldintensityrequestspecificinstructions;finallyintroducedtodaytheindustry'smostpopular3DCAD/CAMsystemstandardsoftwarePRO/ENGNEERofPROGRAMmodules,toguidepostandguidewereparametricdesignThroughthisdesign,injectionmoldcanhaveabasicunderstandingofdesignnotedtheemergenceofsomeofthedetailsoftheissue,amoredetailedunderstandingofthegeneralstructureandworkingprincipleofthemold;PROGRAMthroughlearningcanbesetuprelativelyasimplelibraryofparts,soastoeffectivelyimprovetheefficiencyofthewhole.Keyword:Theplasticmold;Shunt;inlays;dividestheprofile;Pullingaway目录1前言....................................................................11.1模具对于国民经济发展的重要作用.....................................11.2各种模具的分类和占有量.............................................21.3我国模具技术的现状及发展趋势......................................22注塑件的设计.............................................................42.1功能设计...........................................................42.2材料选择...........................................................42.3结构设计...........................................................62.3.1对塑件的修改说明.................................................62.3.2壁厚.............................................................72.3.3脱模斜度.........................................................82.3.4加强肋...........................................................82.3.5圆角.............................................................82.4塑件的尺寸精度及表面质量...........................................92.4.1尺寸精度..........................................................92.4.2塑件的表面质量...................................................103注塑成型的准备..........................................................103.1注塑成型工艺简介..................................................103.2注塑成型工艺条件..................................................103.3注塑机的选择.......................................................123.3.1注塑机简介......................................................123.3.2注塑机基本参数..................................................123.3.3选择注塑机.......................................................133.4注射机的校核......................................................143.4.1最大注塑量的校核................................................153.4.2锁模力的校核....................................................153.4.3塑化能力的校核..................................................153.4.4喷嘴尺寸校核....................................................153.4.5定位圈尺寸校核..................................................163.4.6模具外形尺寸校核................................................163.4.7模具厚度校核....................................................163.4.8模具安装尺寸校核................................................163.4.9开模行程校核....................................................164模具设计................................................................174.1塑料配方说明......................................................174.2分型面的确定......................................................174.3型腔数目的确定.....................................................184.4浇注系统设计.......................................................184.4.1主流道...........................................................194.4.2分流道...........................................................194.4.3冷料穴...........................................................204.4.4浇口.............................................................214.4.5剪切速率的校核...................................................214.5模架的确定.........................................................234.5.1型腔壁厚和底版厚度计算...........................................234.5.2模架的选用.......................................................244.7顶出系统设计.......................................................254.7.1脱模力的计算.....................................................264.7.2推杆脱模机构.....................................................284.7.3推板厚度的计算...................................................294.8成型零件工作尺寸的计算.............................................304.8.1凹模工作尺寸的计算...............................................304.8.2凸模工作尺寸...................................
