毕业设计论文基于PRO/E的果蔬篮注塑模具设计THEDESIGNOFINJECTIONMOULDOFFRUITANDVEGETABLEBASKETBASEDONPRO/ESOFTWARE学生姓名学院名称专业名称指导教师20年5月27日摘要塑料制品在日常生活中应用广泛,注塑模技术己成为衡量一个国家产品制造业水平的重要标志之一。在CAD/CAM技术得到普及的同时,CAE技术应用越来越广,以CAD/CAM/CAE一体化的技术得以发展,模具新结构、新品种、新工艺、新材料的创新成果不断涌现,使得注塑模的发展迅猛。本文在参考大量国内外文献的基础上,对果蔬篮进行模具设计,综合运用Pro/E和MoldFlow软件设计出一套合理的注塑模具,主要做了以下几个方面的工作运用Pro/E软件对果蔬篮进行三维模型重构根据相关理论知识,合理选用塑件材料、注塑机,模架等,并进行了相关校核运用模流分析软件MoldFlow,分析了塑件的最佳浇口位置,预测翘曲变形、熔接痕,气穴等缺陷,并校验冷却系统能力等确定了型腔数目及布局,选择分型面并进行了浇注系统设计设计型腔、型芯的结构并进行了相关尺寸计算,同时设计了侧抽芯机构及冷却系统等,最终完成整副模具的设计及装配。关键词注塑模具果蔬篮Pro/E模流分析AbstractPlasticproductsareusedwidelyinourdailylife,andthetechniqueofinjectionmoldhasbeenoneofthemostimportantmeasurementsofproductmanufacturinglevelforacountry.WhenthetechniqueofCAD/CAMisuseddiffusively,thetechniqueofCAEisalsousedmoreandmorepopular.Withthenewcomposition,newvarity,newtechniqueandnewmetarialinvented,theintegrationofCAD/CAM/CAEandinjectionmoldisdeveloping.ThisarticlerefertolotsofliteraturetoredesignaFruitandvegetablebasketmold,itusethesoftwaresofPro/EandMoldFlowtodesignareasonableinjectionmold.OurreasearchesarefocusonthefollowingaspectsTheFruitandvegetablebasket3DmodelingbyPro/E.Selectreasonableplasticmaterialsandinjectionmoldingmachinerefertosomerelevanttheoreticalknowledge.UsethesoftwareofMoldFlowtoanalysisthebestgate,predictthewarpingdeformation,weldingtrace,cavitationandexamthecapabilityofcoolingsystem.Determinethenumbersofcavitiesandlocationschoosethepartinglineanddeterminethefeedsystem.Designcavity,coresofstructure,calculatetherelevantdimensions,designsidecoreslideandcoolingsystem,ensuremoldassemble.KeywordsInjetionFruitAndVegetableBasketPro/EMoldflow徐州工程学院毕业设计论文I目录摘要..................................................................................................................................................IAbstract..........................................................................................................................................II1绪论.............................................................................................................................................11.1注塑模行业现状及其发展趋势..........................................................................................11.2本文研究内容......................................................................................................................22塑件成型工艺性分析.................................................................................................................32.1基于Pro/E的果蔬篮三维建模...........................................................................................32.2果蔬篮材料的选择及工艺性能的分析..............................................................................42.2.1材料的选择...................................................................................................................42.2.2工艺性能的分析...........................................................................................................63注塑设备选择及校核.................................................................................................................73.1塑件体积的估算..................................................................................................................73.2注塑机的选择......................................................................................................................73.3注塑机相关参数的校核......................................................................................................83.3.1注射压力的校核...........................................................................................................83.3.2锁模力的校核...............................................................................................................94分型面设计及型腔布置...........................................................................................................104.1分型面的设计....................................................................................................................104.2型腔布置............................................................................................................................125基于MoldFlow的模流分析.....................................................................................................135.1MoldFlow软件简介...........................................................................................................135.2网格的划分与处理............................................................................................................135.3塑件的最佳浇口位置分析................................................................................................155.4塑件的翘曲分析................................................................................................................155.5塑件的流动性分析............................................................................................................165.5.1气穴、熔接痕和分子表面取向.................................................................................165.5.2充填时间分析.............................................................................................................185.5.3锁模力和螺杆速度................................
