家用电风扇叶片注塑模具设计毕业设计

杭州电子科技大学本科毕业设计I摘要本论文阐述一套用于生产风扇叶片的注塑模具设计，给定参数：风扇直径30CM，风扇功率45W来进行设计。设计时首先设计出塑件模型，然后选择合适的材料，接下来再进行模具设计（此次设计应用Pro/E野火4.0版设计）。包括设计模具的成型系统、浇注系统、冷却系统、导向系统、脱模系统等。设计的重点在于成型系统和浇注系统与脱模系统，而成型系统的重点在于分型面的设计，它决定了型芯和型腔结构以及模具的质量。因为扇叶塑件比较特殊，叶片的厚度较薄，所以浇注系统浇口和主分流道的选择显得尤为重要。在设计中,通过合理设计推出机构和脱模机构，保证了扇叶脱模时受力均匀，避免了叶片变形、扭曲。最后，通过选用合适的标准模架，设计出一套完整的模具。此外,为保证设计合理，对注塑件进行各种工艺仿真，提高了模具的设计效率！关键词：风扇叶片；注塑模具；Pro/E设计；分型面；成型系统；浇注系统杭州电子科技大学本科毕业设计IIABSTRACTThispaperneedtodesignasetofinjectionmoldsfortheproductionoffanblade.Givenparameters:fandiameter30CM,fanpower45W.Firstlythedesignationshoulddesignplasticmodel,andthenselecttheappropriatematerials,thenyoucandesignthemouldsystem.Thesystemincludesmoldingsystem,pouringsystem,coolingsystems,guidancesystems,moldreleasesystemandsoon.Theimportancearemoldingsystemandpouringsystem.Theimportanceofthemoldingsystemisdesigningpartingsurface,itinfluentCoreandcavitystructureandthequalityofthemold;Asthebladeisverythin,thedesignationofpouringsystemismoreimportant.Ofcourse,IntroducedinstitutionsandStrippinginstitutionsmustalsobecarefullydesigned.Themoldinginstitutionslikebladesmustbeevenbyforce,otherwisethebladeiseasilydeformedanddistorted.Atlast,chooseastandardmoldbasetoformacompletesetofmolds.Butduringthedesignprocess,youmustdovarioussimulationtoavoidingproblemsintheproductionprocess!Keywords:fanblades;partingsurface;Pro/E;injectionmouldformingsystem;gatesystem杭州电子科技大学本科毕业设计III目录第一章前言.....................................................................................................................11.1研究的意义..........................................................................................................11.2国内外研究动态..................................................................................................11.3设计的任务和要求..............................................................................................3第二章风扇造型和材料选择.........................................................................................42.1风扇造型..............................................................................................................42.2材料选择..............................................................................................................5第三章工艺分析.............................................................................................................63.1总体分析..............................................................................................................63.2拔模检测..............................................................................................................63.3厚度检测..............................................................................................................73.4浇口分析..............................................................................................................73.5注射机选择..........................................................................................................8第四章成型系统设计...................................................................................................104.1装配参照模型....................................................................................................104.2设置收缩率........................................................................................................104.3创建工件............................................................................................................114.4创建分型曲面....................................................................................................114.5创建模具体积快................................................................................................114.6拉杆设计............................................................................................................12第五章浇注系统设计...................................................................................................135.1主流道设计........................................................................................................135.2分流道设计........................................................................................................145.3浇口设计............................................................................................................145.4冷料穴设计........................................................................................................15第六章冷却系统设计...................................................................................................16第七章合模导向机构设计...........................................................................................177.1导柱的设计........................................................................................................177.2导柱的布置........................................................................................................187.3导套的设计........................................................................................................187.4导柱与导套的配合............................................................................................19第八章推出机构设计..................................................................................
