DVD板模具注塑说明书

辽宁科技大学本科生毕业设计IDVD装饰板注塑模设计摘要塑料工业在社会中起到越来越重要的作用，影响着我们的衣食住行。此次模具设计的题目是《DVD装饰板注塑模具设计》。这个塑件是个薄壁体，尺寸相对比较小，通过对塑件的工艺性分析，选出合理的注塑机注塑。本人认真仔细的分析图纸，对分型面，浇注系统成型零件的结构，脱模推出机构，模架，冷却系统进行了详细的设计，并附上图。该模具采用一模四腔的布局，其中浇口设计与成型零件的设计进行着重说明，通过这次的设计，对模具的发展，作用有了更深的认识，把理论知识能运用到这次设计中去，并能熟练地用绘图软件将其画出来，此DVD装饰板采用侧浇口的方式进行浇注。塑件采用ABS材料，该材料密度为1.02g/3cm—1.16g/3cm，平均收缩率为0.55%，该模具结构简单，使用寿命长，可进行大批量生产。关键字：DVD装饰板，ABS,成型零件，浇注系统，浇口辽宁科技大学本科生毕业设计IIIDVDdecorativeplateinjectionmolddesignABSTRACTTheplasticsindustryplaysanincreasinglyimportantroleinsociety,affectourbasicnecessitiesoflife.TheproblemofthemolddesignistheDVDdecorativeplateinjectionmolddesign..Thisplasticpartisathinwall,thesizeisrelativelysmall,throughtheplasticpartsoftheprocessanalysis,chooseareasonableinjectionmoldingmachineinjectionmoldingmachine.Icarefullyanalysisofthedrawings,binarytype,structureofgatingsystem,formingparts,demouldinglaunch,mold,coolingsystemweredetaileddesign,andtheenclosedfigure.Themoldwithamoldfourcavitylayout,thegatedesignandformingpartofthedesignareemphaticallydescribed,throughthedesign,tomoldthedevelopment,theroleofthedeeperunderstanding,thetheorycanbeappliedtothedesignto,andcanskillfullyusedrawingsoftwaretodrawitout.ThisDVDdecorativeboardthesidegateforcasting.PlasticpartsusingABSmaterial,thematerialdensityof1.16g/-1.02g/,theaverageshrinkageof0.55%,themoldstructureissimple,longlife,canbemassproduction.Keywords:DVDdecorativeplate,ABS,moldingparts,gatingsystem,gate辽宁科技大学本科生毕业设计III目录摘要................................................................................................................................................11.绪论...........................................................................................................................................11.塑料工业的发展................................................................................................................12.模具的材料类型..............................................................................................................22、塑件成型工艺分析.......................................................................................................42.1成型材料性能分析.......................................................................................................52.2塑件结构工艺性分析...................................................................................................62.3分型面位置的确定........................................................................................................61）分型面确定..............................................................................................................72.4注射机型号的选择确定...............................................................................................71）注射量的计算..........................................................................................................82）锁模力的计算..........................................................................................................83)选择注射机...............................................................................................................84)注射机参数的校核...................................................................................................93.浇注系统的设计................................................................................................................113.1浇注系统的基本要点..................................................................................................113.2主流道设计....................................................................................................................121)主流道尺寸...............................................................................................................122)主浇道衬套设计......................................................................................................123)主流量凝料体积......................................................................................................134)主流道剪切速率校核.............................................................................................133.3分流道设计....................................................................................................................141）分流道布置形式...................................................................................................142）分流道长度............................................................................................................143）分流道形状、截面尺寸及凝料体积...............................................................144）分流道剪切速率校核..........................................................................................153.4浇口设计........................................................................................................................16（1）浇口尺寸确定......................................................................................................16(2)浇口剪切速率的校核...........................................................................................173.5冷料穴.............................................................................................................................184.成型零件的结构设计及计算......................................
