辽宁科技大学本科生毕业设计DVD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/—1.16g/，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辽宁科技大学本科生毕业设计DVDdecorativeplateinjectionmolddesignABSTRACTTheplasticsindustryplaysanincreasinglyimportantroleinsociety,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................................................................................
