對講機后蓋的注塑模具設計說明書.doc

I摘要針對對講機后蓋進行了注塑模具設計。通過對塑件進行工藝的分析和比較,最終設計出一副注塑模。該課題從產(chǎn)品結(jié)構工藝性，具體模具結(jié)構出發(fā)，對注塑機的選擇及有關參數(shù)的校核、模具的分型面、澆注系統(tǒng)、模具成型部分的結(jié)構、推出系統(tǒng)、冷卻系統(tǒng)進行了設計。同時運用三維pro/E制圖軟件繪制該模具，與平面圖相比更具立體感。關鍵詞：注塑模具；澆注系統(tǒng)；冷卻系統(tǒng)；校核IIAbstractThistopicismainlyforradioshellmolddesign,plasticpartsthroughtheprocessofanalysisandcomparisontothefinaldesignaninjectionmold.Processfromtheproductstructureonthesubjectof,specificmoldstructuretothesub-surfaceofthemold,pouringsystem,themoldformingpartofthestructure,launchsystems,coolingsystems,injectionmoldingmachineofchoiceandtheparametersofthecalibration,aredetaileddesign.Atthesametimedrawingzhemoldsusetothree-dimensionalmappingprogramofpro/E,thiscomputergraphicssystemhastheimpastocomparedtotheplainviewdrawing.Keywords：injectionmold；systemofgating；systemofcooling；checking.III目錄摘要.IAbstract.II第1章緒論.11.1模具工業(yè)的應用概況.11.2我國塑料模具工業(yè)的發(fā)展概況.2第2章方案選擇.42.1注射模的組成與分類.42.1.1注射模的組成.42.1.2注射模的分類.52.2塑件成型工藝分析.52.2.1注射模的設計方法與研究現(xiàn)狀.52.2.2塑件分析.62.2.3制品材料的成形特性與工藝分析.82.3注射成型機的選擇.102.3.1注射量的計算.102.3.2澆注系統(tǒng)凝料體積的初步估算.102.3.3注射機的選擇.102.4分型面設計.112.4.1分型面作用、形式和設計原則.112.4.2分型面的確定.122.5型腔設計.142.5.1型腔數(shù)目的確定.142.5.2型腔排列形式的確定.152.5.3型腔壁厚尺寸的確定.152.6模具結(jié)構形式的設計.152.7模具材料的選用.18第3章部件的設計計算.193.1澆注系統(tǒng)設計.193.1.1澆注系統(tǒng)的設計原則.19IV3.1.2主流道的設計.193.1.3分流道的設計.213.1.4澆口設計.233.1.5冷料穴與拉料桿設計.243.2成型零件工作尺寸的計算.253.2.1定模板及其支撐板.253.2.2動模板及其支撐板.263.2.3墊塊.273.2.4導向機構.283.2.5側(cè)向抽芯機構：.283.3推出機構的設計.293.3.1推出機構的設計原則.293.3.2推出機構的分類.303.3.3推出力的計算.303.3.4推出零件尺寸的確定.313.3.5推桿位置的確定.323.4冷卻回路設計.333.4.1冷卻系統(tǒng)的設計原則.333.4.2冷卻水路的形式.333.4.3冷卻計算（水道的直徑wd與總長度l）.34第4章校核.374.1注射量的校核.374.2鎖模力校核.374.3最大注射壓力的校核.384.4最小模厚的校核：.384.5推出零件的強度和剛度校核.384.6冷卻水流動狀態(tài)Re的校核.39結(jié)論.40致謝.41參考文獻.42VCONTENTSAbstract.IIChapter1Introduction.11.1Plasticmould.11.2Injectionmoulddevelopmentsituationathomeandabroad.2Chapter2Selectionofscheme.42.1Injectsmouldcompositionandtheclassification.42.1.1TheformofInjectionmould.42.1.2ThesortofInjectionmould.52.2Theanalysisofplasticmoldingprocess.52.2.1Injectsmoulddesignmethodandthesituation.52.2.2Theanalysisofplastic.62.2.3Productmaterialformedcharacteristicandprocess.82.3Injectionmaxhine.102.3.1Calculationofinjectionquantity.102.3.2Thevolumeestimateofmaterialgatingsystem.102.3.3Theinjection.102.4Theselectionpartingsurface.112.4.1Thedesignprinciplesofselectionparting.112.4.2Theselectionpartingsurface.122.5Designofthecavity.142.5.1Thenumberofcavity.142.5.2Thearrangementofcavity.152.5.3Thearrangementofcavity.152.6Theformofmouldstructure.152.7Mouldmaterialschosen.18Chapter3Partsofthedesignandcalculation.1
