浙江工業大學之江學院畢業設計（論文）中文摘要I老板椅底支架注塑模具設計【摘要】注塑模的結構是由塑料制品結構、注塑機種類與規格所決定的。本文分析了面蓋的結構工藝特點，根據注射成型工藝、注塑模具設計、模具制造等理論知識及要求，結合生產實習的綜合性知識，工藝特點及功能、技術要求，參考現有的注塑模具設計資料，完成了對面蓋注塑模具的方案設計。通過設計計算，完成了注塑機型號的選用與校核，分型面和行腔數目的確定，完成了澆注系統、冷卻裝置、脫模機構等注塑模總體結構和部件的設計。利用Autocad繪制出注塑模具的總裝配圖和部分零件圖，最后，利用UG軟件完成了注塑模具的零件造型。【關鍵詞】支架，注塑機，分型面，澆注系統浙江工業大學之江學院畢業設計（論文）英文摘要Frameinjectionmolddesign【Abstract】injectionmoldstructureisformedbyplasticinjectionmoldingmachinestructure,typesandspecificationsofthedecision.Thispaperanalysesthesurfacecoverstructuretechnologycharacteristics,accordingtotheinjectionmoldingprocess,molddesign,moldmanufacturingandothertheoreticalknowledgeandrequirements,combinedwiththeproductionpracticeofintegratedknowledge,processcharacteristicsandfunction,technicalrequirements,withreferencetotheexistinginjectionmolddesign,completedthecapinjectionmolddesign.Throughdesigncalculation,completionoftheinjectionmachinetypeselectionandcheck,thepartingsurfaceandcavitynumberdetermination,completedthepouringsystem,coolingdevice,demouldingmechanismsuchasinjectionmoldtheoverallstructureandcomponentsofthedesign.TheuseofAutocaddrawingforinjectionmoldassemblydrawingandpartsdrawing,finally,useUGsoftwaretocompletetheinjectionmoldpartsmodeling.【Keywords】bracket,injectionmoldingmachine,thepartingsurface,gatingsystem浙江工業大學之江學院畢業設計（論文）目錄目錄1緒論·················································································11.1課題的背景及意義··········································································11.2注塑模具工業發展的概況及應用現狀··················································11.3注塑模在國內外的研究現狀和發展趨勢···············································11.4本設計的主要任務··········································································22注塑工藝分析[12][13]·································································32.1塑件工藝分析················································································32.2化學和物理特性·············································································32.3注塑模工藝···················································································33注射機的選擇與校核······························································73.1注射機型號初選·············································································73.2注射機參數的校核··········································································74型腔布局與分型面的設計························································84.1型腔數目及布局的確定····································································84.2分型面的設計················································································85澆注系統的設計····································································95.1主流道的設計················································································95.2分流道的設計················································································95.3澆口的設計·················································································105.4排氣的設計·················································································105.5冷料穴的設計··············································································116成型零件的設計··································································126.1成型零件工作尺寸計算··································································126.2型腔壁厚與支撐板厚度的計算·························································157冷卻裝置設計·····································································177.1冷卻計算····················································································178合模導向機構的設計····························································209脫模機構的設計··································································2110模架的選擇·······································································2311總裝圖說明·······································································24浙江工業大學之江學院畢業設計（論文）目錄IV結論··················································································25參考文獻·············································································26致謝··················································································27浙江工業大學之江學院畢業設計（論文）圖目錄
