排水管頭造型與模具設(shè)計(jì)摘要我所學(xué)習(xí)的專業(yè)是模具設(shè)計(jì)與制造專業(yè)，這次的畢業(yè)設(shè)計(jì)是排水管頭造型與塑料模具設(shè)計(jì)。該設(shè)計(jì)結(jié)合大學(xué)三年來(lái)所學(xué)習(xí)的專業(yè)知識(shí)和CAD軟件所設(shè)計(jì)出的一套塑料模。本文首先簡(jiǎn)要的概述了塑料模在社會(huì)領(lǐng)域中的作用及其以后的發(fā)展方向，點(diǎn)明模具設(shè)計(jì)的重要意義。然后依據(jù)工件圖進(jìn)行工藝性分析，進(jìn)而確定了設(shè)計(jì)方案，計(jì)算出模具工作部分的尺寸，設(shè)計(jì)出工作零部件；然后依據(jù)設(shè)計(jì)要求選擇出各個(gè)標(biāo)準(zhǔn)零部件，然后設(shè)計(jì)出模具的總裝配圖。在設(shè)計(jì)中，最重要的就是設(shè)計(jì)方案的確定、坯料的計(jì)算和選取以及工作零部件的設(shè)計(jì)，這是設(shè)計(jì)的關(guān)鍵，這些設(shè)計(jì)的正確與否直接關(guān)系到成本的高低和設(shè)計(jì)模具能否正常工作；在設(shè)計(jì)的最后，總結(jié)了自己的心得和體會(huì)，并對(duì)我的指導(dǎo)老師表示感謝。為了我的設(shè)計(jì)更加簡(jiǎn)明易懂，在設(shè)計(jì)中，我用了十幾張零件圖來(lái)說(shuō)明我的設(shè)計(jì)意圖，安插在設(shè)計(jì)任務(wù)書中。最后畫出一幅排水管頭塑料模裝配圖和主要工作零部件零件圖若干張。通過(guò)本次畢業(yè)設(shè)計(jì)使我不僅掌握了塑料模具設(shè)計(jì)的一般流程，更學(xué)習(xí)到了好多課本上沒(méi)有學(xué)習(xí)到的知識(shí)，使我受益匪淺。關(guān)鍵詞：模具設(shè)計(jì)與制造、CAD軟件、工藝性分析。HeadmodellingandmolddesignofdrainpipeSummaryThespecialityofstudyofourinstituteisthemolddesignandspecialityofmaking,thegraduationprojectthistimeisheadmodellingofthedrainpipeandplasticmolddesign.ItstimetodesignandcombinetheprofessionalknowledgeofstudyandasetofplasticmouldsthatCADsoftwaredesignedoverthepastthreeyearsofuniversity.Thistextthebriefplasticroleinsocialfieldofmouldofsummaryanddevelopingdirectionafterwardsatfirst,pointoutintheimportantmeaningofmolddesign.Thencarryonthecrafttoanalyseaccordingtotheworkpiecepicture,andthenhasconfirmedthedesignplan,calculateoutmouldworksomesize,designthejobsparepart；Thenchooseeachstandardsparepartaccordingtothedesigningrequirement,thendesignthetotalinstallationdiagramofthemould.Inthedesign,theimportantoneissurenessofthedesignplan,calculationandchoosingandworkingthedesignofthesparepartoftheblankthemost,thisisthekeytodesigning,whethertheseonesthataredesignedinvolvedirectlyornotcorrectlywhetherthelevelofthecostanddesignmouldcouldworknormally；Attheendthatisdesigned,havesummarizedonesowngainsandexperience,andexpressthanksformycounselor.Moreconcislyandeasyformydesignunderstands,inthedesign,Istatemydesignintentionwithadozenpartspicture,assignintodesignspecifications.Drawadrainpipeandseveralplasticmouldinstallationdiagramsofverybeginningandsparepartpicturesofthegroundworkfinally.Makemenotmerelygraspthegeneralprocedureofplasticmolddesignthroughgraduationprojectonce,studytotheknowledgenotlearningtogetonmanytextbooksevenmore,benefitmeagreatdeal.Keyword:Molddesignandmaking,CADsoftware,craftanalysis.目錄緒論11.本課題的意義、目的及應(yīng)達(dá)到的要求12本課題的國(guó)內(nèi)外現(xiàn)狀13國(guó)外塑料模具的發(fā)展現(xiàn)狀44本設(shè)計(jì)所要解決的問(wèn)題51工藝性分析61.1：塑料的原材料分析61.2：塑件的結(jié)構(gòu)和尺寸精度等級(jí)及表面質(zhì)量分析61.3：計(jì)算塑料制件的體積和質(zhì)量71.4：ABS塑料注射成型的工藝參數(shù)71.5：塑料成型設(shè)備的選取82注塑模具結(jié)構(gòu)的設(shè)計(jì)92.1模腔數(shù)量的確定92.2分型面的選擇以及型腔的排列方式的確定102.3澆注系統(tǒng)的設(shè)計(jì)112.4模具側(cè)向分型機(jī)構(gòu)122.5抽芯距的確定133模具工作零件的設(shè)計(jì)153.1凹模的設(shè)計(jì)153.2排水管頭注塑模具的工作尺寸153.3型芯結(jié)構(gòu)的確定164模具加熱和冷
