I畢業(yè)設(shè)計（論文）說明書題目名稱：摩托車后燈罩注塑模具設(shè)計摘要本文詳細(xì)地闡述了蓋注射模具的設(shè)計過程。設(shè)計了注射模具中的各個系統(tǒng)，如澆注系統(tǒng)、導(dǎo)向與定位機(jī)構(gòu)、側(cè)向分型與抽芯機(jī)構(gòu)，并對塑料材料性能進(jìn)行了分析。根據(jù)塑件的產(chǎn)品數(shù)量要求，以及結(jié)構(gòu)要求，該模具采用一模一腔。整個設(shè)計過程都是用CAD軟件進(jìn)行參數(shù)化設(shè)計，使整個模具設(shè)計過程簡單明了。利用MPA軟件進(jìn)行模流分析，為模具設(shè)計和成型工藝的指定提供參照依據(jù)。使用CAD軟件設(shè)計成型零件以及非標(biāo)零件，從而進(jìn)行全方面的參數(shù)化設(shè)計，即對模具進(jìn)行分模、生成元件、裝配、試模、開模等設(shè)計。調(diào)用標(biāo)準(zhǔn)模架以及標(biāo)準(zhǔn)件，從而完成模具的整體設(shè)計。直接指導(dǎo)生產(chǎn)。針對塑件的特點(diǎn)，本模具設(shè)計了側(cè)抽芯滑塊機(jī)構(gòu)，II也構(gòu)成了本次模具設(shè)計的主要內(nèi)容。關(guān)鍵詞：注射模，參數(shù)化設(shè)計，側(cè)抽芯和滑塊，燈罩AbstractThispaperdescribesindetailthedesignprocessofinjectionmoldingcover.Injectionmolddesignvarioussystems,suchaspouringsystem,orientationandpositioningmechanism,sidepartingandcorepullingmechanism,andplasticmaterialpropertieswereanalyzed.Thenumberofproductsundertherequirementsofplasticparts,andstructuralrequirementsofonemoduleandoneadoptedinthemoldcavity.TheentiredesignprocessiscarriedoutusingCADsoftware,parametricdesign,theentiremolddesignprocesssimpleandstraightforward.MPAsoftwareusingmoldflowanalysis,molddesignandmoldingtechnologytoprovidereferenceforthespecified.MoldedpartsusingCADsoftwaredesignandIIInon-standardparts,whichwereallaspectsofdesignparameters,namely,thepartingofthemoldtoproducecomponents,assembly,testmode,openmode,suchasdesign.Callthestandardmoldbaseandstandardparts,thuscompletingtheoveralldesignofthemold.Directtheproduction.Characteristicsofplasticpartsforthediedesignofthesidecorepullingslidermechanism,butalsoconstitutethemaincontentsofthemolddesigntime.Keywords:injectionmold,parametricdesign,thesidecorepullingandslide,shade.-1-目錄1前言.-3-1.1模具行業(yè)發(fā)展的現(xiàn)狀.-3-1.2我國模具發(fā)展的現(xiàn)狀.-3-1.3參數(shù)化技術(shù)慨述.-4-1.4選題目的以及意義.-5-2塑件成型工藝性分析.-6-2.1摩托車尾燈罩二維圖.-6-2.2結(jié)構(gòu)特征分析及成型工藝性分析.-6-2.2.1結(jié)構(gòu)特征分析.-6-2.2.2成型工藝性分析.-6-2.2.3塑件材料的基本性能.-7-2.2.4塑料的成型收縮率.-7-2.2.5塑件材料的流動性.-7-3塑件成形工藝與設(shè)備.-8-3.1注塑成型工藝條件.-8-3.1.1溫度.-8-3.1.2壓力.-8-3.1.3時間.-8-3.2注射機(jī)型號的確定.-9-3.2.1由公稱注射量選擇注射機(jī).-10-3.2.2由鎖模力選擇注射機(jī).-10-3.3型腔數(shù)量以及注射機(jī)有關(guān)工藝參數(shù)的校核.-11-3.3.1型腔數(shù)量校核.-11-3.3.4注射壓力校核.-12-3.3.5安裝尺寸校核.-12-4注射模具結(jié)構(gòu)設(shè)計.-15-4.1型腔的確定.-15-4.2制品成型位置及分型面的選擇.-15-4.3澆注系統(tǒng)設(shè)計.-15-4.3.1主流道設(shè)計.-16-4.3.2冷料穴的設(shè)計.-17-4.3
