内容简介：

邵阳学院毕业设计（论文）1内容提要CD盒的形状较为复杂，所以模具设计中要考虑的因素有很多，除考虑它的出模、分型面，还需考虑它成型的质量，表面光洁度等。更重要的是考虑它的制造难度和成本。所以我们设计应认真分析塑料制品的结构，寻求最佳的设计方案。分型面的选择也很重要，制件不是平直表面，制件的形状很不规则，分型面的选择既要考虑不影响制件表面的美观，又要达到结构要求。由于制品体积比较大，所以浇注系统的设计也很重要，在此次设计中我选顶面侧浇口，并设有冷料穴。拉料杆采用倒锥形，这就解决了制品出模的问题。关键词分型面成型凸模凹模分型面邵阳学院毕业设计（论文）2ABSTRACTTHEMACHINEOFCDTHESHAPEOFTHECOVERTHANFORCOMPLICACY,SOWANTINTHEMOLDINGTOOLDESIGNTHEFACTOROFTHECONSIDERATIONHAVEALOTOF,AMOLD,CENTTYPETHATDIVIDEDBYTHECONSIDERATIONIT,STILLNEEDTHECONSIDERATIONQUANTITYTHATITMODEL,SURFACECLEANANETCMOREIMPORTANTCONSIDERATIONITOFMANUFACTURINGDIFFICULTYWITHCOSTSOOURDESIGNSHOULDANALYZETHECONSTRUCTIONTHATPLASTICSPRODUCTHARD,DESIGNPROJECTLOOKINGFORBESTTHISTIMEDESIGNMOSTAIMSATTHECONSTRUCTIONOFTHEMOLDINGTOOLPROCEEDEDTHEDESIGN,BECAUSECDCOVERCENTERCONTAINACARDDISH,FLANKCONTAINCARDDOOR,SOITMUSTHAVETHESIDETAKEOUTORGANIZATION,BECAUSEOFADOPTINGAMOLDTWOSPACE,SOSIDETAKEOUTCONSTRUCTIONIUSETWOINCLINEDLEADTHEPILLARGUARANTEE,USINGINCLINEDLEADTHEPILLARAROUSETHEINCLINEDSLIPPERYASPORT,EQUIPINGTHEINCLINEDSLIPPERYASMOOTHCENTFOR,FROMBUTGUARANTEEINGMOLDINGTOOLMOLDINFIXEDPOSITIONWITHTHEFIXEDPOSITIONTHECHOICEOFTHECENTTYPEISTOOVERYIMPORTANT,ASHAPEFORISNOTSTRAIGHTANDEVENSURFACE,THEPIECEOFSYSTEMISVERYIRREGULAR,THECHOICEOFTHECENTTYPESINCECONSIDERTODONOTAFFECTASUPERFICIALBEAUTY,ATTAINTHECONSTRUCTIONREQUESTAGAINBECAUSEPRODUCTINGTHEPHYSICALVOLUMEBIGGER,SOSPRINKLETHEDESIGNTHATNOTETHESYSTEMTOOVERYIMPORTANT,HEREADESIGNINSIDEICHOOSEASIDESPRINKLES,ANDESTABLISHTHECOLDANTICIPATINGTHECAVEPULLTOANTICIPATETHEPOLEADOPTIONPOURTHEFORMOFINCLINED,THI
