文档介绍：摘要以手机后壳注塑模具设计为例,介绍了注塑模具的设计方法和流程。首先根据塑件材料及工艺特性用MOLDFLOW软件对零件进行模流分析,然后选择注塑机并确定型腔数目,接着确定成形方案:总体结构设计、分型面设计、浇注系统设计、脱模机构设计、冷却系统设计等。最后进行注塑机工艺参数校核,包括注射量、锁模力、注射压力、模具厚度和注射机闭合高度等方面。该设计方法对其它不同结构产品的注塑模具设计有一定的参考价值。关键词:结构,模流分析,模具AbstractTocoverofthephonecasemolddesign,,ponentsforuseMOLDFLOWmoldflowanalysis,hecavity,andthenformingtheprogramtodetermine:theoverallstructuraldesign,sub-surfacedesign,castingdesign,moldreleasemechanismdesign,,injectionmoldingmachineparameterschecked,includingtheinjectionvolume,clampingforce,injectionpressure,:structure,moldflowanalysis,mold目录第一章调研报告..............................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................2第二章产品工艺分析..............................................................................................................................................................................................................................................................................................................3第三章模具结构设计与参数计算.................................................................................................................................................................................................................................................................................
