挂式空调前盖的注塑模设计 摘要 和传统注塑模具设计方法相比，基于proe和Moldflow的注塑模具设计的设计周期短，成本低并且模具制造工艺性能好。本次设计的零件是挂式空调前盖。首先用计算机辅助软件proe来进行零件的三维造型和注塑模具设计。对设计的零件进行结构与工艺分析，注塑模具设计成三板模，一模一腔，单流道，斜导柱抽芯机构和斜顶抽芯机构，摆钩分型螺钉定距机构。设计成型零部件以及设计合理的推出机构。对设计进行验证主要是对注射机的相关重要参数进行验证，包括模具闭合厚度、模具安装尺寸、模具开模行程、注射机的锁模力等。在校验合格后，进行成型零件加工工艺过程的制定，既要保证塑件的质量，又要兼顾经济性。最后则是模具的装配环节，包括制定装配步骤、明确注意事项等。模具出图环节将使用AutoCAD对装配图和零件图进行修整。然后采用模流分析软件Moldflow对零件进行最佳浇口位置分析和充填+冷却+翘曲分析，根据分析结果对冷却系统和浇注系统进行调整和优化，注塑模具中的浇注系统和冷却系统也进行相应的调整。 最后的注塑模具浇注系统合理，流料能够完全充填型腔；冷却系统的冷却效果良好；制品翘曲程度达到合理的范围；模具整体结构合理。 关键词：空调前盖；proe；Moldflow；注塑模具 Abstract Comparedwith the traditio
