某型号空调百叶注塑模具设计 摘要 模具技术是一项非常关键的产业，为国家经济发展做出巨大的贡献，并且在国际上，模具处于工业当中领先地位，受到的重视度非常高，近些年来模具工艺不断趋于成熟，且国家对于模具的研发以及设计都比较重视。由于模具覆盖的产业比较广泛，产值也非常高，特别是在重工业以及汽车制造，制造业跟医疗等行业，各类产品的制造都离不开模具的支持，尤其是人们生活周边各种产品都是模具产品，通过数据显示，目前全球一半以上产品都是需要模具加工出来，而且模具加工产品可以实现大批量加工，因此在经济上有比较大的优势，因此市场越来越好。 本次设计的空调百叶塑料模具，这种空调百叶属于较为常见的塑件，选用经济性和性能比较好的PA66材料，设计需要对产品做出分析，选取产品的分型面，并且对型腔的数目做出选取，并且通过计算选定满足要求的注射机设备，对成型零件做出尺寸计算以及模具图纸绘制要求。 关键词：注塑模具；工艺分析；空调百叶 Abstract Mold tech
