摘要
Abstract
A new stacked injection mold was designed according to the structural characteristics of the microwave oven in-ner cover.The mold adopts a new product layout,an interflow injection method,and a new lifter structure of hot and cold runners were adopted for the designed mold,resulting in a reduction in the mold cost by 40%and a decrease in the ton-nage of injection machines by 45%.Through using a minimalist action control mechanism instead of the conventional stacked gear and rack action control mechanism,the molding cycle was shortened by 10%.Square guide pillars and guide sleeves were adopted for the mold guiding and positioning system,improving the accuracy and lifespan of the mold greatly.关键词
