我厂有很多套薄壁深腔压铸模或局部薄壁深腔压铸模,在薄壁端部加设条带间隙后其成型性都大大提高。如我厂生产的50型摩托车上的右曲轴箱体(材料ZL111)是一个较复杂的薄壁深腔压铸件,未改进前成品率只有60％～65％,经改进后成品率增至88～94％,经济效益提高了将近一倍。图为右曲轴箱体压铸模的条带间隙排气槽结构简图。表为几种有色合金的条带间隙尺寸。
I plant a lot of sets of thin-walled deep cavity die-casting mold or partial thin-walled deep cavity die-casting mold, in the thin-walled end of the strip gap after the addition of its formability are greatly enhanced. For example, the right crankshaft box (material ZL111) on the 50 motorcycle produced by our factory is a more complex thin-walled deep cavity die-casting with a yield of 60% -65% without improvement. The yield of finished products has been increased to 88 ~ 94%, economic efficiency has nearly doubled. The picture shows the structure of the exhaust gap of the strip gap of the right crankcase die-casting mold. Table for several non-ferrous alloy strip gap size.
