Foundry Process Improvement for ZL101A Mechanism Box Casting and Its Metal Mould Design
Based on the integrated analysis of the structure of ZL101A alloy mechanism box,the present sand casting method for mechanism box castings exists the problems of low density,high surface roughness and low productivity.In this paper the metal casting process was employed and a set of metal mold was designed including casting drawing design,the metal mold design and the sand core box design.Results show that as metal mold cools quickly and the condition of casting is stable,castings with dense structure,good dimensional accuracy and fine surface roughness,were obtained at the same time with greatly improved production efficiency.
