【Abstract】 This paper introduces iron castings produced by high efficiency mechanized water cold copper alloy metal mold. Systematic researchs on metal mold material, and basic design principle of water cooling copper metal mold and gating system were advanced.Design sand manufactures automobile ductile iron gear in water cold metal mold, and test productes in the production line were carried out. The result shows that liquid iron fill up the mold quietly, and qualified rate achieves 95% of casting, and life excced 10×10 5 times of water cold copper alloy metal mold.更多还原
