description	The utility model provides an improved metal type cast ball mould, which is mainly composed of an upper mould, a lower mould and a hot dozzle. The utility model is characterized in that an oblique pouring channel with an angle of 30-60 DEG and a reusable and detachable hot dozzle are adopted to enhance the feeding effect of molten iron. The quality of the grinding balls is stabilized and enhanced. A plurality of grinding balls can be cast in one step due to the design of the utility model so as to enhance the production efficiency. Environment pollution is avoided because the hot dozzle is not made from mould sand.
