Cast grinding ball metal mold is used to produce cast grinding ball manually. Grinding ball die casting mold can produce grinding balls from φ20mm to φ140mm. Steel grinding media ball mold can for a long time.
Made of special metal materials, the mold is used to produce balls with the chilling forming technology. The surface of the product is smooth, slick and the grains on which are evenly distributed. Its rigidity is significantly improved and the core and surface are basically of the same rigidity, thus, enhancing its comprehensive physical performance and abrasion-resistant performance. The mold is easy to be operated. In addition, it is replaceable between the mold of the same specifications, therefore, if the ball core of the assembling mold is worn, it can be replaced, usually for 5～10 times. After the ball core is changed, the operational effect of the mold is as good as the new one, thus, greatly reducing the use cost of the mold.
Products made by this series of mold have the following attributes: the product is free from distortion, forging defects and has high melted iron use efficiency, high technological yield, and long service life. Optimization and upgrading can thoroughly solve the exhaust problems in the operational process to avoid the occurrence of such phenomena as slippage and cold shut etc. Up to now, it is the best replacement of single mold, disposable mold, and sand forging mold.
