Embodiment Construction
[0025] The present invention is not limited by the following examples, and the specific implementation manner can be determined according to the above-mentioned technical solutions and actual conditions of the present invention.
[0026] Below in conjunction with preferred embodiment and accompanying drawing, the present invention will be further described:
[0027] The vacuum sealing method for producing grinding balls is carried out in the following steps:
[0028] The first step is to extract air from the lower mold box of the ball mold, and then cover the mold surface of the lower mold box of the ball mold with a film, then place the lower box of the ball tool on the lower mold box of the ball mold, Fill sand in the lower box of the tooling and vibrate it, cover the surface of the lower box of the vibration ball tooling with a backing film and pump air, and finally pull out the mold to get the lower model of the ball;
[0029] In the same way, the upper mold box of the gr...

A vacuum-sealed method for producing grinding balls and its forming mold. In the method, air is firstly pumped and covered with a film, filled with sand, vibrated, covered with a back film and pumped, and the mold is lifted to obtain the lower model of the grinding ball and the upper model of the grinding ball respectively. ; followed by boxing to form a grinding ball model cavity; finally casting, cooling, and mold removal to obtain formed grinding balls. The characteristics of the present invention are: the vacuum-sealed method for producing grinding balls can greatly improve production efficiency, the production efficiency of a single box can be increased several times, the process yield can reach 95%, the reject rate can be greatly reduced, and mechanized production can also be realized; The ball forming mold has a reasonable structure and is easy to operate.
Description
technical field [0001] The invention relates to a method for producing grinding balls, which is a vacuum-sealed production method for grinding balls, which is especially suitable for producing grinding balls for ball mills. Background technique [0002] Existing methods for producing grinding balls mainly adopt molding methods such as metal molding and green sand molding. Green sand molding and metal molding can only produce 3-5 balls per box, the main process is manual operation, the process yield is below 70%, many people are invested, the controllability of the process is poor, the labor intensity is high, and the production efficiency is high. Low, high scrap rate. Contents of the invention [0003] The invention provides a vacuum-sealed method for producing grinding balls, which greatly improves production efficiency and yield, and greatly reduces the reject rate. [0004] The present invention also provides a grinding ball forming mold used in the above-mentioned v...
