Abstract

The invention discloses a grinding ball casting mould, which comprises a template, a composite pouring gate module, more than four branch pouring gate modules and hemispherical die bodies, wherein the composite pouring gate module is positioned on the middle part of one side surface of the template; the branch pouring gate modules are symmetrically embedded on two sides of the composite pouring gate module; the other ends of the branch pouring gate modules are connected with the hemispherical die bodies; the head of each hemispherical die body is in a semi-ball shape; the tail end of each hemispherical die body is provided with a cylindrical positioning boss; the positioning bosses of the hemispherical die bodies are embedded onto the template and are fixed by bolts; and two sides of the template are respectively provided with guide holes. The grinding ball casting mould disclosed by the invention has wide applicability and is suitable for continuously producing and manufacturing casting grinding balls of various specifications of phi60-150mm by vertical parting and flaskless casting. Compared with the production rate in the prior art, the production rate of the grinding ball casting mould is improved by about two times; the axis of the hemispherical die body strings and a horizontal line are in downward-inclination arrangement of 6-25 degrees; the casting and forming technology is scientific and reasonable; mismatch and box emission are avoided; and the rate of certified products is improved by 20%.

Description

technical field [0001] The invention relates to a ball casting mold. Background technique [0002] Grinding ball is a special metal grinding medium for ball mill widely used in powder engineering in mining metallurgy, thermal power energy, cement building materials, construction machinery and other industries. In order to improve the wear resistance and production efficiency of ball mill balls, Chinese patent 200710023997.2 discloses a multi-row series cast grinding ball casting pattern, which is characterized in that there are more than two vertical sprue modules on the pattern plate, vertical The sprue module is composed of hemispherical blocks and semi-cylindrical blocks arranged staggeredly. The two sides of the hemispherical block are respectively connected with the hemispherical pattern string formed by the coaxial series connection of more than three hemispherical patterns. The cylindrical thin plate forms a connected casting channel, and the angle between the axis ...
