Abstract
The invention belongs to the technical field of molds, and particularly relates to to a grinding ball red copper water-cooling mold. The grinding ball red copper water-cooling mold comprises a red copper mold body and molding positions, wherein the molding positions are uniformly distributed on the left side and the right side of the front wall of the red copper mold body; a sprue gate is formed in the upper end of the middle part of the front wall of the red copper mold body; a main liquid inlet channel is longitudinally arranged at the middle and lower side of the middle portion of the frontwall of the red copper mold body; a branch liquid inlet channel is horizontally arranged at the lower side of the middle part of the front wall of the red copper mold body; and the bottom end of themain liquid inlet channel communicates with the middle part of the branch liquid inlet channel. The red copper mold body is arranged, so that the cooling effect is good; due to the fact that eighteengrinding balls can be formed at the same time, the efficiency is high; the channels are arranged, air and heat in the molding positions can be quickly dissipated, bubbles can be avoided, raw materialscan enter the channels during forming, and when the size is reduced through cooling, the raw materials in the channels can supplement the molding positions, so that the sufficient raw materials in the molding positions are ensured, and the quality of formed products is guaranteed.
Description
technical field [0001] The invention relates to the technical field of molds, in particular to a red copper water-cooled mold for grinding balls. Background technique [0002] Grinding ball refers to raw materials such as bauxite, roller powder, industrial alumina powder, high-temperature calcined alpha alumina powder, etc., after batching, grinding, powder making (pulping, mud making), forming, drying, firing Made by other processes. A ball stone widely used mainly as a grinding medium. According to different alumina content, it can be divided into medium alumina ball, medium high alumina ball and high alumina ball Medium-high alumina balls, those with more than 90% alumina content are high-alumina balls. [0003] The traditional grinding ball forming mold adopts manual demoulding, which is inefficient, and the supporting grinding ball has air holes, loose density, rough surface, fast wear and easy crushing. Contents of the invention [0004] The object of the present...
