Iron-typed cast ball die

Abstract

The invention discloses an iron-typed cast ball die which comprises two separated die bodies, wherein a junction surface of the two separated die bodies forms a die parting surface; model cavities of a cast ball are arranged on the die parting surface; a cast ball die is provided with a pouring gate, a plurality of cross gates and inner pressing feeder head cavities with the quantity the same as that of the cross gates; the outer end part of each cross gate is provided with a group of model cavities; and the model cavities are connected with the cross gates through the inner pressing feeder head cavities. According to the technical scheme, the iron molding cast ball die is widely applied to manual operation, or mechanical and automatic continuous casting production lines in the production of iron-typed cast balls, expands the pouring and molding capacity of individual dies for each batch, and meets the productivity requirement of each kind of production mode; and the situation that metal liquids overflow caused by box lifting in casting and pouring is prevented, the production condensation molding quality is improved, casting defects of black heads, shrinkage porosity and the like for cast products are prevented, the damage to the die by metal liquids is prevented, the service life of the die is prolonged, and the production safety is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of forming and processing of metal materials, and relates to technological equipment for casting and forming of wear-resistant material media. More specifically, the present invention relates to an iron mold for casting balls. The invention is equally applicable to the production of cast sections. Background technique [0002] It has been used for more than 30 years in the production of iron molds for the production of wear-resistant cast balls and segment products. But, in prior art, there is defect in this iron mold, and its main problem is: [0003] The production capacity of a single pair of molds is low, which is only suitable for manual production and not suitable for mechanized operations; during the casting production process of existing molds, molten metal often overflows, which directly poses a threat to personal safety; the overflow of molten metal directly leads to the casting of the product d...
