Horizontally-parted casting ball and casting segment mould

Abstract

The invention discloses a horizontally-parted casting ball and casting segment mould, which comprises a mould body with a parallelly-arranged parting surface. A plurality of model strings are arranged on the parting surface; each model string comprises one or more casting ball and casting segment mould(s); the casting ball and casting segment mould is provided with a pouring port and a feeding head; and the model strings are distributed in a straight-line radiation manner from the center part of the parting surface of the mould body to outside. By the adoption of the technical scheme, sand mould space is reasonably utilized, melted iron is ensured to be rapidly injected into a cavity, the obstacle to melted iron flow is reduced, the volume of a runner of a gating system is greatly reduced, and the casting yield of foundry production is improved, so the production cost is further reduced; and local high temperature during pouring is avoided, normal cooling and solidification of a product are ensured, the casting defects such as high-temperature black heads, high-temperature breakage and the like of the product are overcome, the production quality of the product is ensured, and the qualified rate of the product is improved.

Description

technical field [0001] The invention belongs to the technical field of metal material forming and processing, and relates to technological equipment for casting and forming wear-resistant material media. More specifically, the invention relates to a horizontally split mold for casting balls and casting sections. Background technique [0002] At present, the demand for grinding media used in powder engineering, such as casting balls and casting segments, is increasing, and the product quality requirements are also getting higher and higher. It is required to further improve product quality, increase production capacity and efficiency in the production of casting balls and casting segments, and continuously reduce production costs. [0003] At present, the main problems in the casting technology of casting balls and casting segments are: the yield rate of products is low, the production efficiency is not high, the production cost is difficult to further reduce, and large-scale...

AI Technical Summary

Problems solved by technology

[0003] At present, the main problems in the casting technology of casting balls and casting segments are: the yield rate of the product process is low, the production efficiency is not high, the production cost is difficult to further reduce, and large-scale products are prone to casting defects such as blackheads and shrinkage porosity.

[0006] The volume of the runner similar to the above-mentioned mold is too large, and the utilization rate of molten iron is not very high, that is to say, the process yield rate of the product is not high; Products in high-temperature areas cannot be cooled and solidified quickly and smoothly, and are prone to high-temperature blackheads or defects such as product high-temperature fracture and shrinkage porosity when unpacking
