AI Technical Summary
Technical Problem
The existing iron-molded steel ball casting molds have low quality and efficiency when casting steel balls, and are not high enough in density and poor uniformity.
Method used
The upper and lower molds are made separately, and cast steel balls are cast by mold clamping. The inner and outer molds are equipped with insulation column cavity, inner cavity and outer cavity to ensure that the molten iron is maintained for a longer time at high temperatures, fully absorbing the molten iron, and increasing the density of the steel balls.
Benefits of technology
It improves the density and uniformity of the steel ball, enhances casting efficiency, reduces mold deformation, and extends the service life of the mold.

Abstract
The invention provides an iron mold sand-coated steel ball casting mold, belongs to the technical field of sand-coated steel ball molds, overcomes the technical defects of low steel ball casting quality and low efficiency of an existing sand-coated steel ball mold, comprises an upper mold and a lower mold for manufacturing steel balls, and is characterized in that a steel ball cavity comprises an inner cavity and an outer cavity; the inner cavities and the outer cavities are the same in radius, the inner cavities are evenly arranged around the circumference of the heat preservation column cavity, and one outer cavity is arranged between every two inner cavities on the outer ring of the inner cavities, and the sphere center distance between the outer cavity and the inner cavity on the right side in the mold is smaller than the sum of the radiuses of the two cavities. The sphere center distance between the outer cavity and the inner cavity on the left side is larger than the sum of the radiuses of the two cavities, molten iron can be kept for a longer time at the high temperature, the molten iron can be absorbed more sufficiently, the density of the sphere is guaranteed, the product quality is improved, and the service life of the mold is prolonged. The sand-coated layer is convenient to demould; and the rough surface can increase the adsorption force, so that the mold is convenient to transport and pour.
