Sprue cup device and pouring method for iron mold sand-covered casting

Abstract

The invention relates to a sprue cup device and pouring method for iron mold sand-covered casting, which are applied to molten iron pouring in casting production, and belong to the field of iron mold sand-covered casting equipment tooling. The sprue cup device in the present invention comprises a sprue cup upper iron mold, a sprue cup resin sand mold and a sprue ceramic filter net, the sprue cup upper iron mold is a trumpet type, the sprue cup resin sand mold and the sprue cup upper iron mold Cooperating with each other, the iron mold on the upper part of the sprue cup is located above the resin sand mold of the sprue cup, and there is a sprue ceramic filter net inside the iron mold on the upper part of the sprue cup. The invention solves the casting defects caused by the gating system. The sprue cup has the function of filtering the molten iron and has a good liquid feeding effect on the molten iron in the mold. The cleaning operation of the gate is simple and convenient during the production process. The trumpet shape of the iron mold on the upper part of the cup can be reused repeatedly, which saves the cost of making the sprue cup, and the pouring method is simple and reasonable, which meets the needs of people.

Description

technical field [0001] The invention relates to a device and a method, in particular to a sprue cup device and a pouring method for sand-coated iron casting, which are applied to molten iron pouring in casting production, and belong to the field of sand-coated casting equipment for iron molds. Background technique [0002] Iron mold sand-coated casting is one of the special castings. The mold is formed by covering the inner cavity of the metal mold with a thin layer of coated sand. Compared with ordinary sand casting, the pouring system of iron mold sand-covered casting is relatively small, which can realize casting without riser, and the yield of molten iron is high. It is precisely because of this characteristic of iron mold sand-covered casting that the casting During the filling process of molten iron, the ability of the gating system to filter and retain slag is far inferior to that of ordinary sand casting.
