Full mold casting molten iron introducing type chill

Abstract

The invention provides a full mold casting molten iron introducing type chill. The full mold casting molten iron introducing type chill comprises a casting full mold, wherein mold sand of an inner cambered surface of the casting full mold is provided with a plurality of polystyrene foam bars; pig iron is pressed on the middle upper parts of the polystyrene foam bars; the foam bars and a casting model body are in seamless connection, and the foam bars can form iron casting bars after pouring; the polystyrene foam bars have the length of 200-400mm, have the width of 30-100mm, have the thickness of 10-30mm, and are distributed in the mold sand with an oblique array interval of 30-150mm, and the installation oblique angle is 5-45 degrees; the included angle of the inner cambered surface of the casting full mold is 15-120 degrees. By utilizing the full mold casting molten iron introducing type chill, the manufacturing cost of the chill is reduced; the casting defect that a thermal joint of a casting is probably easy to shrink is eliminated; the quality of a casting is ensured. The full mold casting molten iron introducing type chill has the characteristics of low manufacturing cost, simple structure, convenience and reliability in clamping, and good effects.

Description

technical field [0001] The invention relates to a placement method of a full mold casting chill, in particular to a full mold casting molten iron introduction type chill. Background technique [0002] Ordinary casting or general solid casting, in order to eliminate the hot spot of the casting, or reduce the increased heat storage caused by the structure of the casting, and obtain a sound casting without shrinkage and shrinkage, it is necessary to place a chiller, and the chiller is placed using a chiller Put it inside the casting body, that is, the inner chiller, or place it outside the casting body, that is, the outer chiller. However, the complex curved surfaces of automobile molds or other castings need to be machined. It is not allowed to place internal cooling irons, and ordinary external cooling irons are placed on important curved surface shapes of castings, and the cooling effect is often not achieved. There are often shrinkage inside the castings. Loose defects, an...
