Device and method for cleaning iron mold in sand faced iron mold casting production

Abstract

The invention discloses a device and a method for cleaning an iron mold in sand faced iron mold casting production. The device comprises an ejection cylinder body, an ejection plate, ejector rods, iron mold conveying roller beds, a sand shakeout hopper device and a frame, and is characterized by being provided with a vibration device, wherein the ejection cylinder body is fixed on an upper beam of the frame; a piston rod of the ejection cylinder body is fixedly connected with the ejection plate; the ejector rods are arranged on the ejection plate; the positions and number of the ejector rods correspond to those of sand ejection holes on the iron mold; the iron mold conveying roller beds are fixedly arranged on the ejection plate; an iron mold positioning device is arranged in the middle of the iron mold conveying roller beds; the vibration device is fixed on a base of the frame; and the sand shakeout hopper device is fixed on the vibration device and is positioned under the ejection plate. Certain ejection pressure is applied to residual sand in the sand ejection holes of the iron mold through the ejection cylinder body, and certain vibration force is applied to the iron mold so as to vibrate the iron mold; and finally, the sand ejection holes of the iron mold are ejected to be through, and the residual sand in an inner cavity of the iron mold is cleared up.

Description

technical field [0001] The invention relates to a device and method for cleaning iron molds in iron mold sand-covered casting production. Background technique [0002] Sand-covered iron casting is one of the special castings. The casting mold is formed by covering the inner cavity of a metal mold with a thin layer of coated sand. The metal mold is called an iron mold. In the production process of sand-covered iron mold casting, the sand-coated layer on the iron mold is covered by the sand-shooting molding machine on the inner cavity of the iron mold through the sand-shooting holes of the iron mold. After the molten iron is poured, there is still a considerable part of the residual sand in the inner cavity of the iron mold and the sand shooting hole that has not collapsed and remains in the iron mold. In this way, when the next iron mold is sand-covered, the residual sand must be removed. The residual sand cleaning of iron mold sand-covered casting iron mold includes: clean...

AI Technical Summary

Problems solved by technology

The defect and deficiency of the above-mentioned technical solution is that the shock force of this cleaning method is small, the workpiece to be cleaned is generally small, and the sand-covered sand in the iron-shaped sand shooting hole cannot be cleaned.
