Description

Shakeout machine capable of efficiently replacing boards

Technical Field

The utility model relates to the technical field of casting equipment, in particular to a shakeout machine capable of efficiently replacing plates.

Background

Iron mold sand-lined casting is a casting process in which a thin layer of sand is lined in the inner cavity of a metal mold (called iron mold) to form a casting mold. The iron mold sand coating has the characteristics of metal mold and shell mold casting, and as a result, the quality of the casting is greatly improved and the number of waste products is obviously reduced; because the rigidity of the sand-lined iron mold is very high, the dimensional accuracy and compactness of the casting are obviously improved. In the sand-lined iron mold casting process, the coated sand can be dispersed at a high temperature, and can automatically fall off from the inner cavity of the iron mold under the action of self gravity, but the coated sand in the sand injection hole cannot automatically fall off. Therefore, after sand-lined iron mold casting, the residual precoated sand must be manually removed; because the labor intensity in the manual cleaning process is great, a shakeout machine is adopted to clean the precoated sand.

Because the products in the common casting production line are complicated, the positions of sand shooting holes in the iron mold are different, and therefore, higher requirements are put on the universality of equipment. The common shakeout machine can not replace the top plate or has low efficiency of replacing the top plate, and can not meet the current demands. From the above, how to provide a cleaning precoated sand device capable of quickly replacing a top plate, which improves working efficiency and reduces working strength of workers, is a technical problem to be solved by those skilled in the art.
