Description

Technical Field

[0001] This invention belongs to the technical field of casting auxiliary equipment, and relates to a tilting device for casting sand boxes. Background Technology

[0002] Sand boxes are commonly used equipment in the casting industry. During processing, the mold is first placed inside the sand box, then sand is filled into the sand box and vibrated to press the sand. When the mold and the sand box are separated, a cavity will be formed between the molding sand inside the sand box and the surface of the mold. The sand box needs to be turned over before the subsequent pouring process can begin.

[0003] In the casting process, the upper mold of the sand box is placed face up. When the mold is placed in the sand box, the upper mold needs to be rotated 180° so that face down so that it can be closed with the lower mold of the sand box before casting. Currently, the upper mold is rotated manually with the help of simple tools. Because the upper mold of the sand box is generally quite heavy, it is very difficult to rotate, resulting in high labor intensity and low production efficiency for workers.
