Description

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

[0003] During the casting production process, the upper mold of the sand box is placed with the front side facing upwards. When the mold is placed in the sand box, the upper mold needs to be flipped 180°, that is, facing downwards, so that it can be combined with the lower mold of the sand box for pouring.
