Technical Field

[0001] The utility model relates to the technical field of demoulding devices, in particular to a demoulding device for a sand casting mold which can prevent damage. Background Art

[0002] Sand casting molds are made of sand. Sand casting requires placing a finished part model or a wooden model in the sand, then filling the area around the model with sand to shape it. After the model is taken out of the box, the sand forms a mold, and then the metal liquid is injected into the sand mold to form the mold through the sand.
