Description

Technical Field

[0001] The utility model mainly relates to the field of sand boxes for sand casting, in particular to a sand box for sand casting which can automatically apply paint. Background Art

[0002] Sand casting refers to a casting method that produces castings in sand molds. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting. Since the molding materials used in sand casting are cheap and easy to obtain, the mold is easy to manufacture, and it can adapt to the single-piece production, batch production and mass production of castings, it has long been the basic process in casting production;

[0003] When producing parts through sand casting, sand needs to be placed inside the sand box for shaping, and then the upper and lower sand boxes are attached and molten metal liquid is injected into the inside, and demolding is performed after the metal liquid cools down.

[0004] The inventor discovered the following defects during the operation of the specific embodiment:

[0005] After the sand in the sand box is shaped, a release agent needs to be sprayed on the surface of the sand to quickly separate the parts from the sand. However, manual spraying of the release agent can easily cause uneven application of the release agent, causing the sand to stick to the surface of the part and causing the surface of the part to be uneven.

[0006] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content
