Description

Technical Field

[0001] The utility model relates to the technical field of floating sand machines, in particular to a shell making floating sand machine. Background Art

[0002] Shell making is a key step in the precision casting process. Its main purpose is to create a shaped cavity during the metal casting process so that molten metal can be poured into it to produce a casting of the desired shape.

[0003] During the manufacturing process, the shell will form a fire-resistant layer by setting a coating layer and a sand layer. The existing Chinese patent with the authorization announcement number CN217941777U discloses an automatic sand filtering floating sand machine. It includes a sand screening and filtering device and a smoke and dust treatment device. The smoke and dust treatment device set on the upper part of the shell collects and treats the smoke and dust to avoid pollution to the production environment and the external natural environment.

[0004] Since the sand layer is sprayed on the surface of the coating layer by a sand spraying machine, there will be some sticky floating sand and impurities on the surface of the coating layer. In order to ensure the smoothness and fire resistance of the shell, the floating sand and impurities on the surface are usually peeled off by a floating sand machine. The separation of floating sand and impurities is usually achieved by vibration or airflow, but due to the limitation of the shell template, when the shell is vibrated alone, the floating sand on the inside of the shell is prone to secondary adhesion with the coating on the surface of the shell, and some floating sand and impurities still remain on the inside of the shell, affecting the fire resistance of the shell. Utility Model Content

[0005] In view of the above-mentioned existing limitations of the shell template, when the shell is vibrated alone, the floating sand inside the shell is prone to secondary adhesion with the coating on the surface of the shell, and some floating sand and impurities still remain inside the shell, affecting the fire resistance of the shell, the present utility model is proposed.
