Description

Technical Field

[0001] The utility model relates to the technical field of metal casting, in particular to a demoulding device for metal casting. Background Art

[0002] Casting is a common metal heat processing technology, which specifically refers to the process of melting metal into a liquid that meets certain requirements and pouring it into a mold. After cooling, solidification and cleaning, a casting with a predetermined shape, size and performance is obtained. Casting is generally sand casting, which uses sand as the mold material. After the metal is formed, the sand shell is demolded to complete the process.

[0003] Generally, when demolding the sand shell on the metal surface, a vibrator is used to remove the large area of ​​sand shell on the metal surface. However, when the vibrator removes the sand shell, a small part of the sand shell will remain on the metal surface and cannot be removed, so the metal product needs to be moved to the next process to perform secondary demolding on the small part of the sand shell remaining on the metal surface. Since the metal product is heavy and needs to be operated by a crane, the work efficiency is low and the process is cumbersome. Therefore, a demolding device for metal casting is proposed to solve the above problems. Utility Model Content
