Description

Technical Field

[0001] The utility model relates to the technical field of resin sand, in particular to a resin sand block crushing device. Background Art

[0002] Sand casting is a casting method that produces castings in sand molds. Since the molding materials used in sand casting are cheap and easy to obtain, and the mold is easy to manufacture, it can adapt to the single-piece production, batch production and mass production of castings. In order to make the sand mold and the core have a certain strength, it is usually necessary to add synthetic resin to the molding sand to form resin sand. However, a large amount of waste molding sand or core sand will be generated in the resin sand casting process. If the molding sand or core sand is not recycled, it will not only pollute the environment, but also increase the cost of the enterprise.

[0003] There are a lot of block aggregates in the recycled resin sand, which can be reused after being crushed by a crusher. However, the existing resin sand crusher has low crushing efficiency, and the crushed resin sand blocks are of different sizes, which are not convenient for reuse. In addition, dust flies all over the sky when the resin sand blocks are crushed, and the crushing environment is smoky. Therefore, a crushing mechanism of a resin sand regeneration machine is needed.
