Description

Technical Field

[0001] The utility model relates to the technical field of sand casting, in particular to a sand filling and compacting device for a sand casting mould. 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 simple to manufacture, and it can adapt to single-piece production, batch production and mass production of castings, it has long been the basic process in casting production.

[0003] In some cases where the existing sand casting process requires compaction on both sides of the mold, after completing the compaction of one side, the staff needs to manually turn the sand box over, and then add a new sand box to compact the second layer. The operation is cumbersome and unstable, which slows down the compaction work of the mold. At the same time, after compaction, the excess sand will fall onto the work surface, causing environmental pollution and failing to meet the staff's use needs. Utility Model Content
