Since the molding materials used in sand casting are cheap and easy to obtain, and the mold is simple to manufacture, it can adapt to the single-piece production, batch production and mass production of castings.

[0003] The existing casting generally places a mold at the bottom of two casting boxes, and then fills the casting boxes with casting sand so that the casting sand is spread flat in the casting boxes, and then presses the casting sand so that the bottom of the casting sand has a cavity with the same shape as the mold, and then hoists the two casting boxes, and makes the two casting boxes fit together with one side of the mold cavity to form a casting cavity for the product, and then hoists the casting boxes to the position where the casting work is performed, waiting for casting. In the prior art, the method of spreading the casting sand in the casting box is as follows: the discharge port of the hopper at the top is opened, and the casting sand falls into the casting box under the action of gravity. After a certain amount of casting sand falls, the discharge port is closed. At this time, the casting sand mainly falls to the middle of the casting box, and then it is necessary to manually distribute the casting sand evenly around and spread it flat, and the work efficiency is low.
