The floating sand machine generates air flow through a specific mechanism, making the sand grains suspended and evenly distributed inside the equipment. This evenly distributed sand grains helps to form a uniform and dense layer of molding sand on the surface of the parts, thereby improving the quality and surface finish of the castings.

[0003] In a novel floating sand machine disclosed in the existing patent publication number CN216027951U, it includes a machine shell and a cover shell. There is a sand hanging cavity inside the machine shell, and a storage channel communicating with the sand hanging cavity is opened on the cover shell. A scraping plate that fits the bottom surface of the storage channel is slidably connected inside the storage channel; by moving the scraping plate, the bottom surface of the scraping plate moves relative to the bottom surface of the storage channel to scrape the sand on the bottom surface of the storage channel, and the sand falls into the sand hanging cavity as the scraping plate moves, bringing back the sand that has fallen from the wax mold into the sand hanging cavity.
