Background

Sand casting is a casting process that produces castings in sand molds. Steel, iron and most nonferrous metal castings can be obtained by sand casting. In order to make the sand mould and core have certain strength and not deform or damage when carrying, assembling and pouring liquid metal, a sand binder is generally added in the casting process to bind loose sand grains to form the molding sand. The currently common binder used for chemically hardened molding sand is synthetic resin, water glass, or the like. The surface contour of a casting produced by the resin sand molding process is clear and smooth, and the geometric precision and the dimensional precision are high; the production process is simple and easy to control, and is more and more accepted and applied by casting enterprises.

Most of the existing resin sand casting molding feeding devices utilize a spiral feeding paddle to feed materials and then guide the materials out through a material guide bag, but the existing material guide bag needs to be manually held by hands to assist in bag shaking so that the resin sand is guided into a molding die more easily and needs to move along with the material guide bag, so that the fatigue strength of workers is high, and the resin sand casting molding feeding devices are not suitable for efficient production; meanwhile, the length of the guide bag is limited, and the guide bag cannot go deep into the molding mold aiming at the molding molds with different depths, so that when resin sand is poured, the problem that the resin sand is poured into the molding mold is easy to occur.
