The company has developed a core tray for heavy-duty wheel casting bottom mold molding and its molding device and process. The core tray contains mutually perpendicular lifting rod bodies and disk bodies. The lifting rod body is a cone with thin upper and thick lower parts, and the lower end of the lifting rod body is connected with the middle of the disk body as a whole; The upper part of the lifting rod body is provided with a transverse through hole. The device comprises a sand box, a bottom basin, a mold base, a lifting template, and the above supporting core plate. A depression matching the disc body is arranged in the middle of the inner surface of the bottom of the bottom basin, and the disc body is installed in the depression. The upper part of the cylindrical surface of the sand box is provided with two opposite notches, which are at the same height with the through hole on the upper part of the lifting rod; The device also contains a wedge rod with a length greater than the diameter of the sand box. The process is the process of making sand mold by using the core tray and its molding device. The invention can greatly improve the yield of the bottom mold, can meet the needs of the production line, and is suitable for the needs of large-scale casting mass and mechanized production.
