The company has developed a mold for casting train wheels, including a lower mold and an upper mold. The lower mold includes a lower graphite mold, a lower top plate and a lower sleeve box. The upper mold includes an upper graphite mold, an upper top cover and an upper sleeve box. The inner side of the lower graphite mold is sprayed with a lower sand lining, the inner side of the upper graphite mold is sprayed with an upper sand lining, and the inner surface of the lower graphite mold and the inner surface of the upper graphite mold form the rim and tread surface of the casting cavity of the train wheel, The inner surface of the lower sand lining and the inner surface of the upper sand lining form the plate and hub surface of the casting cavity of the train wheel; The upper part of the upper mold is provided with a riser, which is composed of an upper sand liner. An easy to cut riser sheet is arranged at the junction of the riser and the casting cavity of the train wheel. A feeding channel is arranged in the middle of the easy to cut riser sheet. A plug rod assembly is inserted in the feeding channel. The lower end of the plug rod assembly is connected with a plug head, which is correspondingly provided with a molten steel channel, which is arranged on the lower mold. The wheel rim produced by this mold has uniform structure, no petal phenomenon, good product quality and low scrap rate.
