The utility model provides an ingot mold. The ingot mold comprises an ingot mold body and lifting lugs, wherein the lifting lugs are symmetrically arranged on the outer walls of the two sides of the ingot mold body, the ingot mold body is provided with an inner cavity and an upper opening connected with the inner cavity, the inner cavity is of a big-end-up conical structure, the cross section of the inner cavity is a rounded square, and the longitudinal section of the inner cavity is trapezoidal. A dead head is arranged at the upper end of the upper head and is of a groove structure; a die bottom hole is formed in the bottom of the ingot die body and connected with the inner cavity. The steel ingot mold is cast by low-carbon steel; the cast steel ingot mold has the characteristics of hightemperature resistance, shock cooling and shock heating resistance, high toughness, no phase change and the like; besides, the inner cavity of the ingot mold body is of the big-end-up conical structure, the ingot mold of the structure can prevent molten steel from scouring the mold wall, cracks generated in the cooling process of the ingot are reduced, smooth demolding of the ingot can be guaranteed, the quality of the ingot mold manufactured after high-temperature normalizing heat treatment is stable, and the service life of the ingot mold is prolonged.
