The utility model discloses a casting riser structure which comprises a first outer half ring wall and a second outer half ring wall, and relates to the technical field of risers, liquid metal in a molten state is stored in a space formed by two vertical connecting walls, two V-shaped liquid storage walls and two closed connecting walls, and a heat preservation layer plays a role in heat preservation. The V-shaped liquid storage wall equivalently extends into the heat preservation layer, the heat preservation layers attached to the two sides of the V-shaped liquid storage wall have the high temperature through the temperature of the liquid metal in the molten state, and then the temperature is transmitted to the vertical connecting wall; meanwhile, the molten liquid metal in the V-shaped liquid storage wall also plays a role in isolating temperature transfer between the vertical connecting wall and the first outer half ring wall and between the vertical connecting wall and the second outer half ring wall, so that the cooling time of the molten liquid metal in the vertical connecting wall is prolonged, and the heat preservation efficiency is improved; and the situation that the casting effect is poor due to the fact that the cooling speed of liquid metal in the molten state at the riser is too high in the casting process is prevented.
