The point type straight water-cooling hub mold shown in fig. 1-3 comprises side molds 1 distributed in an annular shape and a cavity 2 formed by the side molds 1 in a surrounding mode, wherein the cavity 2 in the side molds 1 is used for casting a hub. The integral side die consists of a plurality of split side dies 1, and the side dies 1 of adjacent split bodies are connected to form an annular integral side die. A plurality of through holes 21 communicated with the cavity 2 are formed in the outer side wall of the side die 1, a cooling rod 22 is fixedly arranged in each through hole 21, and the cooling rod 22 is connected with the water cooling device 3. Preferably, the water cooling devices 3 on the side die 1 are distributed circumferentially, that is, the water cooling devices 3 are arranged around the die cavity 2, so that multi-point water cooling can be performed on the hub cast in the die cavity 2, and the cooling effect is good. The water cooling device 3 comprises a clamping sleeve joint 31 and a discharge pipe 32 in sealed clamping connection with the clamping sleeve joint 31, an input pipe 33 is sleeved in the discharge pipe 32, and a discharge channel 34 is formed between the discharge pipe 32 and the input pipe 33.
