The utility model relates to the technical field of die manufacturing. The utility model relates to a casting die, in particular to a rapid-shaping low-pressure casting die. The die comprises an upperdie and a lower die, a feeding hole is fixedly formed in the middle position of the top surface of the upper die; the feeding hole penetrates through the top surface of the upper die and is communicated with the interior of the upper die; symmetrical bolt bases are fixedly welded to the edges of the side faces of the upper die and the lower die. Fastening bolts are arranged on the inner wall of the bolt base in a matched mode, cooling water pipes which are evenly distributed are fixedly laid outside the upper die and the lower die, a temperature transmission filling block is laid between thetwo cooling water pipes, the temperature transmission filling block is fixedly connected to the outer wall of the die through the bolts, and the cooling water pipes are wrapped by a layer of heat insulation shell. According to the utility model, the cooling mechanism is additionally arranged, so that to-be-solidified liquid in the mold can be quickly shaped and solidified, a large amount of waiting time is saved, and the mold is suitable for popularization.
