[0038] Working principle:

[0039] After the raw material is injected into the interior of the upper mold 2 through the injection cavity 10, the circulation pump 4 is started, so that the circulation pump 4 injects the coolant into the interior of the lower mold 2 through the pipe 3 on the left, and then the coolant is sent to the pipe 3 inside the ventilation hole 5 of the base 1 through the pipe 3 on the right, and then the fan 6 is started, so that the fan 6 draws the cold air from the outside into the interior of the base 1, and the cold air contacts the right pipe 3 and performs heat exchange, so that the coolant is cooled and then discharged into the interior of the lower mold 2 again, so that the lower mold 2 and the upper mold 7 perform heat exchange on the coolant, so that the raw material can be cooled quickly. When the raw material is cooled, the workpiece is formed, and the upper mold 7 is moved up by the electric cylinder 9, so that the top of the vertical block 801 inside the upper mold contacts the top plate 11, and then continues to move up, so that the top plate 11 pushes the vertical rod 801 down, and then the top block 802 pushes the workpiece out, thereby facilitating the demoulding of the workpiece.
