When the injection mold is cooled, the injection mold is placed in the mold groove 301, and water just covering the second heat sink 302 is added to the cooling groove 102. When the injection mold is cooled, the power is turned on, and the heat is quickly transferred from the injection mold through the second heat sink 302 to the water flow to cool the injection mold. The water flow enters the groove 303, which increases the contact between the injection mold and the water flow, making the heat dissipation of the injection mold more uniform and rapid. The multiple groups of annular first heat sinks 304 also accelerate the heat dissipation speed of the injection mold. The injection mold is cooled from three angles: bottom, side, and top, so that the heat dissipation area is increased, the heat dissipation speed is accelerated, the heat dissipation is uniform, and the quality of plastic forming is guaranteed.

[0024] Furthermore, a heat dissipation cavity 103 is provided on the side of the main body 1 and at the bottom of the first heat sink 304, and a first fan 5 is provided inside the heat dissipation cavity 103. When the injection mold is cooled, the power is turned on, and the first fan 5 in the heat dissipation cavity 103 blows air to the multiple groups of first heat sinks 304 for heat dissipation, thereby accelerating the heat dissipation speed of the injection mold.

[0025] Among them, a water outlet 101 is opened on the side of the main body 1 and located at the top of the heat dissipation cavity 103, and used waste water flows out from the water outlet 101. An air outlet 104 is opened at the bottom of the heat dissipation cavity 103 and located on the side of the main body 1. The first fan 5 draws cold air from the air outlet 104 and blows it toward the multiple groups of first heat sinks 304 in the heat dissipation cavity 103, thereby accelerating the heat dissipation speed of the injection mold.

The quality of plastic forming is guaranteed, and the heat dissipation speed is accelerated. The second fan 501 draws cold air from the air outlet 601 and blows it toward the injection mold, which accelerates the heat dissipation speed of the injection mold. The first fan 5 draws cold air from the air outlet 104 and blows it toward the multiple groups of first heat sinks 304 in the heat dissipation cavity 103, which accelerates the heat dissipation speed of the injection mold. The device dissipates heat from the injection mold from three angles: bottom, side, and top, so that the heat dissipation area is increased, the heat dissipation speed is accelerated, the heat dissipation is uniform, and the quality of plastic forming is guaranteed.
