After passing through all the auxiliary frames 793, it will enter the cooling pipe 795, and dissipate the heat through the longer pipeline flow of the cooling pipe 795, and finally flow back into the box 71, so as to achieve the purpose of circulating heat dissipation. In the above process of coolant flow, the fan 782 can work to further cool the cooling pipe 795 and the heat sink 799, so as to improve the heat dissipation efficiency and accelerate the cooling and molding of the injection molded parts. After the injection molded part is cooled and formed, the first electric push rod 787 first works to push the movable plate 786, and the movable plate 786 drives the bellows 797 to contract, so that the suction port at the bottom of the bellows 797 is higher than the liquid level. As the pump body continues to work, the coolant in the circulation process can be sucked into the box body 71 to avoid the coolant residue causing the coolant to flow out during subsequent demolding. Then, the above operation is repeated to move the punch 4 to the top of the die 3, which is a distance sufficient for the injection molded part to be demolded. After that, the second electric push rod 97 works to push the square plate. The shaped plate drives the movable plate 96 to move, the movable plate 96 drives the rack to move, and the rack moves and drives the gear 95 to rotate, and the gear 95 drives the threaded adjustment rod 93 to rotate. After the threaded adjustment rod 93 rotates, it can drive the platform plate 91 to move up and down. When the platform plate 91 rises, it drives the ejector rod 92 to move upward. At this time, the ejector rod 92 can eject the injection molded part, so as to achieve the purpose of rapid demoulding. When the demoulding is completed, the platform plate 91 moves down to the bottom and fits the support block 94. The support block 94 can provide bottom support for the platform plate 91, thereby improving the stability of the platform plate 91 when it is idle.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
