[0050] Working principle of the present invention: the staff controls the electric telescopic rod 4 to close the lower mold assembly 3 and the upper mold assembly 6. During the closing process, the lower mold assembly 3 moves upward under the action of the electric telescopic rod 4, thereby driving the conductive tube 302 to move synchronously. When the conductive tube 302 moves to contact the second groove 716, the conductive tube 302 will drive the second groove 716 to continue to move. The movement of the second groove 716 will drive the conductive rod 709 to move, so that the conductive rod 709 can contact the conductive plate 705. Then, when the lower mold assembly 3 and the upper mold assembly 6 complete the closing, the conductive rod 709 can have a larger area to contact the conductive plate 705. When the upper mold assembly 6 and the lower mold assembly 3 are closed, the injection liquid will flow into the upper mold through the injection port 1. Injection molding is performed inside the mold assembly 605, and at the same time, the coolant in the coolant storage tank 5 is opened synchronously, so that part of the coolant can enter the interior of the cooling tank 604 through the liquid inlet pipe 603, and the upper mold 605 is cooled by heat conduction from the interior of the cooling tank 604, and the coolant that absorbs heat flows out of the upper mold assembly 6 through the discharge pipe 602. By maintaining the flow of the coolant in the cooling tank 604, it is ensured that the upper mold 605 can continue to be cooled. In addition, part of the coolant will flow out through the connecting pipe 612 into the interior of the lower mold assembly 3. When the coolant flows inside the connecting pipe 612, the coolant will drive the rotating blade 610 to rotate, and the rotation of the rotating blade 610 will drive the bevel gear through the rotating shaft 609 The bevel gear 1 606 rotates synchronously, and the rotation of the bevel gear 1 606 causes the bevel gear 2 607 to rotate synchronously. When the bevel gear 2 607 rotates, the bevel gear 2 607 drives the gear 2 701 to rotate through the belt, thereby enabling the fan 702 to rotate, generating wind force to dissipate heat to the heat dissipation fins 703, thereby accelerating the cooling effect of the mold, and during the injection molding process, part of the heat in the upper mold 605 is transferred to the conduction plate 705 through the conduction tube 1 611, and part of the heat in the lower mold assembly 3 is transferred to the conduction rod 709 through the conduction tube 302, and then transferred to the conduction plate 705 through the conduction rod 709, and the conduction plate 705 transfers the heat to the heat dissipation fins 703 after absorbing the heat, and dissipates the heat through the wind. The machine 702 continuously blows air to cool the heat sink 703, so that the cooling rate of the device is increased. The coolant flowing out through the discharge pipe 602 will flow into the discharge pipe 307 through the discharge pipe 303, and then flow into the cooling box 201 through the discharge pipe 307. The coolant flowing out through the connecting pipe 612 will flow into the rotating pipe 310 through the flow pipe 308, and then be sprayed into the cooling tank 305 through the spray head 312, so as to cool the inside of the cooling tank 305. The coolant that absorbs heat will flow into the inside of the cooling box 201 through the discharge pipe 307. At the same time, when the coolant flows in the inside of the flow pipe 308, it will drive the gear 311 to rotate through the linkage, and the rotation of the gear 311 will drive the rotating tube 310 to rotate.Then the injection head 312 rotates, so that the coolant can be evenly distributed in the cooling tank 305, thereby accelerating the cooling rate, and the cooling water that absorbs heat in the upper mold assembly 6 and the lower mold assembly 3 will flow into the cooling box 201, where it will be collected and cooled. When the cooling process is completed and the mold is separated and the material is unloaded, the conduction pipe 302 will drive the groove 712 to move downward, so that the conduction rod 715 can be inserted into the cooling box 201 with a larger area, and the conduction rod 715 is cooled by the residual coolant in the cooling box 201, so that the temperature in the lower mold assembly 3 can be further reduced, and the water pump will transfer the water in the cooling box 201 to the coolant storage tank 5, so that the cooling water in the device can be recycled, and by increasing the movement path of the coolant, the cooling time of the coolant is increased, so that the recycled coolant can meet the cooling requirements.
