However, this existing technology cannot reuse the water-cooling liquid, resulting in a significant waste of water resources. Therefore, designing an injection mold for plastic product manufacturing is essential. Utility Model Content

[0005] This utility model is implemented as follows: an injection mold for producing plastic products includes an injection table; a support plate fixedly connected to the bottom of the injection table; a refrigeration box placed on the top of the support plate; a partition plate fixedly connected to the bottom of the refrigeration box; a semiconductor cooling chip body glued to the bottom of the partition plate; a heat conduction frame screwed to the bottom of the semiconductor cooling chip body; a heat dissipation vent in the center of the support plate; a cooling fan screwed into the heat dissipation vent; a pair of drive rods inserted into the refrigeration box; a paddle fixedly connected to the bottom end of each drive rod; a synchronous pulley fixedly connected to the top end of each drive rod; a synchronous belt sleeved between the two synchronous pulleys; a first gear fixedly connected to one of the drive rods; a second gear meshing with one side of the first gear; a motor screwed to the top end face of the support plate; a linkage shaft fixedly connected to the output end of the motor via a coupling; and the end of the linkage shaft away from the motor being screwed and fixed to the second gear.

[0007] Preferably, a pair of mold bodies are provided on the top of the injection molding platform, a pair of slide rails are screwed onto the top end face of the injection molding platform, and the bottom of the mold body is slidably connected to the slide rails. Two electric push rods are symmetrically installed on the top of the injection molding platform, and the telescopic ends of the two electric push rods are respectively screwed and fixed to the outer wall of the two mold bodies.

[0008] Preferably, the top of the mold body is provided with an injection port, and the inside of the mold body is provided with an injection groove, and the injection groove and the injection port are connected to each other.

[0009] Preferably, the mold body has a cooling groove inside, the cooling groove has a heat exchange pipe inside, one side of the cooling groove has an inlet, and the other side of the cooling groove has an outlet.

[0010] Preferably, the two ends of the heat exchange tube are connected to the inlet and the outlet respectively, and the heat exchange tube is in contact with the inner wall of the cooling tank.

[0011] Preferably, a flow pump is screwed onto the refrigeration box, and a branch pipe is inserted into the output end of the flow pump.

The synchronous belt can make the other synchronous pulley rotate synchronously. The synchronous pulley can drive the drive rod to rotate, and the blades can continuously stir the water in the cooling box to promote water temperature balance. This method can reuse the water cooling liquid while ensuring the cooling effect, thus reducing the waste of water resources.

[0014] 2. The movement of the mold body is controlled by an electric push rod, which provides convenience during the injection and demolding processes. In addition, cooling tanks are set inside both mold bodies, which can simultaneously cool the mold while it is cooling, which helps to improve the cooling speed and speed up the work efficiency.
