A water inlet pipe 203 connected to the water flow cavity 202 is installed on the right side of the lower mold shell 2, and a water outlet pipe 204 connected to the water flow cavity 202 is arranged on the left side of the lower mold shell 2. The water inlet pipe 203 is connected to the water cooling mechanism 6, and the water cooling mechanism 6 is connected to an external water source. The frame 3 is fixed on the base 1, and a pressing mechanism 4 is installed on the frame 3 just above the lower mold shell 2. Mechanism 4, the front side of the lower mold shell 2 is equipped with an air cooling mechanism 5 on the base 1. When in use, the pressing mechanism 4 is first pressed onto the lower mold shell 2, and then, the high-temperature molten material is injected into the molding groove 201. At the same time, the external water source connected to the water cooling mechanism 6 is opened, and the water flow is cooled by the water cooling mechanism 6. Cold water enters the water flow cavity 202 from the water inlet pipe 203, and the heat on the molding groove 201 is taken away by the cold water, thereby cooling the material in the molding groove 201. When the material is cooled and formed, the pressing mechanism 4 is moved up to separate it from the lower mold shell 2, and then the air cooling mechanism 5 is rotated to the top of the molding groove 201, and air is blown into the molding groove 201 through the air cooling mechanism 5, thereby accelerating the cooling speed of the material and reducing the waiting time for cooling.

The pressing mechanism 4 includes: a hydraulic cylinder 401 , an upper die head 402 and an injection hole 403 . The hydraulic cylinder 401 is fixed on the frame 3 . The lower end of the hydraulic cylinder 401 is connected to the upper die head 402 . The upper die head 402 is provided with an injection hole 403 .

The air cooling mechanism 5 includes: a driving motor 501, a first gear 502, a second gear 503, a support shaft 504, a top plate 505 and a fan 506. The driving motor 501 is fixed on the base 1. The output shaft of the driving motor 501 is equipped with a first gear 502. A second gear 503 is installed on one side of the first gear 502 to rotate with it. The second gear 503 is installed on the support shaft 504. The bottom of the support shaft 504 is rotatably connected to the base 1. The top of the support shaft 504 is connected to the top plate 505. The plates 505 are fixed to each other, and a fan 506 is installed on the lower side of the top plate 505. When in use, the first gear 502 and the second gear 503 are driven to rotate by the driving motor 501, and the support shaft 504 and the top plate 505 are driven to rotate by the second gear 503. The fan 506 is driven by the top plate 505 to rotate above the molding groove 201, and air is blown toward the molding groove 201 by the fan 506, thereby accelerating the cooling speed of the material in the molding groove 201.

A plurality of semiconductor refrigeration plates 602 are installed on the outside of the spiral tube 601. The spiral tube 601 is made of copper, so that it has good thermal conductivity. The spiral design of the spiral tube 601 can increase the circulation time of the water in the spiral tube 601. When in use, the external water passes through the spiral tube 601 and enters the water inlet pipe 203. The water flowing in the spiral tube 601 is cooled and cooled by the semiconductor refrigeration plate 602, thereby reducing the temperature of the water and improving the cooling and heat absorption effect of the water.

The working principle of the utility model is as follows: when the injection mold with cooling function is used, the upper die head 402 is first driven by the hydraulic cylinder 401 to be pressed onto the lower mold shell 2, and then the high-temperature molten material is injected into the molding groove 201. At the same time, the external water flows through the spiral tube 601 into the water inlet pipe 203, and the water flowing in the spiral tube 601 is cooled and cooled by the semiconductor refrigeration sheet 602, thereby reducing the temperature of the water flow. The cold water enters the water flow cavity 202 from the water inlet pipe 203, and the heat on the molding groove 201 is taken away by the cold water, thereby cooling the molding groove. The material in 201 is cooled. When the material is cooled and formed, the hydraulic cylinder 401 drives the upper die head 402 to move up and separate from the lower die shell 2, and the first gear 502 and the second gear 503 are driven to rotate by the driving motor 501, and the support shaft 504 and the top plate 505 are driven to rotate by the second gear 503. The fan 506 is driven by the top plate 505 to rotate above the molding groove 201, and air is blown to the molding groove 201 by the fan 506. Air cooling and water cooling are carried out simultaneously, thereby accelerating the cooling speed of the material in the molding groove 201 and reducing the waiting time for cooling.
