A baffle 18 is provided. By using the baffle 18, it is convenient to block the speed of water flow, so that the water stays in the cooling groove 8, which is beneficial for the water to absorb the heat in the lower mold 2, improve the cooling efficiency of the lower mold 2, and thus facilitate the rapid molding of the product and improve the work efficiency of product production; a water tank 6 is provided on the bottom surface of the workbench 1, and a water supply component is provided in the water tank 6. By using the water supply component, it is convenient to inject water into the cooling groove 8, so as to facilitate the flow of water and thus facilitate the cooling of the lower mold 2; a rectangular cavity 13 is provided on the inner bottom surface of the annular sealing groove 9, and a trigger component is provided in the rectangular cavity 13. By using the trigger component, it is convenient to power on the water pump 16 after the upper mold 3 and the lower mold 2 are closed. The operation is simple and convenient, and the automation of the mechanism is improved.

In the present invention, the cooling trough 8 is composed of a plurality of U-shaped water troughs, and each U-shaped water trough is connected end to end, that is, the water outlet end of one U-shaped water trough is connected to the water inlet end of the next U-shaped water trough, so that water can flow in the lower mold 2 in a certain order, thereby facilitating the cooling of the lower mold, allowing the product to be quickly cooled and formed, thereby improving the work efficiency of product production.

In the utility model, the baffle 18 is an eight-shaped structure, and the end of the baffle 18 with a larger opening faces the water inlet end of the cooling trough 8; water enters from the large opening of the baffle 18 and flows out from the small opening, thereby flowing out from the small opening to hinder the water flow rate, thereby reducing the flow rate of water in the cooling trough 8 and allowing the water to take away the heat in the mold 2.

In the utility model, the water supply assembly includes a water pump 16 arranged in the water tank 6, the water outlet end of the water pump 16 is provided with a water pipe 5 connected with the water inlet end of the cooling tank 8, the water outlet end of the cooling tank 8 is provided with a return pipe 7 connected with the water tank 6, and a refrigerator 17 is installed in the water tank 6. Through the use of the refrigerator 17, it is convenient to cool the water in the water tank 6, thereby ensuring that the water entering the cooling tank 8 is cold water, which is convenient for absorbing the heat in the lower mold 2, thereby improving the work efficiency of product molding.

In the utility model, the trigger assembly includes a movable plate 10 slidably arranged in a rectangular cavity 13 and a pressure block 11 arranged on the top surface of the movable plate 10, and the top of the pressure block 11 movably penetrates into the annular sealing groove 9, a reset spring 15 is arranged between the movable plate 10 and the rectangular cavity 13, a copper sheet A12 is arranged on the bottom surface of the movable plate 10, and a copper sheet B14 is arranged on the inner wall of the rectangular cavity 13 to cooperate with the copper sheet A12.

Working principle: When the utility model is in use, the upper mold 3 and the lower mold are molded together through the price-raising mechanism, and then the liquid is injected into the lower mold 2 and the upper mold 3. After the upper mold 3 and the lower mold 2 are molded together, the pressing block 11 will be lowered into the rectangular cavity 13, and then the copper sheet A12 and the copper sheet B14 will be in contact. The water pump 16 works, and the cold water in the water tank 6 is injected into the cooling groove 8 through the water pipe 5 through the action of the water pump 16. Then, the water is blocked by the baffle 18 in the cooling groove 8, thereby preventing the flow speed of the water, which is convenient for better taking away the temperature in the lower mold 2, thereby improving the working efficiency of cooling the lower mold 2; then, finally, the water flows back to the water tank 6 from the water outlet end of the cooling groove 8 to realize the circulation of water, thereby facilitating the cooling of the lower mold 2, facilitating the rapid molding of the product in the lower mold 2, and improving the production efficiency of the product;

After the product is formed, the upper mold 3 is driven upward by the lifting mechanism to separate the upper mold 3 from the lower mold 2, and then the pressing block 11 is reset by the reset spring 15, so that the copper sheet A12 and the copper sheet B14 are separated, so that the water pump 16 is powered off and stops working.
