The upper cooling box 5 and the lower cooling box 7 can be interconnected through the communication hole 17, so that The cold air introduced into the lower cooling box 7 by the cold air inlet pipe 8 can enter the upper cooling box 5, and the hot air in the lower cooling box 7 can be extracted by the exhaust pipe 2 through the upper cooling box 5, thereby accelerating the cooling efficiency. The upper cooling box 5, the upper mounting seat 11 and the upper injection mold 12 form a card slot 4 of an annular structure, and the upper cooling box 5 and the lower cooling box 7 have the same size. The arrangement of the upper cooling box 5 and the lower cooling box 7 of this structure enables the mold and the cooling structure to be installed separately. According to the specific shape of the mold, the corresponding upper cooling box 5 and the lower cooling box 7 are manufactured, so that the cooling structure is close to the injection cavity of the injection mold to achieve the best cooling effect, and the upper cooling box 5 is respectively connected to the upper mounting seat 11 and the upper injection mold 12 on the upper and lower sides, and the lower cooling box 7 is respectively connected to the lower injection mold 1 on the upper and lower sides. 3 and a lower mounting seat 14, the upper cooling box 5 and the lower cooling box 7 are provided with a cavity structure at the parts close to the injection upper mold 12 and the injection lower mold 13, and the cooling coil 9, the heating module 10, the connecting pipe 3 and the cooling ring pipe 6 are installed in the cavities of the upper cooling box 5 and the lower cooling box 7, the cooling ring pipe 6 and the connecting pipe 3 are interconnected through pipe fittings, and the cooling ring pipe 6 is located in the annular cavity on the side of the upper cooling box 5 and the lower cooling box 7. This structure enables the upper cooling box 5 and the lower cooling box 7 to cool the side of the injection upper mold 12 and the injection lower mold 13 respectively through the cooling ring pipe 6, and a circle of exhaust pipe 2 and cold air inlet pipe 8 are respectively provided on the side of the upper mounting seat 11 and the lower mounting seat 14, and the exhaust pipe 2 and the cold air inlet pipe 8 are connected to the upper mounting seat 11 and the lower mounting seat A sealing connection seat 18 is provided between the mounting seats 14, and the sealing connection seat 18 is connected to the upper cooling box 5 and the lower cooling box 7 by pipelines respectively. The upper end of the annular structure on the side of the lower cooling box 7 is higher than the upper end height of the injection lower mold 13 and the lower mounting seat 14, and the lower cooling box 7 is connected with the card slot 4. After the injection upper mold 12 and the injection lower mold 13 are combined to form an injection cavity, the lower cooling box 7 is inserted into the card slot 4 to achieve the connection between the lower cooling box 7 and the upper cooling box 5, so that cold air can enter and hot air can be discharged, so as to achieve rapid cooling, improve the injection molding quality of polymer materials, and thus improve the production efficiency of polymer materials. Cooling water inlet and outlet 15 are provided at both ends of the cooling coil 9, and the upper end of the cooling coil 9 is connected with the connecting pipe 3 through a pipe fitting.This structure allows the upper cooling box 5 and the lower cooling box 7 to perform large-area cooling treatment through the cooling coil 9, and allows the cooling water to flow between the cooling coil 9, the connecting pipe 3 and the cooling ring pipe 6.

[0022] Working principle: When using the polymer material injection molding cooling device, first, when the polymer material is being injection molded, the injection molding device forms an injection molding cavity through the injection molding upper mold 12 and the injection molding lower mold 13, and the lower cooling box 7 is connected through the card slot 4, so that the upper cooling box 5 is connected with the lower cooling box 7, and the upper mounting seat 11 and the lower mounting seat 14 are used for the installation and fixing of the upper cooling box 5 and the lower cooling box 7 respectively. The support member 16 is used for the structural reinforcement of the upper cooling box 5 and the lower cooling box 7. After the molten polymer material is pressed into the injection molding cavity of the mold from the syringe, the injection molding cooling device body 1 is cooled, and the cooling water enters the cooling water inlet and outlet 15. The cooling coil 9 enters the cooling ring pipe 6 through the connecting pipe 3 to cool the polymer material. At the same time, the fan passes the cold air into the cold air inlet pipe 8, and is introduced into the lower cooling box 7 through the sealing connecting seat 18, and then enters the upper cooling box 5 through the connecting hole 17. At the same time, the exhaust pipe 2 is used in conjunction with the exhaust fan to extract the gas in the upper cooling box 5 and the lower cooling box 7. Since the hot air has a lower density than the cold air, the hot air flow rises to achieve rapid heat discharge, thereby accelerating the cooling efficiency of the injection molding cooling device body 1. The heating module 10 is used to maintain the temperature of the mold surface to prevent uneven cooling of the polymer material during the injection molding process, thereby completing a series of tasks.
