Description

Technical Field

[0001] This utility model relates to the field of cooling structure technology, specifically a cooling structure for injection molds. Background Technology

[0002] Injection molds are tools used in plastic injection molding processes. They consist of a moving mold and a fixed mold, forming a closed cavity. Molten plastic is injected into the cavity under high pressure, cooled, and solidified. The mold then separates, ejecting the plastic product. They can produce plastic products with complex shapes and precise dimensions. However, most existing injection mold cooling methods are limited to traditional heat dissipation methods, such as simple air cooling or natural cooling. These methods are insufficient to meet the heat dissipation requirements of the equipment under high load operation, resulting in poor cooling performance. This not only affects the working efficiency and stability of the equipment but may also accelerate the aging of internal components. Utility Model Content

[0028] It is understood that in this utility model, mold 1 and mold 2 are closed to complete the injection molding of the workpiece. Cooling water is connected to an external cooling water inlet pipe 6. The cooling water enters one of the connecting water tanks 5 through the cooling water inlet pipe 6. The cooling water in the connecting water tank 5 enters the cooling water pipe 3 through the first connecting water pipe 16, and then enters the S-shaped cooling pipe 4 through the second connecting water pipe 17. The cooling water pipe 3 and the S-shaped cooling pipe 4 cool the mold 2. The fan connected to the air inlet duct 9 has an air inlet pipe at its input end and a dust filter at one end to filter dust. The air is blown into the air inlet duct 9 through the output end of the fan. The airflow enters the side ventilation box 8 and then enters the side distribution box 10. The airflow is then blown through the air blowing frame 11 on one side of the distribution box 10 and blown out through the air blowing frame 11 to cool down the first heat dissipation fin 13 and the second heat dissipation fin 14, quickly dissipating the heat.

[0029] Please see Figures 1 to 6 Both ends of the cooling water pipe 3 are fixedly connected to a No. 1 connecting water pipe 16, which is fixedly connected to the No. 2 mold 2.
