Above the injection molding machine base 1, there is an injection molding box 2. Inside the right side of the injection molding box 2, an injection mold is installed. Inside the injection mold, a cooling pipeline is provided, and the cooling pipeline is used for the flow of cold water. On the right side of the front wall of the injection molding machine base 1, there is a first cooling box 4. Above the first cooling box 4, there is a first water pump 5. Between the first water pump 5 and the inlet of the cooling pipeline, there is a first drain pipe 6. On the right wall of the injection molding machine base 1, there is a second cooling box 8. In front of the second cooling box 8, there is a second water pump 14. Between the second water pump 14 and the first cooling box 4, there is a second drain pipe 15. Below the right wall of the injection molding box 2, there is a water storage tank 7. Between the water storage tank 7, the first cooling box 4 and the outlet of the cooling pipeline, there is a water delivery component. Between the water storage tank 7 and the second cooling box 8, there is a first water pipe, and at the middle position of the first water pipe, a first electromagnetic switch valve 13 is installed.

[0021] Among them, the inlet of the first water pump 5 is connected to a first water suction pipe 16. The first water suction pipe 16 is located inside the first cooling tank 4. The lower port of the first drain pipe 6 is communicated with the outlet of the first water pump 5. The inlet of the second water pump 14 is connected to a second water suction pipe 17. The second water suction pipe 17 is located inside the second cooling tank 8. The lower end of the second drain pipe 15 is communicated with the outlet of the second water pump 14. The upper end of the second drain pipe 15 is communicated with the inside of the first cooling tank 4. The water delivery assembly includes a tee pipe 9 and two second water delivery pipes 12.

[0022] Working principle: When cooling the injection mold, first start the first water pump 5.

Open the second electromagnetic switch valve 11, and the water flow returns to the inside of the first cooling tank 4 through the front second water delivery pipe 12 for cooling. After a long time of circulation, the water in the first cooling tank 4 cannot be quickly cooled. At this time, close the second electromagnetic switch valve 11 and open the first electromagnetic switch valve 10. The circulated water flow enters the inside of the water storage tank 7. Start the second water pump 14. The second water pump 14 pumps out the cold water in the second cooling tank 8 and transmits it to the inside of the first cold water tank 4 through the second drain pipe 15 to ensure that the water flow entering the cooling pipeline is always cold water. After a period of time, reopen the second electromagnetic switch valve 11 and the third electromagnetic switch valve 13 and close the first electromagnetic switch valve 10. The water in the water storage tank 7 enters the inside of the second cooling tank 13 for cooling. Continuously circulating the above operations can ensure the cooling of the injection mold for a long time.
