In use, the high-temperature water in the upper mold 3 is discharged into the third water pipe 17 through the hose, and then discharged into the high-temperature water tank 5 through the third water pipe 17, and the hose does not affect the lifting action of the upper mold 3.

[0034] By installing a hose between the drain valve 15 and the third water pipe 17, it is convenient to uniformly discharge high-temperature water into the high-temperature water tank 5.

[0035] Working principle: In use, the upper mold 3 is lowered and combined with the lower mold 2, and then injection molding is performed. After the injection molding is completed, low-temperature cooling water is injected into the lower mold 2 and the upper mold 3, wherein the low-temperature cooling water of the upper mold 3 is drawn in through the booster pump 6. The low-temperature cooling water exchanges heat with the upper mold 3 to form high-temperature water, which is discharged into the high-temperature water tank 5 through the drain valve 15. The high-temperature water can be used as production or living water. In this way, the upper mold 3 can be cooled and cooled, and the cooling speed of the mold can be greatly improved, and the cooling forming can be accelerated.
