[0024] The specific use process is as follows. When the extrusion molding device 1 extrudes the PVC profile body 2 and it passes through the inside of the cooling box 7, after the spray cooling mechanism 3 extracts the coolant inside the water tank 4, finally the coolant is sprayed on the surface of the PVC profile body 2 through the spray cooling mechanism 3, thereby cooling it.

The spray cooling mechanism 3 can also stir the coolant, thereby improving the cooling speed of the coolant. After the PVC profile body 2 passes through the cooling box 7, the cold air is discharged through the wind hood 6 by an external air supply mechanism to perform secondary cooling and temperature reduction on the PVC profile body 2.
