[0027] When in use, the device is installed on an injection molding machine. The water inlet pipe 8 is connected to a water source through a hose, and the feed pipe 11 is connected to a feeding structure. Then, the raw material is injected between the fixed mold 1 and the moving mold 4 through the feed pipe 11 for injection molding. After the injection molding is completed, water can enter the inside of the cooling concave plate 14 through the water inlet pipe 8. The first guide plate 17 and the second guide plate 18 are used to guide the coolant so that the coolant can enter and cool the injection molded part through the injection molding top plate 13. And the water can be discharged through the water outlet pipe 19, enabling the water to flow inside the cooling concave plate 14, thereby reducing the temperature inside the cooling concave plate 14. Then, the moving mold 4 is opened, and the hydraulic rod 9 is started. The hydraulic rod 9 pushes the cooling concave plate 14, and the cooling concave plate 14 pushes the injection molding top plate 13, thereby pushing the rubber pad out of the fixed mold 1 after the injection molding is completed, and quickly demolding the injection molded part.
