[0017] 3. The present invention sets a demolding component. When the injection molding template rises after the injection molding operation is completed, the second sliding block is driven to move upward by the third spring. During the movement, the cold air inside the cooling box is injected into between the automobile interior decoration part and the lower mold through the third through hole opened in the second sliding block. The second protrusion on the back of the second sliding block contacts the first protrusion and vibrates. When the second sliding block moves upward, the automobile interior decoration part is separated from the lower mold, and the demolding operation is completed.

[0018] 4. The present invention provides a cleaning roller and a filter plate. When the second sliding block rises, the second sliding block pulls the rotating frame through the rotating rod, and the top surface of the filter plate is cleaned by the cleaning roller at the bottom of the rotating frame, thereby avoiding clogging of the filter plate and affecting the air flow inside the cooling box.
