Correspondingly, an automobile inner roof is usually provided with a sunroof hole for light transmission in the middle during production. The automobile roof is formed by hot pressing of raw materials such as foaming materials, knitted fabrics and non-woven fabrics through a die. The sunroof hole for light transmission is obtained by cutting the middle part of the roof after hot pressing. The area of the raw material of the automobile roof is generally larger than the actual area of the automobile roof.

When pressing, the sinking pressing block 12 presses the middle part of the raw material into the recessed groove 22. After forming, the middle part of the roof is cut to form a sunroof hole for accommodating or installing a sunroof. The pressing member 3 on the side of the sinking pressing block 12 can further press the side of the raw material near the sunroof part, so that the edge of the position to be cut to form the sunroof hole is protruded towards the bottom die 21, thereby making the edge of the sunroof hole closer to the sunroof when the roof is installed on the vehicle, reducing the gap between the roof and the sunroof, and reducing the cost of re-opening the mold.
