TECHNICAL FIELD

[0001] The application relates to the technical field of automobile die, in particular to a forming die facilitating demolding of a front roof cover. BACKGROUND

[0002] The automobile front roof cover forming die is a key tool in automobile manufacturing and is used for stamping a metal plate to form a roof structure. The die is composed of an upper die and a lower die. The upper die is responsible for applying pressure, and the lower die provides a forming shape. During stamping, the metal plate is placed between the upper and lower dies, and the upper die is lowered to form the plate into a set shape.

[0003] In the related art, since the sunroof cutter and the air cylinder are both in the die, it is difficult to determine whether the sunroof cutter in the die has been switched in place, which may cause the production of the automobile roof cover to be scrapped or even cause a safety accident. In order to reduce the occurrence of safety accidents, for example, the prior art with the publication number CN216226481U provides a stamping die for an automobile roof cover. The device can visually display the switching state of the sunroof cutter on the basis of automatically switching the sunroof cutter, thereby avoiding misoperation by the operator and causing a safety accident.

[0004] Although the prior art in the above can visually display the switching state of the sunroof cutter on the basis of automatically switching the sunroof cutter, it avoids misoperation by the operator, but the top of the automobile front roof cover is usually not flat and smooth. The protruding part of the front roof cover is easy to be stuck on the upper die during demolding, which needs to be manually removed, which is not convenient for subsequent transfer processing and increases the workload and difficulty of the workers.

[0005] In view of this, we propose a forming die facilitating demolding of a front roof cover. CONTENT OF THE INVENTION
