Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die for a back plate of a curved display module. Background Art

[0002] The curved LED display screen is a display device with a curvature, which enhances the user's visual experience of spaciousness. The curved display screen gives people a wider field of view, because the edge that is slightly curved towards the user can be closer to the user, and the viewing angle is basically the same as the center of the screen. The back panel of the curved LED display screen is an important part of the display screen. During the production process of the display screen back panel, the corresponding stamping operation is required to complete the production of the entire back panel, and the stamping requires the assistance of the corresponding stamping die;

[0003] After checking the public (announcement) number: CN218314810U, a curved LED display back panel stamping die is disclosed. This technology discloses "a curved LED display back panel stamping die, including a lower die and an upper die, both side surfaces of the lower die and the upper die are fixedly connected with ear plates, and the two side surfaces of the two ear plates are installed with hydraulic rods. A stamping groove is opened inside the lower die, and a top plate is slidably connected inside the stamping groove. Both side surfaces of the top plate are fixedly connected with connecting rods, and one end of the two connecting rods is slidably connected to the inside of the lower die. An ejection assembly is provided inside the lower die, and a blanking cavity is provided inside the lower die". It has "the elastic force of the No. 2 compression spring pushes the moving sleeve and the connecting rod sliding groove, and the connecting rod drives the top plate to eject the stamped curved display back panel out of the lower die, which can avoid the phenomenon that the curved display back panel is not easy to demold in the lower die, and the collection frame can be used to collect the waste after punching".

[0004] In the above scheme, after the stamping is completed, the elastic force of the spring will push the top plate to eject the curved display back plate from the lower mold; however, when the stamping plate applies downward pressure during the stamping process, it will compress the spring at the same time. This process may cause the spring to produce uneven force when the curved display back plate is pressed down; this uneven force will cause the curved display back plate to be difficult to maintain a horizontal posture when it reaches the lowest stamping position, thereby adversely affecting the entire stamping process.
