Generally, the TV back panel is made of metal or plastic and has certain strength and durability. Its surface is usually designed with grooves and bends, which not only increase the structural strength, but also improve the appearance and make the entire TV more refined. In addition, there are multiple holes on the back panel for installing various parts and fixing screws, such as power interface, audio interface, video interface, etc. The design of these holes takes into account the convenience of installation and maintenance, so that users can easily connect various devices and accessories, thereby realizing more functions and applications.

[0003] Most of the existing TV back panels are made by stamping, and the four sides of the back panel are provided with a bending structure for connecting with the TV body. For example, Chinese patent announcement number CN211304486U discloses a "TV back panel bending forming mold", which can effectively bend the TV back panel by driving two push blocks to move respectively through two electric push rods, and the bending range can be adjusted by the user controlling the electric push rods, which is different from the disadvantage of the traditional bending forming mold that the bending angle cannot be changed; the drill rod is driven to rise by the electric push rod, and the TV back panel is punched by a plurality of drill rods, so that the punching can be realized during the forming process, which increases the production efficiency;

[0004] However, in actual production, the bent parts of the four sides of the produced back panels are prone to expansion / contraction during storage, resulting in uneven gaps with the screen during assembly, which makes it easy for dust to enter, affecting the use and service life of the TV after assembly, as well as affecting its appearance. Utility Model Content

[0005] The utility model aims to solve the shortcomings of the prior art that the bending part is prone to outward expansion / inward contraction and the gap with the screen is uneven during assembly, and proposes a mold for adjusting the shape of the TV back panel.

[0007] Design a mold for adjusting the shape of a TV back plate, comprising a lower mold base, an upper mold base and a back plate, wherein the back plate is arranged between the upper mold base and the lower mold base, and the edges of the back plate are all provided with a bending portion;

[0008] The upper die base and the lower die base are provided with adjustment components matched with the bending portion;

[0009] The adjusting assembly includes a supporting assembly disposed in the lower die seat, and a pressing assembly disposed in the upper die seat;

[0010] The supporting assembly is in contact with the top of the bending portion, and the pressing assembly is in contact with the bottom surface of the bending portion.

[0011] Furthermore, the support assembly and the pressing assembly both include an adjustment structure, the support assembly also includes a support block that cooperates with the adjustment structure, the pressing assembly also includes a pressing block that cooperates with the adjustment structure, and the lower mold base and the upper mold base are both provided with a slide groove that cooperates with the adjustment structure.

[0012] Furthermore, the support block is provided with a first contact surface matched with the bottom surface of the bending portion, and the lower end of the pressing block is provided with a second contact surface matched with the top of the bending portion.

[0013] Furthermore, the adjustment structure includes an adjustment member plugged into the lower die base or the upper die base, and the lower die base and the upper die base are both provided with a slot that matches the adjustment member and the slide groove.

[0014] Furthermore, the adjustment structure also includes a screw rod fixedly arranged on the adjustment member, a threaded sleeve is threadedly connected to the screw rod, and the threaded sleeve is fixedly connected to the support block or the lower pressure block.

[0015] Furthermore, a positioning piece is fixedly provided on the adjusting piece, and a limiting groove matching with the positioning piece is provided in the slot.

[0016] Furthermore, an adjusting portion is fixedly provided on the adjusting member, and a polygonal groove is formed on the adjusting portion.

[0017] The mold for adjusting the appearance of the TV back panel proposed by the utility model has the following beneficial effects:

[0018] In the utility model, the bottom surface and the top of the bent portion of the back plate are restricted by the support assembly and the pressing assembly, so as to correct the shape of the bent portion and repair the phenomenon of the bent portion expanding outwards / shrinking inwards;

[0019] Secondly, in the utility model, the positions of the support block and the pressing block are controlled by setting an adjustment structure, and the spacing between the support block and the pressing block is changed, so that back panels of different specifications can be corrected to make the gap with the screen uniform during assembly.
