[0002] A television is mainly composed of a casing, panel controller, movement, cathode ray tube, remote control phone, etc. The movement is composed of four parts: power supply, signal processing, scanning circuit, and bus control. The mold is a tool that uses external force to make the blank into a part with a specific shape and size. Therefore, in the production process of the television casing and back panel, stamping molds are usually used for production.

[0003] After searching, the utility model patent with publication number CN212121429U discloses a bending and forming mold for the back panel of a television, including a base plate, a lower template is provided at the upper end of the base plate, a lower mold base is provided at the upper end of the lower template, an empty groove is provided inside the lower mold base, a mold cavity is provided inside the empty groove, a clamping block is provided at the bottom end of the mold cavity, a clamping groove is provided outside the clamping block and inside the lower mold base, a docking block is provided at the bottom end of the empty groove, and a docking groove is provided outside the docking block and inside the mold cavity. The utility model can take out the mold cavity with the finished product and replace the empty mold cavity to continue the operation by adding a card block, a card slot, a docking block and a docking slot, and it is also convenient to replace the damaged mold cavity. The operation is simple and convenient, and the work efficiency is improved. By adding a fixing block, a slot and an insert block, a gap can be left between the upper template and the lower mold base, avoiding the problem of the upper template and the lower mold base being too tightly clamped, causing the back panel of the TV to be pressed black.

The positioning assembly 200 is used for adjusting the positioning, and a driving assembly 300 is provided at the bottom of the lower mold base 103 for driving the positioning assembly 200 to move so as to adjust and fix the position of the TV back panel. When in use, the TV back panel to be processed is placed on the lower mold 105, and then the driving assembly 300 is started to drive the positioning assembly 200 to move, and the TV back panel to be processed is positioned so that it is in the center position of the lower mold 105. Then, the upper mold 106 is driven downward along the support rod 101 by the first driving cylinder 107. The auxiliary positioning component 400 first abuts against the back panel to be processed to assist in fixing it, thereby avoiding the offset during the folding process that affects the folding effect, and then the folding operation is completed under the stamping of the upper mold 106.

[0027] Reference Figure 2-5The positioning assembly 200 includes a connecting frame 201 slidably connected to the lower mold base 103, a mounting plate 202 arranged on the top of the connecting frame 201, an elastic connecting member 203 arranged on the mounting plate 202, and a push plate 204 arranged at the end of the elastic connecting member 203. When in use, the connecting frame 201 is driven to move by the driving assembly 300, and then the mounting plate 202, the elastic connecting member 203 and the push plate 204 are driven to move and drive the back panel to be processed to move so that it is in the centering position of the lower mold 105, completing the adjustment and positioning operation of the back panel, and then the positioning assembly 200 is driven away from the back panel by the driving assembly 300 to avoid it affecting the folding operation. The positioning assembly can automatically and accurately center and adjust the back panel of the TV to be processed, and then perform the stamping operation in conjunction with the upper mold, which can well improve the accuracy of the folding of the TV back panel, thereby ensuring the folding quality of the TV back panel.

[0028] Reference Figure 4-5 The elastic connecting member 203 includes a sliding rod 205 that is arranged on the mounting plate 202 and one end of which is fixedly connected to the push plate 204, and a spring 206 that is sleeved on the outside of the sliding rod 205 and arranged between the push plate 204 and the mounting plate 202. Through the arrangement of the sliding rod 205 and the spring 206, it is possible to adjust the position of the back plate to be processed and avoid damage to it.

[0029] Reference Figure 2 、 Figure 4 A cross slot 1031 is provided on the lower die base 103 to cooperate with the connecting frame 201. The connecting frame 201 passes through the cross slot 1031 and extends downward. The setting of the cross slot 1031 improves the feasibility of the device.

[0030] Reference Figure 1-3 Two groups of positioning components 200 are symmetrically arranged along the lower mold base 103 in the horizontal and vertical directions. Through the horizontal and vertical settings, the horizontal and vertical adjustment positioning of the TV back panel is realized, so that it can handle the folding position more accurately.

[0031] Reference Figure 4 In order to further prevent the back panel of the TV from being damaged during adjustment, a rubber pad 207 is provided on the inner wall of the push plate 204 .

[0032] Reference Figure 5-6The driving assembly 300 includes a rotating disk 301 rotatably arranged at the bottom of the lower mold base 103, a connecting block 302 connected to the bottom of the connecting frame 201, a connecting plate 303 rotatably connected between the connecting block 302 and the rotating disk 301, and a second driving cylinder 305 connected between the two symmetrically arranged connecting blocks 302 through a connecting seat 304. When in use, the second driving cylinder 305 is started to drive the connecting block 302 and the connecting frame 201 connected thereto to move along the cross slide 1031. The rotating disk 301 and the connecting plate 303 are arranged in conjunction with each other, and the mutually symmetrical positioning assemblies 200 will move synchronously, thereby moving the back panel of the TV to be processed to the middle position of the lower mold 105, making it more accurate when folding the edge, thereby improving the quality of the back panel folding.

[0033] Reference Figure 2 and Figure 5 The auxiliary positioning component 400 includes an elastic retractable rod 401 arranged inside the upper mold 106 and a pressure plate 402 connected to the end of the elastic retractable rod 401. Through the provided pressure plate 402 and the elastic retractable rod 401, when the upper mold 106 moves downward to fold the back plate, the pressure plate 402 first resists the back plate, and then when the upper mold 106 continues to descend, the elastic retractable rod 401 is provided so that the pressure plate 402 can still resist the back plate without causing damage to it, thereby achieving the effect of auxiliary positioning of the back plate and avoiding its displacement during the folding process and affecting the folding quality.

[0034] Specifically, when the folding device for processing the back panel of a television is used: the back panel of the television to be processed is placed on the lower mold 105, and the second driving cylinder 305 is started to drive the connecting block 302 and the connecting frame 201 connected thereto to move along the cross slide 1031, and the rotating disk 301 and the connecting plate 303 are provided, and the mutually symmetrical positioning components 200 will move synchronously, thereby moving the back panel of the television to be processed to the middle position of the lower mold 105, avoiding the dimensional deviation of the folding position of the back panel and affecting the accuracy of this side, when the connecting frame 201 moves along the cross slide 1031 , it will drive the installation plate 202, the elastic connector 203 and the push plate 204 to move and drive the back panel to be processed to move so that it is in the center position of the lower mold 105, completing the adjustment and positioning operation of the back panel, and then drive the positioning component 200 away from the back panel through the driving component 300 to avoid it affecting the folding operation. The positioning component can automatically and accurately center and place the back panel of the TV to be processed, and then perform the stamping operation in conjunction with the set upper mold, which can greatly improve the accuracy of the folding of the TV back panel, thereby ensuring the folding quality of the TV back panel.
