[0018] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0019] like Figures 1 to 2 As shown, in this embodiment, a computer monitor back panel forming mold includes an upper mold base 1, an upper splint 2, a lower template 3 and a lower mold base 4, the upper splint 2 is fixed to the lower end of the upper mold base 1, and a stop plate 5 is provided in the middle of the lower end of the upper splint 2, a bending block 6 is provided on one side of the stop plate 5, the bending block 6 is fixed to the upper splint 2 by screws, and a chamfer is provided on the side of the lower end of the bending block 6 close to the stop plate 5, the lower template 3 is located above the lower mold base 4, a number of press line blocks 7 are installed on the lower template 3, a ejector pin 8 is fixed on the lower template 3, and a first spring 9 is installed on the lower mold base 4, and the upper end of the first spring 9 is connected to the lower end of the ejector pin 8.

[0020] The upper die base 1 drives the upper splint 2 to move downward, the stop plate 5 presses the computer monitor back panel in the middle, and the bending block 6 bends the computer monitor back panel layer by layer on the side. The pressing line block 7 effectively changes the direction of material stress. During demolding, the ejector pin 8 lifts the computer monitor back panel under the action of the first spring 9.

[0021] An upper support plate 10 is provided above the upper die base 1, an upper pad 11 is connected between the upper support plate 10 and the upper die base 1, a beating plate 12 is provided between the upper die base 1 and the upper support plate 10, a second spring 13 is connected between the upper end of the beating plate 12 and the lower end of the upper support plate 10, a stop guide column 14 is fixed on the stop plate 5, the stop guide column 14 passes through the upper die base 1 and is connected to the beating plate 12, the lower end of the stop plate 5 is connected to the upper stripping plate 15, a lower stripping plate 16 is provided on the lower die base 4, and the lower template 3 is located in the middle of the lower stripping plate 16.

[0022] The punch press is pressed on the upper support plate 10. When the upper die base 1 controls the stop plate 5 to move downward, the upper stripping plate 15 squeezes the back panel of the computer monitor, forcing the stop plate 5 to rise. Under the action of the stop guide column 14, the punching plate 12 is raised upward, and the second spring 13 is compressed. When demolding, the second spring 13 extends, controlling the stop plate 5 to move downward, and the upper stripping plate 15 will separate from the back panel of the computer monitor.

[0023] A lower pad 17 is provided between the lower template 3 and the lower die base 4, a lower supporting plate 18 is provided below the lower die base 4, a number of lower pads 19 are connected between the lower supporting plate 18 and the lower die base 4, the lower die base 4 and the lower pads 19 are connected by screws, and the lower pads 19 and the lower supporting plate 18 are connected by screws.

[0024] By changing the bending forming structure of the mold, the upper stripping plate 15 will first press the back panel of the computer monitor when it descends on the punching machine table. The back panel of the computer monitor is bent downward around the bending block 6, and the pressing line block 7 is evenly fixed in the lower template 3. When the mold is closed, the pressing line block 7 changes the stress direction of the back panel of the computer monitor, achieving a flatness control within 0.3mm required.

[0025] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present invention and the technical principles used. Within the technical scope disclosed by the present invention, any changes or replacements that can be easily thought of by technicians familiar with this technical field should be included in the scope of protection of the present invention.
