[0030] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0031] Example

[0032] like Figure 1-4 As shown, this embodiment discloses an F-side side folding forming device, including an upper die, a lower die, a side folding assembly and a punching assembly;

[0033] The upper die includes an upper clamping plate 11, an upper stripping plate 12 provided on one side of the lower end surface of the upper clamping plate 11, and a first pressing block 13 and a first inserting knife 14 both provided on the other side of the lower end surface of the upper clamping plate 11;

[0034] The lower die includes a lower clamping plate 21;

[0035] The side folding assembly is arranged above the lower mold, and includes a lower stripping plate 31, a second inserting knife 32, a first sliding seat 33 and a forming block 34. The lower stripping plate 31 is arranged corresponding to the upper stripping plate 12. The second inserting knife 32 is arranged on the upper end surface of the lower clamping plate 21 and can move up and down relative to the lower stripping plate 31. The first sliding seat 33 is arranged on one side of the second inserting knife 32 and can move left and right relative to the lower stripping plate 31. The forming block 34 is arranged on the first sliding seat 33.

[0036] The stamping assembly is arranged on one side of the side folding assembly, and the stamping assembly includes a second sliding seat 41, a punch 42, a second pressure block 43 and a first sleeve screw 44. The second sliding seat 41 is arranged on the upper end surface of the lower clamping plate 21 and can move left and right relative to the lower clamping plate 21. The punch 42 and the second pressure block 43 are arranged on the second sliding seat 41 from bottom to top. The first sleeve screw 44 is embedded in one side of the second pressure block 43, so that the second pressure block 43 can move left and right relative to the second sliding seat 41. The first sleeve screw 44 is fixedly connected to the second pressure block 43 and can move left and right relative to the second sliding seat 41.

[0037] The forming device in this embodiment cooperates with the forming block 34, the punch 42 and the second pressing block 43 to quickly and accurately act on the side of the back plate 5 to achieve F-side folding forming.

[0038] Furthermore, the punching assembly is arranged below the first pressing block 13 and the first inserting blade 14 , and the first inserting blade 14 and the second sliding seat 41 are correspondingly arranged.

[0039] Furthermore, the first plunger 14 has a first inclined surface 15 at its bottom, and the second sliding seat 41 has a second inclined surface 45 at its top that cooperates with the first inclined surface 15. During the mold closing process, as the first plunger 14 moves downward with the upper mold, the first inclined surface 15 comes into contact with the second inclined surface 45. Through the cooperation of the first inclined surface 15 and the second inclined surface 45, the first plunger 14 pushes the second sliding seat 41 to move along the upper end surface of the lower clamping plate 21, causing the second sliding seat 41 to move closer to the back plate 5.

[0040] Furthermore, a third inclined surface 35 is provided on the top of the second plunger 32, and a fourth inclined surface 36 is provided on the bottom of the first sliding seat 33 to mate with the third inclined surface 35. During the mold closing process, the upper mold moves downward, squeezing the second plunger 32 and causing it to move upward relative to the lower stripper plate 31. Through the interaction of the third inclined surface 35 and the fourth inclined surface 36, the second plunger 32 pushes the first sliding seat 33 along the lower end surface of the lower stripper plate 31, causing the first sliding seat 33 to move closer to the back plate 5.

[0041] Furthermore, the upper stripping plate 12 and the lower stripping plate 31 are correspondingly arranged. When the mold is closed, a mold cavity for placing the back plate 5 is formed between the upper stripping plate 12 and the lower stripping plate 31. The operator directly places the back plate 5 in the mold cavity, and the back plate 5 is molded between the upper mold and the lower mold.

[0042] Furthermore, the stamping assembly further includes a third pressing block 46, which is disposed on the upper end surfaces of the second pressing block 43 and the second sliding seat 41 and is fixedly connected to the second sliding seat 41. When the mold is closed, the first pressing block 13 presses the third pressing block 46, and the third pressing block 46 presses the second pressing block 43. This arrangement prevents the second pressing block 43 from warping upward, thereby ensuring the quality of the back plate 5 molding.

[0043] Furthermore, the stamping assembly also includes a fixed seat 47 and a second sleeve screw 48. The fixed seat 47 is fixedly arranged on the upper end surface of the lower clamping plate 21 and is located on one side of the second sliding seat 41. The second sleeve screw 48 passes through the fixed seat 47 and is connected to the second sliding seat 41. The second sleeve screw 48 is fixedly connected to the second sliding seat 41 and can move left and right relative to the fixed seat 47. After the back plate 5 is side-folded and formed, the upper die moves upward, the first inclined surface 15 and the second inclined surface 45 cooperate, and the second sleeve screw 48 drives the second sliding seat 41 to move away from the back plate 5, so that the second sliding seat 41 drives the punch 42, the second pressing block 43 and the third pressing block 46 to return to their original positions.

[0044] Furthermore, the lower die also includes a lower die base 22, a lower support plate 23, and a nitrogen spring 24. The lower die base 22 is located on the lower end surface of the lower clamping plate 21, and the lower support plate 23 is located on the lower end surface of the lower die base 22. The bottom of the nitrogen spring 24 is fixed to the upper end surface of the lower support plate 23. The top of the nitrogen spring 24 passes through the lower die base 22 and the lower clamping plate 21 from bottom to top and is connected to the side folding assembly. After the back panel 5 is side-folded and formed, the upper die moves upward, the third inclined surface 35 and the fourth inclined surface cooperate, and the side folding assembly is the movable part. The nitrogen spring 24 pushes the side folding assembly upward, so that the first sliding seat 33 drives the forming block 34 to return to its original position.

[0045] Furthermore, the upper die further includes an upper die base 16 , and the upper die base 16 is disposed on the upper end surface of the upper clamping plate 11 .

[0046] The mold closing process in this embodiment is as follows:

[0047] (1) The operator first places the back plate 5 to be formed in the mold cavity; (2) The upper mold moves downward under the action of the punch, and the upper stripper 12 first contacts the upper end surface of the back plate 5; (3) The upper mold continues to move downward, causing the side folding assembly to move downward, and the second insert 32 provided on the upper end surface of the lower clamping plate 2 is squeezed and moves downward, and the third inclined surface 35 and the fourth inclined surface 36 are relatively displaced, so that the second insert 32 pushes the first sliding seat 33 to move toward the direction of the end of the back plate 5 to be side folded and formed (such as Figure 2 As shown in the figure, the nitrogen spring 24 located below the side folding assembly is compressed downward; while the upper mold moves downward, the first plunger 14 moves downward with the upper mold, and the first inclined surface 15 and the second inclined surface 45 come into contact. Under the cooperation of the first inclined surface 15 and the second inclined surface 45, the first plunger 14 pushes the second sliding seat 41 to move toward the direction close to the end of the back plate 5 to be side folded and formed (as shown in the figure). Figure 2 As shown in the figure, the first sliding seat 33 and the second sliding seat 41 move toward each other; the punch 42, the second pressing block 43 and the third pressing block 43 provided on the second sliding seat 41 move along with the second sliding seat 41 toward the direction of the end of the back plate 5 to be folded and formed. The second pressing block 43 first contacts the side of the back plate 5 and moves relative to the second sliding seat 41 in the opposite direction away from the side of the back plate 5 under the pushing action of the side of the back plate 5 (as shown in the figure, the first sliding seat 33 and the second sliding seat 41 move toward the direction away from the side of the back plate 5). Figure 2 The punch 42 moves along with the second sliding seat 41 toward the end of the back panel 5 to be folded and formed, and acts on the side of the back panel 5; when the forming block 34, the punch 42 and the second pressing block 43 all act on the side of the back panel 5, the three cooperate with each other to complete the F-side folding forming of the back panel 5.

[0048] The mold opening process in this embodiment is as follows:

[0049] (1) After the back plate 5 completes the F-side folding, the upper die moves upward under the action of the punch press; (2) The side folding assembly moves upward under the action of the nitrogen spring 24, and the second plunger 32 moves downward relative to the lower stripper plate 31, and with the cooperation of the third inclined surface 35 and the fourth inclined surface 36, the first sliding seat 33 and the second plunger 32 return to their original positions; (3) As the upper die moves upward, the first plunger 14 moves upward with the upper die, and with the cooperation of the first inclined surface 15 and the second inclined surface 45, the second sleeve screw 48 drives the second sliding seat 41 to move away from the back plate 5, so that the second sliding seat 41 drives the punch 42, the second pressure block 43 and the third pressure block 46 to return to their original positions.
