[0022] As Figures 1-3 shown, the die structure with synchronous shaping function, the die is provided with an upper die and a lower die, the upper die is provided with a punch 80, the lower die is provided with a lower die seat 10 and a lower die plate 20, the lower die plate 20 is provided with a forming pin 30 matched with the punch 80; wherein:

[0023] On the lower mold, one or more shaping parts 40 are provided on the outside of the forming insert 30. The upper end or the side end facing the forming insert of each shaping part 40 is adapted to the product. Each shaping part 40 is connected to an adjustment component 50. Each adjustment component 50 can drive a shaping part 40 to slide horizontally on the lower mold to approach or move away from the forming insert 30.

[0024] The lower mold also has a lower stripper plate 90 at the upper end of the lower template 20;

[0025] An upper template 100 and an upper ejector plate 110 are provided on the side of the upper punch 80. The upper ejector plate 110 is matched and provided above the lower ejector plate 90 and on the side of the upper template 100.

[0026] Furthermore, each shaping component 40 includes a mounting plate 41 and one or more shaping blocks 42. Each shaping block 42 is disposed on the upper end or side wall of the mounting plate 41. Each mounting plate 41 is slidably mounted on a first slide rail 60 and is connected to an adjustment component 50 in a transmission manner. Each first slide rail 60 is horizontally arranged and detachably fixed to the lower mold base 10.

[0027] Understandably, the split-structure shaping component 40 is not only easy to manufacture and assemble, but also facilitates appropriate fine-tuning of the size of the block 42 and its relative position with the mounting plate, making production operations more flexible and convenient.

[0028] In one embodiment of this utility model, each of the several adjustment components 50 includes a vertically arranged elastic component 51, a limiting component 52, and a transmission component 53.

One end of the elastic reset component 70 is tractively connected to the mounting plate 41. The ends of each transmission component 53 facing a shaping component 40 are inclined or arc-shaped. The elastic component 51 is a nitrogen spring.

[0029] like Figure 2 , 3 As shown, during mold closing, the upper mold plate 100 and the upper ejector plate 110 first press the sheet material together. Due to the sliding connection of the limiting component 52 and the rebound buffering effect of the elastic component 51, the upper mold continuously pushes the lower ejector plate 90 and the lower mold plate 20 downward. Simultaneously, the transmission component 53 fixed on the lower mold base 10 moves upward relative to the lower mold plate 20. The inclined or arc surface of its side wall slides relative to the mounting plate 41 and pushes it to slide on the first slide rail 60, so that the shaping block 42 approaches the forming insert 30 and cooperates with it to shape the bent sheet material.

[0030] In another embodiment of the utility model, several adjusting assemblies 50 all include push plate 54 and locking piece 55, second slide rail 120 is fixedly connected with lower die seat 10, push plate 54 is slidably arranged on second slide rail 120 and is detachably fixedly connected with shaping piece 40, second slide rail 120 is fixedly connected with lower die seat 10, locking piece 55 passes through push plate 54 or second slide rail 120 and is detachably fixedly connected with second slide rail 120 or push plate 54, and each shaping block 42 is arranged at the upper end of shaping piece 40.

[0031] As shown in the figure, when assembling the die or in the open die state, the position of shaping block 42 is set according to the actual structure of the bent plate, when adjusting the position, locking piece 55 is removed and push plate 54 is pushed to slide on second slide rail 120 to the appropriate position, adjusting block 42 can be moved to the appropriate position, and finally locking piece 55 is locked. Figure 1 When the die is closed, push plate 54 and locking piece 55 always remain in a fixed state, and shaping block 42 cooperates with forming son 30 and other shaping blocks 42 to shape the plate.

[0032] The utility model discloses a plurality of shaping pieces 40 that can be moved relative to the lower die or fixed on the lower die are arranged on the lower die, the structure of each part on the bent plate can be positioned and shaped while the upper die bends the plate, the influence of bending operation on each structure on the plate is avoided, subsequent shaping is not needed, the behavior precision of the product can be ensured, the bending quality is improved, and the production process can be reduced, and the production efficiency is improved.

[0033] The above is not any limitation on the technical range of the utility model, and any modification, equivalent change and modification of the above embodiment according to the technical essence of the utility model still belong to the range of the technical scheme of the utility model.
