Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] Please see Figure 1 , Figure 2 and Figure 3 In one embodiment of this application, a bright trim strip folding mold 10 is provided, which includes a folding mechanism for folding the bright trim strip 600. The bright trim strip folding mold 10 further includes an upper mold 100, a lower mold 200, a pressing mechanism 300, and a torsion mechanism. The upper mold 100 can move in a direction closer to or farther from the lower mold 200. Specifically, the bright trim strip folding mold 10 also includes a mold driving member, which is used to drive the upper mold 100 to move in a direction closer to or farther from the lower mold 200.

[0027] The pressing mechanism 300 includes a support base 310 disposed on the lower mold 200 and a pressing member 320 disposed on the upper mold 100. The support base 310 and the pressing member 320 are disposed opposite to each other. The support base 310 is used to support the bright trim strip 600 to be shaped. The pressing member 320 can press the bright trim strip 600 to be shaped tightly against the support base 310.

[0028] The torsion mechanism includes a clamping assembly 400 and a torsion assembly 500 disposed on the lower mold 200. The clamping assembly 400 is used to clamp the bright trim strip 600 to be shaped. The torsion assembly 500 is connected to the clamping assembly 400 and is used to drive the clamping assembly 400 to rotate at any angle to torsion shape the bright trim strip 600. For example, the torsion assembly 500 is used to drive the clamping assembly 400 to rotate at any angle with the extension direction of the bright trim strip 600 as the center of rotation.

[0029] The folding mechanism folds one end of the bright trim strip 600, the pressing mechanism 300 presses the bright trim strip 600 to be shaped, and the twisting mechanism twists and shapes the part of the bright trim strip 600 to be shaped. It should be noted that the part of the bright trim strip 600 to be shaped is the other end of the bright trim strip 600.

[0030] By setting up the pressing mechanism 300, the support base 310 and the pressing component 320 can press the bright trim strip 600 to be shaped, preventing the bright trim strip 600 from shifting during the subsequent torsion shaping process and affecting the shaping effect. By setting up the torsion mechanism, the clamping component 400 can clamp the bright trim strip 600 to be shaped, and the torsion component 500 can drive the clamping component 400 to rotate at any angle, so that the bright trim strip 600 can be torsion shaped at any angle. This application integrates the pressing mechanism 300 and the torsion mechanism on the mold with the folding mechanism, so that the mold not only has the function of folding, but also can realize the torsion shaping of the bright trim strip 600. There is no need to perform mold surface reduction compensation processing, which can better cope with material fluctuations. The structure is simple, and there is no need to develop a separate special shaping fixture, avoiding the need to spend a lot of time and development costs.

[0031] Please see Figure 1 , Figure 2 and Figure 3 According to some embodiments of this application, optionally, the support base 310 is height-adjustably disposed on the lower mold 200. Exemplarily, a fixed base 330 is provided on the lower mold 200, and the support base 310 is height-adjustably disposed on the fixed base 330. For example, the fixed base 330 is provided with a slotted hole, the extension direction of which is parallel to the height direction of the fixed base 330. The support base 310 is locked in different positions within the slotted hole by a locking member to fix the support base 310 at different heights. The locking member is a screw.

[0032] By adjusting the height of the support base 310 on the lower mold 200, and by allowing the clamping assembly 400 to rotate, while maintaining a gap between the support base 310 and the clamping assembly 400, the upper and lower surfaces of the bright trim strip 600 can be shaped by adjusting the height of the support base 310 relative to the lower mold 200.

[0033] Please see Figure 1 , Figure 2 and Figure 3 According to some embodiments of this application, optionally, the torsion assembly 500 includes a first mounting base 510, a rotating shaft 520, and a torsion drive. The first mounting base 510 has a through hole for the rotating shaft 520 to pass through, and the rotating shaft 520 is rotatably connected in the through hole. One end of the rotating shaft 520 is connected to the clamping assembly 400. The torsion drive is connected to the rotating shaft 520 and is used to drive the rotating shaft 520 to rotate.

[0034] The rotating shaft 520 is rotated at any angle by the torsion drive, thereby causing the clamping assembly 400 to rotate at any angle.

[0035] Please see Figure 1 , Figure 2 and Figure 3 According to some embodiments of this application, optionally, the torsion drive includes a second mounting base 530, a rack 540 and a gear 550. The rack 540 is height-adjustably disposed on the second mounting base 530, and the gear 550 is disposed at one end of the rotating shaft 520 away from the clamping assembly 400. The gear 550 is meshed with the rack 540.

[0036] By adjusting the height of the rack 540 relative to the second mounting base 530, the rotation angle of the gear 550 can be adjusted. When the gear 550 rotates, the rotating shaft 520 rotates along with the gear 550, thereby driving the clamping assembly 400 to rotate at any angle.

[0037] Please see Figure 1 , Figure 2 and Figure 3 According to some embodiments of this application, optionally, the first mounting base 510 is provided with two through holes, each through hole is provided with a rotating shaft 520, and both rotating shafts 520 are provided with gears 550, which are meshed together. One of the two rotating shafts 520 is connected to the clamping assembly 400, and the gear 550 on the other rotating shaft 520 is meshed with a rack 540.

[0038] Two perforations are arranged side by side. A clamping assembly 400 is provided on a rotating shaft 520 located away from the rack 540, and a gear 550 on a rotating shaft 520 located close to the rack 540 meshes with the rack 540. By adjusting the height of the rack 540 relative to the second mounting base 530, the gear 550 on the rotating shaft 520 located close to the rack 540 can be rotated, thereby rotating the gear 550 on the rotating shaft 520 located away from the rack 540, thereby rotating the clamping assembly 400, so as to cause the bright trim strip 600 to twist inward. This application does not require mold surface reduction compensation processing, and the structure is relatively simple and easy to operate, which can reduce the occurrence of abnormalities and the number of repairs of the bright trim strip folding mold 10.

[0039] Please see Figure 1 , Figure 2 and Figure 3 According to some embodiments of this application, the rotating shaft 520 may optionally be detachably connected to the clamping assembly 400.

[0040] By detachably connecting the rotating shaft 520 to the clamping assembly 400, when it is necessary to twist the bright trim strip 600 inward, the clamping assembly 400 can be set on the rotating shaft 520 away from the rack 540, and when it is necessary to twist the bright trim strip 600 outward, the clamping assembly 400 can be set on the rotating shaft 520 close to the rack 540. The corresponding rotating shaft 520 can be selected according to the usage requirements.

[0041] Please see Figure 1 , Figure 2 and Figure 3 According to some embodiments of this application, optionally, the rack 540 is movably disposed on the second mounting base 530. Specifically, the second mounting base 530 is provided with a sliding groove, and the rack 540 is slidably connected in the sliding groove.

[0042] The upper mold 100 is provided with a connecting plate 560 having a connecting hole, into which an adjusting bolt 570 is threaded. The adjusting bolt 570 can abut against the top of the rack 540. A reset member 580 is provided between the bottom of the rack 540 and the second mounting base 530. The reset member 580 is used to provide a reset force to keep the rack 540 in its initial state. The reset member 580 is a spring.

[0043] By rotating the adjusting bolt 570 downwards, the adjusting bolt 570 abuts against the top of the rack 540, causing the rack 540 to move downwards. By rotating the adjusting bolt 570 upwards, the rack 540 can be moved upwards under the action of the reset member 580. By rotating the adjusting bolt 570 and under the action of the reset member 580, the height of the rack 540 relative to the second mounting base 530 can be adjusted.

[0044] Please see Figure 1 , Figure 2 and Figure 3 According to some embodiments of this application, optionally, the horizontal height of the bottom plane of the connecting plate 560 is higher than the horizontal height of the bottom plane of the pressure member 320. When the upper mold 100 moves in the approach direction, the pressure member 320 first presses the bright trim strip 600 to be shaped against the support base 310, and then adjusts the height of the rack 540 relative to the second mounting base 530 by adjusting the adjusting bolt 570.

[0045] Please see Figure 1 , Figure 2 and Figure 3 According to some embodiments of this application, optionally, the clamping assembly 400 includes a first clamping block 410 and a second clamping block 420, the first clamping block 410 and the second clamping block 420 being able to move away from or close to each other to release or clamp the bright trim strip 600.

[0046] The first clamping block 410 forms a mounting platform with a first mounting hole. The second clamping block 420 has a second mounting hole. A mounting screw passes through the second mounting hole and is threadedly connected to the first mounting hole. Specifically, the mounting screw is threadedly connected to the first mounting hole.

[0047] By tightening the mounting screws, the first clamping block 410 and the second clamping block 420 can be brought closer together to clamp the bright trim strip 600. By releasing the mounting screws, the first clamping block 410 and the second clamping block 420 can be moved away from each other to release the bright trim strip 600.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
