[0064] In one embodiment of the present invention, the movement process of the body panel side shaping mold may be:

[0065] Side shaping movement: The upper slide of the equipment drives the upper die seat 20 downward, and the upper die seat 20 drives the positive press 10, the wedge 30 and the side press 40 downward at the same time. The driving seat 21 first contacts the abutment pad 81 and the buffer block 86, and prompts the driving insert 80 to move downward together. In this process, the driving return nitrogen cylinder 511 is gradually pressed and compressed, and the driving guide plate 84 gradually contacts the driven guide plate 62 to move relative to drive the pulley 60 to move forward. As the movement continues, the movable punch guide plate 63 contacts the pulley punch guide plate 76 and moves relative to drive the movable punch 70 to move in the specified direction. When the punch return nitrogen cylinder 73 contacts the punch return nitrogen cylinder pad 514 and is compressed to its designed stroke, the movable punch 70 stops moving. At this time, the movable punch 70 and the fixed punch 90 are perfectly spliced ​​and the shaping conditions are met. At the same time, as the movement continues, the pulley return nitrogen cylinder 65 contacts the pulley nitrogen cylinder pad 518 and is compressed to its designed stroke, and the pulley 60 stops moving. The drive return nitrogen cylinder 511 also contacts the drive pad 83 and is compressed to its designed stroke, and the drive insert 80 stops moving. As the upper slider of the equipment continues to descend, the positive presser 10 contacts and compresses the fixed punch 90, and further, the inclined wedge 30 contacts the inclined wedge guide plate 23. At the same time, the V-shaped groove of the side shaping guide plate 315 also contacts the corresponding V-shaped sliding part of the lower die seat 50 to drive the inclined wedge 30 to move in the specified direction. The side presser nitrogen cylinder 311 contacts and gradually compresses the side shaping limit block 26. As the movement proceeds, the side presser 40 contacts the movable punch 70, and the side presser nitrogen cylinder 311 is pressurized and compressed. As the movement continues, the side shaping knife block 314 contacts the movable punch 70 and reaches the bottom to complete the shaping work. At the same time, the side presser nitrogen cylinder 311 and the inclined wedge return nitrogen cylinder 318 are compressed to the designed stroke to stop moving. The lower slider of the equipment reaches the bottom dead center, and the entire movement ends. When the side presser 40 is in contact with and pressurized by the movable punch 70, the material flow of the process part 00 during the side shaping process is always effectively controlled to ensure the quality and dimensional accuracy. At the same time, when the side shaping knife block 314 is in contact with the movable punch 70, the side guide plate 317 is in contact with the side seat 25 on the upper die seat 20 and moves relative to each other, so that the lateral force caused by the contact between the side shaping knife block 314 and the movable punch 70 is directly transmitted to the die seat and offset, effectively ensuring the stability of the gap between the side shaping knife block 314 and the movable punch 70, thereby achieving the purpose of stable surface quality and precision of the process part 00. During this process, it is worth noting that when the side presser 40 presses the workpiece and the side shaping knife block 314 contacts the movable punch 70, the side guide plate 317 contacts the side seat 25 at the same time and completes the relative movement synchronously, so as to directly transmit and offset the lateral force generated in the side shaping process to the die base, thereby solving the problem of part fluctuation caused by the unstable gap between the side shaping knife block 314 and the movable punch 70 caused by the lateral force, thereby achieving the purpose of ensuring the quality, precision and stability of the parts.

[0066] Return movement: As the upper die seat 20 is driven back by the slide block on the equipment, the side shaping knife block 314 is separated from the movable punch 70, the inclined wedge return nitrogen cylinder 318 releases pressure to drive the inclined wedge 30 to return, and the side presser nitrogen cylinder 311 releases pressure to drive the side presser 40 to return, and stops returning when they reach the natural state. At the same time, as the upper die seat 20 continues to retreat, the drive seat 21 gradually separates from the drive insert 80, and the drive return nitrogen cylinder 511 releases pressure to make the drive insert 80 return. As the movement continues, the pulley 60 returns and continues to return under the drive of the pulley return nitrogen cylinder 65, and the return of the pulley 60 also drives the return of the movable punch 70, and at the same time, the movable punch 70 continues to return under the drive of the punch return nitrogen cylinder 73, until all return nitrogen cylinders reach the natural state and stop returning.
