The pull rods 307 drive the connecting rods 306 at both ends to move in an arc with the fixed rod 304 as the center of the circle, and the other end of the limiting plate 305 rotates with the fixed rod 304 as the center of the circle, from the inside of the arc-shaped limiting groove 203 to the inside of the movable groove 302 of the clamping plate. At this time, the lower mold 201 is not limited to the limiting plate 306. 05 and the limit rod 308 limit the lower mold can be directly moved upward and taken out for maintenance. This design makes it easy to install and disassemble the lower mold during maintenance, reduces the labor intensity of workers, and saves maintenance time; the limit column 105 limits the upper mold 104 so that it can only move up and down. The limit column 105 is set to a certain length. When the upper mold 104 follows the output end of the electric impact cylinder 103 to move down to the extreme position, the limit column 105 will not separate from the inside of the top of the L-shaped support arm 102.

[0025] In one embodiment, the lower mold assembly 2 includes a lower mold 201, and the four corners of the bottom of the lower mold 201 are each provided with an installation groove 202, one side of the four installation grooves 202 is each provided with an arc-shaped limiting groove 203, and both sides of the lower mold 201 are provided with a limiting hole 204.

[0035] In one embodiment, the surfaces of one end of the two limiting rods 308 are movably embedded in the two limiting holes 204 .

[0036] Specifically: the limiting rod 308 is embedded in the limiting hole 204 to fix the position of the pull rod 307 and the limiting plate 305 to prevent the lower die 201 from moving upward during the stamping operation, causing the limiting plate 305 to passively rotate and detach from the surface of the mounting tube 301.

[0037] Working principle: Connect this hardware continuous stamping die to an external power supply device, the external power supply device is electrically connected to the electric impact cylinder 103 and provides power, the control terminal 101 is electrically connected to the electric impact cylinder 103 and linked to control; this device is used in conjunction with a stamping automatic feeding device, and the electric impact cylinder 103 and the stamping automatic feeding device are started by the control terminal 101, and the stamping automatic feeding device pushes the hardware sheet to the raised surface of the lower die 201, and the electric impact cylinder 103 extends to make the upper die 104 and the lower die 201 cooperate to stamp the hardware sheet, and after the stamping is completed, the electric impact cylinder 103 shortens, and the stamping automatic feeding device pushes the hardware sheet forward to cycle the above operations to connect and stamp the hardware sheet; when maintaining the lower die 201, the handles 310 on both sides of the lower die 201 can be pulled to make one end of the limit rod 308 disengage from the inside of the limit hole 204, and then the pull rods 307 on both sides are pulled upward, and the pull rods 307 drive the connecting rods 306 at both ends to The fixing rod 304 is the center of the circle for arc movement, and the other end of the limiting plate 305 rotates with the fixing rod 304 as the center of the circle, and rotates from the inside of the arc-shaped limiting groove 203 to the inside of the movable groove 302 of the clamping plate. At this time, the lower mold 201 is not limited by the limiting plate 305 and the limiting rod 308 and can be directly moved upward and taken out for maintenance. When installing, pull the handles 310 on both sides and align the four installation grooves 202 of the lower mold 201 with the four installation tubes 301 and put down the lower mold 201.
