The second horizontal driving member is connected with the second guide rail and can drive the second guide rail to move horizontally along the second guide rail.

[0052] The first guide rail and the second guide rail can move relatively close to or away from each other. When the first guide rail and the second guide rail move away from each other, a space can be reserved between the first guide rail and the second guide rail for the mold frame 200 to accommodate the mold set 300 to move up and down in the cavity without interference. When the required mold set 300 reaches the designated area, the first guide rail and the second guide rail move close to each other.

A controller is electrically connected with the electromagnet 580 and is used to control the power-on or power-off of the electromagnet 580. When the third driver 570 extends, the electromagnet 580 can push the mold set 300 to move from the designated position to the first locking member 400. When the third driver 570 retracts and the electromagnet 580 is powered on to attract the mold set 300, the electromagnet 580 can grasp the mold set 300 to move from the first locking member 400 to the designated position.

[0056] In the above embodiment, it can be known that the first conveying member can only output the required mold set 300 to the specified position, and no power is continued to enter the first locking member 400. The third driver 570 and the electromagnet 580 are moved up and down to a position where the electromagnet 580 horizontally faces the required mold set 300. The electromagnet 580 is driven forward by the third driver 570 at this time, and the electromagnet 580 is not powered. The electromagnet 580 is directly driven by the third driver 570 to resist the mold set 300, and the mold set 300 is pushed into the first locking member 400 from the specified position.

The third driver 570 continues to drive the electromagnet 580 to retract to the original position. By adjusting the height position of the accommodation cavity of the mold rack 200, the mold set 300 to be retracted is opposite to the corresponding accommodation cavity. The mold set 300 to be retracted can be retracted into the corresponding accommodation cavity by the first conveying member, so as to be used for subsequent replacement.

The third slide groove is arranged on the third slide rail, and the fourth slide groove is arranged on the fourth slide rail. The third driving module and the fourth driving module can be air cylinders, oil cylinders or electric cylinders, etc. Both of them can be installed on the stamping part 600 by bolts. The third driving module is connected to the third support, and is used to drive the third support to move back and forth. The fourth driving module is connected to the fourth support, and is used to drive the fourth support to move back and forth. Thus, different sizes of the die set 300 can be adapted, and after the stamping part 600 moves to a specified height, the corresponding third support and fourth support can be inserted below the upper die 310 or released from the upper die 310 by controlling the third driving module and the fourth driving module, so that the upper die 310 can be locked or unlocked.

[0074] In some embodiments, the first support 410 and the second support 420 are fixedly arranged on the rack 100, and the third support and the fourth support are fixedly arranged on the stamping part 600. Before replacing the required die set 300, the second locking piece 700 is first moved downward to a specified height by the stamping part 600.
