[0035] In the operation of this embodiment:

[0036] During die change, the slide block 13 moves downward along the frame 12, causing the upper die 2 to fit with the lower die 3, and the locking device 4 between the upper die 2 and the lower die 3 is locked. The locking device 4 between the first combined plate 21 and the third combined plate 131 is unlocked, and the locking device 4 between the second combined plate 31 and the fourth combined plate 111 is unlocked. The air cylinder 52 contracts, driving the third combined plate 131 away from the first combined plate 21 and driving the fourth combined plate 111 away from the second combined plate 31, separating the socket 8 from the interface 7. The clamping device 14 of the workbench 11 releases the lower die 3, the slide block 13 drives the upper die 2 and the lower die 3 to move upward, the die change cart enters the workbench 11, the slide block 13 moves downward, the clamping device 14 of the slide block 13 releases the upper die 2, and the die change cart replaces the die.

[0037] After the die change cart transports the new die in place, the slide block 13 moves downward, the clamping device 14 of the slide block 13 clamps the upper die 2, and the slide block 13 drives the new die to move upward. After the die change cart leaves, the slide block 13 moves downward until the new die fits with the workbench 11. The clamping device 14 of the workbench 11 clamps the lower die 3, and the locking device 4 between the upper die 2 and the lower die 3 is unlocked. The air cylinder 52 extends, driving the third combined plate 131 to approach the first combined plate 21 and driving the fourth combined plate 111 to approach the second combined plate 31, so that the socket 8 is inserted into the interface 7. The locking device 4 between the first combined plate 21 and the third combined plate 131 is locked, and the locking device 4 between the second combined plate 31 and the fourth combined plate 111 is locked. The slide block 13 moves upward to complete the die change.

[0038] In this embodiment, by connecting the pipeline of the hydraulic press 1 to the third combined plate 131 at the front end of the slide block 13 and the fourth combined plate 111 at the front end of the workbench 11, the locking or unlocking of the locking device 4 between the first combined plate 21 and the third combined plate 131 realizes the connection and disconnection of the pipeline of the hydraulic press 1 and the upper die 2, and the locking or unlocking of the locking device 4 between the second combined plate 31 and the fourth combined plate 111 realizes the connection and disconnection of the pipeline of the hydraulic press 1 and the lower die 3. Then, through the disassembly between the slide block 13 and the upper die 2, the disassembly between the workbench 11 and the lower die 3, and the locking of the upper die 2 and the lower die 3, the die is separated from the hydraulic press 1. Through the connection between the slide block 13 and the upper die 2, the connection between the workbench 11 and the lower die 3, and the unlocking of the upper die 2 and the lower die 3, the upper die 2 of the hydraulic press 1 is realized. The structure is simple, the pipeline insertion efficiency is high, the die installation and replacement efficiency is high, and the whole process is automated die change with high safety.
