[0024] Working principle: When performing the stamping work, first connect the entire device to the external safe mains power, then place the sole raw material that needs to be stamped on the sole mold 2, and then align the guide slide 10 on the sole mold 2 with the sole placed on it with the guide slide 9, and slide it between the two guide slides 9; after the sole mold 2 is placed on the guide slide 9 on the mold base, first control the first servo motor 12 to start, and after the first servo motor 12 is started, it will drive the first ball screw 11 to rotate, and after the first ball screw 11 rotates, it will drive the nut seat to move to one side, and during the movement of the nut seat, it will drive the mold base and The sole mold 2 with the sole placed on the mold base moves together; when the mold base with the sole placed moves to the opposite side of the stamping frame 3 (that is, the sole mold 2 is just located between the stamping block 5 and the material shifting pusher 19, and the limit guide rail 6 and the guide slide rail 9 at the corresponding position are connected), the other nut seat (during the loading process, the sole mold 2 is first placed on one of the nut seats, and the other nut seat is in an empty state) will contact with the limit stopper 13 on one side and press the limit switch 14 on the limit stopper 13. After the limit switch 14 is pressed, the first servo motor 12 will be controlled to stop, thereby stopping the sole mold 2 from moving.

[0025] Then, the second servo motor 16 is controlled to start and the circuit between the energized coil 21 and the power supply is connected. After the second servo motor 16 is started, it will drive the second ball screw 15 to rotate. After the second ball screw 15 rotates, it will drive the material shifting base 17 to move toward the punching frame 3. During the movement of the material shifting base 17, the material shifting baffle 18 and the material shifting pusher 19 will move together. In the process of the material shifting base 17 driving the material shifting pusher 19 to move, each material shifting pusher 19 will contact the side of the sole mold 2 at the corresponding position through the through slot on the auxiliary part and push The sole mold 2 moves along the guide rail 9 toward the stamping frame 3. Because the guide rail 9 is connected to the limit rail 6, the sole mold 2 will enter between the two limit rails 6 along the guide rail 9 under the action of the material moving pusher 19, and finally move to the bottom of the stamping block 5, and the side of the sole mold 2 contacts the positioning stopper 7; when the sole mold 2 contacts the positioning stopper 7, the pressure sensor 8 on the positioning stopper 7 will generate a signal and send it to the external controller (the controller here is set on the side of the workbench 1, specifically A programmable controller of the type FX2C-20MRD, Cortex-R8, or Cortex-M7 can be used; at the same time, the pressure sensor in the utility model can specifically adopt the type PX309-200A5V, PXM600MU-350BARGV or PXM600MU-70BARGV). After receiving the electrical signal sent by the pressure sensor 8, the controller will determine that the sole mold 2 has moved into place, thereby controlling the second servo motor 16 to stop, and controlling the stamping cylinder 4 to start, and the stamping cylinder 4 will be pressed. After being started, the punching block 5 is driven to move toward the sole mold 2, so that the punching block 5 and the sole mold 2 cooperate to complete the punching work on the sole inside. At the same time, because the energized coil 21 is energized and started, a magnetic field is formed around the energized coil 21. When the material-moving pusher 19 contacts the side of the sole mold 2, under the action of the magnetic field around the energized coil 21, the material-moving pusher 19 is attracted together through the iron sheet 2 on the side of the sole mold 2, so that the material-moving pusher 19 can be stably connected to the sole mold 2 during the pushing process.

[0026] After the stamping is completed, the stamping cylinder 4 is controlled to stop first. After the stamping cylinder 4 stops, the stamping block 5 will be driven to move upward, thereby separating the stamping block 5 from the sole mold 2; then the second servo motor 16 is controlled to start in the reverse direction. After the second servo motor 16 is started in the reverse direction, the second ball screw 15 will be driven to rotate again, thereby making the material moving base 17 move along the stamping frame 3 toward the direction of the second servo motor 16. During the movement of the material moving base 17, the material moving pusher 19 will drive the sole mold 2 that has completed the stamping work to move back together. During the movement, the sole mold 2 will move along the limiting guide rail 6 and the guide slide rail 9 to the mold base. Wait until the sole mold 2 is completely back to the mold base When the shoe sole mold 2 is on the tool base, the material moving push piece 19 will continue to move back. During this process, the material moving push piece 19 will move from between the two guide rails 9 to one side of the guide rail 9 through the through groove on the auxiliary part; and because the blocking effect of the auxiliary part can block the movement of the sole mold 2, the sole mold 2 stops moving. During this process, the material moving push piece 19 will be separated from the sole mold 2 under the blocking effect of the auxiliary part (at the same time, this process can also be achieved by manually controlling the power-on coil 21 to be de-energized after the sole mold 2 enters the material moving device, or by setting the program to control the power-on coil 21 to be de-energized after a certain period of time after the second servo motor 16 starts in the reverse direction), and finally the material moving push piece 19 returns to the initial position. Position, and the sole that has completed the stamping work will return to the mold base along with the sole mold 2; then the second servo motor 16 is controlled to stop, and the first servo motor 12 is controlled to move in the opposite direction. After the first servo motor 12 is started in the reverse direction, it will drive the nut seat to move towards the initial position. During the movement of the nut seat, the mold base and the sole mold 2 on the mold base will be driven to move together, and finally the sole that has completed the stamping work will be moved to the initial position; and the other mold base that has completed the loading work will move to the opposite side of the stamping frame 3, waiting for the next group of sole stamping work; because there are two mold bases, when the sole is stamping on one of the mold bases, the operator The operator can place the latter group of soles that need to be stamped on the empty sole mold 2 and put it into the mold base; similarly, when the soles on the latter group of mold base are being stamped, the operator can take out the soles of the previous group that have completed the stamping work from the sole mold 2, and put in new soles to wait for the next stamping work; when the stamping block 5 is damaged or the stamping pattern needs to be replaced, the stamping block 5 can be removed from the stamping base by rotating the stamping block 5, because the stamping block 5 is threadedly connected to the thread groove 23 through the connecting seat 24. During the rotation of the stamping block 5, the connecting seat 24 will rotate with the stamping block 5, which is very convenient to replace.
