The guide mechanism 43 is arranged around the lifting cylinder 41, and the waste discharge sleeve is arranged through the guide mechanism 43.

[0076] Specifically, Fig.11 As shown, the lower workbench 12 is provided with an installation space (such as a U-shaped groove in the figure), and the lifting mechanism includes a lifting electric cylinder 41 and a guide mechanism 43. The lifting mechanism is fixedly connected to the waste discharge sleeve, and can lift or lower the waste discharge sleeve, and can achieve docking or separation of the waste discharge sleeve with the middle waste discharge hole 223 on the middle mold frame 22, so that it is convenient to replace the middle mold frame 22. The guide mechanism 43 is arranged around the lifting electric cylinder 41, and the waste discharge sleeve passes through the guide mechanism 43. In this way, when the lifting electric cylinder 41 pushes the waste discharge sleeve to run, the guide mechanism 43 plays a guiding role, ensuring the stable operation of the waste discharge sleeve, and making the waste discharge sleeve stably docked with the middle mold frame 22.

[0077] In some embodiments, the guide mechanism 43 includes a plurality of guide rods 431, a connecting plate and a limiting plate 432, the connecting plate is sleeved on the guide rod 431, the limiting plate 432 is fixed on the end of the guide rod 431, the waste discharge sleeve passes through the connecting plate and the limiting plate 432 in sequence, and the side wall of the waste discharge sleeve is fixed to the connecting plate.

The four corners of the connecting plate are respectively sleeved on the corresponding guide rods 431. The connecting plate is provided with a guide sleeve 34 (a T-shaped part on the front in the figure) that matches the guide rod 431, so that the connecting plate is easy to move on the guide rod 431. The waste discharge sleeve passes through the connecting plate and is fixedly connected to the connecting plate. In this way, when the lifting cylinder 41 pushes the waste discharge sleeve to move, the connecting plate and the guide rod 431 can play a guiding role. The limit plate 432 is arranged on the top of the guide rod 431 to prevent the connecting plate from being lifted too high and separated from the guide rod 431.

[0079] The specific stamping process is as follows:

[0080] In the present invention, the upper workbench 11 can be moved up and down, and adopts the existing punching machine lifting mechanism, which will not be described in detail in the present invention. First, the workbench is reset, the leather to be punched is taken, the leather and the upper template 32 are installed on the slide rail 311 on the upper pressing plate 31, and then the leather and the upper template 32 are pressed by the clamping device 331; the upper mold assembly 3 is installed.

[0081] First, after the locking mechanism 021 on each installation station is initially adjusted to a suitable position by a control system (for example, the control system uses an existing PCU), the lower mold frame 21 is installed between the locking mechanisms 021, that is, the fixing block 0217 on the lower mold frame 21 is installed on the boss 0216 on the push plate (such as Figure 5 and Figure 6 , the boss 0216 can be of any shape, and the fixing block 0217 is set to a corresponding shape), and then the lower mold frame 21 is fixed by pushing the cylinder, and then the mold is installed. The mold includes a stacked middle mold frame 22, a support plate 23 and a needle plate 24. First, the mold is fixed by bolts, and then the mold is installed on the guide column 212 of the lower mold frame 21. The limit block 224 of the middle mold frame 22 is inserted into the middle mold positioning hole 214 of the lower mold frame 21 to stably install the mold. The installation of the lower mold assembly 2 is completed. The driving motor 041 of the driving device 04 drives the screw 042 to rotate, and the screw 042 drives the die set mounting frame 02 to move on the guide rail 033, so that each station cooperates with the upper die set 3; the lower die set 2 that needs to be punched is moved to the punching equipment 01; then the lifting electric cylinder 41 is driven to push the waste discharge sleeve upward, so that the connection port 422 of the waste discharge sleeve is connected with the middle waste discharge hole 223 in the middle of the middle die frame 22, and the residual material after punching is discharged through the waste discharge sleeve during the working process. If the mold needs to be replaced, the middle die frame 22 can also be lifted up to move the middle die frame 22 upward and separate from the lower die frame 21 for replacement.
