A punch is fixed on the lower surface thereof, which corresponds to the position of the mold groove on the lower template on the bottom plate. The punching in the prior art is that the hydraulic lifting device is started to drive the upper template The template and the punch move downward, and the punch punches the plate at the position corresponding to the die groove, and the part falls from the die groove. A lower cavity is opened in the middle of the bottom plate in the front-to-back direction, and the bottom surface of the lower cavity near the opening on the front side is connected to a chip leakage channel. A height adjustment mechanism is arranged at the opening of the lower cavity on the mold body base, and a scraper is installed through it. The height of the scraper is adjusted in advance according to the thickness of the part. A workpiece side clamping structure is provided on the side of the lower cavity, and a push drive is arranged on the bottom surface and a Z-type push plate is installed through it. The Z-type push plate is started by the push drive to push the part out and the stability of the part is maintained under the action of the side clamping structure. When pushing out from the lower cavity opening, the scraper is used to process the surface and burrs on the edges and corners, and the processed debris leaks out from the chip leakage channel.

[0005] As a preferred technical solution of the utility model, the height adjustment mechanism includes a fixed block, a mounting block and an adjusting button. Two fixed blocks are fixed on the upper front side of the mold base. The fixed blocks have through grooves in the left and right directions.

Springs are fixed on the left and right inner walls of the lower cavity. A clamping plate is fixed to the other end of the spring, and its lower surface is in contact with the inner bottom surface of the lower cavity. The inner side of the upper end of the clamping plate has an inner upper chamfered inclined surface, and the inner upper chamfered inclined surface is located below the die groove. The clamping plate is a rigid material. Under the downward pressure of the punch, the part first contacts the side upper chamfered inclined surface, and under the action of the inclined surface, the spring can be squeezed to both sides, and the punch pushes the part until it contacts the inner bottom surface of the lower cavity.

[0007] As a preferred technical solution of the utility model, the pushing drive includes a bottom notch and a screw. The bottom notch is opened in the middle of the bottom surface of the cavity, and the screw is installed in it. The screw is driven by a motor, and one end of the Z-shaped push plate is installed in cooperation with the screw.

[0008] As a preferred technical solution of the utility model, the upper end of the front inner wall of the vertical opening of the chip leakage channel has an inclined chamfer.

[0009] The beneficial effects of the utility model are as follows: the scraper installed by the height adjustment mechanism can adjust the scraper height accordingly according to the different thicknesses of the parts so that the upper surface and the burrs on the corners above the parts can be cleaned in the process of the parts being pushed out by the Z-shaped push plate driven by the push drive, and the arranged push drive and Z-shaped push plate make it easy to take out the parts without reaching into the mold, thereby reducing the operational risks, and the removed debris is discharged through the chip leakage channel without affecting the next part.
