[0030] A reinforcing connecting rod 25, which is welded on the inner wall at the bottom end of the installation inner groove 13, and a head seat 21 is integrally formed at one end of the reinforcing connecting rod 25, and a clamping block 20 is integrally formed at one end of the head seat 21, and one end of the clamping block 20 is in contact clamping connection with the top support plate 19;

[0031] An electromagnet 24, which is embedded in the inner wall at one end of the clamping block 20, and the electromagnet 24 is in adsorption connection with the top support plate 19.

[0032] During use, the top plate and the stamping die head are pulled back by the hydraulic cylinder, and then the closing switch button is pressed, so that the electromagnet is disconnected from the power supply. At this time, the electromagnet loses its magnetic force and can no longer adsorb and fix the top support plate. The return spring in a state of contraction deformation drives the top support plate to lift, thereby ejecting the filling block from the inside of the forming groove, and further ejecting the formed sheet metal part from the inside of the inner template.

[0033] Please refer to Figure 1 and Figure 4 , a switch button 9 is arranged on the outer wall of one side of the mold frame 5. Power supply wires 10 are respectively arranged on the output end and the input end of the switch button 9. A connection plug 11 is arranged at one end of one power supply wire 10, and the other power supply wire 10 is electrically connected to the input end of the electromagnet 24. The switch button 9 arranged on the outer wall of one side of the mold frame 5 functions to control whether to be powered on.

[0034] Please refer to Figure 1 and Figure 3 , an integral connecting rod 23 is welded at the lower end of the top plate 6. A stamping die head 12 is welded at one end of the integral connecting rod 23. The size of the stamping die head 12 is equal to the caliber of the inner template 14 and the forming groove 15. The integral connecting rod 23 welded at the lower end of the top plate 6 functions to connect the stamping die head 12 and the top plate 6.

[0035] Please refer to Figure 1, there are connecting sleeve rods 7 and guiding sleeve rods 8 provided between the top platen 6 and the mold frame 5. There are four connecting sleeve rods 7 and four guiding sleeve rods 8 respectively. Adjacent two connecting sleeve rods 7 and guiding sleeve rods 8 are sleeved and connected. The connecting sleeve rods 7 and guiding sleeve rods 8 provided between the top platen 6 and the mold frame 5 play a role in guiding and connecting the top platen 6 and the mold frame 5.

[0036] Please refer to Figure 2 , there are support angle blocks 18 welded on the bottom inner wall of the forming groove 15. There are four support angle blocks 18, and the four support angle blocks 18 are respectively located at the four corner positions of the inner wall of the forming groove 15. The support angle blocks 18 welded on the bottom inner wall of the forming groove 15 play a role in limiting and supporting the filling block 16.

[0037] Please refer to Figure 2 , there are four mounting holes 3 provided inside the base plate 2. Both sides of the return spring 22 are provided with connecting rods 4. The two ends of the connecting rod 4 are respectively welded and connected to the base plate 2 and the mold platform 1. The four mounting holes 3 provided inside the base plate 2 play a role in facilitating the grounding installation of the base plate 2.

[0038] Please refer to Figure 1 , there is a hydraulic connector 17 provided on the top of the top platen 6. The hydraulic connector 17 and the top platen 6 are of an integral structure. The hydraulic connector 17 provided on the top of the top platen 6 plays a role in facilitating the insertion and connection of the piston rod of the hydraulic cylinder.

[0039] Working principle: When in use, the base plate 2 is installed below the hydraulic cylinder by screws, and the piston rod of the hydraulic cylinder is inserted into the inside of the hydraulic connector 17 and fixed by gluing. Then, the inner template 14 is installed inside the installation inner groove 13 by screws, and the top support plate 19 is made to contact the lower end surface of the filling block 16. Then, the connection plug 11 is connected to the power supply, so that the electromagnet 24 generates an adsorption force to adsorb the top support plate 19 after being electrified. At this time, the return spring 22 is in a contracted deformation state. Then, a metal thin plate with the same caliber size as the inner template 14 is placed into it. Then, the hydraulic cylinder pushes the top platen 6, so that the stamping die head 12 is inserted into the inside of the inner template 14, and the metal thin plate is stamped to generate deformation, thereby being processed into a sheet metal part structure with a groove. After the processing is completed, the hydraulic cylinder pulls the top platen 6 and the stamping die head 12 back to their original positions. Then, the shutdown switch button 9 is pressed, so that the electromagnet 24 is disconnected from the power supply. At this time, the electromagnet 24 loses its magnetic force and can no longer adsorb and fix the top support plate 19. The return spring 22 in the contracted deformation state drives the top support plate 19 to lift, thereby pushing the filling block 16 out of the inside of the forming groove 15, and further pushing the formed sheet metal part out of the inside of the inner template 14, achieving the purpose of facilitating the material taking after stamping and forming processing, and completing the use work of the sheet metal part stamping die.
