[0023] Mold closing process: When the punch press moves downward, it pushes the die handle 1, the upper die seat 13, the pad 14, the first cutting edge 15, and the positioning core 16 to move downward. At the same time, the upper guide sleeve 2, the guide column 8, and the lower guide sleeve 9 play a guiding and supporting role, and the guide pin 3 plays a guiding role. The thread 6 enters the product part 5 to fix it. The entire upper die pushes the product part 5 to move downward, first enters the second cutting edge 17, then presses the support plate 22, and then the support plate 22 pushes the movable slider 18 to move downward. The fixed seat 19 plays a fixing role on the fixed slider 7. When the movable slider 18 and the fixed slider 7 are in contact, the two surfaces that the two sliders first contact make the movable slider 18 move, and the movable slider 18 drives the second cutting edge 17 to move up, left, down, and right. At the same time, the positioning core 16 remains horizontal and does not move, fixes the product part 5, and then the first cutting edge 15 and the second cutting edge 17 cooperate with each other to trim the product part 5.

[0024] Reset process: When the punch press moves upward, it pulls the die handle 1, the upper die seat 13, the pad 14, the first knife edge 15, and the positioning core 16 to move upward. After the support plate 22 has no downward pressure, the bottom plate 12 is used as the force-bearing point, and the rubber 21 pushes the support plate 11, the reset push rod 20, the support plate 22, and the movable slide block 18 upward in turn to complete the reset.

[0025] like Figures 1 to 4 As shown, the surface of the upper guide sleeve 2 is provided with a limiting groove, and a guide column 8 is provided inside the limiting groove. The size of the limiting groove is adapted to the size of the guide column 8. Positioning grooves are provided on both sides of the surface of the positioning core 16. The size of the positioning grooves is adapted to the size of the equal-height thread 4. Arc blocks are provided on the four sides of the movable slider 18, and the surface of the arc blocks is in contact with the four sides of the surface of the product part 5.

[0026] During use, personnel can connect the upper guide sleeve 2 and the guide column 8 , the guide column 8 supports the upper guide sleeve 2 , and personnel can install the positioning core 16 through the equal-height thread 4 .

[0027] The working principle and use process of the utility model are as follows: during the mold closing process, when the punch press moves downward, it pushes the mold handle 1, the upper mold base 13, the pad 14, the first blade 15, and the positioning core 16 to move downward. At the same time, the upper guide sleeve 2, the guide column 8, and the lower guide sleeve 9 play a guiding and supporting role, and the guide pin 3 plays a guiding role. The thread 6 enters the product part 5 for fixing. The entire upper mold pushes the product part 5 to move downward, first enters the second blade 17, presses the support plate 22, and then the support plate 22 pushes the movable slider 18 to move downward. The fixed seat 19 plays a fixing role on the fixed slider 7. When the movable slider 18 and the fixed slider 7 are in contact, the two surfaces of the two sliders first contact to cause the movable slider 18 to move, and the movable slider 18 drives the second blade 17 to move up, left, down, and right. At the same time, the positioning core 16 keeps the horizontal plane motionless, fixes the product part 5, and then the first blade 15 and the second blade 17 cooperate with each other to trim the product part 5. Then reset is carried out. During the reset process, the punch press moves upward, pulling the die handle 1, the upper die seat 13, the pad 14, the first cutting edge 15, and the positioning core 16 upward. After the support plate 22 has no downward pressure, the bottom plate 12 is used as the force-bearing point, and the rubber 21 pushes the support plate 11, the reset push rod 20, the support plate 22, and the movable slide block 18 upward in sequence to complete the reset.
