Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a structure for quickly removing scrap from a stamping die. Background Technology

[0002] Stamping is a process that uses stamping dies to apply pressure to metal sheets, causing them to undergo plastic deformation and achieve the desired shape. The entire process is usually carried out on a press, where the press provides the pressure and the stamping die performs the specific forming operation. Stamping dies are tools used in the stamping process to help deform metal sheets through the pressure of the die, thereby obtaining the required shape and size. Stamping dies are usually made of steel, possessing high wear resistance and strength, and are widely used in the automotive, home appliance, and electronics industries to produce various precision parts. After stamping, scrap may remain in the die, requiring a structure that can quickly remove the scrap. Timely and effective removal of scrap not only avoids scrap accumulation but also reduces the risk of die damage and improves product quality.

[0003] A search revealed Chinese Patent Publication No. CN214683748U, which discloses a structure for quickly removing scrap from a stamping die. The structure includes upper and lower dies. A female punch is mounted on the upper die and positioned between the upper and lower dies, aligned with the cutting edge of the lower die. A blind hole is provided within the female punch, and a male punch is positioned within the blind hole. One end of the male punch is confined within the blind hole, and the other end extends to the end of the female punch near the lower die. A spring is also provided within the blind hole, and the male punch is located within the extension path of the spring. A screw is provided at the end of the blind hole away from the lower die, confining the spring within the blind hole. When the female punch finishes stamping the material within the cutting edge of the lower die and moves upward, the male punch, due to the spring's action, pushes downward out of the female punch, removing the scrap from the female punch and preventing further adhesion to the cutting edge. While it can extend the service life of the cutting edge to a certain extent, it is difficult to remove all the residual material completely and intact by the inertial force of stamping alone, and smaller waste materials cannot be effectively removed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a structure for quickly removing scrap from stamping dies, aiming to improve the problem in the prior art that it is difficult to completely remove all residual material, and small scrap cannot be effectively removed.

[0047] Working principle: The lower mold 1 and the upper mold 9 are connected by sliding column 12 and grooved column 13. When the press presses the mold downward, residual material will remain on the shear cylinder 18, affecting the next mold forming and reducing the service life of the shear cylinder 18. The limiting cylinder 3 has a limiting groove 4 to allow the strong spring 5 to extend and retract inside. The press rod presses against the elastic plate 8, and the pressure column 7 and slider 6 apply pressure to the strong spring 5. After the mold is compressed, the strong spring 5 returns to its elasticity and ejects the waste material remaining on the inner wall of the shear cylinder 18. The quick removal of waste material can quickly clean up the waste material after each press, reducing downtime caused by waste material jamming. The mold can complete the next press operation more efficiently, increasing the press speed and thus increasing output. The quick removal of waste material avoids the waste material remaining in the mold for too long, reduces the friction of waste material on the mold surface, and reduces the risk of mold wear.

[0048] To facilitate the replacement of different molds, the convenient installation mechanism 2 on the outer wall of the stamping column 10 allows for easy disassembly and installation. The bottom of the fixing plate 201 is aligned with the top of the upper mold 9, aligning the threaded hole 202 with the threaded opening 205. The fixing bolt 203 passes through the threaded hole 202 and the threaded opening 205, penetrating the fixing plate 201 and the upper mold 9. Finally, the anti-loosening nut 204 is tightened for reinforcement, thus completing the installation of the mold and the stamping column 10. Repeating this operation completes the disassembly and replacement. The rapid installation and disassembly of the stamping mold reduces production line downtime. When the mold needs to be replaced, a new mold can be quickly disassembled and installed, which helps improve the continuity and stability of production, reduces the time required for mold replacement, and enables the production line to operate more efficiently.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
