After searching, a Chinese patent with the authorization number CN216705694U discloses a hardware stamping die. Although the device moves downward in the groove by the gravity of the push plate itself, pushing out the parts stuck on the outer wall of the punch and dropping them from the punch, reducing the trouble of manual removal and improving the convenience of use and work efficiency, burrs often appear on the edges of the stamped hardware, which requires further manual grinding of the parts, thereby extending the process and reducing production efficiency.

Four positioning rods are provided, and the four positioning rods are respectively welded to the four ends of the bottom of the upper module. The bottom of the positioning rod is in a conical structure. The positioning rods are used to facilitate the insertion of the positioning rods into the positioning grooves when the upper module is lowered and fits with the lower die base, which facilitates the alignment of the upper die base and the lower die base, thereby improving the accuracy of stamping.

[0006] Preferably, a circular through hole is opened at the bottom end of the base, and connecting bolts are inserted into the through holes at the four ends of the base. The bottom of the connecting bolts is threadedly connected to the device body. By removing the connecting bolts, the base can be removed from the surface of the device body, which is convenient for replacing mold grooves of different shapes, and the telescopic end at the bottom of the hydraulic cylinder and the upper mold base are also detachably connected.

[0009] The utility model provides a precision metal stamping die for burr side cutting, which has the following beneficial effects:

[0010] (1) This is a precision metal stamping die for cutting burrs. When the die is in use, the hydraulic cylinder drives the upper die block to move downward, so that the metal material at the bottom of the lower die block can be stamped. As the upper die block moves downward, the metal material can be stamped into the inside of the die core, thereby obtaining a stamped metal part. As the upper die seat continues to move downward, the upper die seat squeezes the edge material of the part to contact the cutting edge of the die groove edge, so that the burrs on the edge of the stamped part can be removed through the cutting edge of the die core edge, which is beneficial to keep the edge of the stamped part flat and avoid manual burr cleaning, thereby improving production efficiency.

[0011] (2) This kind of burr side cutting precision metal stamping die, after the part is stamped, the high-pressure air is pumped into the air groove through the air rod by an external air pump, so that the high-pressure air inside the air groove can lift the top block, so that the top of the top block can protrude from the surface of the mold core, and then the top block can push out the hardware parts inside the mold core, so as to facilitate removal, thereby improving the convenience of using the mold.

[0012] This solves the problem that the existing stamping die needs to be manually polished to smooth the burrs after stamping out the hardware, which reduces the production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1:

[0021] A burr side cutting precision metal stamping die comprises a device body 1, a base 2, a lower module 3 and a die groove 4. The base 2 is welded on the top of the device body 1, and the lower module 3 is welded on the top of the base 2. The four ends of the device body 1 are welded to one end of the bottom of a support rod 9, and the top end of the support rod 9 is welded to the four ends of a top plate 8. A hydraulic cylinder 7 is installed in the middle of the top plate 8. An upper module 6 is sleeved on the outside of the telescopic end at the bottom of the hydraulic cylinder 7. The bottom of the upper module 6 is aligned with the lower module. The outer side of the lower module 3 is sloped, and a cutting edge is arranged on the top of the sloped structure of the outer side of the lower module 3. As the upper die seat continues to move downward, the upper die seat will squeeze the edge material of the part to contact the cutting edge of the edge of the die groove 4, so that the burrs on the edge of the stamped part can be cut off through the cutting edge of the edge of the core, which is beneficial to keep the edge of the stamped part flat and avoid manual subsequent cleaning of burrs, thereby improving production efficiency.

[0022] Embodiment 2:

[0023] The four ends of the top of the lower module 3 are provided with positioning grooves 11, and the positioning grooves 11 are aligned with the positioning rods 10. There are four positioning rods 10, which are respectively welded to the four ends of the bottom of the upper module 6. The bottom of the positioning rod 10 is in a conical structure. The positioning rod 10 is conducive to the upper module 6 to be inserted into the positioning groove 11 when it is lowered and fits with the lower die base, which is conducive to the alignment of the upper die base and the lower die base, thereby improving the accuracy of stamping.

[0024] Embodiment 3:

[0025] A circular hole groove is provided in the middle of the mold groove 4, and the inside of the circular hole groove inside the mold groove 4 is in sliding contact with the outer wall of the top of the top block 5, the inside of the top block 5 is open, and the inside of the bottom of the top block 5 is in sliding contact with the outer side of the top of the air groove 13, and the inside of the air groove 13 is connected with the gas rod 14, the inside of the gas rod 14 is hollow, and the other end of the gas rod 14 is connected with an external air pump, a cylindrical hole groove is provided at the bottom of the base 2, and the inner wall of the cylindrical hole groove at the bottom of the base 2 is in sliding contact with the outer wall of the top block 5, and when the top block 5 is at the bottom, the top is flush with the surface of the mold groove 4. After the stamping of the parts is completed, high-pressure air is pumped into the air groove 13 through the gas rod 14 by an external air pump, so that the high-pressure air inside the air groove 13 can lift the top block 5, so that the top of the top block 5 can protrude from the surface of the mold core, and then the top block 5 can push out the hardware parts inside the mold core, which is convenient for removal, thereby improving the convenience of using the mold.

[0026] Working principle: When the mold is in use, the upper module 6 is driven by the hydraulic cylinder 7 to move downward, so that the hardware material at the bottom of the lower module 3 can be stamped. As the upper module 6 moves downward, the hardware material can be stamped into the inside of the mold core, thereby obtaining a stamped hardware part. As the upper mold base continues to move downward, the upper mold base will squeeze the edge material of the part to contact the cutting edge of the edge of the mold groove 4, so that the burr on the edge of the stamped part can be removed through the cutting edge of the edge of the mold core. When the part is stamped, high-pressure air is pumped into the air groove 13 through the air rod 14 through an external air pump, so that the high-pressure air inside the air groove 13 can lift the top block 5, so that the top of the top block 5 can protrude from the surface of the mold core, and then the top block 5 can eject the hardware parts inside the mold core.
