Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and more specifically, to a forked pin stamping die. Background Technology

[0002] A bifurcated needle is a type of needle with multiple needle tips at one end, such as a tattoo needle. During production, bifurcated needles require processing using a stamping die. According to Chinese Patent CN201921301777.6, a tattoo needle stamping die includes a base and a buffer plate vertically sliding on the base. The bottom of the buffer plate is mounted on the base via a buffer assembly. A forming mechanism is located on the base corresponding to the position above the buffer plate. The forming mechanism includes multiple die seats stacked on the base, each die seat equipped with a stamping assembly. This invention has a simple structure, is easy to use, has a fast processing speed and good processing accuracy, and can complete the stamping of multiple tattoo needles at once, greatly improving the processing efficiency. By stacking multiple die seats on the base, simultaneous processing of multiple tattoo needles is achieved. The grooves on the die seats, together with the U-shaped grooves on the stamping plate, can restrain the tattoo needle, greatly reducing the possibility of misalignment or bending of the tattoo needle preform. Existing stamping dies generate stamping waste that is difficult to remove from the stamping cavity during use, causing inconvenience.

When the guide column 8 moves downward, it drives the buffer plate 24 to move downward. When the buffer plate 24 moves downward, it will squeeze the buffer spring 26 to achieve a buffering effect. By setting the buffer assembly, a certain buffering effect can be achieved during stamping to prevent the excessive stamping force from damaging the mold.

[0032] In practical applications, when cleaning the stamping groove 5 is required, rotating the wheel 20 drives the lead screw 14 to rotate. The lead screw 14 drives the moving block 15 to move away from the wheel 20. At this time, the moving block 15 pulls the two sets of sliding plates 16 to move closer together through the movable support rod 17. The sliding plates 16 drive the limiting post 18 to disengage from the limiting groove 19 on the sliding mold 4 and enter the adjusting groove 13. At this time, the limiting of the sliding mold 4 is released, and the personnel can pull the pull ring 22 to pull the sliding mold 4 out of the mounting groove 3. By setting the sliding mold and the limiting component, it is convenient for personnel to clean the waste in the stamping groove. The limiting component is connected by the lead screw, moving block, slide table, sliding plate, and movable support rod 17. The moving support rod and the limiting column work together to limit the sliding mold. The operation is simple and the disassembly and assembly are convenient, thereby improving the cleaning efficiency of the stamping groove. When stamping, the connecting plate 10 is connected to the external stamping equipment. The external stamping equipment drives the guide column 8 to move downward through the connecting plate 10. The guide column 8 drives the stamping plate 9 to move downward. The stamping plate 9 drives the stamping part 12 to move downward for stamping. When the guide column 8 moves downward, it drives the buffer plate 24 to move downward. When the buffer plate 24 moves downward, it will squeeze the buffer spring 26 to achieve a buffering effect. By setting the buffer component, a certain buffering effect can be achieved during stamping to prevent the mold from being damaged due to excessive stamping force.

[0033] In summary, by utilizing the above-mentioned technical solution of this utility model, the sliding mold and the limiting component facilitate the cleaning of waste in the stamping groove by personnel. The limiting component, through the cooperation of the lead screw, moving block, slide table, slide plate, movable support rod and limiting column, limits the sliding mold. It is simple to operate and easy to disassemble and assemble, thereby improving the cleaning efficiency of the stamping groove. The buffer component can play a certain buffering role during stamping, preventing excessive impact force from damaging the mold.
