[0023] This utility model provides a copper coil ultra-short lead cutting mold, the overall structure of which is exploded as follows: Figure 1 As shown, it includes a left mold assembly 1 and a right mold assembly 4. The structure of the left mold assembly 1 is as follows: Figure 2 As shown, the right mold assembly 4 is as follows Figure 3 As shown. The left mold assembly 1 includes a left mold fixing seat 2 located at the left end. A winding baffle 3 is located on the right side of the left mold fixing seat 2. A cutting groove 32 is machined in the center of the winding baffle 3, and a cutting platform 33 is located inside the cutting groove 32. A winding guide groove 31 is located on the edge of the winding baffle 3, and the winding guide groove 31 extends from the edge of the winding baffle 3 to the cutting groove 32.
[0024] The right mold assembly 4 includes a right mold fixing seat located at the right end. The right mold fixing seat includes a base 5, with mounting holes 51 evenly machined along the edge of the base 5. A connecting seat 6 is located on the left side of the base 5, and a right mold working assembly 7 is mounted on the top left side of the connecting seat 6. The right mold working assembly 7 is as follows: Figure 4 As shown.
[0025] The right mold working assembly 7 includes a cutter top ring 13, which is movably connected to the outer left side of the connecting seat 6 via a keyway 17. A connecting plate 14 is radially fixedly connected inside the cutter top ring 13, and a cutter seat 12 is mounted on the surface of the connecting plate 14. The cutter seat 12 includes a lower cutter fixing seat 1202 and an upper cutter fixing seat 1201. The lower cutter fixing seat 1202 is fixed to the connecting seat 6 by bolts 15, and the upper cutter fixing seat 1201 is connected to the surface of the lower cutter fixing seat 1202. A cutter fixture 8 is mounted on the upper cutter fixing seat 1201.
[0026] A cutter seat limiting block 11, which mates with the cutter seat 12, is installed at the top of the connecting seat 6. A mold core fixing baffle 9 is installed at the top of the cutter seat limiting block 11. A winding mold core 18 is installed in the middle of the mold core fixing baffle 9. Cutter positioning blocks 10 are fixedly connected to the upper and lower sides of the winding mold core 18.

A spring 16 is provided between the cutter positioning block 10 and the lower cutter fixing seat 1102, and one end of the spring 16 is fixedly connected to the lower cutter fixing seat 1102.
[0027] When using the copper coil ultra-short lead cutting mold of this embodiment, the specific functions of each component are as follows: the left mold assembly 1 is installed on the left main shaft of the equipment via the left mold fixing seat 2; the cutting platform 33 is installed in the cutting groove 32, and the cutting platform 33 is used to block the cutting fixture 8; the cutting groove 32 and the cutting fixture 8 are precisely matched to ensure the accuracy and stability of the cutting.

Simultaneously, the wound coil detaches from the winding mold core 18 and enters the next working cycle. Due to the precise cooperation of the cutter fixture 8, the winding mold core 18, and the cutter platform 33, precise coil cutting can be achieved, ensuring that the lead wire length is qualified. Furthermore, by changing the winding mold core 18 and the corresponding cutter platform 33, coil processing of various specifications can be achieved, facilitating rapid product type adjustments and adapting to market demands.
