Since the wire 6 to be processed can rotate in the storage cavity 11, the insulating material can evenly cover all parts of the wire; the forming port 4 is connected to the mold body 1 through the connecting bolt 5, which is convenient for adjustment or replacement when necessary. The size and shape of the forming port 4 can be adjusted according to the thickness of the insulation layer of the wire to be produced, thereby realizing the production of insulation layers of different thicknesses; the wire inlet pipe 31 reduces the direct contact and friction between the wire 6 to be processed and the mold body 1, thereby reducing the wear on the mold body 1; the connecting bolt 5 provides a convenient disassembly and installation method.

[0022] A feed pipe 21 is installed inside the feed port 2, and a feed sleeve 22 is fixed to the upper end of the feed pipe 21. The feed sleeve 22 mainly functions to achieve a tight connection between the feed pipe 21 and an external material supply device, ensuring that the insulating material can stably and continuously enter the feed pipe 21 and then enter the storage cavity 11 of the mold, and can also prevent material leakage at the connection.

[0023] A feed limit groove 12 is provided at the upper end of the mold body 1, and a feed sleeve 22 is installed in the feed limit groove 12 by connecting bolts 5. The feed limit groove 12 ensures that the feed sleeve 22 can be stably installed on the mold and will not move or deviate during the processing.

[0024] The inner section of the wire inlet port 3 and the wire inlet tube 31 is smaller than the outer section. A wire inlet sleeve 32 is provided on the outer side of the wire inlet tube 31. The main function of the wire inlet sleeve 32 is to fix the wire inlet tube 31. The inner section of the wire inlet tube 31 is smaller than the outer section. This design helps the wire 6 to be processed to rotate and advance more stably in the tube, reduce friction with the mold, and avoid wear.

[0025] A wire entry limiting groove 13 is provided on the rear side of the mold body 1, and a wire entry sleeve 32 is installed inside the wire entry limiting groove 13 through a connecting bolt 5. The wire entry limiting groove 13 ensures that the wire entry sleeve 32 can be accurately and stably installed on the mold without moving or offsetting during the processing.

[0026] The forming mouth 4 is installed on the front side of the mold body 1 through the connecting bolts 5. The forming mouth 4 has various sizes and can be replaced through the connecting bolts 5. When it is necessary to produce insulation layers of wires of different specifications, it is only necessary to remove the original forming mouth 4 and then install the forming mouth 4 of the corresponding size, which greatly improves the flexibility and efficiency of production.

[0027] As an embodiment of the utility model: when using the wire insulation layer extrusion die, first select a suitable molding port 4, and install it on the front side of the die body 1 through the connecting bolts 5. This design enables the die to flexibly adapt to the production requirements of wires of different specifications, thereby improving production efficiency and flexibility; connect the feed pipe 21 to the external material supply device through the feed sleeve 22 to ensure a tight connection and prevent material leakage; install the wire inlet pipe 31 at the wire inlet port 3 of the die body 1 through the wire inlet sleeve 32 to ensure that the wire inlet pipe 31 is stable and does not shake. The design that the inner side section of the wire inlet pipe 31 is smaller than the outer side section helps the wire 6 to be processed to rotate and advance more stably in the pipe, thereby reducing friction with the die;

[0028] The wire to be processed 6 is passed through the front end of the wire inlet pipe 31 and enters the storage chamber 11 through the wire inlet port 3. The external material supply device is started to make the insulating material flow into the storage chamber 11 from the feed port 2 and wrap around the wire to be processed 6. The wire to be processed 6 rotates in the storage chamber 11 to ensure that the insulating material is evenly covered on various parts of the wire. After being extruded through the forming port 4, a wire insulation layer of the required specification and thickness is formed; thereby completing the use of the wire insulation layer extrusion mold.
