The outer walls of the bottom ends of the plurality of positioning plug plates 2012 are semicircular in vertical section. A docking slot that matches the outer wall of the positioning plug plate 2012 is provided at the junction of the die body 1 and the positioning plug plate 2012. The semicircular outer wall allows the docking insert ring 4 to be accurately inserted into the interior of the docking slot through the plurality of positioning plug plates 2012.

When the model of the die nozzle 3 needs to be replaced, the limit lock of the docking ring 4 can be released through the replacement mechanism. At the same time, the positioning plate 2012 is used to limit the die nozzle 3 under the obstruction of the inner wall of the die body 1, thereby preventing the die nozzle 3 from rotating during the unlocking process.

[0041] After that, the die nozzle 3 is pulled to move. At this time, the docking ring 4 slides along the inner wall of the die body 1 under the drive of the die nozzle 3, and through the mutual cooperation with the replacement mechanism, the die nozzle 3 can be conveniently disassembled. After that, the above operation is reversed to conveniently install and fix the new type of die nozzle 3. In this way, different types of die nozzles 3 can be replaced according to actual use needs, which is beneficial for producing different types of cable sheaths without having to replace the die body 1, thereby further reducing the production cost of the cable sheath and improving production efficiency.

[0042] In one embodiment, Figure 2-Figure 5 As shown, the replacement mechanism further includes: a positioning assembly provided on the die body 1, the positioning assembly being used for automatically engaging and positioning the butt-joint ring 4;

[0043] The positioning assembly includes: a plurality of positioning plugs 204 equidistantly arranged on the outside of the butt plug ring 4 in the circumferential direction, the plurality of positioning plugs 204 are all located inside the die body 1, and the plurality of positioning plugs 204 pass through the die body 1 to the inside of the butt plug ring 4;

[0044] The positioning block 204 is provided with a first limiting component, which is used to limit the sliding movement of the positioning block 204;

[0048] An extrusion assembly is provided at one end of the limiting push rod 206 away from the limiting baffle 205, and the extrusion assembly is used to squeeze and fix the limiting push rod 206. Through the hemispherical outer wall, the positioning plug 204 can be accurately inserted into the interior of the positioning slot through the limiting baffle 205 under the rebound push of the spring 2011, so that the docking ring 4 can be automatically engaged and positioned.

[0049] In one embodiment, Figure 2-Figure 5 As shown, the extrusion assembly includes: a limiting push block 207 fixedly connected to the end of the limiting push rod 206 away from the limiting baffle 205, a positioning pressure block 208 is provided above the limiting push block 207, the positioning pressure block 208 is connected to the die body 1 for sliding up and down, the outer wall of the bottom end of the positioning pressure block 208 is inclined, the upper surface of the limiting push block 207 and the inclined outer wall of the positioning pressure block 208 are in contact with each other, the limiting push block 207 is slidably connected to the positioning pressure block 208 and the die body 1, and the inclined outer wall allows the limiting push block 207 to slide along the inner wall of the die body 1, and the positioning pressure block 208 can be pushed to move by extrusion;

[0050] A second limiting assembly is provided on the positioning pressing block 208, and the second limiting assembly is used to limit the lifting and lowering of the positioning pressing block 208;

[0051] In one embodiment, Figure 2-Figure 5As shown, the second limiting assembly includes: two limiting sliders 209 symmetrically fixedly connected to the outer wall of the positioning pressure block 208, both of which penetrate into the interior of the die body 1, and a linear slide 201 for the limiting slider 209 to slide is provided at the junction of the die body 1 and the limiting slider 209. Through the mutual cooperation between the limiting slider 209 and the linear slide 201, the positioning pressure block 208 can slide within the interior of the die body 1.

[0052] A locking assembly is provided above the die body 1, and is used to squeeze and lock the positioning block 208;

[0053] In one embodiment, Figure 1-Figure 5 As shown, the locking assembly is a rotating pressure ring 202 provided on the upper surface of the die body 1, the rotating pressure ring 202 is sleeved on the outer wall of the die nozzle 3 and the limit retaining ring 203, the rotating pressure ring 202 is threadedly connected to the die nozzle 3, and the outer wall of the limit retaining ring 203 is truncated cone-shaped, and the rotating pressure ring 202 can quickly slide and sleeve the outer wall of the limit retaining ring 203 through the truncated cone-shaped outer wall;

[0054] The positioning pressing block 208 is provided with a rolling assembly, which is used to reduce the friction between the positioning pressing block 208 and the rotating pressing ring 202;

[0055] In one embodiment, Figure 3-Figure 5 As shown, the rolling component is a ball 2010 arranged on the top of the positioning pressing block 208 , the ball 2010 is slidably connected to the positioning pressing block 208 , and the ball 2010 contacts the lower surface of the rotating pressure ring 202 .

[0056] The above embodiment discloses a cable material production extruder die, wherein, when in use, the extruder can extrude the cable sheath through the die body 1 and the die nozzle 3. When the model of the die nozzle 3 needs to be replaced, the rotating pressure ring 202 is rotated to rise along the outer wall of the die nozzle 3, and the rotating pressure ring 202 is separated from the outer walls of the limit ring 203 and the ball 2010, thereby releasing the limit lock of the docking plug ring 4. During this process, the docking plug ring 4 limits the die nozzle 3 under the obstruction of the inner wall of the die body 1 by the positioning plug plate 2012, thereby preventing the die nozzle 3 from rotating synchronously with the rotation of the rotating pressure ring 202.

[0057] Then, the rotating pressure ring 202 is pulled to drive the die nozzle 3 to rise synchronously. At this time, the docking ring 4, driven by the die nozzle 3, drives the positioning plug plate 2012 to separate from the inner wall of the die body 1. At the same time, the positioning plug block 204 is squeezed by the docking ring 4 and pushes the limiting push rod 206 to slide along the inner wall of the die body 1 through the limiting baffle 205. At this time, the limiting baffle 205 is retracted by moving the extrusion spring 2011. At the same time, the limiting push block 207 is pushed by the limiting push rod 206 to squeeze the inclined outer wall of the positioning pressure block 208. At this time, the positioning pressure block 208 slides along the inner wall of the die body 1 under the squeezing and pushing of the limiting push block 207. At the same time, the limiting slider 209 slides along the inner wall of the linear slide groove 201 under the drive of the positioning pressure block 208, so that the die nozzle 3 can be easily disassembled;

[0058] When the docking ring 4 is separated from the outer wall of the positioning block 204 by movement, the spring 2011 pushes the limit baffle 205 by rebounding to make the positioning block 204 slide and reset. Then the above operation is reversed, and the new model of die nozzle 3 can be conveniently installed and fixed. In this way, different models of die nozzles 3 can be replaced according to actual usage requirements, which is beneficial when producing different models of cable sheaths without replacing the die body 1, thereby further reducing the production cost of the cable sheath and improving production efficiency.
