[0001] The utility model relates to the technical field of extruder components, in particular to an adjustment-free cable extruder head. Background Art

[0002] At present, an extruder is needed for the production of cables. As the core component of the extruder, the extruder head directly determines the quality of the cable. When extruding insulating materials, the inner insulation layer is very thin and once the inner mold is eccentric, it is easy to cause the insulation layer to rupture. At the same time, mold eccentricity will also cause glue blockage.

[0003] In order to solve the above technical problems, a Chinese utility model patent with authorization announcement number CN211591225U discloses a double-layer extrusion device for locomotive cables, which includes a wire sleeve, a manifold, a core seat, a mold core, a mold sleeve, a mold sleeve seat, a rubber guide tube and an outer shell. By arranging the center lines of the mold sleeve, the mold core and the mold core seat in a straight line with the center line of the cable, the problem that the mold is not easy to be eccentric and the insulating inner layer is not easy to rupture can be solved.

[0004] The above technical solution has the following problems: the wire sleeve and the manifold (core seat) are connected to the outer shell (mold body) by bolts. This fixing method increases the difficulty of removing the wire sleeve and the manifold from the inside of the outer shell. Workers need to use tools to unscrew the bolts one by one before they can remove the wire sleeve and the manifold, so the efficiency is low. Utility Model Content

[0013] The unlocking component is used to drive the rotating plate to rotate, thereby driving the abutment head to open the stopper to release the limit of the blocking block.

[0014] As the preferred technical solution of the utility model, the mold body, the core seat, the mold core and the mold sleeve form a feed cavity connected to the feed port, and the central axes of the core seat, the mold core and the mold sleeve coincide with each other. The cable to be sealed with glue passes through the wire groove opened in the core seat and the core cavity opened in the mold core, and the sealed cable passes through the extrusion port opened in the mold sleeve.

[0015] As a preferred technical solution of the utility model, a protrusion is provided at the rear end of the mold core, and the protrusion is engaged with a recessed cavity opened at the front end of the mold core seat.

[0016] As a preferred technical solution of the utility model, the surface of the mold sleeve is provided with external threads, and the external threads cooperate with the internal thread grooves provided at the front end of the mold body.

[0036] The above technical solution enables the cable to be sealed to pass through the wire groove 4 of the core mold seat 3 and the core cavity 6 of the core mold 5, and the hot-melt insulating layer material is fed into the feed cavity 9 from the feed port 2. The insulating material wraps the cable to seal it. The sealed cable passes through the mold sleeve 10 and is extruded from the extrusion port 11.

[0037] Further, such as Figure 2 As shown, a protrusion 7 is provided at the rear end of the mold core 5, and the protrusion 7 is engaged with a recessed cavity 8 opened at the front end of the mold core seat 3;

[0040] By adopting the above technical solution, the mold sleeve 10 can be installed at the front end of the mold body 1. When disassembly is required, the mold sleeve 10 can be disassembled by rotating the external thread 12 on its surface to disengage the internal thread groove 13 at the front end of the mold body 1.

[0041] Further, such as Figure 1 and Figure 2 As shown, the mold body 1 includes two equally divided shells, and the non-adjustable cable extruder head also includes: a bolt 15, which penetrates a mounting hole 14 provided on the outside of one of the shells, and a threaded end of the bolt 15 cooperates with a threaded groove 16 provided on the inside of the other shell;

[0042] The above technical solution can be used to conveniently split the mold body 1 into two parts. The bolts 15 can be unscrewed from the mounting holes 14 using a tool, and the shell of the mold body 1 can be opened, making it convenient to maintain the shell.

[0043] like Figure 3 and Figure 5As shown, the non-adjustable cable extruder head also includes: a limit seat 301, which is arranged at the rear end of the core seat 3; a clamping block 17, which is arranged at the rear end of the mold body 1, and the clamping block 17 passes through the clamping slot 18 opened on one side of the limit seat 301; a stopper 19, which is arranged in the limit seat 301; an elastic member 20, which is used to push the stopper 19 to contact the clamping block 17 to limit the clamping block 17; specifically, the elastic member 20 is selected as a spring;

[0044] The above technical solution can be used to conveniently fix the core seat 3 to the rear end of the mold body 1. When the core seat 3 and the core 5 need to be installed, the protrusion 7 at the rear end of the core 5 is aligned with the recessed cavity 8 at the front end of the core seat 3 and then inserted into the recessed cavity 8 on the surface of the limit seat 301. The retaining block 17 at the rear end of the mold body 1 pushes the retaining block 19. When the retaining block 17 enters the maximum position of the retaining groove 18, the elastic member 20 drives the retaining block 19 to reset, and the retaining block 19 engages with the retaining block 17, thereby completing the installation of the core seat 3 and the core 5. Compared with the traditional installation method, no tools are required, which improves efficiency.

[0046] The above technical solution can be used to quickly disassemble the core seat 3 and the core 5. When the core seat 3 and the core 5 need to be disassembled, the handle 28 is held and rotated. The handle 28 drives the rotating shaft 26 to rotate, and the rotating shaft 26 drives the second bevel gear 27 to rotate. The second bevel gear 27 drives the first bevel gear 25 to rotate. The first bevel gear 25 drives the rotating plate 21 to rotate. The rotating plate 21 drives the contact head 22 to contact the stopper 19, so that the stopper 19 is out of contact with the clamping block 17. At this time, the clamping block 17 can be pulled out of the clamping groove 18, thereby separating the limit seat 301 from the mold body 1, thereby realizing the rapid disassembly of the core seat 3 and the core 5.

When the block 17 enters the maximum position of the slot 18, the elastic member 20 drives the block 19 to reset, and the block 19 is engaged with the block 17, thereby completing the installation of the core seat 3 and the core 5;

[0049] When it is necessary to disassemble the core seat 3 and the core 5, hold the handle 28 and turn it. The handle 28 drives the rotating shaft 26 to rotate, the rotating shaft 26 drives the second bevel gear 27 to rotate, the second bevel gear 27 drives the first bevel gear 25 to rotate, the first bevel gear 25 drives the rotating plate 21 to rotate, and the rotating plate 21 drives the abutment head 22 to abut against the stopper 19, so that the stopper 19 is out of contact with the clamping block 17. At this time, the clamping block 17 can be pulled out of the clamping groove 18, thereby separating the limit seat 301 from the mold body 1, and realizing the rapid disassembly of the core seat 3 and the core 5.
