Description

Technical Field

[0001] The utility model belongs to the technical field of wire and cable processing, and particularly relates to a machine head front end adjustment device and a conducting wire. Background Art

[0002] In actual production, in order to ensure the safety of wires and cables, insulating the outer layer of conductors such as wires and cables is an important link in the production line. However, because the insulation layer is a thin layer, if the position of conductors such as wires and cables is not correct, the insulation layer will be off-core, with one side thick and the other side thin. The thin part will not meet the insulation requirements and will be broken down by current, causing leakage and personal safety accidents. In order to prevent the insulation layer from being off-core and evenly covering the conductor, the traditional extruder head is an inner mold fixed to the inner mold base with threads, and the mold core is installed on the inner mold with threads. This is achieved manually by moving the inner mold up, down, left and right. However, this adjustment method is extremely laborious and difficult to judge whether the adjustment is accurate. It is necessary to extrude the cable multiple times to observe whether the insulation layer is evenly wrapped. This is not only time-consuming and labor-intensive, but also wastes raw materials, increases production costs, and is extremely inconvenient. Moreover, when the conductor vibrates, it may also cause deviation from the center axis position, resulting in uneven thickness of the insulation material covering the conductor.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0036] like Figure 1-6As shown, the utility model provides a front-end adjustment device for a machine head, comprising a front mold 1 and a rear mold 2, wherein the front mold 1 and the rear mold 2 are detachably connected, a front mold core 11 is provided in the front mold 1, and a discharge port 111 is provided at the front end of the front mold core 11; the rear mold 2 comprises an outer mold 21, an inner mold 22 and a rear mold core 23, wherein the rear mold core 23 is arranged at the front end of the inner mold 22, and the rear mold core 23 and the inner mold 22 are arranged in the outer mold 21. The inner mold 22, the rear mold core 23, the outer mold 21 and the front mold core 11 together enclose an injection cavity 3, and the injection cavity 3 is connected to the second discharge port 111; the front end of the rear mold core 23 is provided with a first discharge port 231, and the rear mold 2 is provided with a feed channel 4 that passes through the inner mold 22 and the rear mold core 23 in sequence, and the feed channel 4 is connected to the first discharge port 231, and the injection cavity 3 is respectively connected to the second discharge port 111 and the first discharge port 231. It should be added that the front mold core 11 and the rear mold core 23 under the present invention are matching molds. In actual applications, the sizes of the discharge port 1 231 and the discharge port 2 111 have various specifications. The user can replace the front mold core 11 and the rear mold core 23 of different specifications according to production needs without changing the size of the front mold core 11 and the rear mold core 23. In an embodiment of the present invention, the front end of the rear mold core 23 is cylindrical and the end is gradually narrowed and flat. Therefore, the inner wall of the front mold core 11 is a flat structure corresponding to the end of the rear mold core 23. Correspondingly, the discharge port of the injection cavity 3 is a ring-shaped flat structure. In addition, the front mold core 11 and the rear mold core 23 described in the present invention can also be circular or other shapes that are compatible with the front mold 1 and the inner mold 22, which are more flexible to use and more practical.

[0037] Among them, an adjusting member 12 is provided between the front mold 1 and the front mold core 11, and the adjusting member 12 is rotatably connected to the front mold 1. The adjusting member 12 rotates to drive the front mold core 11 to rotate synchronously to achieve fine adjustment of the angle of the second discharge port 111, so that the second discharge port 111 matches the first discharge port 231. In the prior art, in order to make the second discharge port 111 match the first discharge port 231, the inner mold 22 is often moved in four directions of up, down, left and right by adjusting screws to drive the rear mold core 23 to move, so that the discharge port 1 231 of the rear mold core 23 matches the discharge port 2 111 of the front mold core 11, so as to achieve the purpose of non-eccentricity, while the front mold core 11 is fixed. However, this adjustment usually only requires fine-tuning, and the adjustment of the inner mold 22 is extremely laborious and difficult to judge whether it is adjusted accurately due to its own weight and internal structure, and multiple adjustments are required. Extruding the cable for the second time to observe whether the insulation layer is evenly wrapped is not only time-consuming and labor-intensive, but also wastes raw materials, increases production costs, and is extremely inconvenient. The difference between the present invention and the prior art is that fine-tuning is achieved by adjusting the front mold core 11, and the inner mold 22 and the rear mold core 23 remain stationary. It is only necessary to ensure the sealing of the connection between the inner mold 22 and the rear mold core 23. This not only avoids the disadvantages of the prior art adjustment method, but also effectively ensures that the molten fluid in the injection cavity 3 will not penetrate into the connection between the inner mold 22 and the rear mold core 23, thereby reducing the waste of raw materials and saving costs.

[0038] Specifically, if Figure 7 As shown, the front mold core 11 is arranged in the adjusting member 12 and is in close contact with the inner wall of the adjusting member 12, so when the adjusting member 12 is rotated, the front mold core 11 can be driven to move. In order to further make the connection between the front mold core 11 and the adjusting member 12 more stable and firm, a protrusion 112 is provided on the side wall of the front mold core 11, and the inner wall of the adjusting member 12 is provided with a groove 122 adapted to the protrusion 112, and the protrusion 112 is arranged in the groove 122.

[0039] Furthermore, if Figure 8 As shown, a through hole 13 is provided on the peripheral wall of the front mold 1, and an adjusting block 121 is provided on the peripheral wall of the adjusting member 12. The adjusting block 121 is slidably connected to the through hole 13, and there is a gap 131 in the horizontal direction when the through hole 13 is connected to the adjusting block 121. The adjusting block 121 moves horizontally in the gap 131. Since the adjustment of the discharge port 111 is a slight movement with a small range, a smaller gap 131 can be set. The range of rotation of the adjusting member 12 and the front mold 1 can be further limited, thereby ensuring the sealing of the connection between the adjusting member 12 and the front mold 1, so that the molten fluid in the injection cavity 3 will not penetrate from the connection between the adjusting member 12 and the front mold 1.

[0040] Furthermore, the peripheral wall of the front mold 1 is provided with an adjustment hole 14 and an adjustment hole 2 15, and the adjustment hole 14 and the adjustment hole 2 15 are respectively provided on both sides of the through hole 13, and one end of the adjustment hole 14 and the adjustment hole 2 15 are respectively connected to the inner wall of the through hole 13; the adjustment hole 14 and the adjustment hole 2 15 are respectively provided with a locking piece 141 and a locking piece 2 151, and the locking piece 141 and the locking piece 2 151 are respectively threadedly connected to the adjustment hole 14 and the adjustment hole 2 15, and the setting of the locking piece 141 and the locking piece 2 151 is to fix the position of the adjustment block 121.

[0041] When the front mold core 11 needs to be adjusted toward the adjustment hole 14, first loosen the locking piece 141 and the locking piece 2 151 outward so that the adjustment block 121 can rotate, thereby driving the adjustment piece 12 and the front mold core 11 to rotate, and then screw the locking piece 2 151 toward the locking piece 141 and press against the adjustment block 121, so that the adjustment block 121 is slightly moved toward the locking piece 141 to a suitable position, and then tighten the locking piece 141 toward the locking piece 2 151 and press against the adjustment block 121, so that the adjustment block 121 is fixed under the action of the relative directions of the locking piece 141 and the locking piece 2 151, thereby achieving fine-tuning of the front mold core 11.

[0042] When the front mold core 11 needs to be adjusted toward the second adjustment hole 15 , the operating principle is the same as above. This adjustment method is simple to operate, more labor-saving, and more practical.

[0043] like Figure 9 As shown, this is another embodiment of the present invention for fine-tuning the front mold core 11. The module 1 16 may not be provided with the adjustment hole 14 or the adjustment hole 2 15. The module 1 16 and the module 2 17 are used to press the adjustment block 121 up and down, so that the friction force of the adjustment block 121 abutting against the modules 1 16 and 17 up and down is sufficient to fix the adjustment block 121 and prevent it from shifting during operation. When it is necessary to fine-tune the front mold core 11 in the adjustment member 12, a hard column can be used to pry the adjustment block 121 at the gap 131 using the lever principle to move it and drive the front mold core 11 to rotate until it matches the discharge port 1 231 of the rear mold core 23.

[0044] like Figure 10As shown, this is another embodiment 2 of the present invention for fine-tuning the front mold core 11. In the embodiment 1, the adjustment of the adjustment block 121 is performed by adjusting the gap 131 in the through hole 13. In the second embodiment, the adjustment block 121 is performed outside the through hole 13 by extending the length of the adjustment block 121 so that it extends out of the outer wall of the front mold 1. When adjusting, it can be manually adjusted by directly grasping the adjustment block 121 with your hand and applying force to move it within the gap 131 of the through hole 13, or the adjustment block 121 can be clamped by a tool such as a wrench and moved within the gap 131, making movement more labor-saving and convenient.

[0045] Furthermore, if Figure 11 As shown, in order to facilitate the replacement of the front mold core 11, the front mold 1 also includes module one 16 and module two 17. The module one 16 and the module two 17 are detachably connected and fixed by bolts. The adjustment hole one 14 and the adjustment hole two 15 are both provided on the module one 16. When replacing, the bolts are unscrewed upwards, and the module one 16 can be moved upward to be separated from the module two 17. At this time, the front mold core 11 can be directly moved upward for replacement, and replacement is simple and convenient.

[0046] Furthermore, if Figure 12-13 As shown, the inner walls of the module 16 and the module 2 17 jointly form an annular groove 171 adapted to the adjusting member 12, and the adjusting member 12 is rotatably connected in the annular groove 171. The setting of the annular groove 171 can further support and fix the adjusting member 12, so that the adjusting member 12 is more firmly connected to the front mold 1; it should be supplemented that the injection cavity 3 formed by the inner mold 22, the rear mold core 23, the outer mold 21, the front mold 1 and the front mold core 11 is an annular conical structure, so that the molten fluid in the injection cavity 3 flows more smoothly, so the annular groove 171 is set to abut against the adjusting member 12, so that the adjusting member 12 can be connected to the inner wall of the front mold 1 to form a smoother arc surface, thereby increasing the flow speed of the molten fluid in the injection cavity 3 and making the molten fluid more fully squeeze out of the discharge port 2 111, thereby improving the use of the molten material, avoiding waste and reducing production costs.

[0047] Furthermore, if Figure 13As shown, since the front mold 1 and the rear mold 2 are detachably connected, a connecting piece 212 is provided at the front end of the outer mold 21 for connecting the front mold 1 and the rear mold 2. The inner wall of the connecting piece 212 and the top of the outer mold 21 jointly form a limiting groove 213. The lower end of the module 2 17 of the front mold 1 is provided with a boss 172 adapted to the limiting groove 213. The boss 172 is engaged with the limiting groove 213 to further strengthen the module 2 17. In order to improve the stability, a screw hole 2121 is further provided on the peripheral wall of the connecting member 212, one end of the screw hole 2121 is communicated with the limiting groove 213, and a locking member 3 2122 is further provided in the screw hole 2121, one end of the locking member 3 2122 passes through the screw hole 2121 and abuts against the peripheral wall of the boss 172, the locking member 3 2122 is threadedly connected to the screw hole 2121, and the locking member 3 2122 is used to fix the connecting member 212.

[0048] Furthermore, if Figure 14-15 As shown, the inner mold 22 has a peripheral wall provided with a drainage groove 221 connected to the injection cavity 3, and the outer mold 21 has a side wall provided with an inlet 211, and the inlet 211 is connected to the drainage groove 221. The material of the insulating layer wrapped around the wire produced by the present invention enters from the inlet 211, is melted into a liquid state through the drainage groove 221 after high temperature, and flows into the injection cavity 3 through the drainage groove 221, and is discharged from the discharge port 2 111. After cooling treatment, it is automatically wrapped on the wire coming out from the discharge port 1 231 and passing through the discharge port 2 111 to form an insulating layer.

[0049] like Figure 16 As shown, the utility model also provides a conductive wire, including an insulating glue 5 and a wire body 6, the wire body 6 is located in the feed channel 4 and passes through the inner mold 22, the rear mold core 23, the discharge port 1 231 in sequence and extends into the injection cavity 3, after the insulating glue 5 is hot-melted in the injection cavity 3 and wraps the wire body 6, the insulating glue 5 and the wire body 6 are discharged together from the discharge port 2 111, the shape of the wire body 6 is consistent with the shape of the discharge port 1 231 of the rear mold core 23, the shape of the wire body 6 can be flat or round, and different wire bodies 6 can be wrapped by replacing different front mold cores 11 and the rear mold cores 23 to form an insulating layer.

[0050] The following is a detailed description of the working principle of the utility model:

[0051] When the front mold core 11 and the rear mold core 23 are off-center, the adjustment method is to loosen the locking piece 141 and the locking piece 2 151 on the front mold 1 so that the adjustment block 121 can move. Since the adjustment block 121 is fixedly connected to the adjustment piece 12 and the front mold core 11 is located in the adjustment piece 12, the movement of the adjustment block 121 can drive the adjustment piece 12 and the front mold core 11 to move. If the adjustment block 121 needs to move toward the locking piece 141, first screw the locking piece 2 151 so that the adjustment block 121 can move. One end of the locking member 2 151 presses against the adjusting block 121 and moves toward the locking member 1 141 within the range of the gap 131. When it moves to a suitable position, the locking member 141 is tightened so that the adjusting block 121 is fixed under the action of the forces in the relative directions of the locking member 141 and the locking member 2 151, thereby achieving fine-tuning of the front mold core 11 so that the front mold core 11 and the rear mold core 23 are on the same axis and the discharge port position is adapted; if the adjusting block 121 needs to move toward the locking member 2 151, the operating principle is the same as above, but in the opposite direction.

[0052] The innovation of this utility model is:

[0053] The utility model is provided with an adjusting part to realize fine adjustment of the front mold core, so that the front mold core and the rear mold core remain coaxial and the position of the discharge port is adapted, which makes the operation simpler and more labor-saving. In addition, this adjustment method also avoids moving the rear mold core, improves the sealing performance of the connection between the rear mold core and the inner mold, effectively prevents the molten fluid from penetrating from the connection, reduces the waste of raw materials, and saves costs.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.

[0055] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
