Description

Technical Field

[0001] The utility model relates to the technical field of cable production, in particular to a cable color strip extrusion die. Background Art

[0002] Cable color strip extrusion dies are widely used in the wire and cable industry, especially in situations where different cable functions need to be identified or where aesthetics are required, such as home appliances, automobiles, aerospace, etc. It is a special mold for producing cables. The working principle is to put the cable that needs to be extruded with color strips into the cable extrusion groove, and then use pressure or other driving methods to move the cable in the mold. At the same time, the molten color material is extruded through the color strip extrusion groove and adheres to the outer surface of the cable to form a color strip.

[0003] The extrusion die currently used has a complex structure. Due to different orders, the color and color stripes of the cables vary greatly, so the die needs to be frequently disassembled to clear the internal wire wrapping material. Due to its complex structure and many parts, the joints are fixed by screws, which not only affects the efficiency of disassembly and installation, but frequent disassembly can also easily lead to wire slippage, affecting the service life. In addition, different cable color stripes have different positions, and multiple different molds are required to achieve production. For this reason, we proposed a cable color strip extrusion die to solve the above problems. Utility Model Content

[0004] The present application provides a cable color strip extrusion die, which solves the problem that the cable color strip extrusion die is inconvenient to disassemble and easy to damage.

[0013] It can be seen from the above technical scheme that the present application provides a cable color strip extrusion die, which is installed on the wire insulation layer coating equipment. When it is used specifically, the wire passes through the cable groove and the outlet, and the molten insulating material is injected into the insulating material feed tube during the movement of the cable. When the insulating material fills the entire filling cavity, it comes out from the outlet at the same time as the wire to complete the cable coating. When the color of the color strip and its position are installed, the color strip feed tube is installed on the corresponding color strip positioning plate, and the remaining color strip positioning plates are installed with blind covers. During the process of wire outlet, color strips are formed on the outside of the cable. When it is necessary to replace cables of different models, the disassembly sleeve can be removed, and the filling cavity can be emptied before injecting new material. When only the color strip is replaced, only the color strip feed tube needs to be removed and replaced with the color strip feed tube that provides other color strips. When the specifications of the cable change, if the specification difference is not very large, the end cover can be replaced to produce cables of other specifications.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. By disassembling the sleeve, when replacing insulating materials of different specifications, only the sleeve can be disassembled to achieve the purpose of cleaning the filling cavity, and disassembly and assembly are convenient and quick;

[0017] 3. Through the setting of the color strip positioning plate, a variety of color strip entry methods can be set according to the color strip conditions of the cable. It is also convenient to replace different color strip pipes according to needs. When the color strip positioning plate has slippage and other phenomena, it can be replaced to increase the overall service life of the equipment.

[0018] To sum up, the insulating material of the present application first enters the filling cavity, and then the tightening and discharging work is completed in the disassembly sleeve. The material extrusion is uniform and stable, the position of the color strip is stable, and the structure of the present application is reasonably matched, which is convenient for disassembly and installation. Each vulnerable position can be replaced at low cost, thereby increasing the service life of the present application and reducing the cost of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0024] See also Figure 1-2 A cable color strip extrusion die comprises a jacket 1, which is a cylinder with screw holes at both ends. During specific installation, the jacket 1 is installed on the cable production equipment. The specific installation structure can refer to the prior art. One end of the jacket 1 is detachably connected with a disassembly sleeve 4. Specifically, the jacket 1 and the disassembly sleeve 4 are connected by a flange. The flange connection can make the connection highly sealed and can withstand higher pressure. After the disassembly sleeve 4 is removed, the inside of the jacket 1 can be cleaned, thereby improving the cleaning efficiency of the mold. The inner cavity of the disassembly sleeve 4 is set in a cone shape. Before discharging, the insulating material first fills the outer sleeve 1, and then enters the disassembly sleeve 4. Under the action of the conical cavity, it gradually converges to the center. At this time, the running line of the material can be improved. During the discharging process, the material can be evenly discharged and wrapped at the circumference of the cable. Specifically, the end of the disassembly sleeve 4 is detachably connected with an installation end cover 7, and the installation end cover 7 is provided with an outlet. The wires and the insulating material come out of the outlet at the same time, which is used to limit the discharging and stabilize the size of the cable so that the material is evenly wrapped on the cable. Different installation end covers 7 can be replaced according to the size of the cable, and this place is a vulnerable point of the mold. When there is a problem with the discharging of the installation end cover 7, a new installation end cover 7 can be replaced.

[0025] In the present practicality, a sealing plate 3 is detachably installed at the other end of the jacket 1. The sealing plate 3 is connected to the jacket 1 through a flange. A core mold 9 is fixed on the sealing plate 3. The sealing plate 3 and the core mold 9 are integrated into one. When the sealing plate 3 is removed, the core mold 9 can be removed together to improve the disassembly efficiency. A cable groove 8 is provided on the core mold 9 for passing the wire. The sealing plate 3, the core mold 9, the jacket 1, the disassembly sleeve 4 and the installation end cover 7 together form a filling cavity. The filling cavity is a thinner annular cavity. Under the action of the disassembly sleeve 4, the insulating material can be evenly wrapped on the wire to form a cable of a certain specification.

[0026] In the present invention, since the specifications of the color stripes of each type of cable are different, there are single-color stripes, double-color stripes or multi-color stripes. Therefore, a plurality of color stripe positioning plates 5 are arranged at equal intervals on the disassembly sleeve 4, and the color stripe positioning plates 5 are fixed to the disassembly sleeve 4 by screws. When the screw holes on the color stripe positioning plates 5 are thread-slipped, new color stripe positioning plates 5 can be replaced to improve the service life of the equipment. In the specific design, the number of color stripe positioning plates 5 is 2-4, which can meet the production of cables without color stripes, single-color stripes, double-color stripes, three-color stripes and four-color stripes, and there is no need to replace the mold. Specifically, the color stripe positioning plates 5 are arranged at equal intervals. The position plate 5 is installed with a color stripe feed pipe 10 or a blind cover 11, and the color stripe feed pipe 10 or the blind cover 11 is connected to the disassembly sleeve 4 through a flange. When a single color stripe is needed, one position is reserved to install the color stripe feed pipe 10, and the color stripe feed pipes 10 at other positions are blocked by the blind cover 11. When producing multi-color stripe cables, the color stripe feed pipe 10 and the blind cover 11 can be installed according to the angle. An insulating material feed pipe 2 is provided on the outer jacket 1 for injecting insulating material into the filling cavity. The outer jacket 1 can effectively fill the filling cavity and form a uniform insulating shell on the wire.

[0027] In some embodiments, a discharge head 6 is provided on the mounting end cover 7, and the wire outlet is located on the discharge head 6, which can reduce the thickness of the mounting end cover 7, and the discharge head 6 can also be replaced with a wear-resistant material to increase the service life of the mounting end cover 7.

[0028] In some embodiments, one end of the mold core 9 located in the disassembly sleeve 4 matches the inner cavity of the disassembly sleeve 4, so that the thickness of the filling cavity is uniform at each position. During the diameter change process, it is beneficial to uniformly apply force at each position, thereby extruding a uniform insulating coating.

[0029] It can be seen from the above technical scheme that the present application is installed on the wire insulation layer coating equipment. When it is used specifically, the wire passes through the cable groove 8 and the outlet. During the movement of the cable, molten insulating material is injected into the insulating material feed tube 2. When the insulating material fills the entire filling cavity, it comes out from the outlet at the same time as the wire to complete the cable coating. When the color of the color strip and its position are installed, the color strip feed tube 10 is installed on the corresponding color strip positioning plate 5, and the remaining color strip positioning plates 5 are installed with blind covers 5. During the process of outlet, color strips are formed on the outside of the cable. When it is necessary to replace cables of different models, the disassembly sleeve 4 can be removed, and the filling cavity can be emptied before injecting new material. When only the color strip is replaced, only the color strip feed tube 10 needs to be removed and replaced with the color strip feed tube 10 that provides other color strips. When the specifications of the cable change, if the specification difference is not very large, the end cover 7 can be replaced to produce cables of other specifications.
