Description

Technical Field

[0001] This utility model relates to the field of cable processing equipment technology, and in particular to a self-aligning cable extruder head that is easy to assemble and disassemble. Background Technology

[0002] Currently, extruders are used in cable production. The extruder head, as the core component of the extruder, directly determines the quality of the cable. When extruding insulating materials, the inner insulation layer is very thin, and any eccentricity of the inner die can easily lead to the breakage of the insulation layer. At the same time, die eccentricity can also cause glue blockage. Currently, traditional cable extruder heads have the following problems: First, the components of traditional cable extruder heads mostly use welded or complex fixed structures, making disassembly and assembly difficult. When components such as the die core are worn or need to be changed in specifications, the disassembly and installation process is time-consuming and labor-intensive, greatly affecting production efficiency and increasing maintenance costs. Second, the die core position of traditional extruder heads is fixed, making it difficult to ensure the concentricity of the cable during the extrusion process, which easily leads to quality problems such as uneven cable wall thickness. Especially when producing high-precision cables, it is impossible to meet quality requirements. Therefore, it is necessary to design a self-aligning cable extruder head that is easy to disassemble and install to solve the above problems. Utility Model Content

[0003] The main purpose of this utility model is to provide a self-aligning cable extruder head that is easy to assemble and disassemble, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A self-aligning cable extruder head for easy assembly and disassembly includes a mold body. A feed inlet is provided on the upper part of the outer surface of the mold body. A mating interface is formed around the left end of the mold body. A first screw hole is formed on one side of the left end of the mold body. A left through slot is formed in the middle of the left end of the mold body. A second spiral groove is provided on the right side of the inner wall of the left through slot. A mold core seat is fixedly connected to the middle of the inner wall of the mold body. A mating assembly is inserted into the mold core seat. A right through slot is formed in the middle of the right end of the mold body. A first spiral groove is formed around the right end of the mold body. A discharge assembly is provided on the left end of the mold body.

[0006] Preferably, the docking assembly includes a mold core body, a first thread is provided on the right side of the outer surface of the mold core body, a docking shell is movably connected to the right side of the outer surface of the mold core body, a core cavity is provided inside the mold core body, a second thread is provided on the outer surface of the docking shell, a third through slot is opened in the middle of the right end of the docking shell, and the mold core body is located inside the mold core seat.

[0007] Preferably, the discharge assembly includes an extrusion disc, a second screw hole is opened on one side of the left end of the extrusion disc, docking blocks are fixedly connected to all four sides of the right end of the extrusion disc, a connecting groove is opened in the middle of the right end of the extrusion disc, a connecting sleeve block is movably engaged in the middle of the right end of the extrusion disc, a third thread is provided on the right side of the outer surface of the connecting sleeve block, an extrusion cavity is opened in the middle of the right end of the connecting sleeve block, a fixing bolt is threadedly connected to the second screw hole, and the extrusion disc is threadedly fixed to the left end of the mold body by the fixing bolt.

[0008] Preferably, the positional dimensions of the four mating blocks correspond one-to-one with the positional dimensions of the four mating interfaces, and all four mating blocks have a concave structure, and the positional dimensions of the fixing bolt are adapted to the positional dimensions of the first screw hole.

[0009] Preferably, the positional dimensions of the connecting sleeve block are adapted to the positional dimensions of the second spiral groove, and the positional dimensions of the connecting groove are adapted to the positional dimensions of the connecting sleeve block.

[0010] Preferably, the left side of the mold core body is located on the right side of the inner wall of the connecting sleeve block, and the mold core body has a hollow conical structure.

[0011] Preferably, the mating blocks are distributed in a ring at equal intervals along the right edge of the extrusion disc, and the concave opening of each mating block faces the direction of the mold body.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In this utility model, the modular design of threaded connection (first thread, second thread, third thread) and snap-fit ​​structure (butt block and butt interface) enables quick disassembly and assembly of various components of the extruder head. Compared with traditional welding or complex fixing methods, this structure significantly simplifies the process of mold core replacement, cleaning and maintenance, and reduces downtime and labor costs. For example, the extrusion disc is fixed to the screw hole of the mold body by fixing bolt, and the concave snap-fit ​​of the butt block and butt interface ensures accurate positioning. Disassembly can be completed without special tools, which is particularly suitable for the frequent mold change requirements in the production of multi-specification cables.

[0014] 2. In this utility model, the hollow conical structure of the die core body and the matching design of the connecting sleeve block allow the die core to be finely adjusted in the radial direction. Combined with the guiding effect of the spiral groove and the thread, the concentricity of the die core and the extrusion cavity can be corrected in real time. This self-aligning function effectively solves the problem of uneven cable wall thickness caused by traditional fixed die cores. It is especially suitable for the production of high-precision cables (such as thin-walled insulation layers or coaxial cables), ensuring that the concentricity error of the extruded cable is less than 0.05mm, and significantly improving the product qualification rate.
