Description

TECHNICAL FIELD

[0001] The present application relates to cable extrusion equipment, in particular to a special-shaped cable installation-free mold. BACKGROUND

[0002] In the existing wire and cable production and manufacturing, the outer sheath is generally formed by an extruder head. The main body of the extruder head is fixed with a core, and the outer side has a heating system to keep the plastic molten during the extrusion process, and form a ring-shaped plastic flow under the core distribution. The plastic flow passes through the mold, and the plastic is wrapped on the outer surface of the cable core through the constraint of the mold extrusion port and the subsequent cooling system to produce a wire and cable with an outer sheath. This processing method is very suitable for the extrusion molding of circular cables, but when the inner and outer molds are offset, the inner and outer molds and the core need to be adjusted to the same axis from the top, bottom, left and right four directions by adjusting the screws to achieve the extrusion molding of the wire and cable.

[0003] In the existing power and information transmission control system, multifunctional composite cables are needed. For example, the special-shaped cable for motor stator temperature measurement is composed of multiple functional unit cables. When using a traditional extruder head to extrude and form the outer sheath of the special-shaped cable for motor stator temperature measurement, large and high-power equipment is needed to complete the process, which increases energy consumption. At the same time, the thick circular structure needs a large amount of plastic to fill, which causes serious material waste and occupies a lot of space during installation, resulting in the large size of the electrical control equipment and increasing the cost. Therefore, in order to solve the above problems, it is necessary to arrange multiple functional unit cables in parallel, and it is necessary to change the circular cable to a flat one.

[0004] In the patent No. CN111674006A, an installation-free extrusion mold and installation method for a special-shaped cable for motor stator temperature measurement are proposed. This patent can complete the coaxiality of the inner and outer molds before installation by using an external positioner, and then complete the installation of the mold while maintaining the coaxiality, making the installation and disassembly of the flat cable extrusion mold convenient and fast. However, this patent can only adapt to the installation requirements of different width flat cable extrusion molds, and is not suitable for extrusion molds with different heights. In addition, manual alignment of the center axis of the outer mold is required during the installation of the positioner, which increases the operation difficulty of the installation personnel. SUMMARY

[0005] Therefore, the present application is made in view of the above problems, and the purpose of the present application is to adapt to different sizes of molds without manual alignment of the center axis of the outer mold by first fixing the position of the vertical positioner, then positioning the vertical height between the outer mold and the inner mold, and finally positioning the horizontal position of the outer mold and the inner mold, and automatically aligning the horizontal positioner to the center axis of the outer mold during horizontal positioning. The present application achieves the above-mentioned purposes through the following technical solutions:

[0006] A special-shaped cable installation mold without adjustment, comprising an outer mold, an inner mold, a vertical positioner, and a horizontal positioner, the inner mold is arranged in the inner mold; the vertical positioner and the horizontal positioner are located on the opposite side of the inner mold die mouth to fix the inner mold and the inner mold; the vertical positioner and the horizontal positioner are slidably connected; the vertical positioner is internally provided with an adjusting plate, the adjusting plate is inserted into the flat outer groove at the end of the outer mold and the inner groove at the end of the inner mold on the upper and lower sides for upward and downward support and fixation; the horizontal positioner is internally provided with an adjusting rod; the adjusting rod is inserted into the outer groove and the inner groove on the left and right sides for lateral support and fixation.

[0007] The present application has the following advantages:

[0008] 1. The present application can fix the relative position of the vertical positioner and the outer mold first, and then operate the vertical positioner and the horizontal positioner to correct the coaxiality of the inner mold and the outer mold, which can satisfy the coaxial adjustment of different sizes of inner molds and outer molds while reducing the risk of falling of the positioner during movement of the mold.

[0009] 2. The present application can automatically adjust the horizontal position of the horizontal positioner by the alignment spring inside the horizontal positioner to make the horizontal positioner in the center position of the inner mold and the outer mold, which increases the accuracy of the coaxiality of the inner mold and the outer mold while reducing the operation difficulty of the installation personnel.

[0070] The third knob 460 is coaxially fixedly arranged at the left side of the expansion part 461.

[0071] Working principle:

[0072] When the coaxial correction of the inner mold and the outer mold is needed: first, the vertical positioner 300 is attached to the corresponding side surface of the outer mold 100 away from the horizontal positioner 400, so that the vertical abutting plate 350 is located inside the outer abutting groove 110, the vertical adjusting plate 340 is located inside the inner abutting groove 220, the horizontal abutting piece 441 is located inside the outer abutting groove 110, and the horizontal adjusting piece 431 is located inside the inner abutting groove 220. Then, the first knob 301 is twisted to control the rotation of the second screw rod 330, thereby driving the two vertical abutting plates 350 to move away from the first mounting plate 310 until the two vertical abutting plates 350 are abutted with the upper and lower ends of the outer abutting groove 110 to fix the position of the vertical positioner 300. Then, the second knob 302 is twisted to control the rotation of the first screw rod 320, thereby driving the two vertical adjusting plates 340 to move away from the first mounting plate 310 until the rolling parts 343 at the front ends of the two vertical adjusting plates 340 are abutted with the upper and lower ends of the inner abutting groove 220 to limit the vertical height of the inner mold 200. Then, the third knob 460 is twisted to control the rotation of the third screw rod 420, thereby driving the horizontal adjusting plate 430 to move away from the second mounting plate 410 and pushing the horizontal abutting plate 440 to move through the alignment spring 450. When the horizontal abutting piece 441 on the horizontal abutting plate 440 contacts the arcuate positions on both sides of the outer abutting groove 110, the third knob 460 is continuously twisted, which makes the telescopic part 421 move horizontally relative to the telescopic part 461 and makes the horizontal positioner 400 move along the sliding groove 303 to the position coaxial with the outer mold 100. When the horizontal abutting pieces 441 at both ends of the horizontal positioner 400 contact the arcuate positions on both sides of the outer abutting groove 110, the alignment spring 450 is compressed. At this time, the horizontal positioner 400 is in the position coaxial with the outer mold 100. The third knob 460 is continuously twisted until the horizontal adjusting pieces 431 at both ends of the horizontal positioner 400 contact the arcuate positions on both sides of the inner abutting groove 220, and the horizontal position of the inner mold 200 is adjusted, so that the inner mold 200 moves horizontally along the rolling part 343 until the outer mold 100 and the inner mold 200 are in the coaxial position.

[0073] When the outer mold 100 and the inner mold 200 are needed to be removed: the third knob 460, the second knob 302 and the first knob 301 are untwisted in sequence to remove the vertical positioner 300 and the horizontal positioner 400.
