Problems solved by technology
This installation method is difficult to ensure that the central axis between the mold core and the mold sleeve is aligned and coincident, and it is also impossible to ensure that the above-mentioned central axis is on the horizontal line. During production, the adjustment bolts on the upper, lower, left, and right sides of the machine head must be adjusted to achieve the deviation of the sheath. Core degree, that is, the uniformity of thickness; at the same time, it is difficult to ensure the uniformity and stability of the pressure of plastic extrusion, so that the apparent quality of sheath extrusion is also difficult to guarantee

The invention provides an adjustment-free cable extrusion molding device, a mounting method thereof and a method for processing cable sheaths. The adjustment-free cable extrusion molding device comprises a head, an extrusion mold and a gland plate. The head comprises a runner and an annular supply channel vertically symmetric about the central axis of the head, and the annular supply channel is provided with supply ports; the extrusion mold is provided with a feeding channel and a molding hole, and the feeding channel is vertically symmetric about the central axis of the extrusion mold and is provided with feeding inlets; and the gland plate and the extrusion mold are provided with positioning holes, positioning pins are arranged in the positioning holes, the gland plate is fixedly connected with the extrusion mold by the positioning pins, and is further fixedly connected onto the head by connectors, the extrusion mold is embedded in the head, so that the supply ports are aligned with the feeding inlets, and the runner, the feeding channel, the annular supply channel and the molding hole form an extrusion molding channel. The device can be installed without adjustment, processing efficiency is improved, loss is reduced, and the quality of the processed cable sheaths further can be improved.
Description
technical field [0001] The invention belongs to the field of production and processing of flat sheaths for elevator accompanying cables, and in particular relates to an adjustment-free extrusion device for flat cables, an installation method thereof and a processing method for the cable sheaths. Background technique [0002] Due to the shape of flat elevator cables, the sheath must be processed by extrusion. The traditional processing method is: [0003] After the plastic comes out of the machine head, it is extruded on the cable core through the flow channel of the core seat along the surface of the core, and is formed by the mold sleeve. The installation of the mold is that the mold core and the mold core seat are fixed through threaded connection, and the mold sleeve is fixed on the machine head with four bolts on the top, bottom, left, and right sides and the gland plate, such as Image 6 shown. This installation method is difficult to ensure that the central axis betw...
