A rubber splitting cable mold for high density and uniform extrusion

Abstract

The invention discloses a rubber splitting cable mold for highly dense and uniform extrusion. The structure includes a control panel, a cushion block, a device main body, and a rubber splitting extrusion mechanism. The control panel is fixed on the upper end of the front of the device body by screws. There are two pads and they are respectively welded on the lower surface of the main body of the device. The rubber material splitting extrusion mechanism is embedded in the upper end of the device main body. The present invention is provided with a rubber material splitting extrusion mechanism, and the rubber material splitting adjustment mechanism is connected with the upper end of the device body. The pressure measuring plate and the lower pressure measuring plate cooperate with each other to detect the glue pressure at the upper and lower ends of the cable, and control the feeding amount of the flow channel through the hole to adjust the glue pressure, so that the glue pressure at both ends is balanced and the rubber density after the preliminary molding is uniform. And the thickness is consistent, the rubber height chamber extrusion mechanism cooperates with the cooling water channel to uniformly extrude the initially formed rubber, increase the density of the rubber, discharge air bubbles, enhance the strength of the rubber, and make the performance of the produced cable more reliable.

Description

technical field [0001] The invention is an extruded cable mold, especially aimed at a rubber splitting cable mold which realizes highly dense and uniform extrusion. Background technique [0002] The cable is a vehicle used to transmit power and information. The cable is divided into a cable core and an external insulating rubber. The cable core is composed of one or more wires. The cable core needs to be covered with a layer of rubber after production. The rubber is usually used The cable mold is extruded, and the traditional cable mold will have some problems when it is used; affected by the gravity and the injection pressure of the rubber, the thickness of the rubber at the upper and lower ends of the cable is uneven or the density of the rubber at both ends is different. Bubbles, low rubber density, poor strength, cracks appear after being impacted by strong external force, poor insulation in humid environment.

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a rubber shunting cable mold that realizes highly dense and uniform extrusion, so as to solve the problem of uneven thickness of the rubber at the upper and lower ends of the cable or at both ends due to the influence of gravity and the injection pressure of the rubber material. There are differences in the density of the rubber. After the rubber is formed, there are air bubbles inside. The density of the rubber is small, the strength is poor, and cracks appear after being impacted by a strong external force. The insulation is poor in a humid environment.
