Rubber material flow-diving cable mold capable of realizing highly dense and uniform extrusion molding

Abstract

The invention discloses a rubber material flow-diving cable mold capable of realizing highly dense and uniform extrusion molding. The rubber material flow-diving cable mold structurally comprises a control panel, cushion blocks, a device main body and a rubber material flow-diving extrusion molding mechanism, the control panel is fixed at the upper end of the front surface of the device main bodythrough screws, the two cushion blocks are provided totally and welded on the lower surface of the device main body correspondingly, and the rubber material flow-dividing extrusion molding mechanism is embedded in the upper end of the interior of the device main body. According to the rubber material flow-diving cable mold, the rubber material flow-dividing extrusion molding mechanism is arranged,a rubber material flow-dividing adjusting mechanism cooperates with an upper pressure measuring plate and a lower pressure measuring plate to detect rubber pressure at the upper end and the lower endof a cable, moreover, the rubber pressure is adjusted by controlling the feeding amount of a flow channel through flow-diving material holes, so that the rubber pressure at the two ends is kept balanced, a preliminarily formed rubber sheet is uniform in density and consistent in thickness, a rubbers sheet highly denseness extruding mechanism and a cooling water channel cooperate with each other,so that the preliminarily formed rubber sheet is uniformly extruded, the density of the rubber sheet is improved, bubbles are discharged, the strength of the rubber sheet is enhanced, and the producedcable is more reliable in performance.

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.
