Process equipment for manufacturing aluminum alloy cable insulator and sheath

The invention relates to process equipment for manufacturing an aluminum alloy cable insulator and a sheath. The process equipment comprises an inner mold, a middle mold and an outer mold which are joggled in sequence, wherein the outer mold is provided with a sheath shunt, a pressing mold cover is arranged at the tail end of the outer mold, a first annular passage for injecting an insulating material is formed between the outer wall of the inner mold and the inner wall of the middle mold, a second annular passage for injecting a sheath material is formed between the outer wall of the middle mold and the inner wall of the outer mold, the sheath shunt is provided with an injection hole communicated with the second annular passage, and a conductor enters from the inner cavity of the inner mold, is matched with the insulating material to form an insulating layer when advancing to the inner cavity of the middle mold and is matched with the sheath material to form a sheath layer when advancing to the inner cavity of the outer mold. According to the technical solution, the conductor is subjected to extrusion when the insulating layer is formed and tube extrusion when the sheath layer is formed, thus realizing single extrusion of the high-temperature sheath material and the low-temperature insulating material; moreover, the insulator and the sheath have smooth surfaces and good concentricity, and the process equipment can realize high-speed continuous production.
