Abstract
The invention provides an extrusion forming die capable of producing two optical cables simultaneously. The extrusion forming die comprises an inner die body and an outer die body. A double-conical-head body is arranged at one end of the inner die body, and a concave part matched with the double-conical-head body of the inner die body is arranged on the tail portion of the outer die body. The inner diameter of the concave part is larger than the outer diameter of the double-conical-head body. After the double-conical-head body of the inner die body is inserted into the concave part of the outer die body, a flow pass allowing an optical cable outer sheath material to flow is formed between the double-conical-head body of the inner die body and the concave part of the outer die body. Two die openings of the double-conical-head body of the inner die body are provided with a first optical fiber outlet and a second optical fiber outlet correspondingly. Die openings of the outer die body comprise the first die opening and the second die opening. The first optical fiber outlet penetrates into the concave part of the outer die body and is located inside the first die opening, and the second optical fiber outlet penetrates into the concave part of the outer die body and is located inside the second die opening. According to the technical scheme, one production line can produce two optical cables at the same time, so that fixed asset input is reduced and cost is also reduced.
