The silicon core pipe has the characteristics of good sealing performance, chemical corrosion resistance and low engineering cost, and is widely used for optical cable communication network systems. In the construction process, firstly, the silicon core pipe is laid, and then the optical cable or the cable is laid inside the silicon core pipe; therefore, the optical cable and the electric cable can be protected through the silicon core pipe. The problem that the pipeline laying line cannot be cleared after construction drawings are lost often occurs in the long-term use of the existing silicon core pipe. In order to solve the problem, a method of laying a tracing line in the wall of the silicon core pipe is adopted, so that people can find the laying line of the silicon core pipe through the tracing line after the silicon core pipe is laid. At present, in the production process of silicon core tubes with tracking wires, people often directly pass the tracking wires through the existing die to finish the wire laying work of the tracking wires. However, when the method is adopted, because the silicon core tube has the characteristic of softness and easy deformation in the molding process in the die, the tracking wire is easy to move relative to the unformed silicon core tube under the action of subsequent traction force, so that the tracking wire which is supposed to be positioned at the center of the silicon core tube wall is eccentric and is finally positioned close to the inner wall or even protrudes out of the inner wall. In order to solve the problem, for example, in a wire laying die disclosed in the production process of a silicon core tube with an information wire disclosed in the document with the document number of US20030094297a1, a mode of directly arranging a reinforcing rib inside the silicon core tube is adopted to avoid the problem of exposure on the inner wall of the silicon core tube, but the problem that a tracking wire is easy to be eccentric when the existing die is produced is not fundamentally solved.

When plastic melt enters the outer layer melt cavity 18 through the flow restriction round surface 27, the plastic melt can be guided to enter the outer layer melt cavity 18 along the outlet of the inner layer die 4 of the flow restriction round, so that the problem of mixing of the inner layer plastic melt in the inner layer melt cavity 25 and the outer layer plastic melt in the outer layer melt cavity 18 can be caused. When the inner plastic melt enters the outer melt cavity 18 through the flow-limiting circular surface 27, the inner plastic melt enters the outlet annular opening 30 along the flow-guiding conical surface 28 to form a silicon core tube, and then the silicon core tube is output.
The guide die cylinder 7 penetrates through the inner layer mouth die 4 and extends to the mouth die gland 12, and then a wire laying core die 8 is in threaded connection (see the attached figures 7 and 8 in the specification); the wire laying core mold 8 is in a cylindrical structure; an outlet pipe ring mouth 30 is formed between the wire laying core mould 8 and the mouth mould gland 12; a wire ring edge 31 is arranged on the wire coating core mould 8 at the inner side of the pipe ring opening 30 (see the description and the attached figure 8); a plurality of arc-shaped wire grooves 32 are uniformly distributed on the circumferential surface of the wire annular edge 31 (refer to the attached figure 9 in the specification).
