Because the pressure of the materials of the molten pipe blank is released after extrusion, the molten materials cannot flow back into the cable guide pipe no matter the molten materials are pulled or not pulled.
A shunting shuttle 5 for reinforcing and protecting a cable guide pipe is fixedly arranged on the inner wall of the neck ring mold 1. In comparison with fig. 1, the cable conduit 7 is divided into a front section and a rear section, the front section of the cable conduit is inserted into the die wall of the mouth die 1, the rear section of the cable conduit passes through the interior of the diffluent shuttle 5, and the outlet of the cable conduit 7 passes through the diffluent shuttle 5 and slightly extends out of the extrusion end surface of the mouth die 1; wherein, one side surface of the shunt shuttle 5 far away from the inner wall of the mouth mold 1 is a plane, and the distance between the plane and the outer surface of the core mold 2 is smaller than or equal to the distance between the outlet of the cable conduit 7 and the outer surface of the core mold 2. That is, comparing fig. 1, the bottom of the shuttle is lower than or equal to the bottom of the cable conduit, which can reduce the impact of the material flow on the cable conduit and prevent the conduit from hitting the core mold to play a protective role when adjusting the uniformity of the wall thickness of the pipe.
