Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
An extruder head capable of maintaining the coaxiality of a cable cladding is shown in the combined figures 1 to 4 and comprises an outer die 2, a core die 1, an extrusion cavity 3, a glue through hole 4 and a wire through hole 11.
The outer die 2 comprises a connecting cylinder 21, end caps 22 and outer die end plates 23.
The connecting cylinder 21 is detachably connected with a mold body of an extruding machine. An external thread 211 connected with the extruder in a threaded manner is formed on the outer wall of the connecting cylinder 21, so that the outer die 2 can be connected with the extruder in a threaded manner.
The end cap 22 is integrally provided at one end of the connector barrel 21, and the outer diameter of the end cap 22 is larger than that of the connector barrel 21.
The core mold 1 is integrally connected with the inner part of the outer mold 2 and is coaxially arranged with the outer mold 2.
