Extrusion die of extrusion molding machine and Extruded pipe for manufacturing a spiral pipe, and method for manufacturing thereof

摘要

The present invention relates to an extrusion die for extruding an extruded tube for manufacturing a underground composite spiral synthetic resin tube, an extrusion tube for a spiral tube formed by the extrusion die for the extruder and a method of manufacturing the same.;Extrusion die for an extruder according to the present invention is fixed by inserting the core 130 to the cylindrical body 120 connected to the core cover 110, the core cover 110 and the extruder between the body 120 and the core 130 A conveying passage 140 through which the molding resin supplied from the first line 171 of the 170 is transferred is formed, and the center reinforcement extruder tube connected to the second line 172 of the extruder 170 at the center of the core 130. It is characterized in that 150 is arranged.;Extrusion die, core, molding resin, fiber material (long fiber / short fiber), extrusion pipe, core reinforcing material, extrusion molding pipe, piping part, protrusion reinforcement
