EXTRUDING MOLD JOINT METHOD FOR ELECTRIC POWER CABLE

摘要

PURPOSE: To prevent the generation of burning due to the storing of a resin in a resin discharging part in an extruding mold joint method in which a foreign material detecting part and a foreign material discharging part are provided on the way of a communicating tube for connecting an extruder to a metal mold. CONSTITUTION: Overflow parts 47A, 47B for a resin are provided in a foreign material discharging part 37, and the filling of a resin into a metal mold 15 is performed while a resin is made to overflow from the overflow parts 47A, 47B. In order to eliminate the storing of a resin, the joint extrusion of a resin after the resin is filled into the metal mold is performed by making the resin overflow from the overflow parts. That is for the purpose of increasing a resin pressure.
