Abstract

PURPOSE: A device for forming socket part of pipe in which the surfaces of openings on the core mold for passing through divided molds which are fixed on a shaft so that they can freely expand and contract are covered with slidable plates, thus giving socket patrs with smooth surface and high mechanical strength.
CONSTITUTION: A plurality of divided molds 9 are connected with the top of arms 8 by a pivot so that they can freely go in and out through windows 4 on core mold 3. Thus, as the arm holder 7 on shaft 5 is moved to change the inclination of arms 8, divided molds 9 project through windows 4 toward groove 2 or move back. Firstly, the divided molds 9 are made to contract in the core mold 3, then the core mold 3 is inserted into the end part of softened plastic pipe P so that the divided molds 9 are made to oppose to groove mold 2. The divided molds are made to expand and project toward the groove 2. The expanded socket part s is formed by the outer mold 1 and the core mold 3 and simultaneously ring groove V is formed by groove mold 2 and divided molds 9. After cooling, the divided molds 9 is made to contact, the core mold 3 is taken out, then the pipe P along with socked part S are removed from the outer mold 1.
