Abstract

PURPOSE: To mold easily a socket having a perpendicular surface in its innermost end and a smooth inner surface, in forming a socket of a plastic pipe, by a method wherein the front is expanded by the blow off air pressure and a socket forming die is forced into the inner end of the plastic pipe.
CONSTITUTION: A sleeve die 4 for forming a socket is provided slidably on a mandrel 1. When the die 4 is removed from an outer die 3, the end part P of a heated plastic pipe is inserted up to the middle part of the mandrel 1 and located so that an air outlet 2 of the mandrel 1 can be covered by the inner surface of the front part of the plastic pipe. Then, the front of the plastic pipe is expanded by blowoff air from the air outlet 2 and then, the die 4 for forming the socket is inserted into the outer die 3, therefore, the front part of the plastic pipe is expanded to form the desired socket.
