Abstract

PURPOSE: To contrive so that an expanded socket of high precision may be formed with a simple core mold by providing a plurality of outer molds with elastic inner peripheral material which move mutually in a direction crossing a core mold axis at right angle on the external periphery of an expanded socket part.
CONSTITUTION: A plural number of outer molds 11 are arranged on the external periphery of a support part 7 and an expanded stepped part 10, and these outer molds move in a direction crossing the axial core of a core mold 4 at right angle with the assistance of drive means such as an actuating cylinder, etc. and the periphery of tube for insertion forming 1a is tightly fastened. Inside the inner forming part of the outer mold 11, an elastic material 12 made of heat-resistant synthetic rubber, etc. is provided. On the elastic material 12, a forming surface 12a which pressure-forms a nonexpandable part and a forming surface 12b which forms an inclined part 2c are premolded and pressure-formed. At the same time, under this condition, the tube for forming 1a is again pressed into an arrow direction under this state. As a result, a socket 2 is formed with the opposite surface of the expanded stepped part 10 the thickness thereof is being increased.
