Title: MOLDING DEVICE AND MOLDING METHOD
Abstract:
A molding device is provided with: a first cavity portion which is formed between a first mold and a second mold and which is for molding a pipe portion; a second cavity portion which communicates with the first cavity portion and which is for molding a flange portion; a flange adjustment member which can be advanced into the second cavity portion and withdrawn from the second cavity portion, and which adjusts the length of the flange portion in an intersecting direction that is a direction intersecting an axial direction of the pipe portion; and a control unit which controls gas supply from a gas supply unit, driving of a drive mechanism, and the advancing and withdrawing of the flange adjustment member. The control unit implements a first control for causing the flange adjustment member to advance into the second cavity portion, a second control for causing the gas supply unit to supply gas for preliminary molding of the flange portion of which the length has been adjusted by the flange adjustment member, and a third control for causing the flange adjustment member to be withdrawn from the second cavity portion, in sequence during the molding of a metal pipe.
