Abstract | A molding apparatus capable of improving the quality of a molded article is provided. A control section controls a blowing mechanism to expand and mold a metal pipe material by supplying gas into the metal pipe material held between an upper mold and a lower mold by a pipe holding mechanism. The control section controls a driving section to mold a flange portion by crushing a second molded portion of the expanded metal pipe material in a sub-cavity portion between the upper mold and the lower mold. In a molding apparatus, the control section changes movement speed of a slide during the molding of the flange portion by controlling a servomotor. Accordingly, it becomes possible to control an operation of pressing at an appropriate movement speed according to the shape or the like of the flange portion. Accordingly, it is possible to improve the quality of a molded article. |
