[Problem] To provide a molding device and a method for molding a thin plate-shaped substrate, with which it is possible to mold a thin plate-shaped substrate without residual distortion. [Solution] A lower die 10 (first die) and an upper die 20 (second die) are disposed so as to be capable of moving towards and away from each other. Protruding portions 20a are disposed on the upper die so as to protrude towards the lower die, and are provided with leading edges for forming stretched portions 200a stretched by localized pressing of a pre-molded article 200, and side edges for inducing deflection of sections that are continuous with the stretched portions, and forming bent portions 200b in spaces 10s formed in relation to the lower die. Tensioning portions 30 tension and stretch the bent portions. A controller 40 controls the operation of the lower die or the upper die, and the tensioning portions. The bent portions are tensioned and stretched by the tensioning portions while the stretched portions of the pre-molded article are still pressed by the lower die and the protruding portions of the upper die, imparting the shape of the protruding portions to the pre-molded article along the side edges of the protruding portions. The prescribed irregular shape of the pre-molded article is an irregular shape such that bent portions will be formed. |
