METHOD OF EJECTING MOLDED ARTICLE AND MOLDING APPARATUS

PROBLEM TO BE SOLVED: To provide a molding apparatus for releasing a molded article having undercut portions from a die. SOLUTION: The molding apparatus 1 for releasing the molded article 7 having undercut portions 7a, 7b from dies 2, 3, ... includes inclined cores 6a, 6b for forming the undercut portions 7a, 7b, pushing pins 11, 12 to be projected from the inclined cores 6a, 6b, sliding plates 10a, 10b provided on a lower die 3 where base end portions 11a, 12a of the pushing pins 11, 12 are configured to slide, and elastic members 13, 14 for pushing the pushing pins 11, 12 against the sliding plates 10a, 10b. When the inclined cores 6a, 6b are moved in a direction where the inclined cores 6a, 6b are separated from the molded article 7, the pushing pins 11, 12 are projected from the inclined cores 6a, 6b by the amount of the movement and push the molded article 7 so as to form a gap G between the molded article 7 and the inclined cores 6a, 6b.
