INJECTION MOLDING APPARATUS AND INJECTION MOLDING METHOD

摘要

The invention relates to an injection molding apparatus and an injection molding method. The injection molding apparatus (10A) is provided with: a middle mold (20) which is disposed between a fixed mold (16) and a movable mold (22) and in which a through hole (52) that opens into both the fixed mold (16) and the movable mold (22) is formed; a first nozzle (36) for supplying the molten material into a first cavity (204a); a second nozzle (38) for supplying the molten material to a second cavity (204b); and a sealing member (68) capable of sliding on the wall surface configuring the through hole (52). The sealing member (68) is pushed to the side where the first mold (16) is positioned and is pressed against the second nozzle (38).
