INJECTION MOLDING DEVICE, INJECTION MOLDING METHOD AND HOUSING

摘要

There is provided an injection molding device in which the film cutoff and the injection molding can be conducted in one process without fine positional adjustment of the stopper and the shape of the edge surface of the member is not limited to the shape of the cutting blade. Resin is injected between a film (8) arranged on a cavity (1) as a metallic mold including a depression-shaped portion and a core (2) as a metallic mold including a projection-shaped portion to be inserted in the depression-shaped portion of the cavity (1), to thereby form a member; the cavity (1) includes a cutting blade (7) in an outer edge of the depression-shaped portion to cut off the film (8) arranged to project toward an outside plane of the depression-shaped portion; the core (2) includes an edge (3) in an outer edge of the projection-shaped portion to form an edge surface of the member; and when the core (2) is inserted in the cavity (1), the film (8) nipped by the cutting blade (7) and the edge (3) is cut off.
