Claims

[Scope of utility model registration request]

The fixed mold and the movable mold of the mold for injection molding the heated molten metal are indented, and the movable mold is inflated to form a raised part, thereby reducing the thick part of the molded product. In addition to forming a molding space for forming into a deep drawn hat shape,
Continuing from this molding space, a movable mold is formed vertically,
The deep rib molding groove that forms deep ribs in the molded product is formed by a deep riff molding partial insert fitted into a movable mold and a movable mold opposing this deep rib molding partial insert. ,
The sleeve that guides the ejector turbine that extrudes the deep ribs of the molded product is fitted into the sleeve through hole provided between the partial insert and the movable mold, concentric with the groove for forming the upper rib. injection mold.
