[Claims for Utility Model Registration] A molding material that has a gate part consisting of a direct gate or a pin gate, and the molding material containing an oriented material injected from the gate part comes into contact with the mold surface facing the gate part and then flows into the cavity. In the mold configured as above, a shielding member provided locally around the gate portion and movable in a direction protruding into the cavity and a direction recessing into the mold surface, and a drive device for driving the shielding member. and the shielding member protrudes into the cavity to change the flow of the molding material to control the orientation direction of the oriented material, and after the molding material fills most of the cavity. An injection molding mold characterized in that the entire cavity is filled with the molding material by immersing the shielding member into the mold surface.
