Each frame that constitutes the frame structure has a shape that can be combined together. One of frames provided on the fixed mold or the moveable mold is fixed thereto in a die clamping direction or a direction perpendicular thereto. The frame is fixed to the fixed mold of the die, leaving a predetermined gap in the direction perpendicular to that for fixing the frame structure to the die. The pressurizing mechanism that applies a pressing force in the direction other than for fixing the frame structure to the die. The hydraulic control mechanism is employed as the pressurizing mechanism.
