置。 In front of the movable platen, which is moved by the mold clamping device and clamps the mold between the fixed platen fixed to the machine body, a safety door covering the mold part is movable in the direction of movement of the movable platen. In an injection molding machine installed in The machine body side has a locking pawl that locks onto the fixed teeth of the safety bar to prevent the mold clamping movement of the movable platen, and a locking pawl that is attached to the movable platen when the movable platen moves to open the mold. A stopper is provided with a rotating part that is rotated by the part to remove the locking pawl from the fixed tooth,
The safety bar is rotatably supported on a pivot within the plane of movement of the safety bar, and the safety door and the safety bar are provided with a stopper that rotates at the final stage of the safety door's closing movement to maintain the safety door in the closed state. Rotating means for retracting the locking pawl of the stopper from the locking position of the fixed tooth and freeing the locking rotation of the stopper that locks the locking pawl to the fixed tooth when the safety door is moved from the closed state to the open state. A safety device for an injection molding machine characterized by the addition of a safety device.
