を特徴とする型締装置における保護装置。 It has a movable plate position detection device, and opens and closes the mold in a plurality of sections from the mold opening stop position to the mold closing stop position of the movable plate at a predetermined movement speed of the movable plate set in advance for each of the plurality of sections. A mold clamping device of an injection molding machine that operates includes a speed calculation section that calculates a moving speed of the movable platen based on a position signal from the position detection device, and a speed calculation unit that stores in advance an allowable speed value of the movable platen for each of the plurality of sections. and a control unit that determines that the moving speed of the movable platen is abnormal if the moving speed value of the movable platen from the speed calculation unit exceeds the allowable speed value of the section. A protection device in a mold clamping device characterized by:
