Abstract:
1. A mold attaching/detaching apparatus for detachably attaching a stationary metal mold to a stationary platen and detachably attaching a movable metal mold to a movable platen of a molding machine, the apparatus comprising: a plurality of platen-side attachments secured to the stationary platen and the movable platen, and a plurality of mold-side attachments secured to the stationary metal mold and the movable metal mold, wherein each of the platen-side attachments includes: wherein each of the mold-side attachments includes: wherein when the cam moves from the lock-releasing position to the locking position while the ball-supporting member remains inserted in the ball-receiving member, the locking balls slide on respective inclined-locking grooves of the cam, and are moved outward in directions at right angles to the direction in which the cam moves, and are thereby set in respective engaging-locking grooves of the ball-receiving member, thereby fixing the mold-side attachment to the platen-side attachment, and wherein when the cam moves from the locking position to the lock-releasing position while the ball-supporting member remains inserted in the ball-receiving member, the pushing balls slide on respective inclined-pushing grooves of the cam, and are moved outward in directions at right angles to the direction in which the cam moves, and are thereby abut on respective engaging-pushing grooves of the ball-receiving member, thereby projecting the mold-side attachment from the platen-side attachment.
