| 20090022841 | MOLD ATTACHING/DETACHING APPARATUS AND MOLD ATTACHING/DETACHING METHOD - As cams provided on platen-side attachments move from a lock-releasing position to a locking position while the ball-supporting members of the platen-side attachments remain inserted in the ball-receiving members of mold-side attachments, locking balls sliding in inclined-locking grooves are moved outward in a direction at right angles to the direction in which the cams move, and are set in engaging-locking grooves and abut on the curved parts of the engaging-locking grooves. Therefore, the mold-side attachments are closely attached and fixed to the platen-side attachments. As the cams move from the locking position to the lock-releasing position, the pushing balls sliding in inclined-pushing grooves are moved outward in a direction at right angles to the direction in which the cams move, and abut on the curved parts of the engaging-pushing grooves. In this case, the mold-side attachments can project from the platen-side attachments. | 01-22-2009 |
