Patent number: 7841059Abstract: 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.Type: GrantFiled: July 9, 2008Date of Patent: November 30, 2010Assignee: Star Seiki Co., Ltd.Inventor: Kouji Mizuno

Patent number: 7559265Abstract: Even if the coupling surface of an arm side attachment and a tool side attachment is directed in a direction other than the horizontal direction, the tool side attachment can be automatically separated and detached from the arm side attachment. When exchanging a tool, the worker does not have to forcibly pull out and detach a tool side attachment from an arm side attachment, a tool can be exchanged automatically, and the exchange work can be performed easily in a short period of time. When the cam member 17 is shifted from the unlocking position to the locking position, locking balls 13 which slide on locking inclined tapered surfaces 17a to be shifted to the outside along the radius direction are engaged with engaging inclined tapered surface 23a so as to mutually couple an arm side attachment 3 and a tool side attachment 5.Type: GrantFiled: August 24, 2007Date of Patent: July 14, 2009Assignee: Star Seiki Co., Ltd.Inventor: Kouji Mizuno
