Patent attributes
A die clamping system enabling reduction of the size of a tie bar withdrawing mechanism, that is, a die clamping system provided with a fixed die plate, a moveable die plate, tie bars withdrawable from the fixed die plate, moveable parts engaging with the tie bars, withdrawal cylinders moving the moveable parts provided in the moveable die plate in a withdrawing direction, and a hook system engaging the moveable parts and the tie bars. When a second coupled part and a second coupling part are coupled, a drive mechanism moves said moveable die plate to a die opening direction and afterwards releases the coupling of the second coupled part and the second coupling part. When a coupling is formed by the hook system, the withdrawal cylinders move the moveable parts to a withdrawing direction.
