摘要： The clamping device has tie bars which are connected to a fixed platen and have engaged parts at a movable platen side, clamping cylinders which are provided on movable platens, half nut devices which are connected to pistons of the clamping cylinders and can mesh with the engaged parts, and stopper devices which restrict the movement of the half nut devices. Each stopper device has at least a driving unit and a stopper part which is driven in a mold opening and closing direction relative to the movable platen by driving of the driving unit and can engage with the half nut device from the fixed platen side. No winding transmission mechanism is interposed between the driving unit and the stopper part.
