摘要

A clamp includes (a) a first engager that engages with engagement parts formed at ends of the tiebars at the moving platen side after moving the moving platen in the fixed platen direction to close a die or mold, in the tiebar insertion holes of the moving platen, (b) a second engager that engages with engagement parts formed at ends of the tiebars at the fixed platen sides detachably at ends of clamping pistons using a detachable engager, (c) a pushing device that cooperates with the tiebars and pushes the moving platen after die or mold closing against the fixed platen in the tiebar insertion holes of the fixed platen, and (d) a tiebar inserting and extracting device coupled with ends of the tiebars at the fixed platen sides at a side of the fixed platen opposite to the die or mold mounting surface.
