Date Sep. 3, 1998A mold-clamping device for a blow molding machine. The device includes a body and tie bars which move forwardly and backwardly while supported in a horizontal posture by the body. It also includes front and rear platens which are disposed on the front and rear end portions of the tie bars. A movable platen which is forwardly and backwardly movable is also disposed on the tie bars in such a manner as to face the front platen. Split mold halves are disposed on opposite sides of the front platen and the movable platen. The body portion is provided with a crank mechanism and a driving source so that the driving force transmits a driving force to a crank shaft of the crank mechanism. The rear platen and the movable platen are connected to a crank arm of the crank mechanism through connecting rods.
