回転式ブロー成形機。 Below the extruder that extrudes the parison, a turntable on which a plurality of pairs of opening/closing molds for sandwiching and blow-molding the parison is mounted is rotatably disposed, and a turntable is placed on the turntable via a base plate. In a rotary blow molding machine equipped with a mold clamping device for opening and closing the pair of opening/closing molds, the mold clamping device is fixed to a pair of guides parallel to each other on the base plate via a support block. a shaft, a pair of movable plates that are slidably provided on the pair of guide shafts, and each of the above-mentioned molds is fixed to opposing surfaces, and one end of each of the movable plates is fixed to the back side of each of the above-mentioned molds. a pair of clamp rods that abut and separate the two clamp rods, and a pair of clamp rods that are swingably supported by a bracket installed at one end of the base plate via pivots located below the height of each of the guide shafts, and one of the clamp rods is attached to the upper end of the bracket. a swing lever whose other end is pivotally supported and whose lower end protrudes below the upper surface of the base plate; and a swing lever which is slidably supported below the base plate, and whose one end is a clamp rod of the one of the swing levers. A slide rod pivotally supported at a lower end separated by the same distance as the distance between the other end and the pivot shaft, a connecting plate connecting the slide rod and each other end of the other clamp rod, and a pair of actuators to reciprocate the connecting plate. The toggle mechanism is made to be movable, and closes the pair of opening/closing molds by the forward movement of the connecting plate, and opens the pair of opening/closing molds by the backward movement of the connecting plate and maintains the state thereof. A rotary blow molding machine characterized by:
