And the mold clamping device in the blow molding machine, blow molding machine equipped with the mold clamping device

摘要

The present invention is generated easily and ensure the desired mold clamping force, the structure was simplified to provide a clamping device in a blow molding machine. A pair of mold plate 18A. 18B are moved in the direction to mutually approach from the fully open position of the split mold, where it approaches a predetermined size, and negotiations a pair of claws 70A of negotiations pawl mechanism 70 into the annular groove 50A. After this, it activates the hydraulic cylinder unit 22, the move to the clamping direction of the cylinder 22A by the hydraulic force on the piston rod 22C, one of the type plate 18A and the other type plate 18B of the hydraulic cylinder unit 22 is mounted moves in the direction, split molds between a contact, together generate the desired clamping force, and receiving the reaction force claws mechanism 70 and the movable frame 60, also performed locking action of the mold. .BACKGROUND
