INJECTION STRETCHING BLOW MOLDING MACHINE

摘要

The injection mold clamping mechanism of an injection stretching blowing device which comprises a pair of mold clamping shafts that pass through a lower base and an upper base, are erected on the opposite sides of an injection molding operation unit and have their top ends joined by a top base, a plurality of hydraulic mold clamping means that are mounted to the underside of the lower base and joined to the lower ends of the clamping shafts positioned in a bed for respective mold clamping shafts, a mold clamping base that has in the middle of the bottom surface thereof a mold clamping block having a core mold mounted downward direction, has its opposite ends inserted into and supported on the mold clamping shafts, and is provided between the upper base and the top base so as to be movable vertically, a pair of air-operated mold opening/closing cylinders that join at the opposite sides the upper base with the mold clamping base and move the mold clamping base vertically with respect to the upper base, a mold clamping rod joined with the upper surface center of the mold clamping base through the opening in the center of the top base, and a pair of clamping members that are provided on the opposite sides of the opening in the top surface of the top base so as to be able to advance/retract, are fitted to the mold clamping rod by means of an air-operated clamp cylinder and join the mold clamping base and the mold clamping shafts.
