Rotary blow molding machine

A rotary blow molding machine comprising a rotor mounted on a horizontal driving shaft;

• mold stations mounted on the outer periphery of said rotor so as to be radially disposed and circumferentially equally spaced, said mold stations each carrying thereon a split mold unit capable of opening and closing in the direction of the width of the outer periphery surface of said rotor;
• flash blow-pipes rotatable with said mold stations, a tip end of each of said flash blow-pipes facing between said mold stations, said mold stations moving on a circular rotation track described by the center of each of said split mold units, said flash blow-pipes being adapted to guide and hold a parison extruded from a die head disposed adjacent to said track, said flash blow-pipes also being adapted to blow off a portion of the scrap parison, which is produced when closing and clamping said split mold units, to a position outside said circular rotation track;
• ejector means mounted in a wedged form between said split mold units within an area on said circular rotation track within which said split mold units are kept open;
• mold-release means on said split mold units for releasing a molded article from said split mold units and operable adjacent to said ejector means when said split mold units are open, said ejector means receiving a molded article released by said mold-release means from one mold half of said split mold unit in open state and discharging it to a position outside said circular rotation track.
