  • Patent number: 6129883
    Abstract: The present invention relates to an improved injection molding machine and process. The injection molding machine includes a first mold half with at least one mold cavity or mold core and a rotatable turret means rotatable on an axis for rotating a pair of mating mold halves into alignment with the first mold half. Each mating mold half includes at least one mold core or mold cavity matable with the first mold half for forming a mold for forming at least one molded article. The turret block is movable so that a first one of the mating mold halves can be brought into contact with the first mold half. The machine also includes an injection system for injecting molten material into the mold to form the molded article(s). After the injection cycle is completed, the turret block with the molded article(s) thereon is moved away from the first mold half and is rotated by 180 degrees to align a second one of the mating mold halves with the first mold half and to bring the molded article(s) to an ejection position.

  • Patent number: 6113834
    Abstract: The present invention relates to a device for cooling molded parts and for transporting the molded parts from a receiving position to a holding/ejecting position. The device of the present invention has particular utility with an index molding machine having a rotary turret block with at least two movable mold halves thereon. The cooling device includes a cooling station assembly having a plurality of blowing tubes for applying a cooling fluid to external surfaces of molded parts, a take-off plate having a plurality of holders for receiving cooled molded parts and a connecting plate connecting the take-off plate and the cooling station assembly. The connecting plate is connected to the take-off plate by a pivotable connection and is connected to the cooling station assembly by a rigid connection. The connecting plate is movable along an axis substantially parallel to one of the faces upon which the molded parts to be cooled and removed are positioned.
