Abstract
This disclosure relates to a mold construction particularly adapted for the blow molding of hollow articles having configurated bottoms. The mold is split longitudinally of the article and includes first and second halves each having a separate end portion. The end portions are interconnected so that when the mold is open, both end portions are retained with one mold half with one end portion moving relative to its respective mold half both longitudinally and transversely for both moving transversely with a molded article and longitudinally away from the molded article so as to first completely release the molded article from one mold half, and the end portion of the other mold half being thereafter movable longitudinally with respect thereto to separate the other end portion from the molded article and thus permit the ejection of the molded article from the mold. The molds are arranged in end-to-end substantially touching relation wherein there is a minimum of waste material between adjacent molded articles.
