Abstract

Refinements in injection molding apparatus to produce hollow articles of thermoplastic materials, of the type comprising, a mold with a die penetrating a core to form a molding cavity, and positioning means for locating opposite faces of the bottom of the die and the male part therein, relative to one another, including male and female positioning elements, one carried by the male and the other by the die, which provide cooperative positioning surfaces, and means for moving an element positioner relative to the other during the course of the molding operation, characterized in that one of the positioning elements is formed as an injection nozzle through which the thermoplastic material is injected into the mold, and the means used to move one of the positioning elements are arranged to retain it, during the injection of most of the molding material, in a position operating or operating position, where the positioning surfaces are separated by a small gap practically less than the thickness of the wall of the article and, during the injection of the final part of the material, to retain it in a retracted position where the positioning surfaces are separated in a distance comparable to the wall thickness of the article to ensure that the wall thickness between them is perfect.
