Abstract
Process and apparatus for producing hollow bodies by injection molding, of any desired shape and having at least one comparatively large opening, whose method comprises the steps of arranging a continuous and elastic sheath provided with a number within the molding cavity. of openings equal to those of the finished piece, said sheath having an external surface equal to the internal surface of the piece to be emptied, and an internal surface suitable for receiving the components of a composite core; the introduction through the openings of the mold and the sheath of the core components into said sheath and the coupling of them therein; the fixation in its position of the coupled nucleus and of the enclosing sheath; sealing the mold openings by suitable means; the injection of the mouldable mass into the mold cavity, between the sheathed core and the surface of the mold cavity; the removal, after said mass has hardened, of the closures of the openings of the mold and the extraction of the components of the core of the sheath; and the extraction of the now empty sheath of the hardened cast part.
