Improvements in the molding of hollow bodies with crossed ends, characterized essentially by the fact of establishing in the mold in two pieces suitable for molding, a main core that corresponds to the natural axis of the piece and two secondary nodes, one for each arm of the crosshead, with the particularity that both secondary nodes normally impact against the flanks of the main, gathering the set of half-mold and core on the adapter plates of the injection machine, proceeding then to perform the injection by the contact plane between the half-molds, waiting for its solidification, after which it proceeds in phases, namely, opening of the machine, together with the half molds, separation of the secondary nodes, leaving the piece molded on the main core and finally ejection of this piece by any known means.
