ABSTRACT:
Arrangement for the die casting of a roller bearing cage having pockets for the rolling bodies includes an outer housing covering the die casting mold and having guide openings opening at the central planes of the respective pockets and main and auxiliary slides arranged side by side in each guide opening. The main and auxiliary slides have guiding surfaces at their inner ends directed at an angle to the central plane, the guiding surfaces being laterally opposite one another and supporting one another. Each auxiliary slide has a lateral bulge on the side thereof opposite the guiding surface of the guide opening for defining a lateral limit wall of the pocket with holding projections for the rolling bodies on the inner and outer edges. The arrangement in accordance with the invention requires few components, provides a compact construction, and is economically produceable. The main slides are each operable from the exterior of the apparatus, and have recesses with inner and outer shoulder surfaces. The respective auxiliary slides have holding lugs extending into the recesses of the respective main slide between the inner and outer shoulder surfaces thereof with play. The auxiliary slides further have support surfaces on the sides thereof opposite the holding lugs with an outer edge running along the boundary wall of the corresponding pocket and supported on the wall of the guide opening of the housing, the auxiliary slide being arranged to be tiltable in the guide opening about the boundary edge.
