Injection molding tool for injection molding tool set for producing rolling bearing cage, has core, which limits multiple sections radially inwardly in axial direction adjacent to inner mold portion

摘要

The injection molding tool (100) has a side ring extending along a circumferential direction of a roller bearing cage and multiple webs, which are connected to the side rings, where two adjacent webs include a pocket for accommodating a rolling element. A core (340) limits multiple sections radially inwardly in an axial direction adjacent to an inner mold portion (250). An outer ring (230), the inner mold portion, an outer mold (290) and the core are detachably interconnected to a base mold portion (180). Independent claims are included for the following: (1) a method for manufacturing a rolling bearing cage; and (2) a method for modifying an injection molding tool for producing a rolling bearing cage.
