Process for die-casting a cage for roller bearings and associated apparatus

摘要

In a process for diecasting a cage (63) for roller bearings, with at least one pocket (46), open on one side or both sides for the roller body or bodies, slides (49, 64) are inserted into a casting mould and, on finish-casting the cage (63), in the pocket (46) are moulded onto at least one sidewall (50) with wall sections (60, 61) partially enclosing the roller bodies. So that the cage (63) can be made of a relatively rigid material, a cross-slide (49) with at least one end surface (53) which is moulded onto the inner and outer wall sections (60, 61), and one or two longitudinal slides (64) per pocket (46), are first inserted into the casting mould so that the longitudinal slide(s) (64) closely contact(s) the relevant end surface (53) of the cross-slide (49) between the two wall sections (60,61). A die-casting material is then filled into the casting mould. Finally, each cross-slide (49) is removed from the mould through the pocket (46) and each longitudinal slide (64) is removed through a longitudinal opening (66) of the cage (63) without an undercut. <IMAGE>
