The technical difficulties such as selecting the parting surface and designing the structure of the molding part of injection mold were researched emphatically on the basis of the analysis of the structure of the angular contact ball bearing cage and the injection molding process. Thus a structure design scheme of the combined cavity and punch is put out which would be easy to manufacture and satisfy the precision requirement. A complete set of bearing cage injection mold,which would be simple and reliable,is finally proposed.
