Injection molding tool for molding linear bearing cage has projections on each tool half which form ball or roller holding noses in molded cage

摘要

For the production of a single part, multi-row cage or a crossed roll cage each tool half (5,6) has projections (7,8) which when the tool is closed extend into the molding cavity (9) to form holding noses in the ball sockets of the molded cage. The holding noses lie within the cage base. An Independent claim is made for an anti-friction bearing cage for a linear bearing produced by the claimed tool. Preferred Features: In a similar molding tool for a cage with rollers instead of balls the projections (7,8) form holding noses for the rollers and contact faces (14) between them in the tool closure position are at an angle greater than zero to the closure direction (R).
