Mold and process for manufacturing toothed sprockets for locking winding rollers of safety belts

Abstract

A mold for manufacturing toothed sprockets for locking winding rollers of safety belts, comprising a main cavity (4) to be filled with a molten metal alloy so as to define at least one disc-shaped body (102) of a toothed sprocket (100) having a toothing (101) on a peripheral surface thereof, and a secondary cavity (6) designed to define a tailpiece (105) jutting out of the toothed disc-shaped body (102) and brought into fluid communication with the main cavity (4). The main cavity (4) comprises a deflecting element (7) extending within the cavity (4) itself for deviating the metal alloy towards the secondary cavity (6).
