MOULD AND METHOD FOR THE MANUFACTURE OF A BRAKING BAND OF COMPOSITE MATERIAL WITH VENTILATION DUCTS AND HOLES IN THE FIRCTION SURFACES

摘要

A mould for moulding braking bands of composite material, with ventilation ducts, comprises a first half-mould (4) having a first impression surface (6) and a second half-mould (5) having a second impression surface (7). The half-moulds are movable towards each other and the two impression surfaces, together with suitable containment means, define a moulding cavity which has the shape of the braking band. The impression surfaces are intended to shape the friction surfaces of the braking band and the first half-mould comprises pin members (12), extensible and retractable, for forming the ventilation ducts with openings which open into the friction surfaces.
