Abstract

Elément de garniture (1) pour moule de pneumatique comprenant un corps délimitant une surface de moulage destinée à mouler au moins en partie la surface extérieure de la bande de roulement d’un pneumatique, ladite surface de moulage comportant une zone de dernier moulage une zone de premier démoulage (7) du pneumatique, caractérisé en ce que l’élément de garniture (1) comprend en outre un dispositif d’évent (20) situé dans la partie de l’élément de garniture destinée à mouler ladite zone de premier démoulage (7) et réalisé de manière à permettre le moulage du pneumatique lors de la fermeture du moule et, dès l’ouverture du moule, à assurer une arrivée d’air sur la surface de moulage de la zone de premier démoulage du pneumatique. Figure pour l’abrégé : Fig. 1Trim element (1) for a tire mold comprising a body delimiting a molding surface intended to mold at least in part the outer surface of the tread of a tire, said molding surface comprising a last molding zone a zone first demolding (7) of the tire, characterized in that the lining element (1) further comprises a vent device (20) located in the part of the lining element intended to mold said first demolding zone (7) and produced in such a way as to allow the molding of the tire when the mold is closed and, as soon as the mold is opened, to ensure an inlet of air on the molding surface of the first demoulding zone of the tire.
