Title (EN) SEALING RING FOR DIE CASTING PISTONS
(FR) BAGUE D'ÉTANCHÉITÉ POUR PISTONS MOULÉS EN MATRICE
Abstract:
(EN) The invention relates to a sealing ring (5) for die casting pistons, which has a circumferential groove (10) on its outer surface. The groove provides retention of the lubricant applied to the outer surface of the piston, so that it can be distributed evenly during the strokes of the piston within the cylindrical injection chamber.
(FR) L'invention concerne une bague d'étanchéité (5) destinée au moulage de pistons en matrice, comprenant une gorge périphérique (10) sur sa surface extérieure. La gorge permet de retenir un lubrifiant appliqué sur la surface extérieure du piston, de sorte qu'il peut être réparti uniformément pendant les courses du piston à l'intérieur de la chambre d'injection cylindrique.
