Abstract

La présente invention concerne un moule d'injection en plusieurs parties (100) pour la fabrication d'une bague d'étanchéité (1) dans un espace creux de moule (2), avec une première et une deuxième partie extérieure (4 ; 6) pour former un corps de base d'étanchéité (8) et avec un éjecteur (10) en forme de fourreau conçu pour éjecter la bague d'étanchéité (1), l'éjecteur (10) comportant une surface avant (42) pour la formation d'une surface latérale (44) du corps de base d'étanchéité (8), et avec une partie intérieure disposée à l'intérieur de l'éjecteur (10) pour la formation d'un contour intérieur de la bague d'étanchéité (1) sous la forme de deux lèvres d'étanchéité (14 ; 16) de préférence placées selon un certain angle l'une par rapport à l'autre, la partie intérieure étant réalisée au moins en deux parties.The present invention relates to a multi-part injection mold (100) for the manufacture of a sealing ring (1) in a hollow mold space (2), with a first and a second external part (4; 6 ) to form a sealing base body (8) and with a sheath-shaped ejector (10) designed to eject the sealing ring (1), the ejector (10) having a front surface (42) for the formation of a lateral surface (44) of the sealing base body (8), and with an inner part disposed inside the ejector (10) for the formation of an inner contour of the ring d 'sealing (1) in the form of two sealing lips (14; 16) preferably placed at a certain angle to each other, the inner part being made at least in two parts.
