Abstract
L'invention concerne un dispositif pour mouler une lentille en une matière plastique liquide. Selon l'invention, il comprend un organe de moulage inférieur 15 définissant une première surface 19, et qui reçoit la matière plastique liquide; un organe supérieur de moulage 17 ayant une surface inférieure 36 définissant une seconde surface de lentille; un moyen de suspension pour suspendre l'organe supérieur au-dessus de l'organe inférieur afin de définir une cavité entre les deux surfaces, ce moyen de suspension pouvant maintenir l'organe supérieur parallèle à l'organe inférieur tout en lui permettant d'être attiré vers l'organe inférieur tandis que la matière plastique liquide durcit dans la cavité; le moyen de suspension comprend une bague d'espacement 20 disposée autour de l'organe inférieur et plusieurs languettes flexibles 32 s'étendant vers l'organe supérieur et qui reposent sur la bague 20. L'invention s'applique notamment à la fabrication de lentilles ophtalmiques.
