Title (EN) DEVICE FOR THE PRODUCTION OF OPTICAL LENSES OF POLYMERIZABLE MATERIAL
(FR) DISPOSITIF DE PRODUCTION DE LENTILLES OPTIQUES EN MATERIAU POLYMERISABLE
Abstract:
(EN) Described is a mold for producing optical lenses from a polymerizable material and a method for such production. Said mold comprises a gasket (1) enclosing an aperture (2), which aperture (2) extends along an axis (14), and providing a contact surface (3) radially extending from said aperture (2), a first molding shell (4) abutting against said contact surface (3), a second molding shell (5) arranged within said aperture (2) at a distance from said first molding shell (4), means (6) for pressing said first molding shell against said contact surface, means (7) for radially pressing said gasket against said second molding shell, and a filling opening, thereby forming a molding cavity (8) that can be filled with molding material between said first (4) and said second (5) molding shell and said gasket (1).
(FR) L'invention concerne un moule pour la production de lentilles optiques à partir d'un matériau polymérisable et son procédé de production. Ledit moule est constitué d'une garniture d'étanchéité (1) entourant une ouverture (2), laquelle (2) s'étend le long d'un axe (14), et formant une surface de contact (3) s'étendant radialement depuis ladite ouverture (2), une première coque de moulage (4) venant buter contre ladite surface de contact (3), une deuxième coque de moulage (5) prévue dans ladite ouverture (2), à une certaine distance de la première coque de moulage (4), un moyen (6) pour comprimer ladite première coque de moulage contre ladite surface de contact, un moyen (7) pour comprimer radialement ladite garniture d'étanchéité contre ladite deuxième coque de moulage, et une ouverture de remplissage. Ainsi, une cavité de moulage (8) pouvant être remplie de matériau de moulage entre ladite première (4) et deuxième (5) coque de moulage et ladite garniture d'étanchéité, peut être formée.
