Procedure for releasing a molded lens in a cavity between mold sections posterior and anterior

摘要

A release procedure of the peripheral regions of a cured lens (10) adhered to a concave demoldeado surface (26) of a mold section (22), the method comprising the steps of: a) providing a support member (30) having a longitudinal axis and a face (33d) presented above to support mold (22), face to abut a convex outer surface (290a) of mold configured presented above; b) locating the convex outer surface of the mold section on the support face; c) applying a longitudinally directed force to a flange (200) projecting from a skirt portion (24) of the mold section, with sufficient force to cause the concave surface of molded presented above mold deviates in the direction the application of force, thereby breaking the uniónadhesiva between the lens and the molding surface of the mold section at least around peripheral REGIONS lens; characterized in that the support face to the mold section is in a form of an annular surface rodeauna opening formed in the support member, such that when the surface convex outer (290a) dela mold section abuts the annular surface, a portion of the outer convex surface projects in laabertura, the sized and shaped opening so being the permaneceseparada outer concave surface of the surfaces defining the opening, starting the rupture of the adhesive bond between the bordeexterior lens (10) and the concave surface (26) forming the lens and continues in the direction of center Lalente.
