Abstract

La presente invención se refiere a un ensamble de molde para producir una unidad integral de preforma de lente-copa de molde, adecuada para acabado subsecuente a una lente óptica, que comprende; una copa molde que tiene una cavidad definida en él para recibir monómeros de material de lente, sin curar, y una superficie soportadora de matriz, sobrepuesta a, y que circunscribe dicha cantidad, y adaptada para recibir sobre ella una matriz para coactuación con ella, para contener los monómeros dentro de la cavidad radial, situable sobre la superficie soportadora de matriz, mientras se curan los monómeros hasta acoplamiento adherente con la copa de molde, y removible de allí para proveer una unidad integral de preforma de lente-copa de molde.
