Abstract
1.Dispositivo de moldeo para la fabricación de piezas moldeadas con superficies asféricas a partir de material termoplástico, particularmente lentes de gafas, al cual está constituido por dos troqueles, determinando las superficies de los troqueles que quedan vueltas una hacia otra la forma de la pieza que ha de fabricarse, caracterizado porque la menos uno de los dos troqueles está provisto de una depresión de forma de cubeta, sobre la cual va asentada una placa de pieza moldeada de configuración asférica elásticamente deformable, que es deformada durante el proceso de fabricación por efecto de la presión del material termoplástico de una manera tan definida que se origina una superficie asférica predeterminable de la pieza moldeada. 2.Dispositivo según la reivindicación 1, caracterizado porque la deformación predeterminada por sus condiciones de borde y/ sujeción. 3.Dispositivo según las reivindicaciones 1 o 2, caracterizado porque la deformación predeterminable de las placas de pieza moldeada viene determinada por uno o varios troqueles auxiliares soportados elásticamente dentro de los otros troqueles. 4.Dispositivo según la reivindicación 3, caracterizado porque los troqueles auxiliares están unidos con un sistema hidráulico para generar presiones prefijables. 5.Dispositivo según las reivindicaciones 2, 3 o 4, caracterizado porque las condiciones de borde y/o de sujeción de las superficies limitadoras de las piezas moldeadas no son simétricas en rotación y/o los troqueles auxiliares elásticamente soportados están dispuestos de manera no simétrica en rotación. 6.Dispositivo según una o varias de las reivindicaciones 1 a 5, caracterizado porque una o ambas superficies limitadoras de piezas moldeadas son planas. 7.Dispositivo según una o varias de las reivindicaciones 1 a 6, caracterizado porque una superficie limitadora de pieza moldeada es de configuración tórica. 8.Dispositivo según la reivindicación 7, caracterizado porque la superficie de configuración tórica es rígida. 9.Dispositivo según una o varias de las reivindicaciones 1 a 8, caracterizado porque las superficies limitadoras de piezas moldeadas están dispuestas una con respecto a otra de tal manera que los planos tangenciales aplicados a los puntos centrales forman un ángulo entre sí 10.Dispositivo de moldeo, para la fabricación de piezas moldeadas con superficies asféricas a partir de material termoplástico.
