Abstract

"MéTODO DE MOLDAGEM POR INJEçãO". Um aparelho para a moldagem de uma lente ótica a partir de um material de resina termoplástica fundido, usando-se uma máquina de moldagem por injeção, e incluindo um meio para a formação de uma cavidade de molde definida por um par de inserções opostas espaçadas, conformadas e configuradas para a definição de faces opostas da referida lente ótica e tendo uma pluralidade de poços de extravasamento circundando a cavidade de molde; um meio para a injeção de um volume ótimo predeterminado de material de resina na referida cavidade de molde; um meio para o movimento de forma controlável de pelo menos uma inserção em relação à outra inserção, onde esse movimento relativo de inserção é direcionado por um cilindro de acionamento capaz de prover um curso de compressão variável, durante a moldagem, e é iniciado antes da conclusão da referida injeção; um meio para o controle da velocidade e/ou da força de compressão do referido cilindro de acionamento, de modo que a referida compressão seja conduzida em uma primeira velocidade selecionada relativamente alta, desse modo forçando a resina em excesso da referida cavidade para os referidos poços de extravasamento, após o que a força de compressão é variada para um nível secundário selecionado; um meio para a manutenção da força de compressão secundária selecionada na referida cavidade de molde; e um meio para ejeção da lente.
