Abstract

APARATO PARA MOLDEAR UNA VARIEDAD DE ARTICULOS DE DIFERENTES MASAS Y FORMAS EN EL CUAL SE INYECTA UNA PARTE DE MATERIAL A UNA PRESION CONSTANTE A TRAVES DE UNA VALVULA TEMPORIZADA (D) A UN DEPOSITO DE FUNDICION DEL MATERIAL A UNA TEMPERATURA Y UNA PRESION PREDETERMINADAS. LOS ARTICULOS SE MOLDEAN POR COMPRESION A UNAS PRESIONES PREDETERMINADAS ACORDES CON SU MASA Y SU FORMA. LA PRESION VARIABLE DE COMPRESION SE SUMINISTRA POR MEDIO DE UNOS ACTUADORES SIMILARES (42,66,74) LOS CUALES SE EXCITAN AL UNISONO. EN OTRA VERSION EXISTE UN UNICO ACTUADOR ACOPLADO A LA CAVIDAD DE MOLDEO POR MEDIO DE UNA MAQUINA QUE SUPONE UNA VENTAJA MECANICA. LOS ACTUADORES ESTAN FIJOS POR UN PIVOTE. EN PARTICULAR, EL APARATO SE UTILIZA PARA EL MOLDEO DE LENTES.
