Abstract

Perfeccionamientos en las prensas para moldear materiales termoplásticos, y más particularmente en las prensas de cabezal rotativo para el moldeo de materiales termoplásticos por inyección, caracterizados porque la prensa comprende un par de portamoldes dispuestos preferiblemente de forma simétrica respecto de un árbol preferiblemente horizontal y susceptibles de rotación alrededor del mismo, estando conectado dicho árbol con unos primeros medios hidráulicos que proporcionan la presión de cierre del molde durante el período de inyección, estando adaptados dichos portamoldes para abrir en forma de ala e incluyendo unos segundos medios hidráulicos para mantener el molde cerrado durante el período de enfriamiento, proporcionándose además medios para realizar la rotación de dicho par de portamoldes.
