Title
(ES) MOLDE DE INYECCION DE PLATICOS CON EXTRACCION DEL AIRE INTERIOR Y PROCEDIMIENTO DE EXTRACCION DEL AIRE LLEVADO A CABO CON DICHO MOLDE.
Abstract
(EN) The invention relates to a plastic injection mould (1) which allows extracting the air from inside it during the injection process, and an extraction method, wherein said mould (1) basically comprises closing means, one or more injection cavities (2) provided with at least one injection nozzle for introducing the hot material in a liquid state and at least one ejector device formed by a housing (3) for an ejector pin (4) responsible for extracting the part already moulded, wherein an air duct (6) connected to a vacuum pump or a suction device (7) intercepts said housings (3) of the ejector pins (4) causing a suction of the air from inside the mould (1).
(ES) Molde de inyección de plásticos con extracción del aire interior y procedimiento de extracción del aire llevado a cabo con dicho molde. Molde (1) de inyección de plásticos que permite la extracción del aire de su interior durante el proceso de inyección y procedimiento para la extracción en donde dicho molde (1) básicamente comprende unos medios de cierre, una o más cavidades de inyección (2) provistas de al menos una boca de inyección para la introducción del material caliente en estado fluido y al menos un dispositivo expulsor formado por un alojamiento (3) para una varilla expulsora (4) encargada de la extracción de la pieza ya moldeada, en donde una conducción de aire (6) conectada a una bomba de vacío o un dispositivo de succión (7) intercepta dichos alojamientos (3) de las varillas expulsoras (4) provocando una succión del aire del interior del molde (1).
