Abstract

Inyector de gas para el moldeo de piezas huecas de materia plástica, que comprende un tubo (1) conectado con una fuente de gas bajo presión y destinado a desembocar, a través de su extremidad, en la huella de un molde inyección de materia plástica para asegurar el hinchamiento de esta materia plástica y la realización de una pieza hueca, caracterizado porque el tubo (1) forma en esta extremidad (1{sub,1 ) el asiento de una chapaleta de obturación (4), prologándose esta chapaleta hasta el interior del tubo por medio de un vástago (5), dispuesto bajo la acción de un resorte (6), que asegura el cierre de esta chapaleta, estando dispuesto este vástago igualmente bajo la acción de un medio motor dotado con un medio de accionamiento para asegurar la apertura de la chapaleta en contra de la acción del resorte.
