Abstract

Una unidad para actuar la varilla de un elemento de cierre en un molde para el moldeo por inyección de materiales plásticos, comprendiendo la unidad un elemento (21) de pistón deslizable en un elemento (20) de cilindro y conectable a una varilla (16) de cierre deslizable en un conducto (14) de inyección, entre una posición extendida en la que bloquea un orificio (15) de inyección, y una posición de inyección en la que se encuentra retraída en el conducto de inyección, que se caracteriza porque el elemento (21) de pistón posee un asiento (46, 47) de encaje, para alojar una porción (16a) extrema de cabeza de la varilla (16), estando el asiento de encaje configurado de tal manera que permite que el elemento (21) de pistón sea trasladado transversalmente en relación con la dirección axial de movimiento de la varilla (16) para liberar el elemento de pistón de la varilla.
