Abstract

Un inyector para moldeo por inyección, que comprende: un cilindro plastificante (1), un colector (2), una boquilla de inyección (3) que tiene un ducto de descarga (30) en comunicación con tal ducto de alimentación (20) del colector, y una aguja (4) que se mueve axialmente en el ducto de descarga (30) para cerrar un orificio de salida (31) del ducto de descarga; proporcionándose un espacio entre la aguja (4) y el ducto de descarga (30). El inyector comprende medios de reducción de volumen (5) colocados en el ducto de descarga y adecuados para reducir el volumen del espacio entre la aguja y el ducto de descarga, los medios de reducción de volumen (5) sobresalen radialmente de un cuerpo de la boquilla de inyección (3) y/o de la aguja (4); los medios de reducción de volumen se separan de la aguja (4) o de las paredes internas del ducto de descarga (30).
