Abstract

Dispositivo de bloqueo antirretorno (1) que para el control del flujo de masa fundida de plástico está dispuesto en el extremo de un husillo de plastificación e inyección (2), para controlar el flujo de masa fundida de plástico de la zona de rosca helicoidal (3) del husillo de plastificación e inyección (2) a la zona de la cámara anterior (4) del husillo de un cilindro de extrusión (5) en el que se encuentra el husillo de plastificación e inyección (2), presentando el dispositivo de bloqueo antirretorno (1) un cuerpo de base (6) que está unido al husillo de plastificación e inyección (2), y un elemento exterior (7) que es susceptible de efectuar al menos un movimiento de traslación y preferiblemente también un movimiento de rotación en relación con el cuerpo de base (6), para, en una primera posición (8), dar paso libre al flujo de masa fundida de plástico y, en una segunda posición (9), impedir el flujo de masa fundida de plástico;caracterizado por el hecho de que el elemento exterior (7) presenta al menos dos conductos (10, 11) de masa fundida que no están en conexión entre sí, y el cuerpo de base (6) presenta al menos un conducto (12) de masa fundida, estableciendo los al menos dos conductos (10, 11) de masa fundida del elemento exterior (7) junto con el conducto (12) de masa fundida del cuerpo de base (6) en la primera posición (8) una conexión fluídica entre la zona de rosca helicoidal (3) y la zona de la cámara anterior (4) del husillo, y siendo la conexión fluídica entre la zona de rosca helicoidal (3) y la zona de la cámara anterior (4) del husillo cortada en la segunda posición (9) por una zona (13) del cuerpo de base (6).
