Abstract

Un dispositivo de moldeado por inyección para producir por lo menos una cabeza de tubo con un hombro de tubo y un cuello de tubo formados a continuación de la misma con una abertura de extrusión que incluye un molde que define un espacio hueco en el molde (37) y una boquilla (15) que coopera con el molde. La boquilla (15) tiene un cuerpo de la boquilla (49) y una aguja de válvula (51) desplazable en el cuerpo de la boquilla (49) en la dirección del eje longitudinal del tubo. La aguja de la válvula consta de un cuerpo de aguja de válvula (53) y una cabeza terminal de la aguja de válvula (55). La aguja de la válvula (51) está circundada por un primer canal de flujo (63), a través del cual puede impulsarse un primer componente de material (64). La abertura (72) de la boquilla (15) se produce en una posición retraída de la aguja de la válvula (51) cerrada por la cabeza de la aguja de la válvula (55), y en una posición de desplazamiento hacia adelante de la aguja de la válvula (51) es liberada por la cabeza de la aguja de la válvula (55), en la que en la posición de desplazamiento hacia adelante de la aguja de la válvula (51) se forma una compuerta de salida anular (72), la cual, junto con un espacio anular (83) del molde que sirve como compuerta de entrada produce una conexión fluida en el espacio hueco del molde (37).An injection molding device for producing at least one tube head with a tube shoulder and tube neck formed thereafter with an extrusion opening including a mold defining a hollow space in the mold (37 ) and a nozzle (15) that cooperates with the mold. The nozzle (15) has a nozzle body (49) and a valve needle (51) movable in the nozzle body (49) in the direction of the longitudinal axis of the tube. The valve needle consists of a valve needle body (53) and a valve needle end head (55). The valve needle (51) is surrounded by a first flow channel (63), through which a first material component (64) can be urged. The opening (72) of the nozzle (15) occurs in a retracted position of the valve needle (51) closed by the head of the valve needle (55), and in a position of forward movement of the valve Valve needle (51) is released by the valve needle head (55), wherein in the valve needle forward displacement position (51) an annular outlet gate (72 ), which, together with an annular space (83) of the mold that serves as an inlet gate, produces a fluid connection in the hollow space of the mold (37).
