Abstract

Se describe una barra de obstrucción con boquilla de inyección (4) de máquinas para moldear recipientes de material plástico, proporcionada con un sistema de fijación conveniente para prevenir la separación de las partes que forman el pistón neumático de impulsión de la misma barra, el pistón es sometido a tensiones considerables durante la operación de máquina. Por lo tanto, la barra de acuerdo a la invención puede prevenir la unión del pistón, y por lo tanto también la fijación de la misma barra, reduciendo considerablemente el número de intervenciones de mantenimiento y por lo tanto aumentando el rendimiento de la máquina de moldeo.
