Abstract

Perfeccionamiento en las prensas de inyección con cabezal giratorio, para material termoplástico, caracterizados porque la prensa comprende un par de semimoldes, uno de los cuales está fijado a la bancada de la máquina y el otro se desplaza y gira en al menos 180º alrededor de una eje soportado por dos columnas, presentando dicho semimolde giratorio que queda simétrico respecto a dicho eje, por lo menos en una de sus caras los espacios de inyección y hallándose previstos medios para determinar dicha rotación.
