Abstract

APARATO DE INYECCION DE MATERIAS PLASTICAS, ELASTOMERAS O ANALOGAS. EN EL INTERIOR DE UN FORRO FIJO (5) SE DESLIZA UN FORRO MOVIL (7) DELIMITANDO UNA CAMARA DE VOLUMEN VARIABLE (26). EL FORRO MOVIL LLEVA EN SU INTERIOR UN SISTEMA (9) DE ALIMENTACION DE MATERIA QUE COMUNICA CON LA CAMARA DE VOLUMEN VARIABLE A TRAVES DE UN ORIFICIO (12) PROVISTO DE VALVULA. LOS MEDIOS DE ACCIONAMIENTO (14 A 20) DEL FORRO MOVIL PARA INYECCION DE MATERIA EN EL MOLDE SON SOLIDARIOS CON EL FORRO FIJO Y EL CONJUNTO DEL APARATO DE INYECCION SE DESPLAZA CON RELACION AL MOLDE.
