Abstract
UN SISTEMA DE MOLDEO A INYECCION TIENE UN SOPORTE NEUMATICO DE DOBLE ACCION Y UN MECANISMO DE MANOBRA DE AGUJA DE VALVULA DE PIÑON. EL TUBO DE FUNDICION DERIVA EN UN COLECTOR QUE FORMA UNA ENTRADA CENTRAL Y FLUYE A LO LARGO DE LA AGUJA DE VALVULA EN UN CILINDRO CENTRAL A LA BOQUILLA DEL RESPIRADERO. UN PIÑON DENTADO MONTADO EN UNA RANURA DEL COLECTOR. EL MIEMBRO PIÑON ACCIONA UN MIEMBRO SOPORTE DENTADO A LO LARGO DE UNA LINEA RECTA EN LA RANURA DEL COLECTOR Y TAMBIEN ACCIONA UN CABEZAL ALARGADO DE LA AGUJA DE VALVULA AL MIEMBRO SOPORTE. FUERZAS LATERALES DESDE EL MIEMBRO PIÑON SON ABSORBIDOS POR CONTACTO DE LAS SUPERFICIES DEL MIEMBRO SOPORTE CONTRA SUPERFICIES DEL MIEMBRO SOPORTE CONTRA SUPERFICIES DE ADAPTACION DEL COLECTOR Y/O UN ANILLO DE LA AGUJA DE VALVULA Y NO SON TRANSMITIDAS A DICHA AGUJA. ESTO EVITA UN DESIGUAL USO Y EL CUMULO DE DEPOSITOS DE FUNDICION ALREDEDOR DE LA AGUJA QUE DE OTRA FORMA PODRIA RESULTAR DE UNA MALA FUNDICION.
