Abstract

APARATO DE MOLDEO POR INYECCION CON UN ORIFICIO DE INYECCION CON UNA VALVULA PARA COINYECTAR Y/O INYECTAR SECUENCIALMENTE DOS FLUIDOS DIFERENTES A TRAVES DE UNA COMPUERTA (20) QUE ENTRAN EN UNA CAVIDAD (22). UN MIEMBRO DE ALFILER DE VALVULA ALARGADO (64) ES RECIBIDO EN UN MIEMBRO DE MANGUITO DE VALVULA ALARGADO (56) DE MANERA ALINEADA RESPECTO AL ORIFICIO DE INYECCION (20) Y UN MECANISMO ACCIONADOR INDEPENDIENTE LES HACE OSCILAR ROTATIVAMENTE ASI COMO AXIALMENTE PARA CONTROLAR EL FLUJO DE LOS FLUIDOS A TRAVES DEL ORIFICIO DE INYECCION. CADA UNO DE LOS MECANISMOS ACCIONADORES TIENE UN MIEMBRO DE BASTIDOR ACCIONADO POR UN PISTON (196,118) PARA PROPORCIONAR UN MOVIMIENTO ROTATIVO QUE DESPUES ES CONVERTIDO EN UN MOVIMIENTO AXIAL DEL MIEMBRO DE VALVULA CORRESPONDIENTE (56,64) ENTRE LAS POSICIONES DE ABIERTO RETRAIDO Y DE CERRADO HACIA ADELANTE. EN UN ASPECTO DE LA INVENCION, UNAS ROSCAS HELICOIDALES (104,126) FORMADAS EN LOS MIEMBROS DE VALVULA SE ENGANCHAN A UNOS DIENTES FIJOS QUE SE EXTIENDENHACIA ADENTRO DESDE LA BOQUILLA CIRCUNDANTE PARA CONVERTIR EL MOVIMIENTO ROTATIVO DE CADA UNO DE LOS MIEMBROS DE VALVULA EN UN MOVIMIENTO AXIAL CORRESPONDIENTE. UNOS TRANSDUCTORES DE POSICION LINEAL COLOCADOS EN LOS MIEMBROS DE BASTIDOR PROPORCIONAN UN CONTROL PRECISO DE LOS MIEMBROS DE VALVULA. ESTE CONTROL PRECISO Y LA REDUCCION DE LA FUERZA REQUERIDA POR ESTOS MECANISMOS ACCIONADORES AXIALES ROTATIVOS MINIMIZAN EL DESGASTE RESULTANTE DEL ASENTAMIENTO REPETIDO DE LOS MIEMBROS DE VALVULA.
