Abstract
LA INVENCION TIENE POR OBJETO UN PROCEDIMIENTO PARA LA FABRICACION DE PIEZAS SOPLADAS TRIDIMENSIONALES CON POCA PRODUCCION DE RESIDUOS, QUE EMPLEA UNA MAQUINA DE MOLDEO POR SOPLADO CON UNA CABEZA EXTRUSORA O COEXTRUSORA QUE PRODUCE UNA PIEZA BRUTA TUBULAR, UN CORTADOR DE TUBOS, UN DISPOSITIVO INVERSOR A MODO DE PINZA QUE INTRODUCE LA PIEZA BRUTA EN UN NIDO DE MOLDEO (8) INCORPORADO EN UNA HERRAMIENTA DE MOLDEO POR SOPLADO (1), ASI COMO UN GRABADO, UNA LANZA SOPLADORA Y UN DISPOSITIVO DE RECOGIDA DE LA PIEZA ACABADA. EL PROCEDIMIENTO RACIONALIZA LA FABRICACION SIEMPRE Y CUANDO LA PIEZA BRUTA AGARRADA POR EL DISPOSITIVO INVERSOR SEA INTRODUCIDA EN UN NIDO DE MOLDEO ABIERTO POR EL DESPLAZAMIENTO DE UNOS ELEMENTOS CORREDEROS (4A, 4B; 5A, 5B) PROVISTOS DE CAVIDADES DE NIDO DE MOLDEO COMPLEMENTARIAS (8A, 8B) E INTEGRADO EN UN MOLDE DE SOPLADO (1) SIN UNIDAD DE CIERRE Y, UNA VEZ CERRADOS LOS ELEMENTOS CORREDEROS POR SU PROPIA FUERZA, LA PIEZA SEA INFLADA A LA FORMA DEL ARTICULO ACABADO. LA MAQUINADE LA INVENCION DISPONE DE UN MOLDE DE SOPLADO (1) CON ELEMENTOS CORREDEROS (4A, 4B; 5A, 5B) QUE GENERAN POR SI MISMOS LA FUERZA DE CIERRE Y ESTAN DOTADOS DE CAVIDADES DE NIDO DE MOLDEO (8A, 8B) COMPLEMENTARIAS Y ENFRENTADAS ENTRE ELLAS.
