Abstract

EN UN DISPOSITIVO MOLDEADOR DE UNA MAQUINA DE FUSION A PRESION ES BLOQUEABLE UNA PLACA DE SUJECCION ALOJADA DESPLAZABLE DE LA COLUMNA DE GUIA, POR UN MECANISMO SOSTENEDOR. LA UNIDAD DE BLOQUEDO SE AFIANZA MEDIANTE EMBOLOS DE CIERRES HIDRAULICOS EN UN SOPORTE DE AFIANZAMIENTO EN EL QUE SE CONFORMA UN CILINDRO DE CIERRE Y SE CIMENTA LA COLUMNA DE GUIA. PARA SIMPLIFICAR LA PREPARACION DE LA UNIDADES HIDRAULICAS CONSISTENTES EN EMBOLOS Y CILINDROS DE CIERRE Y MEJORAR LA ESTANQUEIDAD SE PROPONE: COMFORMAR EL EMBOLO DE MANDO COMO EMBOLO DE INMERSION DIFERENCIAL; DISPONER EN EL INTERIOR DE LOS EMBOLOS DE INMERSION DIFERENCIAL UN EMBOLO DIFERENCIAL; UNIR FIJAMENTE EL VASTAGO DEL EMBOLO CON EL SOPORTE DE AFIANZAMIENTO Y ASENTAR EL EMBOLO DE INMERSION DIFERENCIAL CON EL VASTAGO DEL EMBOLO DIFERENCIAL. MEDIANTE EL DESPLAZAMIENTO DE LA SUPERFICIE DE EMBOLO DE LOS EMBOLOS DIFERENCIALES PROPORCIONADO POR LA UNIDAD DE BLOQUEO Y EL DESPLAZAMIENTO DE LA SUPERFICIE DE LOS EMBOLOS DIFERENCIALES DE INMERSIONASENTADOS POR LOS VASTAGOS DE LOS EMBOLOS DIFERENCIALES CON MEDIOS DE PRESION, SE PRODUCE UN PROCESO DE CIERRE DEL DISPOSITIVO DEL MOLDEADOR. A TRAVES DEL DESPLAZAMIENTO POR PRESION DE LA SUPERFICIE DEL EMBOLO DIFERENCIAL POR ACCIONES DE LAS UNIDADES DE BLOQUEO SE PRODUCE EL ARRANQUE DEL DISPOSITIVO MOLDEADOR.
