Abstract

PRENSA HIDRAULICA PARA EL MOLDEO DE PIEZAS DE PLASTICO QUE COMPRENDEN PARTES ROSCADAS. CARACTERIZADA PORQUE COMPRENDE UN DISPOSITIVO DE DESENROSCADO CONTROLADO POR UN MOTOR HIDRAULICO CONECTADO AL CIRCUITO HIDRAULICO PRINCIPAL Y OPERADO POR DICHO CIRCUITO DURANTE LA ETAPA DE APERTURA DEL MOLDE; PORQUE EL DISPOSITIVO DE DESENROSCADO ESTA CONSTITUIDO ESENCIALMENTE POR UN MOTOR HIDRAULICO Y UNA PLACA DE SOPORTE DE MOLDE QUE COMPRENDE INTERIORMENTE LAS TRANSMISIONES DEL MOTOR Y EXTERIORMENTE COMPRENDE UN DISPOSITIVO CAPAZ DE TRANSMITIR EL MOVIMIENTO GIRATORIO DEL MOTOR HIDRAULICO A LOS MANDRILES DE ROSCADO; Y PORQUE EL DISPOSITIVO QUE TRANSMITE EL MOVIMIENTO GIRATORIO DEL MOTOR HIDRAULICO A LOS MANDRILES, SE DISPONE EN EL CENTRO DE LA PLACA DE SOPORTE DEL MOLDE.
