Abstract

APARATO PARA MOLDEAR POR INYECCION PLASTICO, QUE CONSTA DE UN ELEMENTO (18) DE INTRODUCCION DEL PLASTICO (19) POR UNA O MAS ABERTURAS (43) EN UN MOLDE (13) Y ELEMENTOS (26,34) PARA INTRODUCIR GAS A PRESION A TRAVES DE UNA ABERTURA SEPARADA (44) EN EL MATERIAL PLASTICO QUE LLENA EL MOLDE, CREANDO UNA CAVIDAD CON GAS (25) EN EL PLASTICO. A CONTINUACION SE ELIMINA LA PRESION DENTRO DE LA CAVIDAD ANTES DE ABRIRSE EL MOLDE. EL ELEMENTO DE ALIMENTACION DE GAS ELIMINACION DE LA PRESION CONSTA, EN DICHA ABERTURA SEPARADA (44), DE UNA PUERTA DE VALVULA (42) QUE SE ABRE DIRECTAMENTE AL MOLDE, UNA VALVULA (26) QUE ABRE Y CIERRA LA ANTERIOR PUERTA, UN ELEMENTO (34) DE SUMINISTRO DE GAS A PRESION AL MOLDE. ESTE ALIMENTA EL GAS A TRAVES DE LA VALVULA (26) ENCONTRANDOSE LA PUERTA DE VALVULA EN POSICION CERRADA PARA CREAR UNA CAVIDAD. TERMINADA LA OPERACION DE MOLDEO SE SUSPENDE EL SUMINISTRO DE GAS A PRESION Y EL GAS EXISTENTE EN LA CAVIDAD DEL MOLDE PUEDE CONDUCIRSE A LA ATMOSFERA POR UN MOVIMIENTO DELA VALVULA QUE ABRE LA PUERTA CITADA.
