Abstract

PROCEDIMIENTO PARA EL MOLDEO DE PLASTICOS POR INYECCION EN EL QUE EL MATERIAL ES INTRODUCIDO EN EL MOLDE A TRAVES DE VARIOS BEBEDEROS. CONSISTE EN INTRODUCIR EL PLASTICO FUNDIDO A TRAVES DE UN PRIMER BEBEDERO (3), FORMANDOSE UN FRENTE DE CIRCULACION DE MATERIAL EN TODAS DIRECCIONES. CUANDO EL FRENTE CIRCULATORIO HA SOBREPASADO EL SEGUNDO BEBEDERO (4) SE ABRE UNA PRIMERA VALVULA (15), PERMITIENDO QUE EL PLASTICO FUNDIDO ENTRE EN EL MOLDE DE INYECCION A TRAVES DEL SEGUNDO BEBEDERO (4). EL MATERIAL FUNDIDO, RECIEN INTRODUCIDO, CALIENTA LIGERAMENTE EL MATERIAL FUNDIDO YA PRESENTE EN EL MOLDE Y SE MEZCLA CON EL. EL FRENTE DE CIRCULACION DE MATERIAL FUNDIDO, SIGUIENDO SU CURSO, SOBREPASA EL TERCER BEBEDERO (5) Y SE ABRE UNA SEGUNDA VALVULA (16), PERMITIENDO QUE EL PLASTICO ENTRE EN EL MOLDE DE INYECCION A TRAVES DEL TERCER BEBEDERO (5). EL PROCESO SE REPITE HASTA QUE EL MATERIAL FUNDIDO ALCANZA EL ULTIMO BEBEDERO.
