Abstract

LA PRESENTE INVENCION SE REFIERE A UN PROCESO Y UN APARATO PARA ARTICULOS DE PLASTICO CON MUROS FINOS PARA UN MOLDEO DE INYECCION. EN UNA PRIMERA INCORPORACION, EL APARATO COMPRENDE UNA CAVIDAD DE MOLDEAR (14) Y UN NUCLEO DE MOLDEAR (18) QUE DEFINEN UN ESPACIO DE CAVIDAD (19) CON LA FORMA DEL ARTICULO Y AL MENOS DOS COMPUERTAS DE INYECCION (32) ADYACENTES A UNA PORCION DEL ESPACIO DE LA CAVIDAD QUE DEFINE LA PORCION DEL REBORDE (30) A TRAVES DEL CUAL SE INYECTA EL PLASTICO MOLDEADO EN EL ESPACIO DE LA CAVIDAD (19). ESTE ACCESO DIRECTO PARA UN ACCIONAMIENTO DE COMPUERTAS DE REBORDE NO SACRIFICA LA ALINEACION DEL NUCLEO O DE LA CAVIDAD NI LOS MOVIMIENTOS DEL MOLDEO CONVENCIONAL A LO LARGO DEL EJE DE LA MAQUINA Y FORMA ARTICULOS DE PLASTICO QUE NO TIENEN PRACTICAMENTE NINGUN VESTIGIO DE COMPUERTA EN LA SUPERFICIE DE SELLADO DE REBORDE O EN EL PERIMETRO EXTERIOR DEL REBORDE. EN UNA SEGUNDA REPRESENTACION, ESTE APARATO INCLUYE UNA CAVIDAD DE MOLDEAR (14) Y UN NUCLEO DE MOLDEAR (18) QUE DEFINEN UN ESPACIO DE CAVIDAD (19) CON LA FORMA DEL ARTICULO. EL ESPACIO DE LA CAVIDAD TIENE UNA REGION (126) QUE SE EXTIENDE DE FORMA CIRCUNFERENCIAL Y QUE POSEE UN GROSOR MAYOR QUE EL DE UNA PORCION DE DEFINICION DE UN MURO LATERAL (122). ESTA REGION QUE SE EXTIENDE DE FORMA CIRCUNFERENCIAL (126) SE SITUA CON PREFERENCIA APROXIMADAMENTE EN EL PUNTO MEDIO DE LA PORCION DE DEFINICION DEL MURO LATERAL (122). AL MENOS DOS COMPUERTAS (32) INTRODUCEN INICIALMENTE DE FORMA DIRECTA Y SIMULTANEA MATERIAL PLASTICO EN LA PORCION QUE SE EXTIENDE DE FORMA CIRCUNFERENCIAL (126) DE FORMA TAL QUE SE MINIMICE LA CREACION DE CARGAS LATERALES Y CAMBIO DE NUCLEO. DESPUES DE RELLENAR LA REGION QUE SE EXTIENDE DE FORMA CIRCUNFERENCIAL (126), EL MATERIAL PLASTICO RECUBRE TODO EL ESPACIO DE LA CAVIDAD. DESPUES SE ENFRIA EL MATERIAL PLASTICO PARA FORMAR EL ARTICULO QUE SE DESEE.
