Abstract

SE PRESENTA UN MOLDE DE INYECCION MULTICAVIDAD (1), PARA EL MOLDEADO A INYECCION SIMULTANEO DE UNA PLURALIDAD DE ARTICULOS MULTICAPA QUE TIENE UN SISTEMA DE DISTRIBUCION EN CALIENTE SIMPLE (19) PARA EL SUMINISTRO SECUENCIAL PARA UN PRIMER Y UN SEGUNDO MATERIAL FUNDIDO A LAS CAVIDADES (3) DEL MOLDE, SIENDO SUMINISTRADOS CADA UNO DE ESTOS MATERIALES A TODAS LAS CAVIDADES EN CANTIDADES IGUALES. LA INVENCION TAMBIEN SUMINISTRA UNA VARILLA DE NUCLEO (5) PARA CADA CAVIDAD EN LA QUE EXISTE UNA CONCAVIDAD, AL LADO DEL PUNTO DE ENTRADA DE LOS MATERIALES AL INTERIOR DE LA CAVIDAD, PARA EVITAR QUE EL PRIMER MATERIAL INYECTADO EN EL CICLO DE INYECCION SEA ELIMINADO DEL EXTREMO DE LA VARILLA DEL NUCLEO POR EL SEGUNDO MATERIAL DE INYECCION, UNA OBLEA DEL PRIMER MATERIAL INYECTADO EN LA ZONA DEL CUELLO DE LA PROFORMA PARA COMPENSAR LAS VARIACIONES DE LA TEMPERATURA EN LAS CAVIDADES Y EL MATERIAL SE DISTRIBUYE A LAS DIFERENTES PARTES DEL MOLDE Y EL USO DE LA PRIMERA PARTE DE LA CANTIDAD MEDIDA DEL PRIMER MATERIAL A SER INYECTADO DEL PROXIMO CICLO DE INYECCION PARA SELLAR LA PROFORMA EN EL FINAL DEL CICLO DE INYECCION.
