Abstract

SE PRESENTA UN APARATO PARA EL MOLDEADO TERMICO A INYECCION QUE TIENE UNA CAVIDAD QUE FORMA UN ENCASTRE SEPARADO DE LA BOQUILLA RECALENTADA. LA CAVIDAD QUE FORMA EL ENCASTRE TIENE UNA COMBINACION DE ELEMENTOS CALENTADORES Y REFRIGERADORES QUE SE EXTIENDEN ALREDEDOR DE UN AGUJERO CENTRAL QUE SE ENCUENTRA DELANTE DEL ORIFICIO DE INYECCION. LA CAVIDAD QUE FORMA EL ENCASTRE TIENE UN ELEMENTO ELECTRICO CALENTADOR INTEGRAL CON UNA PARTE INTERIOR QUE TIENE UN NUMERO DE BOBINAS ADYACENTES CERCA DEL ORIFICIO DE INYECCION. LA ENERGIA QUE ALIMENTA EL ELEMENTO CALENTADOR SE CONMUTA SUCESIVAMENTE A ESTADOS DE ENCENDIDO Y APAGADO DURANTE EL CICLO DE INYECCION, Y LA COMBINACION DE LOS SUCESIVOS CALENTAMIENTOS Y ENFRIAMIENTOS EN LA CAVIDAD QUE FORMA EL ENCASTRE MEJORA LA RESPUESTA TERMICA Y ACORTA EL TIEMPO DE CADA CICLO.
