Abstract

SE PRESENTA UN NUEVO METODO PARA HACER POSIBLE EL MOLDEADO POR SOPLADO DE ESTIRAMIENTO EN UNA BANDA DE TEMPERATURA PREFERIBLE PARA EL POLIETILENO, CAPAZ DE LIBERARSE A UNA TEMPERATURA SUPERFICIAL ADECUADA TANTO PARA LA LIBERACION DE UNA PROFORMA COMO PARA EL SUBSECUENTE MOLDEADO POR SOPLADO DE ESTIRAMIENTO, DESCONECTANDO EL TROQUEL DE NUCLEO Y LA PROFORMA CON ANTELACION MEDIANTE EL USO DE LA PRESION DE UN GAS. ESTO PARA EL MOLDEADO A INYECCION DE UNA PROFORMA PREDETERMINADA LLENADO UN MOLDE DE INYECCION CON POLIETILENO FUNDIDO, LIBERANDO LA PROFORMA DE LA CAVIDAD DEL TROQUEL DEL MOLDE DE INYECCION MIENTRAS UNA PARTE DE LA BOCA DE LA PROFORMA ES MANTENIDA POR EL LABIO DEL TROQUEL, Y TRANSFIRIENDO LA PROFORMA AL INTERIOR DE UN TROQUEL DE SOPLADO PARA EL MOLDEADO POR ESTIRAMIENTO EN UN MOLDE HUECO DE UN PRODUCTO DE PAREDES FINAS. EL GAS SE HACE ENTRAR DE FORMA FORZADA AL INTERIOR DEL LIMITE DEL TROQUEL Y DE LA PROFORMA, ANTES DE SEPARAR LA PROFORMA DEL MOLDE DE INYECCION, PARA AISLAR LA PAREDINTERIOR DE LA PROFORMA DEL TROQUEL DEL NUCLEO. LA SEPARACION SE EFECTUA MIENTRAS QUE EL INTERIOR DE LA PROFORMA NO ESTA COMPLETAMENTE FRIA Y SE ENCUENTRA TODAVIA A ALTA TEMPERATURA, Y EN UNA BANDA DE TEMPERATURA EN LA CUAL LA TEMPERATURA SUPERFICIAL DE LA PROFORMA JUSTO ANTES DE LA LIBERACION OSCILA ENTRE 80 (GRADOS) Y 90 (GRADOS) C. EL PASO DE MOLDEADO POR SOPLADO DE ESTIRAMIENTO SE REALIZA DENTRO DEL INTERVALO DE TIEMPO ANTES DE QUE LA TEMPERATURA SUPERFICIAL DE LA PROFORMA QUE ES ELEVADA POR EL CALOR INTERNO DE LA PROFORMA ALCANCE 120 (GRADOS) C.
