Abstract

UN PROCEDIMIENTO PARA FORMAR UN ARTICULO POR MEDIO DE LA INYECCION DE MATERIALES DE PLASTICO EN UN MOLDE, CONSISTE EN LAS ETAPAS DE: PROPORCIONAR UNA HERRAMIENTA DE MOLDEO (11) QUE DEFINE EN SU ESTADO CERRADO UNA CAVIDAD DE MOLDE, ESTANDO ADAPTADA LA HERRAMIENTA DE MOLDEO PARA PODERSE EXPANDIR PARCIALMENTE A PARTIR DE UN VOLUMEN DE INYECCION (FIG. 2), Y RECIBIR UNA CARGA DE MATERIAL DE PLASTICO HASTA UN VOLUMEN FINAL MAYOR (FIG. 3) QUE DETERMINA LA FORMA DE TERMINACION CONFORMADA DEL ARTICULO, TENIENDO POR LO MENOS LA HERRAMIENTA DE MOLDEO UN ELEMENTO DESPLAZABLE (171, 172), QUE ESTA ADAPTADO PARA SER RETIRADO Y AUMENTAR EL VOLUMEN DE LA CAVIDAD DE MOLDE, ESTANDO REPRESENTADA LA DIFERENCIA ENTRE LOS VOLUMENES DE INYECCION Y FINAL, MEDIANTE UN VACIO MOSTRADO EN LA CAVIDAD DE MOLDE CUANDO SE RETIRA EL ELEMENTO DESPLAZABLE; CERRANDO LA HERRAMIENTA DE MOLDEO PARA DELIMITAR EL VOLUMEN DE INYECCION; INYECTANDO EN EL VOLUMEN DE INYECCION UNA MEZCLA DE MATERIALES DE PLASTICO, QUE CONSTA DE UN POLIMERO BASICO Y DE UN ADITIVO FORMADOR DE ESPUMA; RETIRAR EL ELEMENTO DESPLAZABLE (171, 172) PARA PERMITIR QUE EL MATERIAL DE PLASTICO OCUPE LA FORMA DEL VOLUMEN FINAL; Y ABRIR EL MOLDE Y EXPULSAR EL ARTICULO DE TERMINACION CONFORMADO; EN DONDE SE REALIZA LA RETIRADA CON RETRASO SUSTANCIALMENTE MINIMO AL RELLENAR EL ESPACIO DE INYECCION, POR LO QUE EN LA RETIRADA TIENE LUGAR UNA FORMACION DE ESPUMA DE RAPIDA EXPANSION DENTRO DEL VACIO.
