Abstract
EN LA ELABORACION DE RECIPIENTES DE PAREDES HUECAS A BASE DE MATERIAL TERMOPLASTICO EN UNA MAQUINA DE FUNDICION DE INYECCION SE INCLUYEN DURANTE EL PROCESO DE INYECCION UN ELEMENTO DE NUCLEO EN EL ESPACIO HUECO DEL MOLDE, QUE DESPUES DE LA SOLIDIFICACION DEL MATERIAL SINTETICO TERMOPLASTICO SE EXTRAE BAJO LA FORMACION DE UN ESPACIO HUECO DE PARED. PARA PODER CONSEGUIR UN ESPACIO HUECO DE PARED CERRADO EN UN RECIPIENTE SEGUN PROCESO DE FUNDICION, SE PROPONE QUE EL ELEMENTO DE NUCLEO SE ELABORE A PARTIR DE UN CASQUILLO INTERIOR Y UN CASQUILLO EXTERIOR, SIENDO DESPLAZABLES AMBOS UNO CONTRA OTRO POR MEDIO DE UNA UNIDAD CILINDRO-EMBOLO CONFIGURADO A PARTIR DE UN SEGUNDO CASQUILLO INTERIOR Y EXTERIOR DE TAL MODO, QUE EN LA EXTRACCION DEL ELEMENTO DE NUCLEO SE ABRE UN VOLUMEN ANULAR QUE SE ENCUENTRA ENTRE EL CASQUILLO INTERIOR Y EXTERIOR EN EL ESPACIO HUECO DE PARED A SER FORMADO, Y ALIMENTANDOSE CON GAS A PRESION EL CANAL DE AFLUENCIA QUE SE ENCUENTRA ENTRE EL CASQUILLO INTERIOR Y EL EXTERIOR. POR MEDIO DE UN EMBOLO DE FONDO QUE CONFIGURA EL FONDO DEL RECIPIENTE SE CIERRA MEDIANTE DESPLAZAMIENTO CON MASA DE PLASTICO AUN EN ESTADO PLASTICO DE FORMA RADIALMENTE HACIA EL EXTERIOR Y SE CIERRA CON ELLO LA ZONA DEL FONDO CON EL ESPACIO HUECO DE PARED.
