Abstract

ESTE INVENTO SE REFIERE A UN SISTEMA DE MOLDEO POR INYECCION CON DOS BOQUILLAS CALENTADAS MONTADAS EN TANDEM. LA BOQUILLA TRASERA ES CONSIDERABLEMENTE MAS LARGA QUE LA BOQUILLA DELANTERA Y TIENE UN TALADRO FUNDIDO CUYO DIAMETRO ES BASTANTE MAS GRANDE QUE EL DEL TALADRO FUNDIDO EN LA BOQUILLA DELANTERA. LA BOQUILLA DELANTERA MENOR TIENE UNA CULATA ASEGURADA A SU EXTREMO TRASERO CON UNA FINA PESTAÑA QUE SE EXTIENDE HACIA DELANTE Y HACIA ATRAS PARA TOMAR CONTACTO CON LA PARTE POSTERIOR DE UN NUCLEO DE MOLDEO, PARA ASEGURAR DICHA BOQUILLA DELANTERA CON LA PARTE ANTERIOR DEL NUCLEO DE MOLDEO. LA CARA TRASERA DE LA CULATA TIENE UN ASIENTO ALREDEDOR DEL NUCLEO DE MOLDEO PARA RECIBIR EL SALIENTE CILINDRICO DE UNA PUERTA INSERTADA MONTADA EN EL EXTREMO DELANTERO DE LA BOQUILLA TRASERA. SE PRODUCE ADEMAS UNA EXPANSION TERMAL DE LA BOQUILLA TRASERA MAYOR, MEDIANTE EL DESLIZAMIENTO DEL SALIENTE DE LA PUERTA INSERTADA EN SU ASIENTO. LA BOQUILLA DELANTERA MENOR TIENE UNA PARTE DEL ELEMENTO CALENTADOR ELECTRICO EN UN SALIENTE, PARA CONTROLAR LA TEMPERATURA EN EL AREA DE LA PUERTA.
