Abstract

Procedimiento de moldeado por inyección de un conjunto de tabiques/aletas, caracterizado porque: - en una primera fase de moldeado, se efectúa el moldeado por inyección, en una primera impresión de un molde de bi-inyección y con la ayuda de brochas (4), de unas aletas (1) realizadas con unos ejes (3) esencialmente cónicos huecos, presentando una débil retenida y materializando los ejes de rotación (x-x'') los unos con respecto de los otros, - se desmoldea estas aletas, - se las transfiere en una segunda impresión del molde de bi-inyección por rotación del carro, - se introduce, en las cavidades cónicas de los ejes (3) obtenidas durante la primera fase de moldeado, unas brochas (5, 5'') permitiendo ensanchar los extremos (6) de estas cavidades, de forma a obtener así una deformación plástica permanente de los ejes (3) a este nivel, y - en una segunda fase de moldeado, se efectúa el sobremoldeado por inyección de los tabiques (2) al menos parcialmente alrededor de unos ejes huecos (3) de unas aletas (1) ensanchadas precedentemente por las brochas (5, 5'').Injection molding process of a set of partitions / fins, characterized in that: - in a first phase of molding, injection molding is carried out, on a first impression of a bi-injection mold and with the help of brushes (4 ), of fins (1) made with hollow essentially conical axes (3), presenting a weak retention and materializing the rotation axes (x-x '') with respect to each other, - these fins are demoulded, - they are transferred in a second impression of the bi-injection mold by rotation of the carriage, - brushes (5, 5 '') are introduced into the conical cavities of the shafts (3) obtained during the first molding phase. allowing to widen the ends (6) of these cavities, in order to obtain a permanent plastic deformation of the shafts (3) at this level, and - in a second molding phase, the injection molding of the partitions (2) is carried out ) at least partially around about e The holes (3) of fins (1) widened beforehand by the brushes (5, 5``).
