Abstract
Patente de Invenção: <B>"PROCESSO DE MOLDAGEM POR INJEçãO DE ELEMENTOS MóVEIS EM ROTAçãO, UNS EM RELAçãO AOS OUTROS"<D>. Processo de moldagem por injeção de um conjunto de mancais/aletas caracterizado pelo fato de que: - em uma primeira fase de moldagem, efetua-se a moldagem por injeção, em uma primeira impressão de um molde de bi-injeção e com o auxílio de pinos (4), das aletas (1) realizadas com eixos (3) essencialmente cónicos vazados, que apresentam uma pequena retenção e que materializam os eixos de rotação (x-x') dos elementos (1, 2) uns em relação aos outros. - desmolda-se essas aletas, - transfere-se as mesmas para uma segunda impressão do molde de bi-injeção por rotação do carro, - introduz-se, nas cavidades cónicas dos eixos (3) obtidos por ocasião da primeira fase de moldagem, pinos (5, 5') que permitem alargar as extremidades (6) dessas cavidades, de modo a obter assim uma deformação plástica permanente dos eixos (3) a esse nível, e - em uma segunda fase de moldagem, efetua-se a sobremoldagem por injeção dos mancais (2) pelo menos parcialmente em torno dos eixos vazados (3) das aletas (1) previamente alargados pelos pinos (5, 5').Invention Patent: <B> "MOLDING PROCESS FOR INJECTION OF MOVING ELEMENTS IN ROTATION, ONE IN RELATION TO OTHERS" <D>. Injection molding process of a set of bearings / fins characterized by the fact that: - in a first molding phase, injection molding is carried out, in a first impression of a bi-injection mold and with the aid of pins (4), of the fins (1) made with essentially conical hollow shafts (3), which have a small retention and which materialize the axes of rotation (x-x ') of the elements (1, 2) in relation to each other . - these fins are demoulded, - they are transferred to a second impression of the bi-injection mold by rotation of the carriage, - it is introduced into the conical cavities of the shafts (3) obtained during the first molding stage, pins (5, 5 ') that allow the ends (6) of these cavities to be widened, so as to obtain a permanent plastic deformation of the axes (3) at that level, and - in a second molding phase, overmoulding is carried out by injection of the bearings (2) at least partially around the hollow shafts (3) of the fins (1) previously widened by the pins (5, 5 ').
