Abstract

L'invention porte sur un dispositif d'extraction qui, lors de l'extraction d'un article moulé en résine en forme de plaque, tel qu'une plaque guide de lumière, exécutée au moyen d'une aspiration, peut éviter que l'article moulé en résine ne se déforme. Le dispositif d'extraction (1), qui aspire une plaque guide de lumière (2), laquelle est un article moulé en résine qui est moulé dans un moule, et extrait ensuite la plaque guide de lumière (2) du moule, comporte un seul corps d'aspiration (3) qui entre en contact avec la plaque guide de lumière (2), et une pompe à vide (4) qui produit une pression négative lorsqu'elle aspire et qui retient la plaque guide de lumière (2) en contact avec le corps d'aspiration (3), et le corps d'aspiration (3) comprend un corps poreux interconnecté possédant de l'élasticité. Il est possible d'aspirer sur toute la surface de la plaque guide de lumière (2) au moyen du corps d'aspiration (3) et il est donc possible d'éviter la déformation, même si la plaque guide de lumière (2) est relativement mince.
