Abstract

Système sous vide composé d'un panneau de commande (11) et de chambres à vide (2, 2') formées en divisant horizontalement en deux parties l'intérieur d'une enceinte (1) allongée verticalement, pourvue de soupapes d'aspiration et de décharge, en une partie essentiellement médiane de l'enceinte. Lesdites chambres à vide, possèdent des portes (3, 3') formées de manière indépendante et pourvues de fenêtres de regard (4) en verre résistant à la pression d'air de manière à assurer une fermeture étanche à l'air. La chambre à vide supérieure (2) contient une cuvette (5) dans laquelle est placé un durcisseur, ainsi qu'une cuvette (6) pourvue d'un agitateur (7) recevant une solution de résine visqueuse crue. Les cuvettes (5, 6) sont supportées de manière à être inclinées vers l'avant. La cuvette (5) contenant le durcisseur est placée légèrement plus haut que la cuvette (6) de manière à permettre, en inclinant la cuvette (5) vers l'avant, de verser le durcisseur dans la cuvette agitatrice (6) qui est disposée légèrement au-dessous de la cuvette (5), et qui reçoit une solution crue essentiellemnt exempte de bulles d'air. Un entonnoir (8) et un tube (9) sont placés au-dessus de la cuvette agitatrice (6) de manière à s'étendre dans la chambre inférieure (2'), l'entonnoir (8) et le tube (9) étant utilisés pour injecter une solution crue agitée à laquelle on a mélangé le durcisseur, dans un moule en silicone. La chambre inférieure (2') contient un organe de levage (A) permettant d'ajuster la hauteur d'un moule, et pouvant être déplacé verticalement à la main, ainsi qu'une pluralité d'étagères (10). Le panneau de commande (11) comporte un groupe de commutateurs (13) installés à la surface et servant à exécuter automatiquement les étapes consistant à aspirer et décharger l'air, à créer le vide et à commander les différentes parties, à extraire les bulles du durcisseur et d'une solution de matière crue, à verser le durcisseur prédéterminé dans la solution de matière crue contenue dans la cuvette agitatrice (6) en inclinant la cuvette (5) vers l'avant, à mélanger la solution et le durcisseur tout en les agitant, et à injecter finalement la matière crue dans un moule aux silicones par l'intermédiaire de l'entonnoir inférieur (8) et du tube (9) en inclinant vers l'avant la cuvette agitatrice (6).
