Abstract

Appareil de moulage par injection de résine durcissant par faisceau d'énergie, capable de conférer n'importe quel motif de précision bidimensionnelle à une surface de film, etc. et dont l'efficacité de production est remarquable. L'appareil de moulage par injection (110) à résine durcissant par faisceau d'énergie comprend un moule métallique (112), des moyens de mesure d'injection (114) permettant de doser la résine durcissant par faisceau d'injection et son injection dans un cavité (122) du moule métallique, et une source de faisceau d'énergie (116) destinée à irradier le moule métallique. Ce moule métallique comporte une fenêtre (128) formant au moins une partie de sa cavité qui permet à tout faisceau d'énergie émis par la dite source de traverser la fenêtre pour aller irradier l'intérieur de la cavité du moule métallique, caractérisé en ce que l'ouverture et la fermeture de l'orifice d'injection (136) et de l'orifice de décharge (138) peuvent être obtenues par des déplacements alternatifs d'une tige (144) et d'une tige (146)à l'intérieur du canal d'alimentation en résine (132) et du canal de décharge (234) dans une matrice fixe (118).
