Abstract

La présente invention concerne un dispositif de moulage qui est apte à une production à grande échelle tout en permettant de fabriquer une unité miroir ayant une bonne précision, un produit moulé, une unité miroir, et un procédé de moulage. Dans la présente invention, une fois une résine solidifiée, lorsqu'une matrice mobile MD est séparée par rapport à une filière fixe, une tige angulaire AP pousse un support SDc d'une matrice coulissante SD vers l'extérieur tout en se rétractant par rapport à une ouverture BSa, et par conséquent se déplace dans une direction X et une direction Y dans laquelle la matrice coulissante SD se sépare de la filière fixe FD. La matrice coulissante SD s'arrête au moment où la tige angulaire AP sort d'un trou cylindrique SDd, mais dépasse une distance L correspondant à une partie en contre-dépouille d'un produit moulé MP dans cet état, et la matrice coulissante SD s'est déplacée d'une distance suffisante pour extraire le produit moulé, et le produit moulé peut ainsi être extrait.
