Abstract

L'invention porte sur un appareil de formation de moule pour lentille ophtalmique, doté d'une nouvelle structure permettant d'obtenir un alignement axial de haute précision entre une matrice de formation de surface antérieure et une matrice de formation de surface postérieure, et donc d'atteindre une précision d'usinage excellente. L'invention propose un appareil comprenant un premier gabarit de montage (12) formant support pour la matrice de formation de surface antérieure (16) et un second gabarit de montage (14) formant support pour la matrice de formation de surface postérieure (18) et incluant également, dans le premier gabarit de montage (12), un élément récepteur (20) supportant le premier gabarit de montage (12) et un organe de réglage du noyau (28) autorisant un déplacement relatif du premier gabarit de montage (12) depuis l'élément récepteur (20) dans une direction à peu près orthogonale par rapport à la direction de mise en concordance des matrices.
