Device for moulding lenses and method of manufacturing lenses

A moulding device for forming lenses by moulding, said moulding device comprising:

• a moulding element comprising indentations formed in a face of the moulding element,
• a transparent plate held with respect to the moulding element so as to form, with the indentations, a cavity configured to allow the formation of a plurality of lenses,
• at least one injection passage configured to allow moulding product to be introduced into the cavity, the injection passage being arranged between the transparent plate and the moulding element,
• a moulding product injector arranged so as to allow moulding product to be introduced into the injection passage,
• wherein the injector is removable, and wherein said moulding device is configured so as to allow the injector to be removed while at the same time keeping the transparent plate held with respect to the moulding element,
• the moulding device further comprising an assembly member fixing the position of the transparent plate with respect to the moulding element before and after the injector is removed from the moulding device;
• wherein the assembly member comprises:
• at least one first fixing member,
• at least one second fixing member,
• two frames between which the transparent plate is arranged, said frames being assembled with one another by said at least one first fixing member so as to clamp the transparent plate, and the assembly of the two frames clamping the transparent plate being mounted to the moulding element by said at least one second fixing member.
