Elastic retroreflector

A forming die for the producing a retroreflector, wherein the retroreflector comprises an arrangement comprising a plurality of mirrored or totally reflective triples, each triple having first, second, and third side surfaces perpendicular to each other;

• wherein the first, second, and third side surfaces are disposed as cube corners;
• and wherein the retroreflector is produced by injection molding from a carrier material comprising an optically transparent silicone resin;
• wherein the forming die comprises:
• a die body delimited by a die surface;
• wherein the die surface has a plurality of triples;
• wherein each triple has first, second, and third forming surfaces that border on one another and intersect one another at an angle between 85° and 95°;
• wherein the first, second, and third forming surfaces of each triple come together in a triple center;
• wherein an axis of symmetry of the respective triple extends through the triple center;
• wherein the die body is heated;
• and
• wherein the triples of the die body have undercuts perpendicular to an unmolding direction that counter unmolding.
