Zusammenfassung:	PURPOSE: A multi-layer mold device having a temperature control device of a digital mold for improving a quality of injection-molded articles is provided to secure the uniformity of refractive index and the dimensional stability by controlling temperatures of each layer individually. CONSTITUTION: A multi-layer mold device comprises a first mold layer, a second mold layer, a third mold layer, and an insulator layer. A cavity plane of the first mold layer forms a cavity(7), which is enough to make a desired form by inserting melted injection materials when doing a mold-spotting. The second mold layer encloses an outer surface of a first mold. The third mold layer encloses the outside of a second mold. The insulator layer is formed on a contact potion of the first and second mold.
