３Ｄカバーガラス、およびその成形用金型

摘要

To provide a 3D cover glass molding die capable of suppressing the occurrence of wrinkles during press molding.SOLUTION: The 3D cover glass molding die having a flat central portion and having a curved surface portion in at least a part of peripheral portion includes a pair of convex die and concave having a press surface A corresponding to the central portion and a press surface B corresponding to the curved surface portion. When the closest distance between the press surfaces A of the convex die and the concave die during press molding is D and the closest distance between the press surfaces B of the convex die and concave die during the press molding is D1, predetermined conditions are satisfied to the thickness of a final-product 3D cover glass.SELECTED DRAWING: Figure 4
