Title:
MOLD FOR SHAPING GLASS PRODUCT, SHAPING APPARATUS, AND PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/138975
Kind Code:
A1
Abstract:
Disclosed are a mold for shaping a glass product, a shaping apparatus, and a processing method. The mold for shaping a glass product comprises a first mold and a second mold arranged opposite to each other. After combination of the first mold and the second mold, a planar glass material is shaped into a three-dimensional glass structure. The first mold comprises a first shaping surface, a bottom surface and a side surface connecting the first shaping surface and the bottom surface. The second mold comprises a second shaping surface. The first mold further comprises a first slanted surface extending from an edge of the first shaping surface in a direction away from the first shaping surface and the second mold and connected to the side surface. A thermal expansion coefficient of the first mold is less than a thermal expansion coefficient of the planar glass material. In the mold for shaping a glass product of the present invention, the three-dimensional glass structure is separated from the first shaping surface before being completely cooled, thereby ensuring uniform cooling of the three-dimensional glass structure. Moreover, the first mold does not obstruct contraction of the three-dimensional glass structure, thereby preventing deformation and breakage of the three-dimensional glass structure.
