The present disclosure relates to a thermoforming method, a thermoforming mold, and a thermoforming device. The method comprises: providing a glass sheet to be processed at a softening point temperature and above; providing a thermoforming mold which comprises a male mold, a female mold arranged above the male mold and matched therewith, and a limiting block for limiting the female mold from deviate from the male mold, wherein the female mold comprises a central body module and a female mold frame surrounding the central body module and matched therewith; a first pressurizing process, wherein the central body module and the male mold are matched to press a central plane portion of the glass sheet; and a second pressurizing process, wherein the female mold frame and the male mold are matched to press a peripheral portion of the glass sheet so that the peripheral portion is bent and molded relative to the central plane portion; wherein the central plane portion is always pressed by the central body module in the second pressurizing process. The method improves the quality of a molded glass product and enhances the manufacturing yield of the glass product.

The present disclosure provides a thermoforming method and a thermoforming device for a glass product. The method comprises the following steps of: providing a thermoforming mold, wherein the thermoforming mold comprises a lower mold and an upper mold arranged above the lower mold and matched therewith, and providing a mold opening component; a pressurizing process, wherein a glass sheet placed in the thermoforming mold and at a softening point temperature and above is hot-pressed to form a glass product; a cooling process, wherein the glass product placed in the thermoforming mold is cooled, and when the temperature of the glass product drops to a glass point transformation temperature and below, the upper mold is opened by the mold opening component so that the upper mold is separated from the lower mold; and taking the glass product out when the temperature of the glass product in the thermoforming mold drops to a room temperature. The thermoforming method improves the molding quality of the glass product and enhances the manufacturing yield of the glass product.

A glass product forming mold includes a first mold and a second mold opposite to the first mold, a flat glass is formed into a three-dimensional glass structure after the first mold and the second mold are molded together. The first mold includes a first molding surface, a bottom surface, a side surface connecting the first molding surface and the bottom surface, and a first inclined surface; the second mold includes a second molding surface; and the first inclined surface extends to connect to the side surface from an edge of the first molding surface along a direction away from the first molding surface and the second mold. A thermal expansion coefficient of the first mold is smaller than that of the flat glass. Before complete cooling, the three-dimensional glass structure has been separated from the first molding surface, avoiding the deformation and rupture of the three-dimensional glass structure.

A mold includes a lower mold core and an upper mold core. The lower mold core has a first outside surface and a first molding surface including a first molding portion and a first supporting portion surrounding the molding portion. The upper mold core has a second molding surface opposite to the first molding surface and encloses a molding cavity with the first molding surface. The lower mold core includes a first gas inlet on the first outside surface, a first gas outlet on the first supporting portion, and a first gas channel in the lower mold core, the first gas channel connecting the first gas inlet and the first gas outlet. Gas flow out from the first gas outlet to separate the glass product from the lower mold core before the glass product is completely cooled down, which can avoid many adverse effects during the glass product process.

A glass product forming mold includes a mold body and a plurality of sliding blocks slidably mounted on the mold body and facing the glass product; each of the plurality of sliding blocks includes a first inclined surface; the plurality of sliding blocks are configured to be inserted between the glass product and the mold body through the plurality of the first inclined surfaces to separate the glass product from the mold body. The sliding blocks are driven to separate the glass product from the mold body, avoiding the deformation of raw glass products resulting from the uneven heat distribution, uneven shrinkage or excessive adhesion, and the glass products will not be interfered by the mold body during the process of cooling shrinkage, which reduces the risk of cracking of the glass product.
