Example Embodiment

[0026] In order to make the purpose, technical solutions, and advantages of the present application clearer, the technical solutions of the present application will be described clearly and completely in conjunction with specific embodiments of the present application and the corresponding drawings.

[0027] See figure 1 As shown, the molding die 10 for the glass-ceramic back cover of the present application includes a lower die 11 and an upper die 12 fitted above the lower die 11.

[0028] The lower mold 11 includes a lower mold plate 110 and a cavity 111 formed on the lower mold plate 110. At least two outer peripheries of the cavity 111 are provided with horizontal stepped portions 112. The cavity 111 includes a parallel or arc-shaped bottom cavity 114 and arc-shaped two ends 113 adjacent to the step portion 112. The arc-shaped two ends 113 have a greater arc than the bottom cavity 114. The horizontal position of the step portion 112 is lower than the upper surface of the lower ...

Abstract

The invention relates to a glass ceramic rear cover forming method which comprises the following steps: S10, providing a forming die, putting a glass ceramic plate in a lower die of the forming die, and assembling an upper die above the lower die, and S20, performing heat treatment on the forming die and the glass ceramic plate to soften the glass ceramic plate to be fit with a cavity below, and at the same time, applying high pressure above the glass ceramic plate through the upper die till the glass ceramic plate is completely fit with the surface of the cavity, wherein the cavity is arranged in the lower die. The invention further provides a die.

Description

technical field [0001] This application relates to the fields of glass products and communications, in particular to a method and mold for forming a hand glass-ceramic back cover suitable for 5G terminals. Background technique [0002] With the approach of 5G communication, the entire mobile phone appearance industry is undergoing major changes. At present, traditional mobile phone appearance parts are mainly made of metal materials, but metal materials have a shielding effect on mobile phone signals, and there is a conflict with 5G communication. At the same time, the market has higher and higher requirements for the appearance and texture of mobile phone appearance parts. Glass and Ceramic materials stand out under this series of development trends. Compared with ceramic materials, glass has the advantages of wide source of raw materials, low hardness, easy surface treatment, richer colors, etc., and has great market potential. [0003] Glass-ceramics undergoes a certain...
