Embodiment Construction
[0021] Such as figure 1 and figure 2 Shown is a schematic diagram of a three-dimensional glass 3 produced by using the mold 2 for preparing three-dimensional glass provided in the specific embodiment of the present invention and a cross-sectional view along the V-V direction. The three-dimensional glass 3 includes a curved panel 31 and a side arm 32 connected to the curved panel 31 and bent toward a direction corresponding to the concave surface of the curved panel 31 . The side arm 32 is smoothly connected with the arc panel 31 , and the projection of the inner edge of the side arm 32 relative to the arc panel 31 is located on the arc panel 31 . In other words, the bending angle of the side arm 32 in the three-dimensional glass 3 relative to the curved panel 31 exceeds 90 degrees. In this embodiment, the number of side arms 32 is four, which are respectively connected to the four sides of the curved panel 31 , so as to form a cover-shaped three-dimensional glass 3 together...

Abstract
The invention relates to a die for preparation of three-dimensional glass. The three-dimensional glass comprises an arc panel and a side arm that is connected to the arc panel and bends toward a direction corresponding to the concave surface of the arc panel. Also, the side arm inner edge's projection relative to the arc panel is on the arc panel. The die comprises a die main body and sliding blocks. The die main body includes a die core and sliding chutes. The die core is defined with a molding zone consistent with the arc panel in shape, and the sliding chutes are disposed at the periphery of the die core's molding zone correspondingly to the side wall. The sliding blocks are disposed corresponding to the sliding chutes. Each sliding block includes a sliding block main body and a protrusion part protruding toward the molding zone from the sliding block main body, the sliding block main bodies can slide along the sliding chutes so as to make the sliding blocks detachably clamped on the die core, and meanwhile the protrusion parts protrude at the inner edge of the molding zone. The invention also provides a method for preparation of three-dimensional glass by the die.
Description
technical field [0001] The invention relates to a mold for preparing three-dimensional glass and a method for preparing three-dimensional glass using the mold. Background technique [0002] Common electronic products are usually provided with a glass casing on the surface to protect the display module inside the product. At present, most of the glass casings are in the shape of flat plates, and there will inevitably be seams on the upper surface of electronic products. On the other hand, a mechanism with a certain width must be reserved around the electronic product to hold the flat glass, so the top surface of the electronic product cannot be fully utilized. Therefore, three-dimensional or curved glass is more often applied to glass housings of electronic products. The main difficulty in preparing three-dimensional glass used in electronic products is that when the bending angle of the glass side exceeds 90 degrees, the glass product will be tightly wrapped in the middle ...
