[0063] Figure 1 to Figure 10 A first embodiment is illustrated,

[0064] Inside the chamber 1 where nitrogen gas is continuously injected, the mold 200 composed of the first lower mold 220 and the first upper mold 210 and filled with the plate glass 201 made of tempered glass is sequentially transferred, and sequentially formed according to the preheating, molding, The order of cooling is the auxiliary preheating chamber 2, the first preheating part 3, the second preheating part 4, the third preheating part 5, the forming part 6, the first cooling part 7, the second cooling part 8, the auxiliary cooling chamber 9,

[0065] The first preheating part 3, the second preheating part 4, the third preheating part 5, the molding part 6, the first cooling part 7, and the second cooling part 8 place a plurality of lower heating plates 11a to 11a of the mold 200. The lower heating plate 11f is installed on the inner bottom surface of the chamber 1, and the upper heating plate 12a to the...

[0112] Figure 11 A second embodiment of the invention is illustrated, comprising:

[0113] Curved surface molding frame 50 is equipped with curved surface 51 at one or both ends, and the plate-shaped material 52 in the preheated state is placed on the upper surface; fixed part 60 is driven by actuator 61 to move up and down and has the ability to hold the material when forming. 52 is fixed at one end of the fixed rod 62; the pressing part 70 has a pressing piece 72, which is driven by the actuator 71 to move up and down and exerts a biased load on one side of the material 52 during molding, so that the material 52 and the curved surface Part 51 is in close contact to realize curved surface molding.

[0114] The second embodiment constituted in this way does not use a mold body composed of upper and lower molds, but utilizes a curved surface forming frame 50 with an open top to bend and shape the curved surface of the cover glass.

[0115] The above-mentioned fixing part 60 ...

Abstract

The invention relates to a protective glass cover forming device for a mobile phone and a mold for forming, wherein the protective glass cover is provided with a curved surface part at one side or two sides. According to the protective glass cover forming device with a curved surface part at one side or two sides for the mobile phone and the mold for forming provided by the utility model, mold cost is reduced and curved surface parts with various radiuses are easily molded. Furthermore, because a separated mold which only molds through pressurizing the molding parts of the protective glass cover and only pressurizing the molding parts of flat panel glass, not only is shape molding time reduced, but also integral mold cost is reduced because metal of a part which contacts with the glass is high-grade material. The separated structure can be easily manufactured to molds which correspond with molding operation of various shapes.

Description

technical field [0001] The present invention relates to a mobile phone cover glass molding device with curved surfaces on one side or both sides and a molding mold, in particular to a cover glass made of glass material with curved surfaces on one side or both sides A protective glass cover molding device and molding mold for mobile phones that reduce mold costs and easily mold curved surfaces with various radii on one or both sides of the curved surface when covering the cover. Background technique [0002] At present, the mobile phone cover is gradually replacing the resin cover and using the glass material protective glass cover which improves the firmness and appearance and improves the product quality. [0003] Flat glass can be mass-produced by extruding to a desired thickness with calender rolls, but for cover glass made of glass with curved surfaces on one or both sides, the base material is put into a mold consisting of a lower mold and an upper mold. Concrete in-ho...
