Problems solved by technology

However, the thermal conductivity of nitrogen is low, which easily leads to large temperature gradients, poor temperature control accuracy and temperature control response, which affects product yield, thereby increasing production costs and reducing product quality
[0006] In addition, in the prior art, when the radius of the curved surface of the cover glass changes, the mold must be remade, so when changing the appearance design, it takes a very high mold cost, which greatly increases the production cost of the product

[0070] Such as Figure 1 to Figure 10 As shown in the figure, the molding device of the first embodiment includes three parts: peripheral system, control system and process molding system.

[0071] The peripheral system includes machine base, chamber 1, feeding mechanism, conveying mechanism, discharging mechanism and so on.

[0072] The control system can control the peripheral system and process molding system. The control system controls the peripheral system and the process molding system, including a temperature control module, a gas pressure control module, a material feed control module, a material discharge control module, and the like.

[0073] The process molding system includes a mold 200, a pre-processing module, a main molding module, a post-processing module, and the like.

[0074] The pretreatment module includes an auxiliary preheating chamber 2, and may also include a mold state adjustment mechanism or / and a mold state detection module.

[0154] Figure 11 A second embodiment of the invention is illustrated, comprising:

[0155] 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.

[0156] 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.

Abstract

The invention relates to a high-efficiency mobile terminal 3D protective glass cover thermocompression forming device. The high-efficiency mobile terminal 3D protective glass cover hot-press forming device of the present invention can realize the maximum output at the lowest cost per unit time when making several glass material protective glass covers with curved sides, and can improve the product by reasonably increasing the forming temperature. Yield, temperature control accuracy and temperature control responsiveness, temperature gradient and mold cost are reduced, and curved parts with various radii can be easily molded. Moreover, since a separate mold that is pressure-molded only for the molded part of the cover glass is provided And press molding only for the forming part of the flat glass, not only shortens the hot pressing molding time, but also reduces the overall mold cost because the mold material of the part contacting the glass is set to a high-grade material, and the separate structure adopted can be easily produced Molds for molding operations of various shapes.

Description

technical field [0001] The invention relates to a high-efficiency mobile terminal 3D protective glass cover hot-press molding device, especially a device that can achieve maximum output at the lowest cost per unit time, can improve product yield, reduce mold cost, and easily form several sides with Thermocompression molding device for 3D cover glass covers of smartphones with curved surfaces of various radii. Background technique [0002] At present, mobile terminals such as smartphones and tablet computers, especially smartphones, are gradually abandoning resin covers for protective covers made of glass, which improves the firmness and aesthetics and improves product quality. [0003] Although flat glass can be made into the required thickness by calendering rolls by extrusion method and mass-produced, but the glass cover glass with curved surfaces on several sides or three or four sides puts the base material into the lower mold and The upper mold constitutes the internal...
