Description

Technical Field

[0001] This utility model belongs to the field of glass hot bending forming, specifically relating to a glass hot bending template, mold and glass hot bending furnace. Background Technology

[0002] Existing glass hot bending typically involves heating and softening flat glass in a glass hot bending furnace before shaping it in a mold. While the glass is heated to its softening point, the mold temperature also reaches that high temperature. After the glass is bent and shaped, it needs to be cooled and annealed in the furnace to form the glass product. During this process, the mold repeatedly works in this rapid heating and cooling environment, which makes it prone to cracking.

[0003] Therefore, there is a market demand for designing a glass hot bending template that can prevent cracking and has a long service life. Utility Model Content

[0019] Figure 2 This is a schematic diagram of a fiber blanket.

[0020] The components are: 1. Template body; 2. Fiber blanket; 3. Adhesive layer. Detailed Implementation

[0021] A glass hot bending furnace includes a furnace body and a glass hot bending mold disposed in the furnace body. Depending on the different glass products and different glass hot bending processes, the glass hot bending mold usually includes an upper mold and / or a lower mold. When the glass reaches the hot bending conditions, the hot bending operation is completed through the glass hot bending mold.

[0022] The upper template and / or lower template include a glass hot bending template, the specific structure of which is as follows.

[0023] like Figure 1 As shown, the glass hot bending template includes a template body 1 in the shape of a cube or cuboid, and a ring of high-temperature resistant heat-insulating fiber blanket 2 bonded along the four perimeters of the template body 1 by a high-temperature resistant adhesive layer 3.

[0024] The template body 1 is a machinable ceramic plate with a high temperature resistance of 1200 degrees Celsius. In this embodiment, the ceramic plate of model Alsay 1300HS-P3 is used, which is made of 44% alumina, 53% silicon oxide, and 3% iron oxide or zirconium oxide. The template body 1 has a shape structure corresponding to glass products (not shown), such as an arc surface or curved surface set on the upper or lower surface of the template body 1.

[0025] The high-temperature resistant adhesive layer 3 is formed by coating and drying a high-temperature adhesive with a high temperature resistance of 1400 degrees Celsius. In this embodiment, the high-temperature adhesive is Arser high-temperature refractory mortar ACP-150. Alternatively, an adhesive with a high temperature resistance of 1800 degrees Celsius or an adhesive with a high temperature resistance of 1600 degrees Celsius can also be selected.

[0026] Fiber blanket 2 is a ceramic fiber blanket with a high temperature resistance of 1400 degrees Celsius. Alternatively, a polycrystalline fiber blanket with a high temperature resistance of 1500 degrees Celsius can be selected.

[0027] The outer surface of the fiber blanket 2 is coated with an anti-oxidation coating, which is a silicon-based ceramic coating layer.

[0028] In this embodiment, the 1300HS-P3 ceramic plate, 1400 adhesive, ceramic fiber blanket, and polycrystalline fiber blanket are all available on the market and will not be described in detail here.

[0029] Glass hot bending template manufacturing process: Apply a layer of high-temperature adhesive to the periphery of the template body, and at the same time, evenly apply a layer of high-temperature adhesive to the smooth surface of the cut high-temperature resistant insulation fiber blanket 2. Completely cover and paste the high-temperature resistant insulation fiber blanket 2 with the high-temperature adhesive to the four sides of the template body, and put the pasted glass hot bending template into an oven to dry. The drying temperature of the oven is 100 degrees to 150 degrees. After drying, the high-temperature adhesive forms a high-temperature resistant adhesive layer, which bonds the high-temperature resistant insulation fiber blanket to the template body.

[0030] Glass hot bending templates, by covering the template body with a high-temperature resistant insulation fiber blanket along the perimeter, provide insulation for the template body, effectively preventing cracking of the template body in working environments with rapid heating and cooling, resulting in a longer service life and reduced production costs.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
