Description

Technical Field

[0001] This utility model relates to the field of curved steel glass lamination mold technology, specifically to an arc-shaped glass lamination mold. Background Technology

[0002] The forming process of curved tempered glass includes pressure bending and hot bending. Pressure bending uses a pressure film to press hot glass into a certain shape. Hot bending involves heating glass to its softening temperature and allowing it to adhere to a bending mold under its own weight, or moving it towards an air-cushion heating furnace to form the glass. When laminating two curved pieces of glass, the process involves first laminating and preheating the tempered glass sheets, then placing the preheated and rolled glass onto a mold and securing it with steel straps. Finally, the secured laminated glass is pushed into an autoclave and opened according to the following parameters: pressure: 1.2 MPa, temperature: 135 degrees Celsius, time: 120 minutes. After opening, the glass is cooled and removed from the autoclave. Utilizing the adhesive and tensile strength of the interlayer, the flat tempered laminated glass is laminated into curved tempered laminated glass. Therefore, currently, curved tempered glass after preheating and rolling needs to be fixed to a mold using steel strips. The molds cannot be stacked. Due to the shape of the curved glass, it is inconvenient to place an internal autoclave. If several sets of matching curved glass need to be laminated simultaneously, it becomes even more difficult. Some molds are designed to be stackable, but disassembly and assembly are cumbersome and troublesome. Furthermore, precise positioning, stable clamping, and effective protection of the glass during lamination cannot be effectively achieved, resulting in poor practicality. Therefore, this paper proposes a curved glass lamination mold that is easy to stack and disassemble, provides stable clamping, and protects the laminated glass during molding, thus solving the problem.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] Please refer to the following: Figures 1-4 This utility model discloses an arc-shaped glass lamination mold, comprising: an arc-shaped frame 1, with inclined openings 2 symmetrically arranged on both sides of the top of the arc-shaped frame 1; support columns 3 arranged at the four corners of the arc-shaped frame 1; pressure strips 4 arranged at the lower end of the support columns 3 on one side of the arc-shaped frame 1; a first elastic pad 5 arranged at the bottom of the pressure strips 4; a positioning rod 6 fixedly connected to the bottom of the support columns 3; a positioning hole 8 opened on the top of the support columns 3 facing the positioning rod 6; a limit frame 9 fixedly connected to the outer side of the upper end of the support columns 3 facing the positioning hole 8; and a locking mechanism with elastic insertion inside the limit frame 9 for... When multi-layer laminated molds are stacked, a locking connection is established. The locking mechanism includes an L-shaped locking rod 10. The L-shaped locking rod 10 slides through the middle of the limiting frame 9. A limiting ring 11 is provided at one end of the L-shaped locking rod 10 inside the limiting frame 9. A spring 13 is sleeved between the limiting ring 11 and the limiting frame 9. The L-shaped locking rod 10 forms a pull-back insertion locking structure through the spring 13. A second elastic pad 14 is provided at the top of both the arc frame 1 and the inclined opening 2. A curved steel glass assembly is placed at the top of the arc frame 1 and the inclined opening 2 through the second elastic pad 14.

[0021] Combination Figure 2 and Figure 3As shown, the curved steel glass assembly includes an inner curved steel glass 15, an outer curved steel glass 16, and a laminated layer 17. The laminated layer 17 is bonded between the inner curved steel glass 15 and the outer curved steel glass 16. The same end of the inner curved steel glass 15 and the outer curved steel glass 16 are tightly attached to the outside of the second elastic gasket 14 on the inclined opening 2, so that the curved ends of the inner curved steel glass 15 and the outer curved steel glass 16 can be supported, limited, and protected at the same time. The bottom side of the inner curved steel glass 15 is tightly attached to the second elastic gasket 14 on the top of the arc frame 1. The positioning rod 6 is inserted into the positioning hole 8. The lower end of the positioning rod 6 has an annular groove 7. The insertion end of the L-shaped locking rod 10 is arc-shaped and matches the annular groove 7. The L-shaped locking rod 10 extends into the positioning hole 8 and is engaged with the annular groove 7. The first and second elastic gaskets are made of existing high-temperature resistant cotton materials with a certain degree of hardness, so they have a certain clamping force and a certain degree of elasticity when subjected to strong force.

[0022] Combination Figure 4 As shown, a support block 12 is provided on the outside of the limiting frame 9. The end of the support block 12 is provided with a notch. The L-shaped locking rod 10 is located outside the limiting frame 9, and one end of it matches the notch. When the L-shaped locking rod 10 is pulled outward, the outer rod is vertically upward and locked into the notch for positioning. Then, by simply bending one end of the L-shaped locking rod 10 and locking it into the notch on the support block 12, the L-shaped locking rod 10 can be pulled out from the positioning hole 8 for limiting. This makes it convenient and quick to insert or remove the positioning rods 6 on the two adjacent sets of laminating molds. The bottom of the pressure strip 4 is an arc-shaped structure. The bottom end of the pressure strip 4 is tightly attached to the top side of the outer curved steel glass 16 through the first elastic pad 5. In use, the upper laminating mold can not only quickly dock and lock with the lower laminating mold, but also, after docking, the pressure strip at the bottom of the upper laminating mold, together with the first elastic pad, can further press, fix and position the curved end of the curved steel glass component on the lower laminating mold. That is, the mold can be stacked.

[0023] Specifically, in use, this utility model simply requires placing the preheated and rolled curved glass assembly along the curved surface of the top of the curved frame 1, so that the inner curved glass 15 in the curved glass assembly is tightly attached to the second elastic pad 14 at the top of the curved frame 1, and the curved ends of the inner curved glass 15 and the outer curved glass 16 are tightly attached to the second elastic pad at the inclined opening 2. This completes the assembly of another set of curved frames 1 and curved glass assemblies. Then, the other set of curved frames 1 holding the curved glass assembly is raised above the previous set of curved frames 1, so that the positioning rod 6 at the bottom of the corner support column 3 of the curved frame 1 is aligned and inserted into the previous set. The L-shaped locking rod 10 is then moved from the support block 12 through the positioning hole 8 on the support column 3 of the arc frame 1. Then, under the action of the spring 13, the limiting ring 11 is pushed, and the limiting ring 11 moves along with the L-shaped locking rod 10, so that the L-shaped locking rod 10 is engaged in the annular groove 7 on the positioning rod 6 in the positioning hole 8. This allows the upper and lower adjacent laminated molds to be spliced ​​and fixed. Similarly, the opposite operation can be used to disassemble them. After the upper and lower adjacent laminated molds are spliced ​​and fixed, the pressure strip 4 at the bottom of the upper laminated mold is pressed against the top of the curved end of the curved steel glass component of the lower laminated mold by the first elastic pad 5.

[0024] This practical laminating mold fully achieves the following: The inclined opening in the mold can quickly fit and hold the curved ends of the inner and outer curved tempered glass, effectively preventing misalignment of the inner and outer curved tempered glass during heating in the autoclave. The second elastic gasket further ensures that the glass and the mold are tightly attached and fixed. The laminating mold adopts a stackable design, allowing the upper laminating mold to quickly connect, lock, and position with the lower laminating mold. After connection, the pressure strip at the bottom of the upper laminating mold, in conjunction with the first elastic gasket, can further press, fix, and position the curved ends of the curved tempered glass components on the lower laminating mold, thereby effectively ensuring structural stability and precise positioning. After lamination, it is easy to disassemble and assemble, achieving precise positioning, stable clamping, and effective protection of the glass in a single mold. The mold adopts a stackable design, which can effectively enable multiple sets of identical or matching curved glass to be laminated in the same autoclave at the same time.

[0025] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
