Description

Technical Field

[0001] This invention relates to the field of curved steel glass lamination mold technology, specifically to a semi-circular arc-shaped glass lamination mold and its lamination method. 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, semi-circular 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 semi-circular curved glass, it is inconvenient to place an internal pressure vessel. If several sets of matching semi-circular 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 semi-circular 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. Summary of the Invention

[0003] To address the problems mentioned in the background art, the technical solution adopted by the present invention is: a semi-circular arc-shaped glass lamination mold, comprising: an arc-shaped frame, with inclined openings symmetrically arranged on both sides of the top of the arc-shaped frame, support columns arranged at the four corners of the arc-shaped frame, a pressure strip arranged at the lower end of the support column on one side of the arc-shaped frame, a first elastic pad arranged at the bottom of the pressure strip, a positioning rod fixedly connected to the bottom of the support column, a positioning hole opened on the side of the top of the support column facing the positioning rod, a limit frame fixedly connected to the outer side of the upper end of the support column facing the positioning hole, and a locking mechanism elastically inserted inside the limit frame for locking connection when multiple lamination molds are stacked, a second elastic pad arranged at the top of both the arc-shaped frame and the inclined opening, and a curved steel glass assembly placed on the top of the arc-shaped frame and the inclined opening through the second elastic pad.

[0004] As a preferred embodiment of the present invention, the locking mechanism includes an L-shaped locking rod, which slides through the center of the limiting frame. A limiting ring is provided at one end of the L-shaped locking rod inside the limiting frame. A spring is sleeved between the limiting ring and the limiting frame, and the L-shaped locking rod forms a pull-back plug-in locking structure through the spring.

[0005] As a preferred embodiment of the present invention, the curved steel glass assembly includes an inner layer of curved steel glass, an outer layer of curved steel glass, and a laminated layer. The laminated layer is bonded between the inner layer of curved steel glass and the outer layer of curved steel glass. The same end of the inner layer of curved steel glass and the outer layer of curved steel glass are tightly attached to the outside of the second elastic gasket on the inclined opening. The bottom side of the inner layer of curved steel glass is tightly attached to the second elastic gasket on the top of the arc frame.

[0006] As a preferred embodiment of the present invention, the positioning rod is fitted into the positioning hole, and an annular groove is formed on the lower circumference of the positioning rod.

[0007] As a preferred embodiment of the present invention, the insertion end of the L-shaped locking rod is arc-shaped, matching the annular groove, and the L-shaped locking rod extends into the positioning hole and engages with the annular groove.

[0008] As a preferred embodiment of the present invention, a support block is provided on the outer side of the limiting frame, and a notch is provided at the end of the support block.

[0009] As a preferred embodiment of the present invention, the L-shaped locking rod is located at one end outside the limiting frame and matches the notch. When the L-shaped locking rod is pulled outward, the outer rod body is vertically upward and engages with the notch for positioning.

[0010] As a preferred embodiment of the present invention, the bottom of the pressure strip has an arc-shaped structure, and the bottom end of the pressure strip is tightly attached to the top edge of the outer curved steel glass through a first elastic pad.

[0011] A method for simultaneously laminating multiple sets of semi-circular arc-shaped glass using the aforementioned semi-circular arc-shaped glass laminating mold, characterized by comprising the following:

[0012] S1. Place the preheated and rolled semi-circular curved steel glass assembly along the arc surface of the top of the arc frame, so that the inner curved steel glass in the semi-circular curved steel glass assembly is in close contact with the second elastic pad on the top of the arc frame, and the curved ends of the inner and outer curved steel glass are in close contact with the second elastic pad at the inclined opening 2.

[0013] S2. Complete the assembly of another set of curved frames and semi-circular curved steel and glass components using the method of S1;

[0014] S3. Raise the curved frame of S2 group that holds the curved steel glass component to be above the curved frame of S1 group, so that the positioning rods at the bottom of the four corner support columns of the curved frame are aligned and inserted into the positioning holes on the support columns of the S1 curved frame, thereby splicing and locking the upper and lower adjacent laminated molds. After the upper and lower adjacent laminated molds are spliced ​​and fixed, the pressure strip 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 through the first elastic pad.

[0015] S4. Place it in the autoclave, start the lamination process according to the laminated glass parameters, and after the autoclave is opened, cool it down and remove it from the autoclave to complete the simultaneous lamination of multiple sets of semi-circular arc-shaped glass.

[0016] In step S2, after the adjacent interlocking molds are spliced ​​together, the bent end of the L-shaped locking rod is moved out of the support block, and then the limiting ring is pushed under the action of the spring force. The limiting ring moves along with the L-shaped locking rod, and the L-shaped locking rod is locked into the annular groove on the positioning rod in the positioning hole.

[0017] The present invention has the following advantages: The inclined opening in the laminating mold of the present invention can quickly fit and hold the curved ends of the inner and outer curved tempered glass, which can effectively prevent the inner and outer curved tempered glass from misaligning when heated in the autoclave. The second elastic gasket further makes the glass and the mold fit tightly and fix it. The laminating mold adopts a stackable method, which allows the upper laminating mold to quickly dock, lock and position with the lower laminating mold. After docking, the pressure strip at the bottom of the upper laminating mold, together 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 the stability of the structure and the accuracy of positioning. After lamination, it is easy to disassemble and assemble, achieving accurate positioning, stable clamping and protection of the glass in one mold. The mold adopts a stackable method, which can effectively realize the lamination processing of multiple sets of identical or matched curved glass in the same autoclave at the same time.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] The invention will now be further described with reference to the accompanying drawings.

[0026] Please refer to the following: Figures 1-4This invention discloses a semi-circular 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.

[0027] Combination Figure 2 and Figure 3 As 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.

[0028] Combination Figure 4As 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.

[0029] A method for simultaneously laminating multiple sets of semi-circular arc-shaped glass using the aforementioned semi-circular arc-shaped glass laminating mold, characterized by comprising the following:

[0030] S1. Place the preheated and rolled semi-circular curved steel glass assembly along the arc surface of the top of the arc frame, so that the inner curved steel glass in the semi-circular curved steel glass assembly is in close contact with the second elastic pad on the top of the arc frame, and the curved ends of the inner and outer curved steel glass are in close contact with the second elastic pad at the inclined opening 2.

[0031] S2. Complete the assembly of another set of curved frames and semi-circular curved steel and glass components using the method of S1;

[0032] S3. Raise the curved frame of S2 group that holds the curved steel glass component to be above the curved frame of S1 group, so that the positioning rods at the bottom of the four corner support columns of the curved frame are aligned and inserted into the positioning holes on the support columns of the S1 curved frame, thereby splicing and locking the upper and lower adjacent laminated molds. After the upper and lower adjacent laminated molds are spliced ​​and fixed, the pressure strip 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 through the first elastic pad.

[0033] S4. Place it in the autoclave, start the lamination process according to the laminated glass parameters, and after the autoclave is opened, cool it down and remove it from the autoclave to complete the simultaneous lamination of multiple sets of semi-circular arc-shaped glass.

[0034] The principle of using the semi-circular arc-shaped glass lamination mold is as follows: the preheated and rolled curved glass assembly is placed along the arc-shaped surface of the top of the arc-shaped frame 1, so that the inner layer of curved glass 15 in the curved glass assembly is tightly attached to the second elastic pad 14 at the top of the arc-shaped frame 1, and the curved ends of the inner layer of curved glass 15 and the outer layer of curved glass 16 are tightly attached to the second elastic pad 14 at the inclined opening 2. In this way, the assembly of another set of arc-shaped frames 1 and curved glass assemblies is completed. Then, the other set of arc-shaped frames 1 holding curved glass assemblies is raised above the previous set of arc-shaped frames 1, so that the positioning rod 6 at the bottom of the corner support column 3 of the arc-shaped frame 1 is aligned and inserted into the... In the positioning hole 8 on the support column 3 of the previous set of arc frame 1, the bent end of the L-shaped locking rod 10 is then moved out from the support block 12, and then the limiting ring 11 is pushed under the elastic force of the spring 13. The limiting ring 11 moves along with the L-shaped locking rod 10, and the L-shaped locking rod 10 is engaged in the annular groove 7 on the positioning rod 6 in the positioning hole 8, so that the upper and lower adjacent laminated molds can 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.

[0035] The above fully achieves the following: the inclined opening in this laminating 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 dock, lock, and position with the lower laminating mold. After docking, 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 undergo lamination processing in the same autoclave at the same time.

[0036] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
