[0035] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0036] In the present disclosure, "inner and outer" refers to the inner and outer of the profile of the corresponding component, unless otherwise stated. In addition, it should be noted that the terms such as "first", "second" and the like are used to distinguish one element from another. Among them, the first direction X can be understood as the width direction of the curved glass hot bending mold, the second direction Y can be understood as the length direction of the curved glass hot bending mold, and the third direction Z can be understood as the height direction of the curved glass hot bending mold.

[0037] According to one embodiment of the present disclosure, as shown in Figures 1-5 , a curved glass hot bending mold is provided. The curved glass hot bending mold can include a first mold body 1 and a second mold body 2. The first mold body 1 can include a forming cavity 11 and a first stop structure 12 located laterally of the forming cavity 11. The second mold body 2 can include a forming protrusion 21 corresponding to and cooperating with the forming cavity 11, and a first cooperating structure 22 corresponding to the first stop structure 12. The forming protrusion 21 cooperates with the forming cavity 11 to heat bend a flat glass 200 into a curved glass. The first stop structure 12 cooperates with the first cooperating structure 22 for positioning the flat glass 200.

[0038] Through the above technical solution, the first stop structure 12 is additionally provided laterally of the forming cavity 11 of the first mold body 1. The first stop structure 12 can form initial positioning for the flat glass 200 placed on the first mold body 1 and can reduce the lateral movement of the flat glass 200 during the forming process, effectively reducing the problem of reduced yield due to deviation during heat bending forming of the flat glass 200.

[0039] In some embodiments, as shown in Figure 5 , the forming cavity 11 can include a first forming surface 111 and a second forming surface 112, and a bending line 113 extending therebetween along the first direction X. The first stop structure 12 includes at least two first stop pieces 121. The two first stop pieces 121 are respectively located on opposite sides of the second direction Y of the forming cavity 11, and the two first stop pieces 121, the first forming surface 111 and the second forming surface 112 form a bending space for placing the flat glass 200, wherein the second direction Y is perpendicular to the first direction X. The first stop structure 12 is configured as the first stop piece 121, which can save the material of the first stop structure 12 on the one hand, and on the other hand, the first stop structure 12 is configured as at least two first stop pieces 121, which can reduce the resistance during demolding, avoid the problem that the first stop piece 121 on the first mold body 1 and the second cooperating structure 23 of the second mold body 2 have too large a cooperation area, resulting in too high demolding resistance. Of course, it can be understood that the first stop structure 12 can also be configured as a continuous stop bar, etc., which is not limited here, and those skilled in the art can design and adjust according to the actual situation.

[0040] In some embodiments, such as Figures 6-8 As shown, the first stop 121 may include a stop seat 121a and a stop block 121b connected to the stop seat 121a. The stop seat 121a is detachably connected to the molding cavity 11. The stop block 121b is used to abut against the side of the flat glass 200 along the second direction Y. The detachable connection of the stop seat 121a to the molding cavity 11 facilitates the assembly and replacement of the first stop 121. It should be noted that the first stop 121 can be constructed in various models to adapt to the positioning of flat glass 200 of different sizes. For example, Figure 6 As shown, the stop block 121b and the stop seat 121a have the same thickness. Figure 7 As shown, the thickness of the stop block 121b is less than the thickness of the stop seat 121a. Figure 8 As shown, the thickness of the stop block 121b is greater than the thickness of the stop seat 121a.

[0041] In some embodiments, such as Figure 5 As shown, the molding cavity 11 has a side opening 114 in the second direction Y. A stop seat 121a is inserted into the insertion hole 114, causing a stop block 121b to protrude from the insertion hole 114. The first stop member 121 is detachably connected to the molding cavity 11 by inserting the stop seat 121a into the insertion hole 114. This connection method is reliable, and the process of opening the insertion hole 114 is relatively simple. Of course, it is understood that the stop seat 121a can also be detachably connected to the molding cavity 11 by bolts, clips, or other connection methods. This is not a limitation, and those skilled in the art can design and adjust according to actual conditions.

[0042] In some embodiments, the first mating structure 22 may include the same number of first mating holes 221 as the first stop 121. The first mating holes 221 are inserted into the stop block 121b. Constructing the first mating structure 22 as first mating holes 221 provides a reliable connection, and the process of creating the first mating holes 221 is relatively simple. Of course, it is understood that the first mating structure 22 may also be constructed as a mating groove, etc., and this is not limited thereto; those skilled in the art can design and adjust it according to actual conditions.

[0043] In some embodiments, such as Figure 5 and Figure 2As shown, the first mold body 1 can further include a second stop structure 13 located at the side of the first direction X of the forming cavity 11. The second mold body 2 can further include a second matching structure 23 corresponding to the second stop structure 13. The second stop structure 13 matches with the second matching structure 23 for positioning the flat glass 200 and reducing the lateral movement of the flat glass 200 in the first direction X during the forming process. The positioning effect of the flat glass 200 can be further improved by the second stop structure 13. Illustratively, the second stop structure 13 can be configured as a plug-in part, and the two sides of the forming cavity 11 along the second direction Y can be provided with plug-in holes for the plug-in part to be inserted. Correspondingly, the second matching structure 23 can be configured as a second matching hole, and the second matching hole matches with the plug-in part.

[0044] In some embodiments, as shown in Figure 4 As shown, the curved glass hot bending mold can further include a positioning structure 3. The positioning structure 3 can include a positioning part 31 provided on any one of the first mold body 1 and the second mold body 2, and a matching part 32 provided on the other one of the first mold body 1 and the second mold body 2. The positioning structure 3 can make the first mold body 1 and the second mold body 2 reliably and accurately engaged when the first mold body 1 and the second mold body 2 are engaged with each other to hot bend the flat glass 200, thereby further improving the yield of the curved glass. Further, the positioning structure 3 is provided on both sides along the first direction X. Such an arrangement can improve the reliability of positioning.

[0045] In some embodiments, the positioning part 31 can be configured as a positioning protrusion extending from one of the first mold body 1 and the second mold body 2 toward the other one along the third direction Z, and the matching part 32 can be configured as a positioning groove recessed from the other one of the first mold body 1 and the second mold body 2 away from the one along the third direction Z. The positioning manner of the positioning protrusion and the positioning groove can avoid increasing the space occupied by the curved glass hot bending mold in the height on the basis of realizing positioning.

[0046] In some embodiments, as shown in Figure 4 As shown, the curved glass hot bending mold can further include an opening mold structure 4. The opening mold structure 4 can include a first opening mold groove 41 provided on the first mold body 1, and / or a second opening mold groove 42 provided on the second mold body 2. The design of the opening mold structure 4 facilitates the demolding of the first mold body 1 and the second mold body 2 after hot bending forming. Further, the opening mold structure 4 is provided on both sides along the second direction Y. Such an arrangement can improve the reliability and stability during opening mold.

[0047] In some embodiments, as shown in Figure 1As shown, the side of the first mold body 1 away from the forming cavity 11 and the side of the second mold body 2 away from the forming protrusion 21 are both provided with a plurality of inclined avoidance grooves 5. It should be noted that the curved glass hot bending mold needs to be pushed into the hot bending machine for heating, and the outer surface of the curved glass hot bending mold, i.e. the side of the first mold body 1 away from the forming cavity 11 and the side of the second mold body 2 away from the forming protrusion 21, needs to be in contact with the inner wall surface of the hot bending machine. When the outer surface of the curved glass hot bending mold is a plane, the outer surface will have a large adsorption force with the flat inner wall surface of the hot bending machine, thereby hindering the pushing. Therefore, in order to make the curved glass hot bending mold not disturbed by the adsorption force during the pushing process, the side of the first mold body 1 away from the forming cavity 11 and the side of the second mold body 2 away from the forming protrusion 21 are both provided with a plurality of inclined avoidance grooves 5 in the embodiment, which can reduce the adsorption force to a certain extent and ensure the normal pushing of the curved glass hot bending mold.

[0048] In some embodiments, the inclination angle of the avoidance groove 5 can be 40°-45°, and the distance between any two adjacent avoidance grooves 5 can be 25mm-35mm. Preferably, the inclination angle of the avoidance groove 5 is 45°, and the distance between any two adjacent avoidance grooves 5 can be 30mm. Controlling the inclination angle of the avoidance groove 5 and the distance between any two adjacent avoidance grooves 5 within the above range can make the avoidance groove 5 reduce the adsorption force to the maximum extent and ensure the normal pushing of the curved glass hot bending mold.

[0049] The preferred embodiments of the present disclosure are described in detail above with reference to the drawings, but the present disclosure is not limited to the specific details in the above-described embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

[0050] In addition, it should be noted that each specific technical feature described in the above-described specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, various possible combination manners are not described again in the present disclosure.

[0051] In addition, various different embodiments of the present disclosure can also be combined in any appropriate manner, as long as they do not deviate from the idea of the present disclosure, and they should also be considered as disclosed by the present disclosure.
