Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of glass processing equipment, and in particular relates to glass hot bending molds and glass production lines. Background Technology
[0002] In recent years, tempered glass has been widely used in various industries due to its superior safety and surface strength compared to other types of glass, providing strong safety guarantees for various sectors. In the automotive glass processing field, especially in the production of rear windshields, tempered glass is the most common production method and is widely used. Simple single-curved glass, such as window glass, does not require molds and can be produced directly using the roller conveyor in a furnace to adjust the curvature. However, complex double-curved glass requires specialized molds for processing and production. The structure and manufacturing quality of the molds are particularly important to the quality of the final product.
[0003] The mold structure for making curved glass typically includes a forming frame, which works in conjunction with a matching punch. First, the glass to be formed is placed on the forming frame. Then, a pushing mechanism drives the punch to move and close with the forming frame, bending the heated glass into a curved shape. However, the existing forming frame is fixed in position, often resulting in misalignment with the punch. This leads to poor fit of the final glass spherical surface, affecting surface quality.

[0034] Please see Figures 1 to 3This application provides a glass hot bending mold, comprising a forming frame 10, a mold frame 20 fixedly connected to the forming frame 10, a first slide 30 for supporting the mold frame 20, and a second slide 40 for supporting the first slide 30. The forming frame 10 is used to support the glass to be formed so as to bend the heated and softened glass into curved glass. The mold frame 20 is slidably connected to the first slide 30 along a first direction a, and the first slide 30 is slidably connected to the second slide 40 along a second direction b. The first direction a and the second direction b are set at an angle.
[0035] Understandably, the second slide 40, the first slide 30, the mold frame 20, and the forming frame 10 are arranged in sequence along the vertical direction, and the glass to be formed is placed on the forming frame 10.
[0036] Understandably, the glass hot bending mold of this application embodiment can be used in conjunction with a convex glass hot bending mold, that is, the glass hot bending mold of this application embodiment is a concave glass hot bending mold. In actual use, the glass hot bending mold of this application embodiment and the matching convex glass hot bending mold can be placed in a heating furnace, with the convex glass hot bending mold positioned above the glass hot bending mold of this application embodiment. The heating furnace is used to heat the glass to be formed placed between the glass hot bending mold of this application embodiment and the matching convex glass hot bending mold.
[0037] The glass to be formed is clamped between the glass hot bending mold and the convex glass hot bending mold of this embodiment, and bent into curved glass. The top surface of the glass hot bending mold of this embodiment is the forming frame 10, and the curvature of its surface facing away from the mold frame 20 is adapted to the curvature of the final formed curved glass. When the glass to be formed is heated in the heating furnace, it is in contact with the upper surface of the forming frame 10. The pushing mechanism drives the convex glass hot bending mold matched with the glass hot bending mold of this embodiment to close with the glass hot bending mold of this embodiment, so that the heated glass to be formed is bent into shape, and finally bent into curved glass.
[0038] The glass hot bending mold provided in this application can adjust the movement of the forming frame in the first direction a and the second direction b by adjusting the first slide 30 and the second slide 40, so that the forming frame 10 can be moved to align with the matching punch, thereby improving the surface quality of the final formed glass and increasing the versatility of the glass hot bending mold.
[0039] In some embodiments, the first slide block 30 is provided with a first slide groove 31 extending along a first direction a, the mold frame 20 is connected to a first slider 51, the first slider 51 is slidably connected to the first slide groove 31, the second slide block 40 is provided with a second slide groove 41 extending along a second direction b, the first slide block 30 is connected to a second slider 52, the second slider 52 is slidably connected to the second slide groove 41.
[0040] In this embodiment, the first slider 51 is slidably connected to the first slide groove 31, and the second slider 52 is slidably connected to the second slide groove 41, thereby making the sliding of the mold frame 20 on the first slide block 30 smoother, and the sliding of the first slide block 30 on the second slide block 40 smoother.
[0041] Specifically, in the embodiments of this application, the first slide 30 and the second slide 40 can be hollow steel pipe structures. The steel pipe structure extends in a certain direction, and the top surface of the steel pipe structure is provided with a long strip-shaped groove that communicates with the internal cavity of the steel pipe structure, thereby forming the first slide groove 31 or the second slide groove 41. The processing technology is simple, and there are many ways to obtain raw materials, which can improve production efficiency and reduce costs.
[0042] Specifically, the first slider 51 and the second slider 52 can be block-shaped structures with a smaller thickness in the middle and a larger thickness at both ends. The middle part with a smaller thickness contacts the groove opening of the first slide groove 31 or the second slide groove 41, and one end with a larger thickness extends into the interior of the first slide block 30 or the second slide block 40, while the other end with a larger thickness protrudes outside the first slide block 30 or the second slide block 40. This ensures that the sliding of the first slider 51 and the second slider 52 is smooth, while making the state of the first slider 51 and the second slider 52 more stable.
[0043] In other possible implementations, raised slide rails can also be provided on the first slide block 30 and the second slide block 40, and the first slider 51 and the second slider 52 can be sleeved on the slide rails, which can also achieve the function of sliding connection.
[0044] In some embodiments, the first direction a and the second direction b are perpendicular to each other, thereby making the glass hot bending mold more regular and improving its aesthetics. Understandably, the first slide 30 extends along the first direction a, and the second slide 40 extends along the second direction b, that is, the first slide 30 and the second slide 40 are perpendicular to each other.
[0045] In some embodiments, the molding frame 10 includes two first side frames 11 spaced apart from each other and two second side frames 12 connected between the two first side frames 11. The two second side frames 12 are spaced apart, and two second slide blocks 40 are spaced apart. The two second slide blocks 40 are respectively positioned corresponding to the two first side frames 11.
[0046] Understandably, the two first side frames 11 and the two second side frames 12 form a closed frame structure. The two second slides 40 are respectively set corresponding to the two first side frames 11. The two first side frames 11 are set between the two second slides 40, which not only makes the support of the forming frame 10 more stable, but also makes the movement of the forming frame 10 along the second direction b more stable, preventing the forming frame 10 from deviating.
[0047] Furthermore, each second slide 40 can be connected to multiple first slides 30. Specifically, each second slide 40 can be connected to two first slides 30, with the two first slides 30 respectively disposed on both sides of the corresponding second slide 40, and the two first slides 30 respectively close to the two second side frames 12. Further, the two first slides 30 are symmetrical about the center line of the second slide 40. Of course, in other possible embodiments, the number of first slides 30 connected to each second slide 40 can also be three, four, five, or more; this application does not limit this to a single possibility.
[0048] In some embodiments, the glass hot bending mold further includes a plurality of first connecting rods 61 connecting two second slides 40 and a plurality of second connecting rods 62 connecting adjacent two first connecting rods 61, the second connecting rods 62 being used to support the first slides 30.
[0049] By setting multiple first connecting rods 61 and multiple second connecting rods 62, not only can the structural strength of the second slide block 40 be improved, but the second connecting rods 62 can also support the first slide block 30, thereby preventing the first slide block 30 from shifting when moving.
[0050] Specifically, two second connecting rods 62 are respectively provided on opposite sides of the first slide block 30. The two second connecting rods 62 support the left and right ends of the first slide block 30 respectively, thereby preventing the first slide block 30 from shifting to the left and right sides during movement.
[0051] Specifically, the first connecting rod 61 extends along the first direction a, and the second connecting rod 62 extends along the second direction b. The first connecting rod 61 and the second connecting rod 62 can be perpendicular to each other.
[0052] In some embodiments, the glass hot bending mold further includes a telescopic support 70 connected between the mold frame 20 and the first slide 30. The telescopic support 70 is slidably connected to the first slide 30 and is used to support the mold frame 20. The telescopic support 70 can extend and retract in the vertical direction to adjust the height of the mold frame 20 relative to the first slide 30.
[0053] The height of the mold frame 20 can be adjusted by the telescopic support seat 70. Therefore, the glass hot bending mold of this application embodiment can not only adjust the position of the forming frame 10 in the horizontal direction, but also adjust the height of the forming frame 10 in the vertical direction, which further improves the adjustment range of the forming frame 10. It has multiple degrees of freedom of adjustment and can be flexibly adjusted according to actual needs, thereby improving the versatility and adaptability of the glass hot bending mold.
[0054] In some embodiments, the telescopic support 70 includes a fixed rod 71 connected to the mold frame 20 and a sleeve 72 sleeved outside the fixed rod 71. The fixed rod 71 is slidably connected to the sleeve 72 in the vertical direction, which simplifies the adjustment method and improves the adjustment efficiency.
[0055] Furthermore, the sleeve 72 has a plurality of fixing holes 721 that cooperate with the fixing rod 71. The plurality of fixing holes 721 are arranged at intervals along the length of the sleeve 72, and the fixing holes 721 are used to lock the fixing rod 71 onto the sleeve 72.
[0056] Understandably, the fixing hole 721 can cooperate with the fixing component. Through the fixing hole 721, the fixing component can lock the fixing rod 71 into the sleeve 72, thereby improving the stability of the telescopic support 70 during use and preventing it from loosening, falling off, or tilting due to external forces. Specifically, the fixing component is a limit bolt and a nut. Of course, the fixing component can also be a limit pin and an elastic protrusion, etc.
[0057] In some embodiments, the distance between two adjacent fixing holes 721 on the sleeve 72 along the length direction of the sleeve 72 is equal; of course, in other possible embodiments, the distance between two adjacent fixing holes 721 on the sleeve 72 is arranged in an arithmetic or geometric sequence along the length direction of the sleeve 72, so that it can be quickly adjusted for different needs and improve the adaptability of the telescopic support 70.
[0058] In some embodiments, a plurality of adjustable support feet 80 are connected between the molding frame 10 and the mold frame 20. The plurality of adjustable support feet 80 are distributed around the molding frame 10. The adjustable support feet 80 are telescopic structures to adjust the support angle of the molding frame 10.
[0059] Understandably, the forming frame 10 is a ring-shaped strip. The number and spacing of the adjustable support feet 80 can be set according to the actual shape and size of the glass to be formed. By adjusting the length of each adjustable support foot, the curvature of the forming frame 10 can be adjusted to match the arc of the final formed curved glass. Furthermore, when the size and weight of the glass to be formed are large, more adjustable support feet 80 can be added to enhance the supporting force on the forming frame 10.
[0060] Specifically, the adjustable support foot 80 includes a screw and a nut. One end of the screw is connected and fixed to the surface of the molding frame 10, and the other end of the screw is screwed to the mold frame 20. The nut is located on the mold frame 20 and abuts against the mold frame 20.
[0061] This application also proposes a glass production line, which includes a glass hot bending mold. The specific structure of the glass hot bending mold is as described in the above embodiments. Since this glass production line adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.
[0062] In summary, the glass hot bending mold provided in this application can adjust the movement of the forming frame in the first direction a and the second direction b by adjusting the first slide 30 and the second slide 40, so that the forming frame 10 can be moved to align with the matching punch, thereby improving the surface quality of the final formed glass and enhancing the versatility of the glass hot bending mold.
[0063] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art.
