Description

Technical Field

[0001] The present application relates to the technical field of glass manufacturing, and in particular to a glass forming mold and forming method, and a glass processing device. Background Art

[0002] At present, large-sized inner-hole automotive glass with complex curvature usually adopts the mold pressing and tempering molding mode, and the molding method is: the glass is transmitted by ceramic rollers and heated in a heating furnace to a softened state, and then the glass is pressed into the desired shape through a mold; specifically, the glass is attached to the mold by vacuum suction, and after the pressing is completed, the molding ring moves to the bottom of the mold, the mold vacuum is released, and the molding ring catches the glass. In order to avoid the edge of the inner hole of the glass exceeding the standard, the design of the molding ring must provide an additional molding inner ring at the edge of the inner hole to fully support the inner contour edge of the glass in the hot-melt state, and prevent the inner contour from freely sagging and causing the surface to exceed the standard. After the molding ring completes the hot connection action, it is sent to the annealing area to complete quenching and tempering, and finally cooled to obtain a single piece of tempered glass.

[0003] However, with the increasing demand for intelligent and functional automotive glass, the structure of laminated glass is no longer limited to a simple two-piece laminate with the same outer contour. There are more and more designs that form a single-piece structure in the local area of ​​the interlayer, so that while having the advantages of laminated glass such as sound insulation and safety, the local single-piece structure area can also provide better transmission optical quality and functional windows, so that components such as vehicle cameras and sensors can be better integrated in this area. In this way, the laminated glass is composed of a perforated inner glass and a non-perforated outer glass. Since a set of molding molds in the above-mentioned traditional mold forming method can only produce one type of single-piece glass, two different sets of molding molds are required to process the perforated inner glass and the non-perforated outer glass separately. On the one hand, the number of molding molds used increases, resulting in increased manufacturing costs and difficult mold management; on the other hand, the perforated inner glass and the non-perforated outer glass are produced separately, making it difficult to control the matching degree of the two glass surfaces after bending, which is easy to cause poor overall optical quality after lamination. The hole edge of the perforated inner glass and the non-perforated outer glass are easy to form an opening, and there are many bubbles after lamination, resulting in a reduced yield rate. Summary of the invention

[0004] Based on this, it is necessary to provide a glass forming mold and forming method, and a glass processing device to address the problems of high manufacturing cost, difficult mold management, and poor quality of finished glass products.

[0005] In a first aspect of the present application, a glass forming mold is provided for alternately and continuously producing inner glass with holes and outer glass without holes, the glass forming mold comprising:

[0006] A male mold mechanism, the male mold mechanism comprising a first adsorption area and a second adsorption area; and

[0007] A female mold mechanism, wherein the female mold mechanism and the male mold mechanism are arranged opposite to each other along the height direction of the glass forming mold and surround a forming station, wherein the female mold mechanism comprises a first female mold component and a second female mold component, and both the first female mold component and the second female mold component can move toward or away from the male mold mechanism;

[0008] Among them, the first adsorption area is set corresponding to the hole-digging part of the glass, the first concave mold component is set corresponding to the outer contour of the hole-digging part of the glass, the second adsorption area is set corresponding to the non-hole-digging part of the glass, and the second concave mold components are all set corresponding to the outer contour of the glass. The glass forming mold has a first mold closing state and a second mold closing state. In the first mold closing state, the first adsorption area and the second adsorption area simultaneously adsorb the glass original piece, and the second concave mold component is molded with the convex mold mechanism to press the glass original piece into an outer piece of glass without a hole. In the second mold closing state, the second adsorption area adsorbs the glass original piece, and the first concave mold component and the second concave mold component are simultaneously molded with the convex mold mechanism to press the glass original piece into an inner piece of glass with a hole.

[0009] The glass forming mold of the present scheme is used in the processing occasions of producing the inner glass with holes and the outer glass without holes that constitute laminated glass; since the first adsorption area is set corresponding to the hole-digging part of the glass, the first die assembly is set corresponding to the outer contour of the hole-digging part of the glass, the second adsorption area is set corresponding to the non-hole-digging part of the glass, and the second die assemblies are all set corresponding to the outer contour of the glass, therefore during processing, the glass original pieces heated to a molten state are transported by the conveying mechanism one by one into the forming station of the glass forming mold, and after the current glass original piece arrives at the forming station, in response to the instruction of the first mold closing state, the system controls the first adsorption area and the second adsorption area to adsorb the glass original piece at the same time, and controls the second die assembly and the punch mechanism to close the mold so that the glass original piece can be pressed into the outer glass without holes, and then the outer glass without holes is moved out of the forming station to vacate the forming station; thereafter, the next glass original piece heated to a molten state is conveyed into the forming station The system controls the second adsorption area to adsorb the original glass sheet, and controls the first concave mold assembly and the second concave mold assembly to simultaneously close the mold with the convex mold mechanism, so that the original glass sheet can be pressed and formed into a perforated inner glass with a hole, and then the perforated inner glass is moved out of the forming station to vacate the forming station; the above processing steps are continuously repeated, so that only one set of glass forming molds can be used to continuously and alternately produce perforated inner glass and non-perforated outer glass. On the one hand, the number of molds used is saved, and the manufacturing cost and mold management difficulty are reduced. On the other hand, the perforated inner glass and the non-perforated outer glass are obtained by pressing with the same glass forming mold, so the two pieces of glass have the same shape and curvature after bending, and the matching degree is high, thereby avoiding the overall poor optical quality after closing the pieces, and at the same time avoiding the hole edge of the perforated inner glass and the non-perforated outer glass to easily form an opening, resulting in many bubbles after closing the pieces, resulting in a reduced yield rate.

In the following description, many specific details are set forth to facilitate a full understanding of the present application.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0043] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0044] Referring to FIG1 , a glass forming mold 100 is shown in an embodiment of the present application, which is used to alternately and continuously produce a hole-drilled inner glass and a non-hole-drilled outer glass. It should be noted that the hole-drilled inner glass refers to a glass sheet with an inner hole, and the inner hole can be a through hole that penetrates the thickness direction of the glass sheet or a blind hole that does not penetrate the thickness direction of the glass sheet. The hole-drilled inner glass and the non-hole-drilled outer glass can form a laminated glass after being assembled. When the laminated glass is installed on a vehicle for use, the hole-drilled inner glass is arranged toward the inner side of the vehicle.

[0045] The non-hole outer glass refers to a glass sheet without inner holes, that is, a glass sheet with a complete structure and uniform thickness. The inner glass with holes and the outer glass without holes are combined to form laminated glass. When the laminated glass is installed on a vehicle for use, the outer glass without holes is arranged toward the outside of the vehicle.

[0046] Please continue to refer to Figures 1 to Figure 4 Exemplarily, the glass forming mold 100 includes a male mold mechanism 10 and a female mold mechanism 20 .

[0047] The male mold mechanism 10 includes a first adsorption area 11 and a second adsorption area 12. The first adsorption area 11 and / or the second adsorption area 12 are used to fix the glass sheet entering the forming station 30 by vacuum adsorption.

[0048] The female mold mechanism 20 and the male mold mechanism 10 are arranged relative to each other along the height direction of the glass forming mold 100 and surround a forming station 30. The female mold mechanism 20 includes a first female mold component 21 and a second female mold component 22. Both the first female mold component 21 and the second female mold component 22 can move close to or away from the male mold mechanism 10. It is easy to understand that when the female mold mechanism 20 is away from the male mold mechanism 10, the forming station 30 is opened so that the original glass sheet enters the forming station 30 and the inner glass with holes and the outer glass without holes obtained by pressing are moved out of the forming station 30; when the female mold mechanism 20 is close to the male mold mechanism 10, the two form a mold, so that the original glass sheet in the forming station 30 can be pressed to obtain the inner glass with holes and the outer glass without holes.

[0049] It should be noted that the glass original sheet mentioned in the present application specifically refers to a glass substrate used for forming a holed inner sheet glass and a non-holed outer sheet glass, and its size is usually larger than the required holed inner sheet glass and non-holed outer sheet glass. When the punch mechanism 10 and the die mechanism 20 cooperate to close the mold and press, the holed inner sheet glass and the non-holed outer sheet glass of the required shape and size can be obtained based on the glass original sheet.

[0050] Among them, the first adsorption area 11 is set corresponding to the hole-digging part of the glass, the first die assembly 21 is set corresponding to the outer contour of the hole-digging part of the glass, the second adsorption area 12 is set corresponding to the non-hole-digging part of the glass, and the second die assembly 22 is set corresponding to the outer contour of the glass. The glass forming mold 100 has a first mold closing state and a second mold closing state. In the first mold closing state, the first adsorption area 11 and the second adsorption area 12 simultaneously adsorb the glass original sheet, and the second die assembly 22 is molded with the punch mechanism 10 to press the glass original sheet into an outer sheet of glass without holes. In the second mold closing state, the second adsorption area 12 adsorbs the glass original sheet, and the first die assembly 21 and the second die assembly 22 are molded with the punch mechanism 10 simultaneously to press the glass original sheet into an inner sheet of glass with holes.

[0051] In summary, the implementation of the technical solution of this embodiment will achieve the following beneficial effects: the glass forming mold 100 of this solution is used in the processing occasions of producing the inner glass with holes and the outer glass without holes constituting laminated glass; since the first adsorption area 11 is set corresponding to the hole-digging part of the glass, the first concave mold component 21 is set corresponding to the outer contour of the hole-digging part of the glass, the second adsorption area 12 is set corresponding to the non-hole-digging part of the glass, and the second concave mold component 22 is set corresponding to the outer contour of the glass, during processing, the glass original sheets heated to a molten state are transported by the conveying mechanism one by one into the forming station 30 of the glass forming mold 100, and when the current glass original sheet arrives at the forming station 30, in response to the instruction of the first mold closing state, the system controls The first adsorption area 11 and the second adsorption area 12 adsorb the glass sheet at the same time, and control the second concave mold assembly 22 and the convex mold mechanism 10 to close the mold so that the glass sheet can be pressed into an outer glass without holes, and then the outer glass without holes is moved out of the molding station 30 to vacate the molding station 30; thereafter, the next glass sheet heated to a molten state is conveyed into the molding station 30, and in response to the instruction of the second closing mold state, the system only controls the second adsorption area 12 to adsorb the glass sheet, and controls the first concave mold assembly 21 and the second concave mold assembly 22 to close the mold with the convex mold mechanism 10 at the same time, so that the glass sheet can be pressed into an inner glass with holes, and then the inner glass with holes is moved out of the molding station 30 to vacate the molding station 30.

[0052] By continuously repeating the above processing steps, the inner glass with a hole and the outer glass without a hole can be continuously and alternately produced with only one set of glass forming molds 100. On the one hand, the number of molds used is saved, and the manufacturing cost and the difficulty of mold management are reduced. On the other hand, the inner glass with a hole and the outer glass without a hole are both obtained by pressing with the same glass forming mold 100, so the shapes and curvatures of the two glass sheets after bending are consistent, and the matching degree is high, thereby avoiding poor overall optical quality after joining. At the same time, it also avoids the problem that the hole edge of the inner glass with a hole and the outer glass without a hole are easy to form an opening, resulting in many bubbles after joining, which leads to a reduced yield.

[0053] It should be noted that the order of pressing and producing the inner glass with holes and the outer glass without holes can be flexibly adjusted according to actual needs. That is to say, it can be produced in an alternating order of first producing the inner glass with holes and then the outer glass without holes, or it can be produced in an alternating order of first producing the outer glass without holes and then the inner glass with holes.

[0054] Please continue to refer to Figures 2 to Figure 3 In the present application, the male mold mechanism 10 is arranged above the female mold mechanism 20. On the basis of the above embodiment, the male mold mechanism 10 includes a male mold surface 10a, which is specifically the bottom surface of the male mold mechanism 10. The male mold surface 10a is directly opposite to the female mold mechanism 20. In the open mold state, the cavity between the male mold surface 10a and the female mold mechanism 20 is the forming station 30. The male mold surface 10a is provided with a first adsorption area 11 and a second adsorption area 12, and the second adsorption area 12 is arranged outside the periphery of the first adsorption area 11. For example, the first adsorption area 11 is located in the middle position of the second adsorption area 12, so that after the inner glass with a hole is obtained by pressing, the hole can be located in the middle position of the inner glass with a hole, which makes it easier to ensure the structural strength of the inner glass with a hole.

[0055] Of course, in other optional embodiments, the relative position relationship between the first adsorption area 11 and the second adsorption area 12 may also be other designs, such as the first adsorption area 11 being located at the top corner or side of the second adsorption area 12, etc., which can be selected according to actual needs.

[0056] Among them, the outer contours of the second adsorption area 12 and the second die assembly 22 are compatible with the outer contours of the inner glass with holes and the outer glass without holes, and the outer contours of the first adsorption area 11 and the first die assembly 21 are compatible with the hole shape of the hole of the inner glass with holes. In this way, when the first adsorption area 11 and the second adsorption area 12 simultaneously adsorb and fix the original glass sheet, and only the second die assembly 22 moves upward and closes the mold with the male mold mechanism 10, only the outer contour part of the required outer glass without holes is pressed, so after the pressing is completed, the outer glass without holes formed by reducing the material of the original glass sheet can be obtained, and the outer glass without holes has the required profile, curvature, size, etc. Alternatively, when the second adsorption area 12 adsorbs and fixes the original glass piece, and the first concave mold assembly 21 and the second concave mold assembly 22 simultaneously rise and move to close the mold with the punch mechanism 10, the second concave mold assembly 22 simultaneously presses out the outer contour of the inner glass with a hole, and at the same time, the first concave mold assembly 21 presses and removes excess material at the corresponding hole-digging position in the middle of the original glass piece to form a hole-digging structure. After that, when the concave mold mechanism 20 and the punch mechanism 10 are opened and separated, the inner glass with a hole formed after the original glass piece is reduced in material can be obtained.

[0057] Please continue to refer to Figures 2 to Figure 3 In another embodiment, the male mold mechanism 10 includes an outer cavity 13 and an inner cavity 14, the outer cavity 13 is arranged around the outer periphery of the inner cavity 14, and the male mold surface 10a is connected to the same side of the outer cavity 13 and the inner cavity 14 facing the female mold mechanism 20. The male mold surface 10a is formed by assembling the outer cavity 13 and the inner cavity 14, and then the glass original sheet can be pressed into a holed inner sheet glass or a non-holed outer sheet glass by the male mold surface 10a and the female mold mechanism 20.

[0058] In order to generate vacuum suction force in the first adsorption area 11 and the second adsorption area 12 to adsorb and fix the original glass sheet, in an optional embodiment, the glass forming mold 100 further includes a vacuum tube 40, which is arranged on the male mold mechanism 10, and one end of the vacuum tube 40 is connected to the first adsorption area 11 and the second adsorption area 12, and the other end of the vacuum tube 40 is used to communicate with a vacuum generator. During processing, the vacuum generator sucks air in the first adsorption area 11 and / or the second adsorption area 12, so that the first adsorption area 11 and / or the second adsorption area 12 can generate vacuum suction force.

[0059] In addition, compared with the use of mechanical clamps and other methods to fix the glass sheet entering the forming station 30, the vacuum adsorption method will not cause deformation of the molten glass sheet, which helps to ensure the forming quality of the inner glass with holes and the outer glass without holes obtained by pressing.

[0060] Please continue reading Figure 3On the basis of any of the above embodiments, the first adsorption area 11 and the second adsorption area 12 are both provided with a plurality of vacuum adsorption holes 10b arranged at even intervals. When the first adsorption area 11 and / or the second adsorption area 12 adsorb and fix the original glass sheet, the adsorption force applied by each vacuum adsorption hole 10b to the original glass sheet is evenly distributed and of the same magnitude, thereby helping to ensure the appearance quality of the inner glass sheet with holes and the outer glass sheet without holes after press forming.

[0061] It should be noted that the parameters such as the shape and size of the vacuum adsorption holes 10b and the spacing distance between the vacuum adsorption holes 10b can be flexibly designed according to actual needs and are not particularly limited here.

[0062] Please continue to refer to Figure 2. In order to improve the connection strength between the outer cavity 13 and the inner cavity 14 so that the punch mechanism 10 can obtain better overall structural performance, in one embodiment, the punch mechanism 10 also includes a connecting plate 15, and the outer cavity 13 is connected and fixed to the inner cavity 14 through the connecting plate 15.

[0063] Optionally, four connecting plates 15 are provided, and the connecting plates 15 and the outer cavity 13 and the inner cavity 14 are connected in a manner that is not limited to at least one of welding, bonding, screwing, and clamping.

[0064] Please continue reading Figure 4 In addition, based on any of the above embodiments, the first die assembly 21 includes a first die 211 and a first lifting drive unit 212, the first lifting drive unit 212 is connected to the first die 211, and is used to drive the first die 211 to move closer to or away from the punch mechanism 10. Therefore, by outputting a lifting drive force to the first die 211 through the first lifting drive unit 212, the first die 211 can be driven to rise to close the die with the punch mechanism 10 or to fall to separate from the punch mechanism 10. Similarly, the second die assembly 22 includes a second die 221 and a second lifting drive unit 222, the second lifting drive unit 222 is connected to the second die 221, and is used to drive the second die 221 to move closer to or away from the punch mechanism 10. By outputting a lifting driving force to the second female mold 221 through the second lifting driving unit 222, the second female mold 221 can be driven to rise to engage with the male mold mechanism 10 or to descend to separate from the male mold mechanism 10, thereby facilitating the pressing and forming of the inner glass with holes and the outer glass without holes, so that the inner glass with holes and the outer glass without holes can be easily moved out of the forming station 30.

[0065] Specifically, in an optional embodiment, the first lifting drive unit 212 and the second lifting drive unit 222 both include a support and a driving cylinder, the cylinder seat of the driving cylinder is arranged on the support, and the piston rod of the driving cylinder is connected to the first concave mold 211 and the second concave mold 221. By directly outputting the telescopic linear power by the driving cylinder, the first concave mold 211 and the second concave mold 221 can be driven to move up and down, so that the concave mold mechanism 20 and the convex mold mechanism 10 can be matched to close or open the mold. The first lifting drive unit 212 and the second lifting drive unit 222 of this embodiment have simple structures and low implementation costs.

[0066] Alternatively, in another optional embodiment, the first lifting drive unit 212 and the second lifting drive unit 222 both include a support, a motor, a driving rod and a transmission block, the motor is arranged on the support, the driving rod is connected to the driving shaft of the motor, the transmission block is movably connected to the driving rod through a threaded pair, and the transmission block is connected to the first die 211 and the second die 221. During processing, the motor drives the driving rod to rotate, so that the transmission block can be lifted and moved on the driving rod with the help of the threaded pair, so as to drive the first die 211 and the second die 221 to be lifted and moved, so as to meet the needs of the glass forming mold 100 for pressing glass, and compared with the above-mentioned embodiment using a driving cylinder, when the die mechanism 20 and the punch mechanism 10 are combined for pressing, the die mechanism 20 will be subjected to a reaction force and there is a hidden danger of retreat, and with the help of the self-locking characteristics of the threaded pair, the position accuracy of the die mechanism 20 can be ensured, that is, the die mechanism 20 can be prevented from retreating, which helps to ensure the shape and size accuracy of the inner glass with holes and the outer glass without holes obtained by pressing.

[0067] In addition, in order to ensure the position accuracy of the glass sheet when it is fed into the forming station 30 , in one embodiment, the glass forming mold 100 further includes a position sensor, which is disposed in the forming station 30 .

[0068] Please continue reading Figure 5 In another aspect of the present application, a forming method for processing a hole-drilled inner glass and a hole-free outer glass using the above glass forming mold 100 is provided, which comprises the following steps:

[0069] S10: The glass sheet heated to a molten state is transported to the forming station 30. In response to the first mold closing state, the first adsorption area 11 and the second adsorption area 12 are controlled to simultaneously adsorb the glass sheet.
