Description

Technical Field

[0001] This utility model relates to the field of tempered glass production technology, specifically to an impact-resistant tempered glass preparation mold. Background Technology

[0002] Impact-resistant tempered glass is a specially treated type of glass. Compressive stress is created on the glass surface through physical or chemical methods, which first counteracts the surface stress when subjected to external forces, thereby improving its load-bearing capacity and impact resistance. Because tempered glass is designed to meet various application requirements, it needs to be bent using molds. These molds shape the tempered glass into a specific curvature during processing to meet the needs of curved glass surfaces. The bending process for tempered glass using molds is as follows: First, the tempered glass is heated using a heating device. Then, the heated tempered glass is conveyed into the mold. The upper and lower molds are then closed to compress the tempered glass, causing it to bend according to the shape of the mold cavity. Finally, the tempered glass cools and solidifies naturally within the mold cavity.

[0003] CN221319776U discloses a curved tempered glass forming mold, including a base. A lower mold and a support plate are arranged on the upper part of the base, with the lower mold located inside the support plate. A cylinder is arranged at the top of the support plate, and an upper mold is arranged at the bottom of the cylinder. A groove is formed at the bottom of the upper mold, and a pressure plate is slidably arranged inside the groove, with the bottom end of the pressure plate extending through the groove. Connecting frames are arranged on both the left and right sides of the upper part of the upper mold. A toothed plate is movably arranged within the connecting frames, with the bottom end of the toothed plate extending into the groove and connecting to the top of the pressure plate. A rotating rod is rotatably arranged between the two connecting frames, and multiple gears are arranged on the rotating rod. This invention facilitates the adjustment of the pressure plate's position during use, and allows for more precise adjustment, thus ensuring the glass shaping effect.

[0004] While the existing technology CN221319776U has many advantages in use, it still has the following problems: it lacks an ejection structure for the tempered glass molded parts inside the mold cavity. Since the surface curvature of the tempered glass is matched with the curvature of the mold groove after it is bent and formed inside the mold, it is inconvenient for the staff to remove the tempered glass, which affects the removal efficiency of the tempered glass after molding. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides an impact-resistant tempered glass preparation mold.

[0006] The technical solution adopted by this utility model to solve its technical problem is an impact-resistant tempered glass preparation mold, including a lower mold base, an upper mold base, a liquid storage tube, and a support tube. The upper outer wall of the lower mold base has a mold cavity, and the inner wall of the mold cavity has a rectangular array of receiving cavities. The receiving cavities are provided with a support tube. The upper outer wall of the support tube is screwed to a sealing plate. A support rod is movably installed inside the sealing plate. The upper outer wall of the support rod is screwed to a pusher column. The upper mold base is provided at the upper end of the lower mold base. Liquid storage tubes are provided on both outer walls of the lower mold base. Movable rods are movably installed inside the liquid storage tubes.

[0007] By adopting the above technical solution, the workers first lay a silicone rubber-coated fiber cloth at the lower end of the mold cavity to separate the mold cavity from the heated tempered glass plate, preventing the tempered glass from sticking to the inner wall of the mold cavity and ensuring the flatness and smoothness of the inner wall of the mold cavity. The workers place the heated glass plate inside the mold cavity, and the external hydraulic press drives the upper mold seat to move vertically through the connecting seat until the mold head enters the mold cavity, thereby extruding and shaping the glass plate inside the mold cavity. This ensures the precision of the fit between the glass plate and the inner wall of the mold cavity, ensures the shape accuracy of the glass plate after it is formed through the mold cavity, and guarantees the quality of the tempered glass preparation. After the upper mold seat is driven upward, the assembly plate can pull the movable rod and the sealing plate to move synchronously. The sealing plate pushes the hydraulic oil inside the reservoir tube to be discharged through the delivery pipe until the hydraulic oil is diverted into each support tube. According to the amount of oil entering the support tube, the piston plate, support rod and push column can be pushed upward, thereby pushing out the shaped glass plate inside the mold cavity, making it easier for the workers to remove the glass plate and improving the glass plate removal efficiency.

[0008] Specifically, a mold head is screwed to the lower end of the upper mold base. The size of the mold head is adapted to the size of the mold cavity, and the mold head is located inside the mold cavity. A connecting seat is welded to the upper outer wall of the upper mold base.

[0009] By adopting the above technical solution, the size of the mold head and the mold cavity are precisely matched, ensuring that the glass is subjected to uniform force on the edges and inside during the pressing process, thus guaranteeing the forming quality of tempered glass. The upper mold base can be connected to an external hydraulic press through the connecting seat, thereby allowing the upper mold base to be adjusted in its position.

[0010] Specifically, a sealing plate is provided at the lower end of the movable rod, and the sealing plate is in contact with the inner wall of the liquid storage tube. Assembly plates are screwed to both outer walls of the upper mold base, and the assembly plates are screwed to the upper end of the movable rod.

[0011] By adopting the above technical solution, a sealing ring is bonded to the outside of the sealing plate, which can ensure the sealing between the sealing plate and the inner wall of the liquid storage tube, and ensure the stability of the push or pull of hydraulic oil inside the liquid storage tube. The assembly plate ensures that the movable rod can follow the movement of the upper mold base, and ensures that the movement of the push column can be driven by the movement of the upper mold base.

[0012] Specifically, the lower outer wall of the support tube is equipped with a circular array of connectors, and the support tube is connected to the lower outer wall of the lower mold base by screws through the connectors.

[0013] By adopting the above technical solution, the connector ensures the connection strength between the support tube and the lower mold base, thereby stabilizing the position of the support tube inside the receiving cavity.

[0014] Specifically, a piston plate is screwed to the outer wall of the lower end of the support rod. The piston plate is located inside the support tube, and the outer wall of the piston plate is in contact with the inner wall of the support tube.

[0015] By adopting the above technical solution, when hydraulic oil enters the support pipe through the diversion pipe, the piston plate can push the support rod and the pusher column to move upward. The smoothness of hydraulic pressure is used to achieve uniform ejection of the pusher column, thereby pushing the tempered glass inside the mold cavity out.

[0016] Specifically, the upper end face of the pusher post adopts an arc shape design, and the arc of the upper end face of the pusher post is adapted to the arc of the inner wall of the mold cavity.

[0017] By adopting the above technical solution, the pusher column can shield the inside of the receiving cavity when the tempered glass is formed inside the mold cavity, ensuring the overall smoothness of the inner wall of the mold cavity. In conjunction with the silicone rubber coated fiber cloth, it avoids the gap between the pusher column and the receiving cavity from affecting the tempered glass, thus ensuring the forming accuracy of the tempered glass.

[0018] Specifically, a diversion pipe is welded to the lower outer wall of the support pipe, and an infusion pipeline is welded to one side of the upper outer wall of the storage pipe, with a flange connecting the diversion pipe and the infusion pipeline.

[0019] By adopting the above technical solution, the flange connection ensures the smooth flow of hydraulic oil between the diversion pipe and the delivery pipe, and the hydraulic oil is discharged or drawn back according to the relative position of the sealing plate inside the storage pipe. The diversion pipe enables the synchronous action of multiple sets of support rods, ensuring the consistency of the push column when it is pushed out.

[0020] Specifically, the outer walls on both sides of the liquid storage tube are equipped with fixing brackets, and the fixing brackets are screwed to the outer wall of the lower mold base.

[0021] By adopting the above technical solution, the fixing frame securely installs the liquid storage pipe on the lower mold base, ensuring the stability of hydraulic oil pressure transmission.

[0022] The beneficial effects of this utility model are: The impact-resistant tempered glass preparation mold of this utility model can push the piston plate, support rod and push column upward to push out the glass plate after it has been shaped inside the mold cavity, making it easier for workers to take out the glass plate and improving the glass plate removal efficiency.

[0023] The present invention discloses an impact-resistant tempered glass preparation mold in which the mold head enters the mold cavity and extrudes and shapes the glass plate inside the mold cavity, ensuring the precision of the fit between the glass plate and the inner wall of the mold cavity, ensuring the shape accuracy of the glass plate after it passes through the mold cavity, and guaranteeing the quality of tempered glass preparation.

Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the present invention provides an impact-resistant tempered glass preparation mold, comprising a lower mold base 1, an upper mold base 2, a liquid storage tube 3, and a support tube 4. The upper outer wall of the lower mold base 1 has a mold cavity 11, and the inner wall of the mold cavity 11 has a rectangular array of receiving cavities 12. The receiving cavity 12 is provided with a support tube 4, and the upper outer wall of the support tube 4 is screwed to a sealing plate 43. A support rod 44 is movably installed inside the sealing plate 43, and a pusher column 45 is screwed to the upper outer wall of the support rod 44. The upper mold base 2 is provided at the upper end of the lower mold base 1, and liquid storage tubes 3 are provided on both outer walls of the lower mold base 1. Movable rods 32 are movably installed inside the liquid storage tubes 3.

[0029] During use, the operator first lays a silicone rubber-coated fiber cloth at the lower end of the mold cavity 11 to separate the mold cavity 11 from the heated tempered glass plate, preventing the tempered glass from sticking to the inner wall of the mold cavity 11 and ensuring the flatness and smoothness of the inner wall of the mold cavity 11. The operator then places the heated glass plate inside the mold cavity 11. An external hydraulic press drives the upper mold base 2 to move vertically through the connecting seat 22 until the mold head 23 enters the mold cavity 11, thereby extruding and molding the glass plate inside the mold cavity 11. This ensures the precision of the fit between the glass plate and the inner wall of the mold cavity 11. The shape accuracy of the glass plate after being formed in the mold cavity 11 is ensured to guarantee the quality of tempered glass preparation. After the upper mold base 2 is driven to move upward, the assembly plate 21 can pull the movable rod 32 and the sealing plate to move synchronously. The sealing plate pushes the hydraulic oil inside the liquid storage pipe 3 to be discharged through the liquid delivery pipe until the hydraulic oil is diverted to the inside of each support pipe 4. According to the amount of oil entering the support pipe 4, the piston plate 46, the support rod 44 and the pusher column 45 can be pushed upward, thereby pushing out the glass plate after it has been shaped inside the mold cavity 11, making it easier for the staff to take out the glass plate and improving the efficiency of glass plate removal.

[0030] For extrusion molding, for example, such as Figure 2 As shown, a mold head 23 is screwed to the lower end of the upper mold base 2. The size of the mold head 23 is adapted to the size of the mold cavity 11, and the mold head 23 is located inside the mold cavity 11. A connecting seat 22 is welded to the upper outer wall of the upper mold base 2.

[0031] When in use, the size of the mold head 23 is precisely matched with the mold cavity 11 to ensure that the glass is subjected to uniform force on the edges and inside during the pressing process, thus ensuring the forming quality of the tempered glass. The upper mold base 2 can be connected to an external hydraulic press through the connecting seat 22, thereby adjusting the usage position of the upper mold base 2.

[0032] To drive the flow of hydraulic oil, for example, such as Figure 4 As shown, a sealing plate is provided at the lower end of the movable rod 32, and the sealing plate is in contact with the inner wall of the liquid storage tube 3. Assembly plates 21 are screwed to both outer walls of the upper mold base 2, and the assembly plates 21 are screwed to the upper end of the movable rod 32.

[0033] During use, a sealing ring is bonded to the outside of the sealing plate to ensure the sealing between the sealing plate and the inner wall of the liquid storage pipe 3, and to ensure the stability of the push or pull of hydraulic oil inside the liquid storage pipe 3. The assembly plate 21 ensures that the movable rod 32 can move with the upper mold base 2, and ensures that the movement of the push column 45 can be driven by the movement of the upper mold base 2. The amount of hydraulic oil inside a single liquid outlet pipe 3 corresponds to the capacity of hydraulic oil to be received inside the two support pipes 4.

[0034] To maintain the usage location, for example, such as Figure 5 As shown, a circular array of connectors 41 are installed on the lower outer wall of the support tube 4, and the support tube 4 is connected to the lower outer wall of the lower mold base 1 by screws through the connectors 41.

[0035] During use, the connector 41 ensures the connection strength between the support tube 4 and the lower mold base 1, thereby stabilizing the position of the support tube 4 inside the receiving cavity 12.

[0036] For example, to enable coordinated movement, such as... Figure 5 As shown, a piston plate 46 is screwed to the lower outer wall of the support rod 44. The piston plate 46 is located inside the support tube 4, and the outer wall of the piston plate 46 is in contact with the inner wall of the support tube 4.

[0037] When in use, when hydraulic oil enters the support pipe 4 through the diverter pipe 42, the piston plate 46 can push the support rod 44 and the pusher column 45 to move upward. The smoothness of hydraulic pressure is used to achieve uniform ejection of the pusher column 45, thereby pushing the tempered glass inside the mold cavity 11 out.

[0038] To maintain flatness, for example, such as Figure 2 As shown, the upper end face of the pusher post 45 adopts an arc shape design, and the arc of the upper end face of the pusher post 45 is adapted to the arc of the inner wall of the mold cavity 11.

[0039] When in use, the pusher column 45 can shield the inside of the receiving cavity 12 when the tempered glass is formed inside the mold cavity 11, ensuring the smoothness of the inner wall of the mold cavity 11. In conjunction with the silicone rubber coated fiber cloth, it can prevent the gap between the pusher column 45 and the receiving cavity 12 from affecting the tempered glass and ensure the forming accuracy of the tempered glass.

[0040] To control the flow trajectory of hydraulic oil, for example, such as Figure 3 As shown, a diversion pipe 42 is welded to the lower outer wall of the support pipe 4, and an infusion line 31 is welded to one side of the upper outer wall of the storage pipe 3. The diversion pipe 42 and the infusion line 31 are connected by a flange.

[0041] During use, the flange connection ensures the smooth flow of hydraulic oil between the diversion pipe 42 and the delivery pipe 31, and discharges or draws back the hydraulic oil according to the relative position of the sealing plate inside the storage pipe 3. The diversion pipe 42 enables the synchronous action of multiple sets of support rods 44, ensuring the consistency of the push column 45 when it is pushed out.

[0042] To maintain the usage location, for example, such as Figure 4 As shown, a fixing bracket 33 is installed on both sides of the outer wall of the liquid storage tube 3, and the fixing bracket 33 is screwed to the outer wall of the lower mold base 1.

[0043] During use, the fixing bracket 33 securely installs the liquid storage pipe 3 on the lower mold base 1 to ensure the stability of hydraulic oil pressure transmission.

[0044] In use, a silicone rubber coated fiber cloth is laid at the bottom of the mold cavity 11 as an isolation layer to prevent the glass from sticking to the mold and to improve the flatness of the molding surface. The heated tempered glass is transported into the mold cavity 11. The hydraulic press drives the upper mold base 2 to descend vertically through the connecting seat 22. The mold head 23 gradually enters the mold cavity 11. The softened glass adheres to the inner wall of the mold cavity 11 under the pressure of the mold head 23, forming a preset arc. The arc design of the upper end face of the push column 45 is consistent with the arc of the mold cavity 11. During the molding process, it fills the receiving cavity 12. After molding, the glass cools naturally in the mold. The hydraulic press drives the upper mold base 2 to rise, and the assembly plate 21 pulls the movable rod 32 and the sealing plate in sync. The sealing plate pushes the hydraulic oil in the reservoir pipe 3 to be discharged through the infusion pipe 31. The hydraulic oil enters each support pipe 4 through the diversion pipe 42. The hydraulic oil pushes the piston plate 46 to rise, driving the support rod 44 and the pusher column 45 to be pushed out in sync. The pusher column 45 evenly contacts the bottom surface of the glass, and smoothly pushes the tempered glass out of the mold cavity 11. When the upper mold base 2 descends, the movable rod 32 pulls the sealing plate, and the hydraulic oil is drawn back to the reservoir pipe 3 through the liquid supply line 31. The pusher column 45 falls back into the receiving cavity 12, so that the heated tempered glass can be squeezed and shaped through the mold head and the mold cavity 11.

All components in this utility model are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
