Description

Technical Field

[0001] This utility model belongs to the field of tempered glass, and in particular relates to a molding die for curved tempered glass. Background Technology

[0002] To improve the strength of glass, chemical or physical methods are typically used to create compressive stress on the glass surface. When the glass is subjected to external force, this surface stress is first offset, thereby improving its load-bearing capacity and enhancing its resistance to wind pressure, temperature changes, and impacts. This type of glass is called tempered glass. Curved tempered glass is a special type of tempered glass with a unique geometric shape and high-quality surface treatment. It has advantages such as high strength, wear resistance, safety, and aesthetics. Curved tempered glass is usually formed by hot bending, which requires the use of forming molds.

[0003] Comparing with Chinese Patent No. CN221319776U, a curved tempered glass forming mold is disclosed, including a base, a lower mold and a support plate are provided on the upper part of the base, and the lower mold is located inside the support plate. A cylinder is provided at the top of the support plate, and an upper mold is provided at the bottom of the cylinder. A groove is opened 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 provided on the left and right sides of the upper part of the upper mold. A toothed plate is movably arranged in the connecting frame, 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 provided on the rotating rod, with the gears meshing with the toothed plate. A connecting shell is provided on one side of one of the connecting frames, and a driving mechanism is provided inside the connecting shell.

[0004] In the aforementioned patent, during the hot bending process of glass, the glass needs to be bent downwards to fit the mold cavity. This causes relative sliding between the glass and the mold cavity surface, generating friction and reducing the quality of the formed glass. Therefore, a new type of equipment needs to be designed.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 A curved tempered glass forming mold includes a support device for supporting the forming and lifting the mold closing, and a limiting device installed in the support device for adhering to and following the deformation of the glass from the upper and lower sides. The limiting device is equipped with an extrusion device for pressing down on the bent glass and adjusting the curvature.

[0026] In this embodiment: the support device includes a support frame 101, a lifting assembly is installed on the top of the support frame 101, an upper mold base 104 is provided below the lifting assembly, an overhead frame 106 is provided below the upper mold base 104, and a lower mold base 105 is provided on the overhead frame 106. The lifting assembly includes a lifting cylinder 102, a lifting frame 103 is installed at the bottom of the lifting cylinder 102, and the lifting frame 103 is slidably connected to the support frame 101. The support frame 101 supports the extension of the lifting cylinder 102 to move the lifting frame 103 downward, thereby causing the upper mold base 104 to move toward the lower mold base 105 supported by the overhead frame 106 to perform mold closing.

[0027] In this embodiment: the limiting device includes a lower limiting frame 201, an upper limiting frame 202 is provided above the lower limiting frame 201, a clamping deformation component is provided at the top of the lower limiting frame 201 and the bottom of the upper limiting frame 202, four horizontal sliding grooves 206 are evenly provided at the four corners of the clamping deformation component, and two vertical sliding grooves 207 are symmetrically provided at the middle position of the lower clamping deformation component. The clamping deformation component includes an elastic clamping plate 203, four horizontal sliding pins 204 are evenly provided at the four corners of the elastic clamping plate 203, and two vertical sliding pins 205 are symmetrically provided on both sides of the middle position of the elastic clamping plate 203. The horizontal sliding pins 204 are slidably connected to the horizontal sliding grooves 206. The vertical sliding pin 205 is slidably connected to the vertical sliding groove 207. The softened tempered glass is placed on the elastic clamping plate 203 below. Then the mold is closed, so that the upper mold base 104 drives the elastic clamping plate 203 in the upper limit frame 202 to press down against the tempered glass and clamp it. Then the extrusion device presses down on the elastic clamping plate 203, so that it causes the tempered glass in the middle to deform. During this process, the horizontal sliding pins 204 at the four corners of the elastic clamping plate 203 slide along the horizontal sliding groove 206, and the vertical sliding pin 205 in the middle slides along the vertical sliding groove 207 to limit the deformation of the elastic clamping plate 203 and make the deformation on both sides of the elastic clamping plate 203 consistent.

[0028] In this embodiment: the extrusion device includes a fixed plate 301, with two downward pressing cylinders 302 symmetrically arranged on both sides of the fixed plate 301. Seven downward pressing components are evenly installed on the fixed plate 301, and an upper lifting component is arranged below the downward pressing components. The downward pressing components include downward pressing rollers 304, with two adjusting cylinders 303 symmetrically installed on the downward pressing rollers 304. The upper lifting component includes a support roller 305, with two limiting rods 306 symmetrically arranged on both sides below the support rollers 305. Springs 307 are installed on the outside of the limiting rods 306, so that the fixed plate 301 supports the adjusting cylinders 303 to extend and retract, driving the downward pressing cylinders 302 to move up and down. This adjusts the curvature of the forming surface formed by the seven lower pressure rollers 304. Then, the lifting frame 103 supports the extension of the lower pressure cylinder 302, which drives all the lower pressure rollers 304 to move downward through the fixed plate 301. This causes the two elastic clamping plates 203 to deform under the support of the upper limit frame 202 and the lower limit frame 201, and causes the tempered glass in the middle to deform. During this process, the lower elastic clamping plate 203 will press down the support roller 305, causing the support roller 305 to press down the spring 307 along the limit rod 306, thereby providing support for the deformation of the elastic clamping plate 203 from the bottom and improving the stability of the forming.

[0029] Working principle: The lower mold base 105 is fixed on the overhead frame 106 to provide support for the lower limit frame 201, and the upper mold base 104 is fixed below the lifting frame 103 to provide support for the upper limit frame 202. In use, the fixed plate 301 supports the extension and retraction of the adjusting cylinder 303, which drives the pressing cylinder 302 to move up and down, thereby adjusting the curvature of the forming surface formed by the seven pressing rollers 304. After adjusting to the appropriate curvature, the softened tempered glass is placed on the elastic clamping plate 203 below. Then, the support frame 101 supports the extension of the lifting cylinder 102, which drives the lifting frame 103 to move downward. This causes the upper mold base 104 to drive the elastic clamping plate 203 in the upper limit frame 202 to press down against the tempered glass. Then, the lifting frame 103 supports the pressing cylinder. The extension of 302 drives all the downward pressure rollers 304 to move downward through the fixed plate 301, thereby squeezing the two elastic clamping plates 203 to deform under the support of the upper limit frame 202 and the lower limit frame 201, and causing the tempered glass in the middle to deform. During this process, the horizontal sliding pins 204 at the four corners of the elastic clamping plate 203 slide along the horizontal sliding groove 206, and the vertical sliding pin 205 in the middle slides along the vertical sliding groove 207, limiting the deformation of the elastic clamping plate 203 and making the deformation on both sides of the elastic clamping plate 203 consistent. At the same time, the lower elastic clamping plate 203 will press down the support roller 305, causing the support roller 305 to press down the spring 307 along the limit rod 306, thereby providing support for the deformation of the elastic clamping plate 203 from the bottom and improving the stability of the molding.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
