Description

Technical Field

[0001] The present invention relates to the technical field of glass processing, in particular to a hot bending die forming device for glass processing. Background Art

[0002] Glass hot bending and compression molding technology involves heating and softening the glass material and then applying pressure to a mold. It is widely used in the automotive, architectural, home appliance, and consumer electronics sectors to produce glass products with complex geometries, such as curved glass, 3D cover panels, and vehicle windows. With increasing demand for glass with lightweight, high-strength, high-transmittance, and complex curved designs in industries like smart devices and new energy vehicles, traditional hot bending processes face significant challenges in terms of efficiency, precision, and cost control.

[0003] A search revealed a Chinese patent application with publication number CN214270669U, which discloses a mold for a 3D glass bending machine and a 3D glass bending machine. The device comprises an upper mold, a middle mold, and a lower mold, wherein the bottom of the upper mold cooperates with the top of the middle mold to form a first cavity, and the bottom of the middle mold cooperates with the top of the lower mold to form a second cavity. This simple mold structure allows for simultaneous bending of two sheets of glass. However, the following problems still exist: 1. After the glass is hot-bent, it needs to be cooled before it can be removed. However, the device needs to cool naturally after the glass is hot-bent. This process takes a long time, which affects the efficiency of the glass hot-bending process. 2. After the glass is hot-bent, the bent glass is tightly attached to the mold surface. When removing it, you need to manually hold the edge of the glass and lift it up before you can remove it. During the lifting process, the glass is easy to slip, and glass is fragile, so it is easy to break, causing losses. Summary of the Invention

Then, the required thickness positioning block 1003 is placed in the square groove 1001, and then the glass plate to be hot-bent is placed in the middle position of the supporting mold 801 and aligned. Then, the supporting mold 801 is heated by the heating rack 803. 801 , the glass is heated and softened, and the heating frame 803 and the heating wire 603 are turned on at the same time. When the softened glass is fitted with the supporting mold 801, the heating frame 803 and the heating wire 603 can be closed. After the glass is softened, the cylinder 401 is started to continue to extend until the pressing mold 601 contacts the thickness positioning block 1003 to meet the glass thickness requirement. After pressing for a period of time, the cylinder 401 is started to retract one end upward to ensure that the spring 905 is in a stressed state. The upper and lower sides of the glass can be heated synchronously by the provided heating frame 803 and the heating wire 603, so that the glass softens faster, thereby accelerating the efficiency of the glass hot bending molding. By means of the provided screws 505 and 705,When the mold needs to be replaced, the pressing mold 601 and the supporting mold 801 can be removed and replaced, so that the mold can be replaced to adapt to different molds to press out different shapes of glass, thereby increasing the adaptability of the device.

[0025] In order to quickly and stably cool the glass plate, the cooling component of the present invention includes a water pipe rack 804 embedded in the top wall of the supporting mold 801, and both ends of the water pipe rack 804 pass through the bottom inner wall of the supporting mold 801 and then extend out. The two ends of the water pipe rack 804 are respectively provided with an inlet pipe 805 and a liquid outlet pipe 806 for water inlet and outlet. The supporting mold 801 is provided with two symmetrical groups of thickness positioning components 10 for positioning the thickness of the glass, and each group is symmetrical. When the glass plate needs to be cooled, warm water is continuously introduced into the water pipe rack 804 through the inlet pipe 805 to cool the supporting mold 801 and the glass plate thereon. After the thickness is finalized, warm water can be introduced through the cooling component to transfer heat and cool the glass, thereby avoiding the risk of self-explosion when cold water is directly used and cooling the glass too quickly.

[0026] The supporting mold 801 is made of graphite.

[0027] To facilitate the removal of the glass plate, in the present invention, the lifting assembly 9 includes two fixed blocks 901 fixedly connected to one side of the connecting frame 402 by bolts, the lower surfaces of the two fixed blocks 901 are fixedly connected to the elliptical rod 902 by bolts, the bottom ends of the two elliptical rods 902 are fixedly connected to the limiting block 903 by bolts, and a slide plate 904 is slidably connected to the elliptical rod 902. A spring 905 is welded between the upper surface of the slide plate 904 and the lower surface of the fixed block 901. One side of the upper surface of the supporting mold 801 is provided with two embedding grooves 906 used in conjunction with the slide plate 904, and the upper surface of the workbench 1 is provided with two avoidance openings 907 for avoiding the elliptical rod 902. When the glass plate is hot-bending, the starting cylinder 401 is first extended to synchronize the connecting frame 402 and the upper mold assembly 6 thereon. When the sliding plate 904 is pressed against the bottom of the glass plate 402, the sliding plate 904 is pressed against the bottom of the glass plate 402, and the sliding plate 904 is pressed against the bottom of the glass plate 402.

[0028] To prevent the pressing mold 601 from being over-pressed, the thickness positioning component 10 includes a plurality of square grooves 1001 provided on the supporting mold 801, a square groove 1002 is provided on the bottom inner wall of the square groove 1001, a magnetic block 1005 is bonded to the bottom inner wall of the square groove 1002, a thickness positioning block 1003 is slidably connected in the square groove 1001, and a magnetic block 1004 used in conjunction with the magnetic block 1005 is bonded to the lower surface of the thickness positioning block 1003. Before placing the glass plate on the supporting mold 801, the required thickness positioning block 1003 is first placed in the square groove 1001. The thickness positioning component 10 can effectively prevent the upper mold assembly 6 from being over-pressed, thereby preventing errors in the thickness of the formed glass.

[0029] The heating wire 603 and the heating frame 803 are both powered on, and the liquid inlet pipe 805 and the liquid outlet pipe 806 are both connected to the external water pipe.

[0030] After the glass is hot-bent, subsequent steps are required to trim the glass.

[0031] The present invention is divided into the following steps when used: S1: When hot bending a glass sheet, the starting cylinder 401 is first extended to cause the connecting frame 402 and the upper mold assembly 6 thereon to move downward synchronously. During the downward movement of the connecting frame 402, the elliptical rod 902 on one side thereof is driven to move downward, causing the slide 904 thereon to move downward synchronously. When the slide 904 is embedded in the embedding groove 906, it continues to move downward until the spring 905 is compressed, and the cylinder 401 is stopped. S2: Then, the required thickness positioning block 1003 is placed into the square groove 1001, and the glass plate to be bent is placed in the middle position of the carrier mold 801 and aligned. Then, the carrier mold 801 is heated by the heating rack 803, and the heating wire 603 is turned on to accelerate the softening of the glass. The glass is heated and softened by heat conduction. After the softened glass is attached to the carrier mold 801, the heating rack 803 and the heating wire 603 are turned off. S3: After the glass is softened, the cylinder 401 is started to continue to extend until the pressing mold 601 contacts the thickness positioning block 1003 to meet the glass thickness requirement. After pressing for a period of time, the cylinder 401 is started to retract one end upward to ensure that the spring 905 is in a stressed state. Then, warm water is continuously introduced into the water pipe rack 804 through the liquid inlet pipe 805 to cool the supporting mold 801 and the glass plate thereon. S4: After the glass plate has finished cooling down, the cylinder 401 is started to shrink. During the shrinking process, the connecting frame 402 drives the elliptical rod 902 to move upward. When the limit block 903 at the bottom end of the elliptical rod 902 contacts the slide 904, the slide 904 moves upward to lift one side of the glass plate, and the staff can remove the glass plate.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described.
