Description

Technical Field

[0002] Hot-bent glass is curved glass that is made by heating and softening high-quality glass, forming it in a mold, and then annealing it to meet the high-quality requirements of modern architecture. It has a beautiful style and smooth lines. It breaks through the singularity of flat glass and is more flexible and diverse in use. It is suitable for special requirements of different shapes such as fish tanks, dining tables, balconies, mobile phone counters, cosmetic counters, hot-bent TV cabinets, doors, windows, ceilings, curtain walls, etc. It can produce various composite hot-bent glass products such as hollow and laminated ones, and can be customized according to customers' requirements. A graphite mold is a mold used for processing high-temperature materials, usually made of graphite material. Graphite has excellent high-temperature resistance and thermal conductivity, making it widely used in many industrial applications, especially in situations that require high-temperature processing and precise forming.

[0003] When the existing graphite mold is used for hot bending glass, although the graphite mold has good thermal conductivity, a large amount of heat will be generated during the hot bending process due to the high temperature. These heats accumulate inside the mold and cannot be quickly and effectively dissipated. Long-term and repeated use of the mold may increase the degree of mold wear, thereby reducing the service life of the graphite mold.

[0004] Therefore, it is necessary to design a graphite mold for hot bending glass. Summary of the Utility Model

Through the setting and use of the mold frame 6 and the cooling component 13, the mold is cooled by using the characteristics of cyclic cooling, and then by setting the cooling fan 12 and the ventilation holes, the air fluidity inside the mold is improved. The two work together to achieve fast and efficient heat dissipation, thereby reducing the loss degree of the mold and extending the service life of the mold; at the same time, the combined use of the cooling component 13, the mold frame 6, and the mold groove 7 can quickly take out the glass, reducing the cooling waiting time, and thus improving the production efficiency of the mold.

[0029] According to Figure 4 , two groups of slots 9 are opened on the upper surface of the lower mold 1, and the two groups of slots 9 are located on the front side and the back side of the lower mold 1. Two groups of inserts 10 are fixedly connected to the lower surface of the connecting plate 8, and the two groups of inserts 10 correspond to the two groups of slots 9 one by one. By setting the slots 9 and the inserts 10, the precise stability of the mold during alignment is ensured, and thus the hot-bent glass of good quality is ensured.

[0030] According to Figures 1-4 , coatings are provided on the surfaces of both the upper mold 3 and the lower mold 1. By setting the coatings, the surface performance, oxidation resistance, and hardness of the mold are improved.

[0031] According to Figure 4 , notches are opened on both sides of the mold groove 7, and handles are installed at both ends of the mold frame 6. By setting the notches and the handles, it is convenient to take out the mold frame 6, improving the practicality of the device.

[0032] According to Figures 1-3 , cooling fans 12 are installed on the inner walls of both sides of the two groups of inner cavities 11, and multiple groups of ventilation holes are opened on the outer walls of both sides of the lower mold 1. By setting the cooling fans 12 and the ventilation holes, the mold has good air fluidity inside.

Start the hydraulic cylinder 4, and the output end of the hydraulic cylinder 4 pushes the connecting plate 8 downward until the inserting block 10 is completely inserted into the inserting slot 9. At this time, the heating pressing plate 5 contacts the glass and then bends the glass thermally. After the thermal bending is completed, the two sides of the mold frame 6 are cooled by the ventilation holes on both sides. First, close the hydraulic cylinder 4, and the heating pressing plate 5 and the connecting plate 8 reset. The heat accumulates on the mold frame 6. Since the water-cooling plate 131 is in contact with the mold frame 6, the heat of the mold frame 6 is transferred to the water-cooling plate 131. Start the water pump 135 to suck the coolant out of the water tank 133. The coolant enters the suction pipe 134 along the suction pipe 134, and then flows into the water-cooling plate 131 from the water inlet pipe 136. The water-cooling plate 131 is cooled by the coolant. The coolant flows back into the water tank 133 from the water outlet pipe 132 to form a circulating cooling. Start the cooling fan 12, and the cooling fan 12 generates wind to accelerate the air circulation in the lower mold 1. After cooling for a period of time, the staff can hold the handle and lift the mold frame 6 out for subsequent demolding.
