Description

Technical Field

[0001] The utility model relates to the technical field of glass production, in particular to a device for cooling and forming curved glass. Background Art

[0002] The existing molded glass on the market has a wide range of applications and is a commonly used method for producing curved glass. After the glass is heated and formed, it enters the cooling and fixing stage. Water cooling is used to lower the mold temperature and the glass temperature so that the glass is fixed in shape.

[0003] However, after the existing curved glass is heated and formed, it directly enters the cooling and shaping process. The sudden and large temperature difference causes the glass to have defects or be scrapped, as well as glass rebound and the curvature of the curved glass to be unqualified. Therefore, we have proposed a device for cooling and shaping curved glass to solve the above problems. Utility Model Content

[0015] 3.Beneficial effects:

[0016] The technical solution provided by the present invention is compared with the prior art. The present invention is used for a device for cooling and forming curved glass. The specific contents are as follows:

[0017] (1) After the mold is heated and molded, the door is opened and the mold is pushed into the cooling chamber for cooling. The mold is then pushed to the top of the heating plate and fixed by the molding assembly. While the mold is cooling, the heating wire is kept at the pre-adjusted temperature. The heat of the heating wire acts on the mold through the heating plate, slowly lowering the mold temperature and adding a speed bump between high and low temperatures. This reduces or eliminates the internal stress of the glass after molding, solves or reduces the rebound of the glass, and ensures that the temperature difference is gradually and orderly reduced in steps to avoid sudden changes in process temperature, which may cause cracks, pitting and other surface problems in the glass.

[0018] (2) When the heating wire needs to be replaced, push the baffles on the upper and lower sides of the cover at the same time to separate the baffles from the cover, and then pull out the heating wire. Then take out the heating wire to be installed, insert the heating wire into the heating wire slot after passing through the slot, and make the heating wire pass through the baffle and press against the outer wall of the cooling chamber. Then make the cover drive the positioning rod to insert into the positioning slot. When the cover presses against the curved surface of the baffle, the baffle overcomes the spring force and moves away from the cover. The cover is put on the outside of the heating wire through the through hole. When the inner side of the cover presses against the baffle, the cover and the baffle are misaligned. The baffle is reset by the spring and presses against the outside of the cover, thereby fixing the cover and the heating wire. Through this quick disassembly and assembly mechanism, the heating wire can be easily replaced by quickly disassembling the cover. BRIEF DESCRIPTION OF THE DRAWINGS

While the mold 6 is cooling, the heating wire 5 is maintained at the pre-adjusted temperature. The heat of the heating wire 5 acts on the mold 6 through the heating plate 3, slowly lowering the temperature of the mold 6, so that the mold 6 adds a speed bump between high temperature and low temperature, reducing or eliminating the internal stress of the glass after molding, solving or reducing the rebound of the glass, and ensuring that the temperature difference is gradually and orderly reduced in steps to avoid sudden changes in process temperature, which may cause cracks, pitting and other surface problems in the glass.
