Description

Technical Field

[0001] This utility model relates to the field of glass hot bending forming mold technology, specifically an improved structure of glass hot bending forming mold. Background Technology

[0002] Glass hot bending is a process in which glass is placed in the forming groove of the lower mold, and then the upper mold is moved into the lower mold to press the glass, thus achieving the hot bending of the glass.

[0003] In the glass hot bending forming mold application document with application number 202322405983.4, a feeding platform is formed on one side of the forming groove of the lower mold, and the feeding platform is set inclined downward from the side of the forming groove toward the center of the forming groove. This allows the feeding platform to support the glass to be formed. At the same time, when the glass to be formed is heated and softened, the inclined setting of the feeding platform makes it easy for the glass to be formed to slide into the forming groove. This avoids the edge of the glass to be formed from being stuck to the mold due to excessive thermal expansion during the heating process and not being able to slide completely into the forming groove. This also prevents defects such as steps and extrusion marks from appearing in the glass to be formed when the mold is closed, thereby improving the yield of glass hot bending forming.

[0004] Although the above-mentioned applications meet the user's needs to a certain extent, there are still some defects in the use process. The specific problems are as follows: when glass is hot-pressed, the glass is squeezed and formed, resulting in the glass only being subjected to extrusion force during the forming process. This makes the glass prone to breakage when squeezed, and the glass is not easily evenly distributed during extrusion, resulting in poor glass hot bending forming effect. Based on this, this utility model designs an improved structure for glass hot bending forming mold to solve the above problems. Utility Model Content

[0005] This invention provides an improved structure for a glass hot bending forming mold, which can effectively solve the problems mentioned in the background art.

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] Example: Figure 1-3 As shown, this utility model provides a technical solution: an improved structure for a glass hot bending forming mold, including a support column 1, a lower mold 2 disposed on the top of the support column 1, and an upper mold 3 disposed on the top of the lower mold 2. A slider 5 is mounted on the top of the support column 1 by screws. A spring damper 4 is mounted on both ends of the slider 5 by screws. Both ends of the spring damper 4 are fixedly installed inside the lower mold 2. An electric push rod 6 is mounted between the two support columns 1 by screws. A drive motor 7 is mounted on one end of the electric push rod 6 by screws. A cam 8 is fixedly connected to the output shaft of the drive motor 7. Fixing blocks 9 are fixedly installed on both ends of the bottom of the lower mold 2. A mounting box 10 is set at one end of the bottom of the lower mold 2. A return spring 11 is welded to the top of the mounting box 10. A push column 12 is fixedly installed on the top of the return spring 11. A push plate 13 is mounted on the bottom of the push column 12 by screws. An air outlet pipe 14 is fixedly connected through one end of the mounting box 10. A cooling tank 15 is set inside the lower mold 2. One end of the air outlet pipe 14 is connected to the cooling tank 15 by threads.

[0020] The longitudinal section of slider 5 is T-shaped. Sliding slider 5 is slidably connected to the inside of lower mold 2 to ensure the stability of the movement of lower mold 2 and enable lower mold 2 to better buffer.

[0021] The cam 8 is located between two fixed blocks 9. The ends of the fixed blocks 9 are provided with rounded corners to facilitate the movement of the fixed blocks 9, thereby achieving the shaking treatment of the lower mold 2 and avoiding the problem of jamming between the lower mold 2 and the cam 8.

[0022] The push plate 13 is slidably connected to the inside of the mounting box 10. The inner wall of the mounting box 10 is in contact with the outer side of the push plate 13, which facilitates pushing the gas inside the push plate 13 into the gas outlet pipe 14.

[0023] One-way valves are fixedly connected to both ends of the bottom of the mounting box 10. The two one-way valves are in opposite directions. One of the one-way valves is fixedly connected to the vent pipe 14 to prevent the gas inside the vent pipe 14 from flowing back into the mounting box 10 and affecting the heat dissipation of the lower mold 2.

[0024] After the glass is placed into the lower mold 2, the upper mold 3 is closed. The lower mold 2 is then heated to melt the glass into a specific shape. During the glass forming process, the drive motor 7 is activated, causing the cam 8 to rotate. The cam 8 continuously contacts the fixed block 9, pushing it to move. At this time, the use of the spring damper 4 allows the lower mold 2 and upper mold 3 to reciprocate, resulting in more even distribution of the glass between them and a better forming effect. After the glass is formed, the electric push rod 6 is activated, driving the drive motor... The motor 7 and cam 8 move, moving cam 8 to the top of push plate 13. As cam 8 rotates, it continuously drives push plate 13 to move, causing push plate 13 to move inside mounting box 10. This allows the gas inside mounting box 10 to enter cooling tank 15 through exhaust pipe 14, cooling the glass inside lower mold 2. This enables the glass to be formed quickly, improving the efficiency of glass forming. Furthermore, the use of spring damper 4 and slider 5 connects support column 1 and lower mold 2, which can buffer the lower mold 2 when it is impacted, reducing damage to the lower mold 2 and increasing its service life.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
