[0023] 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.

[0024] Please see Figure 1-6 The present invention provides a technical solution: including a lower mold 1 and an upper mold 2, a mold 3 is connected to the top of the lower mold 1, and multiple sets of guide blocks 4 are provided at the top of the lower mold 1. The guide blocks 4 are located on the outer ring of the mold 3. A groove 5 is opened on one side of the upper mold 2 corresponding to the mold 3, and an fitting groove 6 is opened on one side of the upper mold 2 corresponding to the guide block 4. Multiple air passages 7 and air pipes 8 are opened inside the lower mold 1, and an air extraction mechanism 9 is slidably arranged inside the air pipes 8.

[0025] Reference Figure 5 As shown, the air extraction mechanism 9 includes a connecting rod 91. One end of the connecting rod 91 is connected to an air extraction piston 92 corresponding to the air pipe 8. The air extraction piston 92 is slidably connected to the air pipe 8. The other end of the connecting rod 91 is U-shaped and has a rotating ring 93. The rotating ring 93 pulls the connecting rod 91, which in turn drives each air extraction piston 92, thereby extracting air from the air pipe 8 and the air passage 7. A bracket 94 is connected to one side of the rotating ring 93. After the connecting rod 91 is pulled to a suitable position, the rotating ring 93 is rotated to lock the bracket 94 into the limiting groove 10, thereby limiting the connecting rod 91.

[0026] Reference Figure 2As shown, the upper mold 2 is provided with two sets of water storage tanks 13. A connecting water channel 14 is provided on the side of the water storage tanks 13 that are close to each other. Water pipe connectors 15 are provided on both sides of the upper mold 2 corresponding to the water storage tanks 13. Water is injected into the water storage tank 13 by connecting an external water pipe to one end of the water pipe connector 15. The water flows to the other water storage tank 13 through the connecting water channel 14 and is discharged through the water pipe connector 15 on the other side, thereby removing the heat of the upper mold 2 and accelerating the cooling speed of the lower mold 1 and the upper mold 2. Mounting holes 16 are provided on one side of both the lower mold 1 and the upper mold 2. The lower mold 1 and the upper mold 2 can be connected and installed on a suitable device through the mounting holes 16.

[0027] Reference Figure 1 As shown, a movable groove 911 is provided on one side of the lower mold 1 corresponding to the connecting rod 91, and a limit groove 10 is provided on one side of the movable groove 911 corresponding to the bracket 94. The connecting rod 91 can be pulled through the movable groove 911.

[0028] Reference Figure 2 As shown, the connecting rod 91 passes through each air pipe 8, and the suction piston 92 is slidably connected to the air pipe 8. When the connecting rod 91 is pulled, each suction piston 92 can be pulled to slide inside the air pipe 8 at the same time, thereby performing suction.

[0029] Reference Figure 3 and Figure 4 As shown, the air passage 7 includes an air extraction passage 71 opened in the lower mold 1. A compression passage 72 is provided on one side of the air extraction passage 71, and an installation passage 73 is connected to the other end of the compression passage 72. The installation passage 73 is located inside the mold 3. When the air extraction mechanism 9 is pulled, the sliding of the air extraction piston 92 will draw air from the air pipe 8, thereby drawing air from the air extraction passage 71. The compression passage 72 compresses the air, increases the air pressure, and thus accelerates the drawing of air from the installation passage 73.

[0030] Reference Figure 4 As shown, a return spring 11 is connected to one side of the inner wall of the mounting channel 73, and an airtight frame 12 is connected to the top of the return spring 11. When the air in the mounting channel 73 is extracted, the negative pressure will pull the airtight frame 12 downward, thereby adsorbing the glass onto the top of the mold 3. When the glass sheet is fixed and heated, the air expands during the heating operation, and the mounting channel 73 returns to its original position against the airtight frame 12, ensuring the flatness of the surface of the mold 3.

[0031] Reference Figure 6 As shown, the airtight frame 12 includes a breathable panel frame 121, which is connected by an attached... Figure 6 It can be seen that the ventilated plate frame 121 has multiple vent holes. When the airtight frame 12 is subjected to air pressure drop, it can better drive the sealing plug 123 to drop. The top of the ventilated plate frame 121 is connected to a support rod 122, and the top of the support rod 122 is connected to a sealing plug 123.

[0032] The implementation principle of this application is as follows: A glass sheet is placed on top of the mold 3. At the same time, the guide blocks 4 around the mold 3 play a good guiding and limiting role, which can guide and position the glass sheet immediately. When the glass sheet is placed on the mold 3, the suction mechanism 9 is pulled to extract the air in the air passage 7 through the air pipe 8, thereby driving the airtight frame 12 to descend and thus adsorb the glass sheet. The suction mechanism 9 is positioned by the limiting groove 10 to ensure a stable effect, thereby heating the lower mold 1 with the glass sheet. After heating to a suitable temperature, the upper mold 2 is pressed down above the lower mold 1, thereby forming the heated glass sheet through the cooperation between the groove 5 and the mold 3. Water is injected into the water storage tank 13 in the upper mold 2 through the external water pipe connected to the water pipe connector 15. The water is connected through the water channel 14, and the water carries away the heat and is discharged through another set of water pipe connectors 15 for rapid cooling.
