[0029] like Figure 1 and Figure 2 As shown, the present application discloses a glass hot pressing mold, including a first mold 1 and a second mold 2 adapted to the first mold 1, the first mold 1 is provided with a first mold forming groove 101, the second mold 2 is provided with a second mold forming groove 201, the first mold forming groove 101 is provided with a plurality of grooves 102, each of the grooves 102 is provided with a plurality of secondary air channels 103 connected to the main air channel, after the first mold 1 and the second mold 2 are closed, the first mold forming groove 101 and the second mold forming groove 201 can enclose a mold cavity, and each of the secondary air channels 103 can discharge the gas in the mold cavity.

[0030] In the present application, a first mold forming groove 101 is provided on the first mold 1, and a second mold forming groove 201 is provided on the second mold 2. When the first mold 1 and the second mold 2 are pressed together, the first mold forming groove 101 and the second mold forming groove 201 enclose a mold cavity, and the structure is simple. It can be seen from this that when the first mold forming groove 101 and the second mold forming groove 201 enclose the mold cavity, the excess gas in the mold cavity tends to gather in the mold cavity. Moreover, since there is also a glass body in the mold cavity, the excess gas will gather anywhere between the glass body and the inner side walls of the first mold forming groove 101 and the second mold forming groove 201, especially at the ribs of the glass body. Therefore, the present application provides a plurality of secondary air channels 103 on the bottom surface of the plurality of grooves 102 that form the ribs, for discharging excess gas.

[0031] Specifically, the diameter of the secondary air channel 103 is small to prevent a small amount of glass blank from entering the secondary air channel 103 due to pressure during the pressing process, which would not only affect the surface roughness of the glass blank but also increase the difficulty of demolding. Therefore, the diameter of the secondary air channel 103 is less than 0.1 mm.

[0032] It is conceivable that the secondary air channel 103 can be configured as a micro-pore structure, which can also discharge excess gas.

[0033] The secondary air channel 103 is connected to the main air channel (not shown) for exhausting excess gas. The secondary air channel 103 can also be directly connected to the outer peripheral surface of the first mold 1 to communicate with the outside world and also exhaust gas.

[0038] In some possible implementations, the first mounting hole 105 and the second mounting hole 203 are both formed as countersunk holes.

[0039] In some possible implementations, the guide post 106 is disposed between two of the first mounting holes 105 , and the guide post groove 204 is disposed between two of the second mounting holes 203 .

[0040] In some possible implementations, the guide post 106 is a rectangular parallelepiped structure, and R-arc corners are formed on its four edges.

[0041] In some embodiments, the edge of the guide post 106 may also be formed as a chamfered structure.

[0042] In some embodiments, the guide post 106 is a rectangular parallelepiped structure, and the guide post groove 204 forms a corresponding rectangular parallelepiped groove structure. The guide post 106 can be inserted into the guide post groove 204 to position and limit the first mold 1 and the second mold 2.

[0043] In some embodiments, the guide post 106 is a cylindrical structure, and the guide post groove 204 forms a corresponding cylindrical groove structure. The guide post 106 can be inserted into the guide post groove 204 to position and limit the first mold 1 and the second mold 2.

[0044] In some embodiments, the guide post 106 and the guide post slot 204 may be replaced by other structures as long as they satisfy the positioning and limiting functions.

[0045] 101 is arranged along the width direction of the first mold 1, and each of the grooves 102 is arranged in the central area of the first mold forming groove 101.

[0046] In some possible implementations, the grooves 102 are arranged in parallel.

[0047] In some possible implementations, the air inlets of the secondary air channels 103 are located in the central area of the grooves 102 and are arranged at equal intervals.
