In addition, the lower mold core is made of a material with a linear expansion coefficient smaller than that of the glass, and the upper mold core is made of a material with a linear expansion coefficient larger than that of the glass.

[0038] The bottom of the lifting plate II 53 is provided with a telescopic cylinder IV 56 around. The top of the telescopic rod of the telescopic cylinder IV 56 is provided with an anti-slip clamping seat 57. The telescopic cylinder IV 56 drives the anti-slip clamping seat 57 to approach or move away from the upper mold 58 by telescoping the telescopic rod, realizing clamping and releasing of the upper mold 58. The upper mold 58 is arranged between the anti-slip clamping seats 57. The upper mold 58 cooperates with the lower mold 8 to make the glass product forming.

[0039] A pair of circular grooves 59 are symmetrically arranged on both sides of the upper mold 58. A positioning column 510 is slidingly arranged in each of the two circular grooves 59. The lower mold 8 is provided with a positioning hole 515 corresponding to the position of the positioning column 510. The positioning column 510 of the upper mold 58 cooperates with the positioning hole 515 of the lower mold 8 to realize precise positioning of the upper mold 58 and the lower mold 8.

[0040] Two circular grooves 59 are provided with oil storage cylinders 511 for storing hydraulic oil, two positioning columns 510 are provided with piston rods 512, the piston rods 512 connect the positioning columns 510 and the pistons 513, and transmit pressure, the top of the two piston rods 512 is provided with the piston 513, the same side piston 513 is slidingly arranged in the oil storage cylinder 511, the piston 513 slides in the oil storage cylinder 511, and the space in the oil storage cylinder 511 is divided into two cavities to generate damping force, the positioning column 510 and the circular groove 59 are provided with springs 514, the springs 514 are compressed when the positioning column 510 is subjected to pressure, and the elastic potential energy is released after the external force disappears, so as to push the positioning column 510 to be clamped in the positioning hole 515.

[0041] In use, first, start the conveyor 1, stop running after conveying the lower mold 8 directly below the pretreatment assembly 4, then, the telescopic rod of the telescopic cylinder one 48 is elongated, the mounting frame one 49 is driven to descend, the cylindrical brush 412 contacts the forming cavity 91 in the lower mold 8, then, the motor two 411 drives the rotating shaft 410 to rotate, drives the cylindrical brush 412 to rotate, at the same time, the motor one 45 drives the screw rod 44 to rotate, converts the rotary motion of the screw rod 44 into the linear motion of the driving block 47, makes the driving block 47 drive the cylindrical brush 412 to move along the guide rail one 46, and the forming cavity 91 on the lower mold 8 is fully cleaned, after cleaning, the motor two 411 stops running, the telescopic rod of the telescopic cylinder one 48 is retracted, the cylindrical brush 412 is lifted, then the liquid sprayer 414 is started, the release agent storage box 415 transports the release agent to the liquid sprayer 414 through the pipeline, the liquid sprayer 414 sprays the release agent to the forming cavity 91 of the lower mold 8, at the same time, the control motor one 45 is reversed, the driving block 47 drives the liquid sprayer 414 to move along the guide rail one 46, and ensures that the release agent is uniformly sprayed in the forming cavity 91 of the lower mold 8.

[0042] After the pre-treatment is completed, the operator places the glass product substrate in the forming cavity 91 of the lower mold 8, and starts the conveyor 1 again. The lower mold 8 loaded with the glass product substrate is conveyed to be located immediately below the left-side receiving and releasing assembly 5 on the conveyor 1, and then stopped. The extension rod of the telescopic cylinder three 52 is extended, the lifting plate two 53 is driven to move downward, the guide column 54 slides in the guide sleeve 55 to ensure the stability of the downward movement of the lifting plate two 53. During the downward movement, if there is a deviation between the upper mold 58 and the lower mold 8, the positioning column 510 will be first retracted along the circular groove 59 under the pressure, the spring 514 is compressed, and at the same time, the piston rod 512 and the piston one 513 move in the oil storage cylinder 511. When the upper mold 58 and the lower mold 8 are completely aligned, the positioning column 510 is clamped into the positioning hole 515, the external force disappears, the spring 514 releases the elastic potential energy, drives the positioning column 510 to be clamped into the positioning hole 515, and at the same time drives the piston rod 512 and the piston one 513 to move in the oil storage cylinder 511. The piston one 513 divides the space in the oil storage cylinder 511 into two cavities. The hydraulic oil in the oil storage cylinder 511 will flow back and forth from one cavity to another through different small holes on the piston one 513. The friction between the hole wall and the hydraulic oil and the internal friction between the molecules of the hydraulic oil will hinder the flow of the hydraulic oil, thereby generating a damping force to ensure that the positioning column 510 is stably clamped into the positioning hole 515, and the precise positioning of the upper mold 58 and the lower mold 8 is achieved. After the molds are closed, the extension rod of the telescopic cylinder four 56 is retracted to release the upper mold 58.

[0043] The conveyor 1 is started again to convey the closed upper mold 58 and the lower mold 8 to the heating machine 6. The heating machine 6 heats and forms the substrate. After the forming is completed, the conveyor 1 continues to convey the upper mold 58 and the lower mold 8 in the closed state to the cooling machine 7. The cooling machine 7 cools the product. After the cooling is completed, the conveyor 1 stops conveying the upper mold 58 and the lower mold 8 in the closed state immediately below the right-side receiving and releasing assembly 5 on the conveyor 1. The extension rod of the telescopic cylinder three 52 is extended to lower the lifting plate two 53. Then the extension rod of the telescopic cylinder four 56 is extended to clamp the upper mold 58 from four sides. Subsequently, the extension rod of the telescopic cylinder three 52 is retracted to drive the upper mold 58 to rise and reset, thereby achieving mold opening. Finally, the extension rod of the telescopic cylinder two 93 is extended to drive the lifting plate one 94 to rise along the guide rail two 95, thereby driving the ejection pin 96 to eject the formed glass product, completing the demolding. The operator can obtain the processed glass product.
