[0026] Embodiment one, please refer to Figures 1-4 A high-precision molding device for producing special optical glass, comprising: A workbench 100, a movable rod 200 driven by a servo motor is assembled inside the workbench 100, a molding head 300 is assembled at the bottom of the movable rod 200, and a cooling liquid input pipe 600 is assembled on the side of the workbench 100; The electric rotating disc 400 is assembled in the inside of the workbench 100, the top of the electric rotating disc 400 is assembled with the mould pressing cylinder 500, the raw material is placed in the mould pressing cylinder 500, the electric rotating disc 400 is driven, the mould pressing cylinder 500 is rotated to the bottom position of the mould pressing head 300, the servo motor is driven, the moving rod 200 is driven to move downwards, the moving rod 200 drives the mould pressing head 300 assembled at the bottom of the moving rod 200 to move downwards, the mould pressing head 300 moves into the mould pressing cylinder 500, and corresponding mould pressing operation is carried out; The side surface of the moving rod 200 is fixedly connected with the bending rod 701. When the moving rod 200 drives the mould pressing head 300 to move downwards, the bending rod 701 assembled at the side surface of the moving rod 200 moves downwards at the same time.

[0027] The bottom of the workbench 100 is connected with the transmission rod 710 through the spring 709, the transmission member for transmission is assembled between the bending rod 701 and the transmission rod 710, the transmission member comprises the bending plate 702 fixed at the side surface of the bending rod 701. When the bending rod 701 moves downwards, the bending plate 702 fixedly connected with the bending rod 701 can be driven to move downwards.

[0028] The side surface of the bending plate 702 is connected with the inclined block 704 through the elastic expansion block 703, the inclined block 704 is provided with two, and the two inclined blocks 704 are symmetrically distributed about the center axis of the bending plate 702. When the bending plate 702 moves downwards, the bending plate 702 in the downward moving state is driven to move downwards through the elastic expansion block 703.

[0029] The side surface of the workbench 100 is fixedly connected with the fixed column 705, the outer side of the fixed column 705 is fixedly connected with the fixed block 706 and the fixed block 707 respectively, the outer side of the fixed column 705 is slidingly connected with the sliding block 708, the sliding block 708 is located at the side surface position of the transmission rod 710 and is in a fixed state with the transmission rod 710, the top of the transmission rod 710 is fixedly connected with the top rod 711. When the transmission rod 710 moves upwards, the top rod 711 fixedly connected with the transmission rod 710 can be driven to move upwards, the special glass after the mould pressing operation is lifted from the mould pressing cylinder 500, so that the special glass is taken out, and the whole operation process is more convenient.

[0030] In use, the raw material is placed inside the molding cylinder 500, and the electric turntable 400 is driven to rotate the molding cylinder 500 to the bottom position of the molding head 300. The servo motor is then driven to move the moving rod 200 downward, which in turn moves the molding head 300 mounted at its bottom downward. The molding head 300 moves into the molding cylinder 500 to perform the corresponding molding operation. During the downward movement of the molding head 300 by the moving rod 200, the bending rod 701 mounted on the side of the moving rod 200 moves downward along with it, causing the bending rod 701 to drive the bending plate 702 fixedly connected to it to move downward. The bending plate 702, which is in a downward moving state, then drives the inclined block 704 downward through the elastic telescopic block 703. When the inclined blocks 704 on both sides move to the fixed block 706, the inclined block 704 is squeezed by the fixed block 706, causing the inclined block 704 to compress the elastic telescopic block 703 and move closer to the bending plate 702, so that the inclined block 704 can pass over the fixed block 706. When the inclined block 704 moves to the sliding block 708, it moves downward from the top of the sliding block 708. At this time, the sliding block 708 is restricted by the fixed block 707 and cannot move. Similarly, the inclined block 704 can move downward. When the slider 708 moves to the side position of the fixed block 707 and the molding operation is performed, the inclined blocks 704 remain on both sides of the fixed block 707. After the molding operation is completed, the moving rod 200 drives the molding head 300 to reset, and the inclined blocks 704 move upward to reset. At this time, the inclined blocks 704 on both sides move upward from the bottom of the slider 708, thereby squeezing the slider 708 and driving it to move upward together. The slider 708 then drives the transmission rod 710 fixedly connected to it to move upward, so that the transmission rod 710 drives the top rod 711 fixedly connected to it to move upward. The special glass, after molding, is lifted from the molding cylinder 500, and can then be removed. The moving rod 200 drives the molding head 300 to continue moving upward to reset. When the sliding block 708 moves to the bottom of the fixed block 706, the sliding block 708 is restricted by the fixed block 706 and cannot move further. Similarly, the inclined block 704 compresses the elastic telescopic block 703 and moves, allowing the inclined block 704 to pass over both the sliding block 708 and the fixed block 706 simultaneously. At this point, the sliding block 708 and the transmission rod 710 are no longer restricted and can be reset under the action of the spring 709.

When the rotating rod two 809 reciprocating rotates, the flow guide plate 811 can be driven to reciprocating rotate, and the cooling liquid input through the cooling liquid input pipeline 600 can be guided to each position of the special glass just lifted, which improves the cooling efficiency of the device for the special glass and makes it more convenient to be taken out.

[0034] When in use, on the basis of the embodiment one, after the mould pressing operation is completed, the liquid pump is started to input the cooling liquid into the cooling liquid input pipe 600, the bending plate 702 in the upward moving state can drive the gear rod 801 fixedly connected therewith to move upward, so that the gear rod 801 drives the gear 803 engaged therewith to rotate, the gear 803 in the rotating state can drive the rotating rod one 802 fixedly connected therewith to rotate, so that the rotating rod one 802 drives the cam 804 fixedly connected therewith to rotate, when the protruding part of the cam 804 rotates to the top position of the stress rod 806, the stress rod 806 can be extruded and moved downward, cooperating with the hydraulic chamber one 805 slidably connected with the stress rod 806 through the piston, so that the stress rod 806 extrudes the oil originally stored in the hydraulic chamber one 805 during the downward movement, the oil is extruded and flows to the side close to the arc-shaped rod one 807, driving the arc-shaped rod one 807 slidably connected with the hydraulic chamber one 805 through the piston to extend out of the hydraulic chamber one 805, the arc-shaped rod one 807 in the moving state can drive the stress plate 810 fixedly connected therewith to move, so that the stress plate 810 drives the rotating rod two 809 fixedly connected therewith to rotate by a certain angle, and the rotating rod two 809 drives the guide plate 811 fixedly connected therewith to rotate by a certain angle; when the protruding part of the cam 804 is away from the stress rod 806, the stress rod 806 can be reset under the action of the spring two 808, and the guide plate 811 is reset in the same way, so that the guide plate 811 is in the reciprocating rotating state, and the cooling liquid input through the cooling liquid input pipe 600 is guided to each position of the special glass just lifted up.

The transmission plate 908 is located at the bottom of the downward rod 906 and is in contact with the downward rod 906. When the downward rod 906 extends from the hydraulic chamber three 905, the downward rod 906 immediately extrudes the transmission plate 908 downward, and applies additional force to the cleaning brush 904 through the transmission plate 908 and the elastic expansion block two 907, thereby improving the friction between the cleaning brush 904 and the workbench 100, and improving the cleaning effect of the cleaning brush 904.
