[0023] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0024] This application discloses a lens mold clamping device, such as Figure 1 and Figure 2 As shown, the device includes a base 1, a clamping mechanism 3 mounted on the base 1 for clamping the lower mold base 11, and an electric push rod 13 mounted on the top of the base 1 for driving the upper mold base 12 to move vertically. An exhaust gas treatment mechanism 2 is mounted on the base 1. The exhaust gas treatment mechanism 2 includes a UV photolysis unit 21 mounted on the top of the base 1, an air suction hood 22 mounted on the top of the base 1, and a negative pressure assembly mounted on the top of the base 1. The air inlet pipe of the UV photolysis unit 21 is connected to the air suction hood 22 through the negative pressure assembly. First, the negative pressure assembly generates suction in the air suction hood 22. Then, the harmful gases pass sequentially through the air suction hood 22 and the negative pressure assembly before entering the UV photolysis unit 21. The UV photolysis unit 21 then treats the harmful gases, thereby reducing the amount of harmful gases in the workshop and thus reducing the inhalation of harmful gases by workers. In summary, this application can reduce the inhalation of harmful gases by workers.

[0025] like Figure 1 As shown, the clamping mechanism 3 includes a mounting groove 31 formed in the base 1, a double-threaded screw 32 horizontally rotatably connected to the inner wall of the mounting groove 31 via bearings, a handwheel 33 fixed to one end of the double-threaded screw 32, and a first guide rod 34 horizontally fixed to the inner wall of the mounting groove 31. Clamping plates 35 are threaded to both ends of the double-threaded screw 32, and both clamping plates 35 slide along the length of the base 1 and are connected to the first guide rod 34. Two slotted holes 311 are formed in the top wall of the mounting groove 31, and the two clamping plates 35 slide along the length of the base 1 and are connected to the two slotted holes 311. When it is necessary to clamp and fix the lower mold base 11, the double-threaded screw 32 is first driven to rotate by the handwheel 33. The rotation of the double-threaded screw 32 drives the two clamping plates 35 to move towards each other, thus clamping and fixing the lower mold base 11. In summary, the clamping mechanism 3 facilitates the clamping and fixing of the lower mold base 11.

[0026] like Figure 1 and Figure 2As shown, the negative pressure assembly includes a negative pressure pump 23 connected to the air inlet pipe of the UV photolysis unit 21, a dust filter box 24 connected to the air inlet of the negative pressure pump 23, and a first negative pressure pipe 25 connected to the side of the dust filter box 24 away from the negative pressure pump 23; a first electric valve is installed on the first negative pressure pipe 25, and the end of the first negative pressure pipe 25 away from the dust filter box 24 is connected to the suction hood 22; a first through hole 241 is opened on the top of the dust filter box 24, a filter plate 26 is vertically slidably arranged in the first through hole 241, a pressure plate 27 is fixedly connected to the top of the filter plate 26, a sealing ring 28 is provided between the pressure plate 27 and the dust filter box 24, and a driving component for driving the pressure plate 27 to move vertically is installed on the top of the dust filter box 24. The negative pressure pump 23 and the first negative pressure pipe 25 enable the suction hood 22 to generate suction; the pressure plate 27 and the sealing ring 28 can seal the first through hole 241; the driving component facilitates the removal of the filter plate 26 for cleaning.

[0027] like Figure 2 and Figure 3 As shown, the driving component includes a vertical plate 29 fixedly to the top of the dust filter box 24, a horizontal plate 291 fixedly to one side of the top of the vertical plate 29, and a cylinder 292 fixedly to the top of the horizontal plate 291; the piston rod of the cylinder 292 is fixedly to the top of the pressure plate 27. When it is necessary to drive the pressure plate 27 to move, the cylinder 292 can be activated; in summary, the driving component is designed to facilitate the movement of the pressure plate 27.

[0028] like Figures 2-4As shown, a vibration mechanism 4 for vibrating the filter plate 26 is installed on the side wall of the vertical plate 29. The filter plate 26 is a metal plate. The vibration mechanism 4 includes a fixed frame 41 fixed to the side of the vertical plate 29 away from the filter plate 26, a second guide rod 42 horizontally fixed to the fixed frame 41, a first sliding sleeve 43 slidably connected to the second guide rod 42 in the horizontal direction, a vibration spring 44 horizontally fixed between the first sliding sleeve 43 and the fixed frame 41, and a vibration plate 45 fixed to the top of the first sliding sleeve 43. The end of the vibration plate 45 away from the first sliding sleeve 43 passes through the vertical plate 29 and can abut against the filter plate 26. The filter plate 26 is provided with a strike plate 261, which is located on the filter plate 26 and is struck by the vibration plate 45. The end of the vibration plate 45 near the pressure plate 27 is provided with inclined surfaces 451 at its bottom and top, and both inclined surfaces 451 are matched with the pressure plate 27. The piston rod of cylinder 292 drives the pressure plate 27 to move upward. Then, under the action of inclined plane 451, the pressure plate 27 drives the vibrating plate 45 to move away from the filter plate 26. The movement of the vibrating plate 45 away from the filter plate 26 drives the first sliding sleeve 43 to move away from the filter plate 26. At this time, the first sliding sleeve 43 presses against the vibration spring 44. When the pressure plate 27 separates from the vibrating plate 45, the first sliding sleeve 43 hits the impacted plate 261 under the action of the vibration spring 44. This makes the filter plate 26 vibrate, which facilitates the cleaning of the filter plate 26. In summary, the vibration mechanism 4 facilitates the cleaning of the filter plate 26.

[0029] like Figures 2-3 As shown, the clamping device also includes a receiving mechanism 5 for blocking the first through hole 241 and for collecting the dust vibrating down from the filter plate 26. The receiving mechanism 5 includes a dovetail groove 51 opened on the top of the dust filter box 24, a dovetail plate 52 slidably connected to the dovetail groove 51 in the horizontal direction, a return spring 53 horizontally fixed to one side of the dovetail plate 52, and a dust receiving frame 54 fixed to the top of the dovetail plate 52. The end of the return spring 53 away from the dovetail plate 52 is fixed to the inner wall of one end of the dovetail groove 51. A drawer 55 is installed on the dust receiving frame 54. The receiving mechanism 5 also includes a transmission component 56 for driving the dust receiving frame 54 to move. When the pressure plate 27 moves the filter plate 26 upward to a certain position, the transmission component 56 drives the dust collection frame 54 to move closer to the first through hole 241. This can block the first through hole 241 and collect the dust that vibrates down from the filter plate 26. In summary, the collection mechanism 5 is designed to block the first through hole 241 and collect the dust that vibrates down from the filter plate 26.

[0030] like Figures 2-3As shown, the transmission assembly 56 includes a support plate 561 horizontally fixed to the side wall of the vertical plate 29, a third guide rod 562 vertically fixed to the top of the support plate 561, and a second sliding sleeve 563 vertically slidably connected to the third guide rod 562; a pull rope 564 is provided between the second sliding sleeve 563 and the ash receiving frame 54; a connecting plate 565 is horizontally bolted to one side of the pressure plate 27; a connecting rod 566 is vertically threaded to the end of the connecting plate 565 away from the pressure plate 27; a push plate 567 is fixed to the top of the connecting rod 566; the push plate 567 can push the second sliding sleeve 563 to move upward; the connecting plate 565, the connecting rod 566, the second sliding sleeve 563 and the push plate 567 are all staggered with the vibrating plate 45. When the pressure plate 27 drives the push plate 567 to a certain position, the push plate 567 drives the second sliding sleeve 563 to move upward. Then, under the action of the pull rope 564, the second sliding sleeve 563 drives the dust receiving frame 54 to move towards the first through hole 241, thereby blocking the first through hole 241 and reducing the amount of dust entering the first through hole 241. In summary, the transmission component 56 is designed to facilitate the movement of the dust receiving frame 54.

[0031] like Figures 2-3 As shown, the bottom of the dovetail groove 51 is vertically and sealed to multiple branch pipes 57. The bottom of the multiple branch pipes 57 is horizontally connected to a second negative pressure pipe 58. A second electric valve is installed on the second negative pressure pipe 58, and one end of the second negative pressure pipe 58 is sealed through the side wall of the dust filter box 24 and connected to the first negative pressure pipe 25. The second negative pressure pipe 58 and the branch pipes 57 facilitate the cleaning of the dovetail groove 51.

[0032] like Figure 2 and Figure 5 As shown, the dust filter box 24 has a dust discharge hole 242 at its bottom, and a third through hole 14 is provided on the base 1, corresponding to the dust discharge hole 242. The bottom of the dust discharge hole 242 has multiple slots 243, each slot 243 containing a locking block 61. A collection box 6 is fixedly connected to the bottom of each locking block 61, and a sealing gasket 62 is provided between the collection box 6 and the dust filter box 24. A pull rod 63 is fixedly connected to the bottom of the collection box 6. The collection box 6 facilitates the handling of dust within the dust filter box 24.

[0033] like Figure 2 , Figure 5 and Figure 6As shown, a limiting mechanism 7 for limiting the bottom of the collection box 6 is installed in the third through hole 14. The limiting mechanism 7 includes a receiving groove 71 opened on one side of the third through hole 14, a vertical tube 72 vertically rotatably connected to the inner wall of the receiving groove 71 via a bearing, a vertical rod 73 vertically arranged in the vertical tube 72, a gear 74 sleeved and fixed to the outer wall of the vertical tube 72, and a rack 75 meshing with the gear 74; a connecting lug 76 for the rack 75 to slide horizontally is fixed to the top wall of the receiving groove 71, and one end of the rack 75 abuts against the bottom of the collection box 6; a settling groove 244 is opened at the bottom of the dust filter box 244, and the inner edge of the settling groove 244 is... A buffer plate 77 is vertically slidably connected, and multiple buffer springs 78 are vertically fixed to the bottom of the buffer plate 77. The end of each buffer spring 78 away from the buffer plate 77 is fixed to the bottom of the settling trough 244. The end of the vertical rod 73 away from the vertical tube 72 passes through the base 1 and the dust collection box in sequence and is fixed to the bottom of the buffer plate 77. A sealing plate 262 is fixed to the bottom of the filter plate 26. The filter plate 26 can drive the buffer plate 77 to move into the settling trough 244. Multiple spiral blocks 731 are fixed to the side wall of the vertical rod 73. Multiple spiral grooves 721 are opened on the inner wall of the vertical tube 72. The spiral blocks 731 and the spiral grooves 721 are matched one by one. When the filter plate 26 moves to a certain position in the dust filter box 24 under the action of the cylinder 292, the filter plate 26 drives the buffer plate 77 to move downward. The downward movement of the buffer plate 77 drives the vertical rod 73 to move downward. At this time, the vertical rod 73 drives the vertical tube 72 to rotate under the action of the rotating block 731 and the rotating groove 721. The rotation of the vertical tube 72 drives the gear 74 to rotate. The rotation of the gear 74 drives the rack 75 to move towards the bottom of the collection box 6. This allows the top of the rack 75 to abut against the bottom of the collection box 6, thereby limiting the collection box 6. In summary, the limiting mechanism 7 is provided to facilitate the limiting of the collection box 6.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
