[0019] The die conveying mechanism VII places the die, and the die casting mechanism IV casts the die. The die frame conveyor belt 1 is located behind the die frame lifting mechanism I, and the die frame pick-up and placement mechanism II is located above the die frame lifting mechanism I. The die grabbing mechanism III is located above the die frame conveyor belt 1, and the die casting mechanism IV is located on one side of the die frame conveyor belt 1. The die frame limiting mechanism V is located in front of the die frame lifting mechanism I, and the die frame clamping mechanism VI is located on the die frame conveyor belt 1.

[0020] The die frame lifting mechanism 1 includes a lifting transmission mechanism, a lifting motor 2, and a die frame placement plate 3. The lifting transmission mechanism is provided in two groups, each group including a placement plate guide rod 4, a guide seat 5, a lifting chain 6, an upper sprocket 7, and a lower sprocket 8. The guide seat 5 is slidably connected to the placement plate guide rod 4 in the vertical direction. The guide seat 5 is fixedly connected to the lifting chain 6, and the upper and lower ends of the lifting chain 6 are respectively connected to the upper sprocket 7 and the lower sprocket 8 by chain transmission. The lifting motor 2 is connected to the upper sprocket 7 to drive the upper sprocket 7 to rotate. The ends of the die frame placement plate 3 are fixedly connected to the two guide seats 5.

[0021] It should be understood that the mold frame lifting mechanism I is not limited to the above-mentioned form of lifting the mold frame by the lifting motor 2. In other embodiments, the lifting method of the mold frame lifting mechanism I can also be: lifting the mold frame by a hydraulic lifting platform, lifting the mold frame by an AGV trolley, etc.

[0022] The mold frame limiting mechanism V includes two groups of limiting frames 15 and an opening and closing cylinder 16. The limiting frame 15 includes a limiting frame rotating shaft 151. The two ends of the opening and closing cylinder 16 are respectively connected to the limiting frame rotating shafts 151 of the two groups of limiting frames 15 to drive the limiting frame rotating shafts 151 to rotate. The opening and closing cylinder 16 drives the limiting frame rotating shafts 151 to rotate, so that the two groups of limiting frames 15 rotate to both sides, the limiting frames 15 open, and the mold frame can be placed on the mold frame placement plate 3; the opening and closing cylinder 16 drives the limiting frame rotating shafts 151 to rotate, so that the two groups of limiting frames 15 rotate inward, the limiting frames 15 close, and the mold frame on the mold frame placement plate 3 is limited by the two groups of limiting frames 15, so that the mold frame can only move up and down with the mold frame placement plate 3.

[0023] The die frame pick-and-place mechanism II includes two die frame clamping arms 9, a clamping cylinder 10, a lifting cylinder 11, and a linear module 12. The two ends of the clamping cylinder 10 are connected to the two die frame clamping arms 9, respectively. The lower end of the lifting cylinder 11 is connected to the clamping cylinder 10 to drive the clamping cylinder 10 to rise and fall. The linear module 12 is connected to the lifting cylinder 11 to drive the lifting cylinder 11 to translate back and forth along the conveying direction of the die frame conveyor belt 1.

[0024] The mold frame clamping mechanism VI includes two rotary clamping cylinders 17. The two rotary clamping cylinders 17 are mounted on the frame of the mold frame conveyor belt 1, and the two rotary clamping cylinders 17 are arranged relative to each other in the front and rear directions. The rotary arm 171 of the front rotary clamping cylinder 17 is first in a downward rotation state, and the rotary arm 171 of the rear rotary clamping cylinder 17 is first in an upright state. When the mold frame on the mold frame conveyor belt 1 moves to abut the rotary arm of the rear rotary clamping cylinder 17, the rotary arm 171 of the front rotary clamping cylinder 17 rotates upward, and the two rotary clamping cylinders 17 drive the rotary arms 171 to clamp the mold frame, so that the mold frame is fixed between the two rotary arms 171. After the mold frame is filled with cast molds, the rotary arm 171 of the rotary clamping cylinder 17 rotates downward, allowing the mold frame to continue to move backward along with the mold frame conveyor belt 1.

[0025] The rear end of the mold frame conveyor belt 1 is provided with a mold frame baffle 13. When the mold frame is conveyed to the rear end of the mold frame conveyor belt 1, the mold frame is blocked by the mold frame baffle 13 and cannot move. The mold frame conveyor belt 1 is provided with mold frame stop bars 14 on the left and right sides. The mold frame stop bars 14 are used to limit the mold frame on the left and right sides during conveyance, preventing the mold frame from shifting left and right during conveyance, and also serve as a guide for the mold frame during conveyance. The fully automatic lens casting machine works as follows:

[0026] 1. The opening and closing cylinder 16 drives the two sets of limit frames 15 to open, stacking the die frame on the die frame placement plate 3. Then the opening and closing cylinder 16 drives the two sets of limit frames 15 to close, lifting the die frame placement plate 3 so that the die frame on the die frame placement plate 3 moves upward;

[0027] 2. The die frame pick-up and placement mechanism II grabs the uppermost die frame on the die frame placement plate 3 and places it on the die frame conveyor belt 1;

[0028] 3. When the die frame on the die frame conveyor belt 1 moves to the die frame clamping mechanism VI, the die frame is fixed and limited between the two rotating arms 171;

[0029] 4. The die is placed on the die conveying mechanism VII, the die casting mechanism IV casts the die, the die grabbing mechanism III grabs the die cast by the die casting mechanism IV, and places it in the die frame on the die frame conveyor belt 1;

[0030] 5. After the die frame is filled with cast dies, the rotary arm of the rotary clamping cylinder rotates downward, allowing the die frame to continue to move backward along with the die frame conveyor belt 1;

[0031] 6. The die frame is conveyed to the rear end of the die frame conveyor belt 1 along with the die frame conveyor belt 1, and is stopped by the die frame baffle 13 and no longer moves, and the die frame is collected.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
