[0048] The working principle or structural principle of the precision casting circular ring recycling production line of this structure: Please refer to Figures 1 to 6 :

[0049] First, the casting film shell mounting robot 102 clamps the uncast wax mold film shell and places it at the solution outlet of the wax mold film shell casting device 101. At this time, the wax mold film shell casting device 101 casts the wax mold film shell.

[0050] Then, the film shell mounting robot 102 clamps the cast wax mold film shell and places it in the casting film shell placement groove 212. At this time, the drive motor 104 does not work, that is, the drive motor 104 does not drive the driven gear 105 to drive the driven tooth 209 to drive the driving hollow rotating part 208, the vertical connecting plate 210, the driven hollow rotating part 207, the casting film shell bearing plate 211, and the casting film shell placement groove 212 to rotate.

[0051] Finally, after the cast wax mold shell is placed in the casting mold shell placement groove 212, the driving motor 104 operates at this time. That is, the driving motor 104 drives the driven gear 209 through the driving gear 105 to drive the driving hollow rotating part 208, the vertical connecting plate 210, the driven hollow rotating part 207, the casting mold shell bearing plate 211, and the casting mold shell placement groove 212 to rotate. When the cast wax mold shell in the casting mold shell placement groove 212 rotates in a circle to the working surface of the casting mold shell unloading robot 103, the driving motor 104 stops operating, and the casting mold shell unloading robot 103 clamps (unloads) the cast wax mold shell in the casting mold shell placement groove 212 and places it on the conveyor line of the cooling equipment or the like.

[0052] The above-mentioned casting mold shell mounting robot 102 and casting mold shell unloading robot 103 operate synchronously. That is, when the casting mold shell mounting robot 102 clamps the mold shell after casting by the wax mold shell casting device 101 and places it in the casting mold shell placement groove 212, the casting mold shell unloading robot 103 clamps the cast mold shell in the casting mold shell placement groove 212 and places it on the conveyor line of the cooling equipment or the like.

[0053] In addition, the rhythmic working control mode of the above-mentioned wax mold shell casting device 101, casting mold shell mounting robot 102, casting mold shell unloading robot 103, and driving motor 104 is a conventional control technology and also a conventional device, which will not be elaborated in this application.
