When the mold module reaches the pre-assembly station 1, the mold module is in a split state, the coil and the nameplate are installed on the mold module at the pre-assembly station 1, and then the mold module is conveyed by the conveying mechanism to the mold closing station 2, and the mold module is closed by the worker to form the forming cavity and the pouring port; then the mold module is conveyed to the mold heating station 3 for heating, the mold heating station 3 heats the mold module by means of the first heating bin 20, the conveying mechanism passes through the inside of the first heating bin 20, the mold module enters the first heating bin 20 along with the conveying mechanism, and the temperature in the first heating bin 20 is 190 DEG C; then the mold module is output from the first heating bin 20 to the pouring station 4, the pouring unit pours into the forming cavity of the mold module along the pouring port, the pouring material in the pouring unit is AB type two-component polyurethane sealant, and the temperature of the pouring material is 80 DEG C; after pouring is completed, the mold module enters the solidification station 5, the second heating bin 21 is arranged on the solidification station 5, the temperature in the second heating bin 21 is 160 DEG C, and after the mold module passes through the heating of the second heating bin 21, the pouring material in the forming cavity is solidified and formed; after the mold module is output from the second heating bin 21, the mold module reaches the mold opening station 6, the worker opens the mold module at the mold opening station 6, and the formed mutual inductor is taken out; the opened mold module is conveyed to the forming cavity cleaning station 7 for cleaning, so as to prevent the residual pouring material in the forming cavity or the pouring port from affecting the quality of the next mutual inductor, the forming cavity cleaning station 7 sprays the mold module by means of high-pressure airflow for cleaning; the cleaned mold module is conveyed by the conveying mechanism to the pre-assembly station 1 again to start the production of the next mutual inductor.

[0022] The utility model discloses a conveying mechanism of annular structure conveys the mold module, makes multiple mold modules pass through each station in turn, and each station is closely matched, avoids the waste of time caused by long waiting time of each station, and does not need to take down the mold module from the conveying mechanism and transfer, reduces the labor intensity of the worker, realizes the high efficiency of mutual inductor and high yield production.

[0023] Further, the conveying mechanism comprises a first universal ball table 8, a first conveying belt 9, a second universal ball table 10 and a second conveying belt 11 connected in sequence, the second conveying belt 11 is connected with the first universal ball table 8, the first universal ball table 8 is arranged at the mold closing station 2, the second universal ball table 10 is arranged at the mold opening station 6, the first conveying belt 9 passes through the mold heating station 3, the pouring station 4 and the curing station 5 in sequence, and the second conveying belt 11 passes through the forming cavity cleaning station 7 and the pre-assembly station 1 in sequence. The first universal ball table 8 is used as the mold closing workbench, and the second universal ball table 10 is used as the mold opening workbench. When the mold is closed, the mold module on the first universal ball table 8 is not automatically conveyed by the conveying mechanism, which facilitates effective mold closing and prevents the mold module from moving during mold closing, thereby ensuring the product quality of the mutual inductor. When the mold is opened, the mold module on the second universal ball table 10 is not automatically conveyed by the conveying mechanism, which facilitates quick opening of the mold module and removal of the mutual inductor. Due to the flexible rolling of the universal ball, the mold module can be flexibly shifted on the first universal ball table 8 and the second universal ball table 10 under a small force, which facilitates the workers to flexibly shift the mold module between the first universal ball table 8, the first conveying belt 9, the second universal ball table 10 and the second conveying belt 11, further reduces the labor intensity of the workers and helps to improve the production efficiency.

[0024] Further, the mold opening station 6 is provided with a trimming station 12 on one side. After the mutual inductor is removed from the mold opening station 6, the worker directly puts the mutual inductor into the trimming station 12, and the worker at the trimming station 12 trims the surface of the mutual inductor. After trimming, the mutual inductor can be boxed. The mutual inductor does not need to be transported to other positions for trimming treatment, which further improves the work efficiency and improves the space utilization rate in the production workshop.

[0025] Further, the mold module comprises a tray 13, a mold part 14 arranged on the tray 13 and a fastening bolt. The tray 13 is arranged on the conveying mechanism and conveyed by the conveying mechanism. The mold part 14 is fixed by the fastening bolt and forms a forming cavity and a pouring port. The mold part 14 and the fastening bolt are placed on the tray 13 and move synchronously through each station. The mold part 14 and the fastening bolt do not need to be disassembled and transported, which facilitates mold opening and closing and effectively prevents parts from being lost.

[0026] Furthermore, the casting unit includes a slurry storage tank 15, a slurry delivery pipe 16, a mixing head 17, and a guide rail assembly. The slurry storage tank 15 is connected to the mixing head 17 via the slurry delivery pipe 16. The mixing head 17 is mounted on the guide rail assembly and communicates with the casting port of the mold module. An electric heating wire is wound around the slurry delivery pipe 16. The slurry delivery pipe 16 delivers the casting material from the slurry storage tank 15 to the mixing head 17 for mixing. After the casting material is mixed in the mixing head 17, the mixing head 17 injects the casting material into the molding cavity of the mold module. The electric heating wire wound around the slurry delivery pipe 16 heats the slurry delivery pipe 16, maintaining good fluidity of the casting material within it. In this embodiment, the electric heating wire heats the slurry delivery pipe 16 to a temperature of 80°C. The mixing head 17 moves via the guide rail assembly, facilitating connection and separation from the mold module.

[0027] Preferably, the guide rail assembly includes an X-axis guide rail 18, a Y-axis guide rail 22, and a Z-axis guide rail 19 that form a guiding fit with each other. The mixing head 17 has degrees of freedom to move along the X-axis, Y-axis, and Z-axis respectively by means of the X-axis guide rail 18, Y-axis guide rail 22, and Z-axis guide rail 19. Figure 2 As shown, the X-axis guide rail 18 is arranged parallel to the first conveyor belt 9, and the Y-axis guide rail 22 is fixed to the ground by means of a bracket. The two sides of the X-axis guide rail 18 are respectively connected to the Y-axis guide rail 22 to form a guiding engagement. The Z-axis guide rail 19 is set on the X-axis guide rail 18 and forms a guiding engagement with the X-axis guide rail 18. The mixing head 17 is set on the Z-axis guide rail 19 and forms a guiding engagement with the Z-axis guide rail 19. The mixing head 17 has the freedom of lifting and lowering by means of the Z-axis guide rail 19, and the mixing head 17 has the freedom of translation along the X-axis by means of the engagement between the Z-axis guide rail 19 and the X-axis guide rail 18. With the cooperation of the X-axis guide rail 18 and the Y-axis guide rail 22, it has the freedom to translate along the Y-axis. When the mixing head 17 pours into the molding cavity of the mold module, it can move synchronously with the mold module along the X-axis guide rail 18. After the mold module is finished pouring, the mixing head 17 moves up along the Z-axis and separates from the mold module. The mixing head 17 moves back along the X-axis and is above the next mold module. The mixing head 17 moves along the Y-axis and connects with the pouring port of the mold module to start pouring. The cooperation between the mixing head 17 and the guide rail assembly does not require the mold module to wait in place, which further improves production efficiency.
