[0031] As a technical optimization solution of the present utility model, there are two forming plates 3 assembled between the third upper die base 103 and the third lower die base 203. The two forming plates 3 are symmetrically distributed about the middle of the fin wax mold 7. The inner side of the forming plate 3 is of a semi-circular structure. The forming plates 3 assist the dividing die structure 6 in shaping the outside of the fin wax mold 7.

[0032] As a technical optimization solution of the present utility model, the fixing structure 4 includes two fixing blocks 401. Two fixing blocks 401 are fixedly connected to the third lower die base 203. The two fixing blocks 401 are respectively slidably connected to the two forming plates 3.

One end of the card block 403 facing the outside of the third upper die base 103 is provided with a groove 405, and the groove 405 is of a hexagonal structure. The setting of the fixing structure 4 can not only position the forming plates 3, but also fix the third upper die base 103, so that the third upper die base 103 and the third lower die base 203 are neatly assembled and stably connected.

[0033] When the utility model is in use, first place the first lower die base 201 on the operating table, then assemble the second lower die base 202 outside the first lower die base 201, and then assemble the third lower die base 203 outside the second lower die base 202, so that the lower die base structure 2 is quickly installed; then engage the second inner partition die 604 with the top end of the first lower die base 201, and then install the second outer partition die 603 outside the second inner partition die 604, and align the bottom end of the second outer partition die 603 with the top end of the second lower die base 202. Pass the two forming plates 3 through the two fixing blocks 401 in sequence to fix the position of the forming plates 3 so that they cannot move in the horizontal direction, and the forming plates 3 separate the first outer partition die 601 and the second outer partition die 603, so that the forming plates 3 assist the first outer partition die 601 and the second outer partition die 603 to shape the outside of the fin wax mold 7; then place a plurality of built-in blocks 8 on the top end of the second inner partition die 604, and make the plurality of built-in blocks 8 form a complete circle. Then install the first inner partition die 602 on the top end of the built-in blocks 8, and engage the ends of the plurality of built-in blocks 8 facing the center of the second inner partition die 604 with the notches on the first inner partition die 602, so that the first inner partition die 602, the second inner partition die 604 and the plurality of built-in blocks 8 are fastened together, and further make the installation of the three more firm and stable, avoiding misalignment among the three and affecting the casting of the fin wax mold 7; then install the first outer partition die 601 outside the first inner partition die 602, and then align the third upper die base 103 with the third lower die base 203 from above the lower die base structure 2, and then move the third upper die base 103 downward so that the third upper die base 103 engages with the fixing block 401. During the engagement process, when the third upper die base 103 contacts the fixing block 401, first, the outer wall of the fixing block 401 abuts against the clamping block 403 and moves in a direction away from the fixing block 401, and at the same time, the fixing block 401 abuts against the spring 404 and contracts. Continuously move the third upper die base 103 downward. When the card slot 402 on the fixing block 401 is aligned with the clamping block 403, the spring 404 resets and drives the clamping block 403 to engage with the card slot 402, so that the third upper die base 103 cannot move upward. Therefore, the setting of the fixing structure 4 can not only position the forming plate 3, but also fix the third upper die base 103, making the third upper die base 103 and the third lower die base 203 neatly assembled and stably connected; then drill through the wax injection port 5 and perform wax injection work through the wax injection port 5. The operation is convenient and simple, the material utilization rate is high, the forming rate of the mold is high, and the production efficiency is improved;After the fin wax mold 7 is cast and cooled to form, remove the first upper mold base 101, then remove the second upper mold base 102. Next, insert a hexagonal wrench into the groove 405 on the clamping block 403 and push the clamping block 403 in the direction away from the fixed block 401 so that the clamping block 403 is no longer engaged with the fixed block 401. Then take out the third upper mold base 103. Next, take out the first inner partition mold 602 upward. Then, pull multiple built-in blocks 8 in sequence towards the center of the fin wax mold 7 so that the built-in blocks 8 are no longer adhered to the fin wax mold 7. Then take out the built-in blocks 8. Then take out the fin wax mold 7. Since the number of built-in blocks 8 is large and the volume is small, the built-in blocks 8 are more flexible during disassembly. Therefore, the disassembly of the built-in blocks 8 is convenient, greatly reducing the error rate during disassembly and avoiding damage to the fin wax mold 7.
