Since the gear 74 is meshed with the ring gear 75, the gear 74 drives the ring gear 75 and the operating outer ring gear 75 to rotate. Since the operating inner magnetic steel 71 and the operating outer magnetic steel 72 are magnetically attracted to each other, the operating outer magnetic steel 72 drives the operating inner magnetic steel 71 and the sealing disk 53 to rotate. When the perforation 534 is aligned with the feed hole 515, material can be added to the lower mold 12 through the spraying mechanism 5; when the perforation 534 is aligned with the water inlet hole 516, hot water is injected into the valve body 51 to clean the inside of the valve body 51; when the perforation 534 is aligned with the air inlet hole 517, air is injected into the valve body 51 to reduce the residual moisture in the valve body 51; when the feed hole 515, the water inlet hole 516 and the air inlet hole 517 are all staggered with the perforation 534, the spraying mechanism 5 stops spraying material.

[0052] The implementation principle of Example 1 is as follows: in the first step, the displacement cylinder 31 drives the lower mold 12 to move to the support seat 13; in the second step, the operating component 7 drives the sealing disk 53 to rotate, so that the perforation 534 is connected to the feed hole 515, and the spraying mechanism 5 is moved with the help of the robotic arm 4, so that the spraying mechanism 5 atomizes the material and adds it layer by layer to the lower mold 12; in the third step, the displacement component drives the lower mold 12 to reset, so that the lower mold 12 moves to the bottom of the upper mold 11; in the fourth step, the lifting cylinder 21 drives the upper mold 11 to descend, and the upper mold 11 and the lower mold 12 are combined to form the sole, the lifting cylinder 21 drives the upper mold 11 to rise and reset, and the displacement cylinder 31 drives the lower mold 12 to move to the support seat 13, and the staff takes the formed sole out of the lower mold 12.

[0053] Example 2 Reference Figure 6 and Figure 7 The difference between this embodiment and embodiment 1 is that the operating assembly 7 includes an operating block 77 , an operating spring 78 and a limiting member 79 .

[0054] Reference Figure 6and Figure 7 An operating groove 611 is defined on the circumferential surface of the stirring rod 61, with the axis of the operating groove 611 being perpendicular to the axis of the stirring rod 61. An operating block 77 and an operating spring 78 are both disposed within the operating groove 611. An operating inclined surface is defined on the side of the operating block 77 away from the bottom wall of the operating groove 611. When the operating spring 78 is in a compressed state, one end of the operating spring 78 abuts against the bottom wall of the operating groove 611, while the other end of the operating spring 78 abuts against the operating block 77.

[0055] Reference Figure 6 and Figure 7 The inner circumference of the second circular hole 531 is defined by twelve slots 532, arranged in a circular array around the axis of the second circular hole 531. Each of the twelve slots 532 is adapted to accommodate the operating block 77. The slots 532 are triangular in shape. The slots 532 are defined by two inner walls circumferentially surrounding the sealing disk 53, defining a limiting surface 5321 and a guide surface 5322. The axis of the operating slot 611 is parallel to the limiting surface 5321.

[0056] Reference Figure 6 and Figure 7 , the operating inclined surface can contact the guide surface 5322. When the operating block 77 is inserted into any one of the slots 532, one of the feed hole 515, the water inlet hole 516 and the air inlet hole 517 is connected to the through hole 534.

[0057] Reference Figure 6 and Figure 7 When the operating block 77 is inserted into the slot 532, when the operating block 77 rotates toward the limit surface 5321 of the slot 532 where it is located, the operating block 77 can drive the sealing disk 53 to rotate and adjust the position of the through hole 534; and when the operating block 77 rotates toward the guide surface 5322 of the slot 532 where it is located, the cooperation between the guide surface 5322 and the operating inclined surface causes the operating block 77 to rotate with the stirring rod 61 and disengage from the slot 532.

[0058] Reference Figure 7 The limiting member 79 is used to limit the rotation of the blocking disk 53. The limiting member 79 includes a limiting spring 791 and a limiting block 792. A mounting groove 5111 is provided on the inner wall of the blocking cavity 511 near the pre-storage cavity 512.

The limiting spring 791 is in a compressed state, with one end of the limiting spring 791 abutting against the bottom wall of the mounting groove 5111 and the other end of the limiting spring 791 abutting against the limiting block 792. The limiting block 792 is a ball bearing.

[0059] Reference Figure 7The end surface of the sealing disk 53 facing the pre-storage cavity 512 is provided with twelve limiting grooves 533. These twelve limiting grooves 533 are arranged in a circular array around the axis of the second circular hole 531. Each of the twelve limiting grooves 533 is capable of receiving a ball. When a ball is inserted into any limiting groove 533, the operating block 77 is inserted into the engaging slot 532.

[0060] The implementation principle of Example 2 is: the stirring motor 635 drives the stirring external magnet 634 to rotate. Since the stirring external magnet 634 is magnetically attracted to the stirring internal magnet 633, the stirring external magnet 634 drives the stirring internal magnet 633, the stirring rod 61 and the operating block 77. The operating block 77 rotates toward the limiting surface 5321 of the slot 532. The operating block 77 drives the sealing disk 53 to rotate, so that the through hole 534 switches to connect to any one of the feed hole 515, the water inlet hole 516 and the air inlet hole 517, or the through hole 534 is not connected to any one of the feed hole 515, the water inlet hole 516 and the air inlet hole 517. On the contrary, the stirring motor 635 drives the stirring outer magnet 634 to rotate in the opposite direction, that is, the stirring inner magnet 633, the stirring rod 61, the stirring blade 62 and the operating block 77 rotate in the opposite direction, and the operating block 77 rotates toward the guide surface 5322 of the slot 532 where it is located. The operating block 77 is guided by the guide surface 5322 and moves toward the bottom wall of the operating slot 611, so that the operating block 77 is disengaged from the slot 532, and the stirring blade 62 performs a stirring action.

[0061] Example 3 Reference Figure 8 and Figure 9 The difference between this embodiment and embodiment 1 is that the operating assembly 7 further includes an operating block 77 , an operating spring 78 and a limiting member 79 .

[0062] Reference Figure 8 and Figure 9 An operating groove 611 is defined on the circumferential surface of the stirring rod 61, with the axis of the operating groove 611 being perpendicular to the axis of the stirring rod 61. An operating block 77 and an operating spring 78 are both disposed within the operating groove 611. An operating inclined surface is defined on the side of the operating block 77 away from the bottom wall of the operating groove 611. When the operating spring 78 is in a compressed state, one end of the operating spring 78 abuts against the bottom wall of the operating groove 611, while the other end of the operating spring 78 abuts against the operating block 77.

[0063] Reference Figure 8 and Figure 9 The inner circumference of the second circular hole 531 is defined by twelve slots 532, arranged in a circular array around the axis of the second circular hole 531. Each of the twelve slots 532 is adapted to accommodate the operating block 77. The slots 532 are triangular in shape. The slots 532 are defined by two inner walls circumferentially surrounding the sealing disk 53, defining a limiting surface 5321 and a guide surface 5322. The axis of the operating slot 611 is parallel to the limiting surface 5321.

[0064] Reference Figure 6 and Figure 7 , the operating inclined surface can contact the guide surface 5322. When the operating block 77 is inserted into any one of the slots 532, one of the feed hole 515, the water inlet hole 516 and the air inlet hole 517 is connected to the through hole 534.

[0065] Reference Figure 8 and Figure 9 When the operating block 77 is inserted into the slot 532, when the operating block 77 rotates toward the limit surface 5321 of the slot 532 where it is located, the operating block 77 can drive the sealing disk 53 to rotate and adjust the position of the through hole 534; and when the operating block 77 rotates toward the guide surface 5322 of the slot 532 where it is located, the cooperation between the guide surface 5322 and the operating inclined surface causes the operating block 77 to rotate with the stirring rod 61 and disengage from the slot 532.

[0066] Reference Figure 9 The limiting member 79 is used to limit the rotation of the blocking disk 53. The limiting member 79 includes a limiting spring 791 and a limiting block 792. A mounting groove 5111 is provided on the inner wall of the blocking cavity 511 near the pre-storage cavity 512. The limiting spring 791 and the limiting block 792 are both located in the mounting groove 5111. The limiting spring 791 is in a compressed state, with one end of the limiting spring 791 abutting against the bottom wall of the mounting groove 5111 and the other end of the limiting spring 791 abutting against the limiting block 792. The limiting block 792 is a ball bearing.

[0067] Reference Figure 9 The end surface of the sealing disk 53 facing the pre-storage cavity 512 is provided with twelve limiting grooves 533. These twelve limiting grooves 533 are arranged in a circular array around the axis of the second circular hole 531. Each of the twelve limiting grooves 533 is capable of receiving a ball. When a ball is inserted into any limiting groove 533, the operating block 77 is inserted into the engaging slot 532.

[0068] The implementation principle of Example 3 is as follows: the stirring motor 635 drives the stirring external magnet 634 to rotate. Since the stirring external magnet 634 is magnetically attracted to the stirring internal magnet 633, the stirring external magnet 634 drives the stirring internal magnet 633, the stirring rod 61 and the operating block 77. The operating block 77 rotates toward the limiting surface 5321 of the slot 532. The operating block 77 drives the sealing disk 53 to rotate, so that the through hole 534 switches to connect to any one of the feed hole 515, the water inlet hole 516 and the air inlet hole 517, or the through hole 534 is not connected to any one of the feed hole 515, the water inlet hole 516 and the air inlet hole 517. On the contrary, the stirring motor 635 drives the stirring outer magnet 634 to rotate in the opposite direction, that is, the stirring inner magnet 633, the stirring rod 61, the stirring blade 62 and the operating block 77 rotate in the opposite direction, and the operating block 77 rotates toward the guide surface 5322 of the slot 532 where it is located. The operating block 77 is guided by the guide surface 5322 and moves toward the bottom wall of the operating slot 611, so that the operating block 77 is disengaged from the slot 532, and the stirring blade 62 performs a stirring action.
