The embodiments of this utility model will be described below based on its overall structure.

[0023] Reference Figures 1 to 6 In this embodiment of the present invention, a casting mold for aerospace metal equipment includes: a supporting base 1, which serves as the basic supporting component of the entire casting mold, providing a stable installation platform for other components and ensuring the stability of the mold during operation; an inner supporting ring 2 is fixedly connected to one end of the supporting base 1, and an outer supporting ring 3 is fixedly connected to the other end of the supporting base 1; both the inner supporting ring 2 and the outer supporting ring 3 serve as supporting components for steering.

[0024] The top of the inner ring frame 2 and the outer ring frame 3 are jointly provided with a rotating ring base 4. The rotating ring base 4 is the mounting carrier of the lower mold and rotates under the support of the inner ring frame 2 and the outer ring frame 3. The inner wall of the inner ring frame 2 and the outer wall of the outer ring frame 3 are jointly provided with an upper mold mechanism 5.

[0025] A motor 6 is fixedly connected to the other end of the support base 1 to provide power for the rotation of the rotating ring base 4. A gear 7 is fixedly connected to the output end of the motor 6 to transmit the power of the motor 6 to the rotating ring base 4, thereby realizing the rotation of the rotating ring base 4.

[0026] An installation groove 8 is provided at one end of the rotating ring base 4. A lower mold mechanism 9 is provided inside the installation groove 8. A toothed groove 10 is provided on the inner wall of the rotating ring base 4. The motor 6 drives the rotating ring base 4 through the meshing of the gear 7 and the toothed groove 10, so that the rotating ring base 4 can rotate stably and accurately. There are multiple sets of installation grooves 8 and lower mold mechanisms 9. The multiple sets of installation grooves 8 are arranged in a ring above the rotating ring base 4. There are multiple sets of toothed grooves 10. The gear 7 is matched with the toothed groove 10.

[0027] Reference Figures 1 to 4 A limiting through groove 11 is provided at one end of the support base 1. A cylinder 12 is fixedly connected to the other end of the support base 1. A limiting movable plug 13 is fixedly connected to the movable end of the cylinder 12. The limiting movable plug 13 is adapted to the limiting through groove 11. There are multiple sets of limiting through grooves 11. There are two sets of cylinders 12 and two sets of limiting movable plugs 13. The cylinder 12 pushes the limiting movable plug 13 into the limiting through groove 11 inside the support base to limit the rotating ring base 4, prevent it from shaking or shifting, ensure the stability of the mold closing and casting process, reduce casting defects caused by equipment instability, and prevent it from being unstable during operation.

[0028] Reference Figure 1 and Figure 5 The upper mold mechanism 5 includes a support frame 501, a second cylinder 502, and a connecting pressure block 503. The support frame 501 is fixedly connected between the inner support ring 2 and the outer support ring 3. The second cylinder 502 is fixedly connected to the inner side of the support frame 501. The connecting pressure block 503 is fixedly connected to the movable end of the second cylinder 502.

[0029] The upper mold 504, the inclined inlet pipe 505, and the liquid inlet 506 are connected. The upper mold 504 is fixedly connected to the bottom of the connecting pressure block 503, the inclined inlet pipe 505 is fixedly connected to the top middle of the upper mold 504, and the liquid inlet 506 is fixedly connected to the top of the inclined inlet pipe 505. The motor 6 drives the gear 7 to rotate. Due to the toothed groove 10 inside the rotating ring base 4, the rotating ring base 4 can be rotated, causing one set of lower mold mechanisms 9 on the rotating ring base 4 to be located directly below the support frame 501. Then, the cylinder 502 pushes the connecting pressure block 503 downwards, causing the connecting pressure block 503 to drive the upper mold 504 downwards, closing with the lower mold mechanism 9 to form the cavity required for casting. The liquid hopper 506 injects molten metal into the inclined inlet pipe 505. The molten metal flows along the inclined inlet pipe 505 into the cavity formed by the upper mold 504 and the lower mold mechanism 9, completing the molten metal injection process. After casting is completed, the cylinder 2 502 contracts, driving the connecting pressure block 503 and the upper mold 504 to move upward, realizing mold opening. Then, the motor 6 is started again, rotating the rotating ring base 4, rotating the lower mold mechanism 9 with the casting to the appropriate position. At the same time, the next set of prepared lower mold mechanisms 9 is rotated to the support frame 501 for mold closing and casting. This method makes the casting process form an efficient production cycle, which can quickly switch to the required lower mold mechanism 9 and realize the continuous production of products of various specifications.

[0030] Reference Figure 1 , Figure 2 , Figure 4 and Figure 6 The lower mold mechanism 9 includes a skirt frame 901, a lower mold 902, and a bolt 903. The skirt frame 901 is movably inserted into the mounting groove 8, and the lower mold 902 is fixedly connected to the inner side of the skirt frame 901. The bolt 903 is located at one end of the upper part of the skirt frame 901, and the lower mold 902 is movably inserted into the mounting groove 8. The other end of the bolt 903 passes through the skirt frame 901 and is threadedly connected to the rotating ring base 4. By loosening the bolt 903, the fixed state of the skirt frame 901 and the lower mold 902 to the rotating ring base 4 is released, and both can be removed from the mounting groove 8. In this way, without hindering casting, it is convenient to maintain, replace molds, or clean a set of lower mold mechanisms 9. This makes maintenance work more convenient and quick, without spending a lot of time and effort on disassembling the entire mold, reducing maintenance and time costs. At the same time, parallel operation further improves the utilization rate of equipment and time, and increases the output per unit time.

[0031] The working principle of this utility model is as follows:

[0032] Step 1: The motor 6 starts and drives the gear 7 to rotate. Due to the setting of the toothed groove 10 inside the rotating ring base 4, the rotating ring base 4 can be driven to rotate, so that one of the lower mold mechanisms 9 on the rotating ring base 4 is located directly below the support frame 501. Then, the cylinder 2 502 pushes the connecting pressure block 503 to move downward. The connecting pressure block 503 drives the upper mold 504 to move downward, and closes with the lower mold 902 to form the cavity required for casting. The molten metal is injected into the inclined inlet pipe 505 through the liquid inlet hopper 506. The molten metal flows into the cavity formed by the upper mold 504 and the lower mold 902 along the inclined inlet pipe 505, completing the molten metal injection process. After casting is completed, the molten metal is injected into the cavity formed by the upper mold 504 and the lower mold 902. The retraction of cylinder 502 drives the connecting pressure block 503 and the upper mold 504 to move upward, thus opening the mold. Then, the motor 6 is restarted to rotate the rotating ring base 4, which rotates the lower mold mechanism 9 with the casting to the appropriate position. At the same time, the next set of prepared lower mold mechanisms 9 is rotated to the underside of the support frame 501 for mold closing and casting. This method forms an efficient production cycle in the casting process, which can quickly switch to the required lower mold mechanism 9, realize the continuous production of multiple specifications of products, reduce equipment idle time, further improve the overall production efficiency, and meet the requirements of large-scale production. In addition, a metal liquid tank can be installed on the top of the support frame 501 for easy material feeding.

[0033] Step two: Loosen bolts 903 to release the fixed state of skirt frame 901 and lower mold 902 to rotating ring base 4, and remove them from the mounting slot 8. This allows for easy maintenance, mold replacement or cleaning of a set of lower mold mechanisms 9 without hindering casting. This makes maintenance work more convenient and faster, without spending a lot of time and effort on disassembling the entire mold, reducing maintenance and time costs. At the same time, parallel operation further improves the utilization rate of equipment and time, and increases the output per unit time.

[0034] Step 3: When the operation is performed directly below the rotating support frame 501 of the lower mold mechanism 9, the cylinder 12 pushes the limiting movable plug 13 into the limiting through groove 11 inside the support base to limit the rotating ring base 4, preventing it from shaking or shifting. This ensures the stability of the mold closing and casting process, reduces casting defects caused by equipment instability, and prevents it from being unstable during operation.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
