A circular ring seat 3 is fixedly provided on the working platform 1. A middle section inner mold 4 is provided on the inner side of the circular ring seat 3, and a middle section outer mold 5 is provided on the outer side thereof. The middle section inner mold 4 cooperates with the middle section outer mold 5 to form a first casting cavity 6. The outer bottom end of the middle section inner mold 4 abuts against the inner side of the circular ring seat 3. A sealing member should be provided between the circular ring seat 3 and the middle section inner mold 4. Both the middle section inner mold 4 and the middle section outer mold 5 are cylindrical structures, and the central axis of the middle section inner mold 4 is located on the central axis of the middle section outer mold 5. The middle section of the septic tank can be obtained by casting raw materials in the first casting cavity 6. The two ends of the first casting cavity 6 should be provided as parent-child joints. The opening structure is convenient for connecting and assembling the middle sections of multiple septic tanks, and ensures the overall sealing when the length of the septic tank is extended. The working platform 1 is provided with a plugging inner mold 7, and the hoisting platform 2 is provided with a plugging outer mold 8. The plugging inner mold (7) and the plugging outer mold (8) are both spherical cap structures or flat plate structures. The plugging outer mold 8 should be provided with a casting port. The hoisting platform 2 is connected to the plugging outer mold 8 by means of a hook and other components, which can drive the plugging outer mold 8 to move up and down, left and right, and forward and backward. The plugging inner mold 7 cooperates with the plugging outer mold 8 to form a second casting cavity 9. If the plugging inner mold 7 and the plugging outer mold 8 are both spherical cap structures, the head of the septic tank is obtained after the raw materials are poured in the second casting cavity 9. If the plugging inner mold 7 and the plugging outer mold 8 are both spherical cap structures, the head of the septic tank is obtained. When the plugging outer mold 8 is a flat plate structure, after pouring the raw materials in the second pouring cavity 9, the partition of the septic tank is obtained. The second pouring cavity 9 is connected with the first pouring cavity 6, the middle section inner mold 4 is connected with the plugging inner mold 7, and the middle section outer mold 5 is connected with the plugging outer mold 8 to realize the connection between the second pouring cavity 9 and the first pouring cavity 6. The raw materials are poured in the second pouring cavity 9 and the first pouring cavity 6 to obtain an integrated body. If the plugging inner mold 7 and the plugging outer mold 8 are both spherical crown structures, the integrated body is a combination of the middle section of the septic tank and the head, and the combination serves as the end of the septic tank. If the plugging inner mold 7 and the plugging outer mold 8 are both flat plate structures, the integrated body is a combination of the middle section of the septic tank and the partition, and the combination serves as the middle part of the septic tank. The integrally formed body of the section and the partition serves as the middle part of the septic tank, and the integrally formed body of the middle section and the head serves as the end part of the septic tank. The two can be assembled to form a septic tank. The middle section inner mold 4 and the middle section outer mold 5 are both detachable structures, which are convenient for removing the cast finished product. The middle section inner mold 4 and the middle section outer mold 5 are both composed of multiple parts. The multiple parts are combined for casting. When the casting is completed and the finished product is removed, the multiple parts are separated. The combination and disassembly can be completed by mechanical action. Preferably, the middle section inner mold 4 is composed of two first arc plates 10 with the same structure and two second arc plates 11 with the same structure. The width of the first arc plate 10 is smaller than the width of the second arc plate 11, so as to ensure that the middle section inner mold 4 can shrink as a whole.A first bearing seat 12 is fixedly provided on the working platform 1 at the center of the circular seat 3, the two first arc plates 10 are symmetrically distributed with the first bearing seat 12, and a first driving device 13 is provided between the first arc plate 10 and the first bearing seat 12, the first driving device 13 drives the first arc plate 10 to move toward or away from the circular seat 3, the two second arc plates 11 are symmetrically distributed with the first bearing seat 12, and a second driving device 14 is provided between the second arc plate 11 and the first bearing seat 12, the second driving device 14 drives the second arc plate 11 to move toward or away from the first bearing seat 12, before the pouring work is carried out, the two first arc plates 10 and the two second arc plates 11 are spaced apart and arranged in sequence The middle section inner mold 4 is connected to form a middle section inner mold 4. When the casting is completed and the finished product needs to be taken out, the first driving device 13 first pulls the first arc plate 10 to move toward the first bearing seat 12. After the first arc plate 10 is away from the second arc plate 11 and close to the first bearing seat 12, the second driving device 14 pulls the second arc plate 11 to move toward the first bearing seat 12, so as to realize the disassembly and contraction of the middle section inner mold 4, so as to facilitate the removal of the cast finished product. When casting, the second arc plate 11 should be moved first, and then the first arc plate 10 should be moved. In order to ensure the sealing of the connection between the first arc plate 10 and the second arc plate 11, further, the first arc plate 10 has first protrusions 15 integrally formed on both sides, and the second arc plate 11 has first protrusions 15 integrally formed on both sides.
