[0003] After the casting is completed, the surface of the casting mold needs to be cleaned and then polished. The existing casting mold cleaning method is relatively rough. The staff directly places the mold on the ground and then uses a steel brush or a harder brush to clean the sand residue attached to the inner wall of the mold. This method is not only inefficient and labor-intensive, but also because the mold is heavy and difficult to flip, the cleaned impurities are not convenient to be discharged from the inside. To this end, the present application proposes a casting mold for a reducer gear in order to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4A casting mold for a reducer gear comprises a vertical plate 1 and a mold body 2. A rotating opening 10 is provided on the vertical plate 1. A screw 11 is rotatably provided in the rotating opening 10. A driving motor 12 is installed on the upper end surface of the vertical plate 1. The output shaft of the driving motor 12 rotates through the outer wall of the vertical plate 1 and extends into the rotating opening 10 and is fixedly connected to the end of the screw 11. A limiting rod 17 is also provided in the rotating opening 10. The limiting rod 17 is parallel to the screw 11, which realizes the limitation of the nut 16 to prevent the nut 16 from rotating with the screw 11.

[0023] A nut 16 is threadedly sleeved on the screw rod 11, a connecting frame 18 is provided on the nut 16 through an insertion mechanism, the connecting frame 18 is connected to the vertical plate 1 through a disassembly mechanism, a rotating rod 15 is rotatably provided on the connecting frame 18, the rotating rod 15 is connected to the mold body 2 through a connecting mechanism, and the rotating rod 15 is connected to the vertical plate 1 through a rotating mechanism.

[0024] The plug-in mechanism includes an insert block 20 arranged on the outer wall of the nut 16, and the surface of the connecting frame 18 in contact with the nut 16 is designed to be concave, and the surface of the connecting frame 18 in contact with the nut 16 is provided with a slot 21 corresponding to the insert block 20. The above-mentioned contact surface is concavely designed to fit the outer wall of the nut 16. After the above-mentioned insert block 20 is horizontally inserted into the slot 21, the nut 16 can be raised and lowered on the screw rod 11 to drive the connecting frame 18 to rise and fall synchronously.

[0025] The disassembly and assembly mechanism includes limit grooves 19 arranged on the inner walls on both sides of the disassembly and assembly port 9, and the limit grooves 19 are arranged corresponding to the connecting frame 18. A disassembly and assembly port 9 connected to the limit grooves 19 is provided on the front of the vertical plate 1. The connecting frame 18 in this scheme has a T-shaped design in a top view, and it is combined with the limit grooves 19 to avoid horizontal movement and separation from the nut 16. Only when the connecting frame 18 moves to the position of the disassembly and assembly port 9 can it move horizontally to complete the separation operation from the nut 16.

[0026] The connecting mechanism includes a connecting plate 13 fixedly connected to the end of the rotating rod 15. The connecting plate 13 is connected to the mold body 2 through multiple bolt assemblies 14. With the help of the connecting plate 13 and multiple bolt assemblies 14, the mold body 2 can be easily disassembled and assembled relative to components such as the nut 16.

[0027] The rotating mechanism includes a rack 8 arranged on the front side of the vertical plate 1. The rack 8 is arranged corresponding to the gear 7. The gear 7 will mesh with the rack 8 only after it rises to a certain height following the nut 16 and other components. During the subsequent rising process of the gear 7, the gear 7 will rotate due to the rack 8.

[0028] A horizontal plate 3 is installed on the vertical plate 1, and an interlocking groove 4 corresponding to the horizontal plate 3 is provided on the bottom wall of the mold body 2. The horizontal plate 3 forms an L shape with the vertical plate 1, which plays a role of stable support to prevent the mold body 2 from tipping over due to unstable center of gravity after rising, and the interlocking groove 4 ensures that the mold body 2 will not be blocked by the horizontal plate 3 when it descends and touches the ground.

[0029] An auxiliary plate 5 is mounted on the vertical plate 1 , and an opening 6 corresponding to the rotating rod 15 is provided on the auxiliary plate 5 . The rotating rod 15 in this solution is a rectangular column, and after entering the opening 6 , the rotating rod 15 is restricted and will not rotate any further.

[0030] When the utility model is used, when the inside of the mold body 2 needs to be cleaned or polished, the drive motor 12 is first started, and the drive motor 12 drives the screw 11 to rotate. When the screw 11 rotates, the nut 16 on the outer wall will rise in the rotating mouth 10. The nut 16 cooperates with the gear 7, the rotating rod 15 and the connecting plate 13 to drive the mold body 2 to rise to a certain height, and the gear 7 has not yet engaged with the rack 8. After the height is raised, the operator does not need to squat on the ground to perform the above operations if he cleans or polishes the inside.

[0031] After the cleaning or grinding process is completed, the drive motor 12 continues to start, and at this time, the gear 7 and other components continue to rise until they are meshed with the rack 8. As the above components continue to rise, the gear 7 will rotate under the action of the rack 8, thereby driving the mold body 2 to rotate with the help of the rotating rod 15, so that the mold body 2 rotates and flips, thereby realizing the pouring operation of the residual waste inside, and the inside of the mold body 2 can also be cleaned when the mold body 2 is in a tilted state.

[0032] The motor 12 is then driven in reverse to realize the lowering operation of the mold body 2. When the gear 7 loses engagement with the rack 8, the mold body 2 is in a horizontal state. At this time, the rotating rod 15 enters the rotating mouth 10 and is limited by the rotating mouth 10 to prevent the rotating rod 15 and other components from shaking during the lowering process, causing the mold body 2 to be tilted.

[0033] When the driving motor 12 in this scheme continues to start, the nut 16 will eventually drive the connecting frame 18 to move to correspond to the disassembly port 9. At this time, the connecting frame 18 loses its horizontal limit, and the connecting frame 18 is moved horizontally to be removed from the disassembly port 9, thereby realizing the disassembly of the mold body 2 and other components relative to the screw 11 and other components.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
