[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0019] Example

[0020] like Figure 1 and Figure 2 As shown, a casting mold for an aluminum piston includes a lower mold 12 and an upper mold 13 adapted therewith. The upper mold 13 is provided with a pouring port for pouring casting liquid. The lower mold 12 is fixedly connected to a base 11 on the side away from the upper mold 13. The base 11 is fixedly connected to a plurality of columns 14, specifically four, which are respectively located at the four corners of the lower mold 12 and the upper mold 13. The columns 14 are equipped with a liftable connecting mechanism, and the connecting mechanism is equipped with a vibrating elimination mechanism for knocking the lower mold 12 and the upper mold 13 to vibrate and eliminate bubbles in the casting liquid, and the mechanism is located on the side walls of the lower mold 12 and the upper mold 13.

[0021] Specifically, when the liftable connecting mechanism drives the elimination mechanism to move up and down, the elimination mechanism will impact the side walls of the lower mold 12 and the upper mold 13, vibrating and eliminating the bubbles inside the lower mold 12 and the upper mold 13, thereby improving the quality of the casting.

[0022] like Figure 1 As shown, the connecting mechanism includes a collar 21, which is movably mounted on the outer ring of the column 14. Each column 14 is mounted with one collar, and a lifting arm 22 is fixedly connected between every two collars 21. Each lifting arm 22 is equipped with an elimination mechanism. A lifting member 24 is fixedly connected to one side of the base 11. There are two lifting members 24, which adopt a multi-stage oil cylinder. The output end of the lifting member 24 is fixedly connected to the lifting arm 22 through a horizontal plate 23.

[0023] Specifically, when the lifting member 24 drives the transverse plate 23 to move up and down, the collar 21 and the lifting arm 22 connected to each other will move up and down together. At the same time, the eliminating mechanism installed on the lifting arm 22 will also move up and down together.

[0024] like Figure 2 As shown, the elimination mechanism includes an elimination plate 41, and a moving rod 42 is fixedly connected to the side of the elimination plate 41 away from the lower mold 12. The moving rod 42 is movably sleeved on the inner ring of the lifting arm 22, and the end of the moving rod 42 away from the elimination plate 41 is fixedly connected to a baffle 43. The diameter of the baffle 43 is larger than the diameter of the inner ring of the elimination plate 41, so that the moving rod 42 cannot be separated from it when moving in the inner ring of the elimination plate 41. An elastic member 44 is fixedly connected between the baffle 43 and the lifting arm 22. The elastic member 44 adopts a spring, so that after the force pushing the elimination plate 41 and the moving rod 42 to move disappears, the elastic member 44 will push itself back to its original position through the action of the spring.

[0025] like Figure 2 As shown, the inner ring of the elimination plate 1 41 is movably sleeved with a moving rod 2 45, and the two ends of the moving rod 2 45 are fixedly connected with a baffle 2 46 and an elimination plate 2 47 respectively. The diameter of the baffle 2 46 is larger than the inner ring diameter of the elimination plate 1 41, so that the moving rod 2 45 cannot be separated from it when it moves in the inner ring of the elimination plate 1 41, and an elastic member 2 48 is fixedly connected between the elimination plate 2 47 and the elimination plate 1 41. The elastic member 2 48 adopts a spring, so that after the force pushing the elimination plate 2 47 and the moving rod 2 45 to move disappears, the elastic member 2 48 will push itself back to its original position through the action of the spring.

[0026] like Figure 1 and Figure 2As shown, a plurality of mounting brackets 31 are fixedly connected to one side of the base 11, and the mounting brackets 31 are "L-shaped". Arch plates 32 are fixedly connected to both sides of the mounting brackets 31 close to the lifting arm 22, and interference rods 49 are fixedly connected to both sides of the elimination plate 41, and the interference rods 49 are in contact with the arch plates 32.

[0027] Specifically, during the lifting and lowering movement of the lifting arm 22, the eliminating plate 41, the moving rod 42 and the structure connected thereto will be lifted and lowered together. During the lifting and lowering movement of the eliminating plate 41, the force of the elastic member 44 will push the interference rod 49 to always move in close contact with the mounting frame 31 and the arch plate 32. When the interference rod 49 moves from the arch plate 32 to the mounting frame 31, the elastic member 44 will push the eliminating plate 2 47 to hit the side wall of the lower mold 12 or the upper mold 13 through the eliminating plate 1 41, and the setting of the elastic member 2 48 will slow down the force of the eliminating plate 2 47 hitting the lower mold 12 or the upper mold 13 to avoid damage thereto. The vibration generated by the impact will disperse and eliminate the bubbles, thereby improving the quality of the casting.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
