[0002] A flywheel is a disc-shaped part with a large moment of inertia. It acts like an energy storage device. Its main function is to store energy and inertia outside the power stroke of the engine. It is often installed at the rear end of the engine crankshaft on various machines to store the engine's energy, overcome the resistance of other components, and facilitate engine starting. Especially the flywheel on the tractor, the role of the flywheel can be observed intuitively. When casting the flywheel, the molten metal liquid is poured into the mold base and vibrated by the vibration base, so that the cast flywheel has a better texture.

[0003] The vibration position of the currently used casting vibration base is fixed during vibration, and the vibration position of some vibration bases is single, so that the vibration impact force received by various parts is obviously different, which may affect the casting quality. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a vibration base for flywheel casting, which is designed to drive a rotating pressure plate to rotate by a driving motor. When the rotating pressure plate rotates, the lower end face contacts the inner end faces of each impact block, causing the impact block to gradually move downward. At the same time, the lifting rod and the stop block move downward, and the spring is subjected to the downward pressure of the impact block. The lower end of the spring is blocked, so that the spring is compressed to obtain a reverse thrust. After the rotating pressure plate rotates and passes the squeezed impact block, the spring extends, pushing the impact block to move upward, impacting the lower die base, thereby completing the impact on multiple parts of the lower die base.

[0005] The utility model provides the following technical solutions: a vibration base for flywheel casting, comprising a fixed base, a plurality of fixed vertical rods are distributed in a row on the upper surface of the fixed base, a fixed plate is fixedly arranged on the upper end of the fixed vertical rod, a plurality of through holes are opened on the fixed plate, a lifting rod is passed through the through hole, a spring is sleeved on the upper end of the lifting rod body, an impact block is formed on the upper end of the lifting rod, a stopper is formed on the lower end of the lifting rod, a driving motor is fixedly installed below the fixed plate, a transmission shaft is connected to the output shaft of the driving motor, and a rotating pressure plate is fixedly installed on the upper end of the transmission shaft.

[0006] Furthermore, the lower end surface of the rotating pressure plate is an arc-shaped end surface, and an arc-shaped depression is provided on the inner side of the impact block.

[0007] Furthermore, the spring is located below the impact block, and the spring is located inside the through hole and is blocked by the through hole.

[0008] Further, a support column is formed on the upper surface of the fixed base, and an inclined arrangement is adopted. A placement ring seat is formed at the upper end of the support column.

[0009] Further, a lower die base is placed inside the placement ring seat.

[0010] Further, symmetrical access grooves are formed on the inner wall of the placement ring seat.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] By designing the driving motor to rotate and drive the rotating pressure plate to rotate, when the rotating pressure plate rotates, the lower end surface contacts the inner end surfaces of the respective impact blocks, causing the impact blocks to gradually move downward. At the same time, the lifting rod and the stop block move downward, and the spring is subjected to the downward pressure of the impact block. The lower end of the spring is blocked, so that the spring is compressed to obtain a reaction force. After the rotating pressure plate rotates past the squeezed impact block, the spring extends, pushing the impact block upward to impact the lower die base, completing the multi-site impact on the lower die base.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figure 1-5 , which includes a fixed base 1. An inclined support column 2 is formed on the upper surface of the fixed base 1. The upper end of the support column 2 inclines inward to form a stable support structure. A placing ring seat 3 is formed at the upper end of the support column 2. The bottom of the placing ring seat 3 is penetrated. A lower die base 5 is placed inside the placing ring seat 3. Symmetric access grooves 4 are opened on the inner wall of the placing ring seat 3 to facilitate the removal of the cast flywheel. A number of fixed vertical rods 6 are arranged in a row on the upper surface of the fixed base 1. A fixed disk 7 is fixedly arranged at the upper end of the fixed vertical rod 6. A number of through holes 8 are opened on the fixed disk 7. A lifting rod 9 passes through the inside of the through hole 8. The lifting rod 9 can pass through the through hole 8. A spring 11 is sleeved above the rod body of the lifting rod 9. The spring 11 is below the impact block 10. The spring 11 is inside the through hole 8 and is blocked by the through hole 8. When the impact block 10 moves downward, the spring 11 will be compressed. An impact block 10 is formed at the upper end of the lifting rod 9. An arc-shaped depression is opened on the inner side of the impact block 10 to facilitate the generation of misaligned extrusion with the rotating pressing plate 15 when the rotating pressing plate 15 rotates, and the impact block 10 is pressed downward. A stop block 12 is formed at the lower end of the lifting rod 9. A driving motor 13 is fixedly installed below the fixed disk 7. A transmission shaft 14 is connected to the output shaft of the driving motor 13. A rotating pressing plate 15 is fixedly installed at the upper end of the transmission shaft 14. The lower end surface of the rotating pressing plate 15 is an arc-shaped end surface.

[0021] Working principle

[0022] When using this device, place the lower die base 5 in the placing ring seat 3, pour molten metal into the lower die base 5, and then start the driving motor 13. The driving motor 13 rotates to drive the rotating pressing plate 15 to rotate. When the rotating pressing plate 15 rotates, the lower end surface of the rotating pressing plate 15 contacts the inner end surface of each impact block 10, causing the impact block 10 to gradually move downward. At the same time, the lifting rod 9 and the stop block 12 move downward. The spring 11 is subjected to the downward pressure of the impact block 10, and the lower end of the spring 11 is blocked, so that the spring 11 is compressed. After the rotating pressing plate 15 rotates past the squeezed impact block 10, the spring 11 extends and pushes the impact block 10 upward to impact the lower die base 5, generating a certain impact force. Each impact block 10 impacts the lower die base 5 in turn.
