The feeding mechanism of this counter-gravity casting machine can be combined with a bracket with a controller at the bottom of the hopper, and the controller can be used to stir the outer frame at the bottom position, so that the controller drives the material leveling rod to move in the outer frame, so that the materials fall out from the inside of the material leveling pipe respectively, thereby increasing the feeding speed and the material leveling effect, avoiding material blockage, increasing smoothness, and ensuring the stability of the counter-gravity casting machine.

[0004] However, when feeding, the existing counter-pressure casting machine is prone to deviation between the feed port and the feed port, which may cause leakage during feeding, resulting in logistics waste, and requires cleaning, making feeding inconvenient; therefore, it does not meet existing needs. In this regard, we have proposed a counter-pressure casting machine for the production of aluminum alloy impellers that is easy to feed. Utility Model Content

The utility model arranges a center column inside the feed cavity, arranges a positioning column inside the center column, the outer wall of the positioning column has an external thread, and one end has a limiting chassis, the positioning column is threadedly connected to the connecting ring through the external thread, so that the positioning column can move up and down, after the material receiving seat is rotated to the lower end of the feed seat, the limiting chassis is driven to move downward by the rotation of the positioning column, and passes through the central material discharge port of the lower base to enter the inside of the material receiving seat, so that the feed seat and the material receiving seat are aligned, and then the positioning column is rotated to drive the limiting chassis to move up and contact with the lower end of the center column to achieve a limiting effect. At this time, the positioning column cannot be turned, which serves as a reminder. There is no need to continue turning the positioning column. The material is poured into the feed chamber and falls along the feed chamber to the lower base.

[0026] Also includes:

[0027] A feed cavity 8 is arranged inside the feed seat 3, a center column 5 is arranged inside the feed cavity 8, and a positioning column 6 is arranged inside the center column 5;

A central discharge port 11 is provided at the center of the lower base 10, and the central discharge port 11 passes through the lower base 10.

[0029] The limiting chassis 17 is driven downward by rotating the positioning column 6, passing through the central discharge port 11 of the lower base 10 and entering the material receiving seat 2, thus ensuring that the feeding seat 3 and the material receiving seat 2 are aligned, and then the positioning column 6 is rotated to drive the limiting chassis 17 to move up and contact the lower end of the central column 5, and then stop rotating, pour the material into the feeding cavity 8, and fall onto the lower base 10 along the feeding cavity 8, and rely on the inclined surface 12 to realize the flow of the material to the central discharge port 11, so that it falls into the material receiving seat 2 through the central discharge port 11, completing the feeding, and there will be no leakage, and there is no need to clean the edges, which improves the convenience of feeding and solves the problem that the discharge port and the feeding port of the counter-pressure casting machine are prone to deviation when feeding, which leads to leakage during feeding, resulting in logistics waste, and the need for cleaning, and inconvenience in feeding.

[0030] See also Figure 2 , 3 A connecting ring 7 is provided on the upper surface of the center column 5, and an external thread 15 is provided on the outer wall of the positioning column 6, and the positioning column 6 is threadedly connected to the connecting ring 7 through the external thread 15, so that the positioning column 6 can move up and down stably, and the limit chassis 17 is driven to move by the up and down movement. It is judged whether the material receiving seat 2 and the feeding seat 3 are aligned by whether the limit chassis 17 is inserted into the inside of the material receiving seat 2. After alignment, feeding can be carried out to avoid leakage.

[0031] See also Figure 2 A limiting chassis 17 is provided at the lower end of the positioning column 6, and the limiting chassis 17 and the positioning column 6 are an integrated structure. When the positioning column 6 moves upward, the limiting chassis 17 contacts the lower end of the center column 5 to play a limiting effect.

[0033] See also Figure 2 Connecting columns 9 are provided on both sides of the center column 5, and the center column 5 is fixed to the inner wall of the feed seat 3 through the connecting columns 9, so as to fix the center column 5 and the feed seat 3 to prevent the center column 5 from falling and improve stability.

[0034] See also Figure 2 , 4Bolt holes 16 are arranged around the lower base 10, and fixing bolts 13 are arranged inside the bolt holes 16. The lower base 10 is threadedly connected to the feed seat 3 through the fixing bolts 13 to fix the lower base 10.

[0035] See also Figure 1 A connecting frame 4 is provided on one side of the material receiving seat 2, and the material receiving seat 2 rotates with the casting machine body 1 through the connecting frame 4, so that the material receiving seat 2 can rotate to take out the internal products.

[0036] Working principle: When in use, one end of the positioning column 6 passes through the center column 5 from bottom to top, and the positioning column 6 is threadedly connected to the connecting ring 7 through the external thread 15 to realize the up and down movement of the positioning column 6. Before the material receiving seat 2 is rotated to the lower end of the feeding seat 3, the limiting chassis 17 of the positioning column 6 is located at the upper end of the lower base 10. After the material receiving seat 2 is rotated to the lower end of the feeding seat 3, the limiting chassis 17 is driven to move downward by the rotation of the positioning column 6, and passes through the central discharge port 11 of the lower base 10 to enter the material receiving seat 2.
