[0002] A rotary centrifugal gravity die casting machine is a type of equipment used in the casting process. It is primarily used to manufacture large, heavy, and complex metal parts. These parts are typically die-casted using gravity to assist the die casting process.

[0003] Among existing casting equipment, gravity die-casting machines are the most common. They utilize the force of gravity to shape molten metal into a predetermined shape through a die. However, when the die is ejected from existing gravity die-casting machines, the molten metal in the die rapidly cools and solidifies. This can cause the die to be impacted, leading to cracking or deformation. Therefore, we propose a new type of rotary centrifugal gravity die-casting machine to address this issue.

A mold cavity 207 is provided in the middle of the workbench 4. The mold cavity 207 is two circular hollow shapes.

[0024] The ball screw 202 at the output end can be driven by the servo motor 201 electric spindle to lift, slide, and move up and down, while the screw nut 203 remains stationary. It is composed of a standard screw nut pair, a guide rod 205, a servo motor 201, and a lower positioning mounting plate 204. The mechanism is relatively simple and can reduce impact when lifting, lowering, and jacking.

[0025] like Figure 3 、 Figure 4 As shown, the pushing mechanism 5 includes a fixed seat 501, a first oil cylinder 503, a first guide column 502 and a push plate 504.

The first oil cylinder 503 used can drive the first guide column 502 at the output end to achieve horizontal movement, so that the casting component on the inner wall can be pushed by the push plate 504 on the end of the first guide column 502. At the same time, the second oil cylinder 603 used is larger than the first oil cylinder 503 and realizes the lifting function. It can push the second guide column 604 downward to complete the push of the second top plate 606, thereby completing the die-casting operation of the casting component.
