Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, in particular to a pneumatic device for demoulding a high-temperature alloy master alloy. Background Art

[0002] During the production of high-temperature master alloys, direct casting of molten steel is often used. Molten master alloy steel in a crucible is poured into a predetermined rod mold, and then demolded to produce a high-temperature master alloy rod. During demolding, the commonly used method is to secure the rod mold and then eject the high-temperature master alloy rod using a cylinder or other power device. However, different rod molds vary, and existing demolding devices have a simple structure, making it difficult to adjust the height of the cylinder and secure rod molds of different lengths. This can prevent some high-temperature master alloy rods from being smoothly separated from the rod mold, resulting in damage to the rod mold and a reduced direct yield of the high-temperature master alloy.

[0022] in,

[0023] There are two groups of positioning mechanisms 4 , which are respectively located at the upper and lower ends of the positioning slot 11 .

[0024] One end of the C-shaped frame 1 is provided with two vertical slide grooves, and one end of the placement plate 7 is connected to two sliders adapted to the slide grooves. The sliders slide in cooperation with the slide grooves to limit the placement plate 7 when it moves up and down.

[0025] A sliding hole is provided at the other end of the C-shaped frame 1 , and the positioning rod 9 is slidably engaged with the sliding hole.

[0026] The other end of the C-shaped frame 1 is provided with two horizontal grooves, and one end of the two positioning plates 8 is connected to a sliding block, which slides in the grooves to prevent the positioning plates 8 from being misplaced.

The positioning rod 9 is rotated in the opposite direction until the rod film is clamped. At this time, the spring 10 is stretched to prevent the positioning rod 9 from rotating and causing the rod film to loosen, thereby achieving the goal of fixing rod films of different lengths. Then the driving member 5 is started to drive the threaded rod 6 to rotate, drive the placement plate 7 to move, and then drive the cylinder 2 to move.
