When a mechanism is referred to as being "fixed to" another mechanism, it may be directly on the other mechanism or there may also be a centered mechanism. When a mechanism is considered to be "connected to" another mechanism, it may be directly connected to the other mechanism or there may be a centered mechanism at the same time. When a mechanism is considered to be "set on" another mechanism, it may be directly set on the other mechanism or there may be a centered mechanism at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0024] like Figures 1 to 6 As shown, the utility model is a metal casting cutting device, comprising: a processing table 1, a pushing mechanism 2, a transparent dustproof plate 3, and a cutting machine 4 fixedly mounted on the processing table 1;

[0025] A supporting mechanism for supporting the metal casting is provided on the placement plate 26; the supporting mechanism consists of a cylinder 31 and a push block 32; the cylinder 31 is fixedly installed at one end of the placement plate 26, and the telescopic rod of the cylinder 31 is fixedly connected to the push block; the push block is slidably installed on the placement plate 26, and through the above-mentioned connection relationship, when clamping the workpiece to be cut, the metal workpiece is placed on the placement plate 26, and the cylinder 31 pushes the push block 32 and the fixed block on the other side of the placement plate 26 to clamp the metal workpiece to be cut on the placement plate 26.

[0026] The pushing mechanism 2 is composed of a forward and reverse motor 21, an active bevel gear 22, a passive bevel gear 23, a threaded rod 24, a threaded rod 25, and a placement plate 26; the forward and reverse motor 21 is fixedly installed on the processing table 1; the output shaft of the forward and reverse motor 21 is fixedly connected to the threaded rod 24; the active bevel gear 22 is sleeved on the output shaft; the passive bevel gear 23 is sleeved on the threaded rod 25; the active bevel gear 22 is meshed with the passive gear; the placement plate 26 is threadedly connected to the threaded rod 24; the transparent dustproof plate 3 is threadedly connected to the threaded rod 25; through the above connection relationship, when the workpiece to be cut is cut, when the output shaft of the forward and reverse motor 21 rotates, the threaded rod 24 fixedly connected thereto and the active bevel gear 22 rotate, and the active The bevel gear 22 is meshed with the auxiliary bevel gear, thereby driving the threaded rod 25 to rotate at the same time; and because the placement plate 26 is threadedly connected to the transparent dustproof plate 3; when the motor rotates forward, the placement plate 26 rotates with the threaded rod 1 24 to drive the piece to be cut to move toward the lower end of the cutting blade of the cutting machine 4, and at the same time, the transparent dustproof plate moves toward the workbench surface driven by the threaded rod 25 until the cutting chamber is closed; when the motor reverses, the placement plate 26 moves the cut metal piece away from the cutting machine 4, and at the same time, the transparent dustproof plate 3 moves upward until it reaches the exit of the cutting chamber, and the staff replaces the cut metal piece; thereby, through the above structure, the metal waste caused by the cutting of the metal cutting piece is blocked, and no harm is caused to the staff.

[0027] The lower end of the placement plate 26 is provided with a slide rail 27; the placement plate 26 is slidably connected to the processing table 1 through the slide rail 27.
