Description

Technical Field

[0001] This application relates to the field of casting production equipment, and particularly relates to a sand cleaning device for a sand cleaning machine. Background Art

[0002] After the casting is poured and formed in the mold and taken out after condensation, since the mold is made by hot pressing and shaping with sand, after the casting is taken out, sand is likely to remain on the surface and inside cavity of the casting, and manual sand cleaning of the casting is required.

[0003] The existing sand cleaning method is to clean the sand through a sand cleaning machine. The casting is manually lifted to the sand cleaning machine and cleaned after being hammered by the hammer head of the sand cleaning machine. After the sand cleaning is completed, it is taken out manually again.

[0004] During the sand cleaning process of the sand cleaning machine, the casting is placed on the workbench. When the casting is hammered by the hammer head, it vibrates, and there may be a problem that the casting is displaced and the position deviates from the hammer head, and it is necessary to manually move the casting back to its position, which is inconvenient for manual operation. Utility Model Content

[0005] In order to solve the problem that when the casting is hammered by the hammer head, it vibrates and is displaced, and it is inconvenient for manual operation to move the casting back to its position, this application provides a sand cleaning device for a sand cleaning machine.

The hammering assembly includes a hammering cylinder and a hammering head. A linear driving assembly is arranged inside the box body. A slider is arranged on the linear driving assembly. The hammering cylinder is arranged at the slider. The hammering head is arranged at one end of the piston rod of the hammering cylinder. A workbench is arranged inside the box body. Clamping assemblies are arranged on opposite sides of the box body with respect to the workbench. The clamping assembly includes a pushing cylinder and a clamping member. The pushing cylinder is arranged on one side of the workbench. A pushing frame is arranged at one end of the pushing piston rod of the pushing cylinder. The pushing frame is slidably installed on the workbench. The clamping member is arranged on one side of the pushing frame.

[0008] By adopting the above technical solution, when the casting is transported to the workbench, the pushing cylinders on both sides of the workbench drive the clamping members to move, and the clamping members on opposite sides clamp both sides of the casting. The linear driving assembly drives the hammering cylinder to the upper side position of the casting, and the hammering cylinder drives the hammering head to hammer and clean the sand of the casting. During the sand cleaning, the position of the casting is fixed and it is not easy to have the problem of deviation, and the hammering and sand cleaning operation is convenient.

[0009] Optionally, the clamping member includes a first clamping plate and a second clamping plate. The first clamping plate and the second clamping plate are both disposed on the pushing frame and are oppositely arranged.
