Description

Technical Field

[0002] Sand mold usually refers to the casting cavity made of raw sand, binder and other auxiliary materials in the casting production process. Casting production requires the use of molds and molding sand to shape the casting contour. According to production needs, the position of complex shapes cannot affect the demolding, and manual placement of live blocks is required for shaping. However, manual shaping and repairing cannot guarantee the position and size accuracy of the sand mold, which often affects the quality of the product, resulting in the scrapping of castings and irreversible losses.

[0003] In recent years, with the further development of relevant technologies, the application number of the prior art is 202222428378.4, and the authorized patent of the subject name "A sand mold grinding device for casting" proposes "through the coordinated use of a moving block, a second hydraulic cylinder, an electric slide and a moving plate, so that the second hydraulic cylinder drives the moving block and the grinding disc to move forward and backward, and the output end of the electric slide drives the moving plate and the grinding disc to move left and right". However, in the actual casting production process, the direction in which the sand mold needs to be polished is not limited to the horizontal straight line direction, and for non-standard parts or special-shaped parts, the required polishing method tends to be manual and flexible. However, the polishing device provided by the prior art is limited by its own transmission structure, and manual operation is no longer possible.

[0076] As for the use height of the grinding stone component 7, the nuts at both ends of the constrained threaded rod 52 can be removed first, and the constrained threaded rod 52 can be moved out from the two square support rods 51 and the grinding bracket 4, and the second brake servo motor inside the second screw transmission component 16 can be started. The second brake servo motor drives the second screw to rotate synchronously, and then the second brake servo motor is engaged with the second nut for transmission, so that the second nut drives the grinding bracket 4 and the mounting sleeve 6 and the grinding stone component 7 associated with the grinding bracket 4 to automatically rise and fall until they are in the appropriate position.
