Sand box overturning device

Abstract

The invention discloses a sand box overturning device comprising a base, a mounting seat, two rails, a sand box and a collecting bin. The right end of the mounting seat and the base are hinged througha hinged shaft. The left end of the mounting seat is not connected with the base. The rail is fixed to the mounting seat. Two rows of idler wheels which are in sliding fit with the two rails correspondingly are arranged at the bottom of the sand box. Protruding strips parallel to the rails are formed in the two side walls of the sand box. Hook plates suitable for being matched with the protrudingstrips are fixed to the left side and the right side of the mounting seat. The hook plates are of 7-shaped structures formed by connecting vertical plate parts and horizontal plate parts. When the sand box moves to the rails, the horizontal plate parts are located above the protruding strips, and gaps are formed between the horizontal plate parts and the protruding strips. The collecting bin is arranged on the left side of the base. A cover plate is arranged on the upper portion of the collecting bin in a covering mode. Sand passing holes are formed in the cover plate. A driving device is arranged on the lower portion of the mounting seat. According to the sand box overturning device, the structure is reasonable, the labor intensity can be reduced advantageously, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a sand box overturning device, in particular to a sand box overturning device for a pouring workshop. Background technique [0002] Steel sand embedded casting production process: After putting the shell mold in the sand box, inject steel sand into the sand box, vibrate the sand box, then inject molten iron into the sand box, and pour the molten iron into the shell mold. After cooling, pour out the sand in the sand box and take out the casting. In the patent document CN104308074A, a casting dry sand recycling production line is disclosed, which includes a hanging beam arranged in the workpiece unloading area and a sand box hoisting and turning mechanism arranged in the sand box emptying area. The door frame on both sides of the sand box, the sliding frame slidingly installed in the door frame and the lifting mechanism for driving the sliding frame to move upward, the two outer walls of the sand box are vertically fixed with ho...

AI Technical Summary

Problems solved by technology

When the production line is in operation, the casting is first lifted away by the door beam, and then the sliding frame is slidably installed through the door frame. The sand box is turned over, and the materials in the sand box are dumped out. When the above-mentioned sand box hoisting and turning mechanism is in operation, the operation is laborious and labor-intensive, which is not conducive to improving work efficiency.
