Demolding device for finished product formed by sand casting mold

Abstract

The invention relates to the technical field of demolding, and discloses a demolding device for a finished product formed by a sand mold casting mold. The demolding device comprises a demolding box with an opening in the upper end, and a demolding mechanism is connected to a box opening of the demolding box; and the demolding mechanism comprises a U-shaped supporting frame, the supporting frame is fixedly connected to the box opening of the demolding box, an air cylinder is fixedly connected to the top of the supporting frame, the output end of the air cylinder penetrates through the top of the supporting frame and is fixedly connected with a supporting plate, a water guide pipe is rotationally connected to the center of the supporting plate through a ball bearing, the two ends of the water guide pipe penetrate through the ball bearing and extend outwards, a pipe opening in the lower end of the water guide pipe communicates with a U-shaped spraying pipe, pipe openings in the two ends of the spraying pipe are arranged in a sealed mode, and a plurality of spraying openings are evenly formed in the pipe wall of the inner side of the spraying pipe at equal intervals. According to the demolding device for the finished product formed by the sand mold casting mold, the problems that the surface of the finished product is covered with sand during demolding at present, cleaning is very troublesome, and the surface of the finished product is damaged when cleaning is improper can be solved.

Description

technical field [0001] The invention relates to the technical field of demoulding, in particular to a demoulding device for finished products after sand casting molds are formed. Background technique [0002] Sand casting is the most commonly used method in various casting methods. After the finished product is cooled and formed in sand casting, it needs to be demolded.
