Box-closing guide device for large sand box

Abstract

The invention provides a box closing guiding device for a large sandbox. The device is used in the field of sand mold casting, and is used for solving the problems of large realization difficulty andhigh safety risk of inner box taper positioning in the molding or closing process of the large sandbox. The box closing guiding device for the large sandbox comprises a guiding rod, a first positioning piece and a second positioning piece, the first positioning piece is fixed on an upper sandbox, the guiding rod is inserted to the first positioning piece, and the second positioning piece is inserted to the guiding rod and is fixedly connected to the lower sandbox in order to realize ostensive box closing, so the safety risk of an operator in the box closing process is reduced, the efficiency of the box closing process is improved, the problem of uniform clamping of the sandbox, caused by nonalignment of positioning holes in the box edge due to torsion deformation of the upper sandbox and alower sandbox, is avoided, and the leak-out risk of metal from the sandbox is avoided.

Description

technical field [0001] The invention relates to a sand box for sand casting, in particular to a two-box positioning device for a large sand box in the box closing process. Background technique [0002] At present, in the sand casting industry, when large castings are produced by collision molding, a large sand box is used as a supporting tool. When positioning large sand boxes between boxes, if the inner box cone method is used, three operators are usually required to cooperate with the crane operator to perform precise operations in the box closing process, so as to complete the positioning of the two boxes without damaging the semi-finished product. At the same time, in order to ensure the strength of the large sand box, a wide mouth plate is used, so that there will be a certain distance between the inner box cone and the outermost side of the sand box. When closing the box, the operator needs to observe the position of the inner box cone sideways to confirm Whether the ...

Problems solved by technology

At the same time, in order to ensure the strength of the large sand box, a wide mouth plate is used, so that there will be a certain distance between the inner box cone and the outermost side of the sand box. When closing the box, the operator needs to observe the position of the inner box cone sideways to confirm Whether the two sand boxes are aligned with the preset box cone, this process not only poses a hidden danger to the personal safety of the operator, but also makes the accuracy and efficiency of the box closing not high
