Large-size sand box

Abstract

The invention discloses a large-size sand box. The large-size sand box comprises a bottom plate, longitudinal side plates, transverse side plates and separation plates, wherein the bottom plate, the longitudinal side plates and the transverse side plates are mutually and fixedly connected to form a box body; each longitudinal side plate comprises a longitudinal groove strip body, a longitudinal sub side plate I and a longitudinal sub side plate II; the cross section of each longitudinal groove strip body is in a concave shape; two walls of a groove of each longitudinal groove strip body are respectively and fixedly connected with each longitudinal sub side plate I and each longitudinal sub side plate II so that an opening of the groove of each longitudinal groove strip body points into the box body; the separation plates are arranged in the grooves of the longitudinal groove strip bodies of the two longitudinal side plates so that the space in the box body is separated into two transverse parts; the grooves of the separation plates and the longitudinal groove strip bodies are detachably and fixedly connected. The large-size sand box is convenient to use and high in utilization rate; the large-size sand box can be used for producing a single large-size casting, but can also be used for producing a plurality of middle-size and small-size castings.

Description

technical field [0001] The invention relates to a fixing device for a casting mold used in casting production, in particular to a large sand box. Background technique [0002] The sand box is a fixing device for fixing the casting mold in the foundry production. It is generally made of metal and used to fix the sand mold after tamping. The currently used sand boxes, because the height and length of the castings vary greatly, each sand box is only for a specific size of the casting product, and some sand boxes are used because of the small batches and small batches of certain castings. After two times, it was left idle for a long time. There are many types of sandboxes used by multi-variety casting manufacturers, the manufacturing cost is high, and the area is large, the stacking management is cumbersome, and the utilization rate is very low. The backlog wastes resources and occupies the factory space. Especially the sand boxes used for large-scale castings have a large vol...

Problems solved by technology

The currently used sand boxes, because the height and length of the castings vary greatly, each sand box is only for a specific size of the casting product, and some sand boxes are used because of the small batches and small batches of certain castings. After two times, it was left idle for a long time. There are many types of sandboxes used by multi-variety casting production enterprises, the manufacturing cost is high, and the area is large, the stacking management is cumbersome, and the utilization rate is very low. Backlog, wasting resources and occupying factory space

In particular, the sand boxes used for large-scale castings have a large volume and occupy a large area when stacked. When only small or medium-sized castings are produced but not large-scale castings, the production space is reduced, which hinders normal production and is inconvenient to use.

[0003] Although there is an assembled sand box at present, only one sand box can be assembled. The operation is cumbersome and inconvenient to use. It can only be used to cast a single casting. It cannot be flexibly combined to produce multiple castings at the same time according to the needs of castings of different specifications. The utilization rate of the sand box is low. , inconvenient to use
