Detachable Universal Flask for V-shaped Rotary Castings

Abstract

The invention discloses a detachable universal sand box for V-shaped rotator castings. The detachable universal sand box comprises an upper box and a lower box. The upper box is a square sand box, the lower box is a pyramid-shaped sand box, at least two layers of square sand boxes are connected with each other in an overlaid manner to form the pyramid-shaped sand box, the lengths and the widths of each layer of square sand boxes are gradually reduced, every two adjacent layers of square sand boxes are centered and aligned with each other by the same side walls and are connected with each other by bracings, and other corresponding side walls of every layers of square sand boxes are fixedly connected with one another by bracings. The detachable universal sand box has the advantages that the multiple individual universal sand boxes are combined with one another to form the lower box, can be directly used for producing other product after the detachable universal sand box is used up and the inclined bracings are cut, and even can be manufactured from appropriate idle old boxes.

Description

technical field [0001] The invention relates to the technical field of sand casting, in particular to a detachable general-purpose sand box for V-shaped rotary castings. Background technique [0002] The sand box is an essential tool in the casting production process, and the correct design and selection of the sand box has great practical value. [0003] Usually, in order to facilitate the fastening of the box and prevent the casting from running out of fire, the outline of a set of sand boxes is the same, and they are superimposed layer by layer. However, for some V-shaped gyratory structures, that is, castings with a large top and a small trumpet shape, the use of such a conventional sand box will result in a very large sand consumption, a high sand-iron ratio, a large weight of the sand box, and an increase in cost. . At the same time, the thick sand layer of the traditional sand box is not conducive to the rapid cooling of the casting, resulting in a long production c...

Problems solved by technology

This patent has the following disadvantages: because the vertical section is an inverted trapezoidal upper box with an inverted "eight" structure, its versatility is poor, and it is generally only applicable to the casting production of V-shaped rotary castings. When the casting of the structure is used, the upper sand box of this structure is idle or scrapped
