Sand box with convenience in taking sand lump

Abstract

The invention discloses a sand box with convenience in taking sand lump. The sand box is of isosceles trapezoid shape; the sand box is composed of a front sand box plate, a rear sand box plate and two lateral sand box plates; a separating plate capable of sliding back and forth along the two lateral sand box plates is arranged in the sand box; and wedge blocks matched with the sand box plates are respectively arranged on the inner sides of the two lateral sand box plates. The sand box has the advantages that the sand box is of isosceles trapezoid shape, the wedge blocks are adopted for wedging, the sand box is wholly lifted and the sand box plates do not need to be opened after the sand lump is manufactured, the wedge blocks leaved on the sand lump are taken off and then the sand box plates on the two sides are assembled again for the next manufacturing, so that the efficiency of manufacturing the sand lump is increased. The separating plate capable of sliding back and forth is arranged for flexibly adjusting the size of the sand box, so that the sand box can meet the manufacturing size requirements of the sand lumps in various sizes.

Description

technical field [0001] The invention belongs to the field of sand boxes, and in particular relates to a sand box capable of conveniently extracting sand blocks. Background technique [0002] The traditional sand box is generally made of metal casting, including the sand box body and the lifting frame welded to the two symmetrical sides of the sand box body. The sand box body is a semi-closed box with an opening, and its internal space is used for Place the molding sand; in the production process of the assembly line, a large number of sand boxes need to be prepared to improve work efficiency, and the sand boxes are metal castings, and their prices are relatively expensive. [0003] In addition, in the existing sand mold engraving production, the sand box used to make sand blocks is a fixed structure, and the size of the sand mold produced is relatively single. In actual manufacturing applications, the adaptability to the production of sand blocks with different processing re...

Problems solved by technology

[0002] The traditional sand box is generally made of metal casting, including the sand box body and the lifting frame welded to the two symmetrical sides of the sand box body. The sand box body is a semi-closed box with an opening, and its internal space is used for Place the molding sand; in the production process of the assembly line, a large number of sand boxes need to be prepared to improve work efficiency, and the sand boxes are metal castings, which are relatively expensive

[0003] In addition, in the existing sand mold engraving production, the sand box used to make sand blocks is a fixed structure, and the size of the sand molds produced is relatively single. In actual manufacturing applications, the adaptability to the production of sand blocks with different processing requirements is insufficient.

At the same time, because the sand block and the sand box are closely attached during production, the friction between the two is large, and there is great difficulty in taking it out after the production is completed.
