Abstract

The invention provides a sand box with a pressing device. The sand box comprises an upper sand box body and a lower sand box body, and the upper sand box body and the lower sand box body are fixed through the pressing device. The pressing device comprises an arch-shaped connecting rod, a connecting plate and a rotating screw, the connecting plate is fixed to one side of the lower sand box body, the lower end of the arch-shaped connecting rod is fixed to the connecting plate, the upper end of the arch-shaped connecting rod is located at the upper portion of the upper sand box body, and the rotating screw is rotationally connected to the upper end of the arch-shaped connecting rod. A vertical through hole is formed in the upper end of the arch-shaped connecting rod, an internal thread is formed in the through hole, and an external thread matched with the internal thread is arranged on the rotating screw.

Description

technical field [0001] The invention relates to the field of foundry tooling, in particular to a sand box with a pressing device for sand casting. Background technique [0002] Sand Casting - A casting method in which castings are produced in sand molds. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting. Because the molding materials used in sand casting are cheap and easy to obtain, the casting mold is easy to manufacture, and it can adapt to the single-piece production, batch production and mass production of castings. It has been the basic process in casting production for a long time. Usually in sand casting, the sand box is an indispensable tool. The sand box is generally made of wood. After a long time of use, it is easy to be damaged, which makes it difficult to align the upper and lower sand boxes, and it is easy to pour out scrap castings. Contents of the invention [0003] Purpose of the invention: The technical problem to be solve...
