Description

Technical Field

[0001] This application relates to the technical field of metal casting, and more specifically, to an automatic surface sand cleaning device for sand-castings. Background Art

[0002] Sand casting refers to 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. Due to the low cost and easy availability of the molding materials used in sand casting, the manufacture of the mold is simple, and it can adapt to single-piece production, batch production, and mass production of castings. For a long time, it has been the basic process in casting production. The basic raw materials for making sand molds are foundry sand and sand mold binders. The most commonly used foundry sand is silica sand.

[0003] After retrieval, the application number: CN202223031931.7 discloses a surface sand cleaning device for sand-castings, including an operating table. Fixed rods are respectively fixedly connected above both sides of the operating table, and first pneumatic cylinders are fixedly connected below one side of the two fixed rods. In this utility model, by setting clamping plates on the operating table, after the casting is placed on the operating table, the clamping plates will clamp the casting under the push of the second pneumatic cylinder and then be lifted upward by the first pneumatic cylinder, avoiding the phenomenon that the casting will not displace when being struck by a striking rod. Moreover, a striking gasket is clamped on the striking surface of the striking rod, and the striking gasket will prevent the hard part of the striking rod from damaging the casting when the striking rod hits the casting. When it is necessary to clean the sand and gravel inside the casting, the first motor will drive it to rotate so that the opening of the casting faces downward, and then the casting can be cleaned of the sand and gravel inside by striking the casting with the upper striking rod.

[0004] In the above-mentioned utility model, it is necessary to use clamping plates to clamp the casting, which results in that during the cleaning process, some of the mold sand between the clamping plates and the casting cannot be separated, thus requiring secondary cleaning, greatly reducing the cleaning effect.

[0005] To solve the above problems, this application provides an automatic surface sand cleaning device for sand-castings. Summary of the Utility Model
