Description

Technical Field

[0001] The utility model relates to the technical field of mechanical casting, and more specifically to a molding sand dispersion and screening device for mechanical casting. Background Art

[0002] Casting is one of the earliest metal heat processing technologies mastered by humans, with a history of about 6,000 years. Casting refers to the processing method of melting solid metal into liquid and pouring it into a mold of a specific shape, waiting for it to solidify into shape. Ordinary casting materials are raw sand, clay, water glass, resin and other auxiliary materials. For sand materials such as raw sand, screening treatment is required.

[0003] When screening molding sand, a molding sand dispersion screening device is generally used. However, the screening structure of most existing molding sand screening devices is mostly fixed. After long-term use, fine sand is easily accumulated on the screening structure, causing blockage of the screening structure, which in turn affects the molding sand screening efficiency.

[0012] As a preferred solution of the present invention, two support frames are fixedly installed on the outer wall of the screening drum.

[0013] Beneficial effects

[0014] Compared with the prior art, the present invention provides a sand dispersion and screening device for mechanical casting, which has the following beneficial effects:

[0015] 1. In this solution, the screening plate inside the screening drum is used for screening molding sand for mechanical casting. The screening plate is connected to the universal ball through a connecting short rod. At the same time, the universal ball is movably embedded in the bottom end of the mounting rod, which is convenient for the screening plate to change its angle inside the screening drum, avoiding blockage due to the fixed screening plate, and improving the efficiency of molding sand screening.
