Auxiliary device for casting sand discharge after casting forming of castings

Abstract

The invention provides an auxiliary device for casting sand discharge after casting forming of castings, and relates to the casting field. The auxiliary device comprises a receiving frame and a sievebasket, wherein the interior of an auxiliary workbench is of a hollow structure, and a square sand inlet is formed in the top of the auxiliary workbench; sliding chutes are formed in the inner walls of the front side and the rear side of the auxiliary workbench separately, and a sand storage drawer is disposed in the bottom of the auxiliary workbench in a sliding manner; the receiving frame is located at the middle position of the top of the auxiliary workbench, and a supporting frame is installed at the top of the receiving frame; and an air cylinder communicates with a manually-operated control valve at the front end of the auxiliary workbench through an air pipe, and the manually-operated control valve communicates with an external air supply pipeline. A pressing plate is driven by theair cylinder to move downward to be pressed into a casting box where the receiving frame is placed, the casting sand in the casting box is segmented and pressed into the sieve basket, the casting sandis screened through the sieve basket, large bulk impurities contained in the casting sand are screened and separated, and the casting and use effects of the casting sand in the later period are guaranteed.

Description

Technical field [0001] The invention belongs to the field of casting technology, and more specifically, relates to an auxiliary device for unloading foundry sand after castings are formed. Background technique [0002] Sand foundry casting refers to the use of foundry sand as a molding material to produce castings. It is a process with a long history and the most widely used process. In the process of sand foundry casting, a casting box is usually used to fix the sand mold. After the casting is completed, the casting The foundry sand inside the tank is cleaned; the auxiliary device for unloading foundry sand for foundry can refer to the patent CN207900214U, which mainly includes four supporting legs distributed in a rectangular shape. The two supporting legs are fixedly connected with connecting rods. The two supporting legs on the same side of the two supporting legs are jointly fixed and connected to the guide rails, the upper ends of the two guide rails are fixedly connected w...

Problems solved by technology

[0003] In order to solve the above-mentioned technical problems, the present invention provides an auxiliary device for unloading foundry sand after the casting is cast, to solve the problem that the existing similar auxiliary device for unloading foundry sand for casting usually requires manual labor when used in traditional casting boxes. Manually clean and collect the foundry sand inside the casting box, the efficiency is relatively slow, and it is easy to affect the subsequent casting efficiency, and the screening effect of the unloaded foundry sand is poor. Subsequent casting casting quality problems
