An auxiliary device for unloading foundry sand after the casting is formed

Abstract

The invention provides an auxiliary device for unloading foundry sand after the casting is formed, which relates to the field of casting and includes a receiving frame and a screen basket; the inside of the auxiliary workbench is a hollow structure, and a square The sand inlet; the inner walls of the front and rear sides of the auxiliary workbench are respectively provided with a chute, and the sand storage drawer is slidably placed in the bottom of the auxiliary workbench; the receiving frame is located in the middle of the top of the auxiliary workbench, and the support frame Installed on the top of the receiving frame; the cylinder is connected to the manual control valve at the front end of the auxiliary workbench through the air pipe, and the manual control valve is connected to the external air supply pipeline; the device drives the pressure plate to move downward through the cylinder, so that the pressure plate is pressed into the receiving frame Inside the placed casting box, the casting sand inside the casting box is divided and pressed into the sieve basket, and the casting sand is screened through the sieve basket, and the large impurities contained in the casting sand are screened and separated to ensure that the casting sand can be used in later casting Effect.

Description

Technical field [0001] The present invention belongs to the field of casting techniques, and more particularly to a cast sand immovation assisted device after casting member cast. Background technique [0002] The overlay casting refers to the production of castings with casting sand. It is a long history of process. It is also the most widely used process method. In the casting casting process, the cast box is usually fixed, and the casting is completed. Co-casting sand inside the box is cleaned; casting casting sand unloading auxiliary device can be referred to CN207900214U number, which mainly includes four rectangular support legs, four of the support legs fixedly connected to a connecting rod, four The support leg is located on the two support legs of the same side together, and the upper end of the two rails is fixedly coupled with a sand box, and the two rails are slide together with two boxes, two of the two boxes. The lower side is symmetrically provided with a guide, an...

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
