Problems solved by technology
[0003] Usually, after the sand casting is completed, after the casting is taken out, a large amount of molding sand will be bonded to the surface of the casting, and the casting needs to be shaken out before it can be used. The traditional shakeout process is to put the casting into the shakeout device , to vibrate and clean the castings. This method will cause the castings to collide when the sand falls out, which is easy to be damaged and affects the yield of the castings.

The invention relates to the field of casting processing, in particular to a shakeout treatment process after sand casting, which uses a shakeout treatment device. The shakeout treatment device includes a shakeout tank and a fixing frame, and one side of the shakeout tank is fixed A movable table is connected, and a movable slot is opened in the movable table, and a movable block is inserted in the movable slot, and a tooth groove is opened on one side of the movable block, and there is a No. 1 gear meshed with the tooth groove, and the No. 1 gear is an incomplete gear structure. The inside is fixedly connected with a rotating motor, one side of the shakeout tank is provided with a through groove, and an inner tank is inserted in the shakeout tank, one side of the inner tank runs through the through groove and is fixedly connected with the movable block, and the inner side of the inner tank is fixedly connected symmetrically There are several No. 1 hydraulic cylinders. The output ends of the No. 1 hydraulic cylinders are all fixedly connected with a fixed plate, and both ends of the fixed plate are symmetrically fixedly connected with brackets, and fixed wheels are inserted between the brackets. The invention can perform non-destructive Shakeout, and the shakeout effect is good, suitable for promotion.
Description
technical field [0001] The invention relates to the field of casting processing, in particular to a sand-shaking treatment process after sand casting is formed. Background technique [0002] In the field of casting processing, the commonly used casting method is sand casting, which is generally used for steel, iron and most non-ferrous alloy castings. The process is simple and easy to operate, and the molding materials are cheap and easy to obtain. It has always been the basic process in casting production. [0003] Usually, after the sand casting is completed, after the casting is taken out, a large amount of molding sand will be bonded to the surface of the casting, and the casting needs to be shaken out before it can be used. The traditional shakeout process is to put the casting into the shakeout device , to vibrate and clean the castings. This method will cause the castings to collide when the sand falls out, which is easy to be damaged and affects the yield of the cast...
