Example Embodiment

[0014] The present invention will be further described in detail below through the examples, which are only used to illustrate the present invention and do not limit the scope of the present invention.

[0015] like figure 1 , a turning device for a foundry flask of the present invention shown in 2 includes a flask 1, a rotating shaft 2 arranged on the middle of both sides of the flask 1 and a support frame 5 arranged on both sides of the flask 1. A support groove 4 is provided in the middle of the upper end of the frame 5, and the support groove 4 is arc-shaped. The balls 3 are evenly arranged in the support groove 4, and the end of the rotating shaft 2 is set on the support groove 4 and is slidably connected to the support frame 5 through the ball 3. The diameter of the rotating shaft 2 can be changed according to production needs, and its diameter should not be larger than the support groove. The diameter of the groove 4, the balls 3 in the supporting groove 4 can also be ...

Abstract

The invention discloses an overturning device for casting a sand box. The overturning device comprises the sand box, rotating shafts arranged at the middle portions of the two side faces of the sand box, and supporting frames arranged on the two sides of the sand box. Supporting grooves are formed in the middle portions of the upper ends of the supporting frames. Balls are evenly arranged in the supporting grooves. The end portions of the rotating shafts are arranged in the supporting grooves and are in sliding connection with the supporting frames through the balls. Hydraulic columns and a hydraulic pump are arranged at the bottom of the sand box. The hydraulic lifting columns are used for overturning the sand box, corresponding procedures can be finished on the supporting frames without swinging of a traveling crane in the overturning process, the overturning process is stable, controllable and safe, the quality of a sand mould is guaranteed, and accordingly the quality of a casting is ensured. When a worker conducts operation, the hydraulic pump is driven to run by controlling a button, so that ascending and descending of the hydraulic lifting columns are achieved, then the sand box is driven to ascend and descend, the labor force of the worker is greatly relieved, the worker is safer, more comfortable and faster in the operation process, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the field of foundry sand boxes, in particular to a turning device for a foundry sand box. Background technique [0002] Casting is the process of smelting metal into a liquid that meets certain requirements and pouring it into a mold, cooling, solidifying, and cleaning to obtain a casting with a predetermined shape, size, and performance. The casting blank is almost formed, and can meet the requirements without mechanical processing or a small amount of processing, which can reduce costs and reduce processing time to a certain extent, and improve processing efficiency; in the casting production process, it is often necessary to turn over the shaped sand box repeatedly , in order to process such as coating, cleaning and core dropping. At present, the total weight of iron sand boxes and molding sand used in the production of large castings in the foundry industry is tens of tons or even hundreds of tons. On the ground or with ...
