Shakeout treatment equipment and casting shakeout treatment process for hollow castings after pouring and cooling

Abstract

The invention relates to shakeout treatment equipment for a hollow casting after pouring cooling and a casting shakeout treatment process. The shakeout treatment equipment comprises a bottom plate, two support side plates, two protection devices, a shakeout device and a cleaning device, wherein the support side plates are arranged on the upper end face of the bottom plate in a left and right symmetric mode; the protection devices are arranged on the upper end face of the bottom plate in a front and back symmetric mode; the shakeout device is arranged between the inner side faces of the supportside plates; and the cleaning device is arranged on the inner end face of the middle part of the shakeout device. The shakeout treatment equipment and the casting shakeout treatment process can solvethe problems that the surface of a casting mould is damaged due to collision between the existing shakeout machine and the casting mould, a large amount of flying dust appears in the shakeout process, the clamping for a cylindrical hollow casting is unstable during shakeout, the production of large particles of blocked molding sand cannot be effectively reduced, the inner chamber of the hollow casting is difficultly cleaned and cannot clean up, etc. The shakeout treatment equipment and the casting shakeout treatment process can realize the functions of automatic cleaning for the inner chamberand shakeout for the cylindrical hollow-chamber casting.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to equipment for sand shakeout treatment of hollow castings after pouring and cooling, and to a sand shakeout treatment process for hollow castings. Background technique [0002] In sand casting, castings after pouring and cooling must be shaken out and cleaned before they can be machined or used. Shakeout is done manually during single-piece production. In existing equipment, sand shakeout can be done during batch production. On board. After the casting is cooled, a layer of sintered sand is often bonded to the inner and outer surfaces, which needs to be cleaned. However, due to poor working conditions and low production efficiency, cleaning machines should be used instead of manual operations. [0003] The existing shakeout machine mainly uses the collision between the mold and the shakeout machine to achieve shakeout, but when the mold collides with the shakeout machine, it is e...

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a hollow casting shakeout treatment equipment and a casting shakeout treatment process after pouring and cooling, which can solve the damage to the surface of the mold caused by the collision between the existing shakeout machine and the mold, and the sandout process. A large amount of dust, unstable clamping of cylindrical hollow castings when falling sand, inability to effectively reduce the generation of large-grained agglomerated sand, and difficult and unclean cleaning of the inner cavity of hollow castings; The inner cavity of cylindrical cavity castings can be automatically cleaned and shaken out, with no collision between the shakeout machine and the mold, less dust during the shakeout process, and stable clamping of cylindrical hollow castings during sand shakeout , can effectively reduce the generation of large-grain agglomerated sand, clean the inner cavity of hollow castings, etc.
