Medium introduction type non-contact magnetic control type sand mixing device for casting processing

Abstract

The invention discloses an intermediate introduction type non-contact magnetic control type sand mixing device for casting processing. The device comprises a non-contact magnetic control type auxiliary sand mixing mechanism, a forward and reverse switching type internal and external reverse mixing mechanism, an inclined overturning type primary crushing feeding mechanism, a sand mixing cylinder, a plugging mechanism and a split type collecting mechanism. The invention belongs to the technical field of sand mixing for casting processing, and particularly relates to an intermediary introduction type non-contact magnetic control type sand mixing device for casting processing, according to the characteristic that molding sand is easy to adhere to the inner wall of a sand mixing cylinder during uniform mixing and cannot be removed in time, a mode of combining array type cleaning bristles and a leakage screen type uniform mixing plate is adopted, so that the sand mixing efficiency is improved; the technical effect of uniformly mixing the materials is realized, and the technical effect of cleaning the materials adhered to the inner wall of the sand mixing cylinder is also realized; by adopting a mode of combining positive and negative switching type internal and external reverse mixing and magnetic control assistance and by introducing magnetic powder as an intermediary, the technical effect of non-contact mixing of materials is realized, and the technical problem that molding sand is not thoroughly mixed is solved.

Description

technical field [0001] The invention belongs to the technical field of sand mixing for foundry processing, and particularly relates to an intermediary introduction type non-contact magnetic control type sand mixing device for foundry processing. Background technique [0002] Sand casting is a casting method that produces castings in sand. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting. Because the molding materials used in sand casting are cheap and easy to obtain, the casting mold is simple to manufacture, and can be adapted to single-piece production, batch production and mass production of castings, and has been the basic process in casting production for a long time. [0003] Sand mixer is a kind of sand processing equipment widely used in the foundry industry. It mixes the components in the molding sand evenly through the sand mixer. Some existing sand mixers do not mix the materials sufficiently and fail to mix. uniform, so that the q...

Problems solved by technology

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an intermediary introduction type non-contact magnetic control sand mixing device for casting processing, according to the fact that the molding sand is easy to adhere to the inner wall of the sand mixing cylinder when it is mixed and Due to the characteristics of not being able to be removed in time, the method of combining the array type cleaning bristles and the leaking sieve type mixing plate not only realizes the technical effect of material mixing, but also realizes the cleaning effect of the adhered material on the inner wall of the sand mixing cylinder. Technical effect: The combination of forward and reverse switching type internal and external reverse mixing and magnetic control assistance is adopted, and the technical effect of non-contact mixing of materials is realized by introducing magnetic powder as an intermediary, which solves the traditional problem of mixing in molding sand. Uniformity, incomplete mixing and uneven technical problems
