Problems solved by technology
[0003] The sand mixer is a kind of sand treatment equipment widely used in the foundry industry. The components in the molding sand are uniformly mixed through the sand mixer, and the binder is effectively coated on the surface of the sand grains. Some existing sand mixers When the machine is mixing the materials, the mixing is insufficient and uneven, so that the quality of the subsequent products is not high
In addition, the molding sand in the casting process is often mixed with metal impurities during the recycling process. If the metal impurities are not removed, it will inevitably affect the subsequent product processing quality

The invention discloses a sand mixing device for casting. The sand mixing device for casting comprises a machine case body and a feeding hopper arranged on the top of the machine case body. A funnel-shaped material mixing cavity is formed in the machine case body and internally provided with two stirring shafts. A balance plate is connected between the two stirring shafts. V-shaped grooves are formed outside the balance plate. Magnetic strips are fixed in the V-shaped grooves. The balance plate is provided with spiral stirring blades. The two stirring shafts are connected with a support located on the outer side of the material mixing cavity. The support is connected with a servo motor installed on the machine case body. The inner wall of the material mixing cavity is provided with a plurality of grooves used for adding adhering agents. The grooves are communicated with a material belt through a guiding pipe which is provided with an adjusting valve. Arc-shaped inner grooves are further formed in the two sides of the inner wall of the material mixing cavity. Magnetic blocks are installed in the arc-shaped inner grooves. By means of the sand mixing device for casting, mixing is uniform, and the machining quality of subsequent products can be improved.
Description
technical field [0001] The invention relates to the technical field of foundry processing, in particular to a 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. Through the sand mixer, the components in the molding sand are evenly mixed, and the binder is effectively coated on the surface of the sand. Some existing sand mixers When the machine mixes the materials, the mixing is insufficient and uneven, so that the quality of the...
