Sand mixing device for casting processing and sand mixing method thereof

Abstract

The invention discloses a sand mixing device for casting processing and a sand mixing method thereof, and belongs to the technical field of sand mold casting. The sand mixing device comprises a sand mixing mechanism, a material passing assembly is arranged at the upper end of the sand mixing mechanism, and a feeding assembly is arranged at the upper end of the material passing assembly. The sand mixing mechanism comprises a sand mixing tank and a transmission cover arranged inside the sand mixing tank. Stirring underframes are fixedly installed on the bottom side of the transmission cover at intervals, and stirring main paddles are fixedly installed at the upper ends of the stirring underframes at intervals. A motor is fixedly installed in the middle of the bottom end of the sand mixing tank, and the output end of the motor is fixedly connected with a rotating shaft. According to the sand mixing device for casting processing and the sand mixing method thereof, component materials can be conveniently subjected to pre-throwing dispersion, stirring dispersion and material separation treatment during feeding, so that the influence of the added caked component materials on the materialmixing treatment result is effectively prevented, the component materials in the sand mixing tank can be quickly and fully stirred and mixed, and the stirring and mixing treatment effect of the component materials is more uniform and thorough. The mixing treatment working efficiency of the component materials is improved, and the mixing treatment quality of the component materials can be better improved.

Description

Technical field[0001]The invention belongs to the technical field of sand casting, and specifically relates to a sand mixing device for casting processing and a sand mixing method thereof.Background technique[0002]Sand casting refers to a casting method in which castings are produced in sand. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting methods. Because the molding materials used in sand casting are cheap and easy to obtain, and the molds are easy to manufacture, they can adapt to single-piece production, batch production and mass production of castings. For a long time, it has been the basic process in casting production and the basic process of making sand molds. The raw materials are foundry sand and sand binder. The most commonly used foundry sand is siliceous sand. When the high temperature performance of silica sand cannot meet the requirements of use, special sands such as zircon sand, chromite sand, and corundum sand are used. In order to m...
