Sand mixer for casting machining

Abstract

The invention discloses a sand mixer for casting machining. The sand mixer for casting machining comprises a sand bin, a sand-mixing stirring chamber, a mixture pumping mechanism, a material transporting arm and a material unloading device. The sand bin communicates with the sand-mixing stirring chamber, the material unloading device communicates with an outlet of the sand-mixing stirring chamber, the mixture pumping mechanism is led into the position above the sand-mixing stirring chamber, and the material transporting arm is located between the sand-mixing stirring chamber and the material unloading device; the material transporting arm is rotatably connected with a base and driven to pitch through a pitch driving mechanism, and the sand bin, the sand-mixing stirring chamber, the mixture pumping mechanism, the material transporting arm and the material unloading device are all arranged on the base; and the base is rotatably connected to the position above a rack through a slewing mechanism, and a walking mechanism is arranged at the bottom of the rack. According to the sand mixer for casting machining, three-dimensional motions of the sand mixer is achieved through cooperation of the slewing mechanism, the material transporting arm being capable of pitching and the walking mechanism, therefore the material unloading position can be selected randomly, the motions are flexible, manual movement is reduced, the labor amount of workers is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to sand mixer equipment for casting, in particular to a sand mixer for casting. Background technique [0002] The sand mixer is a device that uniformly mixes the components in the molding sand and effectively coats the binder on the surface of the sand grains. Sand mixer is a kind of sand processing equipment widely used in the foundry industry. According to the characteristics of sand mixing process, sand mixer can be divided into: roller type sand mixer mainly for rolling and rubbing; Blade-type sand mixer with main function; countercurrent or rotor-type sand mixer with rubbing and mixing functions, and balance wheel sand mixer with rolling and mixing functions. [0003] The grinding wheel sand mixer uses the relative movement of the grinding wheel and the grinding plate, and crushes the material placed between the two by rolling and grinding. The edge of the traditional grinding wheel sand mixer is set on one side of the grind...

Problems solved by technology

But the technical scheme of this invention just pumps into resin and solidifying agent before casting sand is sent into stirring device, therefore, its mixing effect is not good
