At present, most of the recovered old sand and new sand are mixed manually. When batching, the raw materials are directly poured into the mixing box for mixing, or the raw materials are poured into the mixing box for mixing after other equipment is equipped in proportion, which increases the work. time, and it is easy to cause uneven mixing through a single stirring method

Description
technical field [0001] The invention relates to the field of mold manufacturing, in particular to a mixing and stirring device for recycling and reusing molding sand for mold manufacturing. Background technique [0002] Sand is one of the necessary materials in the metal foundry industry. In order to avoid material waste, the molding sand needs to be recycled after the casting is formed and demolded; in order to ensure the quality of the molding sand mold when it is reused, it is usually necessary to recycle the sand to meet the production needs. The old sand is mixed with new sand in a certain proportion, and then used again. At present, most of the recycled old sand and new sand are mixed and mixed manually. When batching, the raw materials are directly poured into the mixing box for mixing, or the raw materials are poured into the mixing box for mixing after other equipment is proportioned, which increases the operation. time, and it is easy to cause uneven mixing by a s...
