Mixing and stirring device for recycling molding sand for mold manufacturing

Abstract

The invention discloses a mixing and stirring device for recycling molding sand for mold manufacturing. The mixing and stirring device comprises a base, a stirring and mixing cylinder is arranged on the base, a discharging pipe is arranged at the bottom of the stirring and mixing cylinder, a feeding pipe in butt joint with the discharging pipe is arranged at the bottom of the discharging pipe, anda feeding auger is arranged in the feeding pipe; a top cover is arranged at the top of the stirring and mixing cylinder, a multi-shaft synchronous mixing and stirring mechanism extending into the stirring and mixing cylinder is arranged on the top cover, an up-and-down material turning mechanism is arranged in the stirring and mixing cylinder, a bracket is arranged on the base, and a first weighing module and a second weighing module are arranged on the bracket; and the first weighing module is provided with a recycled molding sand bin, the second weighing module is provided with a newly-generated molding sand bin, and the top cover is provided with a recycled molding sand feeding pipe and a newly-generated molding sand feeding pipe. According to the mixing and stirring device, recycled molding sand and new molding sand are fully mixed, so that a molding sand mold made of mixed sand meets the production demand.

Description

technical field [0001] The invention relates to the field of mold manufacturing, in particular to a mixing and stirring device for recycling molding sand used in mold manufacturing. Background technique [0002] Sand is one of the necessary materials in the metal casting industry. In order to avoid material waste, the molding sand needs to be recycled after the casting is molded and demolded; when it is used again, in order to ensure the quality of the molding sand mold and meet the production needs, it is usually necessary to recycle the recycled sand. The old sand and new sand are mixed according to a certain ratio, and then used again. 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 mixin...

Problems solved by technology

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
