Sand mixing device for casting processing

Abstract

The invention discloses a sand mixing device for casting processing. According to the sand mixing device for casting processing, on one hand, a stirring barrel can be separated from the sand mixing device through the cooperation among a transmission mechanism, a positioning mechanism and a locking assembly, furthermore, in the working process of mixing different types of fine sand, the stirring barrel is very convenient to clean, the cleaning effect is good, a new stirring barrel can be quickly replaced for mixing another type of fine sand, the normal operation of sand mixing work is not influenced while the cleaning effect is ensured, the sand mixing quality and the economic benefits of production and processing are ensured; and furthermore, a discharging pipe is arranged on one side of the stirring barrel, so that when the same fine sand is mixed and processed, the materials in the stirring barrel can be discharged only by opening a sealing cover, the operation is simple, and the use is convenient.

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] Casting is a kind of metal thermal processing technology mastered by humans earlier; in industrial development, casting technology is an extremely important processing technology. Casting is to melt metal into liquid, and then pour the molten metal into the mold to cool and solidify to obtain castings. ; Molding sand for casting molds is usually made of fine sand by adding a certain proportion of binder or other auxiliary materials, and then stirring and mixing evenly. [0003] For the sand mixing work in the prior art, it is usually placed in the mixing cylinder, and then the stirring rod is driven by the motor to perform the mixing and mixing work. The mixing cylinder is usually fixed, and when different types of fine sand are mixed. , it is necessary to clean the mixing cylinder, but it is v...

Problems solved by technology

[0003] For the sand mixing work in the prior art, it is usually placed in the mixing cylinder, and then the stirring rod is driven by the motor to perform the mixing and mixing work. The mixing cylinder is usually fixed, and when different types of fine sand are mixed. , it is necessary to clean the mixing cylinder, but it is very inconvenient to clean it in the prior art. The cleaning work will delay the sand mixing work and affect its work efficiency. If it is not cleaned, the remaining in the mixing cylinder The impurity fine sand will affect the mixing work of another fine sand, reduce the quality of its production, and have a negative impact on the subsequent casting work
