Large-scale metal part precision casting sand treatment equipment

Abstract

The invention relates to large-scale metal part precision casting sand treatment equipment. The equipment comprises a fixing frame, a motor box, a stirring assembly, a supporting frame, a beating assembly, a water spraying plate, a connecting water pipe and a notch, wherein the stirring assembly is arranged above the fixing frame, one end of the stirring assembly is connected with the motor box, the motor box is welded to the top of the fixing frame, a driving motor is arranged in the motor box through a motor fixing frame, the supporting frame is welded to the top end of the fixing frame, the water spraying plate is arranged on the inner side of the supporting frame, a water inlet of the water spraying plate is connected with the connecting water pipe, a reinforcing plate is welded to the middle of the supporting frame, the beating assembly is arranged at the bottom of the reinforcing plate, and the notch is formed in the joint between the inner part of the fixing frame and the beating assembly. According to the equipment, circular through holes in the stirring assembly can beaten and cleaned intermittently, so that the circular through holes cannot be blocked, impurities are discharged more smoothly, resin sand is stirred more dispersedly, and the cleaning of the resin sand is facilitated.

Description

technical field [0001] The invention relates to the technical field of molding sand processing equipment, in particular to a type of precision casting molding sand processing equipment for large metal parts. Background technique [0002] At present, the foundry industry is still dominated by ordinary green sand casting, and the quality of molding sand has a direct and important impact on castings. Molding sand is generally made by mixing molding materials such as raw sand for casting, molding sand binder and auxiliary additives in a certain proportion. Molding sand can be divided into clay sand, water glass sand, cement sand, resin sand, etc. according to the different binders used. Resin sand refers to molding sand or core sand that uses synthetic resin as a binder for sand grains. After the mold or core is made of resin sand, the resin undergoes an irreversible cross-linking reaction and solidifies through the action of the curing agent, thus giving the mold or core the ...

AI Technical Summary

Problems solved by technology

[0003] However, the molding sand processing equipment in the current market has the following problems during use: a. The traditional molding sand processing equipment all adopts drum-type stirring and cleaning equipment, and during the long-term working process of the drum, the circular through-hole on the drum is easily damaged Blocking, on the one hand, affects the discharge of impurities in the resin sand, on the other hand, the drum needs to be cleaned regularly, which brings unnecessary troubles to the operator; b. The resin sand inside the drum is easy to accumulate during the operation of traditional molding sand processing equipment Together, the contact between it and the cleaning water is not sufficient, resulting in any residual impurities inside the resin sand, which affects the quality of the molding sand
