Description

Molding sand recycling device for casting of automobile parts

Technical Field

The application relates to the technical field of casting, especially a molding sand circulation treatment recycles device for auto-parts casting foundry goods.

Background

Sand casting refers to a casting method using molding sand for molding. The main process is as follows:

(1) and manufacturing a casting mold. The mold is made of wood or metal and has substantially the same shape as the cast product.

(2) And (5) manufacturing a casting mold. The mold is placed in a flask, the molding sand is refilled, and the sand is tamped. After the mold is removed, a cavity is left in the sand to form a sand mold. This process is called flask molding and is most widely used.

(3) And (6) pouring. The molten metal is poured into a sand mold.

(4) And (4) shakeout and cleaning. After the molten metal is condensed, the molding sand is separated from the casting, the sand adhered on the surface of the casting is removed, and the casting is obtained by repairing burrs, removing defects such as gates, risers and the like.

The resin self-hardening sand is a type (core) sand which is formed by mixing raw sand or regenerated sand with synthetic resin and then automatically hardening at room temperature under the action of a corresponding curing agent. After this type of molding sand used once, because the resin medium alkali easily generated the low melting point silicate with the silica sand effect, the silicate attached to the grit surface leads to the molding sand regeneration retrieval and utilization proportion to reduce, increased the input of new molding sand, reduced molding sand retrieval and utilization proportion, increased manufacturing cost, caused the waste of molding sand.
