Description
Technical field
The utility model relates to foundry machinery field, specially a kind of heavy duty mill housing casting recyclable devices of dry sand.
Background technique
Sand core is for manufacturing the material of type core in Foundry Production, generally by casting model powder, moulding sand binder and additional thing etc.
Modeling Material mixes according to a certain percentage.Type core is largely surrounded by the liquid metal of high temperature in casting mold, and is supported
The size of position portion is typically small, therefore core sand is in addition to the performance that should have general molding sand, also requires to have higher intensity, thoroughly
Gas, deformability and collapsibility.Core sand is divided into clay core sand by binder difference used, waterglass core sand, wick sand, closes rouge core
Sand, resin core sand etc..The type core of simple shape is generally available clay core sand and is made；The relatively thin relatively thin, requirement of complex-shaped, section
The type core that dry strength is high, collapsibility is good, then using wick sand, conjunction rouge core sand or resin core sand.Vegetable oil sand core can get very
Bright and clean casting, but tung oil, linseed oil, modified rice bran oil etc. used, the source of goods is rare, expensive.Therefore China is certainly
Residue (referred to as conjunction rouge) after starting to be widely used soapmaking industrial producing synthetic fatty acid for 1963 makees binder.This core sand
Dry strength, deformability and collapsibility with approximate wick sand.When using wick sand and closing rouge core sand manufacture sand core, before having hardening
Fuse intensity is at a fairly low, easily-deformable, setting rate is slow, the production cycle is long, needs the problems such as drying, and influences the dimensional accuracy of casting
And production efficiency.Use resin as the core sand of binder, comprising: self-hardening resin core sand, Ester cured waterglass core sand, film covered sand core
Sand, hot box core sand, cold-box core sand.Air-setting binder core sand can be used in small lot castings production, and high-volume castings production is answered
Using hot box core sand, cold-box core sand, precoated sand core sand is can be used in particular/special requirement casting.
In high temperature casting process, binder burns totally, and sand core loses binder and can dissipate, and cold core sand is returned
It receives and uses, remain a small amount of binder in cold core sand, cause cold core sand agglomerating, before reusing, it is necessary to sieve to cold core sand
Choosing, current screening mode are using artificial screening, time-consuming and laborious, large labor intensity, and working efficiency is low；In addition scene screening is made
At working environment fugitive dust, it is unfavorable for the health of worker.
