Abstract
The resin sand of a kind of molding sand instrument casting, it includes the raw material of following parts by weight: 100 parts of matrix sand material, furane resins 1 ~ 3 part, 0.2 ~ 1 part of firming agent, property-modifying additive 10 ~ 20 parts；Described matrix sand material is quartz sand and electric smelting zircon sand, and its mass parts ratio is 1 ~ 3:1；Described property-modifying additive is one or more in Gypsum Fibrosum powder, Kaolin, meerschaum, hollow glass micropearl, lignin fibre.The resin sand sand mold intensity of a kind of molding sand instrument casting that the present invention prepares is high, dimensional discrepancy is little, collapsibility good, energy resource consumption is few, can be used for the production casting of various molding sand instrument foundry goods, and the surface quality of foundry goods and dimensional accuracy are high.
Description
Technical field
The present invention relates to a kind of moulding sand for casting technical field, be specifically related to the resin sand of a kind of molding sand instrument casting.
Background technology
Molding sand effect in Foundry Production is particularly important, and the casting wasted product caused because of the poor quality of molding sand accounts for casting
The 30～50% of the total rejection number of part.Foundry Production generally requirement to molding sand is: have higher intensity and heat stability, to hold
Acted on by various external force and high temperature；Good mobility, i.e. molding sand are mutually moved between sand grains under external force or action of gravity own
Dynamic ability；Certain plasticity, i.e. molding sand deform under external force, the shape that can keep being given after external force is removed
Ability；Preferably breathability, i.e. molding sand hole are through the ability of gas；High knockability, also known as collapsibility, i.e. at casting solidification
Whether rear molding sand is easily destroyed, if the performance easily removed from foundry goods.
Casting sand used is required higher by molding sand instrument and equipment, and existing molding sand experimental apparatus is at foundry production
In often there is various different casting flaw, such as crackle, pore, sand holes, shrinkage cavity etc., have impact on making of molding sand experimental apparatus
By performance, and the generation of these defects and the caking property between foundry goods and casting sand, detachment are relevant, existing casting sand
Serviceability is poor, easily produces bonding with foundry goods, causes foundry goods to be not easily stripped, and cast breathability, plasticity and flowing
Property is bad, thus causes cast(ing) surface coarse so that Mechanical processing of casting percent defective is higher.
