Abstract
The invention relates to a processing method of moulding sand, wherein the moulding sand is prepared from 100 g of refining quartz sand, 1.4 g of xy-640 type alkaline phenolic resin, 0.8 g of an xyG4 type organic ester curing agent and 4 to 6 g of water. The processing method has the advantages of good thermoplasticity and no phenomena of sand washing and sand holes, and the product quality is greatly increased.
Description
Technical field
The present invention relates to cast the processing with Modeling Material, relate in particular to a kind of processing method of molding sand.
Technical background
The effect of molding sand in Foundry Production is very important, and the casting wasted product that causes because of the poor quality of molding sand approximately
Account for 30～50% of the total waste product of foundry goods, present molding sand is generally by the quartz sand of 100g, the flower bulb alkali of 3-4g, the moisture of 3-5g is formulated, the product of its casting is in process of setting, if control the improper just product defectses such as easily generation shrinkage cavity, burr, hot tearing, pore, even affect product quality, greatly increased the enterprise operation cost.
Summary of the invention
The object of the present invention is to provide a kind of processing method of molding sand, it can effectively solve the problem of above-mentioned existence.
The present invention is achieved in that a kind of processing method of molding sand, it is characterized in that: its proportioning is purity quartzite 100g, xy-640 type alkalescent phenol resin 1.4g, xyG4 type organic ester curing agent 0.8g, moisture 4-6g.
Further, the specification of described purity quartzite is the 40-70 order; Described molding sand surface is sprayed with the magnesium masking liquid.
Thermoplasticity of the present invention is good, without sand washing and sand hole phenomenon, has greatly promoted the quality of product.
The specific embodiment
A kind of processing method of molding sand is characterized in that: its proportioning is purity quartzite 100g, xy-640 type alkalescent phenol resin 1.4g, xyG4 type organic ester curing agent 0.8g, moisture 4-6g; The specification of described purity quartzite is the 40-70 order.More than each component put into fixed both arms flow mixer uniform stirring and mix, and make xy-640 type alkalescent phenol resin effectively be coated on the surface of sand grains, then carry out complex modeling with the bottom case, do not contain the harmful elements such as N, S, P in the xyG4 type organic ester curing agent, can eliminate the cast(ing) surface that is caused by above-mentioned element oozes S, oozes P and oozes the gas hole defect that N causes; For preventing that molding sand surface local sand from being washed away by molten metal, at coarse, the irregular metal knob that the corresponding site of cast(ing) surface forms, the present invention is coated with on its surface after the molding sand moulding and is sprayed with the magnesium masking liquid; During concrete the use, the molten steel injection type sand mo(u)ld in the smelting furnace is cooled off, solidifies, carry out at last sand removal and process, so that product surface is without scab, not only bright and clean but also improved the institutional framework stress of product, can carry out recycling to the old sand of cleaning simultaneously, saved cost.
