Abstract
A technology for casting iron casting features that the original clay sand mould is changed into resin sand mould, which has many metal exhaust pipes installed in sand box and fixed by locating sleeve. Compared with clay sand mold, the method has the advantages of yield improvement by 20%, cost reduction by 30%, simple process, pollution reduction and low labor intensity.
Description
The present invention is a kind of novel technique in the casting industry.
Existing ironcasting casting technique is moulding of clay-bonded sand full pattern and plate moulding.During moulding, mixed clay-bonded sand is poured in the sandbox, by artificial and mechanical ramming, put into drying kiln again and dry then, last mould assembling cast.Adopting its shortcoming of ironcasting of this technology casting is that qualification rate is low, and the sand removal difficulty is big, the labour intensity height, and dust pollution is serious, and production efficiency is low, and mold drying needs 24 hours to the mould assembling cast, has had a strong impact on economic benefit of enterprises.
The purpose of this invention is to provide a kind of efficient height, quality is good, and labour intensity is low, reduces the ironcasting New Casting Technique of polluting.
Solution of the present invention is: change phenolic sand molding into by original clay-bonded sand moulding.The making of its sandbox and moulding according to the capacity of molten iron in sand mold, are determined mold thickness, make sand mold defeated and dispersed fully after cast.
In order to solve the problem that the inherent gas difficulty or ease of resin bonded sand mould are got rid of, the design adopts from resin bonded sand mould, is provided with many metal exhaust tubes (3), and blast pipe (3) is installed in the inside of sandbox, utilizes positioning sleeve (2) fixing, and communicates with the sandbox external venting.The quantity that blast pipe (3) is installed is determined according to the structure of foundry goods.Blast pipe (3) is provided with the exhaust circular hole (6) of rule, through exhaust circular hole (6), resin bonded sand mould is entered blast pipe (3) at a large amount of gases that cast burning back is produced, after steam vent (7) excrete.Not interrupted when gas is discharged, accelerate the velocity of discharge of gas, locate to be provided with the device of air and outside air convection in the isolated sand mold before the cast at exhaust sky (7), thereby form non-mechanical vacuum casting, reach the purpose of fast smooth exhaust.The sand mo(u)ld that utilizes resin bonded sand mould to make, after 25 minutes, the use of can hardening, thus replaced by the conventional method of past with artificial or mechanical ramming.Resin sand can use after simple process continuously.
Advantage of the present invention is, technology is simple, reduces and pollutes, and labour intensity is low, production efficiency height, product quality and yield rate height.Compare with the clay sand mold, enhance productivity 25 times, casting yield improves 20%, reduces cost 30%, has very high economic benefit and social benefit, is a kind of new technical matters of casting industry.

Claims (3)
1, ironcasting New Casting Technique is characterized in that changing resin bonded sand mould into by the clay sand mold.In the resin bonded sand mould, be provided with many metal exhaust tubes, blast pipe is installed in the inside of sandbox, utilizes positioning sleeve to fix.
2,, it is characterized in that blast pipe is provided with the exhaust circular hole of rule according to claim 1 described ironcasting New Casting Technique.By the exhaust circular hole resin bonded sand mould is entered blast pipe at a large amount of gases that cast burning back is produced, after steam vent excretes.
3, according to claim 1 described ironcasting New Casting Technique, it is characterized in that the steam vent place, be provided with the device of air and outside air convection in the isolated sand mold.Thereby form non-mechanical vacuum casting and reach fast the purpose of exhaust smoothly.
