Abstract
The invention relates to a compaction-free forming iron chill which comprises a tile-shaped formed bottom and a convex upright part. A plurality of anti-separating grooves are arranged on two lateral surfaces of the convex upright part. The cambered surface shape of the tile-shaped formed bottom is matched with a part contacting with a casting model, and the tile-shaped formed bottom covers 30-60 percent of the area of a casting journal. The compaction-free forming iron chill has simple and reasonable structure; and in the process of placing the iron chill, the tile-shaped formed bottom and the part contacting with the casting mode are assembled together in a zero clearance fit relationship; the supporting action formed by the iron chill and the lateral surface of the model is strong; the iron chill can be automatically fixed without manpower compaction, avoid casting fin and casting burrs, greatly reduce the sand inclusion, remarkably reduce chock defects and improve the liftability of sand mixture. The compaction-free forming iron chill is suitable for producing automatic modeling crankshaft casting.
Description
Technical field
The present invention relates to a kind of casting chill, the compaction-free forming iron chill that specifically a kind of crankshaft casting is used.
Background technology
We know, during crankshaft casting is produced, are to guarantee casting quality, need install chill additional usually at the heat energy-saving position of main shaft and connecting rod, and chill is to the effect that improves rising head and prevent that foundry goods from producing shrinkage cavity, shrinkage porosite, guarantees that casting quality plays a part outbalance.The structure of chill, shape not only determine the chill effect of foundry goods in the automatic modeling crankshaft casting production process, also labor intensity of operating personnel and production efficiency are produced bigger influence.
Usually the automatic modeling crankshaft casting chill all surrounds axle journal, and there are the gap in chill and model boss.And lay in the chill process and need manually carry out pre-consolidation with facing sand, not only increase working strength of workers, also influence operating efficiency; Because there are the gap in chill and model, molding sand is more loose, and foundry goods forms casting flaws such as fleshiness, overlap, burning into sand easily; Chill all surrounds axle journal, easily causes the axle journal pore, casting flaws such as the fire of choking, sticking chill, and presentation quality is relatively poor.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of simple and reasonable for structure, need not carry out pre-consolidation in the chill installation course, labour intensity reduces greatly, operating efficiency obviously improves, foundry goods molded appearance quality is good, the compaction-free forming iron chill that product quality is high.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of compaction-free forming iron chill is characterized in that: it includes watt formation type bottom and protrudes upright portion two parts, protrudes upright portion two sides and is provided with several anticreep grooves.
Contact with the casting pattern shape of part of the arc shape of said watt of formation type of the present invention bottom is coincide the 30-60% of watt formation type bottom covering casting pattern axle journal area.
Chill of the present invention is by watt forming the type bottom and protruding upright portion integrative-structure dimerous, chill watt formation type bottom is consistent with the shape of contacted boss of casting pattern and axle journal, match, protrude upright portion two sides and be provided with the anticreep groove, against existing technologies, the present invention is simple in structure, rationally, chill is in installation course, a chill watt formation type bottom is no gap matching relationship with casting pattern boss and axle journal and is placed to, and the support effect that chill and model side form is strong, can fix automatically, and good fixing effect, remove artificial consolidation from, avoided casting fin, hard edges, burning into sand reduces greatly.The area that chill covers the casting pattern axle journal is 30-60%, and axle journal pore, the fiery defective of choking obviously reduce, and presentation quality improves.The upright portion of the protrusion of chill two sides are provided with the anticreep groove, and the liftability of molding sand is improved.Compaction-free forming iron chill of the present invention is fit to the production of automatic molding line automatic modeling crankshaft casting.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is a user mode schematic diagram of the present invention;
Fig. 2 is the schematic side view of Fig. 1.
1. protrude upright portion among the figure, 2. anticreep groove, 3. watt formation type bottom, 4. casting pattern.
The specific embodiment
From Fig. 1, Fig. 2 as can be seen, a kind of compaction-free forming iron chill, it includes watt formation type bottom 3 and protrudes upright portion 1 two parts, and two parts are formed the integrated chill that the cross section is " ⊥ " type structure.Wherein the effect of watt formation type bottom 3 is the molten iron at Quench thermal center place.Protrude upright portion 1 structure that assumes diamond in shape, its two sides are provided with several anticreep grooves 2.The effect of protruding upright portion 1 is the Quench ability that increases chill.The effect of anticreep groove 2 is to make chill be fixed in the sand mold difficult drop-off.
The arc shape of said watt of formation type of the present invention bottom 3 and casting pattern 4 shape partly that contacts is consistent, matches.Casting pattern 4 contacts with a watt formation type bottom 3 and partly comprises the boss and the part axle journal of casting pattern 4.Watt formation type bottom 3 covers the 30-60% of casting patterns 4 axle journal areas.Protrude upright portion 1 two sides and be provided with anticreep groove 2.Chill is in installation course, and the support effect that utilizes chill and casting pattern boss, axle journal and side to form is fixing automatically, and good fixing effect, removes artificial consolidation from, enhances productivity.Avoided casting fin, hard edges, burning into sand reduce greatly.The area that chill covers the foundry goods axle journal is 30-60%, and axle journal pore, the fiery defective of choking obviously reduce, and presentation quality improves.The upright portion of the protrusion of chill two sides are provided with the anticreep groove, and the liftability of molding sand is improved.Compaction-free forming iron chill of the present invention is fit to the production of automatic molding line automatic modeling crankshaft casting.
Claims (2)
1. compaction-free forming iron chill is characterized in that: it includes watt formation type bottom and protrudes upright portion two parts, protrudes upright portion two sides and is provided with several anticreep grooves.
2. compaction-free forming iron chill according to claim 1 is characterized in that: contact with the casting pattern shape of part of the arc shape of said watt of formation type bottom is coincide the 30-60% of watt formation type bottom covering casting pattern axle journal area.
