Abstract
The utility model discloses a double-helical internal chill device for rapidly cooling castings, which is arranged in a casting cavity. The double-helical internal chill device comprises a helical line mechanism and core rods, wherein the core rods are arranged in the helical line mechanism; the helical line mechanism is tightly wound with rigid wires; and the number of the core rods in the helical line mechanism is two. According to the utility model, because an internal chill is set into a helical shape, the core rods are arranged in the helical line mechanism, and then the helical line mechanism is placed in the casting cavity so as to carry out cooling on castings. Because the internal chill is set into a helical shape, the cooling speed is promoted, and the cooling effect is good, therefore, a produced casting is high in quality; and the double-helical internal chill device is an extremely good internal chill, and can reduce the production cost of castings, confer benefits to the quality control of large and thick castings, and reduce the casting stress.
Description
Technical field
The utility model belongs to cast steel apparatus technical field, is specifically related to a kind of double helix internal densener device of quick cooling foundry goods.
Background technology
In the cast steel flow process,, often in die cavity or on the surface near foundry goods, lay metal derby in order to increase the local cooling velocity of foundry goods; Such metal derby is called chill, is placed on the interior metal derby of die cavity internal densener, and internal densener becomes the part of foundry goods; Should be close with the material of foundry goods, internal densener is used in the thick greatly and not very heavy foundry goods more, but; The most cooling effect of present internal densener is not very desirable, and casting quality has been caused certain influence.
The utility model content
The purpose of the utility model is to avoid above-mentioned weak point of the prior art, and provide a kind of good cooling results, effectively guarantee casting quality, effectively improve the double helix internal densener device of cooling effectiveness, quick cooling foundry goods easy to use.
The technical scheme that purpose adopted that realizes the utility model is: a kind of double helix internal densener device of quick cooling foundry goods; Be arranged in the foundry goods die cavity; Said double helix internal densener device comprises helix mechanism and core bar, and said core bar is arranged in the helix mechanism.
Said helix mechanism closely arranges winding by rigid filaments and puts.
The said in-house core bar of helix that is arranged on is parallel two.
Because it is spiral-shaped that the utility model internal densener is set to, and in helix mechanism, core bar is set, and is placed on then in the foundry goods die cavity, and foundry goods is cooled off.Since the spiral-shaped cooling velocity that promoted, cooling effect, the casting quality of therefore producing is high, is a kind of good internal densener, can reduce the castings production cost, and quality control is highly profitable to thick and large casting, reduces casting stress.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the sketch map of the utility model when in the foundry goods die cavity, using.
The specific embodiment
Like Fig. 1, shown in Figure 2: a kind of double helix internal densener device of quick cooling foundry goods, be arranged in the foundry goods die cavity 3, said double helix internal densener device comprises helix mechanism 1 and core bar 2, said core bar 2 is arranged in the helix mechanism 1.Said helix mechanism 1 closely arranges winding by rigid filaments and puts, and the said core bar 2 that is arranged in the helix mechanism 1 is parallel two.Said helix mechanism 1 is processed by steel wire, and said core bar 2 is processed by mild steel.
Utilize the utility model, internal densener is set to spiral-shaped, and core bar 2 is set in helix mechanism 1, is placed on then in the foundry goods die cavity 3, and foundry goods is cooled off.Because the spiral-shaped cooling velocity that promoted, cooling effect is a kind of good internal densener.
Claims (3)
1. a double helix internal densener device that cools off foundry goods fast is arranged in the foundry goods die cavity, and it is characterized in that: said double helix internal densener device comprises helix mechanism and core bar, and said core bar is arranged in the helix mechanism.
