Abstract
The utility model discloses a kind of distortion-free opening chill, comprise the chill body of semi-annular shape, feature is: the both sides of chill body are wholely set one piece of overhanging flanged plate respectively, every block flanged plate offers respectively a locked groove worn for bolt, the outer surface of chill body has been wholely set multiple flange muscle; Advantage is: the multiple flange muscle be wholely set at the outer surface of chill body can play lacing wire effect, prevent opening chill to be out of shape, and ensures the form and dimensional precision of opening chill, guarantees dimensional accuracy and the quality of cast product; Multiple flange muscle also can increase the area of dissipation of opening chill, thus increases the chill effect of opening chill, avoids foundry goods produces the casting flaws such as cold shut, and can reduce the thickness of chill body, reduces materials, reduces costs.
Description
Technical field
The utility model relates to the dieparts in machine casting field, specifically a kind of distortion-free opening chill.
Background technology
In the foundry production of foundry goods, because some product quality requires higher, require that cast-internal can not have casting flaw, so when technological design, need at mould arranged outside chill.The filling moulding outside chill when moulding is produced, taken out by mould after moulding, chill and sand mo(u)ld are linked to be entirety.After casting pouring in cooling procedure, utilize the feature that chill heat conduction is fast, amount of stored heat is large, chilling action is played to foundry goods, prevent the generation of casting inner defect.For toroidal foundry goods, opening chill is comparatively common chill, usual complete use, and its shape is generally the semi-annular shape shown in Fig. 1, and Fig. 1 is front view.Existing opening chill Problems existing is: use several times, due to overheated and excessively cold impact, its opening size and shape change, cause chill dimensional accuracy inadequate, finally easily cause casting dimension deviation even to be scrapped, therefore existing opening chill is short for service life, and deployment cost is high.Way common is at present the distortion being reduced chill by the thickness of increase chill, but chill thickness increases, and can increase chill weight on the one hand, be not easy to move, operate and allocate and transport, and chill cost can be increased, and on the other hand may be excessive to foundry goods Quench, cause the casting flaws such as cold shut.
Summary of the invention
Technical problem to be solved in the utility model is: for the deficiencies in the prior art, provides a kind of distortion-free opening chill.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of distortion-free opening chill, comprise the chill body of semi-annular shape, the both sides of described chill body are wholely set one piece of overhanging flanged plate respectively, flanged plate described in every block offers respectively a locked groove worn for bolt, the outer surface of described chill body has been wholely set multiple flange muscle.During use, two blocks of the utility model opening chills are set in outside mould, bolt is penetrated respectively in two locked grooves, by bolt, two blocks of opening chills are connected, filling moulding outside two blocks of opening chills again, taken out by mould after moulding, chill and sand mo(u)ld are linked to be entirety, then carry out subsequent casting operation.The multiple flange muscle be wholely set at the outer surface of chill body play lacing wire effect, opening chill is prevented to be out of shape, ensure the form and dimensional precision of opening chill, multiple flange muscle also can increase the area of dissipation of opening chill, thus increase the chill effect of opening chill, and the thickness of chill body can be reduced, reduce materials, reduce costs.
Preferably, described multiple flange muscle are arranged along the circumference of the outer surface of described chill body, and described multiple flange muscle are along the axially evenly arrangement of described chill body.Multiple flange muscle is arranged on the circumference of the outer surface of the chill body of semi-annular shape, facilitates the processing of opening chill; Multiple flange muscle, along the axially evenly arrangement of chill body, is conducive to the even Quench of opening chill to each position of foundry goods, make Technique of Casting Microstructure evenly, surface quality is better.In addition, when opening chill is vertically placed, during filling moulding, multiple flange muscle also can play certain hanging sand effect, increases the contact area of opening chill and sand mold, prevents chill from coming off.
Preferably, the outer openings of the locked groove described in two.After the outer openings of two locked grooves, bolt can be loaded in locked groove through opening, operate more convenient.
Preferably, the locked groove described in two is symmetricly set on the both sides of described chill body.Two locked grooves are symmetricly set on the both sides of chill body, can make being interconnected and locating more reliably of two blocks of opening chills, prevent the dimensional discrepancy causing foundry goods because the dislocation of opening chill.
Compared with prior art, the utility model has the advantage of: opening chill disclosed in the utility model comprises the chill body of semi-annular shape, the both sides of this chill body are wholely set one piece of overhanging flanged plate respectively, every block flanged plate offers respectively a locked groove worn for bolt, the outer surface of chill body has been wholely set multiple flange muscle.The multiple flange muscle be wholely set at the outer surface of chill body can play lacing wire effect, prevent opening chill to be out of shape, and ensure the form and dimensional precision of opening chill, guarantee dimensional accuracy and the quality of cast product; Multiple flange muscle also can increase the area of dissipation of opening chill, thus increases the chill effect of opening chill, avoids foundry goods produces the casting flaws such as cold shut, and can reduce the thickness of chill body, reduces materials, reduces costs.

Fig. 2 is the front view of embodiment opening chill;
Fig. 3 is the top view of embodiment opening chill;
Fig. 4 is the left view corresponding to Fig. 3.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As in Figure 2-4, a kind of distortion-free opening chill, comprise the chill body 1 of semi-annular shape, the both sides of chill body 1 are wholely set one piece of overhanging flanged plate 2 respectively, every block flanged plate 2 offers respectively the locked groove 21 of the outer openings that wears for bolt (not shown), two locked grooves 21 are symmetricly set on the both sides of chill body 1, the outer surface of chill body 1 has been wholely set multiple flange muscle 11, multiple flange muscle 11 is arranged along the circumference of the outer surface of chill body 1, and multiple flange muscle 11 is along the axially evenly arrangement of chill body 1.
Each cylindrical mold (not shown) need support the use two blocks of the utility model opening chills.During use, two blocks of opening chills are set in outside mould, in two locked grooves 21, penetrate bolt respectively, by bolt, two blocks of opening chills are connected, then outside two blocks of opening chills filling moulding, after moulding, mould is taken out, chill and sand mo(u)ld are linked to be entirety, can carry out subsequent casting operation.
