Abstract
The utility model relates to a water cooling core bar for quickening cooling of a casting. The water cooling core bar for quickening cooling of the casting comprises a cooling pipe and a spiral wing piece, wherein the spiral wing piece is fixed on the outer wall of the cooling pipe, and the cooling pipe and the spiral wing piece are squeezed and fixed in an integrated roll forging mode. The spiral wing piece is arranged on the outer surface of an existing water-cooling core pipe, and cooling water is arranged in the core pipe in a communication mode, so that the contact area of the core pipe and a sand mould is increased, cooling speed of metal liquid in the casting is quickened, production of a cast defect is avoided, and casting quality of a workpiece is ensured.
Description
Technical field:
The utility model belongs to the sand casting technical field, is specifically related to a kind of foundry goods cooling water cold core bone that accelerates in sand casting.
Background technology:
When carrying out Foundry Production, for the larger foundry goods of wall thickness, in the cooled and solidified process, the area of dissipation of foundry goods interior metal liquid is little, cooling capacity is limited, and this position is final set often, because setting time is longer, without the molten metal feeding, coarse grains and shrinkage porosite class defective appear easily in the tissue again.Valve body class foundry goods particularly, the bottom is thick large, and setting time is longer in cooling procedure, and crystal grain is easily grown up in the tissue, does not have the molten metal feeding if solidify the later stage middle part, centre porosity will occur, shrinkage cavity can occur when serious.In order to guarantee product quality, some enterprises have adopted water core to accelerate cooling aborning, but common water core relies on the heat of water wall and core to conduct to accelerate cooling, contact area is limited, effect is not very good, if strengthen the diameter that contact area just requires to increase water cooling tube, and along with the increase of diameter, can bring inconvenience to moulding and assembling, also increase production cost.
The utility model content:
In sum, in order to overcome the deficiency of prior art problem, the utility model provides a kind of acceleration foundry goods cooling water cold core bone, it is at existing water-cooled core tube outer surface helical wing plate to be set, logical cooling water in the core pipe, thus the contact area of increase core pipe and sand mold is accelerated the cooling velocity of foundry goods interior metal liquid, avoid the generation of casting defect, guarantee workpiece casting quality.
For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that
A kind of acceleration foundry goods cooling water cold core bone, wherein: comprise cooling tube and helical wing plate, helical wing plate is fixed on the outer wall of cooling tube, and cooling tube and helical wing plate one roll forging extruding are fixing.
Further, described helical wing plate and the edge thickness of the thickness cooling tube junction greater than helical wing plate.
The beneficial effects of the utility model are:
1, the utility model is at existing water-cooled core tube outer surface helical wing plate to be set, logical cooling water in the core pipe, thus the contact area of increase core pipe and sand mold is accelerated the cooling velocity of foundry goods interior metal liquid, avoid the generation of casting defect, guarantee workpiece casting quality.
2, the cooling water circulation is arranged in the cooling tube of the present utility model, guarantee that cooling tube temperature in metal liquid solidification process is unlikely too high, preferably rigidity is arranged, avoided the situation of floating core or fuse distortion; The existence of fin has increased the contact area of water-cooled arbor and foundry goods, and fin and cooling tube be an integral body, and heat conduction efficiency is high; This device has solved the defectives such as shrinkage porosite of the thick large part of foundry goods well, particularly for large thick-wall foundry goods better effects if.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of acceleration foundry goods cooling water cold core bone, comprise cooling tube 1 and helical wing plate 2, helical wing plate 2 is fixed on the outer wall of cooling tube 1, cooling tube 1 is fixing with helical wing plate 2 one roll forging extruding, helical wing plate 2 and the edge thickness of thickness cooling tube 1 junction greater than helical wing plate 2.
During use, the utility model is put in the core box, makes core as arbor, after core is carried out, baking oven, lay core, mould assembling, then the end with cooling tube 1 is connected with cooling water recirculation system, pouring into a mould first three minute begins logical cooling water, to guarantee that stable cool cycles is arranged when the cast.
Be noted that, above-described embodiment is to the explanation of technical solutions of the utility model and unrestricted, other modification that is equal to replacement or makes according to prior art of affiliated technical field those of ordinary skill, as long as do not exceed thinking and the scope of technical solutions of the utility model, all should be included within the desired interest field of the utility model.
