Abstract
The invention provides a full mold casting molten iron introducing type chill. The full mold casting molten iron introducing type chill comprises a casting full mold, wherein mold sand of an inner cambered surface of the casting full mold is provided with a plurality of polystyrene foam bars; pig iron is pressed on the middle upper parts of the polystyrene foam bars; the foam bars and a casting model body are in seamless connection, and the foam bars can form iron casting bars after pouring; the polystyrene foam bars have the length of 200-400mm, have the width of 30-100mm, have the thickness of 10-30mm, and are distributed in the mold sand with an oblique array interval of 30-150mm, and the installation oblique angle is 5-45 degrees; the included angle of the inner cambered surface of the casting full mold is 15-120 degrees. By utilizing the full mold casting molten iron introducing type chill, the manufacturing cost of the chill is reduced; the casting defect that a thermal joint of a casting is probably easy to shrink is eliminated; the quality of a casting is ensured. The full mold casting molten iron introducing type chill has the characteristics of low manufacturing cost, simple structure, convenience and reliability in clamping, and good effects.
Description
Technical field
The present invention relates to a kind of cavityless casting chill and lay mode, be specifically related to a kind of cavityless casting molten iron introduction-type chill.
Background technology
Conventional cast or general cavityless casting, for eliminating foundry goods thermal center, or reduce and increased store heat because casting structure causes, obtain and perfect foundry goods without Shrinkage cavity, need to lay chill, chill is laid all to adopt and chill is inserted foundry goods body interior and internal densener or be placed to foundry goods body exterior and external chill.But automobile die or other foundry goods need the complex-curved profile of machining, neither allow to place internal densener, common external chill is laid at the curve form position important at foundry goods, often do not reach chill effect again, often there is shrinkage defect in cast-internal, and the Reusability of external chill also may cause the defects such as bleb, casting quality requirement can not be met.
Summary of the invention
The present invention is in order to solve the problem of complex-curved profile cast-internal shrinkage defect and chill effect, and spy provides a kind of cavityless casting molten iron introduction-type chill.
For this reason, technical scheme of the present invention is as follows: cavityless casting molten iron introduction-type chill, comprise casting full-mold, it is characterized in that: in the molding sand of casting full-mold negative camber, be provided with many polystyrene foam bars, the middle and upper part of polystyrene foam bar is pressed with pig, polystyrene foam bar and the seamless connection of casting full-mold.
The improvement of such scheme is: polystyrene foam bar is long is 200-400mm, wide 30-100mm, and thick 10-30 is that 30-150mm is distributed in molding sand by skewed array pitch, its mounting inclination angle degree 5-45 °.
The improvement of such scheme is: the angle 15-120 ° of casting full-mold negative camber angle.
Beneficial effect:
Polystyrene foam bar and the seamless connection of casting full-mold, after cast, polystyrene foam bar can become cast iron bar.
Use cavityless casting molten iron introduction-type chill of the present invention, reduce chill cost of manufacture, eliminate in foundry goods thermal center place or the casting flaw that shrinkage porosite position easily occurs, ensure that casting quality.It is low that the present invention has cost of manufacture, and structure is simple, the feature that clamping is convenient, reliable, effective.
Accompanying drawing explanation
Fig. 1 is plan structure schematic diagram of the present invention.
Fig. 2 is the sectional view of Fig. 1.
In figure, 1 is casting full-mold, and 2 is molding sand, and 3 is polystyrene foam bars, and 4 is pigs.
Detailed description of the invention
The present invention as shown in Figure 1, 2.
Cavityless casting molten iron introduction-type chill, comprise casting full-mold 1, many polystyrene foam bars 3 are provided with in the molding sand 2 of casting full-mold 1 negative camber, the middle and upper part of polystyrene foam bar 3 is pressed with pig 4, polystyrene foam bar 3 and the seamless connection of casting full-mold 1, after cast, polystyrene foam bar 3 can become cast iron bar.
Polystyrene foam bar 3 is long is 200-400mm, wide 30-100mm, and thick 10-30 is that 30-150mm is distributed in molding sand 2 by skewed array pitch, its mounting inclination angle degree 5-45 °.
The angle 15-120 ° of casting full-mold 1 negative camber angle.
The present invention is fine at automobile die complex-curved profile experiment effect, the automobile die cast profile of cavityless casting is without shrinkage cavity shrinkage porosity or other casting flaw, casting quality improves highly significant, when profile thickness 40-60mm, introduction-type chill optimum length 250-300mm, width 60-70mm, thickness 15-20mm, mounting inclination angle degree 15-30 DEG C.In casting pouring process, by foundry goods profile lay introduction-type chill position introduce molten iron, due to this introduction-type chill comparatively foundry goods need Quench position cooling rate to significantly improve, reach chill effect.
