Abstract
The utility model discloses a kind of casting technique composite iron chill, and it includes graphite chilling block and cast iron chill, and the graphite chilling block is used to be arranged on casting in intimate contact, and the cast iron cold is very tight to be pressed on the graphite chilling block and separate with the casting.The casting technique composite iron chill combines graphite chilling block and cast iron chill, and cast iron chill does not contact directly with casting, the problem of can effectively avoiding merely using slag inclusion next to casting belts during cast iron chill, cold shut.And die casting iron chill on graphite chilling block, because cast iron chill density is high, weight weight, it can effectively prevent graphite chilling block positioning, offset problem occur in casting process, while reduce cost.
Description
Technical field
The utility model belongs to casting technology field, and in particular to a kind of casting technique composite iron chill.
Background technology
Increase casting Local cooling speed usually using chill in casting technique, prevent casting from producing shrinkage cavity and porosity, than
As shown in figure 1, to be placed with chill 2 on casting body 1 (wind power hub casting, its bend are hatching) screw cold to increase
But speed.Chill 2 generally selects cast iron chill or graphite chilling block, and thickness is set to 70mm or so.Wherein cast iron chill has surface
The problem of of poor quality and easy-to-rust itself, in process of production, easily come slag inclusion, cold shut problem to casting belts, it is difficult to solve.Graphite
Chill has the advantages that refractoriness is high, and thermal conductivity factor is big, and can prevent casting generation slag inclusion and cold shut problem, but graphite chilling block
It is low with density, it is in light weight the shortcomings that, easily occur sideslip, the phenomenon of displacement in process of production, and cost is higher.
Utility model content
Therefore, for cast iron chill in the prior art or graphite chilling block easily occur in casting technique slag inclusion, cold shut and
The problem of sideslip, the purpose of this utility model are to provide a kind of casting technique composite iron chill that can avoid above mentioned problem.
Casting technique of the present utility model includes graphite chilling block and cast iron chill with composite iron chill, and the graphite chilling block is used for
It is arranged in intimate contact on casting, the cast iron cold is very tight to be pressed on the graphite chilling block and separate with the casting.
Preferably, the graphite chilling block is flat, the graphite chilling block shape matches with the casting upper surface.
Preferably, the cast iron chill is truncated cone-shaped and upper surface is more than lower surface.Area of dissipation can be effectively increased with this,
Improve cooling velocity.
Preferably, the graphite chilling block thickness is the preferred 30mm of 20~40mm, the cast iron chill thickness is 40~70mm
It is preferred that 50mm.
Preferably, the casting is wind power hub casting.
The beneficial effects of the utility model are：Casting technique composite iron chill of the present utility model is by graphite chilling block and casting
Iron chill combines, on the one hand, cast iron chill does not contact directly with casting, to casting when can effectively avoid using cast iron chill merely
The problem of slag inclusion that brings, cold shut.On the other hand, compared with using graphite chilling block merely, die casting iron chill on graphite chilling block, by
In cast iron chill density height, weight weight, it can effectively prevent graphite chilling block positioning, offset problem occur in casting process, and
Cast iron chill cost is low, can also recycle repeatedly, substantially reduces chill cost.
Brief description of the drawings
Fig. 1 is the application schematic diagram of existing chill；
Fig. 2 is the application schematic diagram of casting technique composite iron chill of the present utility model.
Reference
Casting body 1, existing chill 2, casting technique composite iron chill 3, graphite chilling block 31, cast iron chill 32.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.It should be understood that following examples are only used for
Bright the utility model is not for restriction the scope of the utility model.
Embodiment 1
Fig. 2 show a preferred embodiment of the present utility model, and its medium casting body 1 (wind power hub casting) is provided with casting
Make technique composite iron chill 3, including graphite chilling block 31 and iron casting 32.Graphite chilling block 31 is in close contact with casting body 1, is
Flat and shape and the contact portion profile of the upper surface of casting body 1 match.Cast iron chill 32 is pressed on graphite chilling block 31
Above and with casting body 1 separate, be more than lower surface for truncated cone-shaped and upper surface.Preferably, the thickness of graphite chilling block 31 be 20~
The preferred 30mm of 40mm, the thickness of cast iron chill 32 are the preferred 50mm of 40~60mm.
It is of the present utility model to combine graphite chilling block 31 and cast iron chill 32, on the one hand, cast iron chill 32 not with casting sheet
Body 1 directly contacts, the problem of can effectively avoiding merely using slag inclusion next to casting belts during cast iron chill, cold shut.On the other hand,
Compared with using graphite chilling block merely, die casting iron chill 32 on graphite chilling block 31, can because cast iron chill density is high, weight weight
Effectively to prevent graphite chilling block positioning, offset problem occur in casting process, and cast iron chill cost is low, the cast iron of truncated cone-shaped
Chill 32 can also recycle repeatedly, substantially reduce chill cost.
The preferred embodiment created to the utility model above is illustrated, but the utility model is created not
It is limited to embodiment, those skilled in the art are a variety of etc. without prejudice to can also make under the utility model precondition for innovation
Same modification or replacement, these equivalent modifications or replacement are all contained in the application claim limited range.
