Abstract
A no-bake resin sand chilling block is characterized by adding a resin sand overlay film on a moulding cast iron. The foundry industry employs a graphite chilling block in the prior art; the graphite chilling block is high in cost, too soft in the cooling effect, and a special shape cannot be easily formed; the no-bake resin sand chilling block can solve said problems, and can be widely applied to the foundry industry for cooling casts.
Description
Technical field
The present invention and casting field, the device cooled down to foundry goods by specifically a kind of utilization resin sand.
Background technology
Foundry goods is even because of foundry goods became uneven after being cast, and rate of cooling is different, often shrinkage porosite, shrinkage cavity and draw phenomenon occurs where casting section thickness is big, causes foundry goods to scrap.According to casting Application of Proportional Solidification principle, need most of laying chill thick in foundry goods so as to quick to cool down, reach with thin place while the effect for solidifying, it is to avoid drawbacks described above occur.At present, foundry industry is all cooled down using graphite chilling block, but the cost of graphite chilling block is very high, it is not easy to make special shape, and cooling effect is excessively soft；And it is easily damaged in process of production, need to change in time, increased the cost of production.
The content of the invention
The present invention adopts graphite chilling block high cost to solve foundry industry, and cooling effect is excessively soft, and does not allow to be apt to do the problem of special shape, designs a kind of chill structure of resin sand.
The technical scheme is that, a kind of self-hardening resin sand chill, which is characterized in that, the cushioning resin sand coating layer above the molding cast iron.
It is during operation, first different according to the shape of foundry goods, pour and outpour the molding cast iron for matching, then in upper surface one layer of resin sand coating layer of laying of molding cast iron, then dry.After foundry goods is put, you can coincide as mould and cooled down.Resin sand coating layer can avoid foundry goods from sticking together with molding cast iron, also allow for repairing if any breakage.
The solution have the advantages that, using above-mentioned technical proposal, it is possible to achieve a kind of simple to operate, cool down rapid chill structure.
Description of the drawings
Fig. 1 is the structural front view of the present invention, and the accompanying drawing that makes an abstract.
In figure, 1 molding cast iron, 2 resin sand coating layers, 3 foundry goods.
Specific embodiment
Embodiment below in conjunction with the accompanying drawings, the present invention is further described。
As illustrated, above the molding cast iron 1 cushioning resin sand coating layer 2.It is during operation, first different according to the shape of foundry goods 3, pour and outpour the molding cast iron 1 for matching, then in upper surface one layer of resin sand coating layer 2 of laying of molding cast iron 1, then dry.After foundry goods 3 is put, you can coincide as mould and cooled down.Resin sand coating layer 2 can avoid foundry goods 3 from sticking together with molding cast iron 1, also allow for repairing if any breakage.
