Field of the Invention The present invention relates to a casting mold for vanishing model casting, and more particularly to a casting mold for vanishing model casting that does not cause casting defects such as so-called scooping. 2. Description of the Related Art In a vanishing model casting method, a casting mold is applied to the surface of a casting to cast it in order to finish the surface of a cast product well and to prevent occurrence of casting defects. I have. The mold was applied to the surface of the disappearing model to a predetermined thickness by using a brush or by immersing the disappearing model in a solution of the mold. The purpose of using a coating mold is to improve the seizure resistance. However, if the component ratio of the coating mold does not match the casting conditions, the post-casting residue will increase, and scooping due to thermal expansion will occur. appear. For this reason, the components contained in the coating mold have been appropriately combined according to the type and size of the cast product, the required accuracy and the like, and according to the main purpose. [0004] However, when a molten metal is poured into a mold, the surface of the coating layer rises in temperature due to the high-temperature molten metal. , The temperature difference occurs on the front and back surfaces of the mold.
Then, the coating mold may be peeled off from the surface of the sand mold, and scooping that may result in poor casting may occur. [0005] Scooping will be described in detail with reference to the drawings. FIG. 7 is a partial cross section of the vanishing model 10 before pouring. The vanishing model 10 is buried in the casting sand 14 with the coating mold 2 applied to the surface. And when pouring, Fig. 8
As shown in (1), the temperature of the surface a of the coating mold 2 in contact with the molten metal 3 becomes high, and a crack occurs on the surface a side of the coating mold 2 due to a temperature difference generated between the surface a and the back surface b of the coating mold 2 having a still low temperature. Further, when the temperature of the coating mold 2 is increased by the molten metal, the surface a is softened or starts to melt.
However, since the temperature of the back surface b of the coating mold 2, that is, the surface in contact with the casting sand 14 has not risen so much, a difference in thermal expansion occurs between the front and back surfaces, thereby causing cracks. When the expansion further proceeds, the coating mold 2 separates from the surface of the molding sand 14 and rises as shown in FIG. Then, the rising portion penetrates into the molten metal 3, and casting defects occur, such as the coating mold 2 penetrating into the surface of the casting product and the molten metal wrapping around the surface of the casting sand 14. [0007] If the density of the mold is large, the foam polystyrene model is deformed or damaged by the weight of the mold when the mold is applied. It becomes difficult and hinders productivity. Also,
After applying the mold, the model may be deformed by the weight of the mold, or a crack may be generated on the surface of the mold to cause a defect on the surface of the cast product. [0008] It is an object of the present invention to solve the above-mentioned problems and to provide a casting mold that does not cause casting defects such as scooping. In the present invention, in order to solve the above problems, a casting mold is constituted as follows. That is, fused silica and clay are used as the main aggregate, the carbon content in the main aggregate is set so that the linear thermal expansion coefficient up to 1500 ° C. is 0.02% or less, and the coating mold after drying. With a density of 1.5 g / cm 3 or less, to constitute a vanishing model casting coating mold. As a result, the requirements required as a mold in casting can be satisfied, a good casting operation can be performed, and the difference in thermal expansion due to the temperature difference during casting can be reduced, and scooping does not occur. In addition, the mold does not break due to its own weight, and casting defects do not occur. Therefore, the labor and cost of the casting operation can be significantly reduced, and a good cast product can be obtained. In addition, since the density of the main aggregate is much smaller than that of the alumina or zircon coating by using fused silica, there is no deformation or breakage of the model,
Workability can be improved even for large castings. The casting mold of the present invention will be described below. FIG. 1 shows an example of casting. FIG. 1 shows casting by the vanishing model casting method. First, a vanishing model 10 is installed inside a casting flask 12, and casting sand 14 is charged and buried. The vanishing model 10 is made of styrene foam having a hole 13, and a coating mold 2 is applied to the entire surface in advance to a predetermined thickness. In the mold 2, the aggregate is fused silica and clay, and the aggregate contains scaly graphite as a carbon component so that the linear thermal expansion coefficient of the mold 2 is 0.02% or less. I have.
Further, other necessary components are appropriately added to the coating mold 2. When the coating mold 2 is applied to the entire surface of the disappearing model 10 to a predetermined thickness, and after being dried, it is placed in the casting frame 12 and the casting sand 14 is charged and buried, the molten metal is poured from the gate 16, Manufacture casting products. After the casting, the casting frame 12 is unframed to take out the cast product, and then the entire surface of the cast product is shot blasted to remove the applied mold 2, the molding sand 14, and the like.
Take out the product. No scooping or the like was observed on the surface of the manufactured cast product, and a good cast product was obtained. Therefore, according to the mold of the present invention, it is possible to obtain a cast product without scooping of the coating mold due to thermal expansion or the like and free of casting defects. If the cast product is large, for example, if the weight of the product is 10,000 kg or more, the density of the coating mold 2 after drying is 1.5 g / cm 3 or less. With such a setting, a good cast product can be obtained without deformation of the disappearing model due to the weight of the applied coating mold 2, and productivity can be improved. The carbon component contained in the coating mold 2 may be earth graphite, anthracite, electrode scrap, or quiche graphite, instead of scaly graphite as in the above example. When the respective components are different, the densities are different, so that the volume ratio of the scale graphite and other carbon components changes accordingly. EXPERIMENTAL EXAMPLE 1 Next, an experimental example of a coating mold will be described. In the experiment, a coating mold 2 was formed by changing the blending components, and casting was performed using the coating mold 2. Coating mold 2 uses fused silica as an aggregate, and the amount of scaly graphite as a carbon component is 20% from 0% to 60%.
Each was varied and comprised of 8% clay. Further, a small amount of a surfactant, a styrene-based binder, and water are added for dispersion and thickening, and the density is 1.5 g / cm 3.
A coating pattern of Baume 60 was manufactured as follows. In the casting operation, as shown in FIG. 2, four vanishing models 17 of the same shape were placed in the same casting flask, and casting sand 14 was charged and buried. The disappearance model 17 is a block made of styrofoam.
The coating mold 2 was changed to a predetermined thickness by changing from 20% to 60% every 20%. After casting, the frame was unframed to take out a test piece, followed by shot blasting to remove the coating mold 2 and the molding sand 14 adhering to the surface. Then, the difference in the casting surface due to the difference in the amount of scaly graphite added was compared. As a result, when the amount of scaly graphite was 0% and 20%, the casting had no surface defects and had a very clean casting surface as shown in FIG. On the other hand, in the castings cast using the molds in which the amount of scaly graphite added was 40% and 60%, as shown in FIG. 6, surface defects of scooping occurred near the center portion Seki. . This is due to the temperature difference during casting.
It is considered that the difference in thermal expansion became large and scooping occurred. From this, it can be seen that if the scale graphite content is 20% or less, there are few scooping defects and the casting surface is good. Also, after the entire surface of the styrofoam block is coated with the coating mold 2 and dried, the model is deformed by the weight of the coating mold, cracks are generated on the surface of the coating mold,
There is no difficulty in transporting the model, and productivity can be improved. Experimental Example 2 Further, the thermal expansions of the coating molds 2 having different amounts of graphite were measured. Coating mold 2 in which the amount of scaly graphite added was changed from 0% to 60% in increments of 20%, was 10 mm in diameter and 50 mm in length.
Into a bar-shaped sand mold to produce a thermal expansion test piece. The test piece was dried slowly without cracking, and the coefficient of thermal expansion was measured using a horizontal thermal dilatometer (DL-7000Y) manufactured by Vacuum Riko Co., Ltd. The results are shown in FIG. 3 and FIG. FIG. 4 shows that the coefficient of thermal expansion decreases as the content of carbon in the mold decreases. The coefficient of thermal expansion of the mold containing 60% graphite is 0.094%, while the coefficient of thermal expansion of the mold containing no graphite is 0.012%, which is about 1/8.
It can be seen that the decrease in the coefficient of thermal expansion reduces the amount of warpage of the coating mold and makes it less likely to cause defects due to scooping. According to the casting mold of the present invention, there is little thermal expansion, no scooping even if a temperature difference occurs due to pouring, and no casting defects. . Further, the density of the coating after drying is 1.5 g / c.
By set to m 3 or less, even when applied to evaporative pattern, can be deformed to model the weight of the coating type without obtaining good cast product.
