Description

Casting flask with shell casting device {THF FLASK WITH FIXING DEVICE FOR SHELL-MOLD}

The present invention relates to a casting flask having a shell mold loading device, and more particularly, to a casting flask having a shell mold loading device so that a plurality of shell molds can be fixedly and stably loaded in the casting flask. .

In general, shell molds (shell molds, hereinafter referred to as shell molds) are cast using a resin coated sand obtained by mixing a binder such as phenol resin with refractory particles such as foundry sand to form a shell mold for product molding. It is a casting method in which molten metal is injected into a shell mold in a flask by molding into a FLASK (hereinafter referred to as a flask) and filling with a steel ball.

Looking back at this; The casting flask where the compacting work is completed by putting the shell mold into the empty casting flask and filling the steel ball is transferred along the transfer line, and the pouring flask is performed while the pouring flask and the product molding are completed. The casting flask is turned upside down to dump the shell mold, the molded product and the steel ball.

Then, the casting flask emptied by the dumping operation is moved to the transfer line again, the shell mold is added as described above to fill the steel ball, and after the compacting operation, forming and dumping the product after the compacting operation.

The casting device for realizing the above-described casting method is performed by a continuous casting line in which various work steps necessary for casting are sequentially performed while circulating the casting flask in which the shell mold is embedded in order to increase the productivity of the product.

As described above, the compacting work in which the shell mold is put into the empty casting flask and the steel ball is filled in the casting flask to fix the shell mold by the steel ball takes much manpower and time for the filling and compacting of the steel ball. This is a factor that reduces productivity and productivity.

In addition, since the steel ball that is added to fix the shell mold in the casting flask is filled between the shell molds to fix the shell mold, there is a disadvantage that the fixing force is not firm due to the flow of the steel balls.

In particular, casting flasks are loaded with a plurality of shell molds, and the casting work is performed. However, the steel balls filled between the shell molds do not allow a larger quantity of shell molds to be loaded, thereby lowering productivity.

That is, since the steel balls are filled in the space between the shell molds for fixing the shell molds, it is impossible to load the shell molds as much as the space occupied by the steel balls, so that the larger quantity of shell molds cannot be loaded in the casting flask. There is a problem of deterioration in efficiency and productivity.

On the other hand, Reference Mold 1 discloses a mold apparatus having a supporter (clamp) for supporting a plurality of laminated molds in a horizontal direction.

The molding apparatus disclosed in Reference 1 is provided with an operation cylinder on one side of a fixed frame to support a plurality of laminated molds in a horizontal direction, and has the following problems in applying the clamping structure of the molding apparatus to a casting flask.

When a hydraulic cylinder supporting a plurality of laminated molds disclosed in Reference 1 in the horizontal direction is applied to a casting flask, there is a high risk of explosion due to heating by hot melt in the pouring process.

In particular, the hydraulic cylinder is connected to the hydraulic power line, so the hydraulic flask cannot interfere with the mobility of the casting flask that is independently moved by the continuous casting line. Therefore, the hydraulic cylinder cannot be installed in the casting flask.

In addition, the working cylinder not only prevents the rotating operation of the inverted casting flask to perform the dumping operation, but also does not empty the casting flask after the casting operation because the shell casting and the molded product cannot be dumped together from the casting flask during the dumping operation of the casting flask. There is a problem, such as not being able to properly perform the continuous casting operation by the casting flask. As described above, the clamping device disclosed in the mold apparatus of Reference 1 cannot be applied to the shell mold fixing apparatus of the casting flask put into the continuous casting line pursued by the present invention.

The shell mold casting method described above in connection with the present invention is disclosed in References 2 and 3.

In addition, the present invention is configured to fix a plurality of shell molds in a casting flask by using a screw jack key used in automobiles and the like, and the screw jack keys are disclosed in various configurations in References 4 to 6 and the like.
