Description

[Detailed Description of the Invention] The present invention relates to a method for molding ceramics, by using an inner mold made of expanded polystyrene that can be eluted with a solvent.
The purpose is to facilitate molding and also to enable stamping and engraving on the surface of a single work.

The method of using a potter's wheel when molding pottery items with internal cavities, such as conventional flower vases, is not suitable for molded items other than those whose cross section is relatively close to 1 yen, and therefore,
In order to make shapes other than these, the only options were to glue clay plates together or to layer clay in the form of strings.

Also, when stamping etc. is strongly pressed on the surface of a molded product to create a concave shape, or when strong force is applied to add flesh.

To prevent distortion of the clay layer, touch it with your hands from the back side.

It was necessary to apply. These are the conventional methods.

It required extremely advanced technology, and was difficult to mold perfectly because it was prone to deformation due to the clay's own weight.

As mentioned above, this invention is an attempt to eliminate the drawbacks seen in the conventional method. Specifically, the method is to first produce a ceramic product with the same external shape as the internal cavity of the ceramic product to be produced. The inner mold is made by carving a piece of polystyrene, and clay is pasted to a uniform thickness on the surface of the inner mold.
After engraving by pressing stamps etc. on the surface of the clay layer,
After the inner mold is eluted, it is naturally dried for several hours to make it hard enough to prevent deformation due to the clay's own weight.Then, a solvent such as lacquer thinner is injected into the inner mold and the inner mold is made of polystyrene. All you have to do is elute it. In the case of highly luminescent foamed lastyrol, there is little residue after melting, and in the case of small molded products, it almost completely disappears. In addition, if there is melting residue, such as in the case of large molded products, it is sufficient to make an elution hole in the bottom of the molded product and fill it with the same clay after the residue elutes.
or.

Also on the top for molded parts without openings for solvent injection.

Simply drill an injection hole, inject the solvent, and then fill it with clay. Also, if you want to engrave the surface of a molded product, just like when making an engraved pattern, if you do it before the inner mold elutes, the inner mold will serve as the engraving core and you can apply strong force during the engraving. Even if the molded parts meet, the molded product will not be distorted, so you can rest assured.

The inner mold of the 9-polystyrene polystyrene can be easily prepared by cutting, gluing, and cutting the polystyrene using a saw or the like. As described above, according to the present invention, even a ceramic product having a complicated shape of a cavity or a curved surface can be easily molded without requiring any particular specialized skills and even by non-experts. It is possible.
