Abstract

PROBLEM TO BE SOLVED: To deter the generation of a distortion in a tile after baking, thereby improving the dimensional precision and the good appearance by constituting either of a second surface molding half of a molding die or a first surface molding half thereof an elastic body for forming a pressure face, a rigid body which is formed monolithically with the elastic body and a base part which supports the peripheral edge of the elastic body while sealing liquid into the back face side of the rigid body. SOLUTION: This molding die consists of a form 3 with a horizontal upper face and a molding space S formed penetrating vertically through the form 3 and a second surface molding half 5 of a molding die and a first surface molding half 4 thereof stored, in a movable manner, in the molding space S. The second surface molding half 5 is formed of a base part 51 made of a metal with an upper face recessed like a pyramidal trapezoid, a rubber plate 53 as an elastic body which has the peripheral edge supported on the base part 51 and forms a pressurizing face 5a, a metal plate 54 which becomes a single piece with the rubber plate 53 on the second surface side and oil 52 as a liquid sealed together with the base part 51 on the second surface side. Consequently, even when a powder raw material 1 cannot be uniformedly packed in the entire cavity, a uniform hydrostatic pressure is generated in the oil 52, resulting in the deformation of the rubber plate 53. Thus it is possible to apply a uniform pressurizing force to the powder raw material 1.

However, in forming the tile base, it is important to make the density of the powder raw material 1 in the tile base uniform throughout.

That is, the tile substrate shrinks as a whole by firing, and this shrinkage is affected by the density of the powdery raw material 1 in the tile substrate. That is, when the density of the powder raw material 1 in the tile base is high, the shrinkage is small, while when the density of the powder raw material 1 in the tile base is low, the shrinkage is large. For this reason, if there are a high density part and a low density part of the powder raw material 1 in the tile base, a part having a large shrinkage rate and a part having a small shrinkage rate are generated during firing, and as a result, the tile obtained after firing is distorted. There is.

However, this is difficult under the automation by a machine using a mold as described above. That is, in the above-described mold, when the powder box 2 slides on the cavity, the upper layer portion of the powder raw material 1 in the cavity is dragged forward by the powder box 2 and the powder A lot of body material 1 will be filled. Conversely, when the powder box 2 slides back on the cavity, the upper layer portion of the powder material 1 in the cavity is dragged rearward by the powder box 2, and the powder raw material 1 is largely behind the cavity. Will be filled. When the reciprocating sliding of the powder box 2 is completed and the raw material supply step is completed, as a result, a large amount of the powder raw material 1 is filled in the rear side of the cavity as shown in FIG. When the pressurizing step is performed as it is,
In the obtained tile base, the density of the powder raw material 1 is not uniform over the whole, and the density of the powder raw material 1 on the rear side is higher than that on the front side. This results in distortion of the fired tile.

Of course, since the non-uniformity of the density of the powder raw material 1 is very small, if a small tile is to be produced, the problem of distortion after firing hardly occurs. However, if a large tile of, for example, 300 mm square or more is to be produced, distortion after firing becomes a serious problem due to the unevenness of the density.

On the other hand, in order to make the density of the powder raw material 1 in the tile base uniform throughout the entirety, Japanese Patent Laid-Open No.
As disclosed in Japanese Patent Publication No. 202-202, it is conceivable to adjust the pressing force. As shown in FIG. 10, the molding die used in this method includes a base 73 having a peripheral edge 73a projecting upward, an elastic body 72 constituting a pressing surface 71a flush with the upper surface of the peripheral edge 73a, A back-side molding die 85 comprising the liquid 72 sealed together with the base 73 on the back side of the body 72 is employed.

According to this molding die, even when the powder material 1 cannot be uniformly filled in the entire cavity in the raw material supply step, a uniform hydrostatic pressure is generated in the liquid 72 in the pressurizing step, and the elastic body 72 is deformed. Therefore, a uniform pressing force can be applied to the powder raw material 1 filled in the cavity. For this reason, a portion where the density of the powdery raw material 1 is high and a portion where the density is low are not generated in the tile base material, and a difference in shrinkage ratio does not occur during firing, so that distortion of the tile after firing can be prevented.

For this reason, if this tile base is fired, a tile having a thick portion and a thin portion in the central region will be produced. In particular, even if the unevenness of the filling amount of the powdery raw material 1 is local, the unevenness appears locally on the tile surface as it is, so that the appearance is inferior.

In the mold according to the first aspect of the present invention, the powder box slides back and forth on the cavity, so that even if the powder material cannot be uniformly filled in the entire cavity in the material supply step, the powder is uniformly dispersed in the liquid in the pressurizing step. Since the elastic body is deformed due to the generation of an appropriate hydrostatic pressure, a uniform pressing force can be applied to the powder raw material filled in the cavity. On this occasion,
The periphery of the elastic body is supported by the base, and the rigid body that is integral with the elastic body on the back side of the elastic body is not on the periphery of the elastic body. Therefore, deformation of the elastic body at such a position is allowed. For this reason, a portion where the density of the powder raw material is high and a portion where the density is low are not generated in the tile base material, and a difference in shrinkage rate does not occur during firing, so that distortion of the tile after firing can be prevented.
