公知となっている。2. Description of the Related Art In recent years, it is preferable that the surface of the outer wall of the exterior of a store or a house has a natural atmosphere, a unique taste, a moderate variation, a broken stone shape, a rock surface shape, and a brick tone. It is becoming more and more. Therefore, in order to make it look as if the outer surface was made of brick, concrete was mixed with a coloring agent, formed into a thin plate and dried to obtain a brick-like concrete plate with reduced cost. A technique for attaching a plate to an outer wall is known.

しようとする。However, when a brick-like concrete is used to form a brick-like concrete, the concrete has poor weather resistance, and is particularly vulnerable to freezing. It was chipped and spoiled the appearance, and replacing this cracked or missing part was a very laborious task. Therefore, in the present invention, in order to make the tile look like a rough brick, the surroundings are collapsed so that the tile can be manufactured at low cost.

First, the method of re-pressurizing will be described with reference to FIGS. Reference numeral 1 denotes a frame mold, in which a rectangular molding space 4 in a plan view is formed, and the front side of a lower mold 2 made of metal is inserted into the molding space 4 to form the molding space 4.

As shown in (b), by lowering the upper die 3, the tile raw material 6 is pressed and molded to obtain a tile molded body 7. The pressing force at this time is approximately 200 kgf / cm in the case of this embodiment.
About 2 . Next, as shown in FIG. 1C, both the lower mold 2 and the upper mold 3 are raised while releasing the pressure applied to the tile molded body 7 so that the tile molded body 7 does not collapse or break. . At this time, the tile mold 7 is substantially in contact with the lower mold 2 and the upper mold 3. In some cases, the frame mold is lowered in a state where the upper mold and the lower mold are substantially in contact with each other.

Then, when the upper mold 3 is lowered from the state where the periphery of the tile molded body is opened and pressed again with a weak force, that is, a force very small than the pressing force at the time of molding, the periphery of the tile molded body collapses. The result is an irregularly collapsed aspect. In this embodiment, the re-pressing force is about 5 to 10 kg.

As shown in FIG. 3, an elastic body 5 made of rubber or the like is attached to the surface (molding space side) of the lower mold 2 and the upper mold 3. The elastic body 5 has a thin central portion, and has irregularities on its surface which can be transferred like a brick surface or a broken stone surface. Then, the periphery of the elastic body 5 is thickened or raised so as to surround the periphery of the tile molded body 7, and the convex edge portion 5a is formed.
Is formed. The surface is also formed with irregularities that can be transferred like a brick surface or a broken stone surface like the central portion. The hardness of the elastic body 5 is about 65 to 85 degrees, and the conventionally used rubber for soles is 90 to 85 degrees.
100 degrees. If the hardness of the elastic body 5 is less than this, it is too soft to form a tile,
The elastic body 5 is crushed or torn. If it is too hard, compression and expansion described below cannot be obtained, no collapse can be obtained, and the mold cannot be released from the mold.

As shown in (1), first, elastic bodies 5 are attached to the lower mold 2 and the upper mold 3, respectively, and the molding formed by the elastic body 5 of the frame mold 1 and the elastic body 5 of the lower mold 2 in the same manner as described above. The space 4 is filled with the tile raw material 6. Next, as shown in FIG.
The upper mold 3 is lowered to press-form the tile material 6 between the upper mold 3 and the lower mold 2. At this time, the elastic body 5 is also compressed, and pressure is accumulated particularly in the peripheral edge portion 5a which is a thick portion around the elastic body 5. Then, as shown in FIG. 4A, both the lower mold 2 and the upper mold 3 are raised while releasing the pressure applied to the tile molding 7 (co-raising). At this time, the elastic body 5 expands vertically. Due to this expansion, the periphery of the tile molded body 7 having a large expansion coefficient is displaced by the convex edge portion 5a of the elastic body 5, and a part of the side surface of the tile molded body 7 is broken.

る。Next, as shown in FIG. 4B, when the frame die 1 is lowered from the above state, the protruding edge portion 5a of the elastic body 5 located on the side surface of the tile molded body 7 is exposed from the frame die 1. Then, the force accumulated in the elastic body 5 by the pressure molding is released, the elastic body 5 expands, and the protruding edge portion 5b spreads to the side. on the other hand,
The lateral surface of the elastic body 5 causes the side surface of the tile molded body 7 to collapse. Then, when the upper die 3 is raised from this state, as shown in FIG.
5 is separated and returns to the original state, and the collapsed collapsed object 7a falls to the surroundings. Since the amount and size of the collapsed fallen object 7a are not the same and the components of the tile itself are not uniform,
Depending on each tile, the side shape is also irregular,
It becomes moderately variable. Then, the tile molded body whose side has collapsed is sent to the next step.

Alternatively, the elastic body 5 is attached only to the surface of the upper die 3 so that the height of the protruding edge portion 5a formed around the elastic body 5 is substantially the same as the thickness of the tile. Be able to surround it.

The tile raw material was press-molded by the frame mold, the upper mold and the lower mold, and the tile molded body after the press molding was taken out of the frame mold, and the tile molded body was re-pressed so that the periphery thereof collapsed. By simply changing the elevation control program of the upper mold (or lower mold) that performs molding, it is possible to add other parts for manufacturing, mix other substances with raw materials, add processing in the post-process, etc. Without this, brick-like tiles with unevenly collapsed surroundings can be obtained.

An elastic body is attached to the surface of both the lower mold or the upper mold and the lower mold, and a convex edge is formed around the elastic body to surround the periphery of the tile material at the time of press molding, and to release the tile at the time of mold release. Since the periphery of the molded body is collapsed, the elastic body is compressed when pressurized, and the elastic body expands at the time of mold release and collapses around the tile molded body, and the components of the tile raw material are not uniform, In addition, the above-mentioned collapse is not uniform, and varies in all the tiles, so that brick-like tiles can be obtained without any processing in a later step.

なったのである。Further, since the elastic body is made of rubber and has a hardness of 65 to 85 degrees as described above, if it is harder than this, deformation is small and pressure cannot be stored, and collapse can occur. If it is softer than this, the required hardness of the mold will not be obtained, and the elastic body will be crushed or torn, or it will flow and the tile molded body will be distorted. Therefore, by setting the hardness to 65 to 85 degrees, the tile can be obtained in the same manner as in the related art, and a tile having a variation in which only the periphery has collapsed can be obtained.
