JPS5952044B2 - Molding device for tiles with protruding surfaces - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tile molding device having anti-slip protrusions.

Traditionally, tiles with protrusions like the one described above have been used as tiles laid in underground passages, building entrances, etc., but the protrusions have an area of about 1/20 of the main body, and there are nine of them. Normally, the sole of the shoe is supported on the protrusion without touching the surface of the shoe body, but since the protrusion is a smooth surface, a reliable anti-slip effect cannot be expected, and Since the protrusion and the protrusion are of the same color, it is difficult to identify their existence, which causes the protrusion to warp and trip over the protrusion.

The present invention aims to provide a tile molding device that can eliminate the above-mentioned drawbacks, that is, it has an upper mold that can be raised and lowered, and a recess formed on the surface for loading raw materials for molding protrusions. It consists of a lower mold that is movable up and down within the mold, and the recess of the lower mold is characterized in that its bottom is formed with an elastic layer made of an elastic material.

The embodiments shown in the drawings will be described below.

1 is an upper mold, and 2 is a lower mold, both of which are movable up and down, and the lower mold has nine recesses 3 formed at approximately equal intervals on its surface for forming protrusions.

An elastic layer 4 is formed by attaching an elastic material such as rubber or synthetic resin to a suitable thickness at the bottom of the recess 3.

Reference numeral 5 denotes a mold, and 6 a raw material box, which slides on the upper surface of the mold in the direction of the arrow to charge the raw material into the mold hole.

FIG. 1 shows a molded tile, where 7 is the main body and 8 is a protrusion.

Next, the molding operation will be explained.

The lower mold 2 is lifted up and held so that its upper surface is flush with the upper surface of the mold 5, and the raw material for forming the protrusion, that is, the powder colored white, for example, which is different in color from the main body raw material, is placed in the raw material box 6. The raw material is loaded into the recess 3 by filling the granular china clay raw material and passing it through the upper surface of the lower mold, and then the lower mold is lowered and the upper surface of the lower mold and the mold form a mold hole 5' into which the main raw material is introduced. On the other hand, the raw material for the protrusion is taken out from the raw material box 6 and filled with raw material for molding the main body.

The raw material for the main body is a powdered china clay raw material that is different in color from the raw material for the protrusions, for example, colored black.

Then, in the same way as above, slide the raw material box over the top of the mold to form the mold hole 5.
After loading the raw material into the container, the upper mold is lowered and the raw material is pressurized as is known in the art.

The tile molded in this way has a black main body 7 and a protrusion 8.
The protrusions are clearly marked in white, making it obvious to pedestrians at a glance.

Therefore, there is no fear of accidentally hitting the protrusion without noticing the existence of the protrusion.

Furthermore, since a material different from that of the main body is charged into the recess 3 in advance, there is no risk of mixing with the main material when pressed by the upper mold, and the bottom of the recess 3 is formed with an elastic layer 4. The particles with high hardness in the raw material for the protrusion are not crushed or pushed into the protrusion, but are bitten into the elastic layer and are molded as they are.

Therefore, the protrusion is formed to have an uneven rough surface, and the anti-slip effect can be further improved.

As described above, in the present invention, the protrusions are different in color from the main body, and the protrusions are molded to have a rough surface with irregularities, so that an effective tile with protrusions can be provided.
