Abstract

PURPOSE:To provide a tile forming mold capable of forming a dovetail grooved recess on a rear face of a tile simultaneously with molding of the tile. CONSTITUTION:In a tile forming mold, either a lower mold 1 or an upper mold 4 or both of them are placed in proper positions in the tile mold, and a proper elastic body is provided such that a head part 7A opens widely when the upper mold 4 and the lower mold 1 are closed so as to pressure porcelain powder, and a reversed trapezoid i.e., a dovetail grooved recess 6B is formed on a rear face of a tile at molding the tile.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a die for molding a tile, and more specifically, an object thereof is to form a dovetail groove-like recess on the back surface of a tile simultaneously with the molding of the tile.

[0002]

2. Description of the Related Art Conventionally, in order to install a tile on a wall surface or the like, a dovetail groove-like recess is formed on the back surface of the tile from the viewpoints of peeling and workability, and an appropriate cut and raised portion is formed on an iron plate or the like. The dovetail groove portion of the tile is slidably fixed to the cut-and-raised portion, and the tile has a dovetail groove concave portion on the back surface. After the trapezoidal nest was positioned, the nest was taken out together with the tile after pressure molding, and the nest was manually slid and removed from the tile.

[0003]

Therefore, it is necessary to remove the inserts from the tiles one by one and place them in the mold, which is troublesome and costly. Also, as shown in FIG. 4, dovetail groove-shaped recesses are formed on both sides, and after molding, they are divided into two with an appropriate wedge etc. to obtain tiles with a rough surface, on both sides (up and down during molding). It was not possible to position the nest at the same time.

For this reason, there is a strong demand for a means capable of forming dovetail-shaped recesses on the back surface of the tile simply and quickly at the same time as tile molding, and simultaneously forming dovetail-shaped recesses on both sides of the tile.

Therefore, as a result of repeating day and night thinking and error, the inventor of the present invention has accomplished an invention of interposing an elastic body which deforms into a dovetail groove shape by applying pressure. .

[0006]

In order to achieve the above-mentioned object, the present invention is to mount a tile molding die on either the upper die or the lower die, or both the upper die and the lower die. A tile that can be molded by inserting an appropriate amount of porcelain powder into the lower mold cavity and then closing the upper mold and lower mold to pressurize them so that the tip of the appropriate elastic body expands into an inverted trapezoidal cross section. This is a mold for tile molding, which is characterized by forming a dovetail-shaped recess on the back surface.

[0007]

Therefore, when an appropriate amount of porcelain powder is put into the lower mold and pressure is applied by the upper mold, the tip of the elastic body expands into an inverted trapezoidal cross section, thus forming a dovetail-shaped recess on the back surface of the tile to be molded. It will be able to be formed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a partially cutaway sectional view of a first embodiment of the present invention, FIG. 2 is an external perspective view, and FIG. 3 is a sectional view at the time of pressurization.
The means of the present invention can be attached to either the upper die or the lower die, or both the upper die and the lower die among the tile forming dies, but here, the embodiment attached to the lower die will be described. That is, by inserting an appropriate amount of porcelain powder 3 into the recess 2 of the lower mold 1 and closing and pressing the upper mold 4 and the lower mold 1, the tip 5A of the appropriate elastic body 5 has an inverted trapezoidal cross section. It is a mold for tile molding capable of forming a dovetail groove-shaped recess 6B on the back surface 6A of the tile 6 that is thus molded. The tip end portion 7A of the plate-like elastic body 7 is expanded into an inverted trapezoidal cross section by the both side inclined portions 8A of the descending body 8 to form a dovetail-shaped concave portion 6B on the back surface 6A of the tile 6 to be molded (FIG. 7)) and the elastic body 5 is Example, if hardness of 50, such as urethane rubber
It is suitable that the angle is between 90 degrees and 90 degrees, and the recess 9
It is fixed to A by a bolt 11 so that it can be held by a pair of fixing pieces 10 and 10 with a slight inclination toward the inside.
The descending body 8 is biased upward by a compression spring 12 and its movable distance is regulated by a bolt 13 slidably held by a base 9.

Therefore, if an appropriate amount of porcelain powder 3 is put into the lower part 1 and pressurized by the upper die 4, the descending body 8 resists the compression spring 12 through the porcelain powder 3 as shown in FIG. The tip 6A of the elastic body 7 is pushed down to expand the tip 7A of the elastic body 7 into an inverted trapezoidal shape, so that the tile 6 having the dovetail-shaped recess 6B on the back surface 6A as shown in FIG.
As shown in FIG. 8, the dovetail-shaped concave portion 6B can be slidably fitted to the cut-and-raised portion C of the iron plate B attached to the wall surface A as shown in FIG.

Since the present invention can be mounted on both the lower mold and the upper mold with, for example, bolts (not shown), the tile 6 having the dovetail-shaped recesses 6B on both sides as shown in FIG.
It is also possible to mold (the dovetail groove-shaped recesses are arranged vertically when molding), and to divide the surface with an appropriate wedge D etc. to inexpensively manufacture the popular tile 60 of recent years. .

Another embodiment is shown in FIG. 5 and FIG.
FIG. 5 shows the descending body 8 in which the inclined portions 8A on both sides are linear, and FIG. 6 shows the elastic body 7 provided vertically. The other structures are the same as in the above-described embodiment.

Further, another embodiment is shown in FIG. 9, in which an appropriate amount of porcelain powder 3 is put into the recess 2 of the lower mold 1 and then the upper mold 4 and the lower mold 1 are formed.
By closing and pressurizing, the both end portions 14A of the elastic body 14 having an inverse U-shaped cross section having an appropriate width dimension are expanded into the inverted trapezoidal shape through the movable piece 16 by the both side inclined portions 15A of the push-up body 15. Tile 6 that can be cast and thus molded
The dovetail-shaped recess 6B can be formed on the back surface 6A of the above.

Further, it goes without saying that the method of mounting the elastic body, the fixing means, the size and the number of the elastic body of the present invention can be arbitrarily selected according to the size of the tile to be molded.

[0015]

Since the present invention has the configuration described above,
Simultaneously with molding, a dovetail groove can be formed on the back of the tile, and the elastic body is restored to its original state when the mold is opened, so only the molded tile can be taken out, and continuous work can be carried out quickly and sequentially. Therefore, the tile cost can be reduced.
