Description

[Detailed Description of the Invention] * Industrial Application Field The present invention relates to a press mold for forming the hook portion of a tile support plate that supports tiles.

*Problems to be solved by conventional technology and ideas This type of press mold has existed for a long time, but in these conventional press molds, the convex part of the upper mold and the concave part of the lower mold have a rectangular planar shape. Thus, a tile support plate as shown in FIGS. 6 and 7 is formed. However, the hook portion 1 in such a tile support plate
Since the length a is almost equal to the length b of the recess in the lower mold, when the tile support plate separates from the lower mold after pressing, the side edges 1' and 1' of the hook part 1 touch the end walls of the recess in the lower mold. There is a risk of damage from contact.

The present invention attempts to solve the above problems by improving the planar shapes of the convex portion of the upper mold and the concave portion of the lower mold.

*Means for solving the problems Hereinafter, means for solving the above problems will be specifically explained based on illustrated embodiments.

As shown in FIG. 1, the convex part 11 of the upper mold 10 and the recessed part 13 of the lower mold 12 in the press mold according to the present invention each have a trapezoidal planar shape, and the hook part 15 of the tile support plate 14 is bent. base 16
(See Figures 3 and 4)
7' forms one of a pair of parallel opposite sides of the trapezoid, and the one side 17, 17' forms the 1
It should be longer than the other side 18, 18' of the pair of opposite sides. That is, the above one side 1
7, 17' length is c, c', the other side 18, 1
If the lengths of 8' are d and d', then c>d and c'>d' (see Figure 1).

In addition, in order to prevent the hook portion 15 of the tile support plate 14 from being cut at the bent portion, the upper mold 1
The portions 19, 20, 19', and 20' of the hook portion 15 of the lower die 12 and the hook portion 15 are appropriately rounded.

* Effect Since the convex portion 11 of the upper mold 10 and the recessed portion 13 of the lower mold 12 in the press mold according to the present invention have a trapezoidal planar shape as described above, the hook of the tile support plate 14 formed using the press mold according to the present invention is The portion 15 tapers from the bent base 16 toward the tip edge 21, and the length e of the tip edge 21 is shorter than the length f of the lower die recess 13 at the position corresponding to the tip edge 21. (See Figure 3). Therefore, when the tile support plate 14 separates from the lower mold 12 after pressing, there is no risk that the side edges 15', 15' of the hook part 15 will come into contact with the end wall of the recess 13 in the lower mold 12, and the hook part 15 will be removed from the lower mold 12. It comes out smoothly from the recess 13 of the mold 12.

The tile support plate 14 formed by the press mold of the present invention is fixed to a substrate 22 in a building, etc., as shown in FIG. 5, and the hook portions 15, 15... support the tiles 23, 23... 24 is mortar filled in the joints.

* Effects of the invention As explained above, the press mold according to the invention has a trapezoidal planar shape for the convex part of the upper mold and the concave part of the lower mold, so that when the tile support plate separates from the lower mold after pressing, the side of the hook part The edge does not come into contact with the end wall of the recess in the lower mold, and the hook smoothly exits from the recess in the lower mold.
