Description of the Related Art Heretofore, in order to increase the adhesive strength of a tile to a wall surface or the like, there has been provided a tile having a back foot having an uneven shape on the back surface side of the tile. A so-called rubber mold 14 has recently been used in place of the steel mold as a mold for molding this type of tile with back feet. This is because the rubber mold 14 has various advantages such that it can be molded at almost room temperature and the mold cleaning cycle is twice as long as that of the steel mold.

When the concave-convex shape for forming the foot is provided on 4, the molding pressure acting on the convex portion 15 is higher than the molding pressure acting on the concave portion 16, and as a result, the filling amount of the kneaded clay and the filling density thereof are convex. The portion 15 was higher than the concave portion 16. For this reason, the water absorption rate of the glaze applied to the tile surface after molding is biased corresponding to the convex portion 15 and the concave portion 16 of the back foot portion, and there is a portion corresponding to the back foot portion of the surface of the fired product. There was also a problem that a so-called back footprint was generated by being recessed from the part corresponding to the dovetail groove. Further, since the filling amount and the filling density of the kneaded material are different between the concave portion 16 and the convex portion 15 of the back foot, there is a problem that the bending strength at this boundary portion is lowered and a crack occurs.

Since the shape is such that it protrudes toward the back surface side of the back surface shape of the portion, the amount of shrinkage of the recessed portion increases during molding and pressing. Therefore, even if the depth of the recess is reduced, it is possible to obtain a predetermined back foot height. Further, since the depth of the concave portion can be reduced, it is easy to make the filling amount of the kneaded material uniform, and it is easy to charge the kneaded material. Furthermore, since the amount of shrinkage deformation of the rubber part at the convex and concave parts of the surface of the rubber mold can be made uniform, the filling density of the kneaded material can be made uniform, and uneven glaze caused by uneven molding pressure, Footsteps can be prevented.

FIG. 1 is a cross-sectional view showing a molding apparatus for molding a tile with back feet according to the present invention. In the molding apparatus 1 shown in FIG. 1, the upper surface of a lower mold 3 in a frame mold surrounded by a frame body 2 is filled with a kneaded clay 4 as a tile raw material, and an upper mold 5 is loaded in the frame mold. It is a device that pressurizes and compresses to form a tile base with backing. The lower mold 3 is for pressing the back surface side of the tile base material, and a rubber mold part 7 is coated on an upper part of a base part 6 made of steel.

出する突出部１２が形成されている。The front surface of the rubber mold portion 7 is for forming the ridge 8 and the foot portion for forming the dovetail groove portion of the back foot in order to form a plurality of back feet of the ridge on the back surface of the tile base material. Concave portions 9 are alternately formed at regular intervals. On the back surface portion 10 of the rubber mold portion 7 corresponding to the recessed portion 9,
A protruding portion 12 that protrudes further toward the back surface side than the back surface portion 11 corresponding to the ridge portion 8 is formed.

易なり、坏土のチャージングがし易くなる。When the backing tile is molded by using the molding apparatus having the above-mentioned structure, the back surface portion 1 corresponding to the recessed portion 9 is formed.
Since 0 is the protruding portion 12 protruding to the back surface side, the amount of contraction corresponding to the concave streak portion 9 becomes large. Therefore, even if the depth of the recessed portion 9 is small, it is possible to form a back foot having the same size as the conventional one. Therefore, the filling amount of the kneaded material is easily made uniform, and the kneaded material is easily charged.

The amount of shrinkage and deformation of the rubber portion in step 1 will be made uniform, and the packing density of the kneaded material can be made uniform.
