Description

[Detailed description of the invention] The present invention is a removable mounting structure between a rod-shaped mold piece that fits into the frame of the tile mold body and forms the bottom surface of the tile, and a substrate that supports the rod-shaped mold piece. It is related to.

Conventionally, in tile molding, the material used is viscous, so even if the mold is baked, each part of the mold wears out quickly, and if molding continues in a worn state, the commercial value of the product decreases. Therefore, it is necessary to replace worn molds as soon as possible, but as a practical matter,
The mold is quite expensive, and on the other hand, the wear of the mold progresses in some parts, so even if there are some problems with strength, it is possible to replace the worn parts by combining the molds instead of integrating them. I'm trying to replace them one by one.

However, in this case, due to the structure of the mold body that makes up the mold frame, it is possible to replace parts while maintaining sufficient strength and precision even with a combination mold. In the case of a medium mold that fits into a frame to form the bottom surface of the tile, that is, a medium mold that has a large number of rod-shaped mold pieces for forming the bottom surface of the tile standing on a substrate at intervals between the frame parts, the rod-shaped mold pieces are long and the rod-shaped mold pieces are long. Since the mold piece is supported in a cantilever manner with respect to the board, it is particularly difficult to achieve positioning and fitting accuracy between the frame and the tip of the rod-shaped mold piece using mounting methods such as screw tightening or tapered fitting. Moreover, in this tile molding mold, there was a problem in that the corners of the rod-shaped mold pieces were most likely to wear out, and the parts needed to be replaced at the earliest.

The purpose of the present invention is to eliminate the above-mentioned drawbacks of the conventional tile molding mold by providing a tile molding mold that allows the rod-shaped mold piece to be easily replaced with respect to the substrate while ensuring accurate positioning and fitting. It's about doing.

Next, the configuration of an embodiment of the present invention will be explained with reference to the drawings.

This example is a case of a mold for wet tile molding using an extrusion molding machine, and the center of the mold body 1 is attached to the dough extrusion port 101 of the extrusion molding machine as shown in FIGS. 2 and 3. A rectangular opening 2 having a size of eight tiles is formed in which the cross-sectional shape of the tiles in the thickness direction is arranged in two rows of four tiles each, and a frame portion 3 of two tiles is formed on the surface of the opening 2. A frame body 4, in which four parts are formed, is attached via bolts 5, and a suspension plate 6 and bolts 7, 8,
Hanging plates 10 are attached via nuts 9 parallel to the back surface of the mold body 1 at regular intervals to allow smooth flow of the dough.

Further, on the hanging plate 10, there are hanging beads 11 that form the bottom surface of the tile by dividing each frame portion 3 of the frame body 4 into two vertically.
However, the square hole 12 of the hanging plate 10 is formed by wire cutting (electrical discharge machining), and the square end 13 of the hanging ball 11 is formed by polishing at the support side. It is mounted so that it cannot rotate by a screw 14, and cannot move in the axial direction by a set screw 14.

The molds 15 combined in this way are attached to an extrusion molding machine to manufacture tiles. In other words, from the mold 3 attached to the dough extrusion port 101 of the extrusion molding machine shown in FIGS. The clay in the molding machine is continuously extruded into a two-tier array of tiles 102 with an external shape determined by the frame 4 and the hanging balls 11 as shown in FIG. 1 in a yo-can shape as shown in FIGS. , the extruded tile 102 is connected to the wire 1 according to the product dimensions.
03, and after firing the cut tile 102, the two-tier arrangement is divided into halves to produce the product. If the corner of the tip of the hanging ball 11 is worn out, it should be removed from the extrusion molding machine. Mold 15
Loosen the bolt 8 to remove the hanging plate 10 from the hanging plate holder 6, loosen the set screw 14, remove the worn hanging ball 11 from the hanging plate 10, and insert a new hanging ball 11 into the square hole 12 where it was removed. When the square end portion 13 of the new hanging ball 11 is inserted, the square end portion 13 of the new hanging ball 11 fits into the square hole 12 of the hanging plate 10 in a static state, so that the hanging plate 1
The hanging ball 11 is attached to the mold 15 with an accuracy corresponding to the electrical discharge machining accuracy of the square hole 12 and the polishing accuracy of the square end 13. As a result, even if the hanging ball 11 is replaced, the accuracy of the mold 15 is maintained. In this case, the precision with which the hanging balls 11 are attached to the hanging plate 10 is the same as before the hanging balls 11 were replaced.

In addition, in this example, mold 1 in the case of wet type
5, but the same can be said of the rod-shaped mold pieces inserted into each tile separate frame in the dry type.

Next, the effects of the present invention will be explained.

According to the present invention, a hanging plate attached to a mold body having a plurality of frames for tile forming, for example, a mold body 1 to which a frame body 4 is attached, has a plurality of frame parts arranged in the mold body. Forming a fully square hole machined at right angles that can be statically engaged with the square end part machined at right angles formed at the support side end of the rod-shaped hanging ball that is cantilever-supported by the hanging plate, and
The tile forming mold is characterized in that the square hole and the square end are removably screwed together.

As a result, this invention enables the positioning of all hanging beads with high precision without requiring any adjustment in tile molding molds that cantilever support long rod-shaped hanging beads and have a limited longitudinal dimension of the supporting part. In addition to being able to take out the hanging balls, it also has the effect of making it easy to replace parts of the hanging balls.
