Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a method for forming a fine uneven pattern (for example, two grooves in width and three grooves in depth) on both surfaces of a wet green material for splitting into two parts.

Since a wet green material is generally formed by an extrusion method, the unevenness formed on the front or back side is limited to a TIH shape along the extrusion direction.

Therefore, it has been considered difficult to form a complex and delicate human uneven pattern.

In order to improve and eliminate these conventional drawbacks, the present inventors developed press molding using a glaze press mold for dry molding.
ft was tried, but no satisfactory results were obtained in any case. In the case of press molding using the right front mold, the extrusion mold absorbs the moisture contained in the wet green material, and when demolding, the pressure of the wet material [TII] was damaged. In the case of full use, 1 hard rubber + 60 hard J circles of rubber type is too high for the hardness of the wet green material (water content 23 to 25%), so even if the pressure is 0, VC is the convexity of the hard and negative rubber. Vertical compression and horizontal expansion do not work on the parts, and the wet dough is secretly hidden and cannot be removed from the mold.

The present invention is based on the above-mentioned method of forming irregularities of fibers obtained through repeated trial and error. To provide a method for forming a complex and delicate uneven pattern on both surfaces of a wet-type raw material for splitting into two.

The present invention will be described below based on drawings showing embodiments thereof.

As shown in Fig. 1, both surfaces 1a and 1blc of the wet fabric material 1' for halving are pressed with a suitable elastic soft material having a constant rubber hardness of 1''!lr. By pressing 2 and 2 times, the entire delicate uneven pattern is formed.

Two: 'j'l jJ warm and wet fabric 1', moisture content 23
It is in a state of ~25%, and is divided into two parts for drying, glazing, and firing, and each becomes a tile. The planned dividing surface of the wet green base material 1' for splitting into two is the back surface of the tile in the case of splitting force, but it facilitates the splitting work and also allows the sole to be formed at the time of splitting. In order to achieve a better VC than that obtained, multiple through holes 6°6, . . . are bored at equal intervals along the planned dividing plane during extrusion molding. Note that 4 indicates the peripheral edge of the plane to be divided. Prior to forming the uneven pattern, the through holes 6, 6. . . . Insert the through hole 6 inwardly into the hole i'HJ+3
+... or j; There are 11 people.

The wet green material 1' is pressed against the opposing pressure pads! 2 and 2 are fixed at 11゛j orthogonal to the direction of suppression of the press die 2, approximately in the middle of the trajectory in which they advance and retreat in order to perform the suppression operation.

Is there rubber on both inner surfaces of both press molds 2 and 2? 1ft! If
Surface layers 2a and 2b made of an elastic soft material (for example, elastic rubber, synthetic rubber, synthetic resin, etc.) having a hardness of 30 to 50 degrees or a hardness comparable to this hardness are provided, respectively. Each press 2a' of both surface layers 2a and 2b.

2b' has 11% 2m+n high 2-striped convex strips 7 or multiple fallen trees arranged to form a decorative uneven pattern.

When pressing molds 2 and 2rj1 are pressed 2a', 2b' or 1r-j1, they come into contact with and press both surfaces 1a and lb of wet green dough 1'. As shown in Fig. 2, the valleys and convex lines 7, 7, -(
r: l, 1j (As mentioned in 1, since it is somewhat more flexible than the wet green material 1', the press-fit resistance P to the wet green material 1' during compression)
Due to the reaction force caused by K, it receives a pressure t+6 that is opposite to the direction of suppression F, and expands in a direction perpendicular to its length direction. Therefore,
Four stripes having shapes corresponding to the ridges 7 after deformation are formed on the drawing surfaces rB+1a and 1b of the wet green material 1'. When demolding the double pressing die 2.2, each of the protrusions 7, 7.・・・
・In order to restore the original shape, the tile base material with the delicate uneven pattern corresponding to the push walls 2 a' and 2 d is restored without damaging the four stripes formed on both surfaces 1 a and ib. That's what you get.

The first surface 21a is returned to the back side of the feeding mechanism 10 at step 1, and the next itchy-type raw material 1' is loaded and stands by.

The wet green material 1', which has been kept identified, is pressed simultaneously from both sides with the press molds 2, 2, and becomes a tile material material 1 with delicate unevenness formed on both sides. After the pressing mold 2.degree. 2 and the suppressing material 18a are released, the frame 15Vi is pushed out to the external fixed position. Thereafter, the box 21 loaded with the DtJ wet green material 1' is pushed out and transferred to the tile material 1i on the wall surface 21b, and transferred to the other wall surface 21a.

When used, it is not a matter of course that the appropriate history is added to the shape and shape.

From the above explanation, it is clear that according to the method of forming a wet fabric for unexploded Lv1, which is divided into two parts, in a delicately uneven pattern, the wet fabric can have a textured uneven pattern that was conventionally impossible. 1171 can now be simply formed.

In addition, the equipment is not limited to the one shown in this example, but can also be used with a conventional simple press.
It can be said that it is a groundbreaking and innovative development, such as being able to be implemented even in factories that require easy preparation.
