０は上型、１１は下型である。Such colored patterned ceramic plates have traditionally been formed by a method called the "dry press method," in which a mixed powder material of a colored material and a base material is piled up and filled into a lower mold for breath molding, and then pressed. has been done. However, this method has problems in that it is not possible to form an intentional colored pattern, and it is difficult to produce large ceramic sheets. Therefore, recently, a casting method using an apparatus as shown in FIG. 9 has been proposed and put into practical use in some cases (Japanese Patent Laid-Open No. 1-218803). This method connects three types of colored slurry injection channels 2, 3.4 in the middle of a base slurry casting channel 1,
When casting the base slurry, an appropriate amount of colored slurry is press-fitted from each colored slurry inlet 2.3.4 and forcibly mixed into the base slurry, so that the Heese slurry and the colored slurry can be mixed well in the cavity 5. This system is designed to generate a color pattern that is mixed with the following colors. In the figure, 6, 7° and 8 are storage tanks for collecting colored slurries of different colors, 9 is a casting port, and 1
0 is the upper mold, and 11 is the lower mold.
このようにして得られた成形品の表面には、第１０図に

。As shown in FIG. 10, on the surface of the molded product thus obtained, a colored pattern is formed in which the colored slurry draws streaks in the base slurry along the flow from the casting port 9. .

。[The invention tries to solve the problem! ! ! Title] However,
In the above method, the flow pattern of the base slurry and the colored slurry changes depending on the arrangement of the pouring port 9, and the color pattern formed changes accordingly. Therefore, in order to change the color pattern, it is necessary to prepare molds each having a different arrangement of the casting ports 9, which is a problem in that it takes time and cost. Therefore, as a method to freely change the color pattern, a method has been proposed in which the inner surface of the upper mold is coated with a color pattern in advance and the base slurry is cast into this mold. In order to prevent the color pattern in the upper mold from flowing during casting and causing the mold to collapse, it is necessary to lower the casting pressure, resulting in the problem of a long molding time.

たという権威をとる。In order to achieve the above object, the method of casting a colored patterned ceramic board of the present invention includes the steps of preparing a pair of upper and lower casting molds each having a casting opening in the center of the shaping recess of the lower mold. , a mixing step in which a plurality of colored slurries of different colors are mixed in a mixing drum equipped with stirring blades to form a color pattern; A step of pouring so that 60 to 85% of the internal volume of the mold is filled, and after closing the lower mold and upper mold, the base slurry is poured from the casting opening of the lower mold to form the colored pattern slurry and the base slurry in the mold. It has the authority of being equipped with a casting molding process that integrally molds.

鋳込みによって短時間で成形品を得ることができる。That is, in this invention, instead of forming a color pattern on a ceramic plate in a mold as in the past, the color pattern is formed by mixing a plurality of types of colored slurry in a mixing drum in advance. A predetermined proportion of the pattern slurry is filled into the lower mold, and after the mold is closed, the base slurry is poured from the casting hole provided in the center of the lower mold, and the colored pattern slurry is pushed up from the bottom to form the mold. be. According to this cast molding method, the colored patterned slurry is lifted upward without being deformed by the base slurry flowing in from the casting opening, so the patterned surface of the colored patterned slurry in the lower mold is lifted upward as it is. It will be pressed against the inner surface of the mold. Therefore, if this is removed from the mold, a molded product with a colored pattern formed on the surface can be obtained, and a colored patterned ceramic plate can be obtained from the bottom of the hole. In this cast molding method, in order to change the color pattern, it is only necessary to change the order of adding the colored slurry into the mixing drum, the stirring conditions, etc., and the color pattern can be easily changed. Further, even if the base slurry is cast under high pressure, the uniform pushing effect of the color pattern slurry is not impaired, so the color pattern does not become deformed. Therefore, a molded product can be obtained in a short time by high-speed casting.

型の下型３１内に導入する。FIG. 1 shows an example of a mixing drum used in the present invention. In the figure, 20 is a cylindrical mixing drum with a bottom, and a stirring blade 21 is attached therein. Further, an opening 22 with an opening/closing shutter (not shown) is provided at one location on the bottom surface of the mixing drum 20, and a shooter 23 extends diagonally downward from this opening 22. 24, 25
．． Reference numeral 26 denotes a colored slurry injection nozzle, which supplies three types of colored slurries A, B, and C of different colors, respectively. Therefore, the colored slurries A, B, and C are charged into the mixing drum 20 in an appropriate order from the three colored slurry injection nozzles 24, 25, and 26, and are stirred by the stirring blade 21. A color pattern is formed by mixing the three colors. Then, the opening 22 at the bottom is opened and the colored pattern slurry is introduced from the shooter 23 into the lower mold 31 of the casting mold as described below.

ている。As shown in FIG. 2, the casting mold used in this invention consists of an upper mold 30 and a lower mold 31, and the upper mold 30 moves up and down by driving a hydraulic cylinder (not shown). ing. A casting port 32 is opened at the center of the recess in the lower mold 31 and communicates with a material supply pipe 34 extending from a material supply source (not shown) via a flow path 33.
前記混合ドラム２０は、上記鋳込み型に対して進退自在
に配置されており、鋳込み型に向かって前進した状態で
、上型３０と下型３１の間にシュータ−２３の先端が入
り込むようになっている。The mixing drum 20 is arranged to move forward and backward with respect to the casting mold, and the tip of the shooter 23 enters between the upper mold 30 and the lower mold 31 when the mixing drum 20 moves forward toward the casting mold. ing.
この状態で、前記混合ドラム２０内で混合して得られた
色模様泥漿４０を、シュータ−２３から流下させて下型

要である。すなわち、充填量が上記範囲を下回ると、鋳
込み時のベース泥漿の流入量が多くなるため、色模様泥
漿４０が受ける流れの影響が大きくなる崩形しやすい。In this state, the colored pattern slurry 40 obtained by mixing in the mixing drum 20 is allowed to flow down from the shooter 23 and is filled into the recessed portion of the lower mold 31. At this time, the filling amount needs to be 60 to 85% of the internal volume of the lower mold 31. That is, if the filling amount is less than the above range, the amount of base slurry flowing in during casting will increase, and the colored pattern slurry 40 will be more susceptible to the influence of the flow and will be more likely to collapse.
逆に、充填量が上記範囲よりも多くなると、鋳込み時の
ベース泥漿の流入量が少なくなって成形が不充分となる
。このようにして下型３１内に色模様泥漿４０を充填し

品が得られる。そこで、この成形品を焼成すれば、色模
様付セラミックス板を得ることができる。On the other hand, if the filling amount exceeds the above range, the amount of base slurry flowing in during casting will be small, resulting in insufficient molding. After filling the lower mold 31 with the color pattern slurry 40 in this manner, the mixing drum 20 is moved back to remove the shooter 23 from the space between the upper and lower molds 30,31. In this state, the upper mold 30 is lowered and the mold is clamped, as shown in FIG.
A base slurry 41 is poured from a casting port 32, and the inner surfaces of an upper mold 30 and a lower mold 31 absorb moisture in the colored pattern slurry 40 and the base slurry 41, and the colored pattern slurry 40 and the base slurry 41 are integrally molded in the mold. At this time, as shown in FIG. 4, the base slurry 41 lifts the colored pattern slurry 40 upward while spreading in the left and right directions within the mold. Next, this is removed from the mold, and a ceramic molded product with a flat base part 41' derived from the base slurry 41 spread out inside the colored pattern part 40' derived from the colored pattern slurry 40 as shown in FIG. is obtained. Therefore, by firing this molded product, a colored patterned ceramic plate can be obtained.

模様の仕上がり具合を予想することができる。そして、
上記色模様のパターンを変えるには、混合ドラム２０内
への着色泥漿Ａ、Ｂ、Ｃの投入順序、撹拌条件等を変化
するだけでよく、簡単に色模様を変えることができる。Therefore, according to this molding method, the colored pattern slurry 40 is
Because the base slurry 41 flowing in from the casting port 32 lifts the molded product upward without deforming it, the patterned surface of the patterned slurry in the lower mold 31 is pressed directly against the inner surface of the upper mold 30, changing the color of the molded product. It becomes a pattern. Therefore, the finish of the color pattern can be predicted at the time when the color pattern slurry 40 is filled into the lower mold 31. and,
To change the color pattern, it is only necessary to change the order in which the colored slurries A, B, and C are introduced into the mixing drum 20, stirring conditions, etc., and the color pattern can be easily changed.
また、撹拌羽根２１の正転。In addition, the stirring blade 21 rotates normally.
逆転を繰り返すことにより、より細かな色模様を生成さ
せることもできる。また、ベース泥漿４１の鋳込みを高
圧で行っても、色模様泥漿４０の色模様が崩形すること
がないので、高圧鋳込みによって短時間で成形すること
が可能となる。By repeating the reversal, it is also possible to generate a finer color pattern. Moreover, even if the base slurry 41 is cast under high pressure, the color pattern of the colored pattern slurry 40 will not be distorted, so that high-pressure casting enables molding in a short time.
なお、この発明に用いる各着色泥漿Ａ、Ｂ、Ｃおよびベ

。Note that the colored slurries A, B, C and the base slurry 41 used in this invention may be any conventionally known slurry, but it is preferable to use ones that have similar shrinkage rates during firing. . That is, if the firing shrinkage rates of the two are significantly different, this will cause minute voids and cracks to occur at the boundary between the base portion and the colored pattern portion after firing.
また、着色泥漿の種類は、２種類以上であれば何種類で
もよい。そして、いずれかの着色泥漿がベース泥漿と同
一のものであってもよい。Further, the number of types of colored slurry may be any number as long as it is two or more types. And either colored slurry may be the same as the base slurry.

る。Alternatively, the color pattern slurry 40 is transferred from the mixing drum 20 to the lower mold 3.
1, as shown in FIG.
If the sieve 47 is placed above the sieve 47 and is vibrated to scatter it on the surface of the colored pattern slurry 40, the color pattern and the spotted pattern will be combined by casting the base slurry 41 in the same manner as in the above embodiment. A molded product can be obtained.
