Furthermore, since a divided perforated plate having holes of different diameters depending on the passage resistance is used, a desired perforated plate can be obtained by rearranging the divided perforated plates. Therefore, the number of types of perforated plates can be reduced compared to the conventional method.
また、押出用口金背面に直接設けることにより
多孔板の効果が顕著に発揮され、口金と同時に脱
着ができるため、取換操作が容易にできる。 Further, by providing the porous plate directly on the back surface of the extrusion nozzle, the effect of the perforated plate is significantly exhibited, and since the nozzle can be attached and removed at the same time, replacement operations can be facilitated.

FIG. In this embodiment, the extrusion device 1
The die 5 is composed of an extrusion die 3 having a discharge groove 2 and a plurality of earth supply holes 4, and a perforated plate 6 provided on the back side of the extrusion die 3 of the die 5. The perforated plate 6 has a rectangular division part 7 and a base part 8.
The inner diameter of the hole 9 in the divided portion 7 is made smaller than that of the hole 10 in the base 8 to change the opening ratio. The thickness of the perforated plate 6 is preferably 1 mm or more, and is determined in consideration of the viscosity of the molding material, the inner diameters of the holes 9 and 10, etc. Also, the outer diameter of the perforated plate 6 is determined by the die 5.
It is preferable that the outer diameter is the same as that of the outer diameter of the outer diameter. Further, the perforated plate 6 is preferably made of the same material as the dice 5, that is, metal, but is not limited to metal. Since the perforated plate 6 is pressed against the die 5 by the potted soil during extrusion, the perforated plate 6 can be constructed by simply fitting the divided portion 7 and the base portion 8 into each other.

B is a front view and a cross-sectional view, respectively, of other embodiments of the extrusion device of the present invention, viewed from the surface of the pot supply hole. In FIGS. 2, 3, and 4, the same members as those in the embodiment shown in FIG. 1 are given the same reference numerals, and their explanations will be omitted.

構成することもできる。 The embodiment shown in FIGS. 2A and 2B differs from the embodiment shown in FIG. 1 in that the shape of the dividing portion 7 is circular. When the shape of the divided part 7 is circular in this way, in order to simplify the positioning when the divided part 7 and the base part 8 are assembled, the positioning mark 1
It is preferable to provide marks 1 and 12 and perform positioning so that these marks 11 and 12 coincide. In the embodiment shown in FIG. 2, there is only one dividing section 7, but the dividing section 7 can also be constructed by concentrically dividing into a plurality of sections.

様の作用をさせることもできる。 The embodiment shown in FIGS. 3A and 3B differs from the embodiment shown in FIG. 1 in that the thickness of the dividing portion 7 is greater than the thickness of the base portion 8. By changing the thickness of the divided portion 7 and the base portion 8 in this way, it is possible to obtain a desired pressure distribution during extrusion of the clay. Therefore, assuming that the hole diameters of the dividing part 7 and the base part 8 are the same,
It is also possible to cause the perforated plate 6 to have a similar effect by changing the thickness of each.

使用する場合の自由度が大きくなる。 In the embodiment shown in FIGS. 4A and 4B, the first point is that the perforated plate 6 is constructed by widening the area of the divided portion 7 and combining the divided portions 7-1 to 7-7.
This is different from the embodiment shown in the figure. When the divided portion 7 is formed from a plurality of divided portions in this manner, the degree of freedom when using the divided portions 7-1 to 7-7 in other porous plates 6 increases, for example.

のような形状でもよい。 The present invention is not limited to the embodiments described above, and can be modified and modified in many ways. For example, in the embodiment described above, the shape of the dividing portion 7 of the perforated plate 6 is square or circular, but the shape is not limited to this, and any shape may be used as long as it can be divided.
