Problems to be Solved by the Invention> However, in the conventional method for producing an inorganic cured body, there are the following problems, particularly when pressure forming a green board or a cross wire proboscis. ■ In order to impart plasticity to the material, if a large amount of thickener is added or if the water ratio is high, the viscosity or fluidity will increase and the material will easily adhere to the cutting die during mold release. ■ Particularly when a mold has a fine or deep pattern, such as a stone grain pattern, the material often sticks to the mold, and mold release oil is used to prevent the material from sticking. In many cases, it is not possible to prevent it from adhering to the mold. ■ Even if the material of the mold is changed to one with high m-type properties, if the material has high viscosity, it will often stick to the mold. ■ There are ways to lower the water ratio, but there is a problem that lowering the water ratio reduces moldability. ■ Even if the raw material has low viscosity, such as a molded product made by the papermaking method, if the thickness is uneven, if there is a deep pattern, or if it is large in size, pressure may be applied locally and cause adhesion. There is. Means for Solving the Problems〉 In order to solve the above problems, the method for releasing an inorganic molded article of the present invention has a structure in which a kneaded material made of a hydraulic inorganic composite is pressurized using a mold. In a mold release method for an inorganic molded body that is molded and then shaped into an M-shape from the mold, the above-mentioned mixed material is placed and the contact area of the kneaded material of the press receiver and the groove receiver of the mold is made to be air-permeable. The method is characterized in that the molded product is released from the mold while being suctioned toward the receiving portion through the breathable material. The present invention will be explained in detail below. Here, in the present invention, the inorganic molded body generally refers to cement,
A hydraulic inorganic composition containing gypsum as the main raw material and various other ceramic materials such as silicic acid raw materials, calcareous raw materials, reinforcing materials, aggregates, water-reducing materials, thickening materials, etc., as appropriate depending on the purpose, is prepared using a paper-making method.

! M) can be exemplified. In the present invention, the molding mold refers to a material obtained by kneading a hydraulic inorganic composition whose main raw material is cement, gypsum, etc., or a green plate or kneaded material that is primarily formed into a plate shape after mixing and kneading, into a predetermined shape. For example, it is used in pressure molding methods for ceramic materials such as flat press method and roll press method. In the present invention, the receiving part refers to a part that serves as a press receiving part when pressurizing the kneaded material using this mold. The contaminant-contacting part of the receiving part refers to the part that comes into direct contact with the bottom of the molded object, which is the object to be shaped, and causes the molded metal to be released from the mold while being sucked in the direction of the receiving part. In the present invention, the molded article is released by using at least a part of the above-mentioned air-permeable member to form the contact portion with the contaminant. Using a receiving part having a kneaded material contacting part made of an air permeable material as described above, the magic material is placed on the kneaded material contacting part, and after pressure molding, suction is performed using a separately provided suction pump, and a molded product is formed. is attracted toward the receiving part, making it easier to release the mold from the mold. Note that it is also possible to apply the present invention even when the breathable material and the molding mold are arranged oppositely, that is, the molding mold is arranged at the bottom and the breathable material is arranged at the top. A mold release process using a receiving part having a crosstalk contact part made of an air-permeable material will be described next with reference to FIGS. The receiving part 13 having the kneaded material contacting part 12 on which the kneaded material 11 is placed is transported to the pressing position of the mold 14 whose inner surface is coated with mold release oil. O Next, the mold 14 is lowered and pressure molding is performed at a predetermined pressure. O After pressure molding, immediately before raising the mold 14 upward, suction is applied using a suction pump (not shown) to remove the kneaded material contact portion 12.
The molded body 15 is attached to the side, and then the mold is released while being sucked.
