型を提供するものである。However, the above-mentioned conventional molding method of molding a molded article using a potter's wheel requires skillful skill of a maker, and the production yield is poor. Since it is a one-piece production that is greatly influenced by the craftsmanship, it takes a lot of time and effort, and the production efficiency is low. Further, in the above-described conventional method of obtaining a molded product using a split mold, it is difficult to release the molded product from the mold, and the production efficiency is low. Therefore, the present invention solves the above-mentioned conventional inconveniences, and the mold release can be performed quickly and reliably without the need for skilled technology. For example, the production efficiency is suitable for mass production without much time and labor. It is intended to provide a molding method and a molding die of a molded article made of an inorganic hydraulic material having a high yield and a good yield.

When the raw material 2 adhered to the mold is dried without dividing the split mold body 1, the split mold body 1 itself is formed of gypsum and exhibits water absorption, so that the inner surface of the split mold body 1 has a desired thickness t. Moisture contained in the attached raw material 2 is split mold body 1
Is absorbed by gypsum and dried, and the outer volume of the molded article S is shrunk. Then, a gap k for mold release is formed between the inner surface of the split mold body 1 and the raw material 2. Thereafter, after the drying process is completed, the mold is separated into a plurality of mold components 1A and 1B in the figure, and two gaps are formed between the inner surface of the mold body 1 and the raw material 2. The mold release is quickly and reliably performed through k, and a molded product S is obtained. Since the gap k is formed between the inner surface of the split mold body 1 and the raw material 2 in the molded product S thus obtained, the molded product S is smoothly released from the mold without adhering to the split mold body 1. No uneven surface is formed on the surface of the molded product S, the smoothness is high, and no post-processing such as surface treatment is required. Thereafter, the molded product S is glazed and then transferred into a firing furnace, where it is fired at a desired firing temperature to obtain a finished product.

In this embodiment, a hollow split mold body 1 is formed of two upper and lower molds having a rectangular parallelepiped outer shape using metal or wood. It is formed by members 1A and 1B. A water absorbing member 10 made of an inorganic sintered porous material such as aluminum oxide is fixed to the inner surface of the split mold body 1 and flows into the split mold body 1 to have a desired thickness t on the inner surface of the split mold body 1. Moisture contained in the raw material 2 of the inorganic hydraulic material to be adhered can be absorbed in the porous pores formed in the water absorbing member 10 made of the inorganic sintered porous material. Then, by drying, the outer volume of the raw material 2 attached to the inner surface of the split main body 1 is reduced, and the gap k formed between the inner surface of the split main body 1 and the raw material 2 is reduced.
The mold S is quickly and reliably released from the mold. The method of forming the molded product S using such a split mold body 1 is the same as described above.
