2. Description of the Related Art Conventionally, for example, when a sanitary ware body is manufactured, a resin mold for pressure casting is used, and slurry is cast into the resin mold by applying pressure, and the meat is internally formed.
Later, the mold is removed to form a sanitary ware body, and the resin mold needs to have good communicating pores inside in order to evenly eject water and air when removing the mold. Conventionally, a mold is formed into a predetermined shape by pouring a resin into a case mold. In the conventional method of manufacturing a resin mold by pouring, the communication of pores formed in the resin mold is poor, and the internal density is low. And the thickness was also likely to be uneven.

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has been devised in view of the above problem. The purpose of the present invention is to provide a method for producing a mold, the gist of which is a method for producing a resin mold for pressure casting for pressure casting of slurry, wherein the resin mold has a surface coated with a resin of 100 μm or less. Is formed by stamping for each layer on a case mold and stacking the filler in a multilayer shape.

[Function] Since a filler obtained by mixing a filler into a sphere of 100 μm or less is stamped for each layer and stacked to form a multilayer structure, the porosity of pores formed therein is better than that of a conventional cast molding. Thus, a resin mold can be obtained in which pores are uniformly dispersed in the inside and water and air can be circulated well.

At the time of this production, first, a filler 3 to be the first layer 3a is filled in the upper surface of the case mold 1, and a bar 4 having a diameter of about 2 cm is used to move the bar 4 up and down. One layer 3a
Stamping and hardening. After that, the second layer 3b is
And the second layer 3b is stamped with a bar 4. Thereafter, the third layer 3c is filled in the upper portion, and the third layer 3c is also stamped with the bar 4.
In this way, each layer is stacked in a multilayer shape while being stamped with the bar 4 and sequentially stacked from the first layer to the second, third, fourth, fifth and sixth layers to produce a resin mold having a predetermined shape. I do.

The filler 3 is a sphere 5 of 100 μm or less.
0% is mixed with a filler such as aluminum hydroxide or silica sand powder, and the outer periphery of each sphere is coated with an adhesive layer such as an epoxy resin, as shown in an enlarged view in FIG. The spheres 5 are connected to each other by an adhesive layer 6 coated on the outer periphery of the spheres 5.

When stamping with the bar 4 for each layer, the diameter of the bar 4 is as thin as 2 cm and the pressing area is small, so that the sphere 5 escapes and moves in the lateral direction when stamping. , The density of the spheres 5 and 5 is uneven,
Since such density unevenness is dispersed in each layer,
The density of the resin mold as a whole becomes substantially uniform.

That is, as shown in FIG. 3, even if a portion having a high density is formed in a portion indicated by a black portion in the first layer 3a,
In the upper second layer 3b, a portion having a large density is generated at a shifted position, and in the third layer 3c further above, a portion having a higher density is formed at a further shifted portion, so that the overall density is substantially uniform. It becomes something. Accordingly, the pores 7, 7 formed between the spheres 5, 5 formed therein are also substantially uniform, and further, since the spheres 5, 5, 5 are used, the pores 7, 7 are formed in communication between the spheres 5, 5.
