After that, the sanitary ware body is molded by demolding, and the resin mold needs to have good communicating pores inside in order to uniformly eject water and air at the time of demolding. Conventionally, the mold is formed by casting resin into the case mold to form a predetermined shape.In the conventional method of manufacturing a resin mold by pouring, the porosity formed in the resin mold is poor and the internal density is low. Also, the thickness was likely to be non-uniform.

It can be stacked in multiple layers to make the overall density uniform and the pores formed inside can be uniform, and it does not require a large pressurizing device such as a press, and it can be connected by a simple device. It is possible to manufacture a resin mold for pressure casting in which the pores of the above are substantially uniform.

る。At the time of this manufacturing, first, the filler 3 to be the first layer 3a is filled on the upper surface of the case mold 1, and a rod 4 having a diameter of about 2 cm is used to move the rod 4 up and down. 1 layer 3a
Stamp and harden. Then the second layer 3b on top
And then the second layer 3b is stamped with the rod 4. After that, the third layer 3c is filled in the upper portion, and the third layer 3c is also stamped by the rod 4.
In this way, each layer is stacked in layers while stamping with the bar material 4, and sequentially stacked from the first layer to the second, third, fourth, fifth and sixth layers to manufacture a resin mold of a predetermined shape. To do.

る。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 epoxy resin, as shown in an enlarged view in FIG. The spheres 5 and 5 are connected by the adhesive layer 6 coated on the outer periphery of the sphere 5.
【0008】尚、各層毎に棒材4でスタンピングする際

このような密度のムラは各層において分散するために、
造形される樹脂型全体としての密度はほぼ均一なものと
なる。When stamping each layer with the rod 4, the diameter of the rod 4 is as thin as 2 cm, and the pressing area is small, so that the sphere 5 escapes laterally when stamping, and each layer is moved. In, the density of spheres 5 and 5 is uneven,
Since such unevenness in density is dispersed in each layer,
The density of the entire resin mold to be molded becomes substantially uniform.

る。That is, as shown in FIG. 3, in the first layer 3a, even if a portion having a high density is formed at a portion indicated by a black-painted portion,
In the upper second layer 3b, a large density portion is generated in a displaced position, and in the upper third layer 3c, a large density portion is generated in a further displaced position, so that the overall density is substantially uniform. It becomes a thing. Therefore, the pores 7 and 7 formed inside the spheres 5 and 5 are substantially uniform, and since the spheres 5 and 5 are used, the pores 7 and 7 are formed in a communicating manner between the spheres 5 and 5. To be done. In this example, 50
Spheres 5 and 5 were used at a mixing ratio of%, but the mixing ratio of spheres was 3
If it is 0% or more, the pores can be satisfactorily made uniform.
