130〜150％、好ましくは110〜120％程度の樹脂を
ウエブに含有させるのが適当である。 Excess resin refers to the amount of resin that can be contained in the web after compression (the difference between the apparent volume of the web and the actual volume of the fibers and thin wires that make up the web, that is, the resin whose volume is equal to the volume of the voids in the web). (hereinafter referred to as the theoretical resin amount).
It is appropriate for the web to contain about 130 to 150%, preferably 110 to 120%, of the resin.

るのが適当である。 A compressible web containing an excess liquid curable resin is pressed and compressed between the first mold 1 and the second mold 4.
As shown in FIG. 1, a resin-containing web 12 is placed on the first mold 1, and the second mold 4 is lowered,
As the gap between the first mold 1 and the second mold 4 becomes smaller, the web is compressed, the porosity of the web becomes smaller, and the amount of resin that the web can contain gradually decreases.
Excess resin is discharged to the outside of the second mold 4 from the discharge hole 5, and air bubbles that should be contained in the resin are also discharged and removed at the same time. At this time, in order to prevent the resin from flowing out between the first mold and the second mold, a mold release agent (not shown) is applied to the inner surface of the first mold 1 so as to be in close contact with the circumferential surface 6 of the first mold 1. It is appropriate to provide a fence 7 with a given shape.

接着することができる。 Furthermore, the first mold 1 and the fence 7 can be made slightly larger than the second mold 4, and a gap 8 of about 5 to 8 mm can be formed between the fence 7 and the second mold 4. Excess resin is also discharged from this cavity 8, and the cavity 8 is filled with resin. As will be described later, when the resin is cured, the resin also covers the circumferential surface 9 of the second mold 4 and hardens, so that the resin can be bonded to the second mold 4 even more firmly.
次いで必要に応じ、第２の型４の外部に排出さ
れた過剰の樹脂を除去した後、要すれば加熱して
樹脂を硬化させる。 Next, if necessary, after removing the excess resin discharged to the outside of the second mold 4, the resin is cured by heating, if necessary.

できる。 The web 12 whose voids are filled with resin is brought into close contact with the surfaces of the first mold 1 and the second mold 4 by the above-mentioned compression process, and is slightly inserted into the discharge hole 5 provided in the second mold 4. Since the resin enters and cures while completely filling the discharge hole 5, the cured resin 10 reinforced with the web 12 is firmly adhered to the surface of the second mold 4 and becomes integral with the second mold 4. By combining the first mold 1 and the fence 7, a resin molding mold 11 of the present invention as shown in FIG. 3 can be obtained.

1' are used in pairs. (The manufacturing method for mold 11' is exactly the same as that described above, so it will be omitted.) (Function of the invention) The compressible web is molded into a second mold having a resin discharge hole with the cavity filled with liquid thermosetting resin. The resin was compressed while being pressed against the surface of the first mold to which a mold release agent was added, and during this time, excess resin was discharged from the discharge hole along with the air bubbles present in the resin, and the resin was uniformly reinforced with the web. In this state, it is brought into close contact with the first mold and the second mold. The resin and web enter the discharge hole and are firmly and integrally connected to the second mold.

The mold is a wooden mold with low mechanical strength and is durable enough to withstand use, and is easy to manufacture and finish. Since a mold release agent is applied to the surface of the first mold, it is easy to release the mold from the cured resin, and a resin molding mold having a smooth surface can be obtained.
