b. Conventional technology Conventionally, a preform is formed in advance by using, for example, ceramic whiskers or short fibers, the preform is set in a mold, and then a molten metal that serves as a matrix is poured into the preform to forge the molten metal. In order to strengthen the metal part, the composite part composed of the preform and the metal part is formed.

c. Problem to be Solved by the Invention FIG. 3 shows an example in which the piston top is compound-reinforced by the above-mentioned conventional method, and the piston 1 has a composite-reinforced part 2 formed on the top thereof. In manufacturing such a piston 1, a crescent-shaped preform 3 is formed from a composite material (such as whiskers of ceramics or short fibers) and then set on the bottom of a mold 4 as shown in FIG. . A spherical concave portion 5 is formed on the bottom of the mold 4 so as to match the spherical surface of the preform 3, and a horizontal portion 6 is provided around the spherical concave portion 5.

Now, when trying to set the preform 3 in the spherical concave portion 5 in the mold 4, both the spherical concave portion 5 and the contact surface of the preform 3 in contact with the spherical concave portion 5 are spherical, so that the preform 3 can be set at an accurate position. I can't do it easily. Moreover, the confirmation is not easy. After setting at a more accurate position, pour the molten alloy from the upper part of the mold 4 and pressurize it with the upper mold 7,
If the preform 3 is displaced as shown by the chain line in FIG. 4 and the reinforcing portion is biased, the piston will be manufactured. Therefore, there is a problem that a stable product with constant quality cannot be obtained. That is, no particularly effective measure has been taken for a method of accurately setting such a preform that is easily displaced and preventing the preform from being easily displaced even after being set. Preform 3
As such, it has a drawback that the sharp peripheral edge is easily chipped.

d. Means for Solving the Problem In accordance with the above purpose, the present invention sets a crescent-shaped preform having the same spherical portion as the spherical concave portion in the spherical concave portion of the inner bottom of the molding die, and pours the molten metal into the preform. In the case of molding a composite reinforced product consisting of spherical end faces with a horizontal portion provided around the spherical concave portion of the inner bottom of the molding die, a flange that abuts this is provided around the spherical portion of the preform. Preform structure characterized by By solving the above, the above problems have been solved.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The structure of the preform according to the present invention, which is suitable for the mold 4 as it is, will be described.

In FIG. 1, reference numeral 20 is a preform according to the present invention, which is formed by using an appropriate composite material. The preform 20
Is provided with a spherical surface portion 21 corresponding to the spherical concave portion 5 of the mold 4, and a flat portion, that is, a horizontal annular flange 22 is provided around the outer periphery of the spherical surface portion 21.

The flange 22 is formed so as to be able to contact the horizontal portion 6 provided around the spherical recess 5 of the mold 4. That is, the surface continuous from the surface of the flange 22 of the preform 20 to the spherical surface portion 21 thereof extends from the horizontal portion 6 of the mold 4 to the spherical concave portion 5.
It is formed to match the surface of the.

In order to set the preform 20 in the mold 4, the spherical part 21 of the preform 20 is inserted from the upper part of the mold 4 so that the flange 22 and the spherical part 21 are both metal. It easily matches the corresponding surface of the mold 4 and is easily set in the correct position.

In such a state, when the molten alloy is poured into the mold 4 and pressurized by the upper mold 7, it tries to move the preform 20 left and right or front and back like the case of the conventional example. The force acts because the lower surface of the peripheral flange 22 is in contact with the horizontal portion 6 of the mold 4 over the entire circumference, so that the preform 20 is not displaced upward as in the conventional example. Does not happen.

なお前記平坦なフランジ部分はプリフォームの全周に

The flat flange portion may not be provided all around the preform, but may be partially provided.

In the manufactured piston, since the flange 22 is provided, unnecessary portions of the corners may be cut off as appropriate.
