Description of the Related Art As a method of manufacturing an outer blade of an electric razor, which is made of a thin metal plate and has a large number of beard-introducing blade holes, a resist is formed on the surface of a mother die made of aluminum or the like and primary plating is added. There is an electroforming method in which an outer blade is formed by performing electroforming after performing. Since the outer blade formed by this electroforming method cannot be curved after being manufactured, when forming an outer blade having a substantially inverted U-shaped cross section, the mother having a substantially inverted U-shaped cross section is used. It is manufactured by performing electroforming on the mold surface.

っている。However, when electroforming is performed using a master die having the above-described cross-sectional shape, the distance between the skirt and the electrode becomes longer than the distance between the top and the electrode. As a result, the thickness of the hem of the finished outer blade is smaller than that of the top, and the problem is that the strength of the hem of the outer blade used for attachment to the outer blade frame decreases. Has become.

What is formed by the casting method is characterized in that it has a notch in the hem or has many holes in the hem.

The illustrated outer blade 1 not only has a letter shape, but also has a curved shape in the longitudinal direction. The outer blade 1 has a large number of beard-introducing blade holes 2 at the top thereof, and a hem in the lateral direction. The portion has a mounting hole 3 for mounting on an outer blade frame (not shown). In addition, a plurality of notches 4 and a large number of holes 5 are provided at the hem.
It has and.

示したが、一方だけであってもよい。The outer cutter 1 is formed by electroforming on the surface of the mother die having a shape matching the shape of the outer cutter 1 shown in FIG. The cutouts 4 and a large number of small holes 5 provided in the portion (to be exact, the portions for forming the cutouts 4 and the holes 5 on the surface of the mother die) have a small hem area, and therefore are formed by electroforming. The current density at the time increases, and for this reason, the blade thickness of the skirt can be made substantially the same as that of the top. In this embodiment, the notch 4 and the multiple holes 5 are provided, but only one may be provided.

ある。In the embodiment shown in FIG. 3, the mounting hole 3 is formed as a stepped hole in addition to the notch 4 and the large number of holes 5, that is, as shown in FIG. It is shown that the forming portion 63 of the mounting hole 3 in FIG. 2 is stepped so that the peripheral portion of the mounting hole 3 is thickened. In the figure, 61 is a resist, and 62 is primary plating.

のである。As described above, in the present invention, since the area of the skirt is reduced by the notches and the large number of holes,
A sufficient current density can be secured during electroforming, and the blade thickness does not decrease.For this reason, the hem can be made to have sufficient strength, and the hem is used. The attachment strength of the outer blade to the outer blade frame does not pose a problem.
