印へ方向へ。(Conventional Example) Conventionally, when a bevel gear and at least one other gear are integrally molded from plastic, their shape is as shown in FIG. It is composed of a bevel gear part 1, a connecting part 2, and a spur gear part 3. The mold used for molding consists of four blocks, and the block for molding the bevel gear part 1 is in the direction of the arrow.
平歯車部３を成形するブロックは矢印Ｂ方向へ。Move the block forming the spur gear part 3 in the direction of arrow B.

方向に移動する。(Embodiment) FIG. 2 shows an embodiment of the present invention, in which a bevel gear part 1 and a connecting part 4 are shown.
and a spur gear part 3, but the difference from the conventional example shown in FIG. 1 is the shape of the connecting part 4. The shape of the connecting portion 4 is such that the bevel gear portion 1 increases radially from the minimum diameter portion to the maximum diameter portion, and continues to expand radially from the maximum diameter portion. Considering the type,
The type consists of two blocks. One block is a block for molding the bevel gear portion 1 and the connecting portion 4, and after molding, moves in the direction of arrow A relative to the molded product. In addition, the other block is a block for molding the spur gear part 3, and after molding, it is shown as arrow B relative to the molded product.
move in the direction.
本発明は、上述従来例のように、４つのブロックからな
る成形型を２つのブロックからなる成形型に変更する手
段を提供するものである。The present invention provides means for changing a mold consisting of four blocks into a mold consisting of two blocks, as in the conventional example described above.
本発明はプラスチック成形歯車のみならず、鋳物による
金属製歯車にも適用し得る。The present invention can be applied not only to plastic molded gears but also to cast metal gears.
（効 果）

になるため成形品のコストも安価となる。(Effects) As described above, by changing the shape of the molded product from the conventional example shown in Figure 1 to the embodiment of the present invention shown in Figure 2, the number of blocks in the mold can be reduced from four to two. . In other words, the mold structure can be made cylindrical, and the mold manufacturing cost is therefore low, so the cost of the molded product is also low.
