必要となりやすい欠点を有し°Ｃいた。Conventionally, when manufacturing resin molded coils, an electromagnetic coil is placed inside the mold, and the resin is injected and hardened to obtain the resin molded coil. While sushi can be easily molded using a split mold or a mold with a slope, a split mold with slopes or subdivisions on two sides is used for the inner mold. However, it is difficult to remove the inner mold because the shrinkage of the cured resin causes it to stick tightly to the inner mold, and if you try to remove C by applying pressure to the mold, the mold coil will crack. It has the disadvantage that it tends to cause the occurrence of heat and requires a mold release device that involves a dog.
本発明はこの様力欠点をなくし、安価で取り扱いが簡単
な内型構造を提供するものである。The present invention eliminates this disadvantage and provides an internal mold structure that is inexpensive and easy to handle.
以下、本発明を図を参照して説明する。Hereinafter, the present invention will be explained with reference to the drawings.

法規制面に勾配を付ける事なく型はすしが簡単である。FIG. 1 is an exploded perspective view of the inner mold according to the present invention, in which a square cylindrical plate full-container mold 1 is arranged in the center, and the inner side is placed along each of the four sides of the square cylindrical plate full-container mold 1 instead. To regulate the inner dimensions of the molded coil, pressurized polymer material plates 2 are arranged so that when the outer surface is combined, it will have an electrocardiographic shape (for example, the inner mold shape is the prototype). (If so, make it an arc surface)
. FIG. 2 shows a state in which the square cylindrical full-container mold 1 and the polymeric material plate 2 are combined to form an inner mold. The polymer material plate 2 has a larger coefficient of thermal expansion than the mold resin, and the difference is in the range of 10 x 10 to 60 x 10-6/C. If the difference in coefficient of thermal expansion is too small, a large amount of pressure will be required to remove the mold, just like with conventional molds, which will easily damage the coil, while if the difference in coefficient of thermal expansion is too large, the internal dimensions will need to be highly accurate. Errors are likely to occur in some cases. However,
When using a polymeric material plate 2 having the above-described range of thermal expansion coefficient difference, when the resin is heated and hardened and cooled when removed from the mold, the polymeric material plate 2 will shrink more than the mold resin, and the inner dimension regulating surface will shrink. The mold makes it easy to make sushi without adding any slope.
そして、四角筒板全容器状型１との合わせ面に勾配を付
けると型はすしの効果は一段と太きい。If the mating surface of the rectangular cylindrical plate and the full container-shaped mold 1 is sloped, the effect of the sushi mold will be even greater.
