ーを取付けて塞ぎスライドスイツチを得ていた。In general, this type of electronic component, for example, a method of manufacturing a slide switch, forms a terminal on a hoop-shaped material, conveys the terminal, molds a wafer on the terminal, and then sends the terminal to an automatic assembling machine. The wafer is separated from the hoop-shaped material by cutting from the hoop-shaped material, a slider, which is a loading component, is loaded into the wafer provided with the separated terminals, and the slider is positioned and fixed with respect to the wafer with a jig and transported. A cover was attached to the opening of the wafer loaded with, and a slide switch was obtained.

材2,2を所定ピツチで搬送するものである。In these figures, reference numeral 1 denotes a molding machine, which is not particularly shown, has an upper mold and a lower mold, and a cavity is provided on a joint surface between the upper mold and the lower mold. The molten resin is injected into the inside and solidified. Two hoop-shaped members 2, 2 are interposed between the upper die and the lower die, and are conveyed in the direction of the arrow. The terminals 4 formed on the hoop-shaped members 2, 2 are arranged in the cavity. Accordingly, the molding 5 is performed on the terminal by the injection and solidification of the molten resin. Reference numeral 3 denotes a feeder for the hoop-shaped members, which conveys the hoop-shaped members 2, 2 at a predetermined pitch.
ところで、この種の射出成形装置では、溶融した樹脂
を固化させる工程があるので、冷却時間を要し、その成
形サイクルの短縮に限界があつた。By the way, in this type of injection molding apparatus, since there is a step of solidifying the molten resin, a cooling time is required, and the shortening of the molding cycle is limited.
特に、上流側に配置される打抜き加工成形機の能力に
比べると、射出成形機の能力はかなり低いものであり、

条あるいは多条にして射出成形機に流していた。In particular, the capacity of the injection molding machine is considerably lower than the capacity of the punching molding machine arranged on the upstream side,
In order to adjust the difference, conventionally, the ability of the punching molding machine was reduced to match the capacity of the injection molding machine, or the hoop-shaped material processed by the punching molding machine was rolled up, Then, as shown in FIG.
It was run into the injection molding machine in multiple or multiple sections.

つた。Therefore, the loss of ability naturally became a barrier to mass production. Therefore, when a multi-cavity mold is used, the dimension A is limited due to mold manufacturing accuracy, molding machine specifications, and the like, which is not sufficient. In addition, in the case of single winding, there is a possibility that the quality may be deteriorated by bending the hoop-shaped material, and the winding may not be possible. In addition, if it is possible to use a multi-section for an injection molding machine when the specification can be made by winding, it is also necessary to make the downstream assembly process compatible with multiple sections. It was uneconomical.
