以下、本発明の実施の形態を図面に基づいて説明する。
まず、図１乃至図３を参照する。本発明の樹脂成形充気用ノズル１００は、充気用ノズル２０を含み、充気用ノズル２０は、樹脂成形体１０と一体成形され、充気装置通過ユニット２１と、充気装置通過ユニット２１と一体射出成形される回復ユニット２２と、を含む。樹脂成形体１０は、一面が裏面１１であり、他面が外面１２である。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
First, FIG. 1 to FIG. 3 will be referred to. The resin molding and charging nozzle 100 of the present invention includes a charging nozzle 20, and the charging nozzle 20 is integrally formed with the resin molded body 10, and includes a charging device passing unit 21 and a charging device passing unit 21. And a recovery unit 22 integrally injection-molded. One surface of the resin molded body 10 is a back surface 11, and the other surface is an outer surface 12.

充気装置通過ユニット２１は、樹脂成形体１０の裏面１１に延びるように成形され、中空な構成であり、樹脂成形体１０の外面１２へ開放する充気装置挿入空間２１１を有し、充気装置通過ユニット２１の樹脂成形体１０の裏面１１に延びる一端に切り欠２１２が設けられる。切り欠２１２の延び方向を切り欠方向Ｄ１と定義する。 The charging device passing unit 21 is formed so as to extend on the back surface 11 of the resin molded body 10 and has a hollow configuration, and has a charging device insertion space 211 that opens to the outer surface 12 of the resin molded body 10. A notch 212 is provided at one end extending to the back surface 11 of the resin molded body 10 of the device passing unit 21. The extending direction of the notch 212 is defined as a notch direction D1.

回復ユニット２２は、充気装置通過ユニット２１と一体射出成形され、弾性回復力Ｆを有する。弾性回復力Ｆの回復方向を弾性回復力方向Ｄ２と定義する。弾性回復力方向Ｄ２が切り欠方向Ｄ１と垂直する。回復ユニット２２が切り欠２１２の対向する両側から切り欠２１２へ弾性回復力Ｆを加える。本実施例では、回復ユニット２２は、切り欠２１２が露呈するように充気装置通過ユニット２１の外面を覆う。樹脂成形体１０、充気装置通過ユニット２１及び回復ユニット２２は樹脂射出成形されたものである。回復ユニット２２の弾性回復力は充気装置通過ユニット２１の弾性回復力よりも大きい。本実施例では、回復ユニット２２と充気装置通過ユニット２１とは、相違する樹脂材料で作製される。 The recovery unit 22 is integrally injection-molded with the charging device passage unit 21 and has an elastic recovery force F. The recovery direction of the elastic recovery force F is defined as the elastic recovery force direction D2. The elastic recovery force direction D2 is perpendicular to the notch direction D1. The recovery unit 22 applies an elastic recovery force F to the notch 212 from opposite sides of the notch 212. In the present embodiment, the recovery unit 22 covers the outer surface of the charging device passage unit 21 so that the notch 212 is exposed. The resin molded body 10, the charging device passing unit 21, and the recovery unit 22 are formed by resin injection molding. The elastic recovery force of the recovery unit 22 is larger than the elastic recovery force of the charging device passing unit 21. In this embodiment, the recovery unit 22 and the charging device passage unit 21 are made of different resin materials.

次に、本発明の樹脂成形充気用ノズル１００の使用方法を説明する。まず、樹脂成形体１０の外面１２から充気装置の充気ヘッドＡを充気装置通過ユニット２１の充気装置挿入空間２１１に挿入して、更に、充気装置通過ユニット２１の切り欠２１２を通過すると、図４に示すように、充気装置の充気ヘッドＡが切り欠２１２を通過して樹脂成形体１０を貫通して、充気作業を施すことができる。このとき、充気ヘッドＡが充気装置通過ユニット２１の切り欠２１２を突っ張るため、充気装置通過ユニット２１により充気装置通過ユニット２１の上で成形される回復ユニット２２が外側へ広げる力を受け、なお、回復ユニット２２の弾性回復力Ｆが切り欠２１２の両側から中央へ切り欠２１２に加えるため、充気の過程中には、切り欠２１２が充気ヘッドＡに緊密に合せ、気体が外部に漏れ出すことはない。 Next, the usage method of the nozzle 100 for resin molding filling of this invention is demonstrated. First, the charging head A of the charging device is inserted into the charging device insertion space 211 of the charging device passing unit 21 from the outer surface 12 of the resin molded body 10, and the notch 212 of the charging device passing unit 21 is further inserted. When passing, as shown in FIG. 4, the charging head A of the charging device can pass through the notch 212 and penetrate the resin molded body 10 to perform the charging operation. At this time, since the charging head A stretches the notch 212 of the charging device passage unit 21, the recovery unit 22 formed on the charging device passage unit 21 by the charging device passage unit 21 has a force to spread outward. In addition, since the elastic recovery force F of the recovery unit 22 is applied to the notch 212 from both sides of the notch 212 to the center, the notch 212 closely aligns with the charging head A during the charging process. Will not leak out.

充気作業が終了して、切り欠２１２から充気ヘッドＡをゆっくり抜き出すときには、回復ユニット２２の弾性回復力Ｆが切り欠２１２の両側から中央へ切り欠２１２に続けて加えるため、切り欠２１２が迅速に気密になる。図５に示すように、切り欠２１２から充気ヘッドＡを完全に抜き出すときには、回復ユニット２２により切り欠２１２が気密状態になり、気体が切り欠２１２から外部に漏れ出すことはない。 When the charging operation is finished and the charging head A is slowly extracted from the notch 212, the elastic recovery force F of the recovery unit 22 is applied continuously from both sides of the notch 212 to the notch 212. Quickly become airtight. As shown in FIG. 5, when the charging head A is completely extracted from the notch 212, the notch 212 becomes airtight by the recovery unit 22, and gas does not leak out from the notch 212.

本発明の樹脂成形充気用ノズル１００は、樹脂射出成形により一体成形されるため、作製の工程が極めて簡単であり、樹脂成形体１０、充気装置通過ユニット２１と回復ユニット２２の間に隙間がなく、その構造に気体が漏れ出す欠陥がない。 Since the resin molding and charging nozzle 100 of the present invention is integrally molded by resin injection molding, the manufacturing process is extremely simple, and there is a gap between the resin molded body 10, the charging device passing unit 21 and the recovery unit 22. There is no defect that gas leaks in the structure.

もちろん、本発明の樹脂成形充気用ノズル１００の回復ユニット２２を設置する位置は上記に限定されない。図６に示すように、回復ユニット２２は、切り欠２１２が露呈するように充気装置通過ユニット２１の両側を覆ってもいいし、図７に示すように、回復ユニット２２は充気装置通過ユニット２１の上端の両側に傾斜に設けられてもいいし、図８に示すように、回復ユニット２２は充気装置通過ユニット２１の周面の両側に設けられてもいいし、図９に示すように、回復ユニット２２は充気装置通過ユニット２１の上端の両側に設けられてもいいし、図１０Ａ及び図１０Ｂに示すように、回復ユニット２２は充気装置通過ユニット２１の切り欠２１２の両側を貫通してもよい。具体的には、上記の実施例の回復ユニット２２は、充気装置通過ユニット２１と一体成形され、切り欠２１２の両側に分布するため、回復ユニット２２の弾性回復力Ｆが切り欠２１２の両側から中央へ切り欠２１２に加えることができ、何時でも気体が切り欠２１２から外部に漏れ出すことはない。 Of course, the position where the recovery unit 22 of the resin molding and filling nozzle 100 of the present invention is installed is not limited to the above. As shown in FIG. 6, the recovery unit 22 may cover both sides of the charging device passing unit 21 so that the notch 212 is exposed, and the recovery unit 22 passes through the charging device as shown in FIG. The recovery unit 22 may be provided on both sides of the peripheral surface of the charging device passing unit 21 as shown in FIG. 8, as shown in FIG. Thus, the recovery unit 22 may be provided on both sides of the upper end of the charging device passage unit 21, and the recovery unit 22 may be provided on the notch 212 of the charging device passage unit 21 as shown in FIGS. 10A and 10B. You may penetrate both sides. Specifically, since the recovery unit 22 of the above embodiment is integrally formed with the charging device passing unit 21 and distributed on both sides of the notch 212, the elastic recovery force F of the recovery unit 22 is on both sides of the notch 212. Can be added to the notch 212 from the center to the center, and no gas leaks out of the notch 212 at any time.
