【発明の詳細な説明】
この発明は、医療用パイプのジヨイント、又は注射器の
ジヨイント等に使用する合成樹脂筒状体の成形方法に関
するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for molding a synthetic resin cylindrical body used for a joint of a medical pipe, a joint of a syringe, or the like.
従来から、腔、管、血管などに挿入して液体の注射また
は吸入、さらに通路の罠μ確保などを目的として使用さ
れるカテーテルのアダプタは種々知られており、これら
アダプタは柔軟で弾力性を有する合成樹脂の筒状体とし
て、特に射出成形を用いて作製されている。Various types of adapters have been known for catheters that are inserted into cavities, tubes, blood vessels, etc. for the purposes of injecting or inhaling liquids, as well as securing passageways.These adapters are flexible and elastic. The cylindrical body made of synthetic resin is manufactured using injection molding.
しかしながら、射出成形を用いた場合、従来のアダプタ

アダプタは、曲げられたり、圧力が加えられたりした場
合にも液体の流れが阻止されない様に、アダプタ本体の
内腔の形状にばかり改良工夫がなされており、その外表
面の形状には何の考慮もされていなかったからである。However, when injection molding is used, the shape of the conventional adapter makes it difficult to pull out the mold. This is because in conventional adapters, the shape of the inner cavity of the adapter body has been improved so that the flow of liquid is not blocked even when it is bent or pressure is applied, and the shape of the outer surface of the adapter body has been improved. This is because no consideration was given to
そこで、この発明の目的とするところは、アダプタ本体

体の内腔が完全に塞がれることなく、液体の流れが阻止
されない様にしたカテーテルのアダプタとしての合成樹
脂筒状体の成形方法を提供することにある。Therefore, the purpose of this invention is to improve the shape of the outer surface of the adapter body to make it easier to pull out the mold, and to prevent bending or pressure from being applied due to the shape of the outer surface. To provide a method for molding a synthetic resin cylindrical body as an adapter for a catheter, in which the lumen of the adapter body is not completely blocked and the flow of liquid is not obstructed even when the adapter body is heated.
以下、この発明の合成樹脂筒状4の成形方法を実施例と
して示した図面に従って説明する。EMBODIMENT OF THE INVENTION Hereinafter, the method for molding the synthetic resin cylindrical shape 4 of the present invention will be explained with reference to the drawings shown as examples.

。(第1図に示す。)
次に、下型(3)を矢印の方向へ移動させると同時にス
ライドコア(5)(6)も矢印の方向へずらしていく。The molten synthetic resin raw material is forced into the mold of the synthetic resin cylindrical body (9) constructed as described above, and is cooled and solidified. (See FIG. 1.) Next, the lower die (3) is moved in the direction of the arrow, and at the same time the slide cores (5) and (6) are also shifted in the direction of the arrow.
(第2図に示す。)

ア(5)(6)の入子(7)(8)が引き抜かれる。(As shown in Figure 2.) Furthermore, the lower die (3) is moved in the direction of the arrow until the slide cores (5) and (6) are separated from the upper die (1), and the slide cores (5) and (6) are moved in the direction of the arrow. ) is also its nest (7) (8)
is shifted in the direction of the arrow until it separates from the synthetic resin cylindrical body (9). (As shown in Fig. 3.) Since the synthetic resin cylindrical body (9) of the present invention is molded as described above, in the state shown in Fig. 2, the synthetic resin cylindrical body (9) is attached to the slide core. (5) Nested in (6) (7) (
8), the insert (2) of the upper mold (1) is pulled out, and further, in the state shown in Fig. 3, the synthetic resin cylindrical body (9)
) are two annular grooves (10) formed in the insert (4) of the lower mold.
), and the inserts (7) and (8) of the slide cores (5) and (6) are pulled out.
したがって、合成樹脂筒状体(9)は上型(1)の入子
