【発明の詳細な説明】
第１図は本発明の実施例における流路部材の流路を示す
断面図である。DETAILED DESCRIPTION OF THE INVENTION FIG. 1 is a sectional view showing a flow path of a flow path member in an embodiment of the present invention.
まずアクリル酸樹脂の粉末状や粒状の原材料と、流路形
状に形成した例えばＬ字形またはＵ字形の銅パイプの金
属バイブロとを、圧縮成型機の７０℃程度に予備加熱し
た金型４内に配置する。First, powdered or granular raw materials of acrylic acid resin and a metal vibro, such as an L-shaped or U-shaped copper pipe formed into a channel shape, are placed in a mold 4 of a compression molding machine preheated to about 70°C. Deploy.
この時流路出入口の位置決めを行なうため、金属パイプ
３の端部を金型４内に配置したガイド板５のガイド穴６
で保持する。At this time, in order to position the entrance and exit of the flow path, the end of the metal pipe 3 is placed in the guide hole 6 of the guide plate 5 placed inside the mold 4.
hold it.
次に１６０℃まで昇温し、３ｏｏ／ｄｉの圧力な加えた
状態で１５分程度保持し成型する。その後室温程度まで
冷却して金型４から取り出す。Next, the temperature is raised to 160° C., and a pressure of 3 oo/di is maintained for about 15 minutes to mold. Thereafter, it is cooled to about room temperature and taken out from the mold 4.
次に金属バイブロを３０’Ｃ程度の塩化第二鉄（ＦｅＣ

13) is removed by dissolving in the aqueous solution to obtain a channel member 1 having a channel. The large inner surface of the flow path is machined to follow the surface roughness of the outer circumference of the metal pipe B.
流路出入口の位置決めは、ガイド板にて金属パイプを保
持して行なう例で説明したが、金型に穴を明は金型にて
金属パイプを保持しても良い。この場合必要があれば金
型を分割型にする。The positioning of the inlet and outlet of the flow path has been described using an example in which the metal pipe is held by a guide plate, but the metal pipe may be held by the mold if a hole is formed in the mold. In this case, if necessary, the mold is made into a split mold.
また単純なＵ字形、Ｌ字形の流路で説明したが、金属パ
イプを組合せることにより複雑な形状の流路も得ること

プの曲げ半径を変えて形成すれば調整可能である。金属
パイプを使用したのは、エツチング液がパイプ内径部を
通り金属パイプを完全に除去するためと、溶解除去時間
の短縮を図るためである。Furthermore, although the explanation has been made using simple U-shaped and L-shaped channels, complex-shaped channels can also be obtained by combining metal pipes. Furthermore, the roundness of a portion of the corner of the flow path can be adjusted by changing the bending radius of the metal pipe. The metal pipe was used because the etching solution passes through the inner diameter of the pipe to completely remove the metal pipe, and to shorten the time required for dissolution and removal.
ガイド板のガイド穴に耐熱性でしかもバネ性を有するコ
イルバネ、シリコンゴム等を入れて成型するときの金属
パイプの変形を軽減することもできる。It is also possible to reduce deformation of the metal pipe during molding by inserting a heat-resistant and springy coil spring, silicone rubber, or the like into the guide hole of the guide plate.
以上アクリル酸樹脂を用（・た圧縮成型法で説明したが
、耐薬品性透明樹脂であればアクリル酸樹脂以外の合成
樹脂にも応用可能で、さらに注型法、射出成型法等にも
応用可能である。The above explanation was based on the compression molding method using acrylic acid resin, but it can also be applied to synthetic resins other than acrylic resin as long as it is a chemical-resistant transparent resin, and can also be applied to casting methods, injection molding methods, etc. It is possible.
耐薬品性透明樹脂からなる流路部材の加工を本発明で行

。By processing a channel member made of a chemical-resistant transparent resin using the present invention, a channel with good surface roughness and rounded corners can be obtained, and there is no fluid resistance and no vortex flow at some corners. A channel member having a normal fluid flow without any occurrence can be obtained.

第２図FIG. 1 is a cross-sectional view showing the state after molding after embedding a metal pipe in a flow channel member in a mold for explaining the present invention in detail, and FIG. 2 is a cross-sectional view of the flow channel member for explaining a conventional example. It is a sectional view in a flow path. Figure 2
