On the other hand, the present invention relates to a method for converging and fixing piping so that the piping can be installed in a concentrated manner for convenient installation or for maintaining constant spacing.

同時に行なわせる方法も広く行なわれていた。(Prior art) Conventionally, many of these types of piping have used small-diameter metal pipes with an outer diameter of about 20(1) or less; As a method of focusing and fixing, set multiple small diameter metal tubes in parallel on a jig and braze adjacent metal tubes directly to each other, or use metal fittings for appropriate installation and braze them to this. This was done by inserting multiple metal tubes in parallel into a mold with an appropriately shaped cavity, and then injecting molten resin into the mold and installing it. A method of forming the piece and fixing the metal tube at the same time was also widely used.

れていないのが実状である。(Problem to be Solved by the Invention) However, in recent years, due to the demand for weight reduction, there has been an increasing trend to adopt small-diameter resin tubes made of synthetic resin such as nylon, and the above-mentioned method for focusing and fixing small-diameter tubes has been gaining momentum. Although some results have been obtained when the piping is made of metal pipes, the former method cannot be used at all when the piping is made of piping or resin tubes, and the latter method cannot be used at all. In the case of injection molding, the installation of brackets, sub-elements, etc. is done by molding a piece and using this method.
The resin tube of
4-,,,'L) Even in the case of a piece of meat, the resin tube with the gold placed inside is softened and deformed by the heat and injection pressure of the molten resin injected at the time of making the body/I part. As the injected resin solidifies, the pipe line of the resin tube fixed in place may become soaked, or even if it does not collapse, the pipe line will be significantly deformed and the specified pore diameter cannot be maintained, resulting in an unsatisfactory result. The reality is that no results have been obtained.

They are placed in a mold so that they are all sandwiched in the width direction of the array, and the metal is melted inside and/or the thermoplastic resin is injected and then solidified, allowing the installation to be done in one piece. This is a method for focusing and fixing small diameter resin tubes, and at the same time, small diameter resin tubes L-
When fixing the pipe, the basic principle is to removably insert a metal core bar into the resin pipe before pushing it into the mold.

Figure 1 shows the injection of hot well plastic resin in a mold according to the method of focusing and fixing a small diameter resin tube according to the present invention. FIG. 1 is a cross-sectional view showing the state of 3411-diameter resin tubes 7 and 1 (herein, 1 is a small diameter resin tube 7, which forms different flow paths for citron, gas, etc.).
In advance, as shown in Figure 2 □ and h in L-Goo,
A metal rod 2 having an outer diameter slightly smaller than the inner diameter or a core metal 2 made of a C'' metal tube is removably inserted.

A suitable form of attachment is one made of gold with a cavity 4 formed therein, such as injection molded. The mold 3.3 is provided with an injection port 15 and a cooling water channel 6 for injecting molten thermoplastic resin into the cavity 4. The thermoplastic resin 7 is formed so as to be quickly cooled and solidified within the cavity H.

くことか肝要である。A metal rod or tube made of stainless steel or copper is used for the core bar 2, and in either case, it has an outer diameter slightly smaller than the inner diameter of the small diameter resin tube 7, and the jI east fixation is completed. It is important to make the outer peripheral surface smooth and removable by applying a mold release agent so that it can be easily removed from the resin tube later.

。In addition, if a metal tube is used as a core metal, connect piping for refrigerant flow to both ends of the metal tube, and add water, air, or brine inside the tube during injection molding of the molten resin (inside the mold). Using soil to forcefully circulate the refrigerant is actually extremely effective in preventing softening and deformation of the resin tube (IF), and it also shortens the molding cycle tie 11 and improves productivity. It is extremely important to have 1L.

通して固定する。A plurality of small diameter resin tubes 1 into which core metals 2 have been inserted in this way are arranged parallel to each other in a planar or three-dimensional form at a desired interval, and if necessary, the arrangement is done using an appropriate jig or the like. It is temporarily fixed so as to keep it in that state, and then the desired part is inserted into the mold 3.3'' in the width direction so as to be collectively clamped and fixed.

する。Next, the heated and melted thermoplastic resin is injected from the injection jet 115 into the cavity 11 formed in the mold 3.3゛ to fill the cavity 11.
When the thermoplastic resin in the mold is cooled and solidified by filling it with cooling water and supplying cooling water to the flow path 6, the thermoplastic resin 7 is formed around the small diameter resin chips 7 and -bu 1-. It melts and solidifies. After cooling is completed, the 9/1-shaped product integrated with the side-diameter resin tube 1 is taken out from the mold 3.3'', and the core bar 2 is pulled out from the small-diameter resin tube to complete the work.

ブの取付は片ノ＼の固定を確実に行なっことか出来る。Since the method of focusing and fixing the small-diameter resin tubes 7 of the present invention is carried out by the method described above, the thermoplastic resin molten at high temperature is placed in a mold in which the small-diameter resin tubes and -L-tubes are held in parallel. In the case of injection, since the axial diameter resin tube has a metal core inserted into it, the injection pressure may cause it to soak and block the pipeline, or deform and change the diameter of the pipeline. At the same time as the molding of the pieces, the parallel resin chips 1-
You can install the bracket by making sure to securely fix one end.

である。In particular, when a metal tube is used for the core metal and a refrigerant such as water or brine is passed through it during injection of thermoplastic resin, cooling of the injected resin is faster than when cooling only with a mold. Since this is carried out quickly, deformation due to softening of the small diameter resin tube is completely prevented, and the cooling effect increases productivity, making it extremely effective.
