The present invention relates to a method for arranging and fixing resin tubes having a relatively small diameter of about 15 m/11 or less.

て配列固定するものであった。(Prior Art) Conventionally, this type of assembly arrangement fixing method generally consists of a separate resin clamp body molded with clamping claw walls for each of a plurality of resin tubes on the surface, or a pair of resin clamp bodies. By using a resin clamp body etc. separately molded with a mating shape, the straight pipe portion on each resin tube side is press-fitted and fixed between each claw wall portion of the clamp body. They were arranged and fixed by being inserted into a pair of semicircular grooves provided between opposing surfaces and fixed by mutual hooking means.

題を有することとなった。(Problem to be Solved by the Invention) However, in this conventional fixing method, since the clamp body is separately molded in advance, the clamping wall portion or the groove portion I\ is fixed. Assembling resin tubes not only makes the work extremely troublesome and reduces work efficiency, but also leaves the clamping wall portions intact, resulting in defects in the claw walls or mutual attachment means, or long-term damage to the claw walls. Due to aging, fatigue, or vibrations from engines, machines, equipment, etc., the resin tube often becomes partially detached, making the fixing unstable. However, due to variations in the degree of clamping, the resin tube is crushed and deformed, resulting in problems such as inhibiting the flow of internal fluid.

The object of the present invention is to propose a method for fixing resin tubes in a collective arrangement, which can securely fix the resin tubes at the fixing portions 2 and eliminate immersion and deformation of the resin tubes at the fixing portions.

形をなくすこととなる。(Means for Solving the Problem) In order to achieve the above-mentioned object 1, the present invention has a plurality of resin tubes arranged substantially parallel to each other with intervals maintained, and the straight pipe portions of each other are arranged at appropriate positions in the opposing interiors. A mold consisting of a pair of split molds each having a hollow part of a desired shape is inserted through the hollow part of the mold, and then placed in the hollow part and held in the shape of a clamp.
A molten material made of a thermoplastic resin G having a melting point lower than that of the resin cheese 1--b is injected from the focused part into the hollow part inside the mold, filled, and then subjected to a cooling treatment. The gist of the present invention is a method of fixing small-diameter resin tubes in an interlocking arrangement, in which the straight pipe portions of the resin tubes are solidified, and thus fixed by embedding the straight pipe portions of the resin tubes in a lump-wrapping manner as a clamp body is formed. (Function) Since the present invention relies on such a fixing method, due to the difference in melting point between the resin tube and the injection molded clamp body,
As the clamp body is molded, the fixing part on the resin tube side is molded and buried all at once, which eliminates the troublesome work of assembling the resin tube and makes it possible to securely fix it. Therefore, workability is significantly improved, and there is no worry of the resin tube coming off at the fixed part, and since the clamp body side is molded with a resin material whose melting point is lower than that of the resin tube, there is no possibility of collapse on the resin duplex side. , which eliminates deformation.

It is a cross-sectional view showing the state of injection molding in a mold related to the configuration of the aggregate array shown in the figure, in which (1) is a piece of 6 m/n + 3 wood, 8 m/m, which has been previously bent as desired. For example, there are a plurality of resin tubes made of nylon-11 material with a melting point of about 185°C, and the resin tubes (1) are made from a pair of split molds having rectangular hollow parts (3,3") inside facing each other. A mold (2,2") is inserted through the hollow part, and the straight pipe parts, which are arranged approximately parallel to each other with a gap maintained in the hollow part (3,3°), are placed in a sandwich shape. Then, from the spout (5) provided on one side of the mold, the hollow part (3,3°) is filled with nylon having a melting point lower than that of the resin tube (1), for example, about 170°C. - Injection pressure of 150 kg of molten material made of thermoplastic resin consisting of 12 materials
/'(m2) is injection-filled.Then, it is then cooled and solidified by flowing cooling water through the flow path (6), and then aggregated as the clamp body (4) is formed. The straight pipe parts of the arranged resin tubes (1) are cast and buried in a package shape to obtain a fixed assembly.It should be noted that (7) shows the inside of the resin tubes during injection and filling. This is an air vent hole.

な細径樹脂チューブの集合配列固定方法である。(Effects of the Invention) As explained hereafter, the method of gathering, arranging and fixing small diameter resin tubes according to the present invention is particularly advantageous in that the resin tube (1) and the clamp body (71) are not related to their mutual melting points. Since the fixing part is cast and buried in a packaged manner, the assembly of the resin tube (1) is not troublesome and can be constructed easily and reliably, resulting in significantly improved workability. At the same time, there is no need to worry about detachment at the fixed part.
Furthermore, by molding the clamp body (4) side with a resin material having a melting point lower than that of the resin dupe (1), it is possible to eliminate crushing and deformation at the fixing part of the resin tube side, and to ensure smooth circulation of the internal fluid. This is an extremely useful method for gathering, arranging and fixing small diameter resin tubes.
