サージタンクの製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for manufacturing a resin surge tank mounted on a vehicle engine.

されている。[Prior Art] Many vehicle engines have a surge tank interposed in their intake system to ensure stable intake. In the past, surge tanks were commonly made of metal, such as welded aluminum die-cast assemblies, but since there is a limit to how much weight can be reduced with metal, recently, surge tanks have been replaced with metal ones. It has been proposed to use a surge tank molded from a strong and lightweight polymeric resin material such as nylon.

が望ましい。 However, if the surge tank is simply made of resin, there is a risk that its strength will be insufficient and that it will not be able to fully exhibit the necessary functional durability. In particular, when such a surge tank is employed in a supercharged engine, there is a high risk that the surge tank, which is a pressure vessel, will burst due to internal pressure during use. Therefore,
When the surge tank is made of resin, it is desirable to mold it with resin containing a reinforcing material such as glass fiber.

る。 In addition, when molding a resin surge tank, if you can use a one-piece product made by blow molding, you can manufacture it.
Assembly is simplified and convenient. However, when attempting to make a rectangular shaped container such as a surge tank by blow molding, uneven thickness inevitably occurs due to uneven molding conditions, making it impossible to obtain a product with uniform thickness. Therefore, application of blow molded products to this type of pressure vessel is unsuitable.

溶着することが提案されている。 Therefore, when planning to replace the surge tank with a resin surge tank, it is currently necessary to use the split assembly. In other words, the surge tank pieces that have been molded into a plurality of pieces must be injection molded using a mold, and then they must be joined and integrated. At that time, if a solvent or adhesive can be used, it can be relatively easily joined, but from the viewpoint of reliability of joint strength, etc., the joined parts of each segmented surge tank piece are rubbed together and thermally welded. It is proposed that.

る。[Problems to be Solved by the Invention] However, when the joint parts of the surge tank pieces are frictionally welded together in this way, the reinforcing material for reinforcing the resin is exposed on the melted joint surface, and this reinforcing material is Friction between the joints often causes them to be crushed and dispersed, and end up adhering to the inside of the surge tank. and,
If this reinforcing material is carried from the surge tank to the engine intake system during engine operation, it can cause various problems. For example, when glass fiber or the like is used as a reinforcing material, crushed glass fiber adhering to the inside of the surge tank may enter the slow port of the vaporizer or other negative pressure passages for various controls. This may cause clogging.

を設けるようにしたことを特徴とする。[Means for Solving the Problems] In order to achieve the above object, the present invention provides a surge tank piece that is segmentally molded and contains a reinforcing material.
In thermally welding the joined parts by friction, a resin member that can be melted earlier than the surge tank piece and does not contain the reinforcing material is provided on the inner edge of the joined part. .

I will do it. Therefore, even if the reinforcing material exposed on the joint surfaces is crushed due to friction between the joint surfaces, this resin material melts first and closes the inner edge of the joint, so that the inside of the surge tank can also be seen from the joint of the surge tank pieces. This prevents the reinforcing material from penetrating and adhering to the inner wall surface, etc.

る。 In the example shown in FIG. 5, the inner edges of the joints 204 and 205 of one surge tank piece 202 and the other surge tank piece 203, which are made of a polymer resin such as 66 nylon containing glass fibers, are similar to the above. Recessed portions 211 and 212 are formed, and resin members 213 and 214 made of nylon 6 or the like that do not contain glass fiber are fitted into these recessed portions 211 and 212. In this case, welding surfaces 203a, 204a of surge tank pieces 203, 204
Resin members 213, 214 that protrude slightly more
Certain spaces j and k are provided on the welding surfaces 213a and 214a, respectively. In this way, when the surge tank pieces 202 and 203 are vibration welded together, the welding surfaces 213a and 214a of the resin members 213 and 214 are melted first, and the welding surfaces 202 and 203 are melted first.
a, 203a, and the welding surface 2
Remove burrs, etc. containing glass fibers from spaces j and k that try to enter the surge tank from 02a and 203a.
This makes it possible to reliably prevent glass fibers and the like from entering the surge tank.

とになる。 In the above embodiment, the surge tank piece was made of a polymer resin whose main component is 66 nylon containing glass fibers, but it is also possible to use a polymer resin whose main component is polypropylene etc. It can also be suitably applied to a surge tank piece that is divided and formed by including it. In such a case, a resin member such as polyethylene which has a slightly lower melting point than the surge tank piece and does not contain glass fiber or the like is provided at the inner edge of the joint of the surge tank piece.

る。[Effects of the Invention] As explained above, the present invention uses a resin member that does not contain a reinforcing material at the inner edge of the joint of the surge tank pieces that are separately molded, and that can be melted earlier than the surge tank pieces. Therefore, when the surge tank pieces are joined and integrated, the resin member can effectively prevent the reinforcing material from entering the surge tank. As a result, a method for manufacturing a highly reliable surge tank that avoids problems such as the reinforcing material contained in the surge tank pieces being carried into the various negative pressure passages of the intake system, the combustion chamber, etc. without reducing the strength. can be provided.
