The convex part 25A for heat-sealing with the member 30 is formed.

도면부호 30은 제 2런너부재이다.Reference numeral 30 is a second runner member.

상기 제 2런너부재(30)는 도 3,4에서와 같이 상기 제 1런너부재(20)의 각 런너(21,22,23,24)와 이등분으로 대응되게 연결되도록 분할면(35)을 갖는 플라스틱 성형된 런너(31,32,33,34) 및 상기 런너(31,32,33,34)와 연장되어 이등분으로 분할되어 분할면(36)을 갖고 플라스틱 성형된 플래늄챔버(37)를 가지며, 상기 런너(31,32,33,34)의 타단에는 실린더헤드의 각 포트와 연결되는 플랜지부(38)를 일체로 형성하고 있다.As shown in FIGS. 3 and 4, the second runner member 30 has a split surface 35 so as to correspond to the runners 21, 22, 23, and 24 of the first runner member 20 in equal portions. A plastic molded runner (31,32,33,34) and extended to the runner (31,32,33,34) and divided into two parts having a divided surface (36) and having a plastic-formed platen chamber (37); On the other end of the runners 31, 32, 33 and 34, a flange portion 38 connected to each port of the cylinder head is integrally formed.

그리고 상기 제 2런너부재(30)의 분할면(35)에는 상기 제 1런너부재(20)의 분할면(25)에 열융착시키기 위해 철부(35A)를 형성하고 있다.In addition, a convex portion 35A is formed on the divided surface 35 of the second runner member 30 to heat-bond the divided surface 25 of the first runner member 20.

도면부호 40은 플라스틱으로 사출 성형된 플래늄챔버부재이다.Reference numeral 40 is a planar chamber member injection molded of plastic.

A convex portion 41A is formed to vibrately fuse the convex portion 36A of the planar chamber 37 side of the second runner member 30.

이같이 구성된 상기 3개의 단품으로 된 제 1런너부재(20), 제 2런너부재(30) 및 플래늄챔버부재(40)의 각 분할면(25)(35)(36)(41)을 상호 순차적으로 진동융착을 하게 되면 각 철부(25A와35A)(36A와41A)가 열변형으로 서로 융착되어 각각의 분할면(25와35)(36과41)이 접합되게 되어 일체형의 흡기매니폴드(10)가 제작되는 것이다.The divided surfaces 25, 35, 36, and 41 of the three single-piece first runner member 20, the second runner member 30, and the planar chamber member 40 configured as described above are sequentially sequential to each other. When the vibration welding is performed, the respective convex portions 25A and 35A (36A and 41A) are fused to each other by thermal deformation, and the respective divided surfaces 25 and 35 and 36 and 41 are joined to each other to form an integrated intake manifold 10. ) Is produced.

Compared to the intake manifold manufactured by weight, the weight is considerably reduced, which can reduce the weight of the car body.

또한 플라스틱의 가격이 상대적으로 주물에 비해 저렴함으로 흡기매니폴드(10)의 단가를 대폭 낮출 수 있고, 대량 생산에도 적합한 이점을 갖는다.In addition, since the price of the plastic is relatively inexpensive compared to the casting, the unit cost of the intake manifold 10 can be significantly lowered, and it is also suitable for mass production.

상술한 바와 같이 본 발명에 의하면 흡기매니폴드를 3개의 단품인 제 1런너부재와 제 2런너부재 그리고 플래늄챔버로 분할하여 플라스틱으로 사출 제작함으로써, 대량생산에 적합하고, 제작단가를 낮출 수 있을 뿐 아니라 중량을 대폭 감소시켜 차량의 경량화를 꾀할 수 있는 장점이 있다.As described above, according to the present invention, the intake manifold is divided into three single-piece first runner members, second runner members, and planar chambers and injected into plastic, thereby making it suitable for mass production and lowering manufacturing costs. In addition, there is an advantage that can significantly reduce the weight to reduce the weight of the vehicle.
