Abstract

PURPOSE: A production method of a cylinder head having a fine structure by taking a point cooling method of a lower face of the cylinder head is provided. CONSTITUTION: A cylinder head(1) prevents the breakage of the lower face of a cylinder head cast with gravity by employing a point and a line cooling method, a Cu plate mold(4), and a normal steel mold(3) while producing the cylinder head. Also, a producing method for the cylinder head is composed of: making the upper face(10) of the cylinder head with a side mold(2); casting the lower face(20) with a normal steel mold and a Cu plate mold; and forming at least four of pipe cooling holes(21) at the lower face to form a point cooling hole(5). Thereby, forming the pipe cooling hole and the point cooling hole(22) at the lower face of the cylinder head enables to devise the fineness of a structure by cooling the lower face quickly.

실린더헤드 제조방법Cylinder head manufacturing method

본 발명은 실린더헤드 제조방법에 관한 것으로, 특히 실린더헤드의 하면을 포인트 냉각방식을 채용함으로서, 조직을 미세화한 실린더헤드 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cylinder head manufacturing method, and more particularly, to a cylinder head manufacturing method having a finer structure by employing a point cooling method on the lower surface of the cylinder head.

일반적인 실린더 헤드는 상기 실린더 헤드 위에 기밀 유지용 가스킷을 집어넣고 실린더와 같이 연소실의 일부를 형성하고, 그 외부에는 밸브기구, 흡기 및 배기 매니폴드, 점화플러그 등이 장치되어 있다.A typical cylinder head puts a gasket for airtight holding on the cylinder head and forms a part of a combustion chamber like a cylinder, and is provided with a valve mechanism, an intake and exhaust manifold, an ignition plug, and the like outside.

또한 엔진의 신뢰성(내구성)의 향상을 위해 직분시, DOHC, 4밸브 등의 채용이 증가되고 있다.In addition, in order to improve the reliability (durability) of the engine, employment of DOHC, four valves, etc. is increasing.

따라서, 상기 실린더 헤드는 엔진운전중 고온이 되므로 열전도가 잘되고 냉각효과가 높은 것이 요구되며, 혼합가스의 압축압력 및 연소압력을 받으므로 내마모성 내열성이 요구된다.Therefore, the cylinder head is required to have a high thermal conductivity and a high cooling effect because of the high temperature during engine operation, and wear resistance heat resistance is required since the cylinder head is subjected to the compression pressure and the combustion pressure of the mixed gas.

그러나, 현재의 실린더 헤드(1)는 도 1에 도시된 바와 같이, 일반 중력주조를 하여 수냉공법으로 냉각하고 있기 때문에 헤드하면의 깨짐 발생 및 이에 따른 클레임 발생 가능성도 점점 높아지게 된다는 문제점이 있었다.However, since the current cylinder head 1 is cooled by a water-cooling method by general gravity casting, as shown in FIG. 1, there is a problem that the possibility of cracking of the lower surface of the head and the subsequent occurrence of claims also increases.

본 발명의 목적은 상기의 문제점을 해소하기 위한 것으로, 일반 중력주조된 실린더 헤드의 하면을 일반스틸몰드, Cu 플레트 몰드 및 포인트 및 라인 냉각방식을 채용함으로서, 하면의 깨짐을 방지하는 데에 있다.An object of the present invention is to solve the above problems, by using a general steel mold, a Cu plate mold and a point and line cooling method on the lower surface of the general gravity-cast cylinder head, to prevent cracking of the lower surface .

본 발명은 상기와 같은 목적을 달성하기 위한 것으로, 실린더 헤드 제조방법에 있어서, 실린더 헤드의 상면은 사이드몰드로 하고, 하면은 일반 스틸몰드, Cu 플레트 몰드로 주조된 금형으로 하고, 상기 하면에 포인트 냉각구멍을 형성하여 포인트 냉각 및 라인 냉각하도록 함을 특징으로 한다.The present invention is to achieve the above object, in the cylinder head manufacturing method, the upper surface of the cylinder head is a side mold, the lower surface is a mold cast in a common steel mold, Cu plate mold, A point cooling hole is formed to allow point cooling and line cooling.

도 1은 일반적인 실린더헤드의 금형을 나타낸 도,1 is a view showing a mold of a typical cylinder head,

도 2는 본 발명의 실린더헤드의 금형을 나타낸 도.2 is a view showing a mold of the cylinder head of the present invention.

본 발명 도 2에 도시된 바와 같이 실린더 헤드 제조방법으로, 실린더 헤드(1)의 상면(10)은 사이드몰드(2)로 하고, 하면(20)은 일반 스틸몰드(3), Cu 플레트 몰드(4)로 주조하고, 상기 하면(20)에 파이프 냉각구멍(21)을 적어도 4개이상 형성하여 포인트 냉각구멍(5)이 형성됨에 그 기술적 구성상의 특징이 부여된다.In the cylinder head manufacturing method as shown in FIG. 2, the upper surface 10 of the cylinder head 1 is a side mold 2, and the lower surface 20 is a general steel mold 3, a Cu plate mold. Casting to (4) and at least four pipe cooling holes 21 are formed in the lower surface 20, so that the point cooling holes 5 are formed.

따라서, 상기와 같이 실린더 헤드(1)의 하면(20)에 파이프 냉각구멍(21) 및 포인트 냉각구멍(22)을 형성함으로서, 하면의 냉각을 좀더 빨리 하여 조직의 미세화를 얻을 수가 있다.Therefore, by forming the pipe cooling holes 21 and the point cooling holes 22 in the lower surface 20 of the cylinder head 1 as described above, it is possible to cool the lower surface more quickly and obtain finer structure.

본 발명은 실린더 헤드 하면의 Cu 몰드 및 포이트 냉각방식을 채용함으로서, 냉각속도를 기존의 냉각방식보다 빠르게 하여 조직의 미세화를 도모할 수가 있다.According to the present invention, by adopting the Cu mold and the point cooling method on the lower surface of the cylinder head, the cooling speed can be made faster than the existing cooling method, and the structure can be made finer.
