Insert casting type cylinder head

The utility model relates to a position inserted and casting type cylinder head, which comprises a cylinder head base part (2) and a cast iron insert piece (3), and is characterized in that the cast iron insert piece (3) is arranged at a fixing hole of the cylinder head base part (2) and a rocker arm bracket (1). As the cast iron insert piece is inserted into the position with easy thermal expansion under the state of the thermal engine of the utility model, the cast iron insert piece has small size and small deformation caused by the thermal expansion, which not only limiting controls the gap between a mandrel and a rocker arm, reduces the noise, but also reduces internal stress of the inserted and casting joint surface caused by the thermal expansion. The utility model has simple structure of the inserted and casting, and low manufacturing cost.
