The internal structure design of the cylinder head mold is a crucial aspect in mold manufacturing, because the cylinder head is an important component of the engine, and its internal structure directly affects the performance and efficiency of the engine.

Air duct design: The interior of the cylinder head usually contains air ducts connected to the cylinder to guide the flow of air and gas. The design of these ports needs to take into account the shape and arrangement of the cylinder to ensure adequate airflow into the cylinder and help optimize combustion. The internal structural design of the mold should accurately express these airways to ensure their geometric and dimensional accuracy.

Water channel design: The interior of the cylinder head also contains water channels for cooling. These water channels help dissipate heat and prevent the engine from overheating. The design of water channels needs to take into account the flow path and speed of the cooling water to ensure a uniform cooling effect. The internal structural design of the mold needs to accurately express the shape and connection method of these water channels to ensure the stability of the cylinder head in high-temperature working environments.

Spark plug hole design: There is usually a spark plug hole on the cylinder head, which is used to install the spark plug and play the role of ignition. The location and angle of the spark plug hole are critical to your engine's ignition system. The internal structural design of the mold requires precise expression of the geometric features of these spark plug holes, ensuring accuracy of their position and angle for correct installation of the spark plug.

Cylinder liner seat design: If a cylinder liner needs to be installed on the cylinder head, the internal structure design of the mold needs to take into account the position and fixation method of the cylinder liner. This involves the layout and positioning of holes to ensure the matching accuracy of the cylinder liner and the cylinder head, while ensuring the stability of the cylinder liner.

Oil gallery design: The interior of the cylinder head may also contain oil galleries for oil lubrication. The design of oil passages needs to take into account guiding and distributing the flow of engine oil to ensure adequate lubrication of all engine components. The internal structure design of the mold needs to accurately express the location and shape of these oil passages to meet the requirements of the lubrication system.

Strength and stability considerations: Internal structural design also needs to consider the overall strength and stability of the cylinder head. Through reasonable layout and reinforced structure, it is ensured that the cylinder head manufactured by the mold can withstand various forces and pressures when the engine is working, ensuring its stability and durability.
