Abstract
The present invention provides a cooling system for a low-pressure casting mold, in which a sprue is located at a side surface of a cylinder head to ensure a sufficient distance between a combustion chamber and the sprue so that a combustion chamber cooling system combined with water cooling and air cooling is provided in a lower mold, thus reducing cycle time. Moreover, the cooling system for a low-pressure casting mold in accordance with the present invention improves mechanical properties of a material used by reducing DAS and porosity.
