Method and device for casting a piston for an internal combustion engine |
摘要 |
In a method for casting a piston for an internal combustion engine, after solidification of the surface layer in the region of the piston-pin bores (12), at least one mandrel provided there is withdrawn and the region of at least one piston-pin bore (12) is cooled by coolant supplied through at least one mandrel. A device for casting pistons for internal combustion engines has at least one mandrel which can be withdrawn from the region of a piston-pin bore (12) and through which a coolant for cooling the region of the piston-pin bores (12) can be supplied. |
