METHOD FOR PRODUCING A ONE-PIECE CYLINDER HEAD FOR DIESEL ENGINES BY DIE-CASTING, AND DIE-CASTING MOLD FOR USE IN THIS METHOD

摘要

The method involves using a pressure casting mould in which a core is inserted to form the inlet duct of the cylinder head. The core comprises two sliders with common partition faces wherein the first slider has a side extension direction corresponding to the torsion channel whilst the second slider has a moulded torsion edge (8). An independent claim describes pressure casting mould wherein the second slider has a negative form for a torsion edge (8) disposed on the mouth of the inner section of the contour face defining the torsion channel.
