Method for pressure casting one-piece cylinder head of diesel engine uses pressure casting mould with two part core whose second slide forms torsion edge

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.
