Casting mold producing method, involves disposing cast-in-place cylinder bore liner in seated position in contact with seating surface of seat, where chamfer becomes unseated from surface upon thermal expansion of liner

摘要

The method involves providing a cast-in-place cylinder bore liner (46) having a longitudinal axis, where the liner has chamfer formed on an end. A mold core is formed by a blown-in method, where the mold core includes a mold seat having a seating surface (112). The liner is disposed in a seated position in contact with the surface of the seat. The chamfer becomes unseated from the surface upon thermal expansion of the liner.
