Title:
シリンダブロック製造方法およびダミーライナ並びにダミーライナ鋳造方法
Document Type and Number:
Japanese Patent JP4446015
Kind Code:
B1
Abstract:
In a cylinder block manufacturing method, first and second dies (1 and 2) and a liner support (4) are provided to form a liner overcast configuration. The first and second dies (1 and 2) are positioned with respect to the liner support (4) and a dummy cylinder liner (7) made of an aluminum alloy such that the first die (1) contacts a pressing section (4b) of a first axial end of the liner support (4) and a first axially facing end of the dummy cylinder liner (7), and the second die (2) contacts a second axial end of the liner support (4) and a second axially facing end of the dummy cylinder liner (7). The first and second dies (1 and 2) are preheated to a prescribed temperature (T*) with the dummy cylinder liner (7) positioned on the liner support (4) by injecting molten aluminum alloy into a cylinder block molding cavity (6) to form a dummy cylinder block with the dummy cylinder liner (7) casted in the dummy cylinder block.
