Title: Aluminum-base complex material-made liner and its inserting method
Inventor: NAKAO YASUHIRO
IPC: F02F1/10
Filed: 2002-07-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for improving production efficiency, with which casting flash is hardly caused on the inner peripheral surface of a liner even when filling the molten metal into a mold with a prescribed pressure and the inner peripheral surface work in the following stage does not take time.  <P>SOLUTION: An aluminum-base complex material-made liner 10 has a thin wall part 13 deformed into the liner center 15 with molten aluminum pressure to one end 12 of the base part 11 of the liner 10. In the inserting method of the aluminum-base complex material-made liner, the liner is fixed into a cavity 35 in a mold 27 by inserting an insert material supporting shaft 26 into the liner and the cavity 35 is filled with molten metal. The liner is stuck to the insert material supporting shaft 26 by bending the thin wall part 13 with the pressure of this molten metal. A gap for attaching/detaching is arranged between the thin wall part 13 and insert material supporting shaft. Since the thin wall part in the liner is deformed with the pressure and closes the gap, the development of the casting flash on the inner peripheral surface of the liner can be restrained. In the inserting method, since the thin wall part is tightly stuck to the insert material supporting shaft by bending with the pressure of the molten metal, the molten metal is hardly leaked.  <P>COPYRIGHT: (C)2004,JPO
