Abstract

PURPOSE: To easily produce castings excelling in positioning of pipe and cast part in a small number of man-hour, by applying internal chill to the insert pipe and press working the end of pipe at the same time, when die casting.
CONSTITUTION: An insert pipe 1 forming a locking groove 2 is placed on specified position in dies 3, 4 for die casting, and the dies 3, 4 are closed. A pressurizing device equipped with an expanding punch 5 for the end of insert pipe 1 at the tip of provided, and the punch 5 is advanced, and the insert pipe 1 is expanded from the end by a specified range. Next, enclosing the insert pipe 1, molten alloy is poured into a cavity 7 for casting formed by the dies 3, 4, and the insert pipe 1 is inserted enclosing the insert pipe with the alloy. The punch 5 is drawn out, the dies are opened, and the cast product having the insert pipe 1 contained therein is taken out. Since the insert pipe 1 is press-fitted to a receiving member 6 by means of the punch 5, the position never varies, so that the positioning with the cast part may be achieved at high precision.
