PURPOSE: To mechanize the take-out of the insert member and its press-fitting work to dies by providing the chuck mechanism and link mechanism interlocked to cylinders.

CONSTITUTION: When the rod of a cylinder 27 is extended, a backing plate 28 contacts a stopper 38 and is suppressed, causing the cylinder 27 to move. Thereby, the insert member of the feed part 7 is inserted into a chuck 32. Next, when the cylinder 27 is contracted, the chuck 32 retreats to take out the insert member from a feed part 7, Thence, when a cylinder 22 is contracted, one link 12 of two sets of parallel links and the gear 18 coupling to this turn clockwise. Then, the gear 19 intermeshing with the gear 18 and link 16 turn counterclockwise. This causes link mechanisms 10, 11 to develop to horizontally move the chuck 32 toward a die-casting machine 1 and let it opposite to a die 5. Next, when the cylinder 27 is extended, the backing plate 28 contacts the stationary die and after this, the cylinder 27 moves to push the insert member into the die 5 by way of a pushing frame.
