Abstract
PURPOSE: To make the life of a die-casting device having two-stage injection functions longer by disposing an insert core to the inner plunger tip of the device and making its injection operation smooth.
CONSTITUTION: Molten metal 30 is supplied into an injection sleeve 21, and the piston rod 19a of a hydraulic cylinder 19 is pushed out to allow a moving die 12 to contact a stationary die 11. Thence, when the primary injection cylinder 23 is pushed out, outer and inner plunger tips 27, 28 and an insert core 29 ascend on one piece and press-feed the molten metal 30 into a casting space 13. When the secondary injection cylinder 24 is operated in succession to this, the inner plunger tip 28 and insert core 29 ascend to replenish and fill the relatively unfrozen molten metal 30 in the central part in the injection sleeve 21 into the casting space 13. Since the insert core 29 exists at this time, the operation of the inner plunger tips is smoothed and its insertion into the cast frozen metal is prevented, thus the service time is prolonged.
