DIE CASTING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a die casting apparatus capable of rapidly solidifying molten metal remaining in a sleeve after injection while suppressing production of small solidified pieces.

SOLUTION: The die casting apparatus 100 includes a sleeve 20 for temporarily storing molten metal therein, and a sprue core 30 which is arranged at a sleeve fore end to guide the molten metal to a runner 14 communicating with a cavity. A guide groove 32 for guiding the molten metal to the runner 14 is formed in the sprue core 30. A highly thermal conductive material 34 having the thermal conductivity higher than that of a material of a sprue core section constituting the guide groove 32 is arranged at the front side of the sprue core facing the fore end of a plunger tip.
