<P>PROBLEM TO BE SOLVED: To provide a die for die casting and a casting apparatus for die casting provided with the die for die casting with which a formed body is easily separated from a core when the core is shifted in the direction crossing the shifting direction of a movable die after die-opening the die for die casting composed of the movable die and a fixed die. <P>SOLUTION: The die 1 for die casting, is provided with the fixed die 10, the movable die 20 and the core 30. The core 30 is shiftable in the direction crossing to the shifting direction of the movable die 20 and a part thereof is demarcated with a sprue 1b communicating with a cavity 1a. In the portion demarcated with the sprue 1b in the core 30, a pushing pin 31 with its tip part to be advanced/retreated to/from a runner at the tip part is arranged. The energizing force by a compressed spring 32 is acted to the pushing pin 31 and this pushing pin is retreated with casting pressure at the casting time, and shifted toward the sprue formed as the runner at the die-opening time after casting to separate the formed product 2 stuck to this portion of the core 30. <P>COPYRIGHT: (C)2004,JPO |
