Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a compact and durable die structure which can cast two cylinder blocks at once. SOLUTION: The die structure can cast two cylinder blocks W at once. The die structure includes: right and left inside slide cores 5a, 5b held between the two cylinder blocks W; hydraulic cylinder units 10, 11 respectively moving the right and left inside slide cores 5a, 5b; inclination holes 12, 13 respectively provided at the right and left inside slide cores 5a, 5b; and inclined pins 14, 15 provided in the upper die 2 inserted into the inclination holes 12, 13 at the respective prescribed clearances C1, C2. When the upper die 2 operates, the inclined pins 14, 15 press the wall faces of the inclination holes 12, 13, thus the right and left inside slide cores 5a, 5b move to the directions of die openings, respectively. Desirably, the clearances C1, C2 are different at the right and left inside slide cores 5a, 5b. COPYRIGHT: (C)2011,JPO&INPIT
