To provide a casting frame for casting capable of surely connecting a hook-shaped clamp installed in an upper casting frame to a pin projected in a lower casting frame, by allowing its variation, even if a height of a sand-attached part projected to the parting surface side from the upper-lower casting frames, is varied more or less.
The casting frame for casting comprises the upper-lower casting frames for joining the frames by molding a sand casting mold in an internal space, a plurality of clamp members 4 rotatably installed in the upper casting frame 1 and provided with a groove part 6 and a plurality of pin members 7 installed in the lower casting frame 2 and engaging with the clamp members 4. The groove part 6 of the clamp members 4 is formed with an action surface circular arc 8 contacting with the outer periphery of the pin members 7. The center of this action surface circular arc 8 and the rotational center 5 of the clamp members 4 are dislocated to cope with a height variation in the sand-attached part.
