A MOLD FOR GRAVITY CASTING

摘要

The present invention relates to a mold for gravity casting comprising a lower mold; front and rear molds combined with the upper sides of front and rear sides of the lower mold; side molds consisting of left and right molds combined with the upper sides of the left and right sides to form molding space in the upper part of the lower mold; a riser core combined with the upper side of the side mold, and having a protruding core print in the predetermined position of both sides; and a pressurizing mold for preventing the riser core from being floated from the side mold due to the difference of specific gravity with molten mold supplied to the molding space through the riser core by being combined between the left and right molds and the riser core, and pressurizing the upper side of the core print mounted on a mounting part formed in the left and right molds.
