FIELD: metallurgy; may be used in production of large ingots with holes, mainly, from nonferrous metals. SUBSTANCE: mold has two side walls moving by reciprocation and two rotating end walls. Installed in side walls are pins which form holes in casting (ingot mold). Pins may be moved relative to walls in direction of joint. EFFECT: prolonged service life of mold due to stepped removal of casting from mold. 3 cl, 3 dwg
