PURPOSE:To make a device compact by providing center slide cores which are horizontally movable with respect to a movable plate, disposing slide guides to guide the center slide cores in the mold parting direction from a cope. CONSTITUTION:A pair of the center slide cores 14, 14 which are horizontally movable with respect to the movable plate 3 are provided and the slide guides 21 are disposed. A molten metal is poured into a cavity 10 and is solidified; thereafter, side slide cores 9 are retreated. A casting 23 rises together with the cores 14 and the cope 6 and ejector pins 20 of an upper stationary plate 1 contacts a plate 16 and a slide press plate 16 when the plate 3 is raised. The plat 3 ascends further and the cores 14 are guided by the guides 21, by which the casting 23 is easily parted from the mold. Since the cores 14 part the casting from the mold cooperatively with the rise of the plate 3, the entire part of the device is made compact.
