Abstract
PURPOSE:To mold a core by green sand by hadening the green sand packed in the cavity of a core box firmly by means of a screw shaft or eccentric shaft which is inserted into the cavity and is revolved then removing the screw shaft or the eccentric shaft. CONSTITUTION:An elevating table 9 placed thereon with a core box 12 is moved upward by the extension operation of a cylnder 7, to bring the box 12 into abutment on a hopper 10, thence the box 12 is clamped by means of the hopper 10 and the table 9. The green sand (a) in the hopper 10 is packed through the supply port 13 of the box 12 into a cavity 15 and a rotating and driving mechanism 3 is driven to revolve a screw shaft 6 and to insert the leading end of the shaft 6 through a through-hole 8 into the cavity 15 packed with the green sand (a), thereby hardening the green sand (a) firmly. The screw 6 is removed from the hardened sand (a) by operating the mechanism 3 and a cylinder 2. The box 12 is removed and the hardened core is removed by opening the box 12.
