Abstract

PURPOSE: To considerably reduce the drying and hardening time for mulled sand by penetratively flowing the heated and compressed air blown from the two or more opposing surfaces of a product cavity part through the wave-soluble glue-contg. mulled sand filled in said cavity.
CONSTITUTION: A core box 19 filled with mulled sand in a cavity part 20 is placed on the central part of a molding board 16 in such a manner that the opening part at the bottom end of the part 20 comes right above small holes 18, 18. Next, a cylinder 2 is extended to move an elevating table 4 upward until the box 19 abuts on a clamping head 11. When the compressed air heated to prescribed temp. in a tank 5 is released through the vent holes 13, 3 of the head 11 and table 4 respectively by opening on-off valves 15, 7, the compressed air penetratively flows in the mulled sand in the part 20, and is exhausted through the small holes 21, 21 near the joining position. After required time, the air blowing is stopped, and the table 4 is moved downward to lower the box 19, thence the core is removed.
