Abstract:
1. A method for filling a foam mixture in a cavity of a horizontally-split metal mold by pressurizing a foamed mixture including granular aggregate, water-soluble binders, and water, and injecting the mixture into a cavity of the metal mold, the method comprising: providing a horizontally-split metal mold having a filling port communicating with a cavity therein, which port is disposed at a side and near abutting surfaces of the horizontally-split metal mold; charging granular aggregate, water-soluble binders and water to a mixing bath through an opening thereof; inserting mixing blades into the mixing bath; mixing the granular aggregate, the water-soluble binders and the water by rotating the mixing blades to form a foam mixture; removing the mixing blades from the mixing bath; connecting a discharging port of the mixing bath to the filling port of the horizontally-split metal mold; closing the opening of the mixing bath; pushing up the foam mixture in the mixing bath to pressurize and discharge the foam mixture from the discharging port of the mixing bath, and inject the foam mixture into the filling port of the horizontally-split metal mold; and filling the cavity of the mold with the foam mixture while the mixture pushes out air in the cavity.
