  • Patent number: 6994148
    Abstract: A casting machine furnace apparatus that includes a furnace adapted to receive molten metal is described herein. The furnace includes an outer wall structure, a cover adapted to seal the furnace, a source of fluid, and a casting apparatus in fluid communication with the molten metal. The fluid is supplied into the furnace for applying fluid pressure on the molten metal. The application of fluid pressure on the molten metal causes the molten metal to supply the casting apparatus. The outer wall structure of the furnace is provided with a plurality of exhaust ports where the ports are provided in the outer wall structure at predetermined locations. The ports are selectively controllable between a first closed position, where the exhaust ports do not allow air to be exhausted from the furnace, and a second opened position, where the exhaust ports enable air to be exhausted from the furnace.

  • Patent number: 6627146
    Abstract: This invention relates to a casting machine furnace apparatus including a casting machine furnace, a supply furnace in fluid communication with the machine furnace and operative to supply a molten metal to the machine furnace, and a stopper module device disposed in a fluid path between the casting machine furnace and the supply furnace. The stopper module device includes a block housing and a stopper assembly. The block housing includes an inlet opening and an outlet opening, and is disposed in the fluid path. The stopper assembly is supported for movement relative to the inlet opening of the block housing between a working position, wherein the molten metal flows from the supply furnace to the casting machine furnace, and a non-working position, wherein the flow of molten metal is prevented.
