Abstract
A lubrication control system for use with or in a metal casting mold. Aspects of the invention include a lubricant flow stop or plug which prevents or controls the flow of lubricant from the mold during non-casting times.
Claims16
A lubricant control system for use with a metal casting mold, comprising:
- a lubrication conduit disposed to receive a flow of lubricant from a lubricant inlet and distribute lubricant to a lubricant outlet around a mold cavity;
- and
- a lubricant conduit plug disposed to prevent the flow of the lubricant through the lubricant outlet upon the occurrence of a pre-determined condition.
A lubricant control system as recited in claim 8, and further wherein the pre-determined condition occurs as a result of the termination of casting.
A lubricant control system for use with a metal casting mold table, comprising:
- a lubrication conduit disposed to receive a flow of lubricant from a lubricant inlet and distribute it to lubricant outlets around a mold cavity;
- and
- a lubricant flow stop means disposed near the lubricant outlet to prevent the flow of the lubricant back through the lubricant outlet upon the occurrence of a pre-determined condition.
A metal mold comprising:
- a mold framework with a mold bore for receiving molten metal;
- a lubricant control system integral with the mold framework, the lubricant control system comprising:
- a lubrication conduit disposed to receive a flow of lubricant from a lubricant inlet and distribute lubricant to lubricant outlets around a mold cavity;
- and
- a lubricant conduit plug disposed to prevent the flow of the lubricant through the lubricant outlet upon the occurrence of a pre-determined condition.
A method for controlling the lubricant in a metal casting mold, comprising the following:
- providing a metal casting mold with a mold cavity, the metal casting mold including at least one lubricant conduit disposed to receive a flow of lubricant from at least one lubricant inlet and to distribute the lubricant to a plurality of lubricant outlets positioned around the mold cavity;
- providing at least one lubricant conduit plug corresponding to the plurality of lubricant outlets, and disposed to prevent the flow of the lubricant through the plurality of lubricant outlets upon the occurrence of a pre-determined condition;
- and
- activating the lubricant conduit plugs to block the flow of lubricant through the plurality of lubricant outlets.
