A mold temperature control system comprises a mold section having a cavity, a fluid circuit to distribute a flow of a conditioning fluid, the fluid circuit being positioned spaced apart from the cavity, a temperature sensor positioned in the mold to generate a signal representative of a temperature in the mold, a controllable supply of the conditioning fluid, and a controller for automatically initiating flow of the conditioning fluid through the fluid circuit in response to an initiation temperature and for automatically terminating flow of the conditioning fluid through the fluid circuit in response to a termination temperature.

Mold temperature control for casting system

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.

Stopper module device for a casting machine furnace apparatus

A method for producing a sand core includes the following steps: (a) providing a casting mold having a mold cavity, the casting mold including at least one first conduit and at least one second conduit; (b) providing a sand core disposed in the mold cavity; (c) providing a supply of conditioning gas to the casting mold, the conditioning gas being supplied to the casting mold through at least one of the first and second conduits; (d) providing a controller connected to the first conduit and the second conduit to selectively control the supply of conditioning gas; (e) providing a gas exhaust unit operatively connected to the casting mold; (f) operating the gas exhaust unit to cause the conditioning gas to be moved through the sand core; and (g) removing the sand core from the casting mold.
