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

A permanent mold casting system has a modularized architecture and remote placement of certain portions of the casting system. The casting system has a frame and a casting module supported on the frame is adapted to receive a plurality of molds for casting articles from a fill material according to a casting process. The casting module includes first motive actuators for moving at least portions of the molds during the casting process. An accessories module is supported on the frame and comprises at least one accessory device and second motive actuators for selectably positioning the accessory device in relation to the casting module. A utility module is located remotely from the frame and comprises motive power supplies coupled to the first and second actuators. The utility module also comprises a programmable controller coupled to the motive power supplies for controlling the casting process.

Modularized permanent molding machine with multiple molds

Apparatus for making a cast article includes a rotary table with a drive for indexing the rotary table to a plurality of rotational positions. A molten metal supply apparatus is placed at a first fixed location adjacent to said rotary table. A plurality of casting machines are supported at predetermined spacings on the rotary table, each respective casting machine having a respective holding furnace feeding a respective stalk tube and having a molten metal inlet port for receiving molten metal from the molten metal supply apparatus when the respective casting machine is indexed to a fill position adjacent the first fixed location. Each respective casting machine is adapted to receive one or more molds and has an open mold configuration and a closed mold configuration. A cast article removal apparatus is placed at a second fixed location adjacent the rotary table for removing the cast article from a respective casting machine when the respective casting machine is at an unload position adjacent the second fixed location and is in the open mold configuration.

Rotary casting system for pressurized casting machines

An apparatus for producing a plurality of cast products includes a plurality of molds, and a casting apparatus which casts products in the molds. A multi-level pallet carries the molds containing the cast products on at least two vertical levels. A loading apparatus loads the molds onto the multi-level pallet. A conveyor moves the multi-level pallet through a cooling area which is sufficient to cool the cast products for removal from the molds. An unloading apparatus unloads the molds from the multi-level pallet. In a method of producing a plurality of cast products, the products are cast in a plurality of molds. The molds are loaded onto a multi-level pallet which carries the molds on at least two vertical levels. The multi-level pallet is conveyed through a cooling area which is sufficient to cool the cast products for removal from the molds. After cooling, the molds are unloaded from the multi-level pallet.
