ABSTRACT:
A device for hardening a core mass containing sand contained within a foundry core forming tool includes a mixing device in communication with the foundry core forming tool for introducing a flow of a carrier gas stream enriched by catalyst vapor into the core mass containing sand; a first runnings system including a catalyst receiver tank containing catalyst, a first runnings pipe in communication with the catalyst receiver tank and the mixing device, a pump provided in the first runnings pipe for pumping catalyst from the catalyst receiver tank through the first runnings pipe, valve device provided in the first runnings pipe for dispensing catalyst into the mixing device, and a flow meter provided in the first running pipe between the pump and the valve device; a compressed air source in communication with the mixing device for providing a carrier gas stream comprised of air thereto; and programmed control device for controlling the valve device of the first runnings system and the compressed air source; wherein the valve device provided in the first runnings pipe may be temporarily utilized as a return pipe to the receiver tank by signal from the programmed control device so that pressure equalization in the first runnings system is obtained. The above device is useful for hardening a foundry core within a core forming tool of a core shooter by providing the core forming tool with such a device.
