Abstract
A chill plate moves the mold structure into a furnace, A baffle is supported in an open central portion of an array of article molds by a plurality of support elements. The support elements extend through spaces between the article molds into engagement with a furnace to support the baffle during withdrawal of the article molds from the furnace. In one embodiment of the invention, the support elements are engaged with the furnace by rotating the chill plate through a small arc. When the article molds have been almost completely withdrawn from the furnace, the baffle plate is disposed adjacent to the upper ends of the article molds. At this time, the chill plate is again rotated to disengage the support elements from the furnace. When this happens, the baffle drops downwardly onto the chill plate. Disengagement of the support elements from the furnace may be facilitated by forming the support elements of a relatively brittle material which will break when pressure is applied against either the baffle or the support elements by the mold structure.
