AGGREGATE FOR MAKING HOLLOW CERAMIC ARTICLES BY CASTING Russian patent published in 2006 - IPC B28B15/00 B28B1/26 B28B5/02 

FIELD: process for casting hollow ceramic articles, possibly development and building of new equipment or modifying equipment of operating plants in porcelain-faience and majolica industry.

SUBSTANCE: aggregate includes vertically closed conveyer with cradles for casting molds; drive unit; casting section with metering devices; suction off device; control unit in the form of actuating and distributing cam mechanism electrically connected with drive of vertically closed conveyer and kinematically coupled with metering and suction devices. Aggregate also includes cradle locking unit in the form of spring-loaded rod with roller; roller; guides for cradles; drying chamber with upper and lower horizontal branches of vertically closed conveyer; boxes with nozzles and heating-ventilating system; vertical section with replacing member arranged over horizontally closed conveyer for additionally working articles. Boxes with nozzles for drying articles in molds are arranged over lower horizontal branch of vertically closed conveyer in drying chamber between casting section and vertical section. Boxes with nozzles for drying empty molds are arranged over upper horizontal branch of vertically closed conveyer in drying chamber along its whole length and over lower branch that is placed over casting section. Aggregate is also provided with apparatus for cleaning empty molds; said apparatus is placed in casting section in front of metering devices and mechanism for lifting-descending mold lids arranged in vertical section in position for taking articles out of molds. Apparatus for cleaning empty molds includes collector with vertical branch pipes having changeable tips. Said collector is placed on carriage moving vertically along guides and it is connected by means of flexible hose through filter and valve with receptacle of evacuation system of aggregate. Lid lifting-descending mechanism includes balance beam with comb mounted with possibility of rotation in bearing assemblies on carriage that may move on vertical guides.

EFFECT: enlarged assortment, improved quality of articles, lowered size and metal consumption, reduced cost of aggregate, reduced heat separation in industrial room.
