Abstract A continuous molding machine having a stand with a top platform. Mounted on the top platform is a stationary plate in which a first pair of laterally spaced vertical shafts are rotatably supported. A laterally adjustable plate is also mounted on the top platform and it has a second pair of laterally spaced vertical shafts rotatably supported thereon. Adjustable pressure plate structure is mounted on the top platform to vary the lateral spacing between the stationary plate and the adjustable plate. Sprocket gears are mounted on each of the shafts and separate chains pass around the sprocket gears on the first and second pair of laterally spaced shafts. Secured to the outer surface of these chains are a plurality of pressure plates. Closed loop blets made of a flexible material such as vulcanized rubber pass around the pressure plates on the respective chains and they have a plurality of mold cavities in their outer faces. The mold cavities have sprue cavities extending upwardly to the top of the belts and the individual sprue cavities are connected together by a runner cavity so that the articles being cast are connected together in one continuous piece of molded material. A cover encloses the first and second closed loop conveyors and it has a window in one of its walls for observing and monitoring the molding operation.
A continuous casting machine comprising a stand, a first pair of laterally spaced shafts rotatably supported on said stand, said shafts being positioned parallel to each other and being vertically oriented, a first closed loop belt having a plurality of mold cavities formed in its outer face, a first conveyor means mounted on said first pair of laterally spaced shafts with said conveyor means supportably mounting said first closed loop belt so that it passes around said shafts, a second pair of laterally spaced shafts rotatably supported on said stand, said shafts being positioned parallel to each other and being vertically oriented, a second closed loop belt, a second conveyor means mounted on said second pair of laterally spaced shafts with said conveyor means supportably mounting said second closed loop belt so that it passes around said shafts, wherein said first conveyor means comprises sprocket gears mounted on said first pair of shafts and having a chain also passing around said sprocket gears, and wherein said chain has a plurality of pressure plates mounted on its outer face that contact the inner surface of said first closed loop belt, and wherein said first closed loop belt is made of elastic material, and wherein said mold cavities are connected to a plurality of sprue cavities that extend upwardly to the top of said belt and also said sprue cavities are connected to each other by runner cavities thereby allowing multiple pieces to be cast in a continuous piece of molded material, and wherein said stand comprises a stationary plate in which said first pair of laterally spaced shafts are rotatably supported and an adjustable plate in which said second pair of laterally spaced shafts are rotatably supported for varying the lateral spacing between said stationary plate and said adjustable plate.
