ABSTRACT:
An automatic no-bake core and mold-making machine. A frame is rotatably mounted on a base and carries a plurality of core-forming patterns around its periphery. Plates surround the patterns to form a continuous, flat surface interrupted only by the pattern cavity. A mixing machine located adjacent to the rotating frame continuously pours sand and binder on the patterns and surrounding plates. A stationary plow under which the plates and patterns pass continuously wipes excess sand and binder into the next succeeding pattern passing below the plow. Means are provided for ejecting the cores from the patterns after they are cured.
