A molding machine is disclosed which has a parting line of the molds at an acute angle to the horizontal. A continuous molding machine is disclosed wherein particulate matter such as sand and a binder is used to provide a succession of molds with cavities therebetween into which molten metal is poured to make a casting. The sand mold is constructed using a molding chamber and first and second pattern plates carrying patterns which face in opposite directions relative to the molding chamber. The sand is invested and the mold cured or hardened, then the pattern plates are withdrawn along opposing paths which are non-coincident. The completed sand mold is moved from the molding machine into a core setting area whereat cores are moved along the axis of the cavity which is at an acute angle to the horizontal for easy setting of these cores in prints of the mold cavities. Sprue and vent openings may also be drilled in this core setting area. The molds with the cores set therein are moved to a closing station whereat the mold is moved at an acute angle to the horizontal, generally parallel to the axis of the cavity, so that a first cavity is closed upon a second cavity of a previously completed mold. The line of molds is then moved horizontally to a metal pouring area. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
