Molding apparatus and method

A casting method for casting parts providing a plurality of core mold assembly units configured within an external drag flask assembly and an external cope flask assembly, said method comprising:

• providing at least one riser vent to allow venting of said core mold assembly unit;
• providing at least one filling gate to allow introduction of molten metal into said core mold assembly unit;
• and
• providing mold components formed from molding sand each mated at a common split line defining a mold cavity which replicates the exterior features of said cast parts;
• wherein said external drag flask assembly includes
• a drag flask;
• a drag flask lining;
• a drag runner;
• and
• a drag runner support;
• wherein said external cope flask assembly includes
• a cope flask;
• a cope flask lining;
• at least one cope riser vent;
• at least one cope sprue filling port that allows molten metal to be poured through said cope sprue filling port;
• a cope runner which embodies at least one cope runner sprue filling port that allows molten metal to be poured through said cope runner sprue filling port;
• a cope runner support;
• and
• pouring molten metal through said cope sprue filling port, said cope runner sprue filling port, said cope and said drag runners, into said core assembly unit through said core mold assembly unit filling gate thereby filling said core mold assembly unit cavity to cast said parts.
