Multiple pressure casting mold and molded product manufacturing method using same

A multiple pressure casting mold comprising:

• a mold part including
• upper and lower molds, each having molten metal injection ports and molded product accommodating parts for accommodating molten metal for a molded product;
• a rotary unit including
• a rotary body supporting the mold part on a bottom side of the mold part and configured to rotate the mold part so as to allow the molten metal injected through the molten metal injection ports to flow into the molded product accommodating parts;
• and
• a molten metal injection control unit for pressurizing the molten metal injected through the molten metal injection ports so as to allow the molten metal to flow into the molded product accommodating parts, together with the rotary unit, the molten metal injection control unit including
• a sub-frame disposed on and extending upward from the upper mold,
• upper and lower pressurizing cylinders, and
• upper and lower pressurizing parts,
• wherein the upper pressurizing cylinder is fixedly attached to the sub-frame such that the upper pressurizing cylinder rotates along with the upper mold, and
• the lower pressurizing cylinder is fixedly attached to the rotary body of the rotary unit such that the lower pressurizing cylinder rotates along with the rotary body, and
• wherein the upper pressurizing part is attached to a cylinder rod of the upper pressurizing cylinder, and
• the lower pressurizing part is attached to a cylinder rod of the lower second pressurizing cylinder.
