A mold for injection molding, the mold comprising:

• two or more cavity rows, each cavity row having a plurality of cavities;
• and
• a cooling flow path configured to allow a cooling medium to flow through the cooling flow path, the cooling medium cooling the cavities, the cooling flow path including:
• at least one supply port;
• a distribution conduit communicated with the supply port;
• a supply conduit communicated with the distribution conduit;
• a cavity cooling portion communicated with the supply conduit and provided to an outer periphery of the cavities;
• a discharge conduit communicated with the cavity cooling portion;
• a collecting conduit communicated with the discharge conduit;
• and
• at least one discharge port communicated with the collecting conduit,
• wherein the supply conduit and the discharge conduit are parallel to the cavity rows, and at least one supply conduit and at least one discharge conduit are provided for each cavity row,
• the distribution conduit and the collecting conduit have larger diameters than the supply conduit and discharge conduit, and
• the distribution conduit and the collecting conduit are arranged below the supply conduit and the discharge conduit such that the distribution conduit and the collecting conduit are provided at different heights from the supply conduit and the discharge conduit.
