1. An injection molding mold comprising:
a flow path through which a molten resin passes;
a main body portion including an introduction portion configured to introduce the molten resin into the flow path and a supply portion configured to supply the molten resin from the flow path to a cavity mold; and
a plug unit formed with a plug flow path which is a part of the flow path, the plug unit being attachable to the main body portion,
wherein a prevention portion configured to prevent a pressure loss from occurring when the molten resin passes through the flow path is formed at a portion of the plug flow path where a moving direction of the molten resin changes,
wherein the plug unit includes a plurality of base members,
wherein the plurality of base members includes:
a first base member formed with a straight portion of the flow path where the molten resin moves straight;
a second base member formed with a curved portion of the flow path where the moving direction of the molten resin changes; and
