Injection molding machine, injection molding apparatus, injection molding method, and injection molding program

An injection molding method for injecting a molten resin by causing a piston to be slid inside a cylinder, the method comprising:

• causing respective pistons to be slid inside a plurality of respective cylinders, causing a period during which a molten resin is injected from at least a first cylinder of the plurality of cylinders to overlap a period during which a molten resin is injected from a second cylinder of the plurality of cylinders for a first preset period, and causing the molten resin to be continuously injected from the plurality of cylinders.

A non-transitory computer readable medium storing an injection molding program configured to inject a molten resin by causing a piston to be slid inside a cylinder,

• wherein the program causes a computer to execute processing for controlling a plurality of drive parts that drive respective pistons so as to cause the respective pistons to be slid inside a plurality of respective cylinders, cause a period during which a molten resin is injected from at least a first cylinder of the plurality of cylinders to overlap a period during which a molten resin is injected from a second cylinder of the plurality of cylinders for a preset period, and continuously inject the molten resin from the plurality of cylinders.
