Electromotive injection molding machine and power supplying method of electromotive injection molding machine

摘要

To provide a power supplying method that can reduce the maximum power of an electromotive injection molding machine including a power supplying apparatus having a predetermined power storage circuit. A power supplying apparatus for supplying power to servo amplifiers is configured by an AC/DC converter and a predetermined power storage circuit. In a process of a molding cycle except for an injection process, power is supplied from the AC/DC converter, and the power is stored in the power storage circuit. In the injection process, the AC/DC converter and the power storage circuit are controlled in conjunction with each other to supply the stored power, which is required when performing the injection process, from the power storage circuit, so as to prevent the AC/DC converter from supplying an excessive amount of power.
