Description

technical field

[0001] The present invention relates to a control device and method for improving the production efficiency of an injection molding machine using a frequency converter. Specifically, it is a method for eliminating the speed response delay time for switching between various process sections of the injection molding machine without reducing the productivity of the injection molding machine. Device and method for effectively saving energy. Background technique

[0002] In the traditional injection molding industry, the three-phase asynchronous AC motor usually used in the injection molding machine cannot change the speed, and the flow rate of the hydraulic oil output by the quantitative pump driven by it cannot be changed. When the injection molding machine is operating at a low speed, the excess flow flows through the relief valve. Back to the fuel tank, causing a large loss of energy.

[0003] An improved injection molding machine is to add a frequency conver...
