Problems solved by technology

[0002] Injection molding machine is plastic injection molding equipment. At present, all-electric injection molding machines are mainly represented by products of Japanese companies. We can see the mechanical structure, electrical system, transmission system, etc. of their all-electric injection molding machines, and their structures can be imitated, but The control device and control method are the technical secrets of each company, and the software cannot be seen how to do it. For domestic injection molding machine manufacturers, only by relying on their own research and testing can they gradually make progress

Abstract

The invention belongs to the technical field of injection molding machine and provides an electric injection molding control device of an injection molding machine for controlling a driver. The control device comprises four closed loop control modules which are separately a position loop control module, a speed loop control module, a current loop control module and a pressure ring control module. The pressure loop control module is connected to the position loop control module, the pressure loop control module is connected to the speed loop control module, and the speed loop control module is connected to the position loop control module. The four closed loop control modules are controlled toward a purpose that the deviation between a command signal and a feedback signal is zero. The device provided by the invention has the advantages that by using the four closed loop control modules and combining several software switches, the device is used for controlling calculation and switching when the injection molding machine is in a some special working condition, so that the injection molding control precision is improved.
