Description

technical field

[0001] The invention relates to a die-casting machine measurement and control system and a control method thereof, in particular to a die-casting machine control and test system based on a Windows graphic interface, which belongs to the category of digital manufacturing. Background technique

[0002] The quality of die-casting parts is directly related to many process parameters in the die-casting process, such as the closing force of the die-casting machine, injection force, injection speed, pressurization time, etc. At present, most of the action control of the die-casting process uses a programmable logic controller (abbreviated as PLC) as the main control computer. Chinese patent CN02250448.6 "Intelligent control device for die-casting machine" includes a touch screen, a programmable controller, a digital-to-analog converter, a proportional amplifier, and an operating switch. The touch screen displays the machine's operating conditions and fault alarms. ...
