Longhua intelligent cloud system is the latest research achievement of Chinese academy of sciences and has been awarded two national high-tech product certificates

Longhua intelligent cloud + Internet +  Internet of Things die casting machine program can control every process of die casting machine production in all parts of the world, automatically detect and troubleshoot faults, control pressure and speed, and enhance data analysis and other functions.This intelligent cloud system is equipped with a complete set of OMRON MITSUBISHI UBE, Visi Trak and Visi Trak injection control systems (including: YUKEN valve, REXROTH valve, power supply, controller, sensor magnetic bar, etc.).Compared with other domestic die-casting machines, longhua intelligent cloud die-casting machine is more professional, the system is more stable, can ensure the real-time system control.

The injection control system of die casting machine is a real-time and dynamically adjustable control system, which can be modified according to the die casting machine or specially used for new machine to improve the performance of the injection end.

The dynamic and real-time injection control of die casting machine is designed to improve injection control, injection programmability and repeatability as well as production flexibility.The advantages of the system include: the die-casting machine runs faster and more accurately;The flow of metal (liquid) during the whole shooting process is more stable;Longer processing time and less waste to achieve higher quality production.

The injection control system of die casting machine is composed of three main components:

Visi-trak position/speed sensor

For a closed loop injection control system, it is very important to know exactly the position and velocity of the piston during the whole injection process.The higher the accuracy, the better the "control" of the injection.The vis-trak sensor provides accurate, real-time position and speed feedback.

Computer - based S-T full digital motion controller

The microcomputer compares the feedback position/time value with the programming value to determine that there is no error.

Die casting machine speed control valve

The energy-saving guide speed control valve controls the speed by continuously adjusting the flow in the discharge side groove of the injection cylinder.The valve (especially the speed control valve designed for this application) includes: 1.two-stage jet tube electro-hydraulic energy-saving valve.2. Two-way balanced sliding column proportional flow control valve;3. The linear variable differential transformer (LVDT) provides feedback on the position of the speed valve groove for the motion controller.OMRON MITSUBISHI UBE SIEMENS special position sensor, sensor for non-contact, to minimize mechanical contact.This extends the life of the sensor, increases resistance to dust/oil, and reduces or completely eliminates the mechanical rebound resulting from the distortion of position/velocity results.
