Brand new servo hydraulic system design

The whole hydraulic system is driven by servo motor.
Reduce cycle time with synchronized design: melting PET at the same time while other movements are proceeding.
4 sets of nitrogen tank with high pressure filter.Injection, mold movement and ejecting are all controlled by Rexroth servo cylinder.
Equipped with separated filtering and cooling system for oil whose accuracy could reach 20um.
The advantage of servo control:
Low power consumption: When the machine is cooling or without any movement, the servo speed is less than 10 RPM which the energy consumption is almost 0.Whilenormal electrical motorspeedaround 1500RPM.
output point of servo hydraulic oil directly connected with the directional valve who control the movement to save energy. While normal machine has to though flow control valve.
Precision: Pressure sensor make the accuracy of servo hydraulic system reach 0.1bar.
Fast react: It only takes 0.12s for the pressure and speed to reach maximum output.

Control System
The project is leading by Mr. He -former HUSKY engineer who was in charging of the developing injection machine control system. Applied with his new generation PC based BECKOFF injection system control solution,
Demark machine could has following advantage:
1.Stable and fast cycle time.
2.Fast PCL execution time.
3.High performance PC and fast I/O capability.
4.Quick communication thought all control components.
5.Self-adjustment and self-adaption.
6.High level control algorithm for speed, pressure and temperature. High level control strategy for reducing energy consumption.
7.Friendly user interface design.
8.Intuitive icon design for fast learning and control.
9.Fast information reading by press less buttons.
10.Single function button design.
11.Clear and accuracy alarm function.
12.Detailed event log.
13.15 Inch touch screen, 2.1G dual core CPU, 3GB memory and 80GB hard drive equipped.
14.No touched electronic ruler with longer life time, and EtherCAT digital single with stronger anti-interference capability.

 

Temperature control system
Equipped heater from Italy and protector outside the heater.
The accuracy of temperature could reach ±1 degree with PID control.
The constant power module makes the mold temperature stable and non-influenced by the voltage.


Cooling Robot
Sliding and flipping unite are designed as a whole which could have more stability.
Easy adjustment for the distance between robot plate and mold.
Three station cooling plate.
LENZE servo motor and Alpha reducer make the movement accuracy and quiet.
Siemens vacuum pump.

 

Plasticization & Injection
Barrier design screw improved the plasticization effect.
Screw with chrome and the L:D ratio reach 25:1.
By equipping material storage unite, the machine could melting and injection at the same time.
Using servo motor from Germany for melting.
Back pressure could adjust on the control panel.

 

Clamping Unit
Special clamping parameter design for PET make the mold open & close stable and fast.
Strong mold plate make the mold get pressure balanced.
Square design which matching the mold.
Also compatible with HUSKY mold.
Ejection Unit
With more ejecting pin make better ejection.
Bigger ejecting force than normal machine.
Ejecting stop work with the light sensor which protect the mold.


Innovation on water and gas circuit
Centralized cooling water supply for mold, robot and auxiliary machine.
Stainless quick plug for cooling water.
Needle control in the mold use the MAC big volume valve which improve the speed and stability.
Using SMC valve for high pressure air and vacuum transmitting.
