Troubled by the pressure ratio adjustment problem of Shanxing injection molding machine? don’t worry! PHP editor Banana has brought you detailed solutions. This article will delve into how to easily adjust the pressure ratio of Shanxing injection molding machine to help you solve production problems. Read on for step-by-step instructions and expert advice to easily control your injection molding machine's pressure parameters.
Under normal circumstances, the flow and pressure of the injection molding machine have been strictly adjusted and generally do not need to be adjusted again. In special circumstances, it is necessary to re-adjust the pressure and flow limit control potentiometers on the computer CPU. Inspection method of CNC pressure linear proportional control:
1. The positions of the four "flow and pressure limit control" potentiometers on the computer CPU unit.
2. The preset parameters are to adjust the four-level injection speed to 50 and the pillow pressure to 00.
3. Start the oil pump motor. When the temperature of the sol barrel reaches the sol temperature, press the manual injection button to make the screw bottom. The oil pressure gauge should indicate a pressure value below 20 kilograms. The pressure minimum control potentiometer can be used to adjust. Turning counterclockwise can reduce the pressure.
4. Preset parameters can be used to increase the pillow pressure by steps. The oil pressure gauge indication should be increased proportionally. When the pressure numerical control value of the pillow pressure reaches 50 or 90, the oil pressure gauge should be within an error of 2.5 kg. If it exceeds the adjustment Minimum potentiometer.
You are talking about the temperature display showing 999 degrees. This is a common problem with Shanxing computers. Is every paragraph 999?
If so, check whether the 44-core wire between the thermocouple board and the motherboard is loose. If not, the temperature control IC in the motherboard may be faulty. Prepare to replace the motherboard or thermocouple board.
After repair, pay attention to check whether the heating coil is leaking. The thermocouple may be over-current, causing the temperature control part of the motherboard to malfunction. Hope this helps.
