The fault analysis and solution of the injection mold

The cause of machine failure is often caused by improper operation and setting. Simple troubleshooting can be made through analysis.
Adjustment steps of mold locking force and low voltage protection:

1. （injection mold)Mold locking high pressure setting: 135bar, 10%; The low-pressure speed setting is 20%, and the low-pressure position setting value is 100mm; The low pressure time is set to 5 seconds.

2. (injection mold)Use the advance and retreat of mold adjustment to establish the mold locking force; The maximum value of the pressure gauge rise when the system pressure gauge is under high mold closing pressure shall prevail. Refer to the mold locking force oil pressure comparison table.

3. (injection mold)Set the low pressure position to zero after mold opening.

4. Press to close the die until the die contacts and release it immediately. At this time, assuming that the position of the moving die is "X", the low pressure position is set to "x + 1" mm.

5. Then set the low-voltage protection width: the low-voltage protection width is the distance from low speed to low voltage.

6. (injection mold)Set the low-voltage protection time to 1.2 seconds
