Die Casting Machine Common Fault Analysis（二）

The previous article discussed the analysis of mold locking and opening failures in die casting machines.During the operation of die casting machines, various faults may occur. Timely and accurate diagnosis and problem resolution are crucial for ensuring production continuity.

Injection System Fault Analysis

1.Flying Material

（1）Nozzle and goose neck joint leakage: Check center alignment, ensure tight conical surface fit between nozzle and material pot

（2）Nozzle and mold joint leakage: Verify center alignment, inspect gate specification compatibility, adjust nozzle clamping force parameters

（3）Mold parting surface leakage: Readjust clamping force, check toggle mechanism wear, confirm mold parallelism

2.Injection Failure

（1）Safety conditions not met: Confirm safety door status and signal feedback

（2）Position detection abnormality: Check injection position reset status and mold clamping travel end signals

（3）Parameter setting issues: Verify injection pressure and time parameter settings

（4）Hydraulic system failure: Inspect injection circuit valve operation status

Auxiliary Mechanism Fault Handling

1.Ejector Mechanism Faults

（1）Electrical system: Check proximity switch signals and wiring connections

（2）Hydraulic system: Verify ejector circuit valve functionality

（3）Mechanical components: Inspect ejector plate guide rods, ejector flange plate, and related parts

2.Mold Adjustment System Faults

（1）Operating conditions: Ensure mold adjustment is performed in mold opening state

（2）Motor protection: Check mechanical component jamming, verify power supply stability
