Fault Analysis of Die Casting Machine Clamping and Mold Opening Systems（一）

Common Clamping Fault Analysis

1.Failure to Clamp

（1）Safety system intervention: Confirm front/rear safety doors are fully closed and limit switches are properly engaged

（2）Hydraulic system abnormalities: Inspect control valve operation in clamping circuit and solenoid integrity

（3）Ejector not reset: Verify ejector stroke settings and sensor signal status

Robotic arm position error: Check robot homing sensors and pneumatic control valve functionality

2.Low-pressure Clamping Faults

（1）Mold condition confirmation: Ensure no foreign objects in mold cavity and proper mold closure

（2）Parameter setting verification: Validate low-pressure clamping parameter configurations

3.Mechanical Component Issues

（1）Transmission component inspection: Regularly check wear conditions of key parts including toggle joints and links

（2）Cylinder maintenance: Maintain clamping cylinder internal cleanliness to prevent jamming

Common Mold Opening Fault Analysis

1.Failure to Open Mold

（1）Mold opening condition abnormalities: Check control valve operation status in mold opening circuit

（2）Hydraulic parameter confirmation: Verify mold opening pressure and flow speed settings

（3）Injection cylinder status: Ensure injection cylinder returns properly

2.Mold Installation Issues

（1）Clamping force adjustment: Precisely adjust clamping force following standard procedures

（2）Shutdown status management: Establish standardized procedures for stopping machine in mold opening position

3.Temperature Effect Management

（1）Thermal expansion compensation: Monitor and promptly adjust mold capacity after temperature rise

（2）Parameter optimization: Appropriately adjust opening parameters to overcome thermal expansion resistance
