Key Considerations for Daily Maintenance of Fully Automatic Moulding Machines
To ensure efficient and stable operation, the following critical procedures must be strictly implemented:
I. Safety Operation Standards
Pre-operation preparation: Wear protective equipment (safety shoes, gloves), clear obstacles within the equipment radius, and verify emergency stop button functionality.
Power lockout: Before maintenance, disconnect power and hang warning signs. Use safety harnesses for elevated work.
Operation monitoring: During operation, closely monitor abnormal vibrations/noises. Immediately press the intermediate stop button if faults occur.
II. Daily Inspection & Cleaning
Daily checks:
Monitor oil pressure, oil temperature (hydraulic oil: 30-50°C), and air pressure values.
Inspect fasteners (anchor bolts, drive components) and pipelines (oil/air/water) for looseness or leaks.
Remove dust and residual sand from the machine body to prevent clogging of moving parts.
Cooling system maintenance:
Verify cooling water path clearance before startup; regularly descale coolers.
Check hydraulic oil level/quality and replace degraded oil promptly.
III. Key Component Maintenance
Lubrication management:
Lubricate moving joints periodically (daily/weekly/monthly) using specified oils in controlled amounts.
Prioritize maintenance of ram racks and jolting pistons: clean rust with kerosene and replace aged seals.
Ram & jolting system:
Regularly inspect ram swing responsiveness, clear track debris, and adjust air inlet pressure.
Address weak jolting by troubleshooting clogged filters, insufficient piston lubrication, or loose bolts.
IV. Preventive Maintenance
Electrical system:
Monthly: Clean dust from control cabinets, inspect wire aging, and tighten terminals.
Production coordination:
Notify sand mixing processes during shutdowns to prevent sand hardening; clean mold boxes and spilled iron slag post-pouring.
Maintain maintenance logs documenting fault symptoms, actions taken, and part replacements.
V. Periodic Maintenance Schedule
Cycle Maintenance Tasks
Weekly Inspect air/oil tube seals and filter status.
Monthly Clean control cabinets; calibrate positioning accuracy.
Semi-annually Replace hydraulic oil; comprehensive wear parts inspection.
Note: Operators must be certified and receive regular fault analysis training (e.g., 5Why method) to optimize maintenance strategies.
