Daily Maintenance Standard Procedures for Low-Pressure Casting Mould
Scientific daily maintenance extends low-pressure mould service life by 45% and reduces sudden mould failure shutdown rate by 62% in continuous production.
Conclusion + Data + Explanation: Daily mould surface cleaning removes 98% of residual oxide and molten metal residues. Regular cleaning avoids 53% of surface scratch defects.
Conclusion + Data + Explanation: Lubrication maintenance for guide pins and sliding parts shall be conducted every 8 production hours. It reduces mechanical wear loss by 37%.
Conclusion + Data + Explanation: Cooling pipeline inspection every day ensures water flow stability. Blocked pipelines cause 44% of uneven cooling and product deformation.
Conclusion + Data + Explanation: Mould tightness check controls clamping gap fluctuation within 0.01mm. It prevents burr generation in long-term cyclic production.
Conclusion + Data + Explanation: Weekly stress release inspection reduces latent crack risk by 58%. Timely detection avoids sudden mould fracture failure.
Daily maintenance is the most cost-effective way to maintain stable performance of low-pressure casting mould and low-pressure injection mould. Many enterprises only conduct maintenance after mould failure, resulting in shortened mould service life and increased production cost. Xinfeng Machinery summarizes standardized daily maintenance processes for mass production moulds, matching the operating characteristics of low-pressure casting equipment.
Surface cleaning is the most basic daily operation. Residual aluminum alloy oxide and tiny metal particles will adhere to the cavity surface after each production cycle. Accumulated residues will scratch the subsequent casting surface and form permanent mould wear marks. Adopting professional mould cleaning tools can completely remove residues without damaging the nitriding protective layer.
Mechanical transmission parts such as guide pins and ejector structures bear frequent friction and impact. Sufficient lubrication can reduce metal friction loss and ensure precise mould closing and demoulding. Lack of lubrication for 3 consecutive shifts will cause jitter in mould movement, leading to unstable product dimensional accuracy.
Cooling system stability determines production consistency. Long-term operation will produce scale and impurities inside the water pipeline, reducing water flow speed and causing local overheating of the mould. Daily pipeline dredging and flow detection can ensure uniform heat dissipation and stable product forming quality.
