4: fastening parts, check whether the fastening parts are loose, damaged phenomenon, the approach taken is to find the same specifications of the parts for replacement.
5: Pressure parts such as pressure plate, Yuli glue, etc., unloading parts such as stripping plate, pneumatic top material, etc.. Maintenance to check the parts of the accessories relationship and there is no damage to the damaged part of the repair, pneumatic ejector check for air leakage phenomenon, and take measures for the specific situation. If the air tube is damaged, replace it.
To several important parts of the mold to focus on tracking and testing: ejector, guiding parts of the role is to ensure that the mold opening and closing movement and plastic parts ejection, if any part of which is stuck due to damage, will lead to production stoppage, so it should be often to keep the mold ejector, guide column lubrication (to choose the most suitable lubricant), and regularly check the ejector, guide column, etc. Whether the deformation and surface damage occurs, once found, it is necessary to replace in a timely manner;
After the completion of a production cycle, the mold working surface, movement, guiding parts coated with professional anti-rust oil, especially should pay attention to with gears, rack and pinion mold bearing parts and spring mold elastic strength of the protection to ensure that it is always in the best working condition;
With the production time continues, the cooling channel is easy to deposit scale, rust, silt and algae, etc., so that the cooling runner cross-section becomes smaller, the cooling channel becomes narrower, greatly reducing the heat exchange rate between the coolant and the mold, increasing the production cost of the enterprise, so the cleaning of the runner should pay attention to;
For hot runner molds, heating and control system maintenance is conducive to prevent the occurrence of production failure, so it is particularly important.
