4: Fasten the parts and check whether the fastening parts are loose or damaged. The method is to find the parts with the same specifications for replacement.
5: Pressing parts such as pressure plate, superior glue, etc., unloading parts such as stripping plate, pneumatic top material, etc. During maintenance, check the accessories of each part and whether there is any damage, repair the damaged part, check the pneumatic top material for air leakage, and take measures for the specific situation. Replace if the air tube is damaged. It is necessary to carry out key tracking and inspection on several important parts of the mold: the function of the ejection and guiding parts is to ensure the opening and closing movement of the mold and the ejection of the plastic parts. If any part is stuck due to damage, it will lead to production stoppage, so it should be kept frequently. Lubricate the thimble and guide post of the mold (use the most suitable lubricant), and regularly check the thimble, guide post, etc. for deformation and surface damage. Once found, replace it in time; after completing a production cycle, work on the mold surface. , sports, guide parts coated with professional anti-rust oil, especially the protection of the elastic strength of the bearing parts with gears, rack and die and the spring mold to ensure that it is always in the best working condition; as the production time continues The cooling channel is easy to deposit scale, rust, sludge and algae, so that the cooling passage section becomes smaller, the cooling passage becomes narrower, the heat exchange rate between the coolant and the mold is greatly reduced, and the production cost of the enterprise is increased, so the flow path is cleaned. Should pay attention to; for hot runner molds, the maintenance of heating and control system is conducive to prevent production failures, so especially To.
