Mold Maintenance

- Sep 10, 2018 -

1, processing enterprises should be equipped with a CV card, detailed records, statistics of their use, care (lubrication, cleaning, anti-rust) and damage, according to which parts, components have been damaged, the degree of wear and tear to provide information on the discovery and resolution of the problem, as well as the mold molding process parameters, products used materials,To shorten the commissioning time of the mold, improve production efficiency. 

2, the processing enterprises should be in the injection molding machine, mold normal operation, the testing of various properties of the mold, and the final molded part size measurement, through these information can determine the existing mold state, find the cavity, core, cooling system and parting surface damage, according to the information provided by plastic parts,Can determine the mold damage and repair measures. 

3, to the mold several important parts of the key tracking detection: the role of the ejector, guiding components to ensure that the mold opening and closing movement and plastic parts, if any part of the damage and stuck, will lead to production, it should always keep the mold thimble, guide column lubrication (to choose the most suitable lubricant), and regularly check the thimble, If the Guide column and other deformation and surface damage, once found, to timely replacement; After a production cycle, to the mold work surface, motion, guiding parts coating professional Antirust oil, especially should pay attention to the gear, rack mold bearing parts and spring mold elastic strength protection, to ensure that it always in the best working condition; With the continuous production time, the cooling channel is easy to deposit scale, rust, silt and algae, so that the cooling flow section becomes smaller, cooling channels narrowed, greatly reducing the heat exchange between the coolant and the mold, increase the production costs, so the cleaning of the convection channel should pay attention to; For hot runner molds, The maintenance of heating and control system is helpful to prevent the occurrence of production failure, so it is particularly important.Therefore, each production cycle after the end of the mold should be the belt heaters, rod heaters, heating probes and thermocouples, such as the use of ohmmeter measurement, if damaged, to be timely replacement, and mold resumes to compare, do a good record, so that timely detection of problems, to take countermeasures. 

4, to pay attention to mold surface maintenance, it directly affect the surface quality of products, the focus is to prevent corrosion, therefore, the choice of a suitable, high-quality, professional anti-rust oil is particularly important. When the mold finished production tasks, according to different injection molding to take different methods to carefully remove residual injection molding, copper rods, brass wire and professional mold cleaning agent to remove residual injection mold and other sediments, and then air dry. Disable the cleaning of hard objects such as wire and steel bars to avoid scratching the surface. If corrosive injection molding caused by Rust point, to use grinding machine grinding polishing, and spraying professional antirust oil, and then put the mold in a dry, cool, dust-free storage.
