The maintenance of plastic processing molds is very important. It should be known that any damage to the plastic mold processing factory may result in the suspension of production. Under the normal operation of the mold, test the performance of various parameters of the mold to determine the current condition of the mold. If there is a problem, the cavity, core, cooling system and parting surface can be detected for damage. At the same time, several important parts must be tested for key points: ejection, the role of the guide part is to ensure the mold opening and closing movement and ejection of the plastic parts, if there is damage to the parts, it may stop production. Therefore, if there is any wear or other problems, it is necessary to detect them early to prevent unnecessary attacks.

    So how to do maintenance work? After finishing a production cycle, apply professional anti-rust oil to the appearance, movement and guide parts of the mold. If there is protection of the elastic strength of the bearing part of the rack mold and the tension spring mold, to ensure that it is always in good working condition. These are very important. As the production time continues, the cooling channel is prone to deposit scale, rust, sludge, algae, etc., which makes the cross section of the cooling channel smaller and the cooling channel narrower. Therefore, attention should be paid to the cleaning of the channel to prevent the occurrence of problems in the channel. Early detection and maintenance, the runner can play its due role.

    There is a special problem here. For the hot runner mold, the maintenance of the heating and control system is helpful to prevent the occurrence of production problems, because this is very important. Therefore, after the end of each production cycle, the belt heater, rod heater, heating probe and thermocouple on the mold should be measured with an ohmmeter.If there is damage, it should be replaced in time and carried out with the mold resume. Make comparisons and make records so that problems can be discovered in a timely manner and countermeasures can be taken. The history of the mold can help us take a little detour, which is right. Take precautions, if you find a problem, you can take the right medicine.

    Needless to say, the appearance maintenance of the mold can not be ignored, it directly affects the appearance quality of the product, the main point is to prevent rust, so it is particularly important to choose a suitable, high-quality, professional anti-rust oil. The most important work is to prevent the onset of rust in time. When the mold is finished, the remaining injections should be carefully eliminated by different methods according to different injections. Copper rods, copper wires and professional mold cleaners can be used to eliminate the remaining injections and other deposits in the molds, and then air dried. Do not use tools such as iron wire to clean the inside of the mold to prevent the formation of internal and external damage, which is more likely to cause rust.
