Everything has a certain lifespan. In order to prolong the service life, we must know the correct maintenance method. The following is the correct maintenance method for rubber molds. First, the mold wear curve of regular maintenance is present in each mold. Die maintenance is to achieve abnormal wear in the field, and the number of stamping processes during this time is easy to learn. When the processing quantity is satisfied, the mold maintenance is realized, and the maintenance plan is not only easy to learn the maintenance items, but also easy to control the maintenance time. Second, improved maintenance In order to prolong the life of the mold, stabilize the quality, and facilitate maintenance, some improved molds are specially maintained. Third, daily maintenance refers to normal rubber mold cleaning, inspection, and oil removal. This work is usually to confirm that the mold is in a normal state, and abnormalities can be detected early. Fourth, there will be some changes in the processing of rubber molds repaired in accident status, and the country cannot continue to use them. Such as burrs become larger, wrong size, such as scars, burning of mold parts. Because of similar abnormality, the content of mold repair and maintenance is called accident. This maintenance is usually used until the near limit, if the time of the rubber mold maintenance cost is more important, the life of the mold is short. Because this is a sudden maintenance, there must be a planned shutdown of equipment, and emergency repairs.
