The 5 main points of the maintenance of precision molds 'hardware'

5 main points for maintenance of precision molds 1. The cutting edge of precision molds must be sharpened after long-term use, and the cutting edge surface must be demagnetized after grinding, and it must not be magnetic, otherwise it is easy to cause blockage. 2. Springs and other elastic parts are easy to be damaged in the process of use, and usually break and deform. The method adopted is to replace. In the process of replacement, you must pay attention to the specification and model of the spring. The specification and model of the spring are confirmed by the three items of color, outer diameter and length. Replacement can only be done when the three items are the same. 3. During the use of precision molds, the punch is prone to breakage, bend and gnaw, and the punch sleeve is generally gnawed. The damage of the punch and sleeve is generally replaced with parts of the same specification. The parameters of the punch mainly include the size of the working part, the size of the installation part, and the length dimension. 4. Fastening parts, check whether the fastening parts are loose or damaged. The method adopted is to find the parts of the same specification for replacement. 5. Material pressure parts such as material pressure plate, Uniglue, etc., discharge parts such as stripper plate, pneumatic ejector, etc. During maintenance, check the relationship between parts of each part and whether there is damage, repair the damaged part, check whether there is air leakage by pneumatic jacking, and take measures for specific conditions. If the trachea is damaged, replace it.
