What are the four main points of plastic mold maintenance?
1. Springs and other elastic parts are easy to be damaged during use, and usually break and deform. The method adopted is to replace, and must pay attention to the specification and model of the spring during the replacement process. The specification and model of the spring are confirmed by the three items of color, outer diameter and length, and can be replaced only when the three items are the same. The quality of the spring is better imported,
2: In the process of plastic mold processing and use, the punch is prone to breakage, bend and breakage (Shanghai Plastic Mold), and the punch sleeve is generally broken. 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.
3: 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.
4: Pressing parts such as pressing plates, Uniglue, etc., unloading parts such as stripping plates, pneumatic ejectors, 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 in the pneumatic jacking material, and take measures for specific conditions, such as replacing the damaged air pipe.
