Analysis on the cleaning method of plastic mold

Mold cleaning is a key process in mold maintenance and a bottleneck restricting mold maintenance. Because the speed of mold manufacturing and development is much faster than the speed of mold cleaning, and after the mold is quickly cleaned, it will be ready for the next production immediately, so the time left for mold cleaning is quite limited. How to clean the mold?

Standardized cleaning procedures

Systematic mold maintenance is based on maintenance requirements and the continuity of maintenance operations. In order to achieve the goal of "cost-effectiveness", cleaning molds must pay attention: develop a detailed mold cleaning plan. When cleaning different parts of the mold, such as the internal cleaning of the press, edge wiping, regular cleaning, and main part cleaning, the cleaning operation methods used are also different.

After the mold runs for a certain period of time and undergoes appearance tests such as electroplating wear, magnetic track marking, and mold residue content in vents and non-vent areas, technicians can determine the procedure and frequency of mold cleaning through visual inspection. Therefore, it is very important to understand the cycle of safe operation of the mold and to archive the observation report of the accumulation of residue and wear inside the mold.

Based on the mold has a certain operating cycle, all molds should be accompanied by related maintenance procedures and maintenance cycle documents. Generally, controlling the internal grease level and the operating conditions of gear broaching, sliding blocks, internal shaft pins and bushings, and other moving parts are the keys to ensuring stable production. Other factors affecting production include contamination or blockage of water lines and sprinkler outlets, leakage of manifolds, rust and corrosion due to water leakage or condensation.
