How to properly maintain the precision plastic mold?
Publish Time: 2024-10-09
Precision plastic mold plays a key role in the production of products such as car door locks. Proper maintenance can extend its service life and ensure production quality.
First of all, a comprehensive inspection should be carried out before each use of the mold. Check whether the various parts of the mold are complete and whether there is any damage or deformation. Especially for key molding parts, such as cavities and cores, ensure that their surfaces are smooth, without scratches and wear. At the same time, check whether the cooling system of the mold is unobstructed to prevent damage to the mold due to overheating caused by poor cooling.
During use, pay attention to operating specifications. Avoid using excessive clamping force to avoid excessive pressure on the mold. Control the injection temperature and pressure within a reasonable range to prevent excessive temperature and pressure from damaging the mold. At the same time, regularly clean the residue and oil on the surface of the mold to keep the mold clean.
After the mold is used, it should be maintained in time. First, clean the residual plastic in the mold. You can use special mold cleaning agents and tools to clean it. Then perform anti-rust treatment on the mold and apply an appropriate amount of anti-rust oil to prevent the mold from rusting. For moving parts, such as sliders and ejectors, add an appropriate amount of lubricating oil to ensure smooth movement.
When storing molds, choose a dry and well-ventilated place to prevent the molds from getting damp and rusting. Place the molds on a dedicated mold rack to avoid stacking and deformation. At the same time, check the stored molds regularly and deal with problems in a timely manner.
In addition, a complete mold maintenance record should be established. Record the number of times the mold is used, the maintenance status, the maintenance time and other information, so as to grasp the status of the mold in time and arrange the maintenance plan reasonably.
In short, the correct maintenance of Precision plastic molds needs to start from each link before, during, after and storage, and strictly follow the specifications to ensure the performance and service life of the mold, and provide reliable guarantee for the production of products such as car door locks.
