How to prolong the service life of injection mold?

Injection mould is the main tool of manufacturing rubber and plastic products, because of its ELieXing office environment, it must accept multiple discipline, working pressure and temperature of injection mold moderate and proper maintenance can extend the service life of injection mold, reduce product cost, at the same time also can improve the work efficiency. So what maintenance secrets can prolong the life of injection mold?

1) Maintenance of injection mold in the whole process of injection production

① In the whole process of injection molding production, melting raw materials are formed in the injection mold according to the injection port through a certain working pressure. Therefore, injection molds can bear a lot of injection pressure. Therefore, proper and effective adjustment of injection pressure, injection rate, clamping force and reasonable spacing of supporting rod can reduce the damage of injection mold.

② In the application of injection mold, the temperature of injection mold must be controlled effectively and properly. At the same time, the application of injection mold must be observed at all times. If any abnormal phenomenon is found, it must be shut down immediately and check the problem.

③ Before the injection mold locking, we should pay attention to check whether there are foreign bodies in the cavity of the injection mold is not taken out, especially in whether there are residual products are not taken out, if there should be immediately removed, to prevent the harm of the locking, and even the destruction of the shell.

Two, the maintenance of injection mold production after manufacturing

① After injection molding, the shell should be closed to prevent wet and cold gas from contacting the cavity and core and causing corrosion. Can also be sprayed in the core and cavity of the anti-rust agent or film removal agent, to avoid long-term use of the injection mold and rust. However, it should be noted that chemical substances such as rust inhibitors should be scrubbed clean when applied again to prevent other problems. In addition, the cavity and core must be regularly removed to prevent erosion of residual products.

② If the injection mold is not used for a long time, the remaining water in the cooling circulation waterway should be eliminated immediately to prevent rust of the cooling circulation waterway.
