Let's go on to discuss the maintenance of injection molds
6. If the cavity surface has special requirements, and the surface roughness Ra is less than or equal to 0.2cm, absolutely can not be wiped by hand or cotton, It should apply compressed air, or use advanced napkins and high-grade cotton wool to gently rub the alcohol Wipe.
7. The surface of the cavity should be cleaned regularly. The injection mold will decompose the low molecular compound to corrode the mold cavity during the molding process, so that the surface of the bright cavity gradually becomes dull and reduces the quality of the product, so it needs to be scrubbed regularly. Scrub can be dried in time after scrubbing with alcohol or ketone preparations.
8. When the operation needs to be temporarily stopped, the mold should be closed to prevent the cavity and core from being exposed to prevent accidental damage. The downtime is expected to exceed 24 hours. It should spray the anti-rust oil on the surface of the cavity and core or mold release agents, especially in wet areas and rainy seasons, the time is short and also need to be rust-proof.
The moisture in the air will reduce the surface quality of the cavity and the surface quality of the product will decrease. When the mold is used again, the oil on the mold should be removed and wiped clean before use. The cleaned compressed air required by the mirror surface is dried and then dried with hot air, otherwise it will ooze out during molding and cause defects in the product.

9. After the temporary shutdown, when opening the mold, check whether the slider limit is moved. If no abnormality is found, the mold can be closed. In short, be careful before starting the machine, don't be careless.

10. In order to extend the lifetime of the cooling channel, the compressed water should be used to remove the water in the cooling channel immediately after the mold is deactivated. Use a small amount of oil to put into the mouth of the nozzle, and then blow it with compressed air to make all the cooling pipes have a oil layer. 
11. If you hear abnormal sounds or other abnormalities in the production, you should immediately stop and make inspection. The mold maintenance personnel shall conduct a patrol inspection on the normal running molds in the workshop, and when there are abnormal phenomena, they shall be dealt with in time.
12. When the operator is in the handover class, in addition to handing over the production, the use of the mold also must be detailed handover.
13. A mold warehouse should be set up with special personnel to manage, The mold warehouse should choose a place with low moisture and ventilation. The temperature should be kept below 70%. If the humidity exceeds 70%, the mold will be easy to rust. The mold should be stored on the shelf, pay attention to anti-corrosion and dustproof. Mark the signs that need to be repaired or repaired and maintained.
