Because the mold has characteristics such as specificity, precision, and vulnerability, the safety protection of the mold is very important. The overall summary is as follows:
- Anti-rust
Prevent injection molding machine molds from rusting caused by water leakage/condensation/rain/fingerprints, etc.
- Anti-collision
Prevent the mold from being damaged due to the breakage of the ejector pin and failure to return to the correct position.
- Remove thorns
Prevent mold burrs caused by cloth wiping/material punching/hand wiping/nozzle pliers/knife collision.
- Missing parts
Prevent mold damage during use due to lack of tie rods/washers and other parts.
- Anti-pressure
Prevent mold crushing caused by mold locking due to product still remaining.
6.Under voltage
Prevent mold damage caused by excessive low-pressure protection pressure.
Among them, the proportion of mold damage caused by the breakage of the ejector pin, failure of the ejector pin to return to the position, product residue in the mold, and lack of auxiliary parts is relatively high, and due to the occurrence of relatively
Frequent, so more than 85% of mold damage is caused by this reason, and the maintenance cost of molds is generally high, so how to avoid such situations is directly related to the interests of the injection molding industry.
Mold maintenance precautions
- When disassembling the mold, avoid being bruised and splashed with water, and the movement should be smooth.
- Spray the hot mold and then spray a small amount of release agent
- Conduct a comprehensive inspection of the mold and carry out anti-rust treatment: carefully wipe away the moisture and debris in the cavity, core, ejection mechanism and row position, etc.
And spray mold anti-rust agent and apply butter
