Maintenance and upkeep methods for bottle cap molds

Today, injection mold products are widely used in daily life and production, and the demand for injection molds from manufacturers is also increasing. Therefore, the daily maintenance and upkeep of molds are very important. The manufacturer shares with you the methods of maintenance and upkeep of molds, hoping to be helpful to everyone!

Maintenance of bottle cap molds

During continuous operation, molds are prone to wear and tear of components, deterioration of lubricants, water leakage, and pressure damage to plastic materials due to their movement. Therefore, mold maintenance is necessary.

Daily maintenance of molds includes the following aspects:

1. Regular rust removal (appearance, PL surface, mold cavity, core, etc.)

2. Regularly refill lubricants (such as ejector mechanism, travel position, etc.)

3. Regularly replace easily worn parts (such as rods, bolts, etc.)

4. Other areas that need attention

The maintenance of the lower mold requires professional maintenance personnel to remove the mold and perform professional testing and protection on the mold cavity, ejector pin, etc.

Protection of bottle cap molds

Due to the specificity, precision, and vulnerability of molds, it is crucial to ensure their safety. Overall, there are several aspects to consider:

1. Rust prevention: To prevent rusting caused by water leakage, condensation, rain, fingerprints, etc. on injection molding machine molds.

2. Collision prevention: To prevent mold damage caused by broken or improperly retracted top pins.

3. Removal of burrs: Prevent mold burrs caused by cloth wiping/material punching/hand wiping/water mouth pliers collision/knife collision.

4. Missing parts: To prevent damage to the mold during use due to the lack of pull rods/washers and other components.

5. Pressure prevention: To prevent mold damage caused by mold locking due to residual products.

6. Undervoltage: To prevent damage to the mold caused by excessive low-pressure protection pressure.

The proportion of mold damage caused by broken top pins, incomplete retraction of top pins, residual products in molds, and lack of accessories is relatively high, and it occurs frequently. Therefore, more than 85% of mold damage is caused by this reason, and the maintenance cost of molds is generally high. Therefore, how to avoid such situations directly affects the interests of the injection molding industry.

Precautions for repairing bottle cap molds

When disassembling the mold, avoid collision and water splashing, and move it smoothly.

2. Spray the hot mold and then spray a small amount of release agent.

3. Conduct a comprehensive inspection of the mold and perform rust prevention treatment: carefully dry the moisture and debris in the mold cavity, core, ejection mechanism, and row position, and spray mold rust inhibitor and apply butter.
