How To Maintain The Mold Of Glass Bottles

The maintenance of glass bottle molds is the key to ensure their long-term stable operation and extend their service life. Here are some specific maintenance methods and suggestions:

Cleaning up ash and oxidation plaques in time:
During the production process, glass bottle molds will produce ash and oxidation plaques after high temperature and mold release agent use. If these residues are not cleaned in time, they will cause great damage to the mold.
It is recommended to use water washing method for cleaning. Water washing molds use high-pressure gas to drive quartz sand and water flow to clean the mold. This method has less damage to the brightness and damage of the mold, and less wear.
Avoid using sandblasting cleaning:
Although sandblasting cleaning is also a cleaning method, it will cause greater damage to the mold. Sandblasting cleaning is to clean the mold by spraying quartz sand in the mold cavity with high-pressure gas, and then polishing with a grinder and applying butter to prevent rust. This method should be avoided as much as possible.

Storage environment:
When not in use, the mold should be stored in a well-ventilated environment with a relative humidity of less than 70% to prevent the mold from rusting.
Use of rust preventive:
When the mold stops using, the working parts and sliding parts should be treated with rust prevention in time. The most commonly used rust prevention method is to use rust preventive, that is, to evenly apply a layer of rust-proof oil or rust-proof grease on the surface of the mold.
Rust-proof oil is suitable for situations where the storage time is slightly shorter, while rust-proof grease is suitable for situations where the storage time is longer. If there is no suitable rust-proof oil or rust-proof grease, using ordinary engine oil or butter can also play a certain rust-proof role.
Preparation before rust prevention:
Before rust prevention, the debris, demoulding residues, dirt and oil left in the mold should be thoroughly removed to ensure that the mold surface is clean and free of impurities.

Lubrication of sliding parts:
The sliding parts of the mold should be regularly coated with an appropriate amount of lubricating oil to reduce wear and extend service life. However, the amount of lubricating oil should be moderate, and too much may overflow and contaminate the parts.
Tightening screws and parts:
Regularly check whether the screws and parts on the mold are loose or damaged, and tighten or replace them in time if necessary. For example, in the lateral core pulling mechanism of the inclined guide pin, the loosening of the screws fixing the inclined guide pin will cause the position of the inclined guide pin to change, or even deform or break, so it must be tightened in time.

Pre-shipment preparation:
The mold should be wiped clean before leaving the factory, and rust-proof agent should be applied to the surface of all parts or rust-proof packaging should be used. The movable and fixed molds should be packaged as a whole as much as possible. For parts that allow separate packaging, such as water nozzles, oil nozzles, hydraulic cylinders, cylinders, electrical parts, etc., sealing measures should be taken to prevent the entry of foreign objects.
Transportation requirements:
The mold should be moisture-proof and bump-proof during transportation to ensure that the mold is intact. The packaging box should be accompanied by relevant documents such as the certificate of conformity.

Timely maintenance:
The downtime and operating costs of the mold can be reduced through regular maintenance and timely repairs. For example, timely refueling can reduce the wear and failure rate of sliding parts.

Regular preventive maintenance can detect and solve potential problems in time and avoid major failures of the mold during production.
In summary, the maintenance of glass bottle molds requires comprehensive consideration of cleaning, rust prevention, regular inspection and maintenance, packaging and transportation, etc. Scientific and reasonable maintenance methods can effectively extend the service life of the mold and reduce production costs.
