Lubricating oil seal of the injection molding machine

The working principle of the lubricating oil seal of the injection molding machine

Lubricating oil seal of the injection molding machines mainly rely on seals and sealing structures to achieve. Seals are usually made of abrasion-resistant, high-temperature, and corrosion-resistant materials to ensure good sealing performance in harsh working environments. The sealing structure is reasonably designed so that the lubricating oil will not leak to the outside of the machine or penetrate into other parts inside the machine during the circulation process.

During the operation of the injection molding machine, the lubricating oil is driven by the oil pump and passes through the filter, cooler and other components to form a circulation loop with a certain pressure and flow. In this process, the seal and the seal structure work together to ensure that the lubricating oil remains sealed in the circulating circuit, thus lubricating and cooling the injection molding machine.

The key technology of lubricating oil seal of the injection molding machine

Selection of sealing materials

The sealing material should have excellent wear resistance, high temperature resistance and corrosion resistance to cope with the working environment of high temperature, high pressure and high speed of the injection molding machine. Common sealing materials include rubber, PTFE, metal, etc.

Sealing structure design

The design of the sealing structure should take into account the structural characteristics, working principle and operating environment of the injection molding machine. The reasonable sealing structure can effectively prevent the leakage and penetration of lubricating oil, and improve the operation stability and reliability of the injection molding machine.

Installation and debugging of seals

The installation of the seal should be carried out in strict accordance with the operating procedures to ensure that the installation position is accurate and the fastening force is moderate. After the installation is completed, it is also necessary to carry out commissioning and inspection to ensure that the sealing performance meets the requirements.

Maintenance Strategies for Lubricating Oil Seal of the Injection Molding Machines

Check it regularly

Regularly inspect the lubricating oil seals of the injection molding machine, including the wear of the seals, the integrity of the seal structure, and the cleanliness of the lubricating oil. If the problem is found, it will be dealt with in time to prevent the problem from expanding and affecting the normal operation of the machine.

Replace the seals

Over time, seals wear out, resulting in a decrease in sealing performance. As a result, heavily worn seals need to be replaced regularly to restore the sealing properties of the lubricating oil.

Cleaning and maintenance

Keep the injection molding machine and its surroundings clean to prevent contaminants such as dust and impurities from entering the lubricating oil system. Regularly clean and maintain the lubricating oil system to ensure the quality of the lubricating oil and the smooth circulation circuit.

Reasonable use of lubricating oil

Select the lubricating oil that meets the requirements of the injection molding machine and replace it according to the specified replacement interval. Avoid the use of substandard or expired lubricating oils to avoid damage to seals and seal structures.

Conclusione

The lubricating oil seal of the injection molding machine is the key link to ensure the stable operation of the machine. By understanding how lubricant seals work, key technologies, and maintenance strategies, we can better maintain and manage injection molding machines, improve production efficiency, and reduce maintenance costs. In practice, we should pay attention to the selection, installation and commissioning of seals, as well as regular inspection and maintenance of the lubricating oil system to ensure the long-term stable operation of the injection molding machine.

Here are some frequently asked questions (FAQs) about lubricating oil seal of the injection molding machine:

What is the main function of the lubricating oil seal of the injection molding machine?

The main function of the lubricating oil seal of the injection molding machine is to ensure that the lubricating oil maintains its due role in the lubrication system, and prevents the lubricating oil from leaking or external impurities from entering the lubrication system, so as to ensure the normal operation and prolong the service life of the injection molding machine.

How to tell if the lubricating oil seal of the injection molding machine is damaged?

If it is found that there is a leak in the lubricating oil of the injection molding machine, or the lubrication system is working abnormally (such as high oil temperature, unstable pressure, etc.), it may be a sign that the lubricating oil seal is damaged. In addition, abnormal sounds or vibrations when the machine is operating can also be a sign of a sealing problem.

What are the reasons for the damage of the lubricating oil seal of the injection molding machine?

Seal damage can be caused by aging sealing materials, wear, improper installation, contaminated or insufficient lubricating oil, high or low operating temperatures, etc.

How to prevent the lubricating oil seal damage of the injection molding machine?

Preventive measures include regular oil and seal replacement, ensuring that the oil is clean and free of contamination, controlling operating temperatures within appropriate ranges, and properly installing and maintaining seals.

How to replace the lubricating oil seal of the injection molding machine?

When replacing the seal, you need to turn off the injection molding machine and disconnect the power supply first, and then follow the manufacturer’s instructions or the guidance of a professional, remove the old seal and install the new one. Pay attention to keep it clean during installation to avoid impurities entering the lubrication system.

What kind of lubricating oil sealing material is better to choose?

When selecting a lubricating oil sealing material, the material’s wear resistance, temperature resistance, oil resistance, and compatibility with lubricating oil should be considered. In general, high-quality materials provide better sealing and longer service life.

How to maintain the lubricating oil seal of the injection molding machine to prolong its service life?

Regularly checking and changing the lubricating oil, keeping the lubrication system clean, and avoiding overloading the machine are all effective ways to extend the life of the lubricant seal. In addition, it is also very important to carry out regular professional maintenance to identify and solve problems in a timely manner.

Please note that these are just some of the most frequently asked questions and answers, and may vary depending on the model of the injection molding machine, the conditions of use, and the maintenance situation. Therefore, in practice, it is recommended to refer to the instruction manual of the injection molding machine or consult a professional technician.
