What are the tips for the daily maintenance and management of injection molds?

Injection mold is an important production tool for the production of plastic products, and its performance directly affects product quality and production efficiency. In order to ensure the normal service life and production efficiency of injection molds, it is necessary to pay attention to daily maintenance and management. The following will introduce the daily maintenance and management of injection mold tips for reference.

1. Preparation before use

1, clean the mold: before use, be sure to clean the mold, especially in the storage process, the surface of the mold may produce oil and oxide, these dirt is easy to affect the use of the mold.

2. Check before clamping: Before clamping the injection mold, check whether the connection of each part of the mold is firm, whether the gauge size is appropriate, whether the connection between the fixed rod and the mold bottom plate is firm, to ensure the safety and stability of the mold.

3, lubrication mold: the common lubricants for mold processing materials are liquid paraffin oil, mineral oil, high temperature lubricating oil, etc., to ensure adequate lubrication before use, so as to avoid sticking or other failures during the use of the mold.

Second, the use of precautions

1, temperature stability: After the plastic is injected into the mold and heated, it will shrink or expand because of the change in temperature, overheating will lead to deformation, and undercooling will affect the quality of injection molding. Therefore, the injection mold must maintain the stability of the temperature, and regularly check the cooling water and electric heating to avoid uneven heating of the mold.

2, the injection cycle control: the injection cycle includes the mold in and out of the material time, injection time, cooling time, etc. The choice of these times should be reasonable according to the nature of the plastic and the injection verticality, in the use of the mold need to pay attention to check and adjust.

3, regular testing: In the use of injection molds, it is necessary to carry out regular testing, such as the flatness of the mold, the incision, etc., and timely repair or replacement of the damaged part to ensure the stable use of injection molds.

Three, injection mold maintenance

1. Storage location: During the use of the injection mold, it should be prevented from being stimulated by high temperature, high humidity, dust and so on for a long time, and should be placed in a dry, ventilated and dust-free place.

2, to prevent rust: injection molds contain metal materials, long-term storage is easy to produce rust, should be regularly used to maintain the mold to ensure that the mold surface clean and smooth.

3, the service cycle: injection mold in use for a certain period of time, due to various factors and parts of the damage and fatigue, it is recommended that periodic inspection and maintenance, timely replacement or reinforcement of damaged parts, in order to extend the service life of the injection mold.

4, pay attention to anti-corrosion: for different materials of the mold, the use of different anti-corrosion measures, such as surface chromium plating, hard chromium plating, spraying PVD, nitriding, etc., to improve the corrosion resistance of the mold.

To sum up, the daily maintenance and management of injection molds is a very important part of injection molding production, which can not only extend the service life of injection molds, but also improve product quality and production efficiency. Therefore, in injection molding production, we should pay attention to the details and maintain the injection mold, which is crucial to ensure the quality and efficiency of injection molding production.
