Automotive molds play a vital role in the automotive manufacturing industry, directly affecting the quality of parts, production efficiency and cost control. In order to ensure the efficient operation of the mold and extend its service life, regular maintenance and inspection are indispensable.

Mold appearance inspection
The appearance inspection of the mold is a basic part of the maintenance procedure. Regularly inspect the mold surface, focusing on whether there are obvious scratches, dents, rust or other damage. These appearance defects may have a negative impact on the molding effect of the mold, resulting in a decrease in the quality of the final product. During the inspection process, every detail of the mold should be carefully observed, especially those parts that are prone to dirt accumulation, such as cooling channels and exhaust holes.

Accuracy inspection
The accuracy of the mold is a key factor in ensuring that the size and shape of the finished product meet the design requirements. Regularly check the key dimensions of the mold, including the opening and closing gap, the matching accuracy of the locating pins, and the wear of the guide pins and guide sleeves. Be sure to use professional measuring tools, such as micrometers, calipers and three-dimensional coordinate measuring machines, to ensure that the working accuracy of the mold is always within the allowable range. Failure to meet the accuracy standard may lead to inconsistencies in the production process, which in turn affects the quality of the entire vehicle.

Matching parts inspection
The mold contains many matching parts, such as guide pins, guide sleeves and locating pins. The degree of wear of these parts directly affects the overall performance of the mold. Therefore, it is very important to regularly check the wear and matching accuracy of these matching parts. If some parts are found to be severely worn, they should be replaced or repaired in time to ensure the normal operation of the mold. This can not only improve production efficiency, but also reduce downtime caused by mold failure.

Cooling system detection
During the operation of the mold, the heat generated needs to be effectively dissipated through the cooling system to prevent the mold from being deformed or damaged due to overheating. Therefore, the normal operation of the cooling system is crucial. Regularly check the smoothness of the cooling channel to ensure that the flow of the coolant is not obstructed. In addition, the quality of the coolant needs to be tested to ensure that it is not contaminated or aged. Through the effective maintenance of the cooling system, the service life and production efficiency of the mold can be significantly improved.

Lubrication system detection
The good operation of the lubrication system can significantly reduce the friction between the mold parts and reduce the wear rate. Regularly check the quality and quantity of the lubricating oil to ensure that the lubricating oil is not contaminated and maintained at a reasonable level. For lubricants that need to be replaced regularly, be sure to replace them according to the manufacturer's recommendations and ensure that all parts of the lubrication system are functioning properly. Good lubrication maintenance can not only extend the service life of the mold, but also improve the stability and reliability of production.
