Foam Packaging Mold Maintenance


There are many types of molds for foam packaging production, high replacement frequency and high loss rate. It is necessary to regulate the maintenance and maintenance of the mold. The quality of the mold determines the shape, specifications, size and appearance of the product. The material of the mold is steel, which generally consists of a front mold / rear mold.
1. Mold protection Because the mold has the characteristics of specificity, precision, and fragility, it is very important to protect the safety of the mold. The following are summarized as follows:
1. Anti-rust: Prevent the mold from rusting due to water leakage / condensation / rain / handprint.
2. Anti-collision: prevent the mold from colliding due to the breakage of the thimble and failure to return.
3, thorn removal: to prevent mold burrs caused by cloth wiping / material punching / hand wiping / nozzle forceps / knife touch.
4. Missing parts: To prevent the mold from being damaged during the use of the mold due to the lack of parts such as tie rods / washers.
5. Anti-press: prevent mold from being locked due to product residue, which will cause mold injury.
6, under pressure: prevent the mold from being damaged due to excessive low pressure protection.
Among them, the proportion of the mold damage caused by the broken thimble, the thimble not returned in place, the product remaining in the mold, and the lack of auxiliary parts is higher. More than 85% of the mold damage is caused by this reason, and the maintenance cost of the mold is generally high. , So avoiding such situations is directly related to the effectiveness of the business.
Second, the mold maintenance precautions 1. When disassembling the mold, avoid bumps and move smoothly.
2. Spray the hot mold, and then spray a small amount of release agent. 3. Make a comprehensive inspection of the mold and perform rust prevention treatment. Carefully wipe the moisture and debris in the cavity, core, ejection mechanism and row position, and Spray mold rust inhibitor and butter.
Third, mold maintenance In the continuous working process of the mold, due to the wear and tear of parts and components during the movement process, lubricant deterioration, water leakage, crushing and other problems, mold maintenance is required.
The daily maintenance of the mold generally includes the following aspects:
1. Regular rust removal (appearance, PL surface, cavity, core, etc.)
2. Regularly re-lubricate (eject mechanism, row position, etc.)
3. Regularly replace wearing parts (rods, bolts, etc.)
4. Other places that need to pay attention to the maintenance of the lower mold of the mold should be professionally tested and protected by the professional maintenance personnel after the mold is removed.
