As the main production tool of injection molding factory<\/a><\/strong>, mold determines the shape, specification, size and appearance finish of products. The material of hardware mold is steel, which is generally composed of front mold \/ rear mold.<\/p>\n\n\n\n

Mold protection<\/p>\n\n\n\n

Because the mold has the characteristics of specificity, precision, vulnerability and so on, it is very important to protect the safety of the mold. Generally, it can be summarized in the following aspects:<\/p>\n\n\n\n

1. Rust prevention: prevent rust caused by water leakage \/ condensate \/ rain \/ fingerprints of injection molding machine molds.<\/p>\n\n\n\n

2. Anti collision: prevent the die from being damaged due to the breakage of the thimble and failure to return in place.<\/p>\n\n\n\n

3. Deburring: prevent mold burrs caused by cloth wiping \/ material punching \/ hand wiping \/ nozzle clamp collision \/ knife collision.<\/p>\n\n\n\n

4. Missing parts: prevent the mold from being damaged during the use of the mold due to the lack of pull rod \/ washer and other parts.<\/p>\n\n\n\n

5. Pressure prevention: to prevent die crushing caused by die locking due to residual products.<\/p>\n\n\n\n

Undervoltage: prevent mold damage caused by excessive low pressure protection pressure.<\/p>\n\n\n\n

Among them, the proportion of mold damage caused by thimble fracture, thimble failure to return in place, mold residual products and lack of accessories is high, and it occurs more frequently, so more than 85% of mold damage is caused by this reason, and the maintenance cost of mold is generally high. Therefore, how to avoid this kind of situation is directly related to the interests of the injection molding industry.<\/p>\n\n\n\n

Precautions for mold maintenance:<\/p>\n\n\n\n

1. When disassembling the mold, avoid bumping and drenching, and move stably.<\/p>\n\n\n\n

2. Spray anti rust agent and a small amount of release agent.<\/p>\n\n\n\n

The mold shall be comprehensively inspected and treated with rust prevention: carefully wipe the moisture and sundries in the cavity, core, ejector and row position, and spray the mold rust inhibitor and grease.<\/p>\n\n\n\n

Mold maintenance<\/p>\n\n\n\n

In the continuous working process of the mold, due to the wear of parts, deterioration of lubricant, water leakage, crushing of plastic materials and other problems, the mold needs to be maintained.<\/p>\n\n\n\n

The daily maintenance of molds generally includes the following aspects:<\/p>\n\n\n\n

1. Regularly remove rust (appearance, PL surface, mold cavity, core, etc.), and regularly clean sundries on the parting surface;<\/p>\n\n\n\n

2. Refill lubricant regularly (ejection mechanism, row position, etc.)<\/p>\n\n\n\n

3. Replace easily worn parts (pull rods, bolts, etc.) regularly<\/p>\n\n\n\n

4. Other points needing attention<\/p>\n\n\n\n
