Daily Maintenance And Molds Safety Protection

As the most important production tool of a die-casting factory, it determines the shape, specification, size, and appearance finish of the product. The material of the mold is steel, which is generally composed of a front mold/rear mold.

Mold protection

Due to the specificity, precision, and fragility of the mold, the safety protection of the mold is very important. The overall summary is as follows:

1. Anti-rust: Prevent rusting caused by water leakage/condensed water/rain/fingerprints in the mold of the injection molding machine.
2. Anti-collision: Prevent the mold from crashing due to the breakage of the thimble and the failure to retract into place.
3. Deburring: Prevent mold burrs caused by cloth wiping, material punching, hand wiping, nozzle pliers touch, and knife touch.
4. Missing parts: prevent mold damage during use due to lack of tie rods/washers and other parts.
5. Anti-pressure: Prevent the mold from being crushed due to the mold being locked due to the remaining product.
6. Under-pressure: to prevent mold damage caused by excessive low-pressure protection pressure.

Among them, the proportion of mold damage caused by the thimble broken, the thimble has not returned in place, the mold remains product, and the lack of accessories are relatively high, and because it occurs more frequently, more than 85% of the mold damage is caused by this reason. The maintenance costs of molds are generally high, so how to avoid such situations is directly related to the interests of the injection molding industry.

In order to prevent production delays caused by mold damage and high maintenance costs, as well as to better save labor resources, Anqi Technology has developed a product called "mold" through continuous research and improvement using machine vision technology. protector".

Anqi mold monitor, or mold protector, also known as mold electronic eye, can effectively protect valuable molds. Anqi ® injection molding machine mold protection system, installed on the injection molding machine, can directly check whether the product is qualified, and check whether there is any residue before closing the mold to prevent the mold from pinching. When the injection molding machine is running, in each cycle, expensive molds may be damaged due to plastic residues or dislocation of the slider. Anqi prevents these situations from happening, and automatically prevents the mold from closing and alarms when an abnormality occurs.

If the mold is damaged due to failure to take effective mold protection, we will give you the following suggestions:

Precautions for mold maintenance

1. When disassembling the mold, avoid bumps and splashing water, and move smoothly.
2. Spray the hot mold, and then spray a small amount of release agent
3. Perform a comprehensive inspection of the mold and perform anti-rust treatment: carefully wipe dry the moisture and debris in the cavity, core, ejector mechanism, and row position, and spray the mold anti-rust agent and apply butter.

Mold Maintenance

In the continuous working process of the mold, due to the wear of the parts, deterioration of the lubricant, water leakage, and crushing of the plastic material during the movement process, the mold needs to be maintained.

Mold maintenance is generally divided into daily maintenance and lower mold maintenance

The daily maintenance of the mold generally includes the following aspects:

1. Regularly remove rust (appearance, PL surface, mold cavity, core, etc.)
2. Regularly re-add lubricant (ejector mechanism, row position, etc.)
3. Regular replacement of wear parts (tie rods, bolts, etc.)
4. Other things to pay attention to

The lower mold maintenance of the mold requires professional maintenance personnel to remove the mold, and then conduct professional testing and protection of the mold cavity and thimble.
