As the most important production tool for injection molding plants, it determines the shape, size, size and appearance of the product. The material of the metal mold is steel, which is generally composed of a front mold/a rear mold.
Mold protection
Because the mold has the characteristics of specific precision and vulnerability, it is very important to carry out the safety protection of the mold. The general summary is as follows:
1. Anti-rust: Prevents the rust of the injection molding machine mold from water leakage/condensation/rain/handprint.
2. Anti-collision: Prevents the mold from colliding due to the thimble breaking or not falling back into position.
3. In addition to the thorn: prevent the mold from being smashed by the cloth/material punch/hand wipe/water jaw clamp/knife touch.
4. Missing parts: 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-pressure: Prevent mold damage caused by mold clamping due to residual mold remaining.
6. Under-pressure: Prevent the damage caused by the mold due to excessive pressure protection.
Among them, more than 85% of the mold damage is caused by the fact that the thimble is broken, the thimble is not retracted, the mold remains in the product, and the lack of accessories causes a high degree of mold damage. The maintenance cost of the mold is generally high, so how to avoid such a situation is directly related to the interests of the injection molding industry.
In order to prevent production delay caused by mold damage, as well as high maintenance costs, and to save labor resources, Anzhen Technology has developed a product called machine mold through continuous research and improvement. protector".
Mold monitors, or mold protectors, also known as mold electronic eyes, can effectively protect expensive molds. Mold expert Luo Baihui said that the injection molding machine mold protection system, installed on the injection molding machine, can directly check whether the product is qualified, and check for residue before clamping to prevent mold damage. When the injection molding machine is running, expensive molds may be damaged due to plastic residue or slider misalignment in each cycle. Ampoules prevent these from happening and automatically prevent mold closing and alarm when an abnormality occurs.
If the mold is damaged because of the lack of effective mold protection, we will give you the following suggestions:
Mold repair notes:
1. When disassembling the mold, avoid bumps and water spray, and move smoothly.
2. Spray hot mold, then spray a small amount of release agent
3. The mold should be thoroughly inspected and rust-proofed: carefully dry the cavity, core, ejection mechanism and line of water and debris, and spray mold rust inhibitor and butter.
Mold maintenance
During the continuous working process of the mold, mold maintenance is required due to problems such as wear and tear of the parts during the movement, deterioration of the lubricant, water leakage, and crushing of the plastic material.
Mold maintenance is generally divided into daily maintenance and mold maintenance
Daily maintenance of molds generally includes the following aspects:
1. Regular rust removal (appearance, PL surface, cavity, core, etc.)
2. Regularly re-lubricating (ejection mechanism, row position, etc.)
3. Regularly replace wear parts (rods, bolts, etc.)
4. Other places to pay attention to
The maintenance of the lower mold of the mold requires professional maintenance personnel to remove the mold, and professionally test and protect the mold cavity and thimble of the mold.
