Several elements of safety protection of mold protection system of injection molding machine

    As the main consumption tool of injection molding factory, it determines the shape, specification, size, appearance and brightness of products. The data of hardware mold is steel, which is generally composed of front mold / rear mold.

    Mold maintenance

    Because the mold has the characteristics of focus, fineness, vulnerability and so on, it is very important to stop the safe maintenance of the mold. It can be summarized in the following aspects:

    1. Rust prevention: avoid rust caused by water leakage / condensate / rain / fingerprints of injection molding machine molds.

    2. Anti collision: avoid the mold damage caused by the breakage of the thimble and failure to return in place.

    3. Deburring: avoid mold burr caused by cloth wiping / material punching / hand wiping / nozzle clamp touching / knife touching.

    4. Missing parts: avoid the damage of the die during the application of the die due to the lack of pull rod / washer and other parts.

    5. Pressure prevention: avoid die crushing caused by die locking due to residual products.

    6. Undervoltage: avoid damage caused by excessive low pressure maintenance pressure of the die.

    Among them, the proportion of mold damage caused by thimble fracture, thimble failure to return in place, mold residual products and short accessories is high, and the occurrence is more frequent, so more than 85% of mold damage is caused by this reason, and the maintenance cost of mold is generally high. Therefore, how to prevent the occurrence of such conditions is directly related to the interests of the injection molding industry.

    In order to avoid the consumption delay caused by mold damage and high maintenance costs, and to better save human resources, ANQI technology has developed a product called "mold maintainer" by using machine vision technology after constant discussion and improvement.

    Mold monitor, or mold maintainer, also known as mold electronic eye, can effectively maintain expensive molds. The mold maintenance system of injection molding machine is installed on the injection molding machine, which can directly check whether the products are qualified, and check whether there are residues before mold closing, so as to avoid mold clamping damage. During the operation of the injection molding machine, the expensive mold may be damaged due to plastic residue or slider dislocation in each cycle. Anqi will automatically avoid closing the mold and alarm in case of abnormal occurrence.

    In case of mold damage due to failure to take effective mold maintenance, it is suggested that:

    Precautions for mold maintenance:

    1. When disassembling the mold, avoid bumping and drenching, and move it stably.

    2. Spray anti rust agent and a small amount of release agent.

    3. Stop the overall inspection of the mold and stop the antirust treatment: be careful to wipe the moisture and sundries in the cavity, core, ejector and row position, and spray the mold antirust agent and grease.

    Mold care

    In the continuous working process of the mold, due to the wear of parts, the degeneration of smoothing agent, water leakage, the crushing of plastic materials and other problems, it is necessary to stop the maintenance of the mold. Mold maintenance is generally divided into daily maintenance and lower mold maintenance

    The daily maintenance of molds generally includes the following aspects:

    1. Regularly remove rust (appearance, PL surface, mold cavity, core, etc.), and regularly clear sundries on parting surface;

    2. Regularly refill the smoothing agent (ejection mechanism, row position, etc.)

    3. Replace easily worn parts (tie rods, bolts, etc.) regularly

    4. Other areas needing attention
