Analyze the casting mold, what kind of mold structure, arrange the product process, determine the content of each process, and use the design software to design the product. When designing a product, it usually starts with a subsequent process. Next, let's talk about the daily maintenance of casting molds:

1. The punch is easy to break, bend and bite during the use of the casting mold, and the punch sleeve is generally bitten. Damaged punches and sleeves are generally replaced with parts of the same specification. The parameters of the punch mainly include the size of the working part, the size of the installation part, the length dimension, etc.

2. Fastening parts. Inspect for loose or damaged fasteners. The method used is to replace parts of the same specification.

3. When repairing the casting mold of pressure parts such as pressure plate, upper force plate, discharge plate and pneumatic ejector, check the relationship between the parts and whether there is any damage, repair the damaged parts, check whether there is leakage of the gas cylinder cap and take measures according to the specific situation. If the trachea is damaged, replace it. Several important parts of the casting mold should be checked: the ejection and guiding parts are used to determine the opening and closing movement of the mold and the ejection of the plastic parts. If any part of the mold gets stuck due to damage, it will stop production. Therefore, the stripper should be maintained frequently. After completing a production cycle, the working surface of the casting mold, the movement and the guide rail are coated with anti-rust oil. Special attention should be paid to the elastic strength of the bearing parts of the gear, rack and spring die to ensure that they are always in working condition.

4. The cutting edge of the casting mold is sharpened for a long time, and the surface of the cutting edge is magnetized after grinding and cannot be magnetized, otherwise it is easy to cause blockage. The mold user company needs to record it in detail, count its use, maintenance (lubrication, cleaning, rust prevention) and damage, and provide discovery and resolution information based on which parts are damaged and worn. As well as the molding process parameters of the casting mold and the materials used in the product, it can shorten the trial operation time of the mold and increase the production speed.

5. The elastic parts such as the spring of the casting mold are easily damaged during use, and usually break and deform. The approach is to change. When replacing the casting mold, pay attention to the specifications and models of the spring. The specifications of the spring are determined by the color, outer diameter, and length. Only the three items can be changed.
