How to maintain precision casting parts

1. The punching needle is very easy to break, bend, and bite in the whole process of high-temperature alloy Precision Casting, and the punching mask is generally bitten. Damaged punch and sleeve specifications are generally replaced with parts of the same size. The basic parameters of the punching needle include the specification of the working part, the specification of the assembly part, and the length specification.

2. Tighten the parts. Check for loose or damaged tightening parts. The method of application is to replace the parts of the same size.

3. When repairing Aluminum Casting molds with force-bearing parts such as clamping plates, superior force plates, pouring plates, and pneumatic ejectors, check the relationship between the various parts of the precision casting complete set of equipment and whether they are damaged or repair the damaged part. Whether there is leakage of gas bottle stopper, and take certain effective measures according to the details. If the bronchus is damaged, replace it. Several key parts of the aluminum Casting Mold should be checked: ejection and guiding parts are used to determine the opening and closing of the mold and the ejection of plastic parts. If other parts of the mold get stuck due to damage, it will cause the production to stop. Therefore, the mold ejector should be maintained frequently. After one production cycle, the stainless steel precision-cast countertops, watch movements and guides are coated with a rust inhibitor. Care should be taken to maintain the ductile compressive strength of the rolling bearing components of the drive gear, worm dies and torsion spring dies to ensure that they remain in operation throughout.

4. The knife edge of the aluminum casting mold is sharpened for a long time, and the knife edge surface is demagnetized after cutting. It is not allowed to add magnetism, otherwise it will easily lead to blockage. Mold customer enterprises must complete records, statistical analysis of their application, maintenance (lubrication, cleaning, anti-rust treatment) and damage status, and based on what parts are damaged and damaged to find and solve information content. The technical parameters of the finalized processing technology of its aluminum casting mold and the raw materials commonly used in the product can reduce the trial operation time of the mold and improve the manufacturing rate.

5. The ductile parts such as the torsion spring of the aluminum casting mold are very easy to be damaged during the whole process of application, and usually break and deform. The approach is to change. When replacing the aluminum casting mold, pay attention to the model specification of the torsion spring. The model and specifications of the torsion spring are determined by three factors: color tone, diameter, and length, and only three of them can be changed.
