Standard mold mold maintenance process and maintenance attention

Mold maintenance refers to the daily maintenance of the standard mold mold frame by the operator in the production, and the main content is cleaning, lubrication and inspection.

Maintenance during molding:

1. Clean the upper and lower surfaces of the mold before loading to ensure that the mold mounting surface and the working table of the press are not damaged by pressure and the parallelism of the upper and lower mounting surface of the mold in production;

2. After the mold is installed, the mold is opened, and all parts of the mold are cleaned, especially the guiding mechanism. For the surface part of the mold, the mold surface should be cleaned to ensure the quality of the parts;

3. Lubricate and grease each sliding part of the mold;

4. Check all parts of the mold, especially safety parts. Such as: safety side pins, safety screws, side protection plates, punching waste channels, etc.

Maintenance in production:

1. The corresponding part of the mold is oiled regularly during production. Such as: drawing die press ring, rounded corners; The cutting edge part of the trimming die; Flanging knife block part, etc.;

2. Clean the waste of the small hole waste path of the trimming and punching die regularly.

Maintenance after production:

1. A comprehensive inspection of the mold should be carried out after the end of production;

2. Comprehensively clean the mold to ensure the cleanliness of the mold;

3. Clean up the waste in the mold to ensure that there is no waste in the waste box;

4. Record the use status of the standard mold and the situation after use in detail on the resume card.

Maintenance precautions:

1. If there is a small fault in the production process, the personnel can solve it according to the situation. For example, the water sticking mold: Use a copper needle to knock out the mold at the feed nozzle. Do not knock the mold with a hard object such as a steel needle. The cavity is slightly moulded, and the polishing material can be selected according to the finish of the cavity. Abrasive paper and other polishing materials can not be used on the grain surface, generally with a copper brush dipped in diamond plaster or diamond mortar scrub, completed by professional maintenance personnel. Product sticking mold: Generally use hot plastic to cover the product and ejection parts, to be cooled after ejection. If using fire, be careful not to damage the mold surface.

2. Non-professional maintenance personnel or without the permission of professional maintenance personnel, can not dismantle the mold maintenance. When professional personnel repair mold, can not arbitrarily change the structure, need to change the structure must be approved by the quality engineering department can be carried out.

3. Ensure the quality of maintenance, select the appropriate equipment, materials, tools and problem-solving methods, and complete it at the fastest speed.
