Blowing mold maintenance procedures

1. Purpose: To maintain the best performance and extend the service life of the equipment to ensure the normal production.

2. Scope of application: suitable for mold repair and maintenance.

three. Regular inspection and maintenance: It is necessary to carry out regular maintenance and inspection by mold repair, upper and lower mold personnel.

1. Daily routine inspection and maintenance:

1.1 Is the mold in operation in a normal state?

a. Whether there is low voltage mode locking protection;

b. Are the movable parts such as guide posts, ejector rods, and rows worn out, and are they well lubricated? It is required to refuel at least 12 hours, and the special structure needs to increase the refueling frequency.

c. Whether the screws and code clamps of the fixed template of the mold are loose;

1.2 Normal production conditions: check whether the defects of the product are related to the mold;

1.3 The mold should be inspected comprehensively and anti-rust treatment should be carried out when the machine is off: Wipe dry the moisture in the cavity, core, ejector mechanism and row position and spray the mold anti-rust agent or apply butter.

1.4 The mold after the machine should be placed in the designated place and recorded: (1) Mold condition: in good condition or to be repaired. (2) Anti-rust treatment method for lower mold.

2. Routine inspections every season:

It is mainly to clean and maintain molds that have not been used for more than two months.

2.1 Open the mold and check the internal anti-rust effect. If there is any abnormality, the anti-rust treatment must be performed again. The mold that has not been used for a long time must be coated with butter.

2.2 Put it back in place and make a record.

four. Maintenance notes:

1. Non-professional maintenance personnel or without the permission of professional maintenance personnel are not allowed to disassemble the mold for maintenance.

2 Minor faults in the production process can be solved by the commissioning personnel according to the situation. Such as: 2.1 Nozzle sticking mold:

Use a copper needle to knock out at the feed nozzle. Do not knock the mold with hard objects such as steel needles. 2.2 There are slight mold marks in the cavity. The polishing material can be selected according to the finish of the cavity. Polishing materials such as sandpaper should not be used on the textured surface. Generally, copper brush dipped in diamond paste or diamond mortar should be used to clean it by professional maintenance personnel. 2.3 Product sticking: generally use hot plastic to cover the product and ejection part, and eject after cooling. Be careful not to damage the surface of the mold if it is burned with fire.

3. When the professional is repairing the mold, the structure cannot be changed at will, and the change of the structure must be approved by the quality engineering department.

4. Ensure the quality of maintenance, select appropriate equipment, materials, tools and methods to solve the problem, and complete it as quickly as possible.

Fives. Keep quality inspection records.
