When using a blow molding machine, the mold of the blow molding machine will inevitably have some failures. The mold of the blow molding machine is the core component, and we need to maintain the mold of the blow molding machine frequently; the maintenance of the mold of the blow molding machine requires a professionally trained engineer. Familiar with the technical standards of blow molding mold maintenance, here we share seven blow molding machine mold maintenance methods.

1. Sliding parts should be thoroughly cleaned, inspected and maintained. Such as core pulling mechanism and guiding device. Re-lubricate with high-temperature grease and assemble.

2. If there is a hydraulic core stack, the maintenance of the blow mold should be carried out at the same time as the hydraulic components. Special attention should be paid to cleaning during hydraulic maintenance; prevent contamination, otherwise it will contaminate the entire hydraulic system.

3. When the mold fails or is damaged in the production process, the maintenance plan of the blow mold should be determined according to the specific situation.

4. After repairing the mold, the molding surface, parting surface and mounting surface must be treated with rust prevention. The mold parts and the blow mold are placed together and marked to avoid confusion.

5. Clean the metal shavings in the blow mold and remove the oxide scale.

6. According to the final blow-molded product produced by the blow mold, determine whether it needs to be repaired. Check the blow mold carefully. Is there a strain or mold? Is the core bent or broken? Whether the movable core is inserted and positioned incorrectly. Whether the length of the push rod is changed or the push rod is broken, whether the positioning of the insert is incorrect, whether the fastening bolt is loose, etc. Define maintenance or replacement based on damage.

7. The internal cavity of the mold collapses, cracks, and the falling of the block will cause slight deformation, which can be repaired by partial welding. Welding maintenance should be carried out in strict accordance with the welding maintenance process. Otherwise, the life of the blow mold will be greatly shortened. The above failures occur on smaller molded parts. If the damage of the parts becomes more serious, it may cause damage to the mold.

Automatic blow molding machine

       In order to save costs, many manufacturers do not have their own professional mold department. Improper maintenance of molds by themselves will be prone to mold and other problems. In this way, it will be difficult to ensure the quality of the blow mold. Once there is a problem with the mold, the blow mold can only spend a lot of money to find the mold manufacturer for maintenance and repair, and it may affect the future use, which will lead to greater losses. Molds play an important role in blow molding machines and blow molding technology. In addition to the performance of the hollow blow molding machine, the performance of the blow mold directly affects the quality of the blow molded product. Therefore, Kaisu Machinery reminds you that in the maintenance of blow molds, we must comprehensively consider and adopt highly professional maintenance methods. Remember not to pick up the sesame seeds and lose the watermelon.
