Die casting molds are expensive to manufacture due to the complex and harsh production environment. Therefore, it is required that the maintenance and repair of die-casting molds not only have exquisite technology and meticulous work style, but also have a serious and responsible spirit.
If you want to use die-casting molds for a long time, maintenance and upkeep these 10 points must be achieved! Here's to share with everyone:
1. Before mold maintenance and repair, the last die-cast product must be retained.
2. Thoroughly clean all metal shavings and deposits on the mold, clean and clean the mold, and restore its original color.
3. Check the final die-cast product for any scratches, mold sticking, crushing, peeling, as well as changes in size and hole position.

4. Comprehensive inspection of the mold: whether there are small cores bent or broken, whether there are movable cores inserted and positioned incorrectly, whether there are broken push rods or changes in the length of push rods, whether there are insert blocks positioned incorrectly, and whether there are loose fastening bolts. Determine repair or replacement based on the damage situation.
5. Local welding repair should be carried out for cavities that cause slight strain on castings, such as collapse, cracks, and falling blocks. Welding repair should be strictly carried out in accordance with the specified process.
6. Sliding parts such as core pulling mechanisms and guiding devices should be thoroughly cleaned, carefully inspected, and repaired. Relubricate with high-temperature grease before assembly.
7. If there is hydraulic core pulling, the hydraulic part and the mold should be repaired simultaneously. Pay special attention to cleanliness during the maintenance of the hydraulic part to prevent contamination, otherwise it may contaminate the entire hydraulic system of the die-casting machine.
8. When the mold malfunctions or is damaged during the production process, the repair plan should be determined according to the specific situation. The mold must have corresponding maintenance and repair plans in place.
9. After completing the maintenance and repair of the mold, the entire set of molds, including the forming surface, parting surface, and installation surface, should be treated with rust prevention. After the mold is correctly assembled, it should be placed in the planned area with proper identification, and the mold accessories must be placed together with the mold.
10. A certain number of molds should be produced after annealing treatment, followed by corresponding heat treatment and surface treatment.
