For the service life of the mold, we should pay attention to regular maintenance. First of all, the administrator of the die casting mold must always supervise and maintain the mold condition, pay attention to more management details, and make maintenance records for future inquiry; Secondly, the storage of the die casting die shall ensure the consistency of the account, drawings, documents, etc. The die cannot be kept separately to avoid the loss of parts. The zinc alloy die casting die that has not been used for a long time shall be subject to anti rust treatment regularly. The new die shall be stress relieved as much as possible during the specified period to prolong its service life.

In addition, aluminum, zinc and magnesium die casting dies are generally inspected according to regulations before leaving the factory. Only products that meet the standards can be put on the market. The specific standards are as follows:

1. The test methods, inspection standards and re inspection of the chemical composition of aluminum, zinc and magnesium die casting dies must comply with the relevant standards; The chemical composition of the sample product is traditional die-casting, and the mechanical properties, inspection methods, inspection times and inspection specifications in the mechanical properties must meet the requirements.

2. For products applicable to aluminum, zinc and magnesium die-casting mold samples, the size of parts, inspection and test mode must be determined after the technical meeting.

3. The geometric form of die casting inspection and test can be used to extract samples in a large range, or use relevant standards for inspection and test. The inspection and test results must conform to the specifications.

4. The factory inspection of the appearance quality of aluminum, zinc and magnesium die casting dies must be carried out one by one, and the inspection results must meet the standards.

5. The appearance roughness of aluminum, zinc and magnesium die casting dies shall comply with the standard.
