1. For vulnerable parts, such as ejector rod and core, carefully check whether there are bends and cracks. If there are, replace them in time. In many cases, when the mold is reproduced, the core is broken without completing many mold times. Most of the reasons are that there is no careful inspection and problems are not found before, resulting in a great waste of manpower and time.
2. Repair and maintenance of zinc alloy die casting die should be polished wherever there is aluminum sticking and carbon deposition, so as to minimize the wear caused by polishing.
3. All moving parts, joint parts and screws of the die shall be lubricated and antirust treated.
4. The management personnel of die casting die shall supervise the maintenance status at any time, pay attention to other management details, and make maintenance records for future query.
5. The storage of molds shall be consistent with the accounts, drawings and archives. Molds cannot be disassembled for storage to avoid the loss of parts. Zinc alloy die casting molds that have not been used for a long time shall be subject to rust prevention treatment regularly. The new die shall be stress relieved as far as possible within the specified period to prolong its service life.

In the process of mold maintenance and repair, some words are very simple and understood, but it is difficult to do it. Therefore, we need to conscientiously implement the maintenance and repair of the above zinc alloy die casting mold and do the work in place.
