Solutions to common problems in aluminum die casting mold processing

1. Regarding the cleaning problem of the die-casting mold itself, clean the cavity and the top separately by layered cleaning to avoid the inclusion of impurities in the process, strengthen the ability of clamping the mold and the necessary spraying technology, and strengthen the weight of the cast metal. These are the actual operating methods that need to be performed during the operation, and they are also very easy to do; 2. Adjust the technical parameters, pay attention to the injection speed, capacity and filling time of the die-casting mold. The time to open the mold, as well as the temperature of the mold, to achieve these details, the quality must be no problem; 3. High-quality selection of materials, the use of high-quality aluminum alloy materials to improve the processing skills of smelting; 4. Renovate the interior of the die-casting mold, such as the discharge system, pouring system, etc.

1. If the die casting products appear black and flow marks, the pouring temperature and mold temperature should be appropriately increased; 2. If the alloy composition does not meet the standard, the alloy composition should be changed to improve fluidity; 3. See the flow direction of the molten aluminum when the mold is hot. The cold partition caused by the collision of the molten metal appears vortex-like with flow marks. The gating system should be improved to improve the filling direction of the inner gate. In addition, a slag bag can be set up at the edge of the casting to improve the filling conditions; 4. If the distal end is not compacted, the gate position and cross-sectional area should be changed to improve the overflow conditions and increase the overflow flow; 5. The product is dark and often accompanied by surface bubbles, so the injection speed must be increased correctly; 6. The overall pressure of the casting is not compact, and the injection pressure is relatively low, so the specific pressure should be increased appropriately.

1. Be sure to remember to clean after use to prevent falling off and metal materials. Long-term placement on the die-casting mold will affect its performance; 2. For the use of anti-oxidants, it is recommended to apply directly to larger mold parts, and to soak smaller precision parts. When using special materials, do not apply soaking if oxidants are not suitable for use, so as not to backfire; anti-oxidants can only prevent Its oxidation is not a panacea, so pay more attention when using it;
