1, Mold design

2, Die material selection

The selection of mold materials directly affects the quality and service life of the mold. Therefore, when selecting mold materials, it is necessary to consider factors such as product requirements, material mechanical properties, wear resistance, and corrosion resistance. Commonly used mold materials include carbon steel, alloy steel, high-speed steel, hard alloy, etc.

3, Die processing

4, Mold assembly

5, Mold debugging

6, Mold acceptance

7, Mold maintenance

8, Mold scrapping

 

一

1. The temperature of the furnace should be controlled between 630 degree and 680 degree .

2. Observing the melted aluminum liquid, the suitable aluminum liquid for production appears bright white. If the aluminum liquid appears red, it indicates that the furnace temperature is too high. If the aluminum liquid is in the shape of ice cream, it indicates that the temperature is too low

3. It is strictly prohibited to mix impurities during the aluminum melting process, and it is prohibited for operators to privately put unqualified products into the furnace for remelting. If any products need to be remelted, they must be inspected and confirmed by the team leader before being put into remelting

4. Keep the aluminum liquid level stable and free from dross and bubbles. When scooping the aluminum liquid for die casting, the oxide layer and impurities on the surface of the aluminum liquid must be scraped off.

5. During the production process, powder refining agent and slag remover must be added twice in each shift in the furnace, with an average of once every 4 hours. The entire filling process must be carried out under the guidance of the team leader. After the operation is completed, impurities generated from refining must be cleaned before casting production can proceed.

6. During the production process, the bottom aluminum slag must be cleaned at least twice per shift, with an average of at least once every 4 hours.

7. All tools that come into contact with aluminum liquid must be dried first, and must be kept absolutely dry and clean, without impurities entering the aluminum liquid.

8. During the aluminum melting process, if excessive impurities are found in the aluminum ingots or returned materials, the same type of aluminum ingots or returned materials should be immediately put back into the furnace and reported to the team leader and workshop director in a timely manner.

1. Firstly, it is necessary to determine the accuracy of the mold model and ensure the integrity of the mold.

2. The assembly of molds should be completed with the joint assistance of operators, maintenance workers, and team leaders.

3. When assembling the mold, it is necessary to ensure the robustness of each fastener and ensure the safety of the mold during the production process.
