Die casting Mold production  and precautions

We all know that in the Die casting Mold production should be done before the warm-up action, the following is its role:

1, Die casting Mold production，die-casting mold can do a good heat balance, so that die-casting mold uniform and rapid solidification to help the pressure transmission;

2, to maintain a good liquidity, to fill the die casting die in the die when the good formability and improve the surface quality of die casting;

3, to reduce the die-casting mold heat exchange stress, lost wax casting, improve the life of the mold;

4, to reduce the poor pre-production and the corresponding increase in the productivity of die casting.

Die casting Mold production has a lot of pressure, we must pay attention to the use of alternating, to get from the mold material, design, processing, heat treatment and operating life of the mold, if the mold to extend the life of the mold can be achieved:

1, to the principle of good quality die casting mold material;

2, according to the actual situation of the design of the mold wall thickness and the size of the mold;

3, pay attention to roughing after roughing;

4, the use of the correct heat treatment, quenching to be fast enough;

5, thoroughly polished to remove EDM harassment quality layer;

6, the surface is not highly polished

7, less aluminum, to speed up the injection rate;

8, to a good cooling mold, the temperature of the water used to cool the mold control at 40 to 50 ℃;

9, in the temporary downtime, you can try to shape and reduce the amount of cooling water to avoid the boot when the die-casting mold to withstand thermal shock;

10, Die casting Mold production mold surface to reach the maximum temperature, to close the coolant.
