Principles for selecting the working temperature of the mold temperature machine:
1) The mold temperature is too low, the internal structure of the casting is loose, and it is difficult to discharge air, making it difficult to form.
2) "The mold temperature is too high, and the internal structure of the casting is dense, but the casting is prone to" welding "in the mold cavity, making it difficult to adhere to the mold and unload the casting. At the same time, excessive temperature will cause the mold to expand, affecting the dimensional accuracy of the casting.".
3) The mold temperature should be selected within a suitable range. Generally, after testing, constant temperature control is preferred.
The following points should be noted in die casting production:
1) Material melting temperature Mold temperature and solution temperature during injection;
2) The determination of injection pressure, mold locking force, mold opening force, and the required injection ratio, injection speed, etc. according to the condition of the workpiece;
3) It is necessary to recuperate the condition of the die cast product to obtain a perfect product;
