The dimensional precision of the die casting.
The dimensional precision of the die casting is high. It is the
crown of all kinds of casting methods, and its stability (the time
of keeping this precision) is also very good. It is basically based
on the machining precision of the die casting die. But there are
many factors that affect the accuracy of die casting, and they are
interrelated and influenced.
These factors are mainly caused by the deviation of the chemical
composition of the alloy itself, the shrinkage rate is different,
the degree of deformation is different, the calculated shrinkage
rate is deviant from the actual shrinkage of the alloy; the design
structure of the casting is not reasonable, such as the casting
thin and no reinforcement, which leads to the deformation or
cracking of the casting when the die is ejecting, and the wall
thickness is not uniform.
In the casting, the shrinkage is not consistent and the internal
stress is different. The casting is less inclined and the mold
difficulty is increased; the deformation or fracture causes the
dimensional accuracy, the opening and the core pulling, the
stability of the movement state of the mechanism, the error caused
by the grinding loss in the mold use process; the die casting
Deviation of the number, error caused by the precision and rigidity
of the die-casting machine; the error produced by the number of
moulds, the deviation of the calculation and manufacture of the
forming parts; improper selection of the mold material, the core
pulling and the introduction of the mold; the position of the
casting in the mold (i.
e. the improper selection of the type surface); the casting die
temperature, the injection velocity and the ratio of the casting.
