Description
Technical field
The present invention relates to a kind of thermal balance temperature control methods for Semi-solid Thixo-Casting open type barrel, and belonging to has coloured gold
Belong to casting forming field.
Background technique
Conventional liquid die casting is a kind of barrel that the metallic solution of molten condition is poured into die casting machine, in the effect of high pressure
Under, it is intracavitary with the type that high speed is filled in compression mod, and molten metal cooled and solidified is made to form and obtain casting under high pressure
High benefit, efficient casting method.Semi-solid Thixo-Casting technique basic principle is identical as conventional liquid die casting, but
Semi-solid Thixo-Casting technique is semi-solid metal slurry/blank to be put into charging barrel of die casting machine, then filled, pressurizeed, coagulated
Gu forming.Two kinds of technique main distinctions are the metallic state differences being put into barrel, and what conventional liquid die casting was selected is pure liquid
Metal, and semisolid pressure casting select be solid-liquid admixture semi-solid-state metal.The semi-solid-state metal of solid-liquid admixture is outstanding
It its when fraction solid is higher (fraction solid reaches 30% or more), can not flow freely under the effect of gravity, itself can be kept
Intrinsic shape.
The barrel used in conventional liquid casting forming technique is opened in its end close to forcer position for cylinder closed-loop shaped
There is rectangular or circular open, liquid metal pours into barrel from there, subsequently completes and fills type, pressurization, solidification forming；And semisolid

Barrel is not able to satisfy the production requirement of semisolid pressure casting technique.In addition, it is not provided with heating device on cylinder closed-loop shaped barrel,
Between barrel heat transfer, which occurs, for semi-solid metal slurry/blank after being put into wherein causes local temperature to decline rapidly, semisolid blank
Material temperature degree, nonuniform organization influence the quality of post forming part, cause cold shut, fill the casting flaws such as type is bad.
In addition, existing closed-loop shaped or opening shape barrel cannot be guaranteed that barrel bulk temperature is uniform, barrel temperature up and down is caused
Inconsistent phenomenon, due to mould steel thermal expansion and contraction, the top of the barrel, lower temperature unevenness cause concentricity to reduce and influence material
The cooperation of cylinder and formed punch reduces the service life of formed punch and barrel.
During replacing barrel, since barrel temperature is excessively high, temperature fall time is long, influences engineer's operation, and high temperature is made
Industry increases security risk.
