Description
Technical field
The utility model is related to a kind of open type barrels for Semi-solid Thixo-Casting with thermal balance structure, and belonging to has
Non-ferrous metal casting forming field.
Background technology
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 filled in the cavity of compression mod with high speed, and molten metal cooled and solidified is made to be molded 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 are rectangular or circular open, liquid metal to pour into barrel from there, subsequently completes and fill type, pressurization, solidification forming；And semisolid
Viscosity of Liquid Metal is higher, can not flow freely, cannot from cylinder closed-loop shaped barrel it is open-ended from pour into, therefore the structure
Barrel cannot meet the production requirement of semisolid pressure casting technique.In addition, it is not provided with heating device on cylinder closed-loop shaped barrel,
After being put into wherein between barrel heat transfer, which occurs, for semi-solid metal slurry/blank 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, since mould steel expands with heat and contract with cold phenomenon, the top of the barrel, lower temperature unevenness cause concentricity to reduce and influence material
The cooperation of cylinder and punch reduces the service life of 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.
