Lower coagulation forming, is current production efficiency highest casting technique.Casting shoot material during die cast, it is necessary to first
Molten metal liquation is first heated into alloy material, then molten metal is directed into the barrel of material injection device again, is finally led to
Cross plunger and push to molten metal in mould from barrel and carry out with molded.Due to injected in barrel be molten state gold
Belong to liquation, temperature is very high, and in material shooting process must with certain pressure that shoots material, this require plunger and material tube inner wall it
Between have good sealing effectiveness.
As Chinese patent document CN201618837U discloses a kind of non-crystaline amorphous metal vacuum material injection device and including the vacuum
The die casting machine of material injection device, its material injection device mainly include barrel, and moved reciprocatingly in the barrel penetrate splenium part
(plunger), seal is additionally provided with shooting material between part and barrel, the seal, which is fixed on, to be penetrated on splenium part, seal master
To be cushion rubber hydrostatic seal or magnetic seal.Due to being face sealing between the seal and material tube inner wall in the patent document, penetrate
Splenium part weares and teares larger when being moved reciprocatingly in barrel；In addition, and due to barrel and penetrating splenium part and being both needed to work at high temperature
Make, and high temperature can further result in that its bulk material softens, this further exacerbates wear extent during relative motion, causes
Make seal short life, it is unreliable to seal；When particularly shooting material at elevated pressures, molten metal bath and easily from seal with
Gap location between material tube inner wall is spilt, and this can not only make injection pressure not reach default injection pressure, or even can be because leakage
Excessively, cause the feed liquid in mould not enough.
Meanwhile, the material feeding rifle of the die casting machine of prior art is general for the heat insulation effect of molten metal bath, easily causes gold
The temperature of category fused solution is rapidly reduced, and is unfavorable for die cast.The die casting machine of prior art exist die casting foaming it is uncontrollable, need
Just continuously largely to inject molten metal can guarantee that elimination foaming, larger for production cost, in order to production cost is further reduced,
The application is provided with vibrations froth breaker in the molten rifle of note.
