Lower coagulation forming, it 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 from barrel molten metal in mould and carry out with molded.Due to injected in barrel be molten state gold
Belong to liquation, temperature is very high, and certain pressure that shoots material must be carried in material shooting process, this require plunger and material tube inner wall it
Between there is 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 what is moved reciprocatingly in the barrel penetrate splenium part
(plunger), seal is additionally provided between part and barrel shooting material, 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 wears larger when being moved reciprocatingly in barrel；In addition, and due to barrel and penetrate splenium part and be 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, the feed liquid deficiency in mould is caused.
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 cause gold
The temperature of category fused solution rapidly reduces, and is unfavorable for die cast.
Utility model content

Alternative, especially a kind of improvement or alternative for improving sealing effectiveness and heat insulation effect.
To solve the above problems, the scheme that the utility model uses is as follows：A kind of molten rifle of die casting machine note, it is characterised in that
The molten rifle of note includes melting rifle component for the note of injection molten metal bath, for the die assembly of casting shaping and for providing
The drive mechanism of injection power, the molten rifle component of note include barrel and the plunger being slidably arranged in the inner chamber of the barrel,
The tail end of the plunger is connected with the drive mechanism, and the plunger includes plunger rod, sliding block and stopper head, and the stopper head is set
Put at the top of plunger rod, the sliding block is arranged on one end away from stopper head, the side wall of the stopper head on plunger rod and is provided with
The first sealing being slidingly sealed with the material tube inner wall, the end of the stopper head have trapezoidal groove, first sealing
It is described in the thin slice area with certain deformability that portion is formed between the trapezoidal groove and the stopper head outside wall surface
Side wall on barrel is provided with cavity, is provided with spiral heater and molten metal passage in the cavity, the molten metal passage is set
The inside of spiral heater is put, the tail end of the molten metal passage is connected to Metal Melting room.
Further, the molten rifle of die casting machine note according to above-mentioned design, it is characterised in that the side wall of the sliding block is provided with
The second sealing being slidingly sealed with the material tube inner wall.
Further, the molten rifle of die casting machine note according to above-mentioned design, it is characterised in that the molten metal passage includes
Interconnection and vertical passageway, the interconnection are arranged on the inside of spiral heater, and the vertical passageway is used for binder
Cylinder and interconnection.
Further, the molten rifle of die casting machine note according to above-mentioned design, it is characterised in that the stopper head is positioned at trapezoidal
The end cross-sectional thickness of groove is less than bottom section thickness.
Further, the molten rifle of die casting machine note according to above-mentioned design, it is characterised in that the molten metal passage passes through
Pipeline is connected with molten metal working chamber.
Technique effect of the present utility model is as follows：The note being used on die casting machine of the application melts rifle, and plunger includes plunger rod
And stopper head, the side wall of stopper head are provided with the first sealing being slidingly sealed with material tube inner wall, stopper head has trapezoidal groove, the
In the thin slice area with certain deformability that one sealing position is formed between trapezoidal groove and stopper head outside wall surface.Carry out
During die casting, high-pressure smelting molten metal can be full of in the trapezoidal groove on stopper head, the high-pressure smelting molten metal applies to thin slice area
One radial forces so that thin slice area moderately expands, thin slice area can strengthen after being radially expanded the first sealing and material tube inner wall it
Between sealing intensity, and then prevent the molten metal bath to be shot material of high pressure from being leaked from the contact position of the first sealing and material tube inner wall
And reduce and shoot material pressure or reduce the amount of molten metal of shooting material, and then effectively reduce casting flaw.
