Technical field
Device is chatted the present invention relates to a kind of note on die casting machine, molten rifle is noted more particularly, to a kind of die casting machine.
Background technology
Die-casting technique be by the molten metal of molten state under high-voltage high-speed Fast Filling mold cavity, and make casting in high pressure
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 content of the invention
Problem to be solved by this invention is, for above-mentioned shortcoming of the prior art, proposes improvement project or replacement
Scheme, especially a kind of improvement or alternative for improving sealing effectiveness and heat insulation effect.
To solve the above problems, the scheme that the present invention is used is as follows：A kind of molten rifle of die casting machine note, it is characterised in that described
Noting molten rifle includes melting rifle component for the note of injection molten metal bath, for the die assembly of casting shaping and for providing injection
The drive mechanism of power, the note, which melts rifle component, includes barrel and the plunger being slidably arranged in the inner chamber of the barrel, described
The tail end of plunger is connected with the drive mechanism, and the plunger includes plunger rod, sliding block and stopper head, and the stopper head is arranged on
The top of plunger rod, the sliding block is arranged on one end away from stopper head on plunger rod, and the side wall of the stopper head is provided with and institute
The first sealing that material tube inner wall is slidingly sealed is stated, the end of the stopper head has trapezoidal groove, first sealing position
In the thin slice area with certain deformability formed between the trapezoidal groove and the stopper head outside wall surface, the barrel
On side wall be provided with cavity, spiral heater and molten metal passage are provided with the cavity, the molten metal passage sets spiral shell
The inside of heater is revolved, 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 located 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.
The technique effect of the present invention is as follows：The note being used on die casting machine of the application melts rifle, and plunger includes plunger rod and post
Chock plug, the side wall of stopper head is provided with the first sealing being slidingly sealed with material tube inner wall, and stopper head has trapezoidal groove, and first is close
Envelope portion is located in the thin slice area with certain deformability formed between trapezoidal groove and stopper head outside wall surface.Carrying out die casting
When, high-pressure smelting molten metal can be full of in the trapezoidal groove on stopper head, the high-pressure smelting molten metal applies one to thin slice area
Radial forces are so that thin slice area moderately expands, and thin slice area can strengthen between the first sealing and material tube inner wall after being radially expanded
Sealing intensity, and then prevent the molten metal bath to be shot material of high pressure from being dropped from the contact position leakage of the first sealing and material tube inner wall
Grazing shot material pressure or the amount for reducing the molten metal that shoots material, and then effectively reduce casting flaw.
The molten rifle of die casting machine note of the application, is provided with cavity on the side wall of barrel, and provided with spiral heater in cavity,
