Abstract

The invention discloses a high-vacuum die casting device with bidirectional vacuumizing. The high-vacuum die casting device comprises a fixed die plate, a moving die plate corresponding to the fixed die plate, a die cavity, a flow gate connected with the die cavity, a pressure chamber, a spreader for connecting a charging barrel with the flow gate, an ejection rod for casting feed liquid inside the charging barrel, an ejection head positioned at one end of the ejection rod, a pouring slot communicated with the charging barrel, a vacuumizing device, and a vacuum tube connected with the vacuumizing device and communicated with the die cavity, wherein ventilation holes are formed in the charging barrel between the pouring slot and the spreader, and are connected with the vacuumizing device through the vacuum tube 13. As the high-vacuum die casting device adopts the structure, a vacuumizing point is added on the charging barrel and form a bidirectional vacuumizing system with a vacuumizing part on a die. Through the bidirectional vacuumizing manner, the vacuum degrees inside the pressure chamber and the die cavity can be within 100mbar in a short time of no more than 0.5s, and thus the high-vacuum die casting device is suitable for die castings with very high requirements on air holes.

Description

A kind of two-way high vacuum die casting device that vacuumizes
Technical field
The present invention relates to a kind of die casting equipment, particularly a kind of two-way high vacuum die casting device that vacuumizes.
Background technology
Vacuum pumping technology is to reduce effective exhaust means that die casting forms pore.Generally vacuumize now the place and only be arranged on the mould, because in barrel, aluminium alloy contacts even wrap up gas with the gas large tracts of land, can not discharge, rest at last and form pore in the aluminium alloy, this does not reach requirement concerning the die casting that pore has high requirements.
Summary of the invention
The deficiency that the present invention exists in order to overcome above-mentioned prior art provides and can form the two-way a kind of two-way high vacuum die casting device that vacuumizes that vacuumizes with mould in barrel.
The present invention can be achieved by taking following technical scheme:
A kind of two-way high vacuum die casting device that vacuumizes, comprise solid plate, the moving platen corresponding with solid plate, die cavity, the ingate that links to each other with die cavity, press the chamber, is connected barrel and ingate spreader, the feed liquid in the barrel is carried out penetrating bar, being positioned at a vacuum tube of penetrating, and link to each other with vacuum extractor and be communicated with pouring slot, the vacuum extractor that barrel communicates die cavity of penetrating boom end of die casting, be provided with passage on the described barrel between pouring slot and spreader, passage links to each other with vacuum extractor by vacuum tube 13.
Described vacuum extractor comprises vavuum pump and electrical control cubicles.
Be respectively equipped with magnetic valve on the vacuum tube of described connection die cavity and the vacuum tube that is connected passage.
In order to control more accurately the beginning and ending time that vacuumizes in the barrel, the encoder of determining the drift position is set penetrating bar, this encoder is connected with the electrical control cubicles signal of vacuum extractor.
On described barrel, the vacuum sound-pipe can also be set, be used for picking up its vacuum of survey.
The distance that vacuumizes passage and pouring slot on the described barrel is 1/5th of barrel length.
The present invention has been owing to adopted said structure, increases at barrel to vacuumize a little, consists of two-way pumped vacuum systems with vacuumizing on the mould.Can determine the drift position by the encoder of penetrating on the bar.When injection punch head surpassed pouring slot, encoder formed signal and passes to electrical control cubicles, the vavuum pump running, and vacuum valve is opened, and two ends begin to bleed simultaneously.The vacuum sound-pipe can record the vacuum of pressing in chamber and the die cavity.When drift arrived vacuumizing on the barrel, the vacuum valve on the barrel cut out, and the pumped vacuum systems on the mould continues to bleed, until aluminium alloy is full of die cavity, the vacuum valve on the mould cuts out, and vavuum pump shuts down, and whole vacuum is complete.Adopting this two-way mode that vacuumizes, can often be that the vacuum of pressing in chamber and the die cavity is reached in the 100mbar in very short time, is applicable to the die casting that pore is had high requirements.
  
Description of drawings
Fig. 1 is structure chart of the present invention.
Fig. 2 is material cylinder structure figure.
The specific embodiment
Below in conjunction with accompanying drawing most preferred embodiment of the present invention is described in detail.
As depicted in figs. 1 and 2, a kind of two-way high vacuum die casting device that vacuumizes of the present invention, comprise solid plate 1, the moving platen 2 corresponding with solid plate, die cavity 3, the ingate 4 that links to each other with die cavity 3, press chamber 5, the spreader 6 that connects barrel and ingate, penetrate bar 7 to what the feed liquid in the barrel was carried out die casting, be positioned at penetrate boom end penetrate 8, the pouring slot 9 that communicates with barrel, vacuum extractor 10 with link to each other with vacuum extractor and be communicated with the vacuum tube 11 of die cavity, be provided with passage 12 on the described barrel between pouring slot and spreader, passage links to each other with vacuum extractor by vacuum tube 13; Described vacuum extractor comprises vavuum pump 14 and electrical control cubicles 15; Be respectively equipped with magnetic valve 16 on the vacuum tube of described connection die cavity and the vacuum tube that is connected passage.
In order to control more accurately the beginning and ending time that vacuumizes in the barrel, the encoder of determining the drift position is set penetrating bar, this encoder is connected with the electrical control cubicles signal of vacuum extractor.
On described barrel, vacuum sound-pipe 18 can also be set, be used for picking up its vacuum of survey.
The distance that vacuumizes passage and pouring slot on the described barrel is 1/5th of barrel length.
The above person of thought, only for the present invention's preferred embodiment, when the scope that can not limit with this invention process, the content of namely generally putting down in writing according to claim of the present invention and description of the invention has been done simple equivalence and has been changed and modify, and all still belongs within the claim of the present invention institute covering scope.In addition, summary part and title only are the usefulness of auxiliary patent document search, are not the interest field that limits the present invention.
