Abstract
The utility model discloses a last vacuum bleeder valve of die casting die, which comprises the following components: a valve body, be equipped with the valve pocket in the valve body, valve pocket one end is equipped with the air inlet, be equipped with the case that can be close to or keep away from the air inlet in the valve pocket, be equipped with the vacuum exhaust tube that is linked together with the valve pocket on the valve body, the vacuum exhaust tube links to each other with the vacuum machine, when the air inlet certain distance is kept away from to the case, thereby the case makes the sealed butt of case and valve pocket inner wall with valve pocket inner wall looks adaptation, vacuum machine stop work, and when the case was close to the air inlet, the gas that gets into the valve pocket from the air inlet was taken out to the vacuum machine. The vacuum machine can be taken out the gas of mould intracavity before aluminium alloy product die -casting is filled, makes the mould intracavity reach certain vacuum, in die -casting in -process reduction gas is drawn into aluminium liquid, and improvement die -casting aluminium alloy product's quality.
Description
Technical field
The utility model relates to a kind of extraction valve, the vacuum extraction valve particularly on a kind of die casting mould.
Background technique
Energy-saving and emission-reduction are carried out energetically in the current whole world, Vehicle mass reduction be must trend, because vehicle body series products is higher to internal porosity quality requirement, due to product wall thickness thinner easy generation volume conductance, to cause interiors of products quality undesirable in high-speed filling process for pack alloy product.Mostly adopt when pack alloy product passive type to discharge mould intracavity gas at present, the internal soundness of product cannot be ensured.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide the vacuum extraction valve on a kind of die casting mould, initiatively extracts mould intracavity gas out, reduces gas in press casting procedure and is involved in aluminium liquid, improve the quality of pack alloy product.
To achieve these goals, vacuum extraction valve on a kind of die casting mould designed by the utility model, comprise valve body, valve pocket is provided with in described valve body, described valve pocket one end is provided with suction port, be provided with in described valve pocket can near or away from the spool of suction port, described valve body is provided with the vacuum exhaust pipe be connected with valve pocket, described vacuum exhaust pipe is connected with vacuum machine, when spool is away from suction port certain distance, described spool is suitable with valve pocket inwall thus spool is abutted with valve pocket inner wall sealing, vacuum machine quits work, when spool is near suction port, vacuum machine extracts the gas entering valve pocket from suction port out.
Further, described valve pocket runs through valve body two ends, and it is outer and be connected with driving mechanism that described spool is exposed to valve pocket away from suction port one end.
Further, described valve pocket is provided with sealing block away from suction port one end, is provided with valve body height adjusting blocks below described sealing block.
Further, described spool is provided with position limit switch touching block near driving mechanism place, and the trip switch touching block can contact with position limit switch at moving process, and described position limit switch is positioned on rapid connection plate.
Preferably, described driving structure is oil cylinder.
Further, described spool is provided with projection near suction port one end, and described projection side is by close spool one end to the close outward-dipping setting in suction port one end, and described valve pocket inwall is provided with the inclined-plane suitable with projection side.
Vacuum extraction valve on a kind of die casting mould that the utility model obtains, its technique effect is: the gas in mold cavity can pump by vacuum machine before alloy product die casting is filled, make in mold cavity, to reach certain degree of vacuum, in press casting procedure, reduce gas is involved in aluminium liquid, improves the quality of pack alloy product.
Accompanying drawing explanation
Fig. 1 is structural representation when vacuum machine quits work in the utility model.
Fig. 2 is the partial enlarged drawing at A place in Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, vacuum extraction valve on a kind of die casting mould that the utility model provides, comprise valve body 1, valve pocket 2 is provided with in valve body 1, valve pocket 2 runs through valve body 1 two ends, and valve pocket 2 one end is provided with suction port 3, be provided with in valve pocket 2 can near or away from the spool 4 of suction port, it is outer and be connected with driving mechanism that spool 4 is exposed to valve pocket 2 away from suction port 3 one end, thus make spool close or away from suction port by driving mechanism.
Valve body 1 is provided with the vacuum exhaust pipe 5 be connected with valve pocket 2, vacuum exhaust pipe 5 is connected with vacuum machine, when spool is away from suction port certain distance, described spool is suitable with valve pocket inwall thus spool is abutted with valve pocket inner wall sealing, vacuum machine quits work, when spool is near suction port, vacuum machine extracts the gas entering valve pocket from suction port out.
Wherein, spool 4 is provided with projection 12 near suction port one end, projection side by near spool one end near the outward-dipping setting in suction port one end, valve pocket inwall is provided with the inclined-plane 13 suitable with projection side, thus when making spool away from suction port certain distance, projection side abuts with valve pocket inner wall sealing.
In the present embodiment, valve pocket 2 is provided with sealing block 6 away from suction port 3 one end, sealing block 6 can ensure that the gas outside valve body 1 enters in valve pocket from the valve chamber open end away from suction port one end, the gas simultaneously entered in valve pocket from suction port does not also overflow from here, valve body height adjusting blocks 7 is provided with below sealing block 6, height adjusting blocks 7 can be connected with valve pocket inner thread, also can adopt other modes, ensure spool in moving process sealing block be sealed with validity.
Spool 4 is provided with position limit switch touching block 8 near driving mechanism place, the trip switch touching block 8 can contact with position limit switch 9 at moving process, and position limit switch 9 is positioned on rapid connection plate 10.
In the present embodiment, driving structure is oil cylinder 11.
Working principle of the present utility model: the spool suction port 3 of this vacuum extraction valve is connected with cavity body of mould by bypass channel, oil cylinder 11 is connected with die casting board signal, when aluminium liquid enters cavity body of mould from material pipe, vacuum machine runs, gas in cavity body of mould is constantly extracted out from spool suction port, make the degree of vacuum reaching-150bar in mold cavity, when needing to close vacuum machine, die casting board sends signal to oil cylinder, oil cylinder pulls spool 4 away from suction port, after spool runs certain distance, abut with valve pocket 2 inner wall sealing, thus make the gas in cavity body of mould and vacuum machine isolated, now, position limit switch touching block 8 on spool contacts with position limit switch 9, thus stop vacuum machine running and cylinder action.Take out aluminium alloy castings product after die sinking, oil cylinder pushing valve core reset, spool recovers opening state, and the aluminium that valve body is blown in removal valve pocket is considered to be worth doing, can enter bleeding of next product.
