Abstract
The present invention relates to a kind of efficient die castings of vacuum, including mode, setting type chamber inside the mode, cast gate is arranged in the mode top surface, and the cast gate is connected to type chamber, setting air discharge duct, exhaust block and aspirating hole inside the mode, gas vent is set in the exhaust block, communicate-type chamber on the inside of the gas vent, outside are connected to air discharge duct, and the air discharge duct is connected to aspirating hole.The efficient die casting of vacuum of the present invention, is designed by reasonable structure, and reasonable exhaust bleed-off passage is arranged inside mode, is become actively being evacuated from being passively vented, is improved the complete type of cavity filling, cast-internal stomata is few, and air-tightness is good.
Description
Technical field
The present invention relates to die casting mold fields, and in particular to a kind of efficient die casting of vacuum.
Background technique
The passive exhaust that existing mold mould intracavity gas individually leans on mold is difficult to reach the effect of exhaust, is passively vented
Process is exactly the process that metal is contacted with air-tight, and with the progress of exhaust, the intracavitary gas pressure of type can be gradually increased, more
Increase the possibility of the formation of stomata.Portion gas can be discharged from air drain, illustrate that the intracavitary air pressure of type is greater than atmospheric pressure, and
The pressure for finally filling type point will be the limit point of final type chamber air pressure, fly to expect in addition, being passively vented and also most probably will cause metal,
Injection efficiency is reduced, environment is polluted and brings security risk.Therefore, prior art mold filling is incomplete, in lower road work
There is the air and gas porosity in sequence, and the porosity causes tensile strength to weaken, while cast-internal organizational slack, poor air-tightness.
Summary of the invention
The purpose of the present invention is to provide a kind of efficient die castings of vacuum, to solve cavity filling in the prior art
Scheme leads to the problem of incomplete cavity filling, cast-internal poor air-tightness.
The present invention provides a kind of efficient die casting of vacuum, including mode, setting type chamber inside the mode, the mould
Cast gate is arranged in benevolence top surface, and the cast gate is connected to type chamber, and setting air discharge duct, exhaust block and aspirating hole, described inside the mode
Gas vent, communicate-type chamber on the inside of the gas vent are set in exhaust block, and outside is connected to air discharge duct, the air discharge duct connection pumping
Hole.
Further, seal groove is arranged in the air discharge duct periphery, and sealing strip is arranged in the seal groove.
Further, pressure gauge is set on mode, and the pressure gauge is connected to air discharge duct.
Beneficial effect using aforementioned present invention technical solution is:
The efficient die casting of vacuum of the present invention, is designed by reasonable structure, and reasonable exhaust is arranged inside mode and takes out
Gas channel becomes actively being evacuated, improves the complete type of cavity filling, cast-internal stomata is few, and air-tightness is good from being passively vented.
Detailed description of the invention

Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.
As shown in Figure 1, the present invention provides a kind of efficient die casting of vacuum, including mode 1, set inside the mode 1
Set type chamber 2, cast gate 3 is arranged in 1 top surface of mode, and the cast gate 3 be connected to type chamber 2, setting air discharge duct 4 inside the mode 1,
Exhaust block 5 and aspirating hole 6, the exhaust block 5 is interior to be arranged gas vent 7, the 7 inside communicate-type chamber 2 of gas vent, outside connection row
Air drain 4, the air discharge duct 4 are connected to aspirating hole 6.In the embodiment, casting feedstock is poured into inside type chamber 2 by cast gate 3, outside pumping
Mechanism connects aspirating hole 6, actively extracts the gas in type chamber 2 out by air discharge duct 4 and aspirating hole 6, increases the airtight of casting
Property.
Further, in the embodiment, the 4 periphery setting seal groove 8 of air discharge duct, the interior setting sealing of the seal groove 8
Item increases the air-tightness of mode 1.
Pressure gauge 9 is set on mode 1, and the pressure gauge 9 is connected to air discharge duct 4, air pressure in real-time detection air discharge duct 4.
To sum up, the efficient die casting of vacuum of the present invention is designed by reasonable structure, and reasonable row is arranged inside mode
Gas bleed-off passage becomes actively being evacuated, improves the complete type of cavity filling, cast-internal stomata is few, air-tightness from being passively vented
It is good.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
