Description
Technical field
The utility model is related to compression mod runner technical fields, more particularly to one kind being used for magnesium alloy branch built in tablet computer
The flow passage structure of frame.
Background technology
With the continuous development of compression mod, sheet metal products many at present all uses compression mod to produce, and is using pressure
When casting mould produces, the raw material of liquid directly flows into runner by cast gate, then is directly entered in cavity by runner, due to liquid
For raw material when pouring into, liquid material temperature, the pressure using high pressure, therefore in runner are larger, directly into cavity, due to pressure
Mold uses continuous production, therefore cavity is caused constantly to receive the impact of liquid material, causes die life of short duration, especially raw
Produce the plank of thinner thickness, the magnesium alloy bracket as built in tablet computer, in the actual production process, as shown in Figure 1, for giving birth to
The runner of the magnesium alloy bracket die casting built in tablet computer is produced in design, raw material is directly flowed into from vertical sprue 1
In cavity, and form product；High temperature and pressure raw material directly impacts the side of cavity, damages mold.
Invention content
The purpose of this utility model is that in view of the deficiencies of the prior art, providing a kind of for magnesium alloy built in tablet computer
The flow passage structure of holder, the flow passage structure can effectively reduce impact force of the liquid material to mold cavity, prolong the service life.
A kind of flow passage structure for magnesium alloy bracket built in tablet computer comprising cavity and vertical sprue, vertically
Sprue lower end is connected with vertical equity runner, and arced flow path, Zong Xiangshui are equipped between vertical equity runner and vertical sprue
The both ends in advection road are respectively equipped with blowdown exhaust buffers packet, and vertical equity runner is connected with transverse flow channels, and cavity is connected with width
The filling runner wide with cavity fills and is equipped with buffer runner, the cross section of the buffer runner between runner and transverse flow channels
20% of product no more than filling flow channel cross-section product.
Preferably, 10% of the cross-sectional area of buffer runner not less than filling flow channel cross-section.
Further, the both sides for filling runner also are provided with blowdown exhaust buffers packet.
Further, the middle part of the filling runner is to recessed.
Further, the both sides of cavity are respectively equipped with multiple cinder ladles.
Further, the rear end of cavity is connected with air discharge duct.
The beneficial effects of the utility model：The utility model, which passes through, is arranged dashpot so that fluid liquid is into cavity
When, speed slows down the impact mitigated to mold, extends the service life of mold.

Specific implementation mode
The utility model is described in detail below in conjunction with attached drawing.As shown in Figures 1 to 4.
Embodiment：A kind of flow passage structure for magnesium alloy bracket built in tablet computer comprising cavity 8 and vertical mainstream
Road, vertical sprue lower end are connected with vertical equity runner 3, arc stream are equipped between vertical equity runner 3 and vertical sprue
The both ends in road 2, vertical equity runner 3 are respectively equipped with blowdown exhaust buffers packet 5, and vertical equity runner 3 is connected with transverse flow channels 4,
Cavity 8 is connected with width and the wide filling runner 7 of cavity 8, fills and is equipped with buffer runner 11 between runner 7 and transverse flow channels 4,
20% of the cross-sectional area of the buffer runner 11 no more than filling 7 cross-sectional area of runner.
The technical program compared with the existing technology, is provided with buffer runner 11 in horizontal run, and the magnesium for deserving liquid closes
When gold enters buffer runner 11, the pressure in buffer runner 11 is suitable with the vertical pressure of sprue lower end, works as liquid magnesium alloy
When entering filling runner 7 from buffer runner 11, since cross section increases, the flow of buffer runner 11 is flowed through not in the unit interval
In the case of change, the liquid magnesium alloy speed into filling runner 7 slows down, i.e., reduces to the impact force of cavity 8, to effective
Mold is protected, is prolonged the service life.
When fluid liquid enters vertical equity runner 3 from vertical sprue, flow direction changes 90 degree so that can in fluid
Gas can be wrapped, to avoid wrapping gas, the technical program is provided with 2 transition of arced flow path.
Preferably, 10% of the cross-sectional area of buffer runner 11 not less than 7 cross section of filling runner.
7 cross-sectional area of filling runner described here refers specifically to the cross-sectional area of filling runner 7 and 8 junction of cavity.For
Do not influence whole flow velocity, the cross-sectional area of buffer runner 11 cannot be too small.
Further, the both sides of filling runner 7 also are provided with blowdown exhaust buffers packet 5.
When fluid liquid enters horizontal run, the gas in former horizontal run is extruded, since the direction of extruding exists
It is lateral to fill on runner 7 and vertical equity runner 3, it is therefore desirable in vertical equity runner 3 or/and fill the two of runner 7
Blowdown exhaust buffers packet 5 is respectively set in side.Blowdown exhaust buffers packet 5 is respectively set in the both sides of especially needed vertical equity runner 3.
Further, the middle part of the filling runner 7 is to recessed.
By the middle part for filling runner 7 to recessed, groove 6 is formed；So that the flow direction of flow channel for liquids changes, fluid rushes
It hits power to be buffered, slows down the impact force to cavity 8, protect mold.
Further, the both sides of cavity 8 are respectively equipped with multiple cinder ladles 9.
Due to the thinner thickness of magnesium alloy bracket built in tablet computer, and peripheral structure is complex, fluid liquid into
After entering, the liquid material on periphery is easy first to condense slagging；Cinder ladle 9 is set and is used for deslagging.
Further, the rear end of cavity 8 is connected with air discharge duct 10.
Gassy, setting air discharge duct 10 are conducive to, by the gas discharge inside cavity 8, avoid casting cavity 8 before filling
Contain gas in part.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as
Limitations of the present invention.
