Description
Technical field
The utility model relates to low-pressure die casting plant field more particularly to a kind of stalks of built-in filter.
Background technique
Stalk is a kind of part for low pressure casting.The process flow of low pressure casting is: casting mold is placed in sealing
Crucible above, compressed air is then passed through into crucible, low-pressure is caused on the surface of molten metal, makes molten metal by rising
Liquid pipe rises filling cast and controls solidification.The stalk of the prior art is the pipe-shaped parts of inside diameter gradual change, to molten metal
Body does not have filtration, be easy to cause following defect: 1, the intracorporal sundries of molten metal enters in mold in cavity filling process, makes
It obtains cast(ing) surface and forms hole；2, the big sundries of metal liquid inside dimension blocks feed inlet when filling type, causes Filling Processes of Castings not
Foot；3, sundries is adhered in stalk inner wall, reduces stalk service life；4, after filling type completion and pressure release, liquid in stalk
Reflux is fast, is easy to produce secondary oxidation.
Utility model content
The technical problems to be solved in the utility model is that filter is added in stalk, avoid sundries enter stalk and
In mold, while reducing the back-flow velocity of liquid in stalk.
In order to solve the above technical problems, the technical solution adopted by the utility model is: a kind of liter liquid for low pressure casting
Pipe, including long tube and the filter being mounted on inside long tube；
Filter is rounded, and filter hole is provided on filter, and the edge of filter is provided at least one auricle；In order to
Quantity two of the stabilization of filter, auricle are preferred；
Long tube includes pipe shaft and nozzle, and pipe shaft and nozzle joining place, which are provided with, is embedded in filtering inside long tube for accommodating
The annular groove of piece is provided with the auricle channel towards annular groove at nozzle, and the cross sectional shape in auricle channel is consistent with auricle, auricle
The quantity in channel and the quantity of auricle are consistent.
Further, the interior diameter D of the nozzle1Greater than the diameter d of filter1, d between filter1Not less than pipe shaft
Interior diameter D3, the diameter D of annular groove2Twice of value d of the maximum distance not less than ear edge apart from filter center2。
Annular groove in order to facilitate processing, the wall thickness of the nozzle are greater than the wall thickness of pipe shaft.
Further, the nozzle, which refers to, is inserted into molten metal intracorporal nozzle when stalk uses, so that filter is rising
To the back-flow velocity that can also reduce liquid in stalk while filtration.
The utility model has the advantages that filter is arranged in the stalk of (1) the utility model in nozzle, effectively intercepts sundries and enter a liter liquid
In pipe and mold, avoids sundries from blocking feed inlet, improve the yield rate of casting；Prevent sundries and be adhered to stalk inner wall, improves
The service life of stalk.(2) filter is designed as ear slice structure by the stalk of the utility model, filter and long tube it
Between be flexibly connected, installation and removal are convenient, are conducive to the replacement of filter.(3) stalk of the utility model sets filter
In the least significant end of stalk, after the completion of filling type, filter can also slow down the back-flow velocity of molten metal, avoid the gold in stalk
Belong to liquid and impact is generated to the intracorporal storage metal liquid of furnace, reduces the Secondary Oxidizing Slag that secondary oxidation generates.

Specific embodiment
The utility model is described in further detail With reference to embodiment.
Embodiment 1
As shown in Figures 1 to 4, the stalk for low pressure casting of the present embodiment, including long tube 1 and it is mounted on long tube 1
Internal filter 2；
Filter 2 is rounded, and filter hole is provided on filter 2, and two evaginations are symmetrically arranged in the edge of filter 2
Auricle 201；2 diameter of filter is d1, the maximum distance at two 201 edges of auricle is d2。
Long tube 1 includes pipe shaft 101 and nozzle 102, and the wall thickness of nozzle 102 is greater than the wall thickness of pipe shaft 101；Pipe shaft 101 and pipe
102 joining places of mouth are provided with the annular groove 103 for being used to accommodate filter 2 being embedded in inside long tube 1, are provided at nozzle 102
Towards the auricle channel 104 of annular groove 103, the cross sectional shape and auricle 201 in auricle channel 104 are consistent, the number in auricle channel 104
It measures consistent with the quantity of auricle 201；The interior diameter of nozzle 102 is D1, the interior diameter of annular groove 103 is D2, pipe shaft 101 it is interior straight
Diameter is D3；The size of filter 2 and long tube 1 meets following relationship:
D1>d1, d1≥D3, D2≥d2。
2 separate machined of long tube 1 and filter of the present embodiment, will be at the auricle 201 of filter 2 and nozzle 102 when assembling
Auricle channel 104 be aligned, filter 2 is filled in the annular groove 103 of 102 bottom of nozzle, then rotates through 290 ° of filter disc or so
；When disassembly similarly.
The stalk of the present embodiment in use, nozzle 102 shown in Fig. 1 is inserted into the metal liquid in furnace downward,
Filter 2 can effectively block sundries and enter in stalk and mold, avoid sundries from blocking feed inlet, improve the finished product of casting
Rate；Prevent sundries and be adhered to stalk inner wall, improves the service life of stalk；After the completion of filling type, filter 2 can also slow down
The back-flow velocity of molten metal avoids the metal liquid in stalk from generating impact to the intracorporal storage metal liquid of furnace, reduces two
The Secondary Oxidizing Slag that secondary oxidation generates.
Although the embodiments of the present invention is illustrated in specification, these embodiments are intended only as mentioning
Show, should not limit the protection scope of the utility model.Various omissions are carried out in the range of not departing from the utility model aims, are set
It changes and change should be included in the protection scope of the utility model.
