Description
Technical field
The utility model belongs to Low Pressure Casting Technology field, and in particular to a kind of stalk of low pressure casting.
Background technology
In Low Pressure Casting Technology, stalk is the unique passage for connecting holding furnace and mold cavity, the structure of stalk
Feature, heat insulation effect and corrosion resistance etc. directly affect the quality of casting.Stalk is general in common casting process
Using cylinder straight tube, the aluminium liquid and stalk heat exchange to take the lead in into mould is big, and thermal loss is larger, and stalk easily occurs
Phenomenon of freezing to death shifts to an earlier date solidification phenomenon into die cavity；After crystallization pressurize terminates, the resistance that aluminium liquid backflow is subject in straight tube is small,
The holding furnace the bottom of a pan is washed away seriously, while the easily impurity at agitated kettle bottom, mould is easily added impurities in next casting process
Casting quality can not be ensured.
The content of the invention
In order to solve above-mentioned problem, the utility model provides a kind of stalk of low pressure casting.
What the technical solution of the utility model was realized in：The steel pipe that stalk is structure as a whole, including the 3rd filtering
Piece, the second filter, the first filter, inverted cone-shaped drainage trough, ring flange, counter sink, upper bellows, lower bellows, cylinder are straight
Pipe, filter disc.The materials such as alumina titanate ceramics raising stalk can be added inside stalk to give full play to the function of stalk
Resistance to corrosion, the insulating power that the materials such as carborundum improve stalk is added outside stalk.
As further prioritization scheme of the present utility model, the counter sink is evenly distributed on the flange panel surface, leads to
Sunk screw is crossed to be closely joined together stalk and heat insulation furnace cover；Between the inverted cone-shaped drainage trough and the upper bellows
For the cylinder straight tube；It is the cylinder straight tube between the upper bellows and the lower bellows；It is the upper bellows, described
Lower bellows and the cylinder straight tube junction are rounded corner；The upper bellows and the lower ripple tube pitch are 1.5cm；Institute
The maximum inner diameter for stating bellows and the lower bellows is 1.1-1.2 times of the cylinder straight tube internal diameter.
As further prioritization scheme of the present utility model, the ring flange is the upper end of stalk；The cylinder straight tube
For the lower end of stalk；First bellows close to the inverted cone-shaped drainage trough is the upper bellows；First filtering
Piece is placed in the upper end junction of the upper bellows and the cylinder straight tube；The diameter of first filter is equal to the cylinder
The internal diameter of straight tube；Second filter is located at the lower end of first filter；Second filter and first mistake
The distance of filter disc is about 0.25 times of the cylinder straight tube internal diameter；The bellows of the upper bellows lower end is the lower ripple
Pipe；Position of 3rd filter in the lower bellows and position of second filter on described in bellows
It is identical；First filter, second filter, there are the wide strip filter openings of 3cm, filter opening area on the 3rd filter
The 40% of about described filter disc area；The filter disc thickness is 5mm；The filter opening of first filter and second filter
Filter opening be disposed vertically.
Three layer filtration piece of the present utility model can be very good to play skimming effect, while can also ensure that aluminium liquid is stable
It flow in casting mold.Bellows can improve the fluid ability of the heat-exchange capacity and aluminium liquid between aluminium liquid, and then avoid a liter liquid
Pipe, which is freezed to death, phenomenon or shifts to an earlier date solidification phenomenon into die cavity；Meanwhile the backflow resistance of aluminium liquid is improved, avoid washing away holding furnace
Phenomenon；The use of bellows can absorb the thermal deformation brought by temperature change, further improve the life-span of stalk.
