Description
Technical field
Casting technology field is the utility model is related to, more particularly to a kind of metal-mold low-pressure casting sealing device.
Background technology
With the development of science and technology, the requirement of low-carbon life, automotive light weight technology technology is that the technology of major automaker is difficult
Topic, secondary support, stent and the car door roof for now replacing steel using aluminium alloy progressively use on superior automobile, and are used for automobile
On each parts alloy product technical requirements it is at a relatively high, iron-holder requirement be less than 0.12%, elongation percentage be more than 9%,
Under such technical conditions, product will not ensure that in casting process using hawkbill pot, the iron phase clamped in pot does not fuse into aluminium water
In, therefore use graphite pincers pot to replace hawkbill pot to reduce the content of iron, it is ensured that iron-holder is less than 0.12%, but again there is
One problem is exactly graphite pincers pot, it is impossible to which excessive pressure-bearing, therefore, the present inventor not only clamp pot with graphite using one kind but also do not allow
Graphite clamps the metal-mold low-pressure casting sealing device of pot pressure-bearing.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of metal-mold low-pressure casting that can improve load performance
Use sealing device.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of metal-mold low-pressure casting is filled with sealing
Put, its innovative point is：Including furnace body, resistance wire, graphite pincers pot and cover board, the furnace body is cylindrical, the furnace body inside
Bottom is provided with graphite pincers pot seat, and the graphite pincers pot is installed on graphite pincers pot seat, and the resistance wire is arranged on furnace body and stone
Between ink pincers pot, the cover board is arranged on the suitable for reading of furnace body, and furnace body top suitable for reading is provided with sealing strip, in the cover board
Gas tube is provided with, the centre of the cover board offers through hole, and stalk, the stalk and cover board are inserted with the through hole
Between sealed using asbestos pad, the top of the cover board sets casting mold.
Further, the furnace body rolls into shape using 5mm iron plates, and inside is tamped using refractory brick.
Further, the sealing strip is asbestos seal bar.
Further, it is provided with gasket between the casting mold and cover board.
The utility model has the advantage of：A kind of metal-mold low-pressure casting sealing device, when air pressure by inflating port into
During row pressurization, whole furnace chamber pressurization, makes molten aluminum enter casting mold by stalk and completes casting, improve load performance, Er Qiejie
Structure is simple.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is a kind of structure diagram of metal-mold low-pressure casting sealing device of the utility model.
