Abstract
The invention discloses a sealing device for a metal mold low-pressure cast lift tube. The sealing device comprises a crucible, a crucible cover and the lift tube. The crucible cover is arranged on the crucible. The lift tube is of a T-shaped structure, perpendicularly penetrates the crucible cover and extends into the crucible. A heating ring is arranged in the upper end of the crucible cover. The lift tube penetrates the heating ring. A gap is formed between the lift tube and the heating ring. A first heat-resistant sliver sealing ring is arranged at the top of the crucible cover. An upper opening of the lift tube is pressed on the first heat-resistant sliver sealing ring. A second heat-resistant sliver sealing ring is arranged between the crucible cover and the crucible. The sealing device is low in cost, high in reliability and convenient to mount; the upper opening of the lift tube is perpendicularly pressed on the first heat-resistant sliver sealing ring; and when the mechanism is jacked upwards, the mechanism is in stable contact with the bottom of a mold to form sealing, in combination with the second heat-resistant sliver sealing ring between the crucible cover and the crucible, the effect that the neck of the lift tube is not pressed and deformed any more can be guaranteed, the service life is prolonged, staff can operate the sealing device conveniently and fast, and working efficiency is improved.
Description
Technical field
The present invention relates to metal-mold low-pressure casting technical field, particularly a kind of metal-mold low-pressure casting stalk sealing device.
Background technology
In metal-mold low-pressure casting, as described in Figure 1, stalk is provided with taper surface to the sealing structure of the stalk of prior art and pot cover, and taper surface is provided with one layer of aluminium silicate pad, stalk is the most salable by upper compression, and suitable for reading the pressing with mould of stalk is closed, intersection recycle silicon acid aluminium backing seals, and stalk top is due to long-term pressurized, and the most heated impact, stalk inside can be caused for a long time to be pressed into drum type, cause stalk length to shorten, until scrapping.
Summary of the invention
It is an object of the invention to provide one can not only increase the service life, and can solve the problem that the metal-mold low-pressure casting stalk sealing device of stalk sealing problem.
The technical solution used in the present invention is:
A kind of metal-mold low-pressure casting stalk sealing device, including pincers pot, pot cover and stalk, described pincers pot is provided with pot cover, described stalk is T-type structure, and extend vertically through in pot cover, extend to clamp inside pot, its innovative point is: be provided with heating collar inside described pot cover upper end, described stalk passes heating collar, and leave gap between the two, the top of described pot cover is provided with the first heat-resisting cotton sliver sealing ring, and the stalk top being pressed in described first heat-resisting cotton sliver sealing ring suitable for reading, it is provided with the second heat-resisting cotton sliver sealing ring between described pot cover and pincers pot.
Further, being provided with and carry out hole inside described pot cover, described air inlet is by internal for pincers pot and ft connection.
Beneficial effects of the present invention is as follows:
Cost of the present invention is relatively low, reliability is high, easy for installation, can not only increase the service life, and can solve the problem that stalk sealing problem；The suitable for reading of stalk is vertically pressed on the first heat-resisting cotton sliver sealing ring, when mechanism upwards pushes up, steadily contact formation to seal with mold bottom, in conjunction with the second heat-resisting cotton sliver sealing ring between pot cover and pincers pot, so can ensure that the cervical region no longer compressive deformation of stalk, improve service life, worker's simple operation, improve work efficiency.
Accompanying drawing explanation
With detailed description of the invention, the present invention is described in further details below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of prior art；
Fig. 2 is the structural representation of the present invention.
Detailed description of the invention
A kind of metal-mold low-pressure casting stalk sealing device as described in Figure 2, including pincers pot 1, pot cover 2 and stalk 3, described pincers pot 1 is provided with pot cover 2, described stalk 3 is T-type structure, and extend vertically through in pot cover 2, extend to clamp pot 1 internal, it is provided with heating collar 4 inside described pot cover 2 upper end, described stalk 3 is through heating collar 4, and leave gap 5 between the two, the top of described pot cover 2 is provided with the first heat-resisting cotton sliver sealing ring 6, and the top being pressed in described first heat-resisting cotton sliver sealing ring 6 suitable for reading of stalk 3, it is provided with the second heat-resisting cotton sliver sealing ring 7 between described pot cover 2 and pincers pot 1, internal being provided with of described pot cover 2 carries out hole 8, described air inlet 8 is by internal for pincers pot 1 and ft connection.
Operation principle is:
The suitable for reading of stalk 3 is vertically pressed on the first heat-resisting cotton sliver sealing ring 6, when mechanism upwards pushes up, steadily contact formation to seal with mold bottom, in conjunction with the second heat-resisting cotton sliver sealing ring 7 between pot cover 2 and pincers pot 1, so can ensure that the cervical region no longer compressive deformation of stalk 3, improve service life, worker's simple operation, improve work efficiency.
The above is the preferred embodiment of the present invention, it is impossible to limit the interest field of the present invention with this.It should be pointed out that, for those skilled in the art, technical scheme is modified or equivalent, without departure from protection scope of the present invention.
Claims (2)
