Description
Technical field
This utility model is related to precision casting technology field, more particularly, to a kind of hot investment casting dustproof construction.
Background technology
Precision-investment casting, is an excellent Technology in casting industry, and its application is widely.It is applied to
All kinds, the casting of various alloy, the casting dimension accuracy produced is high, surface quality is good, is particularly suited for casting temperature
Height, casting structure are complicated, be not easy to the foundry goods of processing.But in hot investment casting production process, usually due to molten steel, the stove of splashing
Interior dust is fallen in formwork, makes whole foundry goods existing defects, does not reach the prescription of foundry goods.
In the technology disclosed in hot investment casting dust guard of Patent No. 201220247859.9, using rustless steel dust cap
Realize rustless steel dust cap with cylinder cooperation to move horizontally, upper cast gate is sealed, so rustless steel dust cap level is moved
Dynamic requirement for height accurately, produces metal expulsion point in process of production due to above pouring discharge surface, leads to its surface irregularity, make
Rustless steel dust cap can not effectively seal to upper cast gate, may affect normally to produce when serious.
Content of the invention
The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of hot investment casting dust-proof knot
Structure is it is ensured that the sealing effectiveness of upper cast gate.
This utility model solves its technical problem and be employed technical scheme comprise that：
A kind of hot investment casting dustproof construction, including upper cast gate, connecting rod, hydraulic stem and dust cover it is characterised in that：Institute
The dust cover stated cover upper pour discharge surface setting and its edge is slightly larger than cast gate edge of opening, dust cover includes housing
With the three-back-shaped dust excluding plate being arranged within housing, three-back-shaped dust excluding plate is obliquely installed and three-back-shaped dust excluding plate bottom is provided with upward
Flange, overlapping 0.5-1cm setting between adjacent three-back-shaped dust excluding plate, connecting rod one end is connected with dust cover by fixture
Fixing, the connecting rod other end is rotated with an installed surface and is connected, and hydraulic stem one end is rotated with connecting rod bottom and is connected, and hydraulic stem is another
End is rotated with described installed surface and is connected.
In sum, this utility model has the advantages that：Reasonable in design, makes dust cover pass through rotation
Mode seals cast gate, is not affected by upper cast gate surface roughness, and simultaneously dust-proof, splashproof effect is good, has ensured normal life
Produce.
Brief description
With reference to the accompanying drawings and examples this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of dust cover.
Fig. 3 is the cross-sectional view of " A-A " in Fig. 2.
In figure, cast gate on 1,2 dust covers, 3 fixtures, 4 connecting rods, 5 hydraulic stems, 6 installed surfaces, 7 housings, 8 three-back-shaped anti-
Dirt plate, 9 flange.
Specific embodiment
Hereinafter embodiment of the present utility model is illustrated by particular specific embodiment, those skilled in the art can be by this
Content disclosed by description understands other advantages of the present utility model and effect easily.
With reference to the accompanying drawings shown in 1,2,3：This utility model provides a kind of hot investment casting dustproof construction, including upper cast gate 1, even
Extension bar 4, hydraulic stem 5 and dust cover 2, described dust cover 2 covers in the setting of upper cast gate 1 surface and its edge is slightly larger than and pours
Mouth 1 edge of opening, makes dust cover 2 can upper cast gate 1 be realized covering comprehensively, and dust cover 2 includes housing 7 and is arranged on
Three-back-shaped dust excluding plate 8 within housing 7, the space between three-back-shaped dust excluding plate 8 is used for the discharge of waste gas in molten steel, also may be used simultaneously
Fall in formwork with the molten steel preventing from splashing, three-back-shaped dust excluding plate 8 is obliquely installed and three-back-shaped dust excluding plate 8 bottom is provided with upward
Flange 9, can be stopped to the dust falling on three-back-shaped dust excluding plate 8 surface by the setting of flange 9, prevent dust from falling into
Cast gate 1, between adjacent three-back-shaped dust excluding plate 8, overlapping 0.5-1cm setting, ensures sealing and dust-proof effect, connecting rod 4 one end leads to
Cross fixture 3 to be connected with dust cover 2, connecting rod 4 other end and an installed surface 6 rotate and be connected, hydraulic stem 5 one end be connected
Bar 4 bottom rotates and connects, and the rotation of hydraulic stem 5 other end and described installed surface 6 is connected, can also be according to the environment in body of heater
Protective housing is installed in hydraulic stem 5 outside, ensures the normal use of hydraulic stem 5, installed surface 6 is inboard wall of furnace body, by connecting rod 4 He
The rotation of dust cover 2 is realized in the cooperation of hydraulic stem 5.
The foregoing is only preferred embodiments of the present utility model, as long as realizing this utility model with essentially identical means
Purpose technical scheme, broadly fall within protection domain of the present utility model.
