Abstract
The invention relates to a vacuumizing device for foundry casting. The vacuumizing device comprises a box body, wherein the box body is enclosed by a bottom plate and side plates arranged on the bottom plate; a high-temperature-resisting thin film is arranged at the top of the box body; channel steel is arranged at the peripheries of the outer walls of the side plates and grooves in the channel steel are communicated mutually; an air channel is formed between each groove and each side plate; the channel steel is provided with an exhausting opening communicated with each air channel; a plurality of air passing holes are formed in each side plate by corresponding to the grooves of the channel steel; a filtering net is arranged along the periphery of the inner wall of each side plate by corresponding to the channel steel; each filtering net is provided with a pressing plate; the width of each pressing plate is not less than that of each groove of the channel steel; each pressing plate is provided with air outlets corresponding to the air passing holes in each side plate. According to the vacuumizing device for the foundry casting, the manpower cost is reduced and the production efficiency is improved.
Description
Technical field
The present invention relates to foundry casting field, refer to especially a kind of vacuum extractor for foundry casting.
Background technology
Founding is that molten metal is poured in casting mold cavity, obtains the production method of product after cooled and solidified.Its operation generally comprises: mulling operation, moulding operation, melting operation, cast operation, cleaning process, wherein, the general flow of moulding operation is: model one moulding one (coremaking is core once) mould assembling one cast.In moulding operation, ready-made mould need be put into sandbox, then with sand, fill up sandbox, and the sand reality of pounding, at present, ramming adopts manual operation mostly, need expend more manpower, efficiency is lower, and cost is higher.And if manual operation firmly not, sand mold is too loose, easily crush.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of efficiency higher, the lower-cost vacuum extractor for foundry casting, this device can solve because of the too loose problem that causes crush of sand mold.
For addressing the above problem, the technical solution used in the present invention is: a kind of vacuum extractor for foundry casting, comprise casing, this casing is by base plate and be arranged on side plate on base plate and crowd around and form, described casing top is provided with high-temperature resistant membrane, along side plate outer wall, within one week, be provided with channel-section steel, groove on channel-section steel connects mutually, and form air flue with side plate, on channel-section steel, offer the bleeding point communicating with this air flue, on described side plate, facing to channel-section steel groove, offer several air passing holes, along side plate inwall, within one week, on the position corresponding with channel-section steel, be provided with filter screen, on filter screen, be provided with pressing plate, the width of pressing plate is not less than the width of channel-section steel groove, and on pressing plate, be provided with the venthole corresponding with air passing hole on side plate.
As a kind of preferred version, described channel-section steel is arranged on the centre position of casing.
As a kind of preferred version, described filter screen >=70 order.
As a kind of preferred version, described casing is square.
As a kind of preferred version, described bottom half is provided with at least four wheels.
The invention has the beneficial effects as follows: above-mentioned a kind of vacuum extractor for foundry casting is respectively arranged with venthole and air passing hole on pressing plate and box side, air between sand grains in casing can be extracted out by bleeding point, improved the packing of sand, make sand mold closely knit, be difficult for crush, and, reduced human cost, improved production efficiency.In addition, owing to channel-section steel being arranged on to the centre position of casing, can the air in casing be taken out more thoroughly, make in casing the density of sand more even, further improve the packing of sand, make sand mold more closely knit; In addition, be arranged on the wheel of bottom half, greatly facilitate the movement of casing, reduced labour intensity; Due to filter screen >=70 order adopting, effectively avoided sand grains to be sucked out from air passing hole.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of vacuum extractor for foundry casting of the present invention.
In figure: 1, casing, 2, base plate, 3, side plate, 4, high-temperature resistant membrane, 5, channel-section steel, 6, air flue, 7, bleeding point, 8, air passing hole, 9, filter screen, 10, pressing plate, 11, venthole, 12, wheel.
The specific embodiment
Below by specific embodiment, a kind of vacuum extractor for foundry casting of the present invention is described in further detail.
As shown in Figure 1, a kind of vacuum extractor for foundry casting, comprise square box 1, this casing 1 is by base plate 2 and be arranged on side plate 3 on base plate 2 and crowd around and form, described casing 1 top is provided with high-temperature resistant membrane 4, along side plate 3 outer wall, within one week, be provided with channel-section steel 5, channel-section steel 5 is arranged on the centre position of casing 1, groove on channel-section steel 5 connects mutually, and form air flue 6 with side plate 3, on channel-section steel 5, offer the bleeding point 7 communicating with this air flue 6, on described side plate 3, facing to channel-section steel 5 grooves, offer several air passing holes 8, along side plate 3 inwall, within one week, on the position corresponding with channel-section steel 5, be provided with 70 object filter screens 9, on filter screen 9, be provided with pressing plate 10, the width of pressing plate 10 is not less than the width of channel-section steel 5 grooves, and on pressing plate 10, be provided with the venthole 11 corresponding with air passing hole 8 on side plate 3, described casing 1 bottom is provided with four wheels 12.
During use, the bleeding point of evacuator is received on bleeding point 7, then, started evacuator, the air between the sand grains in casing 1 is by continually from bleeding point 7 ground sucking-offs.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not for limiting the present invention; It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
