Description

A kind of moltening mold castings push-down sand spraying apparatus

Technical field

This utility model belongs to model casting field, is specifically related to a kind of moltening mold castings push-down sand spraying apparatus。

Background technology

When the manufacture of the machine components of some complex precises or thin-walled of carrying out automobile, often use conventional methods the low or prepared element precision of ratio of briquetting not high, casting for this part is generally adopted model casting, the shape of investment-casting is general all more complicated, on foundry goods, the castable minimum diameter portalled is up to 0.5mm, and the minimum wall thickness (MINI W.) of foundry goods is 0.3mm。By some originally by the parts of several part combination, by changing the structure of part, one-piece parts can be designed to and directly cast out by model casting, to save the consumption of machining period and metal material, make design of part more reasonable aborning。Model casting, also known as lost-wax casting, including pressure wax, is repaiied wax, group tree, is stained with slurry, sands, the operation such as dewaxing, casting metals liquid and post processing。Lost-wax casting is the wax-pattern casting part with waxed work, is then coated with mud on wax-pattern, then sprinkles the sand that thick layer is thick, finally carries out roasting in being put into heating furnace, and wax-pattern all melts loss, only surplus Tao Mo。In the process sanded, generally require and allow the sand enclosed on mud reach 5-7mm, the method adopted at present is to adopt manual type, namely wax-pattern is moved to below husky frame by fixing bar by workman, then do not stop to stir wax-pattern, until the husky thickness enclosed suitable after, enter back into next step operation, this method labor efficiency is low, adds the work burden of workman。

Utility model content

For above-mentioned prior art, this utility model aims to provide a kind of moltening mold castings push-down sand spraying apparatus, and this apparatus structure is simple, it is possible to drive wax-pattern constantly to rotate in the process sanded so that sand is uniform fold on wax-pattern。

In order to achieve the above object, the technical solution of the utility model is a kind of moltening mold castings push-down sand spraying apparatus, it is characterized in that, including have some fine and closely woven fall husky hole the husky frame that falls, described fall husky frame fixed by supporting leg, it is additionally provided with the husky frame of collection below, described fall husky frame side be additionally provided with a fixed station, described fixed station is provided with riser, described riser is also hinged with a plate, described connecting plate is fixedly connected with rotary electric machine, the motor bar of described rotary electric machine is provided with in order to the connecting hole with the fixing bar connection of wax-pattern, described fixed station is additionally provided with a push rod device, the push rod of described push rod device contacts through riser and with described connecting plate。

Further, being provided with articulated joint in the middle part of described riser, described riser is hinged by articulated joint and connecting plate, described riser and connecting plate in parallel between be separated with distance。

Further, described push rod device is push-rod electric machine。

The beneficial effects of the utility model: this apparatus structure is simple, it is possible to drive wax-pattern constantly to rotate in the process sanded so that sand is uniform fold on wax-pattern。

Accompanying drawing explanation

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings。

Fig. 1 is structural scheme of mechanism of the present utility model。

In figure: 1, fall husky frame；2, supporting leg；3, the husky frame of collection；4, fixed station；5, riser；6, wax-pattern；7, fixing bar；8, connecting plate；9, rotary electric machine；10, connecting hole；11, push rod；12, push-rod electric machine。

Detailed description of the invention

This utility model is further described below in conjunction with specific embodiment and accompanying drawing。

A kind of moltening mold castings push-down sand spraying apparatus as shown in Figure 1, including have some fine and closely woven fall husky hole the husky frame 1 that falls, described fall husky frame 1 fixed by supporting leg 2, it is additionally provided with the husky frame 3 of collection below, described fall husky frame 1 side be additionally provided with a fixed station 4, described fixed station 4 is provided with riser 5, described riser 5 is also hinged with a plate 8, described connecting plate 8 is fixedly connected with rotary electric machine 9, the motor bar of described rotary electric machine 9 is provided with in order to fix, with wax-pattern 6, the connecting hole 10 that bar 7 connects, described fixed station 4 is additionally provided with a push rod device, the push rod 11 of described push rod device contacts through riser 5 and with described connecting plate 8。

Further, being provided with articulated joint in the middle part of described riser 5, described riser 5 is hinged by articulated joint and connecting plate 8, described riser 5 and connecting plate 8 in parallel between be separated with distance。

Further, described push rod device is push-rod electric machine 12。

This utility model process when in use is as follows, when wax-pattern 6 is after a upper operation encloses mud, the fixing bar 7 of wax-pattern 6 is connected on the motor bar of motor, it is (corresponding owing to motor bar being provided with connecting hole 10, the fixing bar 7 of wax-pattern 6 is also equipped with connecting hole 10), so screw bolt and nut can be passed through by the two fixing connection, after connection completes, sand is loaded above the husky frame 1 that falls, owing to being provided with the fine and closely woven husky hole that falls bottom the husky frame 1 that falls, so sand will constantly drop, now start rotary electric machine and push rod device, rotary electric machine drives wax-pattern 6 to start to rotate, then sand just covers on the mud of wax-pattern 6, meanwhile, because connecting plate 8 is hinged on riser 5, so push rod device can constantly promote connecting plate 8 ceaselessly to swing when elongation and contraction, that is, wax-pattern 6 is also ceaselessly swinging while rotating, so sand can uniformly be attached on wax-pattern 6, and substantially can guarantee that what sand do not have a dead angle is attached on wax-pattern 6, the sand being not adhered on wax-pattern 6 can be collected by the husky frame 3 of collection being wherein arranged below, recycle。This utility model riser 5 and connecting plate 8 can also adopt other modes to be hinged, and such as connecting plate 8 is hinged by hinge structure and riser 5, and wherein push rod device can adopt push-rod electric machine 12 can also adopt push rod cylinder。

The technical scheme above this utility model embodiment provided is described in detail, principle and the embodiment of this utility model embodiment are set forth by specific case used herein, and the explanation of above example is only applicable to the principle helping to understand this utility model embodiment；Simultaneously for one of ordinary skill in the art, according to this utility model embodiment, all will change in detailed description of the invention and range of application, in sum, this specification content should not be construed as restriction of the present utility model。
