Description

Raining-type sand filling device

Technical field

The utility model relates to a kind of lost foam casting instrument, particularly a kind of raining-type sand filling device adding sand in evaporative pattern sandbox.

Background technology

Lost foam casting (also known as cavityless casting) is the new technology of a kind of Near net shape, precise forming, this technique is without the need to delivery, without die joint, without core, thus foundry goods does not have overlap, burr and pattern draft, and decreases the scale error caused due to core combination.Surface roughness can reach Ra3.2 to 12.5 μm; Casting dimension accuracy can reach CT7 to 9; Allowance mostly is 1.5 to 2mm most, can greatly reduce the expense of machining, compares with traditional sand mould casting method, between the machining that can reduce 40% to 50%.Lost foam casting process: first, bonds the paraffin similar to casting dimension shape or bubbles model and is combined into model cluster, brushes fireproof coating and dries; Secondly, be placed in sandbox by model cluster, and in sandbox, pour quartz sand into model cluster circumference buried, pour into a mould under negative pressure, model is gasified, and liquid metals occupies modal position, forms foundry goods after solidifying cooling.The work importing quartz sand in sandbox is completed by raining-type sand filling device, sand after raining-type sand filling device like rain as fall in sandbox, according to the flow difference of the sand that different models flows out through raining-type sand filling device, but existing sand Flow-rate adjustment completes by entering sand system, and equipment is complicated, cost is high.

Utility model content

In view of this, the technical problems to be solved in the utility model is to provide a kind of raining-type sand filling device, can adjust sand flow amount and equipment is simple.

Raining-type sand filling device of the present utility model, comprise the casing of bottom opening, lay respectively at first in casing and leak sand plate and second and leak sand plate, described first leaks the top that sand plate is positioned at the second leakage sand plate, and the first leakage sand plate and second leaks on sand plate and is evenly equipped with multiple sand losing opening respectively; Described first leaks sand plate coordinates with casing horizontal slip, described first leaks sand plate makes it leak sand plate leakage sand hole between the two and communicate with second up and down or close by the air cylinder driven be positioned at outside casing, described second leaks sand plate both sides is fixedly connected with coaxial bearing pin, and described bearing pin and box side are rotatably assorted.

Further, the part that described bearing pin is positioned at outside casing is radially provided with driving lever, described driving lever is provided with the slide bar with its axial sliding fit, described slide bar is axially parallel with bearing pin, the outer coaxial sleeve of described bearing pin has annular slab, described annular slab circumference is evenly equipped with multiple elongated hole radially extended by its periphery, and described slide bar can pass in and out each elongated hole.

The beneficial effects of the utility model: raining-type sand filling device of the present utility model, comprise the casing of bottom opening, lay respectively at first in casing and leak sand plate and second and leak sand plate, described first leaks the top that sand plate is positioned at the second leakage sand plate, and the first leakage sand plate and second leaks on sand plate and is evenly equipped with multiple sand losing opening respectively; Described first leaks sand plate coordinates with casing horizontal slip, described first leaks sand plate makes it leak sand plate leakage sand hole between the two and communicate with second up and down or close by the air cylinder driven be positioned at outside casing, described second leaks sand plate both sides is fixedly connected with coaxial bearing pin, and described bearing pin and box side are rotatably assorted.Second leaks sand plate adjustable angle, makes its horizontal projected area of leaking sand hole adjustable, and then can adjust its leakage sand flow amount, and structure is simple, easy to operate.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further described.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the partial enlarged view of A in Fig. 1;

Fig. 3 is that schematic diagram is looked on the right side of Fig. 2.

Detailed description of the invention

Below with reference to accompanying drawing, the utility model is described in detail, as shown in the figure: the raining-type sand filling device of the present embodiment, be positioned at during work above sandbox, comprise the casing 1 of bottom opening, lay respectively at first in casing and leak sand plate 2 and second and leak sand plate 3, described first leaks the top that sand plate 2 is positioned at the second leakage sand plate 3, and the first leakage sand plate 2 and the second leakage sand plate 3 are evenly equipped with multiple sand losing opening 4 respectively; Described first leaks sand plate 2 coordinates with casing 1 horizontal slip, described first leaks sand plate 2 is driven by the cylinder 5 be positioned at outside casing and makes it leak sand plate leakage sand hole about 4 between the two and communicate with second or close, when needs are to the time of falling sand in sandbox, cylinder 5 drives that the first leakage sand plate is traversing makes it leak sand plate 3 sand losing opening about 4 be between the two communicated with second, to leak sand, leakage sand terminates exhaust hood and drives traversing itself and the second leakage sand plate 3 sand losing opening about 4 between the two of making of the first leakage sand plate to interlock closed again.In order to Lou sand flow amount can be adjusted, described second leaks sand plate 3 both sides is fixedly connected with coaxial bearing pin 6, described bearing pin 6 is rotatably assorted with casing 1 side plate, when first leaks sand plate 2 and the second leakage sand plate 3 leakage sand hole is between the two communicated with up and down, rotating pin 6 makes the second leakage sand plate 3 together rotate, the horizontal projected area of the leakage sand hole on the second leakage sand plate 3 is changed, the sand that the sand losing opening leaked sand plate 2 from first like this flows out flow when through the second leakage sand hole 3 changes, and can regulate Lou sand flow amount easily.

As the further improvement of technique scheme, the part that described bearing pin 6 is positioned at outside casing is radially provided with driving lever 7, described driving lever 7 is provided with the slide bar 8 with its axial sliding fit, described slide bar 8 is axially parallel with bearing pin 6, the outer coaxial sleeve of described bearing pin 6 has annular slab 9, annular slab 9 is fixedly connected with on cabinet exterior, multiple elongated hole 10 radially extended by its periphery is evenly equipped with in described annular slab 9 circumference, described slide bar 8 can pass in and out each elongated hole 10, so just bearing pin 6 circumference can be fixed on different positions, and then make the second leakage sand plate be in different angles of inclination.

What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
