The vaccum casting mold is simple in structure and novel in design, casting quality is high, equipment is easy to maintain, and the vaccum casting mold has practicability.

Description

The vacuum pressing and casting mould
Technical field
The utility model belongs to field of metal casting technology, is specifically related to a kind of vacuum pressing and casting mould.
Background technology
Casting is one of fundamental technology of modern mechanical manufacturing industry.Casting is Metal Melting to be smelt meet necessarily required liquid and water in casting mold, obtains the technical process of the foundry goods of reservation shape, size and performance through cooled and solidified, after leveling processing.The casting blank is shaped because being close to, and has reduced cost and has reduced the time to a certain extent and reach the purpose of exempting from machining or a small amount of processing.
At present in casting technique, for the complicated foundry goods of shape, can be full of formwork fully and avoid occurring defective products for guaranteeing to water material, need to place special installation to vibrate or whipping formwork, to form qualified foundry goods.Be provided with vibration and the equipment of the whipping high but also complex structure that not only consumes energy.
The utility model content
The technical problem that (one) will solve
The technical problems to be solved in the utility model provides a kind of vacuum pressing and casting mould, and it is simple in structure, and is easy and simple to handle, and casting quality is high.
(2) technical scheme
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of vacuum pressing and casting mould, comprise a housing (3) and evacuator (7), described housing (3) comprises sandbox chamber (2) and vacuum chamber (10), described sandbox chamber (2) and vacuum chamber (10) separate with the first metal sand net (8), it is upper and fixing with refractory seals pad (4) that described the first metal sand net (8) is fixed on described housing (3), also be provided with the second metal sand net (6) in the described vacuum chamber (10), described the second metal sand net (6) is positioned at the first metal sand net (8) below, and the suction opeing of described evacuator (7) is located at described housing (3) bottom.
Described housing (3) sidewall that is positioned between the first metal sand net (8) and the second metal sand net (6) is provided with an opening (9), and the sealing-plug suitable with it (5) is housed on the described opening (9).
(3) beneficial effect
The utility model is compared to prior art, and it has following beneficial effect: it is simple in structure, modern design, and casting quality is high, and equipment is easy to safeguard, has practicality.
Description of drawings
Fig. 1 is the structural representation of vacuum pressing and casting mould of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
A kind of vacuum pressing and casting mould as shown in Figure 1, comprise a housing 3 and evacuator 7, housing 3 comprises sandbox chamber 2 and vacuum chamber 10, sandbox chamber 2 and vacuum chamber 10 usefulness the first metal sand net 8 separate, the first metal sand net 8 is fixed on the housing 3 and with refractory seals pad 4 and fixes, also be provided with the second metal sand net 6, the second metal sand nets 6 in the vacuum chamber 10 and be positioned at the first metal sand net 8 belows, the suction opeing of evacuator 7 is located at housing 3 bottoms.The mesh diameter of the first metal sand net is less than the diameter of sand, and the mesh diameter of the second metal sand net is less than the first metal sand net, and like this double filtration can be played the effect of protection evacuator.
Housing 3 sidewalls between the first metal sand net 8 and the second metal sand net 6 are provided with an opening 9, are equipped with on the opening 9 and its suitable sealing-plug 5, behind the end-of-job, open sealing-plug, can clear up the metal sand net, guarantee that sand net mesh does not stop up.
The utility model is simple in structure, modern design, and casting quality is high, and equipment is easy to safeguard, has practicality.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
