Description
Technical field
The utility model relates to the manufacturing equipment field of sintered NdFeB, is specifically related to a kind of Sintered NdFeB magnet magazine.
Background technology
Along with the development of science and technology, current neodymium iron boron rare earth permanent magnet device plays an important role in each electronic product as indispensable electronic component.The main production process of sintered NdFeB comprises that batching, melting, hydrogen are broken, airflow milling, isostatic pressed, forming and sintering etc.NdFeB material is in sintering desaeration process, and shrink due to product densification and have a large amount of gas to release simultaneously, if sintering box is closed at that time, then gas cannot be taken away by vacuum pump in time, and product then there will be cracking phenomena at interface; If before sintering, magazine is closed not, then product is easy to contact with air and be oxidized.
Utility model content
(1) technical problem that will solve
It is simple that the technical problems to be solved in the utility model is to provide a kind of structure, is convenient to exhaust and not oxidizable Sintered NdFeB magnet magazine.
(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of Sintered NdFeB magnet magazine, it comprises box body and is arranged on the lid above box body, box body is provided with the cavity volume of upper opening, the below of lid offers the location notch matched with box body, box body offers the air vent hole be connected with cavity volume, air vent hole is provided with plug.
Wherein, one end of plug is provided with the locating ring being resisted against box body outer wall.
Wherein, box body is installed with guide rod, locating ring offers guide hole, one end of guide rod is through guide hole.
Wherein, the other end of guide rod is provided with locating piece.
Wherein, the internal diameter of guide hole is greater than the external diameter of guide rod.
Wherein, the below of box body is provided with projection, and projection matches with the cavity volume of another box body.
Wherein, the top of lid offers the groove matched with projection.
(3) beneficial effect
Compared with prior art, the utility model, by arranging air vent hole, makes the air in ground cavity volume be emptied completely, and is provided with plug on air vent hole, and the phenomenon be oxidized occurs to avoid sintering front neodymium iron boron green compact and contacting external air.

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but can not be used for limiting scope of the present utility model.
The stereochemical structure of the utility model Sintered NdFeB magnet magazine as shown in Figure 1, its horizontal section structure as shown in Figure 2, the lid 2 that this Sintered NdFeB magnet magazine comprises box body 1 and is arranged on above box body 1, box body 1 is provided with the cavity volume 11 of upper opening, the below of lid 2 offers the location notch 21 matched with box body 1, box body 1 offers the air vent hole 12 be connected with cavity volume 11, air vent hole 12 is provided with plug 3, this air vent hole 12 is multiple, improves exhaust velocity.
One end of above-mentioned plug 3 is provided with the locating ring 31 being resisted against box body 1 outer wall, is convenient to locate plug.
Box body 1 is installed with guide rod 4, locating ring 31 offers guide hole 32, one end of guide rod 4, through guide hole 32, when plug being installed or departs from, makes it carry out along guide rod.
The other end of guide rod 4 is provided with locating piece 41, avoids plug to depart from to guide rod, and causes the loss of plug.
The internal diameter of guide hole 32 is greater than the external diameter of guide rod 4, when plug is departed from from air vent hole, can rotate around center of pilot, makes its complete Opening Ventilation hole, as shown in Figure 3.
The below of box body 1 is provided with projection 13, and projection 13 matches with the cavity volume 11 of another box body 1, when making sintering, can by stacked for multiple box body placement, and the box body on upper strata can be avoided to slide.
The top of lid 2 offers the groove 22 matched with projection 13, before sintering, also can be placed on stacked for other magazines on another magazine.
Above-mentioned box body, lid, plug and guide rod are made by graphite material.
In exhaust process, due to the pressure differential inside and outside box body, force plug to depart from from air vent hole, the gas of tray interior is discharged, and before sintering, only plug need be mounted on air vent hole.The utility model, by arranging air vent hole, makes the air in ground cavity volume be emptied completely, and is provided with plug on air vent hole, and the phenomenon be oxidized occurs to avoid sintering front neodymium iron boron green compact and contacting external air.
These are only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
