Abstract

The utility model discloses a rectangular die for neodymium-iron-boron materials. The rectangular die comprises a die body and an upper pressure plate (6), wherein die body consists of a left side plate (1), a right side plate (2), a front baffle (3), a rear baffle (4) and a lower bottom plate (5). The left side plate (1), the front baffle (3), the right side plate (2) and the rear baffle (4) are successively connected to form a rectangular frame; and the lower bottom plate is connected with the bottom end of the rectangular frame. The die body also comprises a clapboard (7) which is parallel to the left side plate (1) and right side plate (2) and respectively connected with the front baffle (3) and rear baffle (4), thus the die body is equally divided into two cavity bodies (8); and the middle of the upper pressure plate (6) is provided with a groove (9) which is matched with the clapboard (7) in size. The rectangular die for neodymium-iron-boron materials can product two round products in a processing cycle.

Description

The NdFeB material rectangular mould

Technical field

The utility model relates to a kind of mould, is specifically related to a kind of rectangular mould that is used for the NdFeB material moulding.

Background technology

At present, the rectangle finished product of China's NdFeB material mainly carries out moulding by the unidirectional compacting of mould, mould generally comprises die body and the top board that is made of left plate, right plate, front apron, backboard and lower shoe, left plate, right plate, front apron, backboard join and surround rectangle frame, lower shoe and rectangle frame bottom join and form the die body of an open-top, with the NdFeB material fine powder die body of packing into, after being orientated, top board is placed on die body and carries out compacting, make the rectangle finished product.But there is following defective in the rectangular mould of this NdFeB material in the production process of reality: this existing mold can only be produced a rectangle finished product in a process-cycle, so the production efficiency of this rectangular mould is low.

The utility model content

Technical problem to be solved in the utility model is at above the deficiencies in the prior art, and a kind of NdFeB material rectangular mould that can produce two rectangle finished products in a process-cycle is provided.

For addressing the above problem, the utility model provides a kind of NdFeB material rectangular mould to comprise die body and the top board that is made of left plate, right plate, front apron, backboard and lower shoe, left plate, front apron, right plate, backboard connect successively and surround rectangle frame, lower shoe is connected with the rectangle frame bottom, described die body also comprises a dividing plate, described dividing plate and left plate, right plate is parallel and be connected with front apron, backboard respectively, die body is divided equally into two cavitys, groove is arranged one, groove size dimension and dividing plate coupling in the middle of the described top board.

After adopting above structure, the utility model compared with prior art, have the following advantages: this NdFeB material rectangular mould is by left plate, front apron, right plate, backboard and lower shoe are assembled into the die body of an open-top, it is two cavitys that being provided with of dividing plate divided the inner chamber of die body equally, and the top board centre has groove one, when top board is pressed into die body, dividing plate snaps in the groove, compacting process is carried out smoothly, in a process-cycle, can produce two rectangle finished products that specification is identical like this, therefore the use of the utility model NdFeB material rectangular mould is not only time saving and energy saving, and the production efficiency height.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model NdFeB material rectangular mould comprises die body and the top board 6 that is made of left plate 1, right plate 2, front apron 3, backboard 4 and lower shoe 5, left plate 1, front apron 3, right plate 2, backboard 4 connect successively and surround rectangle frame, be specially front apron 3, backboard 4 and insert the draw-in groove 10 that left plates 1, right plate 2 inboards preset, lower shoe and rectangle frame bottom are connected to form the die body of an open-top.

Described die body also comprises a dividing plate 7, and described dividing plate 7 and left plate 1, right plate 2 are parallel and be connected with front apron 3, backboard 4 respectively, and die body is divided equally into two cavitys 8.Front apron 3, the backboard 4 inboard middle draw-in grooves 10 that preset are inserted in the two ends that concrete connected mode is a dividing plate 7.

Described top board 6 is thick rectangular plates, and the size of square-section (long with wide) is identical with the sectional dimension (long and wide) of the internal cavity that the rectangle frame of die body forms.The centre that in the middle of the top board 6 is the thick rectangular plate lower surface has groove 9 one, size dimension of groove 9 (length of groove 9, width, highly) and dividing plate 7 (length of dividing plate 7, thickness, the degree of depth) coupling.Groove 9 is parallel with dividing plate 7, and when top board 6 covered on die body, dividing plate 7 snapped in the groove 9, and top board 6 can be continued toward pressing down, up to the compacting of NdFeB material fine powder.

Above embodiment is to explanation of the present utility model and further explains, rather than to restriction of the present utility model, any modification of being done in interest field of the present utility model all falls into protection domain of the present utility model.
