Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses a mould for producing diamond grinding wheel. Referring to fig. 1 and 2, a mould for producing diamond grinding wheel is including being the massive bed die 1 of cylinder, bilateral symmetry at bed die 1 is provided with a pair of massive clamp plate 2 that is the cylinder, two clamp plates 2 use with the cooperation of bed die 1, and the axis of clamp plate 2 and the axis coincidence of bed die 1, holding tank 11 has been seted up to the symmetry on the surface of bed die 1's both sides, when producing and processing diamond grinding wheel, holding tank 11 is inside to be used for filling the diamond raw materials, then through two clamp plates 2 of press drive, make clamp plate 2 can compress tightly on bed die 1, thereby the rudiment shape of suppression diamond grinding wheel, and make diamond grinding wheel shaping gradually through subsequent step.

At two clamp plates 2 towards bed die 1 on the surface homogeneous body shaping be provided with circular platelike briquetting 21, briquetting 21 coincides with the centre of a circle of clamp plate 2, when suppressing diamond grinding wheel, briquetting 21 can peg graft and cooperate inside holding tank 11, briquetting 21 global and holding tank 11's cell wall laminate mutually, peg graft inside back of holding tank 11 completely when briquetting 21, clamp plate 2 laminates mutually with bed die 1, when suppressing diamond grinding wheel, the briquetting 21 of setting is under the effect that receives the pressure of press, the better is more closely knit with the inside diamond feedstock suppression of holding tank 11, and compress tightly through briquetting 21 makes diamond grinding wheel reach certain intensity.

Two holding tanks 11 that set up on bed die 1 and the clamp plate 2 and the briquetting 21 that cooperate holding tank 11 to set up, when producing diamond grinding wheel, can once only process out two diamond grinding wheels through a bed die 1, improved the efficiency of production diamond grinding wheel.

Further, the depth of holding tank 11 is greater than the thickness of briquetting 21 all the time to the distance between holding tank 11 tank bottom surface and the relative briquetting 21 surface remains throughout fixed, avoids changing, when this mould repetitious usage suppressed the diamond grinding wheel, can make the diamond grinding wheel who presses out from beginning to end remain fixed thickness all the time, has also guaranteed the precision of diamond grinding wheel simultaneously.

Referring to fig. 1, 2 and 3, two central grooves 12 are symmetrically formed in the female die 1 at the positions of the centers of the bottoms of the two accommodating grooves 11, the axes of the two central grooves 12 coincide with the axis of the female die 1, the core dies 3 are mounted in the two central grooves 12, the core dies 3 are of a cylindrical structure, and the core dies 3 can be inserted into the central grooves 12 when the diamond grinding wheel is pressed; the center positions of the pressing plate 2 and the pressing block 21 are provided with through center holes 22, one end of the core mold 3, which is far away from the female mold 1, penetrates out of the center holes 22, and the core mold 3, the pressing plate 2 and the pressing block 21 slide mutually, so that when the diamond grinding wheel is produced, the set core mold 3 can reserve a reserved hole in the center position of the diamond grinding wheel, and the produced diamond grinding wheel can be better installed on equipment for driving the diamond grinding wheel to rotate; when pressing the diamond grinding wheel, the worker installs mandrel 3 in central groove 12 earlier, then fills the holding tank 11 with the diamond raw materials in, establish clamp plate 2 and briquetting 21 cover on mandrel 3 to make briquetting 21 can correspond and peg graft in holding tank 11, place this mould on the press at last, make the press can apply pressure to clamp plate 2 gradually, until the shaping of diamond grinding wheel.

The core mold 3 is made of electrode graphite, the electrode graphite has crisp property, when the diamond grinding wheel is processed, the core mold 3 is disposable, when the diamond grinding wheel is pressed, a worker breaks the core mold 3, then the pressing plate 2 is taken down from the female mold 1, finally the pressed diamond grinding wheel is taken down, and when the next diamond grinding wheel pressing is carried out, a new core mold 3 is installed on the female mold 1 again.

Referring to fig. 1, 2 and 3, a connecting hole 13 is formed in the female die 1 and located at the center of the bottom of the two central grooves 12, the two central grooves 12 are communicated through the connecting hole 13, and when a worker needs to take the diamond grinding wheel off the female die 1, if the core die 3 is cracked and inconvenient to take out of the core die in the central groove 12 on one side, the worker can clean the two central grooves 12 through the central hole 22, so that the diamond grinding wheel is prevented from being pressed next time.

Further, bed die 1, clamp plate 2 and briquetting 21 are made by the graphite material that excels in, the graphite material that excels in has the characteristic that intensity is high, when suppression diamond grinding wheel, can avoid the press to crush bed die 1, clamp plate 2 and briquetting 21, and bed die 1 by the graphite that excels in is made, clamp plate 2 and briquetting 21 are when suppressing cubic diamond grinding wheel, three can have not the fish tail of equidimension on the surface, for avoiding the fish tail to influence the precision of suppressing diamond grinding wheel, the staff can carry out lathe work to bed die 1 and briquetting 21 and 2 complex surfaces of clamp plate again, make its surface can be more smooth and clean.

When the female die 1, the pressing plate 2 and the pressing block 21 are processed, the parallelism of the groove bottom surfaces of the two accommodating grooves 11 on the female die 1 is 0.01, the parallelism of the surfaces of the two pressing blocks 21 far away from the pressing plate 2 is also kept at 0.01, and the parallelism between the two opposite surfaces of the accommodating grooves 11 and the pressing blocks 21 is kept, so that the pressed diamond grinding wheel can be always kept at high precision, and the surface of the pressed diamond grinding wheel is prevented from being uneven.

The implementation principle of the mold for producing the diamond grinding wheel in the embodiment of the application is as follows: when the diamond grinding wheel needs to be produced, an operator firstly installs the two core moulds 3 into the central groove 12 correspondingly, then fills diamond raw materials into the accommodating groove 11, then installs the pressing plate 2 on the core mould 3 in a sleeved mode, finally installs the mould on a press machine, applies pressure to the pressing plate 2 through the press machine to enable the diamond grinding wheel to be gradually formed in the accommodating groove 11, and when the diamond grinding wheel needs to be removed from the female mould 1 after being pressed, the operator breaks the core mould 3, then removes the pressing plate 2 and the pressing block 21 from the female mould 1, then removes the pressed diamond grinding wheel from the accommodating groove 11, and finally cleans up the core mould 3 in the accommodating groove 11 so as to carry out next diamond pressing.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
