Further, the heights of the front baffle, the rear baffle and the groove plate and the width of the backing plate are the same as the thickness of the aluminum frame.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model provides a diamond resin emery wheel hot pressing mould will have the current annular structure hot pressing mould even cut apart into a plurality of independent hot pressing mould, has formed a plurality of independent mould chambeies through preceding baffle, backplate, pressure head and frid, will have the process of powder, scraping powder and pre-compaction change the present dress in the ring channel into and implement more than the step in a relatively less within range, more be favorable to producing the resin emery wheel of quality homogeneous.

2. The ring dress mould of prior art is because the reason of its mould cavity structure, is difficult to be in the even distribution of powder in the mould intracavity with the powder when powder and pre-compaction are adorned, during the pre-compaction, the powder surface is also difficult for flattening, consequently is unfavorable for in annular structure hot pressing mould to add the end powder, and the utility model provides a can be very easy among the hot pressing mould realize the pre-compaction of powder flat and add the end powder to manufacturing cost has been reduced.

3. The diamond resin grinding wheel hot pressing die takes the size of the drainage groove of the grinding wheel into consideration in the design process, so that after the grinding wheel is pressed, a single independent grinding wheel tool bit is only required to be indicated according to the index plate and bonded at a fixed position, the diamond resin grinding wheel with the water groove can be obtained, and defective products caused by later-stage cutting of the water groove are avoided.

Detailed Description

The present invention will be described in further detail with reference to examples.

Example 1

Fig. 1 to 5 show schematic structural views of the diamond resin grinding wheel hot pressing mold of the present embodiment. As shown in fig. 1, the mold comprises an aluminum frame 2, threaded holes are respectively formed in two adjacent side faces of the aluminum frame 2 and provided with bolts 1, a front baffle 4, a groove plate 7, a rear baffle 5 and backing plates 3 are arranged in the aluminum frame 2, the front baffle 4 and the rear baffle 5 are placed in parallel with two inner walls opposite to the aluminum frame 2, the groove plate 7 is placed in parallel between the front baffle 4 and the rear baffle 5, and at least two backing plates 3 are arranged on the inner walls of the aluminum frame 2. The die further comprises a pressure head 6, wherein the pressure head 6 comprises an upper pressure head and a lower pressure head, and the upper part and the lower part of the front baffle plate 4, the groove plate 7 and the rear baffle plate 5 are respectively provided with the pressure head 6. The space between the front baffle and the groove plate, the space between the groove plate and the groove plate, and the space between the rear baffle and the groove plate in the mold are mold cavities.
