Detailed description of the invention
Below in conjunction with drawings and Examples, embodiments of the present invention are described in further detail.Following examples for illustration of the present invention, but can not be used for limiting the scope of the invention.
Embodiment 1
As shown in Figure 1, the lower mould insert 1 of the present embodiment and deburring insert 2, counterdie insert 1 and deburring insert 2 are installed in the main body of mould, counterdie insert 1 is provided with cutting edge 3, cutting edge 3 is the rectangular recess of cross section, deburring insert 2 is corresponding with cutting edge 3 to be arranged, and deburring insert 2 can by the cutting edge 3 of material to be processed press-in counterdie insert 1, is treated rapidoprint carried out deburring by coordinating of deburring insert 2 and cutting edge 3.
The center of the cutting edge 3 of counterdie insert 1 is provided with a strip projection 4 along the bearing of trend of cutting edge 3, and projection 4 is on the Xiu Chong direction of mould, it is arranged on the position of the easy stuck waste material of cutting edge 3, the cross section of protruding 4 is trapezoidal, and the upper surface of protruding 4 and the attached type of waste material 6 are (namely with the shape of the lower surface of waste material 6 and highly corresponding, the upper surface of protruding 4 is contacted with the lower surface of waste material 6 before deburring) or lower than 6 one, waste material expect thick within, to play the effect better supporting waste material 6, the lower end of deburring insert 2 is provided with the recess 5 corresponding with protruding 4 positions, the cross section of recess 5 is rectangle.In order to ensure the intensity of protruding 4, the upper end width of protruding 4 should be greater than 10mm, the draft angle of protruding 4 should be less than 30 °, the lower end width of recess 5 should be greater than the upper end width of protruding 4, recess 5 can be 5mm ~ 15mm with the stand out of projection 4, the preferred 10mm of the present embodiment, the degree of depth of recess 5 can be 10mm ~ 20mm, and the present embodiment is preferably 15mm.Those skilled in the art should select projection 4 and the recess 5 of suitable dimension according to the grinding tool size of reality, scantling to be processed and processing request etc.Protruding 4 can process together with counterdie insert 1, also can set up in the later stage in the cutting edge 3 of counterdie insert 1.
As shown in Figure 2, when deburring insert 2 to coordinate with counterdie insert 1 carry out deburring time, material to be processed is cut off by cutting edge 3, cut waste material 6 is clipped between counterdie insert 1 and deburring insert 2, now, protruding 4 also inject in recess 5, by the mating reaction of projection 4 with recess 5, can make to be extruded distortion by the waste material 6 that cutting edge 3 cuts during deburring, folding or the fracture of waste material 6 makes its width reduce, thus make waste material 6 be easy to depart from cutting edge 3 and be beneficial to skid off from cutting edge 3 downwards, effectively avoid the phenomenon that waste material 6 is stuck in the cutting edge 3 of counterdie insert 1.
Embodiment 2
The mould of the present embodiment and the difference of embodiment 1 are, protruding are many, and are arranged in parallel in the cutting edge of counterdie insert, and the arrangement of this projection can for the larger material to be processed of edge width, the more convenient extruding to waste material.Equally, shape of cross section that is protruding and recess also can change into semicircle etc.
Projection in above-mentioned two embodiments also can be the projection of the multiple bulks arranged along the bearing of trend of cutting edge, if hemispherical, cross section are trapezoidal or semicircular little short cylinder etc., and recess also can be strip or osculum shape, can reach like this and save cost and processing and object easy for installation.
Those skilled in the art should select the shape of multi-form projection arrangements mode and projection, recess according to actual conditions, as long as it meets arrange projection and recess on the cutting edge and deburring insert of counterdie insert, make waste material be extruded distortion, thus be easy to depart from and skid off cutting edge.
Embodiments of the invention provide in order to example with for the purpose of describing, and are not exhaustively or limit the invention to disclosed form.Many modifications and variations are apparent for the ordinary skill in the art.Selecting and describing embodiment is in order to principle of the present invention and practical application are better described, and enables those of ordinary skill in the art understand the present invention thus design the various embodiments with various amendment being suitable for special-purpose.
