The specific embodiment
Referring to figs. 1 through Fig. 4, a kind of permanent ferrite magnetic tile wet pressing full chamfer mould that is shaped comprises the patrix 1, middle mould 3 and the counterdie 2 that cooperatively interact, and described patrix 1 comprises upper mold core 11, the molding plane 12 of upper mold core 11 is an arc-shaped concave, and the both sides of molding plane 12 are provided with fillet surface 13; Described counterdie 3 comprises lower mold core 21, and the molding plane 22 of lower mold core 21 is an arc convex, and the both sides of molding plane 22 are provided with fillet surface.Since the molding plane 12,22 of upper and lower core rod 21 all be provided with accordingly fillet surface 13,, just magnetic shoe has formed chamfering in respective edges in the process of moulding, behind sintering, need not to carry out again chamfer machining, on the one hand can simplified processing process, reduce the cost, cause the breakage of magnetic shoe in the time of can avoiding chamfer machining on the other hand.
Because be to adopt the extrusion modling in mould of magnetic slurry, just in forming process, the moisture in the slurry need be discharged outside the mould.Certainly there is fit clearance in each parts of mould, moisture can be discharged by the gap, but this water discharge method can cause the magnetic shoe germule to produce a lot of burrs, and the surface is comparatively coarse, just need bigger processing capacity, technology trouble so in the sanding and polishing operation behind sintering.In order to address the above problem, be provided with osculum 14 in the upper mold core 11, an end of this osculum 14 extends to molding plane 12, and the other end links to each other with pumping equipment, is fixed with filter course 5 on forming surface 12.In the process of pressure forming, because squeezing action, the moisture of discharging passes filter course 5 and enters in the osculum 14, and by pumping equipment it is extracted out outside mould, and the effect of filter course 5 be to make moisture by but stoping solid in the slurry also to enter into osculum 14 is drawn out of.
In addition, above-mentioned filter type also can realize that example as shown in Figure 5 by be filled with filter core 15 in osculum 14.
With reference to Fig. 6, in order to enhance productivity, a plurality of submodules can be set in mould, just described patrix 1 also includes cope match-plate pattern 16, cope match-plate pattern 16 is provided with the installing hole 17 of a plurality of upper mold core 11, and position 18 is takeed on along laterally being provided with overlap joint in the top of upper mold core 11, is provided with and overlaps shoulder position 18 steps that cooperate 19 outside the installing hole 17 of upper mold core 11 accordingly, a plurality of upper mold core 11 are embedded in the installing hole 17 respectively and fix, and also are quite convenient during installation.Corresponding counterdie 3 also comprises lower bolster 24, has a plurality of lower mold core 21 fixing with lower bolster 24; In mould 2 also be provided with a plurality of nibs 31 that match with upper mold core 11 and lower mold core 21, just disposablely can produce a plurality of magnetic shoes simultaneously and suppress germules.
For the design that a plurality of moulding submodules are set in the above-mentioned mould, each submodule all needs corresponding drainage arrangement to match, in order to simplify the design of drainage arrangement, described patrix 1 also comprises water sucting plate 4, be provided with drainpipe 41 in the water sucting plate 4, be provided with a plurality of suction sides in the drainpipe 41 and communicate with the osculum 14 of cope match-plate pattern 16 respectively, the water side of drainpipe 41 then links to each other with pumping equipment; Water sucting plate 4 is fixedlyed connected with the upper surface of cope match-plate pattern 16, upper mold core 11 is fixed in the installing hole 17 of cope match-plate pattern 16 simultaneously.
If the suction side of drainpipe 41 is less, so just need on described water sucting plate 4, be provided with groove 42 with upper mold core osculum 14 corresponding positions, this groove 42 is communicated with the osculum 14 of upper mold core 11 and the drainpipe 41 of water sucting plate respectively.Just the moisture in the mould enters into groove 42 by osculum 14, flow to drainpipe 41 then and is drawn out of in the mould at last.The effect of its further groove 42 is to cushion in groove 42 and enter in the drainpipe 41 of water sucting plate 4 after concentrating at this from the water that each osculum 14 is discharged.
