Description
Technical field
The utility model is related to mould water sucting plate on a kind of forming die for permanent magnet ferrite magnetic shoe.
Background technology
At present, magnetic shoe mould vertical row water hole be with concave die cavity opposite position, it is curved below water sucting plate, arc
Another side（Above）There is drain chamber, drain chamber is vertical with osculum, drain chamber is concordant with suction hole upper end.Such upper die structure
In compacting, portion of water can enter negative pressure bucket by drain chamber；Portion of water is by the filter cloth between upper mould and middle mould
Beyond discharge osculum, water sucting plate backwater phenomenon when causing compacted products easily produces green compact chamfering to split；When green compact are big from gravity
In negative pressure of vacuum suction, green compact will be in punch-pin cambered surface, and arcwall face osculum is turned on by filter cloth with air, horizontal drainage
In the case where that can not form negative pressure, the stealth that a part of water is dropped on green compact when causing product to sinter when die sinking takes base is split in chamber
Line.After compacting terminates die sinking, the suction when green compact from gravity less than negative pressure of vacuum, green compact will be inhaled on water sucting plate；Work as life
Base from gravity be equal to true hole negative-pressure sucking when, just there is product to fall in punch-pin cambered surface, cause green compact tumble injury crackle.
Although patent 2012204524125 has done the improvement of correlation for the problem, when green compact are larger, moisture circulation
Flowed over because vertical suction hole is too small slowly, be easily caused water flow not in time；The tank water outlet of periphery conducting simultaneously is still from upper mould
By moisture may be made to splash on green compact, invisible crack when causing to sinter.
Utility model content
The technical problems to be solved in the utility model is the drawbacks described above for overcoming prior art to exist, there is provided one kind can have
Effect improves mould water sucting plate on the forming die for permanent magnet ferrite magnetic shoe of green compact quality.
The utility model solves the technical scheme that its technical problem used：
Mould water sucting plate on a kind of forming die for permanent magnet ferrite magnetic shoe, includes upper surface and bottom surface, and there are both sides upper surface
Inside slope, bottom surface is cambered surface, vertical suction hole is evenly equipped between upper surface and bottom surface, it is characterised in that slope
U-shaped tank is provided with minimum point, U-shaped tank is communicated with discharge outlet, upper surface both sides are provided with horizontal tank, horizontal tank be close to
Vertical suction hole at magnetic shoe chamfering is communicated.
Further, the vertical suction hole is divided into two sections, and the epimere of vertical suction hole is with diameter greater than hypomere diameter.It is perpendicular
The hypomere diameter of straight suction hole is small, advantageously ensures that on the premise of water flow, realizes that suction hole vestige is not during the green compact demoulding
Substantially；The epimere diameter of vertical suction hole is big, is capable of achieving the quick flowing of moisture.The epimere diameter of vertical suction hole can be hypomere
2 times of diameter.
Further, the outer side edges of the upper surface are provided with the unfilled corner communicated with horizontal tank, are beneficial to so that processing more square
Just.
Further, the angle of inclination of the slope is 10 °.
Its principle is：When product magnetizing Wet-pressing molding, the slurry portion of water in injection die cavity is sucked by filter cloth
The vertical suction hole of water sucting plate, both sides moisture flows into U-type groove by inclining to be assembled towards centre, and U-type groove is communicated with discharge outlet,
Moisture is siphoned away by negative pressure again；Another fraction moisture by directly flowing out outward after vertical suction hole through horizontal tank.
In the utility model, U-shaped tank is set by slope lowest part, it is ensured that from the water that vertical suction hole comes
Shunt toward U-shaped tank, U-shaped tank is communicated with discharge outlet, it is ensured that moisture is discharged in time in pressing process, solves permanent-magnet ferrite
Backwater phenomenon when forming magnetic tile is suppressed.Communicated with the vertical suction hole at magnetic shoe chamfering by horizontal tank, be capable of achieving magnetic
The timely discharge of moisture at watt chamfering.Using the utility model, green compact tumble injury phenomenon, green compact chamfering when can effectively prevent from molding
Split, remaining water droplet falls the generation of the phenomenons such as green compact, the quality of green compact can be effectively improved, improve yield rate, reduces cost.
Brief description of the drawings
Fig. 1 is the schematic diagram of mould water sucting plate on forming die for permanent magnet ferrite magnetic shoe.
Specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Mould water sucting plate on a kind of forming die for permanent magnet ferrite magnetic shoe, with upper surface 1 and bottom surface 2, there are both sides upper surface 1
Inside slope 3, is provided with U-shaped tank 6 at the minimum point of slope 3, U-shaped tank 6 is communicated with discharge outlet 7, and bottom surface 2 is cambered surface 4,
Be evenly equipped with vertical suction hole 5 between upper surface 1 and bottom surface 2, the both sides of upper surface 1 are provided with horizontal tank 8, horizontal tank 8 be close to
Vertical suction hole 5 at magnetic shoe chamfering is communicated.
5 points of the vertical suction hole is two sections, and the epimere of vertical suction hole 5 is with diameter greater than hypomere diameter.Inhale vertically
The hypomere diameter in water hole 5 is small, advantageously ensures that on the premise of water flow, realizes that suction hole vestige is failed to understand during the green compact demoulding
It is aobvious；The epimere diameter of vertical suction hole 5 is big, is capable of achieving the quick flowing of moisture.
The outer side edges of the upper surface are provided with the unfilled corner 9 communicated with horizontal tank, are beneficial to so that processing more convenient.
The angle of inclination of the slope 3 is 10 °.
In the utility model, U-shaped tank 6 is set by the lowest part of slope 3, it is ensured that come from vertical suction hole 5
Moisture flow to U-shaped tank 6, U-shaped tank 6 is communicated with discharge outlet 7, it is ensured that moisture is discharged in time in pressing process, is solved forever
Backwater phenomenon when magnetic ferrites forming magnetic tile is suppressed.By horizontal tank 8 and the phase of vertical suction hole 5 at magnetic shoe chamfering
It is logical, it is capable of achieving the timely discharge of moisture at magnetic shoe chamfering.Using the utility model, green compact tumble injury shows when can effectively prevent die sinking
Split as, green compact chamfering, remaining water droplet falls the generation of the phenomenons such as green compact, can effectively improve the quality of green compact, improves yield rate, reduce
Cost.
