Abstract
The utility model discloses an upper mode of a permanent magnetic ferrite wet-press, which comprises an upper model composed by strong conducting magnetic material provided with an arc recessed cavity, and the bottom of the arc recessed cavity is at least provided with a row of water uptake holes which are at least provided with two water-uptake holes, among which a connected water-uptake groove is arranged along the bottom of the arc recessed cavity. With the radian of the recessed cavity smaller than 90 degrees, the water uptake holes are uniformly arranged; with the radian bigger than 90 degrees, the water-uptake holes are arranged densely on both sides and sparsely in the middle, and the water-uptake groove is shallow in the middle and deep at both sides. The utility model provides several water-uptake holes on the upper model which can increase the water-uptake area. Each row of water-uptake holes connected with the water uptake groove increases the patency of the water uptake holes and solves the problems of low suppressing speed, low forming and producing efficiency. The utility model is of simple construction and remarkable effect, which can increase the producing efficiency of the permanent magnetic ferrite and qualified rate of the product.
Description
Technical field
The utility model relates to a kind of mould of making magnetic material product, especially relates to a kind of patrix of permanent ferrite magnetic tile Wet-pressing molding mould.
Background technology
At present, the patrix of the permanent ferrite magnetic tile Wet-pressing molding mould that magnetic material ferrite production enterprise uses adopts suction slot type structure or uniform suction cellular type structure mostly.Yet these two kinds of structures have following defective: 1, when compression moulding, leaking water and easily stop up slowly in pick trough or suction hole, causes pressing speed slow, and moulding production efficiency is low; Defectives such as 2, these the two kinds uniform modes of leaking water cause blank corner portion density to hang down difficult moulding when the permanent ferrite magnetic tile goods of the big radian of compression moulding (greater than 90 degree) easily, and the many rate of finished productss of goods crackle are low.
Summary of the invention
The technical problems to be solved in the utility model be the patrix of existing mold when compression moulding, leaking water and easily stop up slowly in pick trough or suction hole, causes pressing speed slow, moulding production efficiency is low; And when the permanent ferrite magnetic tile goods of the big radian of compression moulding (greater than 90 degree), cause blank corner portion density to hang down difficult moulding easily, the many rate of finished productss of goods crackle are low, and a kind of patrix of the permanent ferrite magnetic tile Wet-pressing molding mould that can solve the problems of the technologies described above is provided.
The technical solution of the utility model is: a kind of patrix of permanent ferrite magnetic tile Wet-pressing molding mould, comprise the patrix that constitutes by strong permeability magnetic material, be equipped with the arc cavity on the patrix, arc cavity bottom is equipped with row's suction hole at least, at least be equipped with two suction holes in one row's suction hole, be equipped with one along arc cavity bottom between the suction hole and be communicated with the suction groove.
The arc of cavity is less than 90 degree, and the uniform arrangement in hole absorbs water; Radian is spent greater than 90, the suction rare arrangement in close centre, both sides, hole, and shallow both sides are dark in the middle of the suction groove.
The diameter in suction hole is between 1.5～3mm; The width of suction groove between 0.5～2.5mm, the degree of depth is between 0.5～1.5mm.
The utility model is provided with some suctions hole on patrix, can increase the suction area, and every row Kong Jun that absorbs water has pick trough to be connected, and has increased the unobstructed property in suction hole, and it is slow to have solved pressing speed, the problem that moulding production efficiency is low.
When the cavity radian of patrix was spent less than 90, uniform arrangement mode was adopted in the suction hole; When the cavity radian of patrix was spent greater than 90, the rare arrangement mode in close centre, both sides was adopted in the suction hole, and pick trough adopts the dark structure in middle shallow both sides.Also solved when the permanent ferrite magnetic tile goods of the big radian of compression moulding (greater than 90 degree), caused blank corner portion density to hang down difficult moulding easily, the low technical problem that waits of the many rate of finished productss of goods crackle.
Therefore, the utlity model has simple in structure, the apparent chopsticks of effect, can improve the production efficiency of permanent ferrite magnetic tile goods and the beneficial effects such as qualification rate of product.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Shown in Fig. 1 to 5, a kind of patrix of permanent ferrite magnetic tile Wet-pressing molding mould, comprise the patrix 1 that constitutes by strong permeability magnetic material, patrix 1 is provided with shaping cavity 4, cavity 4 is curved, arc cavity 4 bottoms have row's suction hole at least, have two suction holes 2 at least in row's suction hole, have one to be communicated with suction groove 3 along arc cavity 4 bottoms between the suction hole 2.Can increase the suction area like this, every row Kong Jun that absorbs water has suction groove 3 to be connected, and can increase the unobstructed property in the hole 2 that absorbs water, and the solution pressing speed is slow, the problem that moulding production efficiency is low.
As Fig. 4, shown in 5, when the cavity radian L of patrix spent less than 90, uniform arrangement mode was adopted in suction hole 2.
As Fig. 1, shown in 2, when the cavity radian L of patrix spent greater than 90, the rare arrangement mode in close centre, both sides was adopted in suction hole 2, and suction groove 3 adopts the dark structure in middle shallow both sides.Be used for solving when the permanent ferrite magnetic tile goods of the big radian L of compression moulding (greater than 90 degree), cause blank corner portion density to hang down difficult moulding easily, the low technical problem that waits of the many rate of finished productss of goods crackle.
Be to improve the quality of product, as preferably, the diameter in suction hole 2 is between 1.5～3mm; The width of suction groove 3 between 0.5～2.5mm, the degree of depth is between 0.5～1.5mm.
Specific embodiment of the utility model:
The patrix of permanent ferrite magnetic tile Wet-pressing molding mould, process by No. 45 steel, patrix cavity radian is 115 degree, and by shown in Figure 1, the rare arrangement mode in close centre, both sides is adopted in the suction hole, there are 9 rows, 12 row totally 72 suction holes in the every chamber of patrix, the suction bore dia is 1.5mm, and row's spacing is 4mm, and the suction hole is all arranged on the node of the every arrangement in both sides, and the centre is not that the suction hole is all arranged on each node, reaches the rare arrangement effect in suction close centre, both sides, hole.10mm in the middle of spacing is carried out the transition to by the 4mm on the limit, every row absorbs water and is connected in pick trough between the hole, and the pick trough width is 1.5mm, and the degree of depth is 1mm.
During use, patrix is installed on the mould bases, forms complete mold with other accessory simultaneously.During compacting on patrix and middle intermode pad suitable filter paper or filter cloth, then the permanent-magnet ferrite paste materials of ultrafine dust is injected low difficult moulding of mould corner portion density and the low problem of the many finished products of product crackle.In extrusion process, the Ferrite Material in the die cavity is magnetized, make the well-regulated arrangement of particle in the material, treat complete moulding after, demagnetizing disappears magnetic, in order to using.
