Abstract
The utility model relates to an automatic pouring mould for permanent magnet ferrite wet pressing magnetic tile. The mould is characterized in that more than one sealing groove are arranged at the circumference of the lower part of the lower mould, a sealing ring is arranged in the sealing groove; vertical pouring not-through holes corresponding to the material-storage room are respectively arranged at the two sides of the lower mould, at the lower end face of the middle mould. A horizontal waist-shaped hole communicated with the mould cavity is arranged at the upper part of the middle mould corresponding to the mould cavity; the horizontal waist-shaped hole is communicated with the upper part of the vertical pouring not-through hole. By the improvement on the prior mould, the leakage of material slurry is solved, and the same distance and same quality can be ensured; the density of the roughcast of the magnetic tile is even; the crack of the roughcast is reduced; the problem that the strength of magnetic tile is not stable is overcome, thereby, the mould difficulty is reduced and the service life of mould is prolonged.
Description
Technical field
The utility model relates to permanent-magnet ferrite wet pressing magnetic shoe automatic-feeding mould.
Background technology
The ferrite magnetic shoe is widely used in all kinds of engine casings, and its shape is different because of the difference of user's request, and common feature is a small semicircle annular or near semi-round ring shape.The magnetic shoe mould is exactly to design according to this.Mainly be made up of patrix, middle mould and counterdie, open cavity on middle mould, during compacting, form die cavity jointly by middle mould cavity and upper die and lower die, general one pair of mould has two with upper cavity.At present, known automatic-feeding magnetic shoe mould has slot type material feeding and the board-like material feeding dual mode of runner, by feeding machine slip is injected die cavity from mould material feeding groove or runner plate hole during moulding, under the effect of magnetic field, uses hydraulic press compression moulding.But the slot type material feeding because there are the gap in middle mould and counterdie, and does not have sealing, can't avoid slip to leak, influence green body quality, and because of slip in the gap, increase mould resistance die cavity easy to wear and counterdie, shortened service life, runner is board-like because of slip is diverted in each die cavity by the runner plate duct, and the material feeding path is tortuous tediously long and unequal, and the duct is easily stopped up, cause each die cavity shot not wait, thereby the product density that a mold pressing is gone out does not wait and influence green body quality.
Summary of the invention
The purpose of this utility model is: by the improvement to existing mold, slip did not leak, reduces die wear, can guarantee the permanent-magnet ferrite wet pressing magnetic shoe automatic-feeding mould of material feeding equivalent when a kind of moulding was provided.
The improvement design that realizes above-mentioned purpose is as follows:
Permanent-magnet ferrite wet pressing magnetic shoe automatic-feeding mould comprises patrix, middle mould and counterdie, and the bottom of middle mould and counterdie is being communicated with the storage compartment, and the bottom of storage compartment is provided with the material feeding inlet, and the middle cavities of patrix, middle mould and counterdie correspondence is a die cavity,
A, the periphery in the counterdie bottom are provided with the seal groove of one or more, are provided with sealing ring in the seal groove;
B, in middle mould lower surface, corresponding with the storage compartment, be positioned at the counterdie both sides and be respectively equipped with upwards vertical material feeding the region between the heart and the diaphragm hole; In mould top, be provided with the horizontal mounting hole that is communicated with die cavity with the die cavity corresponding position, horizontal mounting hole is being communicated with vertically top, mould material feeding the region between the heart and the diaphragm hole.
Described material feeding the region between the heart and the diaphragm bore dia is a Φ 7-12 millimeter, and the axial line in material feeding the region between the heart and the diaphragm hole equates apart from the distance of the corresponding inwall of adjacent die cavity.
Described horizontal mounting hole hole is wide to be the 1.5-3 millimeter, and horizontal mounting hole is communicated with die cavity to the hole length between the material feeding the region between the heart and the diaphragm hole and is the 8-12 millimeter,
The aperture lower limb of horizontal mounting hole is corresponding with the punch arc summit of counterdie.
Described counterdie bottom radially be provided with two seal grooves, seal groove width 8-10 millimeter, groove depth 2.5-3 millimeter.
Useful technique effect of the present utility model is, by improvement to present mould, both solved the leakage problem of slip, can guarantee that again material feeding is equidistant, equivalent, the magnetic shoe blank density unanimity that one mold pressing goes out reduces the base substrate crackle, has overcome magnetic shoe mechanical strength problem of unstable behind the sintering, thereby reduced the moulding difficulty, prolonged the service life of mould.

Fig. 4 is an E portion enlarged drawing among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the mould that goes out 4 magnetic shoes with a mold pressing is that the utility model is further described for example.
Embodiment:
Permanent-magnet ferrite wet pressing magnetic shoe automatic-feeding mould comprises patrix 8, middle mould 3 and lower punch 2, the bottom of middle mould 3 and lower punch 2 is being communicated with storage compartment 4, the bottom of storage compartment 4 is provided with material feeding inlet 10, and the middle cavities of patrix 8, middle mould 3 and lower punch 2 correspondences is a die cavity 1, sees Fig. 1.
Periphery in lower punch 2 bottoms has two seal grooves 6, in the seal groove 6 sealing ring is housed, and sealing ring is the ox-hide circle, sees Fig. 1, seal groove width 8-10 millimeter, groove depth 2.5-3 millimeter.Can stop under crunch slip from die cavity 1 and lower punch 2 gaps, to leak during moulding.
In middle mould 3 lower surfaces, 4 corresponding with the storage compartment, be positioned at lower punch 2 both sides vertical material feeding the region between the heart and the diaphragm hole 9 upwards arranged respectively, see that Fig. 2 has six material feeding the region between the heart and the diaphragm holes, the diameter in material feeding the region between the heart and the diaphragm hole 9 is 10 millimeters.In mould 3 tops, with die cavity 1 corresponding position the horizontal mounting hole 5 that is communicated with die cavity 1 is arranged, horizontal mounting hole 5 is being communicated with vertically 9 tops, material feeding the region between the heart and the diaphragm hole, sees Fig. 2, Fig. 3.
Material feeding the region between the heart and the diaphragm hole 9 diameters are Φ 7-12 millimeter, and the axial line in material feeding the region between the heart and the diaphragm hole 9 equates apart from the distance of the corresponding inwall of adjacent die cavity.
The aperture lower limb of horizontal mounting hole 5 flushes corresponding with the arc summit 7 of lower punch 2, guarantee the material feeding free pathway, and when compression moulding, middle mould 3 moves down, lower punch 2 transfixions, because horizontal mounting hole 5 width on the die cavity 1 have only 3 millimeters, and are very fast by lower punch 2 shutoff, stop to make slip in die cavity, refund horizontal mounting hole 5 because of pressure in the die cavity increases gradually.
Because pressure is certain during the inherent moulding in storage compartment, so the flow velocity that slip 11 enters each material feeding the region between the heart and the diaphragm hole 9 is equal, at one time in, slip 11 equates at the flow in each material feeding the region between the heart and the diaphragm hole 9; In like manner the slip flow velocity also equates in horizontal mounting hole 5; Thereby in reaching at one time, the shot of injecting each die cavity equates.
