Abstract
The utility model relates to a small diameter multi pole different polarity permanent magnet mold cavity orientation mould, which consists of a non magnetic steel body (1) and a plurality of orientation magnets (2) arranged on the non magnetic steel body. A gap (3) is arranged between two neighboring orientation magnets (2). The utility model is characterized in that the mention a plurality of orientation magnets (2) directly contacts the work piece. As the orientation magnets directly contact the required products, the utility model effectively improves the orientation degree of the plastic magnetic products and the magnetism of the products.
Description
Technical field
The utility model relates to a kind of magnetic product development mould of moulding, and is the multipole different in nature permanent magnet die cavity orientation mould of a kind of minor diameter specifically.
Background technology
At present; mould the magnetic product on stream; having sheath on the mold cavity does not promptly have magnet ring, makes orientation magnetic and need mould between the product of magnetic one deck sheath is arranged, extremely wide bigger as fruit product; the degree of orientation and table magnetic property to product do not influence like this; but run into miniature multipole product through regular meeting, as stepping motor rotor etc., because product extremely wide very little (less than 1.5mm); the degree of orientation and table magnetic property are difficult to reach designing requirement, can't satisfy client's instructions for use.
As mentioned above, there is following deficiency in prior art: with the orientation magnetic and need mould one deck sheath is arranged between the product of magnetic multipole different in nature permanent magnet die cavity orientation mould when injection moulding is produced, the degree of orientation of moulding the magnetic product is low, the table magnetic property is poor.
Summary of the invention
The utility model solved that prior art exists with the orientation magnetic and need mould between the product of magnetic and have the multipole different in nature permanent magnet die cavity of one deck sheath to be orientated mould when injection moulding is produced, the degree of orientation of moulding the magnetic product is low, the problem of table magnetic property difference provides a kind of and has been orientated magnetic and waits to put the multipole different in nature permanent magnet die cavity orientation mould of minor diameter that product directly contacts.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: the multipole different in nature permanent magnet die cavity orientation mould of a kind of minor diameter, comprise nonmagnetic steel body and the some orientation magnetics that are provided with thereon, wherein, described some orientation magnetic hoops are evenly distributed on the nonmagnetic steel body, it is characterized in that described some orientation magnetics directly contact with the part of waiting to knock off.Having cancelled originally, the sheath between product and orientation magnetic does not promptly have magnet ring, make the orientation magnetic directly contact with product, equaled to strengthen the magnetic field intensity of alignment magnetic field, alignment magnetic field is enough big to the product of need injection moulding magnetic like this, effectively improve the degree of orientation of moulding the magnetic product, also improved the table magnetic property of product.
As preferably, described orientation magnetic is a wedge shape, between the two adjacent orientation magnetics leave the gap.Gap smallest end around here is less than 1.5mm, is used for the multipole different in nature product of injection moulding minor diameter.
The utility model is skillfully constructed, and directly contacts with product by making the orientation magnetic, has effectively improved the degree of orientation of moulding the magnetic product, has also improved the table magnetic property of product.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described further.
Embodiment 1.See Fig. 1, the multipole different in nature permanent magnet die cavity orientation mould of this routine a kind of minor diameter, comprise nonmagnetic steel body 1 and the some orientation magnetics 2 that are provided with thereon, orientation magnetic 2 is a wedge shape, its reason nonmagnetic steel body 1 edge, outer end also has a segment distance, wherein, described some orientation magnetics 2 radially are evenly distributed on the nonmagnetic steel body 1, and two leave gap 3 between the adjacent orientation magnetic 2, the smallest end width in gap 3 is less than 1.5mm, most critical be that described some orientation magnetics 1 directly contact with workpiece in waiting to be placed on mold cavity.So cancelled the no magnet ring between product and orientation magnetic originally, alignment magnetic field is enough big to the product of need injection moulding magnetic like this, has effectively improved the degree of orientation of moulding the magnetic product, has also improved the table magnetic property of product.
It is apparent to one skilled in the art that the utility model can be changed into multiple mode, and such change is not thought and broken away from scope of the present utility model.What all were such will be included within the scope of this claim the conspicuous modification of described those skilled in the art.
Claims (3)
1, the multipole different in nature permanent magnet die cavity orientation mould of a kind of minor diameter, comprise nonmagnetic steel body (1) and the some orientation magnetics (2) that are provided with thereon, leave gap (3) between the two adjacent orientation magnetics (2), it is characterized in that described some orientation magnetics (2) directly contact with the part of waiting to knock off.
2, the multipole different in nature permanent magnet die cavity orientation mould of minor diameter according to claim 1 is characterized in that described some orientation magnetics (2) hoop is evenly distributed on the nonmagnetic steel body (1).
3, the multipole different in nature permanent magnet die cavity orientation mould of minor diameter according to claim 1 and 2 is characterized in that described orientation magnetic (2) is wedge shape.
