Description
Technical field
The utility model relates to magnetic-field orientation forming module technical fields, are axially molded more particularly to a kind of pole anisotropy
Mold.
Background technique
With the development of contemporary science and technology, the demand for moulding magnetic mold components increases sharply, and traditional processing technology is not only time-consuming to be consumed
Power, and be difficult to reach the requirement that client specifies when making shape or complicated accurate magnetic mold, production limitation is larger,
Currently, existing axial multipole oriental magnetic ring is to be embedded in assembled in iron-clad, phase by several pieces of magnet ring weeks on the market
There are corresponding gap between adjacent two blocks of magnet, this kind of production method is taken a long time, and subsequent to need to be sintered, process is complex, raw
Produce efficiency it is more low, and due to the fit-up gap between magnet be difficult to keep height it is uniform so that also will affect magnet ring use when
Effect.
In view of this kind of situation, people begin trying the mold that production magnet rotor is prepared with the means of injection molding, note
It is high to mould molding mould strength, without crackle and arrisdefect, is able to satisfy production shape or the magnet that structure is complicated, dimensional tolerance is high
It is required that.It can be integrally formed jointly with other components, reduce cost.And it is saved using the magnet rotor that injection mold is produced
The process that later period magnetizes and polishes, time saving and energy saving, energy conservation and environmental protection.
Utility model content
In view of the above problems, the utility model is intended to provide a kind of pole anisotropy axial direction injection mold, can prepare
Integrally formed magnet rotor, upper magnetic is simple, high production efficiency, saves the process that later period polishing is magnetized, is a kind of energy conservation and environmental protection
Production new technique.
To achieve the goals above, technical solution used by the utility model is as follows: a kind of pole anisotropy axially injection molding
Mold is equipped with fixed mold, in moving template and fixed mold including solid plate and moving template setting up and down in solid plate
Corresponding position be equipped with dynamic mould core, the top of dynamic mould core be equipped with product type chamber, in the fixed mold with the production
The corresponding position of product type chamber is equipped with the high-performance permanent magnet block that even number annular surrounds, and the bottom of the high-performance permanent magnet block is higher than institute
State the bottom of fixed mold.
Further, it is equipped with center fixed link in the dynamic mould core, bar is equipped in the middle part of the high-performance permanent magnet block
Slot, the center fixed link can slide up and down in the bar slot.
Further, the dynamic mould core, fixed mold and product type chamber are made of non-magnetic alloy material.
Further, the high-performance permanent magnet block is made of neodymium iron boron.
Further, the center fixed link is made of non-magnetic alloy.
The beneficial effects of the utility model are:
The one-time injection molding of the achievable magnet rotor of pole anisotropy axial direction injection mold, mold knot disclosed in the utility model
Structure is simple, and operating effect is good, significant to shorten the production time, uses manpower and material resources sparingly；Compared with prior art, the magnet rotor of preparation
No longer need to carry out the later period magnetize, the process of later period grinder buffing is more omitted compared with sintering prepares the technique of magnet rotor,
Production link energy conservation and environmental protection, the discharge of no heavy contaminant.

Specific embodiment
In order to make those skilled in the art be better understood on the technical solution of the utility model, below with reference to attached
Fig. 1 and embodiment are further described the technical solution of the utility model.
It should be noted that embodiment provided by the utility model merely to the technical characteristics of the utility model into
The effective explanation of row, the left side, right side, upper end, lower end etc. position word merely to carrying out to the utility model embodiment
Preferably description, is not to be regarded as being the limitation to technical solutions of the utility model.
A kind of pole anisotropy axial direction injection mold is set in solid plate 1 including solid plate 1 and moving template 2 setting up and down
There is fixed mold 3, position corresponding with fixed mold 3 is equipped with dynamic mould core 4 in moving template 2, sets at the top of dynamic mould core 4
There is product type chamber 5, position corresponding with the product type chamber 5 is equipped with the height that even number annular surrounds in the fixed mold 3
Performance permanent magnets 6, the number of high-performance permanent magnet block 6 can be four and be also possible to six, but with the increasing of permanent magnets number
Greatly, magnetic pole is also more, and corresponding production difficulty also can be amid a sharp increase；It is described fixed that the bottom of the high-performance permanent magnet block 6 is higher than
The bottom of model core 3, fixed mold 3 can also serve as the effect of no magnetic sleeve at this time, with to avoid product when injection molding and the height
Performance permanent magnets 6 directly contact.
It is equipped with center fixed link 7 in the dynamic mould core 4, bar slot 8, institute are equipped in the middle part of the high-performance permanent magnet block 6
Stating center fixed link 7 can slide up and down in the bar slot 8.
The dynamic mould core 4, fixed mold 3 and product type chamber 5 are made of non-magnetic alloy material, due to these three
