Description
Technical field
The present invention relates to a kind of unitary mould, particularly relate to the unitary mould that a kind of stamping of powder is shaped.
Background technology
Bonding rare earth built-up magnet, particularly bonding rare earth magnet comprise Agglutinate neodymium-iron-boron magnet, bonding neodymium iron nitrogen, bonding SmCo and every bonded permanent magnet that contains rare earth element, and they are widely used in each big industry.For example: the IT industry: a.3.5 inch is to 0.8 inch large-scale and miniature hard disk drive bonding rare earth magnet, bonding rare earth magnet among b.CD-ROM, ODD, DV, VCD, the DVD, c. digital product, bonding rare earth magnet among digital gamma camera, digital camera, MP3, PDA, the GPS, d. the bonding rare earth magnet in buzzer, the loudspeaker, the bonding rare earth magnet in e. duplicator, printer, scanner, the color laser imaging machine etc.; The communications industry: the bonding rare earth magnet in a. mobile phone, the bonding rare earth magnet in b. and related transmission, control and the buzzing system of communication; Bonding rare earth magnet in the various electric motor of automobile of automobile industry: a., the bonding rare earth magnet in the various automobile sensors of b., transmission that c. is related with automobile and the bonding rare earth magnet in the control system; Bonding rare earth magnet in electronic product, electrical equipment, motor, the instrument and meter.
Rare earth-like bonded permanent magnet is to use the mixture of rare earth magnet powders and binding resin (organic bond).Be used to make this rare earth-like bonded permanent magnet composition, and use rare earth-like bonded permanent magnet generally to have three kinds: injection molding method, extrusion molding method and compression forming method with the manufacture method of the rare earth-like bonded permanent magnet of composition.
Injection molding method is with aforementioned mixture heating and melting, under keeping abundant mobile state this fused mass is injected in metal pattern, by the method for predetermined magnet shape shaping.Require the flowability of fused mass to have high level when adopting this method to be shaped, therefore must add a large amount of bonding thermoplastic resins, thereby it is many to have in the resulting magnet thermoplastic resin amount, the shortcoming that magnetic characteristic is low.
The extrusion molding method is the said mixture heating and melting that will infeed in the extrusion moulding machine, and this mixture is extruded from the metal pattern of extrusion moulding machine, and cooled and solidified simultaneously cuts into desired length with resulting long size formed body again and makes the method for magnet.This method and injection molding method all need to add the bigger bonding thermoplastic resin of quantity, to the mixture heating and melting, but also need to shear, shear gap need consume certain material, thereby step complexity, and it is more to have in the resulting magnet thermoplastic resin amount, the shortcoming that magnetic characteristic is lower.
Compression forming method is that said mixture is filled in the forcing press metal pattern, and its pressurization compression is obtained formed body, makes the method for making magnet as the thermosetting resin heat hardening of binding resin then.Compare with other method, even this method also can be shaped in the binding resin amount after a little while, therefore amount of resin is few in the resulting magnet, and this raising to magnetic characteristic is favourable.
In the compression forming method, press forming is a procedure necessary in the composite RE body, and in the middle of the prior art, what the mould of press adopted usually is split type mould.
The structure of split mould be last punch projection vertically downward, bottom and last punch fixing body are fixed; The projection of lower punch vertically upward, bottom and lower punch fixing body are fixed;
Die is inlayed and is fixedly mounted in the die supporter; Plug and guide pillar vertical fixing are installed on the base plate; Guide pillar is with the punch fixing body from the top down, die supporter and lower punch fixing body; Die case is on lower punch projection top, and lower punch is enclosed within plug top.
Use this split mould compacting bonding rare earth built-up magnet to have following shortcoming: a. will be installed to the split mould at every turn and just can adjust precision after press (punch press) is gone up, because die is installed on the die supporter, and plug is fixed on the die bottom plate, so when mould only is installed on the press pedestal, could adjust the relative position of die and plug, so not only waste time and energy, inefficiency, and also precision also is not easy to adjust high;
B. because plug is fixed on the base plate, and its top will pack in the lower punch, so that plug will be designed is very long, long plug has not only increased the difficulty of degree of regulation, and impaired easily in compacting;
C. work as lower punch and move down, when taking out workpiece, plug is motionless, and workpiece can so this mould is relatively more difficult when taking out workpiece, because composite RE body is frangible, can cause complex workpiece percentage of damage height again above plug;
D. when lower punch returns the next workpiece of origin-location continuation compacting, might change with the relative position of plug, thereby cause product size precision and the unapproachable consequence of form and position tolerance precision.
Summary of the invention
The purpose of this invention is to provide the unitary mould that a kind of stamping of powder is shaped, it overcomes existing split mould when the preparation part, accessory size and the not high defective of form and position tolerance precision by further optimizing mould structure.
Compare unitary mould of the present invention is many two parts, one die cavity and lower punch support with existing split mould.The shape of one die cavity is as a container, to be that the upper and lower is not of uniform size cause external structure, it is bigger to be generally top, the bottom is less, can conveniently be embedded in the die supporter like this, bolt hole or screw hole are arranged on the plane at size variation place, and one die cavity and die supporter are fixed by bolt or screw like this, and the bottom of one die cavity is provided with the hole that can allow lower punch bracket leg dagger pass through.
The internal structure of one die cavity is, the shape size of top is the same with die shape size, die can be embedded in wherein, bolt hole or screw hole are arranged on the plane at size variation place, one die cavity and die are fixed by bolt or screw like this, and on the die on plane and the one die cavity plane be in same plane; The space of below is compared smaller with the top, can hold lower punch, plug, the gripper shoe of lower punch support and part support column.
The lower punch support is made up of three parts, gripper shoe, support column and fixed head.Gripper shoe supports lower punch in the top, and there is a hole at the gripper shoe middle part, can allow plug pass.Support column is at the middle part, and it passes the bottom outlet of one die cavity, upwards connects gripper shoe and is connected and fixed plate downwards.Fixed head is fixed with fixture and lower punch fixing body.
The plug bottom is fixed with fixture with one die cavity bottom, and plug passes the hole of lower punch bracket leg fagging, is inserted in the lower punch.Lower punch is placed on the gripper shoe, and projection is inserted in the die hole.
During work, the motion of die supporter can drive one die cavity, die and plug simultaneously and do identical motion up or down.When die moves upward with respect to lower punch, powder enters in the die cavity of die, plug and lower punch formation, lower end part in the die cavity has the last plane of lower punch to enter the bottom of die cavity as powder, enter the quantity of powder of the die cavity of die, by the last plane of lower punch to the distance the last plane of die, i.e. the space decision that forms by the degree of depth of the die cavity of die.
Die, plug move downward with respect to lower punch, and lower punch is motionless relatively, and workpiece is ejected, and workpiece rests on the last plane of die.
The invention has the beneficial effects as follows that the adjustment of this unitary mould precision can not carried out, and just can obtain the mould of precision height, integration on press (punch press); The high accuracy of mould can be maintained; The easy accessibility of high-precision mold on press (punch press) saved dismounting man-hour.
