Space in mould cylinder is divided at least one carbon brush die cavity, and the composition carbon brush type of projection by projection, the projection inserted in mould cylinder
Outwardly convex R arcs are set in the side wall of chamber, and R arcs are consistent with required carbon brush side R arcs, the number of upper punch and the number of die cavity
Mesh is consistent.In compacting, in projection insertion mould cylinder, mould cylinder is divided into carbon brush die cavity, raw material is put into carbon brush die cavity, upper undershoot
The raw material that head is pointed in carbon brush die cavity is suppressed.
Although this carbon brush grinding tool can be suppressed raw material, due to being not provided with cooling device outside mould, press
Caused heat can not scatter and disappear during system, can reduce the quality of the carbon brush of compacting and shorten the mold use life-span.Secondly,
After the completion of compacting, the carbon brush of shaping still is difficult to take out in carbon brush die cavity.
The content of the invention
It is an object of the invention to provide it is a kind of carbon brush and drift cool down and can pushing out type intracavitary it is compressing
The mould of carbon brush, to extend the service life of mould and drift, quickly remove carbon brush in mould.
To reach above-mentioned purpose, the technical scheme is that：Be easy to take out carbon brush mold, including frame, mould and
Drift, mould are fixed in frame, and drift is located above mould；The piston that can be slided along mould side wall, mould are provided with mould
Cooling chamber is provided with side wall, cooling chamber is connected with the die cavity of mould and connectivity part is located at piston underside；Positioned at the institute of piston underside
State mold cavity and be connected with overflow valve and water pump in turn, overflow valve is also associated with drainpipe, and overflow valve and water pump are each attached to machine
On frame；Also include electromagnetism position-limit mechanism, electromagnetism position-limit mechanism includes mutually exclusive electromagnet and spacing magnet, electromagnet and limit
One in the magnet of position is fixed on piston lower surface, and another is fixed in frame, and above mould, drift runs through and is located at
Electromagnet or spacing magnet above mould, and can be with respect to its slip.
When suppressing carbon brush, first set the maximum pressure value of overflow valve, then open water pump and electromagnet, and to cooling chamber and
Water is added in die cavity in communication, now produces repulsive force between electromagnet and spacing magnet.Water pump is to positioned at piston underside
Die cavity in water-filling, the distance between electromagnet and spacing magnet are larger when initial, and repulsive force is smaller, now piston itself and
Be pressed in the presence of the gravity and repulsive force of electromagnet or spacing magnet it is waterborne in die cavity, due to now repulsive force compared with
Small, piston is smaller to the pressure of water, but the pressure in die cavity, still less than the setting value of overflow valve, water can continue to flow into from water pump
Die cavity, piston upward sliding.In the process, electromagnet and spacing magnet move closer to, and repulsive force gradually increases, and piston is to type
The pressure of intracavitary water gradually increases, and is compressed into the water in die cavity, and the pressure in die cavity gradually increases, and finally reaches overflow valve
During setting value, the water flowed out from the water side of water pump is flowed to directly from drainpipe discharge after overflow valve, positioned at the type of piston underside
The water of intracavitary is not further added by, piston no longer upward sliding.
Then the raw material of compacting carbon brush is put into the die cavity above piston, and makes drift downward.Drift makes piston
Slide downward, the water in die cavity are compressed, the pressure increase in die cavity, after the pressure in die cavity is more than the preset value of overflow valve,
Water in die cavity is discharged at drainpipe, so being eventually positioned at the pressure and overflow valve of the die cavity of piston underside and the intracavitary that cools
Setting value it is identical.Then drift is made to move upwards, because now piston is located at mold bottom, now repulsive force is minimum, so
Water pump can continue the water-filling into the die cavity below piston, piston upward sliding, carbon brush be pushed up.It is upward in piston
During slip, repulsive force gradually increases, and last piston is in itself and the gravity of electromagnet or spacing magnet, Yi Jipai
The pressure in die cavity is set to keep equal with the setting value of overflow valve in the presence of repulsion, piston is in poised state.In whole mistake
Cheng Zhong, water is all filled in the die cavity of the mould below cool chamber and piston, water contacts with mould side wall, is produced in pressing process

This programme has the beneficial effect that：（One）Overflow valve connect with positioned at the die cavity of piston underside, can keep cooling chamber with
The pressure of die cavity in communication, when drift moves upwards, piston reduces to the downward pressure of water, and water pump can be to die cavity
Water is inside filled with, makes piston upward sliding, so as to release compressing carbon brush, is easy to the taking-up of carbon brush.
（Two）In piston upward sliding, because electromagnet or spacing magnet are fixed on piston lower surface, so electromagnetism
The distance between iron and spacing magnet shorten, repulsive force increase, so piston increases the pressure for entering the water in die cavity, die cavity
Interior water is increased by compression degree, the pressure increase in die cavity, and the pressure in die cavity is when reaching the setting value of overflow valve, water pump
The water-filling into die cavity can not be continued, so piston will not continue to rise, therefore piston will not be deviate from out of mould.
（Three）When drift moves upwards, water pump can into the die cavity below piston water-filling, now water inflow type
Intracavitary, the water of inflow can enter cooling intracavitary, and current are formed in cooling chamber, because the water of inflow does not absorb heat, thus it is warm
Spend it is relatively low, the relatively low water of temperature enter after cooling intracavitary with absorb heat after the elevated water of temperature mix, make cooling intracavitary
The temperature of water reduces, and it is more preferable can to absorb more heat cooling-down effects.
（Four）When drift is pressed downward piston, overflow valve can avoid the pressure of the die cavity and the intracavitary that cools below piston
Height of continuing rising is insisted on, the elevated pressure life deformation of mould internally is then avoided, further extends the mold use life-span.
Preferred scheme one, as the further improvement to base case, electromagnet is ring-type, and is fixed in frame；Limit

Collection, water pump can continue to extract out in the water in storage tank, in this way, water can circulate at storage tank, die cavity and water pump, reduce
The waste of water, can be reduced also more environmentally-friendly while cost.
Preferred scheme three, as the further improvement to preferred scheme two, mold cavity bottom is further fixed on multiple supports
Post, the height of support column are more than or equal to the thickness of spacing magnet.Piston when sliding down to mold bottom in the presence of drift,
Support column is against piston lower surface, can avoid being fixed on the spacing magnet stress of piston lower surface, then avoid spacing magnet
It is damaged.Secondly, support column can also play a part of support to piston, avoid piston from being deformed in the presence of drift,
It is even cracked, extend the service life of piston.
