The basic idea of the invention is that in production, cause the reason of squeezing rotten mould predominantly mold sky knife processing partially and
Die working length unreasonable structure causes under feeding when extruding and force unbalance and generates inclined tooth and broken teeth；The application is logical
Cross optimization mold structure design and improve mold processing quality this 2 aspect can be effectively improved rotten modulus problem,
With reference to the accompanying drawing, the radiator mould work belt, work belt processing method and its radiator mould is described in detail
It is described in detail.It is the part that entire profile is most difficult to discharging since toothed portion wall thickness is thin, is the entire profile work belt of design
Basis.
Radiator mould work belt as depicted in figs. 1 and 2 may include matrix 100 and be arranged on matrix 100 uniformly
Multiple gear pieces 200 of distribution, and the cross-sectional shape in 100 first face 101 of matrix is arc.Since two sides tooth pitch is from Center of Pressure
Far, flow rate of metal is slow, and it is fast to achieve the effect that two sides tooth discharges than center tooth, makes to squeeze material head and shows that bottom is slightly fast, two sides
Tooth is fastly slightly rational state it is necessary to the work belt width that shortens the position than center tooth, therefore, by the first face 101 of matrix 100
Be arranged to cambered surface, meanwhile, in this way design so that side toothed portion and center tooth portion smooth linking, its flatness it is good, mold squeeze
When, stress balance, each section discharging speed is identical, can Homogeneous charge, reduce when due to squeezing under feeding and stress not
It balances and generates inclined tooth and broken teeth phenomenon.
Also, further, the longitudinal section in 100 first face 101 of matrix and the bottom surface 102 of matrix 100 be at predetermined angle,
In, predetermined angle is 65 °~85 °, such as α can be with are as follows: 65 °, 70 °, 75 °, 80 °, 85 °.The slurry made is designed in this way along slope
Face is uniformly climbed, and each section compression of matrix 100 is equal, avoids generating inclined tooth and broken teeth phenomenon.
Specifically, the height of the longitudinal section of matrix 100 and the width ratio of longitudinal section are 1.5~2.0.
Wherein, the height of the longitudinal section of matrix 100 is 12.9mm, and the width of longitudinal section is about 23.5~26mm.
Also, in order to form any of the effect that the flow rate of slurry of teeth portion slows down gradually from bottom to top, multiple gear pieces 200
The width of gear piece be 0.8~1.0 times of thickness.The altitude range of any one gear piece is 100~150mm or more, any one gear piece
Thickness range is 1.2~6mm or more.

A kind of processing method of radiator mould work belt.
In order to improve the precision of processing, reduce error, processing method includes carrying out electric spark roughing and electricity to work belt
Spark finishing, electric spark roughing include empty knife correction, since tooth tip position tapping flowrate is slow, and are produced from a large amount of molds
It is found in journey, most of to be all upturned in discharging, tooth tip 300 is empty, and knife is small will fill in mould, so increasing tooth tip portion as far as possible
The empty knife of position, therefore, the pre- high 2.5~4.0mm surplus of the empty knife of tooth tip 300,301 general spacing of between cog inside are small, in order to guarantee tooth
Between die steel intensity, minimize between cog sky knife, therefore 301 empty knives are pre- on the inside of between cog wide stays 0.5~0.7mm surplus, tooth
Outside 302 is similar with tooth tip portion, increases empty knife size as far as possible, therefore 302 empty knives are pre- on the outside of tooth wide stays 1.0~2.0mm surplus, tooth
Work belt 1 length in bottom is big, is able to bear biggish power, and empty knife to be designed somewhat larger, to guarantee that profile table will not be scratched
Face influences profile presentation quality, therefore the empty knife depth of tooth root 303 stays 1.0~2.0mm surplus.
When electric spark roughing, the length of every processing 0.3mm work belt 1 can detecte and whether judge gear piece spacing
Equal to predetermined gear piece spacing, if gear piece spacing is equal to predetermined gear piece spacing, continue to carry out electric spark roughing to work belt 1；
If gear piece spacing is more than or less than predetermined interdental space, electrospark electrode returns to a detection position to work belt 1 again
Processing.
And in order to improve the precision of processing, when electric spark roughing, the length of every processing 8.0~10.0mm work belt 1
Degree, can detecte and judge whether empty knife spacing is equal to pre- knife spacing of leaving a blank, if empty knife spacing is equal to knife spacing of leaving a blank in advance, after
It is continuous that electric spark roughing is carried out to work belt 1；If empty knife spacing is more than or less than knife spacing of leaving a blank in advance, electrospark electrode is returned to
Upper detection position re-works work belt 1.
The rough machined electric current of electric spark is 13.0~18.0A, and the electric current of electric spark finishing is 10.0~13.0A.
For example, rough machined electric current be 13.0A, 14.0A, 16.0A, 18.0A, electric spark finishing electric current be 10.0A,
11.0A,12.0A,13.0A.Good surface smoothness is obtained using the small energy of electric current, it is highly dense since low current process velocity is slow
Tooth mold can also mill out work belt 1 when slightly beating in advance, can also be improved processing efficiency in this way.
Embodiment 4: empty knife correction: the pre- high 2.5mm surplus of the empty knife of tooth tip 300, the empty pre- width of knife between cog inside 301 stay 0.5mm
Surplus, the empty pre- width of knife in tooth outside 302 stay 1.0mm surplus, and the empty knife depth of tooth root 303 stays 1.0mm surplus, the rough machined electricity of electric spark
Stream is 13.0A, and the electric current of electric spark finishing is 10.0A.
Embodiment 5: empty knife correction: the pre- high 4.0mm surplus of the empty knife of tooth tip 300, the empty pre- width of knife between cog inside 301 stay 0.7mm
Surplus, the empty pre- width of knife in tooth outside 302 stay 2.0mm surplus, and the empty knife depth of tooth root 303 stays 2.0mm surplus, the rough machined electricity of electric spark
Stream is 18.0A, and the electric current of electric spark finishing is 13.0A.
A kind of radiator mould, as shown in figure 3, including work belt 1, deflector 2 and die face 3, work belt 1 is arranged in water conservancy diversion
Between plate 2 and die face 3, first face 101 its cross-sectional shape adjacent with deflector 2 of matrix 100 is cambered surface, the first face 101
Longitudinal section and the bottom surface 102 of matrix 100 are at predetermined angle, wherein predetermined angle is 65 °~85 °.
The present invention proposes a kind of radiator mould work belt, work belt processing method and its radiator mould, passes through optimization
The structure of work belt, empty knife, guarantees the processing quality of electric spark process, reduces under feeding when squeezing and force unbalance and produces
Raw inclined tooth and broken teeth improve the die trial success rate of radiator mould, so realize reach 90% or more die trial success rate and mention
