Further, the first shunt bridge 131, the second shunt bridge 132, the 5th shunt bridge 135, the 6th shunt bridge the 136, the 9th
The width of shunt bridge 139 and the tenth shunt bridge 1310 is 10 ~ 15mm.
Preferably, the first shunt bridge 131, the second shunt bridge 132, the 5th shunt bridge 135, the 6th shunt bridge 136, the 9th point
The width for flowing bridge 139 and the tenth shunt bridge 1310 is 12mm.
First shunt bridge 131, the second shunt bridge 132, the 5th shunt bridge 135, the 6th shunt bridge 136, the 9th shunt bridge 139
Width with the tenth shunt bridge 1310 is 18 ~ 22mm.
Preferably, the width of third shunt bridge 133, the 4th shunt bridge 134, the 7th shunt bridge 137 and the 8th shunt bridge 138
For 19.8mm.
So the width of each shunt bridge is optimized, guarantee the intensity of mold core print and has adjusted the flowing speed of metal
Degree, so that flow rate of metal is more uniform.
Lower die includes choker bar, and having a size of 80*6*3 ~ 5mm, choker bar corresponds to be set choker bar at product moulding hole
It sets, includes the first choker bar 210, the second choker bar 220, third choker bar 230 and the 4th choker bar 240, the first choker bar,
Second choker bar, third choker bar and the 4th choker bar are located at profile upside, right side, downside and left side.
First choker bar 210, the second choker bar 210, third choker bar 230 and the 4th choker bar 240 cross sectional shape with
The cross sectional shape of corresponding position profile matches.
In first choker bar 210, the second choker bar 210, third choker bar 230 and the 4th choker bar 240 and upper mold 100
Tap hole inner wall is spacing setting.
Choker bar will guarantee that certain effective distance, in this way guarantee metal can be flowed into smoothly with the inner wall of corresponding tap hole
It die hole and is filled up completely, guarantees its density and line position size and surface quality, meet the requirements.
First choker bar 210, the second choker bar 210, third choker bar 230 and the 4th choker bar 240 are to protrude from down
Protrusion except mold forming end face, the first choker bar 210, the second choker bar 210, third choker bar 230 and the 4th choker bar 240
With lower die profile end face 3 ~ 5mm of distance.
Preferably, the height of the first choker bar 210, the second choker bar 220 and third choker bar 230 is 3mm, the 4th choked flow
The height of block 240 is 5mm., the deformation very little that profile generates everywhere at this time, material flowing is more uniform at profile cross-sectional exit.
Reasonable choked flow block structure is used in lower die, the flow velocity of metal, is conducive to metal when adjustment can be assisted to squeeze
Molding.
Upper mold 100 flows into the inflow angle in tap hole with a thickness of 81mm, lower die 200 with a thickness of 120mm, metal in mold
250 be 8 ~ 12 °.
Preferably, the inflow angle 250 that metal flows into tap hole is 9 °, keeps metal flow rates more uniform, flows into
Angle 250 is related with profile wall thickness at corresponding die hole, and the inflow bigger flow velocity of angle 250 is about slow, and wall thickness is thinner, and on the contrary then wall thickness is got over
It is thick.
Using the tap hole design and shunt bridge design of special shape, when flowing extruding metal, each position of profile
Flow rate of metal is in a basic balance, to guarantee that squeezing out profile is fully achieved design requirement；
The angle of tap hole is flowed into using the upper mould thickness, shunt bridge width and metal of optimization, reduces squeeze to greatest extent
Pressure ultimately facilitates the wall thickness tolerance for guaranteeing inner cavity profile to guarantee the intensity of mold core print；
In lower die 200 use reasonable choked flow block structure, auxiliary adjustment squeeze when metal flow velocity, be conducive to metal at
Type.
The beneficial effect of new energy battery pack lifting lug profile extrusion die of the present invention is:
Intermediate distributary hole is increased, and shunt bridge, limited block and metal fluid inlet angle are optimized, mold is repaired by 3 die trials
After mould, profile can reach design requirement, and the deformation that profile generates everywhere is small, and flow rate of metal is more uniform when profile extrusion, energy
Enough steady productions greatly reduce die trial and repair a die the time, reduce die trial expense, so as to shorten entire project exploitation when
Between.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
