Alloy and molding babinet.
In the utility model, in specific implementation, the babinet of 1 the being integrated casting of babinet main body, by ZL102
Cast aluminium alloy gold carry out monoblock cast, one-pass molding.
It is described vertical, it is necessary to which explanation, the cross reinforcing 3 are the metal ribs of cross direction profiles in the utility model
To the metal ribs that reinforcing rib 4 is genesis analysis.It should be noted that the waling 4 is in a unlimited number in shown in Fig. 1
Four, according to the needs of user, it can also be any a plurality of, and 3 optional position of a plurality of cross reinforcing is connected.
In the utility model, in specific implementation, the cross reinforcing 3 and waling 4 and the babinet main body 1
Inside pass through low-pressure casting process and realize integrated casting.
In the utility model, the symmetrical fixed cast in the left and right sides of the babinet main body 1 forms four pairs of babinet lifting lugs
2, in specific implementation, according to the actual size of babinet main body 1 and the needs of user, any multipair babinet lifting lug can also be set
2。
In specific implementation, each babinet lifting lug 2 and the babinet main body 1 preferably integrated casting, structure
Intensity is high.
In specific implementation, positioned at the size of the babinet lifting lug 2 of two middle side parts of the babinet main body 1, more than positioned at described
The size of the babinet lifting lug 2 of the both sides other positions of babinet main body 1 so that have more to the middle part of the babinet main body 1
Strong supporting role, further improves the shockproof effect of babinet main body 1.
In specific implementation, the bottom of each babinet lifting lug 2 is provided with the reinforcing rib of the strip of cross direction profiles, described
Reinforcing rib and the 1 integral low pressure casting of babinet main body, so as to supporting box lifting lug 2, further enhance babinet
Degree of being connected firmly between lifting lug 2 and babinet main body 1, prevents babinet lifting lug 2 to be broken after prolonged use.
In specific implementation, the babinet lifting lug 2 is used for and needs the vehicle frame of New-energy electric vehicle to be mounted to be fixedly connected
Together.
In the utility model, in specific implementation, the bottom outer surface of the babinet main body 1 is coated with polyvinylchloride
Coating (i.e. armoring).
In the utility model, in specific implementation, the babinet main body 1 is preferably the babinet crossed by electrophoretic process.
It should be noted that in the utility model, the casting technique of the babinet main body 1 is briefly described as：Babinet master
The preheating of mould needs the temperature of priority control mould, and die lubricant spray painting control main points are in mould inner surface roughness, aluminium
The liquid melting of alloy removes component ratio in impurity analysis aluminium alloy solution, is poured into mould, it is ensured that (aluminium closes pouring temperature
Golden fluid temperature and mold temperature) it is qualified, after babinet main body spray is cooled and shaped, its surface quality check clear
Reason, ball blast carry out spray surface roughness processing, then carry out the inspection of blank apparent size and the spray of casting
Mechanical performance test.
It should be noted that in the utility model, the processing technology of the babinet main body 1 is briefly described as：To babinet
The cast blank part of main body carries out line processing, roughing end face, and critical process is by hydraulic pressure and airtight detects babinet
Casting whether there is casting flaw, line processing, and clamping enters digital control processing critical process, reconditioning school is carried out to babinet after processing
Just, finally by electrophoresis process to Battery case main body be surface-treated and application.
For the utility model, in design, fully take into account the general boundary dimensions of Battery case main body it is larger (such as
About 1905*1150mm) so that casting area is big, outer shape and inner mold is complicated causes that wall thickness is locally uneven, need to hold
(it can need to be shaken by dynamic high load capacity in the state of about 340kg is loaded by the vehicle body parts national standard of national authentication qualification
The test such as move, extrude, falling), at the same time, sealing performance requirement also needs to reach IP67 protection level requirements.In addition, in the choosing of material
Selecting has higher requirement, by the analysis repeatedly to multiple material and verification after, the utility model finally use the trade mark for
The cast aluminium alloy gold of ZL102 carrys out casting box main body as raw material.
According to casting technique, be determined that the wall thickness of babinet main body is at least 5mm under the premise of light-weighted, and to structure into
Adjustment is gone, has required high position to reserve allowance in sealing surface and fitting surface equally accurate and be easy to following process.Babinet master
Body has the wall thickness of 5mm, greatly improves the anti-impact force and intensity of cast aluminium battery case, and due to cast aluminium alloy gold ZL102
Density be only 2.70g/cm3, far below existing Battery case main body used by iron plate 7.85g/cm3Density, therefore,
In the utility model, its babinet main body manufactured has still achieveed the purpose that loss of weight.In follow-up processing, by adding with higher
The numerically-controlled machine tool of work precision carries out comprehensive secondary operation to the mounting surface of product and mounting hole position, can further improve product
Precision.
Compared with prior art, new cast aluminium Battery case provided by the utility model, has following beneficial effect：
