Detailed description of the invention
In order to be illustrated more clearly that technical scheme, below in conjunction with drawings and Examples, the technology to the present invention
Scheme is further elaborated, it should be apparent that, describing below is only some embodiments of the present invention, for this area
From the point of view of those of ordinary skill, on the premise of not paying creative work, it is also possible to obtain other reality according to these embodiments
Execute example.
Referring to figs. 1 through Fig. 5, a kind of annular choke coil antenna base manufacture method, by the aluminium alloy liquid of molten condition
Inject mould and carry out low pressure or gravitational casting obtains the blank of annular choke coil antenna base, then by blank CNC machine
Carry out polish, remove unnecessary material, then carry out surface process, thus obtain annular choke coil antenna base；Wherein,
Described aluminium alloy liquid includes A356 aluminium alloy and fine aluminium, and the quality accounting of described fine aluminium is 4%～6%.Concrete, melted
The quality accounting of the fine aluminium in aluminium alloy solution is specifically as follows 4%, 4.5%, 5%, 5.5%, 6%, according to product type chi
The accounting that very little and casting environment different choice is concrete.Can make by adding the fine aluminium of appropriate accounting in aluminium alloy solution
Obtain product and obtain good surface effect in follow-up anodic oxidation operation, improve product quality.
Concrete, as a example by low pressure casting, by mo(u)ld top half 3 and mo(u)ld bottom half 4 mould assembly on air injection machine of mould, by aluminium alloy
Liquid is placed in crucible 5 or the hermetically sealed can of sealing, and is passed through dry in crucible 5 or hermetically sealed can by compressed air inlet 6
Dry compressed air so that aluminium alloy liquid is risen by stalk 7, and the die cavity 8 of mould is steadily entered by cast gate, and protect
Hold the gas pressure in crucible 5 or hermetically sealed can, until till the blank of annular choke coil antenna base solidifies completely, so
After release the gas pressure in crucible 5 or hermetically sealed can again so that in stalk 7 not solidified molten metal backflow crucible 5 or
In hermetically sealed can, then by cylinder open form the blank of releasing annular choke coil antenna base.
There is the flaw defects such as burr, it is thus achieved that at the bottom of annular choke coil antenna on the blank of annular choke coil antenna base
After the blank of seat, blank is placed in CNC machine and carries out polish, remove the flaw such as blank of annular choke coil antenna base
Defect, and be removed the excess stock of the blank of annular choke coil antenna base obtaining the outer mold surface preset, and
After carrying out surface process, thus obtain standardized annular choke coil antenna base.Above-mentioned manufacture method can be used
In 2D annular choke coil antenna base and the manufacture of 3D annular choke coil antenna base；Wherein, 2D annular choke coil
The conjugate meshing of antenna base highly consistent, overall in flat structure；The height of the conjugate meshing of 3D annular choke coil antenna base
Degree difference, the increasing height from outer ring to inner ring, overall in tower structure.
The present invention is different from common injection molding type Hpdc by employing, the injection die cast that common application is relatively broad
Technique is in addition to the cost of manufacture of mould is high, and the deflection after foundry goods molding is big, and castings material loosens, and internal porosity is many, by force
Spend low, substantially less than the requirement of high-end product.And application practice of the present invention is strong, raw material reduces at double, and man-hour reduces, and produces
Quality is more stable, controlled, and production efficiency is greatly improved.
In one embodiment, mould uses high strength steel to make, the mold cavity 8 deformation quantity in casting process
Little, the dimensional accuracy of the blank of casting annular choke coil antenna base out is high, it is ensured that needed for following process process
Dimensional requirement.
In one embodiment, blank uses T6 stiffened heat treatment and Shot Blasting so that raw-material hardness carries
Height, to improve the hardness of blank, and discharges blank internal stress, reduces the deformation quantity of product, the circle after carrying out CNC machine processing
The degree of deformation of toroidal chokes antenna product is minimum, so that the quality of annular choke coil antenna product and precision are further
Improve.
In one embodiment, the dimensional accuracy of foundry goods is limited, needs that foundry goods is carried out in CNC machine subsequent fine and adds
Work, therefore, the overall dimensions of blank leaves the surplus being easy to the processing of follow-up CNC machine.
In one embodiment, the base of annular choke coil antenna base is provided with loss of weight portion 1, and loss of weight portion 1 can be once
Casting, it is not necessary to follow-up CNC machine is processed.
In one embodiment, the bottom even of annular choke coil antenna base is laid with a plurality of reinforcement 2, thus
Mould forms a plurality of flow channel so that liquid metal liquid can preferably be filled into the die cavity of mould in casting process
In 8, and the intensity of sustainable product after casting, make product indeformable.
In one embodiment, the size of the die cavity 8 of mould is more than the maximum profile of annular choke coil antenna base
Size so that various sizes of annular choke coil antenna base can be with sharing die Foundry Production blank.As shown in Figure 4,
In accompanying drawing 4, the dotted line of different proportion represents the outer mold surface of the annular choke coil antenna base of different model, by using big chi
Very little die cavity 8 so that the location overlap at the relative center of the annular choke coil antenna base of multiple models together, Ji Gexing
Number annular choke coil antenna base use same mould make blank, due to the annular choke coil antenna of each model
The location overlap at the relative center of base together, therefore has only to specifically go out drawing according to annular choke coil antenna base
Use CNC machine to remove surplus, i.e. several prods can use same mould to produce blank, and a mould is produced
The blank come may be used for producing the choke coil antenna base of different size brand, has greatly saved production cost.
In one embodiment, when the conjugate meshing wall thickness of annular choke coil base is bigger, for the aluminium alloy of casting
A356 aluminium alloy composition in liquid can use 6061 aluminium alloys to substitute, and 6061 aluminium alloys are cast as big wall thickness structure
Type is effective, it addition, there is preferable anodized surface treatment effect after 6061 aluminium alloy molding.
The present invention manufactures 2D annular choke coil antenna base and 3D circle by application low pressure (or gravity) casting technique
The blank of toroidal chokes antenna base, raw material reduces more than 80%, and the waste material simultaneously processing generation also reduces more than 80%,
Machining period reduces more than 60%, and manufacturing procedure decreases roughing operation the most accordingly, and product quality is more stable, controlled, raw
Product efficiency is greatly improved, owing to the blank of Foundry Production uses T6 stiffened to process so that blank hardness improves, and releases blank
Material internal stress, after CNC machine is processed, deformation of products degree is minimum, so that the quality of product and precision improve further.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For Yuan, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should
It is considered as protection scope of the present invention.
