Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the present invention are described in detail:
The element antenna mould of this employing model casting is made up of the fixture of element antenna a15 and the fixture of element antenna b16; The fixture of described element antenna a15 is made up of patrix a1, counterdie a2, mandrel a3, mandrel b4, patrix a1 is placed in above counterdie a2, open between patrix a1 and counterdie a2 and be shaped with two orthogonal molten chamber a7, in two molten chamber a7, be placed with mandrel a3 and mandrel b4 respectively; By running channel a6 UNICOM between two molten chamber a7, running channel a6 is manufactured with casting hole a5; The fixture of described element antenna b16 is made up of patrix b8, counterdie b9, mandrel c10, mandrel d11, patrix b8 is placed in above counterdie b9, open between patrix b8 and counterdie b9 and be shaped with two orthogonal molten chamber b14, mandrel c10 and mandrel d11 is placed with respectively in two molten chamber b14, by running channel b13 UNICOM between two molten chamber b14, running channel b13 is manufactured with casting hole b12.
Described molten chamber a7 and the profile of element antenna a15 match; Described molten chamber b14 and the profile of element antenna b16 match.The inwall spacing of described mandrel a3 and the outer wall of mandrel b4 and molten chamber a7 equals the wall thickness of element antenna a15; The inwall spacing of described mandrel c10 and the outer wall of mandrel d11 and molten chamber b14 equals the wall thickness of element antenna b16.
The method that the element antenna Mould Machining element antenna a15 of this employing model casting and element antenna b16 replaces machining to weld by the mode of casting, cost-saved, reduce processing capacity and difficulty of processing.If but adopt general cast and die casting mode, because the structure of element antenna part is comparatively complicated, dimension precision requirement is high, general forging type all can not meet the requirement of dimensional accuracy, therefore the method casting that model casting is shaping is adopted, to ensure the requirement of parts size precision, and reduce processing capacity.
The casting technique of the element antenna mould of this employing model casting adopts metal die to inject paraffin, forms wax base, utilize wax base to manufacture formwork as core rod, dewax in high temperature furnace, burns shell.Melting liquid aluminium pressure casting is shaping in a vacuum furnace, follow-uply obtains shaping workpiece through operations such as past formwork, hydraulic sand blasting, cutting, polishing, heat treatment for solidification.In order to ensure the fineness of surface of the work, adopting metal die when making wax base, making shaping paraffin wax base have higher fineness, and then improving the workpiece surface quality of founding.Metal die base process is (for element antenna a15, element antenna b16 is identical with it): patrix a1 and counterdie a2 bolt lock are loaded on one, insert mandrel a3 and mandrel b4 in two lateral aperture respectively; The metal die assembled is loaded wax injector, in metal die, injects wax liquid from casting hole a5, after to be solidified, mandrel a3 and mandrel b4 is extracted out, unclamp bolt, patrix a1 and counterdie a2 is thrown off, take out wax base.
The defect such as pore, slag inclusion is very easily produced, especially for thin wall component during casting.Adopting when casting high-temperature vacuum furnace to carry out, can air be completely cut off, ensure the circulation of aluminium liquid, decrease the defect such as pore, slag inclusion to greatest extent, ensure that the quality of product.
The production process of the element antenna mould of this employing model casting is as follows:
1. manufacture and design metal wax injection mould according to the version of workpiece;
2. utilize wax injector to metal die casting, wax base processed;
3. die sinking, repairs wax base;
4. according to wax base molding shell, air-dry;
5. the formwork of parcel wax base is put in high temperature furnace and dewaxes;
6. formwork is put into high-temperature vacuum furnace to pour into a mould;
7. shelling after cooling, sorting fabricated part.
After element antenna is come out of the stove, scraped by artificial shovel, blast cleaning process, can ensure that unit antenna surface is smooth, tissue and mechanical performance change little, be out of shape little, accurately, outward appearance is beautiful, and total quality is good for processing dimension.The complete rigors that can reach manufactured wireless information device.
Cyclic damp heat test
According to army's mark requirement, element antenna is carried out cyclic damp heat test, and the cycle is 48 hours, and cast(ing) surface keeps metallic luster, and corrosion-free phenomenon occurs.
Compactness checks
Carry out air test to element antenna, when being filled with 0.08MPa atmospheric pressure in element antenna, do not leak air phenomenon.Air test shows, its compactness is completely up to standard.
Cost comparisons
Machining cost and model casting Cost comparisons are as following table 1:(single-piece)
Can be found out by table 1, model casting single-piece unit antenna body manufacturing expense is only 60% of original weld parts machining single-piece unit antenna manufacturing expense.In production in enormous quantities, the advantage of model casting is more obvious.
The element antenna that this employing fusible pattern mode is cast is made up of element antenna a15 and element antenna b16 two parts, element antenna a15 and element antenna b16 all adopts model casting shaping, the plug at element antenna a15 two ends adopts and is spirally connected, and assembles after machined.Whole processing, assembling process eliminate welding sequence, avoid welding deformation, effectively raise the dimensional accuracy of product, improve production efficiency.
The above is preferred embodiment of the present utility model, above-mentioned illustrating does not do any pro forma restriction to flesh and blood of the present utility model, any simple modification that person of an ordinary skill in the technical field has done above detailed description of the invention according to technical spirit of the present utility model after having read this description or distortion, and the technology contents of above-mentioned announcement may be utilized to be changed or be modified to the Equivalent embodiments of equivalent variations, all still belong in the scope of technical solutions of the utility model, and do not deviate from essence of the present utility model and scope.
