Abstract

The invention discloses a novel die-casting method for cooling fins. The method comprises the steps of firstly, manufacturing a metal part provided with a plurality of cooling fin blades and a base in an extruding and forming mode; then embedding one or more metal parts into a die; secondly, adding metallic solutions, and casting one or more metal parts into cooling fins through the die-casting method. By means of the novel die-casting method for cooling fins, the manfucturing cost of the die can be reduced, machining time cost by utilizing the die is shortened, and the production efficiency of die casting is increased.

Description

A kind of new fin pressure casting method
Technical field
The invention belongs to microdiecast field, be specifically related to a kind of new fin pressure casting method.
Background technology
Bag pressure casting individual blade is penetrated in current employing, again multiple blade is assembled into overall method, the global consistency of the fin formed is poor, mould exists the groove of a large amount of dress blade, opening period is longer, and die life is short, the bonding bad frequency of individual blade die casting is higher, and process time is longer, cost is higher, and follow-uply also will design relevant assembly and assemble.
Summary of the invention
The object of this invention is to provide one and can reduce fin production cost, improve the fin pressure casting method of fin production efficiency.
For above-mentioned purpose, the technical solution used in the present invention is as follows: a kind of new fin pressure casting method, comprises the following steps:
(1) by squeezing type forming method, the metalwork with multiple fin blade and a pedestal is obtained;
(2) be mounted in mould by one or more for above-mentioned metalwork;
(3) then add metallic solution, by the method for die casting by one or more metalwork die casts, be fin.
As the further optimization of such scheme, described metalwork material is aluminium or copper or iron.
As the further optimization of such scheme, the base perimeter in above-mentioned steps (1) is provided with hole or/and groove.
The pressure casting method of above-mentioned steps (3) comprises the following steps:
(1) by die casting machine, metallic solution is filled in mould;
(2) metallic solution is by the hole of metalwork base perimeter or/and groove, is wrapped up by metalwork in mould;
(3), after metallic solution cooled and solidified, merge between metalwork, i.e. fin.
As the further optimization of such scheme, described hole is oval, and described groove is rectangle.
The beneficial effect main manifestations of a kind of new fin pressure casting method of the present invention is: can reduce Mold Making cost, shorten the time utilizing Mould Machining, improve Die Casting efficiency, fin stability is better with heat radiation uniformity, the assembly needed for assembling can be saved simultaneously, greatly reduce the cost of aft-loaded airfoil.
Accompanying drawing explanation
Fig. 1 is the schematic cross-section of the fin obtained by the present invention.
Fig. 2 is the partial schematic diagram of the metalwork obtained by the present invention.
Wherein 1 is fin blade, and 2 is metalwork pedestals, and 3 is cooling fin fin bases that metallic solution is formed, and 4 is grooves, and 5 is screwed holes.
Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, the present invention will be further described.
As illustrated in fig. 1 and 2, a kind of new fin pressure casting method, first by squeezing type forming method, obtains the metalwork with multiple fin blades 1 and a pedestal 2; Then be mounted in mould by one or more for above-mentioned metalwork; Next adds metallic solution, by the method for die casting, one or more metalworks is cast into fin.The position that pedestal 2 periphery on multiple metalwork is combined with metallic solution is designed to groove structure, multiple metalwork is engaged in a mould, by die casting machine, metallic solution is filled in mould, solution is by gaps such as blade 1 upper grooves 4, the part (i.e. groove 4) be exposed at by radiator shutter in mold core is wrapped in the inside, then, after metallic solution solidifies, metallic solution and radiator shutter just combine.
In the present embodiment, when making mould, only need avoid place corresponding to section bar by the mode of Linear cut, be put in advance in mould by the radiator shutter 1 with pedestal 2 made, the position that radiator shutter 1 pedestal 2 is combined with metallic solution is groove 4 structure or boss structure or pore space structure.
By reference to the accompanying drawings the preferred embodiment for the present invention is explained in detail above, but the invention is not restricted to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, can also make a variety of changes under the prerequisite not departing from present inventive concept.
Do not depart from the spirit and scope of the present invention and can make other changes many and remodeling.Should be appreciated that and the invention is not restricted to specific embodiment, scope of the present invention is defined by the following claims.
