Description
Technical field
The present invention relates to a kind of processing method of aluminium extracting mold, especially a kind of in order to extrude the processing method of the aluminium extracting mold that high density, high multiple aluminium radiator use, belong to the Mold Making technical field.
Background technology
Aluminium extracting mold not only can be in order to extrude articles for daily use such as common aluminium tube, aluminium door and window, also can be in order to extrude higher computer radiator of technology content and optical measurement body etc.Can there be any technology barrier hardly in the aluminium extracting mold of using in order to daily lifes such as extruded aluminum tubing, aluminium door and window materials for processing, even in order to process the mould that early stage aluminium matter computer radiator is used, because it is not high that the radiating efficiency of early stage computer radiator requires, spacing between the radiating fin is big, (computing formula of multiple is multiple: the width=multiple of radiating fin height/stressed support portion) also little, the force-bearing situation of mould is good, and the pressure in the time of can supporting extruding reaches 120kg/cm
2Can not cause mould in the same old way and reverse mould occur, therefore, make such mould and still can not have technical difficulty.
Raising and sophistication along with CPU floating-point operation speed, taking up space less as much as possible and improving under the requirement of radiating efficiency, under the situation in overall volume that can't strengthen radiator and space, can only consider to the spacing of dwindling between the radiating fin, increase area of dissipation so that promptly increase density, make it to improve radiating efficiency by increase radiating fin quantity.And, require harsh radiating fin for heat radiation, except dwindling the spacing between the fin, be attended by high multiple requirement toward contact, therefore, having only close and elongated fin is that the high multiple fin of high density could satisfy and occupies the instructions for use that the space is little, radiating efficiency is high, but, the elongated fin of healing easily subsides because of root structure support force shortcoming heal when extruding, and lateral thrust occurs and causes the support portion to rupture and then mould is scrapped, thereby the processing of this type of mould has been proposed challenge.
Differentiation between high-end computer radiator and the low-grade computer radiator is normally weighed with the multiple of the fin of radiator, and the processing complexity of its mould also is used as judgment standard with this multiple.General industry all can with interior molding ability at multiple 12, but, as want to reach and make mould be ensured that it then is processing cost, difficulty of processing, process time all to be very headachy that smooth volume production requires in the face of the mould of computer radiator more than 12 times.
Industry knows that all the aluminium extruded mould that processing aluminium extruded material is used all need be embodied as the shape hole and escape the hole on mould, and the computer radiator of aluminium extruded type is as the same.The characteristic of aluminium stream for be heated to 450～550 ℃ promptly softening be a kind of plastic material, see through the shaped hole extrusion molding again, and the shape area of escaping the hole must be greater than shaped hole, extruding smoothly when guaranteeing to extrude, so certainly exist a transition region between fugitive hole and the shaped hole, this transition region promptly is so-called work zone, can have one to work by following explanation and understand more fully.Shaped hole is to ensure that aluminium stream is shaped, and is smooth and easy the extruding of aluminium material after guaranteeing to be shaped and escape the hole.Do not have the hole of escaping if having only shaped hole, promptly also become shaped hole escaping the hole, the suffered frictional resistance of passage of aluminium stream process can increase so, the aluminium material can't be extruded, even reverse mould can occur.According in such knowing altogether, know together, often need on mould, design the Bearing face that the custom with moulding function is referred to as the work zone just.Fig. 1 provides is the positive situation of the shaping mould that being used in the prior art extrudes computer radiator, and Fig. 2 is the partial structurtes figure of Fig. 1, and obvious on pedestal 7 have the 4th work zone 8, and Fig. 3 is the partial enlarged drawing of Fig. 1.Resulting shown in Figure 4 by coming to analysing and observe of Fig. 3, also be that the both sides of each radiating fin 9 have second work zone 4 at the middle part of each radiating fin 9; And then, also have the 3rd work zone 5 at the end points of each radiating fin 9 by shown in Figure 5; More and ground by shown in Figure 6, have first work zone 6 equally at the base portion of each radiating fin 9, Here it is, and present processing method reflected in order to the constructional aspect of the aluminium extruded pattern that extrudes computer radiator.Specifically making step is: judge that according to the crowded type drawing that the user provided aluminium flows the flow distribution zone and also determines the die sinking pattern earlier, use the line cutting processing again, after electric spark is thick, carefully discharge is processed and obtained.From Fig. 4 to Fig. 6 as can be known, aluminium stream 1 is shaped from shaped hole 2, again from as discharge opening escape extrude the hole 3.The effect of first, second, third, fourth work zone 6,4,5,8 is the discharging speeds in order to control aluminium stream 1, if make the speed of aluminium stream 1 fast, so must be short with the Design of length of first, second, third, fourth work zone 6,4,5,8, vice versa.
Yet, because the shaped hole 2 of the shaping mould of above-mentioned aluminium extracting mold and what escape to be constituted between the hole 3 is stairstepping, so only can be applicable to that extruding radiating fin 9 is low-density computer radiator, and just seem powerless for being used for extruding highdensity radiating fin 9.Because what industry was admitted generally is respectively 3-12mm and 1.5-4mm in order to the height of the pedestal 7 of the shaping mould that extrudes highdensity computer radiator and the width of radiating fin 9, again because, owing to must produce first, second, third work zone 6,4,5 respectively in base portion, both sides, the end of radiating fin 9 as aforesaid transition region, thereby make the thickness attenuation all the more of the radiating fin 9 of thin (1.5-4.0mm) originally, cause intensity to ensure, use the intermediate frequency existing reverse mould that occurs frequently, and multiple is higher, and the reverse mould phenomenon is more serious.In addition, grow the discharge time of the above-mentioned finishing die of thick, the thin discharge processing of electric spark (needing about 24-36h), not only the time of processing mold tediously long, but also bring cost increase to conductive electrode.
Summary of the invention
Task of the present invention be to provide a kind of energy satisfy to extrude out with being able to volume production high density, the requirement of high multiple computer radiator and can be because of the processing method that reverse mould causes the aluminium extracting mold that mould is scrapped, the Mould Machining cost is low, lack process time not occurring.
Task of the present invention is finished like this, a kind of processing method of aluminium extracting mold, it may further comprise the steps: earlier according to the computer radiator shape of product shown in the drawing, judge aluminium distributions zone and determine the die sinking pattern, between radiating fin 9, form shaped hole 2 again by the line cutting processing and escape hole 3, described line cutting is the inclined plane that shaped hole between the radiating fin 92 and the direct line of hole wall of escaping hole 3 is cut into inclination, and 7 of pedestals that the base portion of the both sides of the end of radiating fin 9 and radiating fin 9 and radiating fin 9 also had shaping mould towards the one side of radiating fin 9 respectively line cut into and have first, second, the 3rd, the 4th slope K 1, K2, K3, the inclined plane of K4, first, second, the 3rd slope K 1, K2, K3 is differing from each other, and the 4th slope K 4 is identical with the 3rd slope K 3.
The size of first slope K 1 of the end of radiating fin 9 of the present invention is directly proportional with the height of the pedestal 7 of shaping mould.
The size of second slope K 2 of the both sides of radiating fin 9 of the present invention and the width of radiating fin 9 are inversely proportional to.
The size of the 3rd slope K 3 of the base portion of radiating fin 9 of the present invention and the 4th slope K 4 all is inversely proportional to the height of the pedestal 7 of shaping mould.
Size and the aluminium flow export width of first, second, third, fourth slope K 1 of the present invention, K2, K3, K4 are inversely proportional to.
The inventive method because with the shaped hole in the prior art 2, escape hole 3 and constitute stair-stepping hole shape each other and become trumpet-shaped hole shape, thereby can save in second work zone 4 of the 3rd work zone 5 of the end of radiating fin 9 and both sides and first work zone 6 of saving base portion also has the 4th work zone 8 at pedestal 7 positions; Become in the prior art and control aluminium stream 1 speed of extruding into control aluminium stream 1 speed of extruding with the slope variation on inclined plane with the length of work zone, thereby can strengthen the intensity of radiating fin 9 effectively, shaping mould can be extruded high density, high multiple computer radiator and reverse mould can not occur in the adaptive capacity place of production, prolonged the service life of mould; Directly need not resemble again and need be aided with thick, the thin discharge processing of electric spark the prior art by the moulding of line cutting processing, thus can shorten effectively mould process time, save processing cost.

The specific embodiment
In Fig. 7,, therefore do not have difference with Fig. 1 positive because this figure is the state of seeing from the front of shaping mould.
In Fig. 8, it has reflected the structure of Fig. 7, can see that the shaped hole 2 between the radiating fin 9 has been processed to the inclined-plane that tilts with the hole wall of escaping hole 3, promptly promptly form horn-likely with the aperture in the left side of this figure position on the whole with the hole tail on this right side, figure position until extending to the hole tail of escaping hole 3 from the aperture of shaped hole 2, promptly the hole tail of escaping hole 3 until arrival from the aperture of shaped hole 2 is extended to horn-like gradually or claims splayed.
In Fig. 9, Figure 10, Figure 11, Figure 12, reflected the situation that the size of the 3rd slope K 3 of the base portion of second slope K 2 of both sides of first slope K 1 of end of radiating fin 9 and radiating fin 9 and radiating fin 9 has nothing in common with each other.Specifically: second slope K 2 that figure 10 illustrates the both sides that find expression in radiating fin 9; Figure 11 illustrates first slope K 1 of the end that finds expression in radiating fin 9; Figure 12 illustrates the 3rd slope K 3 of the base portion that finds expression in radiating fin 9.For the big or small value degree of first slope K 1 of the end of radiating fin 9 is determined according to the height of the pedestal 7 of shaping mould, if pedestal 7 is highly big, so, first slope K 1 of end is also big, and vice versa.The applicant mentions in prior art, the conduct admitted of industry at present is 3-12mm in order to the height of the pedestal 7 of the shaping mould that extrudes highdensity computer radiator, size for first slope K 1 that obtains the end, explore and show through the applicant, when the thickness of pedestal 7 is 3-12mm, getting the front at radiating fin 9 tops and the first drop L1 (seeing Figure 15) between the back side is comparatively suitable for 0.6-1.2mm, the thickness T of working as shaping mould (is seen Fig. 8 like this, Figure 14) determine back (thickness T that generally is used to extrude the shaping mould of high density computer radiator is 30-50mm), so as long as just obtain first slope K 1 of end divided by thickness T with the first drop L1.Show that through further test of applicant and checking when the height of pedestal 7 was 3-5mm, getting the first drop L1 was 0.6-0.8mm, then obtained first slope K 1 of respective end portions; When the height of pedestal 7 was 5-8mm, getting the first drop L1 was 0.8-1.0mm, then obtained first slope K 1 of respective end portions; When the height of pedestal 7 was 8-12mm, then getting the first drop L1 was 1.0-1.2mm, thereby obtained first slope K 1 of respective end portions.Hence one can see that, and when the height of pedestal 7 was big more, the numerical value of the resulting first drop L1 was also big more, and first slope K 1 of corresponding end is just big more.So first slope K 1 of end is to be directly proportional with the height of pedestal 7, otherwise can influence the intensity at radiating fin 9 tops.
For the size of second slope K 2 of the both sides of radiating fin 9 be width size according to radiating fin 9 and fixed, width is big more, second slope K 2 is more little, vice versa.The applicant mentions that in prior art the width of the radiating fin 9 of industry made generally is about the scope of 1.5-4mm at present.In order to obtain rational second slope K 2 of both sides, explore and confirmation through the applicant, when the width of radiating fin 9 is 1.5-4mm, the second drop L2 (seeing Figure 15) that gets between the sidepiece at the front of radiating fin 9 and the back side is comparatively suitable for 0.25-0.65mm, like this, after the second drop L2 is determined, so as long as just obtain second slope K 2 of both sides divided by the width of radiating fin 9 with the second drop L2.Show that through the further test of applicant when the thickness of radiating fin 9 was 1.5-2.0mm, getting the second drop L2 was 0.25-0.4mm, then obtained second slope K 2 of corresponding both sides; When the thickness of radiating fin 9 was 2.0-3.0mm, then getting the second drop L2 was 0.4-0.5mm, thereby obtained second slope K 2 of corresponding both sides; When the thickness of radiating fin 9 was 3.0-4.0mm, then getting the second drop L2 was 0.5-0.65mm, thereby obtained second slope K 2 of corresponding both sides.
For the big or small value degree of the 3rd slope K 3 of the base portion of radiating fin 9 is determined according to the height of the pedestal 7 of shaping mould, and the height of pedestal 7 is big more, and the 3rd slope K 3 of base portion is more little so, vice versa.The 3rd slope K 3 for the base portion that obtains radiating fin 9, explore and draw through the applicant, when the height of pedestal 7 is 3-12mm, the front and the 3rd drop L3 (seeing Figure 15) between the back side that get the bottom of radiating fin 9 are comparatively suitable for 0.6-1.5mm, like this after the thickness T (seeing Fig. 8, Figure 14) of shaping mould is determined, so as long as just obtain the 3rd slope K 3 of base portion divided by thickness T with the 3rd drop L3.Further explore and test through the applicant, the result shows that when the height of pedestal 7 was 3-5mm, getting the 3rd drop L3 was 1.2mm-1.5mm, thereby obtains the 3rd slope K 3 of corresponding base portion; When the height of pedestal 7 was 5-8mm, getting the 3rd drop L3 was 0.9mm-1.2mm; When the height of pedestal 7 was 8-12mm, getting the 3rd drop L3 was 0.6mm-0.9mm, thereby obtained the 3rd slope K 3 of corresponding base portion.As seen, the size of the 3rd slope K 3 of above-mentioned resulting base portion is that height with pedestal 7 is inversely proportional to.
In Figure 13,7 the 4th slope K 4 on that face of radiating fin 9 of pedestal have been reflected, because the 4th slope K 4 is identical with the 3rd slope K 3 of aforesaid base portion, so, determine as long as treat the 3rd slope K 3 of radiating fin 9 base portions, determine just have so with the 4th slope K 4 of the 3rd slope K 3 relation of following in sb's footsteps.
In Figure 14, illustrated that pedestal 7 has bigger height, in this case, just can remain with the 4th work zone 8 at 7 base portions towards radiating fin 9 of pedestal, pedestal 7 is thick more, and the 4th work zone 8 is just longer, to increase frictional resistance, use the material of waiting for the upper end and extrude together.As if technical scheme scope that though this kind situation is free on the inventive method to some extent to be limited, promptly on radiating fin 9, there is no first, second, third work zone 6,4,5, and remain with the 4th work zone 8 on the pedestal 7, belong to the mixed form that the inventive method combines with prior art, but it has used for reference method of the present invention fairly obviously.And for the structure shown in this figure, though still need to be aided with thick, the thin discharge processing of electric spark again after the online cutting when processing mold, process time can be short nearly one times than prior art.Because on radiating fin 9, do not have first, second, third work zone 6,4,5, do not need spark machined.In a word, Figure 14 is a kind of special case, only just selects with hybrid when pedestal 7 has higher height.
Embodiment
Way at first routinely is according to shape shown in the computer radiator product drawing that the user provided and in conjunction with the relevant size that is marked on the drawing, these sizes comprise that mainly the different thickness of top, middle part and bottom of the height of radiator fins and radiator fins and the quantity of the radiator fins in the unit are are that density also has relevant specification requirement etc., judge the distributed areas of aluminium stream 2 in view of the above and determine the die sinking pattern.For example by shown in Figure 15, different aluminium stream flow according to the upper, middle and lower portion of radiator fins, calculate first slope K 1 and second slope K 2 of both sides and the 3rd slope K 3 of base portion respectively, also have the 4th slope K 4 on the pedestal 7 identical with the 3rd slope K 3 in order to the end that is reflected to the radiating fin 9 that shaping mould gets on.Size and aluminium stream 2 according to slope export the principle that width are inversely proportional to, also promptly according to first, second, the 3rd, the 4th slope K 1, K2, K3, the principle that the size of K4 and aluminium stream 2 outlet width are inversely proportional to, in case being determined, the height of pedestal 7 and the thickness T of shaping mould (usually the height of pedestal 7 is got 3-12mm, thickness T is got 30-50mm), need only height and described first so according to the mentioned pedestal 7 in front, the 3rd drop L1, value relation between the L3 and the value relation between radiating fin 9 width (providing) and the second drop L2 by the user, just can be reflected to the end of the radiating fin 9 on the shaping mould particularly, both sides, first of base portion, second, the 3rd slope K 1, K2, K3 also has the 4th slope K 4 on the pedestal 7 identical with the 3rd slope K 3.As soon as the pattern of die sinking is definite, just directly shaped hole between the radiating fin 92 and the hole wall of escaping hole 3 are processed into the inclined-plane of inclination by the line cutting, make shaped hole 2 and escape hole 3 to constitute horn-like; Simultaneously, on corresponding inclined plane that end, both sides, the base portion of radiating fin 9 processes first, second, third different slope K 1 of each tool, K2, K3 and process four slope K 4 identical with the 3rd slope K 3 of the base portion of radiating fin 9 on pedestal 7.Can become more clear by the contrast of Figure 16 and Figure 17 for the advantage that obtains by present embodiment in order to the aluminium extracting mold that extrudes high density, high multiple computer radiator.
Figure 16 is the resulting radiating fin 9 of the processing method in the prior art, obvious have in order to control the work zone that aluminium flows 1 discharging speed, that is to say that it is the discharging speed that brings balance aluminium stream 1 by work, shaped hole 2 and escape to form each other between the hole 3 stair-stepping hole shape, so not only can make the intensity of radiating fin 9 show as fragility, and electric spark also must prolong thick, thin discharge time.Figure 17 is by the resulting radiating fin 9 of processing method of the present invention, obvious its no longer has the work zone, that is to say that it is the discharging speed that comes balance aluminium stream 1 by the variation of first, second, third, fourth slope K 1, K2, K3, K4, shaped hole 2 and escape hole 3 and show as tubaeform on the whole, the intensity of radiating fin 9 is protected, and directly by the line cutting processing, not need with and electric spark slightly, carefully discharge can shorten process time, processing cost can save.
