Description
Technical field
The utility model relates to and a kind of large-scalely spreads fin the Aluminum-Extruding Die.
Background technology
Aluminum products have a series of good characteristic, as features such as intensity are good, against weather is good, density is little, are often used to make heat sink part or external ornament.At present, in the production process of aluminium section bar, need to use extrusion die to carry out plastotype to aluminium section bar, in use, the stock mould heat of extrusion die distributes slowly, and radiating effect is poor, and long-time use easily causes burn failure.In actual production, extrusion die directly completes metal plastic deformation, for the heat radiator aluminium profile extrusion die that production tooth depth is long or complex-shaped, the tooth depth of the radiator produced due to mould is long, the speed that temperature outside die working length profile of tooth nib is distributed, the speed that temperature inside it is distributed is slower, make each working region heat radiation of die working length profile of tooth nib uneven, and cause product to occur pendulum tooth, distortion or fracture, have a strong impact on product quality, cause product yields on the low side, and the scrappage of extrusion die is also far away higher than the common die of other types.
Utility model content
The utility model object is: provide a kind of and large-scalely spread fin the Aluminum-Extruding Die, to improve product yields, reduce scrappage, and heat radiation evenly.
The technical solution of the utility model is: one is large-scale spreads fin the Aluminum-Extruding Die, it comprises: patrix, middle mould, counterdie, be arranged on patrix and middle mould or the fixture between middle mould and counterdie, entering on charge level of wherein said patrix is distributed with a upper pod apertures, pod apertures during middle mould is provided with and is connected with upper pod apertures, described counterdie is provided with the work strip be connected with middle pod apertures, and described work strip is provided with multiple tooth position nib and of being all connected with tooth position nib assembles position nib.
On the basis of technique scheme, comprise following attached technical scheme further:
Described upper pod apertures is identical to the direction sectional area of middle mould along patrix, and the sectional area of middle pod apertures becomes large gradually along the direction of charging.
The feed end of described counterdie is designed to plane, and discharge end is then provided with the discharging opening be connected with work strip.
The width of described tooth position nib is 0.5mm, and the spacing of adjacent two tooth position nibs is 2mm.
Material is H13 mould steel, and extruded product is fin.
Described assembling position nib has two different width at least.
The utility model advantage is:
The utility model improves product yields, reduces scrappage, and heat radiation evenly, can improve machining accuracy and efficiency, reduce costs.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is sectional view of the present utility model;
Fig. 2 is the schematic diagram of pod apertures and work strip in the utility model.
Detailed description of the invention
Embodiment: as shown in Figure 1-2, the utility model provides a kind of large-scale specific embodiment spreading fin the Aluminum-Extruding Die, it comprises: patrix 10, middle mould 20, counterdie 30, be arranged on patrix 10 and middle mould 20, or the fixture 40 between middle mould 20 and counterdie 30, entering on charge level of wherein said patrix 10 is distributed with a upper pod apertures 12, and this pod apertures 12 is identical to the direction sectional area of middle mould 20 along patrix 10, middle mould 20 is provided with middle pod apertures 22, and sectional area becomes large gradually along the direction of charging, described counterdie 30 is provided with the work strip 32 be connected with middle pod apertures 22, described work strip 32 is provided with multiple tooth positions nib, with one that to be all connected with tooth position nib is assembled position nib 34.Multiple tooth positions nib is parallel interval spread configuration, the width 0.5mm of tooth position nib, the spacing 2mm of adjacent two tooth position nibs, and assembling position nib 34 has two different width at least, make with the distance of the opinion of tooth position nib near or away from.Mold materials selects H13 mould steel, thus by product that this mould is extruded, be applied to computer CPU, video card fin, power supply heat sinking sheet, communications industry fin, LED lamp etc., it goes out material vane thickness 0.5mm, blade pitgh is 2mm, blade amt reaches 36, every sheet all claims gap to be less than 0.02mm, blade height overall reaches 47.5mm, each blade height all claims gap to be less than 0.03mm, extrusion profile blade number is many, thin, all title degree gap is little, section is complicated, the utility model gets long distribution in conjunction with patrix pod apertures appropriate design and die face work strip, dividing with wall thickness thicker drives gear piece and hollow core portion to make overall discharging speed even, reduce front and back squeeze pressure gap, effectively control easy broken teeth in production process, the phenomenons such as pendulum tooth, reach balanced aluminium charging, effectively protect less tooth position, greatly increase the mold use life-span.
Certain above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the Spirit Essence of the utility model main technical schemes or modification, all should be encompassed within protection domain of the present utility model.
