The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1 to 8, the extrusion die for the high power tooth heat sink comprises a material guide plate 1, an upper die 2 and a pad 3 which are sequentially connected from top to bottom, wherein the material guide plate 1, the upper die 2 and the pad 3 are all connected through bolts.

The material guide plate 1 is internally provided with a material inlet 4 for guiding the work material to enter the die hole of the upper die 2, and meanwhile, the material guide plate also plays a role in protecting the upper die 2. The upper end of a feed inlet 4 of the material guide plate 1 is I-shaped, the lower end of the feed inlet 4 is rectangular, and two inclined planes 10 are formed inside the feed inlet 4, so that the I-shaped port is transited to the rectangular port, and the work material can sufficiently and uniformly enter the die holes 5. The I-shaped opening shields the strip-shaped hole 9 from above, in order to prevent the flow rate of the work material at the heat sink base plate 12 from being too high.

Be equipped with through-hole 7 in the pad 3, feed inlet 4, nib 5 and through-hole 7 communicate with each other, and nib 5 is including communicating trapezoidal hole and bar hole 9, and trapezoidal downthehole fixed with a plurality of grid plate 8 that forms radiator fin 11, forms radiator base plate 12 in the bar hole 9. The strip hole 9 is internal to go up mould 2 and fill up 3 one side in opposite directions and form cubic dead sword 6, has guaranteed that the aluminium alloy passes through, has strengthened the life-span of mould. The grating plates 8 are distributed along the trapezoidal holes and are in an inclined dispersion shape.

The working materials firstly enter the feeding hole 4, and the expansion is formed inside the feeding hole 4, so that the sufficient working materials can be stored inside the guide plate 1. Because the flow velocity at the fins is slow, the position of the base plate of the radiator is shielded at the feeding position of the material guide plate 1 so as to reduce the flow velocity at the base plate, and meanwhile, the root of the fins is completely shielded by the material guide plate 1, so that the cantilever (namely, the radiator fins at two sides) cannot be deviated. The work material has a predeformation process at the beginning of extrusion, prevents to produce great pressure in the extrusion process, has played the effect of protection mould. The opposite side of the upper die 2 and the material guide plate 1 is provided with a die hole 5, in order to reduce the proportion coefficient of the height of the fin and the gap between adjacent fins, the fins of the die hole type are designed to be inclined and dispersed, and the position of the base plate is not changed, so that the strength of the die can be increased, and the unqualified product caused by the offset of the fins is prevented. One side of going up mould 2 and pad 3 in opposite directions is formed with the cubic dead knife of radiator base plate 12, makes the aluminium alloy can be safe through going up mould 2, does not take place the effort with the mould, has played the effect that strengthens the mould life-span. The upper die 2 is connected with the material guide plate 1 and the pad 3 through bolts to form a set of complete extrusion die of the high-power tooth radiator.

The extrusion process of the high-power tooth radiator adopts the extrusion die of the high-power tooth radiator, and comprises the following steps:

a, performing surface treatment on a cast rod, and removing a cast hard shell and a surface oxide layer by using a peeler so as to avoid influencing the quality of a section;

step B, preheating the processed aluminum alloy cast rod, wherein the preheating mode is step heating, the head of the cast rod is heated to 480-500 ℃, the middle part of the cast rod is heated to 460-480 ℃, the tail part of the cast rod is heated to 440-460 ℃, in order to prevent the cast rod from being adhered to a die, carbon powder is sprayed on the cast rod, and the cast rod is placed into an extrusion cylinder of an extruder;

step C, uniformly heating the die by a far infrared heating furnace, wherein the heating temperature of the die is 470-490 ℃;

step D, an extrusion device of the extrusion cylinder pushes the aluminum alloy cast rod to a high-power tooth radiator mould at an extrusion speed of 1.8-2.5m/min, and the aluminum alloy cast rod is extruded and formed into an extruded part from the mould;

e, cutting off the head and the tail which have mechanical properties which do not meet the requirements and are deformed;

step F, slightly air-cooling the radiator base plate 12 on line by using the extruded section, wherein the cooling mode of the fins is natural cooling, so that the fins are prevented from deforming to cause the product to be unqualified;

step G, straightening the cooled section, fixing the section on a stretching straightening machine for straightening, and then cutting the section to length to obtain the length meeting the requirement;

and step H, finally, carrying out aging treatment to ensure that the mechanical property meets the requirement. The ageing temperature is 180 ℃, and the ageing time is 7 hours. The finished profile is obtained, as shown in fig. 9.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
