Embodiment Construction
[0024] Below in conjunction with accompanying drawing, by processing the aluminum alloy computer CPU heat sink as an example, the present invention is further illustrated the manufacturing process of the high-precision large cantilever heat sink type parts.
[0025] Such as figure 1 As shown, it is the target processing product of the present invention—aluminum alloy computer CPU heat sink. The product structure features: the middle part is a circular ring, and many slender ribs are evenly distributed around it.
[0026] Such as Figure 11 As shown, the planar split-flow composite mold with a raised center, drooping surroundings, and an overall umbrella shape mainly includes an upper mold 1, a middle mold 2, and a combined lower mold composed of a working belt insert 3 and an empty knife 4. When combined, pins and (or) bolts can be used to form a detachable connection.
[0027] Such as figure 2 , 3 As shown, the upper mold 1 is provided with six vertical distribution hole...

A method for preparing a high-precision large-cantilever radiator section bar by the utilization of an umbrella-shaped die relates to the technical field of aluminium alloy product extrusion moulding technology. The method comprises the following steps of: carrying out homogenizing annealing treatment on an aluminium alloy casting blank, heating the blank, preheating a forming die, carrying out extrusion molding, cutting off a head portion and a tail portion, and carrying out solution treatment and artificial aging treatment. The forming die adopted during the extrusion molding process is an umbrella-shaped porthole die with an upheaving center and drooping periphery. By the adoption of the method for preparing the high-precision large-cantilever radiator type components by the utilization of the umbrella-shaped porthole die, metal can flow towards an area where it is hard for forming, and the metal has good fillability, uniform flow velocity and high production efficiency.
Description
technical field [0001] The invention relates to an extrusion forming process of an aluminum alloy product, in particular to the technical field of preparing a high-precision large cantilever cooling device by using an umbrella mold. Background technique [0002] Radiator type material is an indispensable part in machinery, electronics and other industries. Its main function is to dissipate heat, reduce the temperature of working parts, and increase the service life. At this stage, extrusion is generally used for production and preparation. Extrusion production has a series of advantages, such as high production efficiency, dense internal structure of materials, material saving, and good heat transfer effect. [0003] However, there are still certain difficulties in the extrusion of high-precision large cantilever parts. The main problem is that the distribution of metal is unreasonable during the forming process. short service life, etc. Therefore, there is no report on e...
