Problems solved by technology

[0002] At present, the die-casting of radiators is mainly produced by conventional liquid die-casting, and because the heat energy stored in the liquid die-casting slurry is too large, it is easy to cause cracks in the mold, and the radiators produced by it cannot be directly solidified. heat treatment

Embodiment Construction

[0026] In order to fully understand the technical content of the present invention, the technical solution of the present invention will be further introduced and illustrated below in conjunction with schematic diagrams, but is not limited thereto.

[0027] Such as figure 1 As shown, a semi-solid die-casting forming method of a broken-tooth radiator includes the following steps:

[0028] A. Prepare a semi-solid slurry or blank; in step A, the solid rate of the slurry or blank is 20%-80%, the silicon content of the slurry or blank is in the range of 1%-10%, the thermal conductivity of the alloy is high, and the product Good heat dissipation;

[0029] B. Die-casting forming broken-tooth radiator; In step B, a special die-casting mold is used to form the radiator. When die-casting, the gate of the mold is located at the geometric center of the broken-tooth radiator, which shortens the semi-solid slurry injection distance and reduces the filling flow. fluctuations, the speed ran...

Abstract

The invention discloses a semisolid die casting forming method for a broken tooth radiator. The semisolid die casting forming method comprises the following steps that A, semisolid slurry or a semisolid blank is prepared; B, the broken tooth radiator is formed through die casting; and C, heat treatment is conducted, and in the step A, the solid rate of the slurry or the blank ranges from 20% to 80%. By means of the semisolid die casting forming method, the service life of the die is prolonged, solid solution heat treatment can be conducted, meanwhile, semisolid slurry layer is in laminar filling, sequential solidification is formed, an inner dense solidification structure in the radiator is guaranteed, and the requirement of communication products for the radiator can be met.

Description

technical field [0001] The invention relates to the field of die-casting, in particular to a semi-solid die-casting method for radiators. Background technique [0002] At present, the die-casting of radiators is mainly produced by conventional liquid die-casting, and because the heat energy stored in the liquid die-casting slurry is too large, it is easy to cause cracks in the mold, and the radiators produced by it cannot be directly solidified. heat treatment. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a semi-solid die-casting forming method for a tooth-broken radiator. [0004] Technical scheme of the present invention is: [0005] A semi-solid die-casting method for a broken-tooth radiator, comprising the following steps: A. preparing a semi-solid slurry or blank; B. die-casting a broken-tooth radiator; C. heat treatment; wherein, in the step A, the The s...
