[0003] The utility model with the publication number CN215543802U discloses an aluminum profile extrusion mold, which relates to the technical field of aluminum material forming, to solve the problems that the uneven stress on both sides of the existing aluminum profile easily leads to the phenomenon of unevenness at both ends of the aluminum profile and it is extremely inconvenient to demold and transfer the formed aluminum profile after extrusion, consuming a lot of time, and the profile body is easily damaged by hoisting. An aluminum profile extrusion mold includes a limiting frame; the limiting frame is in a U shape as a whole, and there are four supporting feet at the bottom of the limiting frame, and the upper position at the rear end of the limiting frame is fixedly connected to the front end position of the first limiting frame. Since a clamping template is arranged at the right side position of the first clamping plate and a clamping template is arranged at the left side position of the second clamping plate, and they are symmetrically arranged, when the appearance of the extruded aluminum profile needs to be fixed, the corresponding clamping template can be replaced according to the appearance to be extruded, ensuring the forming effect of the aluminum profile and achieving convenient replacement and time reduction.

[0004] Since a sawtooth groove for forming a fin radiator is arranged in the mold structure in the extrusion mold, and when extruding aluminum materials, the raw materials need to be softened and then extruded into the mold, and the required fin radiator is formed according to the shape of the mold. Since the softened aluminum material needs to extend out after entering the mold, at this time, the temperature of the mold is relatively high, and the hardness of the formed aluminum profile mold is not high, and it is easy to generate deformation.

[0032] The utility model is described in detail below with reference to the accompanying drawings.

[0033] like Figure 1-4 As shown, a processing mold for forming an aluminum profile thin fin heat sink includes a fixing seat 1, the fixing seat 1 is formed with a guide hole 21, the guide hole 21 is installed with a mold tube 11, the mold tube 11 is installed with a fin core 12 for forming the fin heat sink, the mold tube 11 is divided into a forming area 13 and a cooling area 14, the lengths of the forming area 13 and the cooling area 14 are respectively the same, the cooling area 14 is formed with a water-cooling cavity 15 located on the wall of the mold tube 11 and a water-cooling inlet 16 and a water-cooling outlet 17 connected to the water-cooling cavity 15; the forming area 13 is installed with a connecting plate 18, and the connecting plate 18 is annular and equidistantly penetrated with a plurality of connecting holes 19.

[0034] During extrusion molding, the softened raw material is squeezed into the mold barrel 11, passes through the molding area 13, and is formed into the desired shape through the fin mold core 12. Then the formed aluminum material continues to pass through the cooling area 14. Since the side wall of the cooling area 14 is formed with a cooling cavity, water cooling liquid can be introduced through the water cooling inlet 16 and the water cooling outlet 17, so that the temperature of the molding area 13 is relatively low, which is convenient for cooling the aluminum radiator after molding, reducing the probability of deformation caused by softening, and improving the molding quality.

[0035] A portion of the molding area 13 of the mold tube 11 is inserted into the guide hole 21 of the fixed seat 1, and the mold tube 11 is positioned through the guide hole 21 of the fixed seat 1. The mold tube 11 is coaxially positioned in the guide hole 21 of the fixed seat 1; guide plates 2 are respectively installed on both sides of the fixed seat 1, and the guide plates 2 are formed with through grooves 22 coaxially aligned with the guide holes 21. The fixed seat 1 is further protected by the guide plates 2, and the mold tube 11 passes through the through grooves 22 and the guide holes 21 and is thus installed in the fixed seat 1.

[0036] A driving cavity 23 is formed in the fixed seat 1, and the driving cavity 23 is provided with a driving member 3 for driving the mold tube 11 to rotate. Bearing seats 24 that rotate with the mold tube 11 are respectively installed at both ends of the guide hole 21; driven by the driving member 3, the mold tube 11 will cooperate with the bearing seat 24 and rotate in the guide hole 21, so that the forming direction of the aluminum profile radiator changes.

[0040] Furthermore, telescopic cylinders 35 are respectively installed on the two side walls of the fixed seat 1, and the driving ends of the telescopic cylinders 35 are respectively connected to the driving shafts 34. The telescopic cylinders 35 can drive the driving shaft 34 to move axially along the driving hole 33, so that the driving rack 32 formed on the driving shaft 34 can mesh with the driving gear 31 for transmission, thereby driving the mold cylinder 11 to rotate.

[0041] Preferably, the driving hole 33 is installed with a guide sleeve 36, which guides the driving shaft 34 for sliding. The guide sleeve 36 is also formed with a plurality of side wall holes 37, and the cylinder body of the telescopic cylinder 35 is connected to the side wall holes 37 of the guide sleeve 36; thereby, the telescopic cylinder 35 is installed on the fixed seat 1.
