Problems solved by technology

[0003] As far as we know, most of the extrusion cylinders used in aluminum profile factories are round because they cannot solve the strength problem of flat extrusion cylinders well, while the cross-sections of gear-shaped profiles are flat and elongated, which is the first The secondary pre-deformation caused a lot of difficulties, and the pressure on the mold was also greater

Embodiment Construction

[0027] see figure 1 , 2 , The hot extrusion die for the aluminum profile of the spline fin radiator of the present invention is formed by superimposing the front deflector 1, the deflector 2, the die surface 3 and the die pad 4 sequentially from front to back. The front deflector 1 is connected with the deflector 2 with screws 5 and pins 9, the deflector 2 is connected with the mold surface 3 with screws 7 and pins 8, and the mold surface 3 is connected with the mold pad 4 with pins 6,

[0028] see image 3 , 4, 5, the front deflector 1, the center of the diversion opening 11 is a conical diversion opening 111, and the two sides are oblique push type expansion diversion openings 112.

[0029] see Image 6 , 7 , the deflector 2, the feed end of the diversion port 21 is an expanded diversion port 211, and the discharge end is a direct guide diversion port 212.

[0030] see Figure 8 , 9 , the shape of the diversion pit 31 at the feed end of the die surface 3 is consisten...

Abstract

The present invention relates to hot extruding mold for aluminum profile of fin inserting heat radiator. The hot extruding mold consists of front guide plate, guide plate and mold face. The front guide plate has two inclined expanding guide ports, the guide plate has expanding guide port in the material feeding end and straight guide port in the discharge end, and the mold face has guide notch in the same shape as the straight guide port in the discharge end of the guide plate. The present invention can perform three pre-deformations of different properties to facilitate the production of aluminum profile of fin inserting heat radiator.

Description

Technical field: [0001] The invention relates to a hot extruding die, in particular to a hot extruding die for an aluminum profile of a gear fin radiator. It belongs to the technical field of radiator moulds. Background technique: [0002] As we all know, radiator type hot extrusion mold is a major difficulty in the mold industry. In particular, factors such as excessive wall thickness disparity, excessive tongue ratio, excessive circumscribed circle, and complex shape lead to problems such as difficult mold forming, instability, and low output, which makes the scrap rate of radiator hot extrusion molds much higher than that of ordinary molds. mold. And the profile of the gear fin radiator (see Figure 12 ) tends to be four major problems of large disparity in wall thickness, dense teeth, long and flat shape, and exceeding the range of aluminum rods. To improve the production efficiency of this aluminum profile, it is not necessary to solve these four major problems from ...
