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 ...
