Embodiment Construction

[0032] The specific embodiments and examples of the present invention will be described in detail below in conjunction with the accompanying drawings. The described specific embodiments are only used to explain the present invention, and are not intended to limit the specific embodiments of the present invention.

[0033] still with figure 1 Take the most widely used radiator aluminum profile product in the market as an example. For the production of this hot-extruded aluminum profile product, the traditional radiator aluminum profile extrusion die has a mold structure The overall design is not reasonable enough, mainly reflected in the following three aspects:

[0034] 1. The design of the split hole of the upper die is unreasonable. At present, the enterprises adopt the "X" shape split bridge layout, and all adopt the conventional four split hole design, which leads to the metal in the center of the four cavities intersecting in the extrusion process. It is difficult to ach...

Abstract

The invention discloses a radiator extrusion die. Transverse radiating fins located at the lowermost ends of the outer sides of two closed cavities in the upper portion serve as the transverse center line of the whole die; a middle shunting hole is partially overlapped with the four closed cavities; the left and right shunting holes cover the heads of the arc-shaped radiating fins and the roots of the outermost longitudinal radiating fins, and the inner boundaries of the left and right shunting holes coincide with the top ends of the transverse radiating fins; tan upper-end shunting hole region covers the longitudinal radiating fins in the middle of an aluminum profile, and a lower-end shunting hole region is separated from the two closed cavities in the lower part; due to the fact that the center of the die is moderately deviated from the center of a heating radiator profile, and the distribution scheme of five flow guide holes is combined, extrusion forming is easy, and the size precision and the surface quality of a radiator aluminum profile product are improved; and the die is reasonable in structural design, the wall thickness of the product is uniform, metal supply and flowing between cores are effectively improved, and the defect that a heating radiator type radiator aluminum profile is prone to cracking and water leakage in the using process is overcome.

Description

technical field [0001] The invention relates to the field of hot extrusion dies for producing radiator aluminum profiles, in particular to an extrusion die for producing radiator aluminum profiles. Background technique [0002] With the improvement of people's living standards, in the cold winter, the indoor heating equipment in northern China has been gradually replaced by the current aluminum alloy material from the cast iron material in the past. The heating equipment made of aluminum alloy material not only has better heating effect and is more environmentally friendly. , and the structure of the heating equipment is also more compact, light and beautiful. [0003] At present, the aluminum alloy materials used in indoor heating equipment are all hot-extruded aluminum profiles, because aluminum profiles are suitable for mass production and are easier to meet market demand. At the same time, manufacturing and installation are simpler. Therefore, radiators made of aluminum ...
