Embodiment Construction

[0020] see Figure 1~2 , the present invention relates to a mold with multiple aluminum alloy pipe hot extrusion dies, which are assembled and combined by an upper mold 1 and a lower mold 2 using pins 3 and screws 4 .

[0021] see image 3 ~5, the feed end of the upper mold 1 is provided with a decompression sink hole 1.1 that sinks 10mm. The distribution holes 1.2 of the upper mold 1 are distributed in multiples of the cavity 2.2 of the lower mold 2 and arranged around the cavity 2.2 of the lower mold 2 . All the bridge positions 1.3 of the upper mold 1 are processed into a drop-shaped structure, as shown in FIG. 5 . The discharge surface of the upper mold 1 is provided with a plurality of square head mold cores 1.5, and support bosses 1.4 are arranged between the square head mold cores 1.5. The square head mold core 1.5 of the upper mold 1 and the bridge position 1.3 transition smoothly.

[0022] Referring to Figures 6-7, the feed end of the lower die 2 is provided with ...

Abstract

The invention relates to a hot extrusion die of aluminum alloy pipes with multiple output, in particular to the hot extrusion of the aluminum alloy pipes and is formed by assembling and combining an upper die (1) and a lower die (2), wherein, a feeding end of the lower die (2) is provided with a welding chamber (2.1) and a die cavity (2.2) and a discharging hole (2.3) is processed at a discharging end of the lower die (2); the feeding end of the upper die (1) is provided with a decompress counter bore (1.1), and split flow holes (1.2) of the upper die (1) are distributed in a multiplied way with the die cavity (2.2) of the lower die (2) and are positioned at the circumference of the die cavity (2.2) of the lower die (2); all bridge sites (1.3) of the upper die (1) are processed into water drop structure; the discharging surface of the upper die (1) is provided with a plurality of square head die cores (1.5) which are provided with a support lug boss (1.4) among the square head die cores (1.5), and the lug boss (1.4) is closely and directly attached to the bottom part of the welding chamber (2.1) of the lower die (2); the square head die cores (1.5) and the bridge sites (1.3) are transited smoothly. The hot extrusion die can cause the extrusion products of the aluminum alloy pipes to be uniform in wall thickness, consistent in flow rate and high in rate of finished products.

Description

(1) Technical field [0001] The invention relates to an aluminum profile hot extrusion die. Hot extrusion of main aluminum alloy pipes. It belongs to the technical field of mold processing. (2) Background technology [0002] With the rapid development of the world economy, the demand for various resources is increasing, but many important resources are limited and non-renewable. How to save energy and reduce consumption has become our most important issue at present. Since the development of aluminum alloy as a product material, its unique advantages have been recognized by the world, and its application has become more and more extensive, and it has now involved all walks of life. Among them, aluminum alloy pipes are the most used variety of aluminum products. In order to improve production efficiency and reduce production costs, aluminum profile manufacturers are developing in the direction of more than one mold. However, at present, the uneven wall thickness of the prod...
