Embodiment Construction

[0021] Referring to FIGS. 1-2 , the hot extrusion die for a large cantilever type false split aluminum profile according to the present invention is composed of a deflector 1 , a die face 2 and a die pad 3 . Two screws 6 and two pins 5 are used to connect the deflector 1 and the mold surface 2, and the outer circumference is tightly matched with a seam.

[0022] Referring to Figures 3 to 4, the feed surface of the deflector 1 is evenly distributed with several splitter holes 1.1 (there are four in the figure), the discharge surface of the deflector 1 is provided with sinking bridges 1.2, and the deflector 1 A dummy mold core 1.3 is provided at the center of the discharge surface of the dummy mold core 1.3, and a screw hole 1.4 is provided at the center of the dummy mold core 1.3, which is used to fix the large cantilever at the center of the mold surface.

[0023] Referring to Figures 5-6, the center of the die surface 2 is provided with a large cantilever 2.3, the feed surfac...

Abstract

The invention relates to a pseudo-flow dividing aluminum profile hot extrusion mould which belongs to the large cantilever class and is used for the hot extrusion of aluminum products with higher request to the profile surface of the large cantilever. The mould comprises a guide plate (1), a mold surface (2) and a mold pad (3), the feeding surface of the diversion plate (1) is uniformly distributed with flow-dividing holes (1.1), a discharge surface is provided with a bridge down position (1.2), the middle of the discharge surface is provided with a pseudo mold core (1.3), the middle of which is provided with a screw hole (1.4), the middle of the mold surface (2) is provided with the large cantilever (2.3), the peripheral feeding surface of the mold surface of the large cantilever (2.3) is provided with a mold cavity (2.1), the discharge surface is provided with a discharge hole (2.2), the middle of the large cantilever (2.3) is provided with a lock screw hole (2.4), the middle of the large cantilever (2.3) of the mold surface (2) is locked on the pseudo mold core (1.3) of the guide plate by lock screw (4), the middle of the mold pad (3) is provided with a discharge hole (3.1), the shape of which is matched with that of the discharge hole (2.2) of the mold surface (2), and the discharge hole (3.1) of the mold pad (3) is larger than the discharge hole (2.2) of the mold surface (2). The mold can produce the aluminum profile in the large cantilever class, with good surface quality, low production cost and long service life in the large cantilever class.

Description

(1) Technical field [0001] The invention relates to an aluminum profile hot extrusion die. It is mainly used for hot extrusion of aluminum products with large cantilever and high profile surface requirements. It belongs to the technical field of mold processing. (2) Background technology [0002] Due to the rapid development of aluminum product processing technology, customers have higher and higher requirements for products, and the products are also diversified, complicated and specialized. There are countless industries involved in aluminum products. Among them, there are more and more large cantilever aluminum profiles (Figure 9), and a large part of them have higher requirements on the surface. Traditional design schemes (such as: joint design, tear opening design) cannot meet the development requirements of this type of material. It will be difficult to achieve the predetermined output if the flat mold is directly made, resulting in high production costs. And the ...
