[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] The utility model provides Figure 1-5 The hot extrusion die for square tube aluminum profiles with grooves shown in the figure includes a die body 1, a hole 2 is opened on one side of the die body 1, and a diverter bridge 3 is arranged inside the hole 2. The diverter bridge 3 is composed of a central body 31 located in the middle and a plurality of support bodies 32 distributed around the outside of the central body 31. The hole 2 is divided into a plurality of diverter holes 5 by the central body 31 and the support bodies 32. The central body 31 is connected to a foreman 4 at the discharge port of the hole 2.

[0029] There are six diverter holes 5, and the two diverter holes 5 located at the top are provided with milling surfaces 51 at the corners close to the central body 31, for guiding the aluminum flow to impact the top surface of the foreman 4;

[0030] The inner wall of the two diversion holes 5 located in the middle close to the central body 31 is composed of a first inclined surface 52 located on the inner side and a second inclined surface 53 located on the outer side. The first inclined surface 52 and the second inclined surface 53 are both inclined from the outside to the inside away from the center direction of the central body 31, and are used to guide the aluminum flow to impact the left and right side surfaces of the foreman 4.

[0031] In one embodiment, the foreman 4 is in the shape of a rectangular parallelepiped as a whole, and two grooves symmetrically distributed about the center of the foreman 4 are provided on the top to control the forming shape of the square tube-type aluminum profile. The bottom surface of the foreman 4 is flush with the top of the discharge surface of the two diversion holes 5 located below, ensuring that the aluminum flow at the bottom of the foreman 4 is sufficient.

[0032] In one embodiment, the diverter hole 5 is made by a heat treatment process to improve the wear resistance of the diverter hole 5, making it relatively stable during use and having a long service life. The central body 31 and the support body 32 are integrally formed to facilitate the production and processing of the mold body 1.

[0033] In one embodiment, the angle between the first inclined surface 52 and the central body 31 is smaller than the angle between the second inclined surface 53 and the central body 31, so that the aluminum flow at the second inclined surface 53 can be guided to the first inclined surface 52, and the flow space becomes larger, ensuring the stability of the aluminum flow rate.

[0034] In one embodiment, the mold body 1 is made of H13 mold steel to ensure the strength of the mold body 1 . The mold body 1 is made of a cylindrical structure to facilitate the use of the mold body 1 .

[0035] The specific implementation method is as follows: when the utility model is used, the mold body 1 and the corresponding lower mold are assembled. After assembly, a gap is formed between the foreman 4 and the working belt of the lower mold, that is, a cavity. When aluminum flows through the mold body 1 and into the cavity, the aluminum flow is cooled and formed into a square tube-like aluminum profile with a groove, and is discharged through the discharge hole of the lower mold, thereby completing the production;

[0036] Specifically, the aluminum flow is first blocked by the diverter bridge 3, and then dispersed through the six diverter holes 5, and then divided into six branches that flow into the interior of the mold body 1, thereby reducing the impact force of the aluminum flow on the mold body 1, making the mold body 1 durable. Moreover, when the aluminum flow flows from the feed surface of the diverter holes 5 to the discharge surface, the two milling surfaces 51 are provided, so that the two upper aluminum flows can converge toward the central body 31 when flowing. When the two aluminum flows flow out through the discharge surface of the diverter holes 5, they can directly impact the top surface of the foreman 4, ensuring that the aluminum flow above the foreman 4 is adequately supplied and evenly dispersed.

[0037] At the same time, by providing two second inclined surfaces 53, the feed surface areas of the two middle diverter holes 5 are suddenly increased, which can increase the aluminum flow storage capacity in the two middle diverter holes 5. At the same time, the second inclined surface 53 guides the aluminum flow to flow stably toward the first inclined surface 52, so that the two aluminum flows inside the two middle diverter holes 5 can impact the left and right surfaces of the foreman 4 when flowing out through the discharge surface of the diverter hole 5, ensuring sufficient material supply on the left and right sides of the foreman 4. The bottom surface of the foreman 4 is flush with the top of the discharge surface of the two diverter holes 5 located below, which can ensure sufficient aluminum flow at the bottom of the foreman 4.

[0038] In summary, when the square tube aluminum profile with grooves is produced through the mold body 1, the four sides of the foreman 4 are not blocked by the diverter bridge 3, and the aluminum flow flowing through the four sides is sufficient. The foreman 4 can be directly hit by the aluminum flow from the diverter hole 5 in the aluminum flow, and the aluminum flow rate on each side is relatively balanced, following the rule that the angle is faster than the surface. This not only reduces the extrusion force required for the aluminum flow to be formed, but also speeds up the speed at which the aluminum flow is formed into the square tube aluminum profile with grooves in the mold cavity, thereby improving production efficiency and ensuring the production quality of the square tube aluminum profile with grooves.

[0039] This embodiment specifically solves the problem in the prior art that when the current mold body 1 produces square tube aluminum profiles with grooves, the side wall of the foreman 4 is blocked by the diversion bridge 3, resulting in insufficient aluminum flow supply at various locations on the outer wall of the foreman 4 and unbalanced flow, which affects the quality of the finished product of the square tube aluminum profiles with grooves.

[0040] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
