Description

Technical Field

[0001] This utility model specifically relates to an aluminum profile extrusion molding die. Background Technology

[0002] Aluminum profile extrusion molding dies are specialized process dies used for extruding aluminum alloy profiles. They are widely used in the processing and production of aluminum profiles in industries such as construction, transportation, machinery, and electronics.

[0003] Existing aluminum profile molds are relatively simple. During extrusion, the aluminum material flow is not smooth, resulting in material shortage or over-feeding, which leads to unstable wall thickness of the formed aluminum profile and affects product quality. In addition, after extrusion, it is not convenient to quickly separate the mold for mold maintenance, such as lubrication or nitriding treatment. Therefore, we propose an aluminum profile extrusion molding mold. Utility Model Content

[0004] The purpose of this utility model is to provide an aluminum profile extrusion molding die to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum profile extrusion die, comprising:

[0006] A first mold, wherein a flow diversion hole is provided through the inner side of the first mold;

[0007] The mold core is fixed to the inner wall of the diversion hole by a support block to shape the inner cavity of the product;

[0008] The second mold is disposed on one side of the first mold, and a guide assembly is provided between the second mold and the first mold;

[0009] The discharge hole is located inside the second mold, and one end of the discharge hole has an outwardly expanding beveled portion;

[0010] A cavity is formed at one end of the diversion hole, and the edge of the cavity corresponds to the edge of the beveled surface.

[0011] Preferably, the inner wall of the discharge hole is fixed with a protrusion that shapes the outer wall of the product, offset from the mold core.

[0012] Preferably, the inner diameter of the cavity is larger than the inner diameter of the diversion hole.

[0013] Preferably, the guide assembly includes a guide post and a top block. The guide post is fixed to one side wall of the first mold, and the side wall of the second mold has a positioning groove that cooperates with the guide post. The guide post has a guide groove that slides with the top block on its inner side, and the guide groove has a spring that pushes the top block to move on its inner side.

[0014] Preferably, the top block has a U-shaped cross-section and a chamfer at the lower end.

[0015] Preferably, the guide assembly is provided at least twice along the circumferential direction of the first mold.

[0016] Preferably, the second mold has the same outer diameter as the first mold.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] (1) This utility model, by setting multiple diversion holes, cavities and inclined surfaces, avoids the unstable flow of aluminum material during extrusion molding, which affects the defects of profile products. This device can effectively divide the aluminum material evenly and then temporarily store the plastic flow of aluminum material, thereby ensuring uniform distribution of extrusion pressure during extrusion. The flowing aluminum material can also easily flow into the inner side of the discharge hole for molding through the inclined surface, thus improving product quality.

[0019] (2) By setting guide pillars, springs and top blocks, the first mold and the second mold are not difficult to separate after the aluminum material is extruded. This device can separate the first mold and the second mold well by elastic force, which is convenient for mold separation, so as to facilitate the cleaning or nitriding treatment of the inner wall of the first mold and the second mold. It is easy to operate and easy to use. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 This utility model provides a technical solution: an aluminum profile extrusion molding die, comprising:

[0028] The first mold 1 has a flow diversion hole 5 through the inner side of the first mold 1;

[0029] This facilitates the even distribution of aluminum profiles, thereby improving the flow of aluminum materials during shaping;

[0030] The mold core 8 is fixed to the inner wall of the diversion hole 5 by a support block to shape the inner cavity of the product;

[0031] The second mold 2 is disposed on one side of the first mold 1, and a guide component 10 is provided between the second mold 2 and the first mold 1;

[0032] The mold core 8 extends into the inner side of the discharge hole 3, and the two work together to extrude and form a shape. Figure 5 The product shown;

[0033] The discharge hole 3 is located inside the second mold 2, and one end of the discharge hole 3 has an outwardly expanding inclined surface 4;

[0034] The inclined section 4 facilitates the flow of the extruded material into the discharge hole 3, ensuring uniform delivery of the aluminum material.

[0035] Cavity 7 is opened at one end of the diversion hole 5, and the edge of cavity 7 corresponds to the edge of the inclined surface 4;

[0036] Both the cavity 7 and the inclined surface 4 can temporarily store the extruded aluminum material, so that the aluminum flow into the discharge hole 3 flows more evenly and improves the uniform feeding effect.

[0037] In this embodiment, preferably, the inner wall of the discharge hole 3 is fixed with a protrusion 9 that shapes the outer wall of the product, which is offset from the mold core 8, so as to shape the outer wall of the aluminum profile during extrusion to form a groove.

[0038] In this embodiment, preferably, the inner diameter of the cavity 7 is larger than the inner diameter of the diversion hole 5;

[0039] This facilitates better temporary storage of the extruded aluminum flow, and then feeds it at a uniform speed into the discharge hole 3 after it is filled, so that the aluminum flow rate is stable during the extrusion molding process.

[0040] In this embodiment, preferably, the guide assembly 10 includes a guide post 101 and a top block 104. The guide post 101 is fixed to one side wall of the first mold 1, and one side wall of the second mold 2 has a positioning groove 6 that cooperates with the guide post 101. The guide post 101 has a guide groove 102 that is slidably connected to the top block 104 on its inner side, and the guide groove 102 has a spring 103 that pushes the top block 104 to move on its inner side.

[0041] The spring 103 is used to push the first mold 1 and the second mold 2 apart so as to separate the molds.

[0042] In this embodiment, preferably, the top block 104 has a "U" shaped cross-section and a chamfer 1041 at the lower end of the top block 104, which facilitates the top block 104 to enter the inner side of the positioning groove 6 for mold closing.

[0043] In this embodiment, preferably, the guide component 10 is provided at least two times along the circumference of the first mold 1 to facilitate better guiding effect.

[0044] In this embodiment, preferably, the second mold 2 has the same outer diameter as the first mold 1.

[0045] The working principle and usage process of this utility model are as follows: During use, the first mold 1 and the second mold 2 are engaged with the guide post 101 via the positioning groove 6 to close the mold. At this time, the ejector block 104 is pressed into the inner side of the guide groove 102, the spring 103 is compressed and shortened, and the aluminum material is squeezed by external equipment. Then, after being evenly distributed through the diversion hole 5, it flows into the space between the cavity 7 and the inclined surface 4 for temporary storage. After the aluminum material is further compressed, it flows into the inner side of the discharge hole 3 through the inclined surface 4, where the mold core 8 and the protrusion 9 shape the aluminum material to form... Figure 5 The aluminum profile product shown can be quickly separated from the first mold 1 and the second mold 2 by the elastic force of the spring 103 during the later mold separation process, so as to facilitate the replacement of another first mold 1 and second mold 2 for mold closing to process aluminum profiles.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
