Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy mold technology, and more specifically to an aluminum profile mold with a hook. Background Technology

[0002] Aluminum profiles are widely used in the automotive industry due to their excellent performance, superior corrosion resistance and wear resistance, excellent electrical insulation and light weight. As automotive lightweighting has become a trend in automotive development, aluminum profiles will be used even more extensively in automobiles.

[0003] Aluminum profiles are alloy materials with aluminum as the main component. Aluminum rods are melted and extruded to obtain aluminum materials with different cross-sectional shapes. The production process of aluminum profiles requires multiple steps, including mold forming and subsequent processing.

[0004] In aluminum profile production, profiles with hooks often exhibit uneven flow rates during extrusion due to the difference in area and thickness between the solid and hook portions. This can lead to dimensional discrepancies between the profile dimensions and the drawings, impacting product quality. Traditional molds struggle to effectively address this uneven flow rate issue, necessitating the design of a mold that ensures uniform material flow across different sections. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide an aluminum profile mold with hooks, so as to solve the problems mentioned in the background art, such as uneven flow rate and non-compliance with size requirements caused by large differences in thickness of the profile.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0007] A hook-type aluminum profile mold includes a mold body, a backing plate on the mold body, and a solid working strip and a hook working strip for extruding the aluminum profile between the backing plate and the mold body. The solid working strip and the hook working strip are connected within the mold body. The fluid inlet end of the solid working strip is provided with a solid feeding cavity to prevent the flow rate of the solid part from being too fast during the extrusion process. The edge of the solid feeding cavity has a stepped structure. The feeding end of the hook working strip is provided with a hook feeding cavity to accelerate the fluid flow rate of the hook part.

[0008] To further optimize the technical solution, the edge of the feeding chamber of the hook part is a sloping structure.

[0009] To further optimize the technical solution, the inclination angle of the feeding chamber of the hook part is 10°.

[0010] The technical solution is further optimized so that the length of the solid feed chamber is 25mm and the length of the solid working belt is 22mm.

[0011] To further optimize the technical solution, bolts are provided between the mold body and the pad to fix the mold body and the pad.

[0012] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.

[0013] This utility model provides an aluminum profile mold with hooks. By specifically designing the structure of different parts of the mold, adding a pad to enhance the mold's rigidity, using a stepped feeding chamber and an extended working belt to slow down the flow rate in the solid part, and using a sloped and enlarged feeding chamber to accelerate the flow rate in the hook part, it effectively solves the problem of uneven flow rate caused by large differences in profile thickness. This ensures that the output flow rate of the solid part and the hook part is uniform, guarantees that the profile dimensions meet the drawing requirements, and improves the production quality of aluminum profiles. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the fluid inlet surface of this utility model.

[0015] The components are: 1. mold body, 2. pad, 3. solid feed cavity, 4. solid working belt, 5. hook working belt, 6. hook feed cavity, and 7. bolt. Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] A type of aluminum profile mold with hooks, combined with Figures 1 to 2 As shown, it includes a mold body 1, on which a pad 2 is provided to enhance the overall rigidity of the mold after extrusion and reduce the deformation of the aluminum profile. By adding a pad to the mold body, the overall rigidity of the mold after extrusion is enhanced, the mold deformation is reduced, and the mold maintains a stable shape during the extrusion process, providing a basis for the uniform extrusion of the profile.

[0018] A solid working belt 4 and a hook working belt 5 are provided between the pad plate 2 and the mold body 1 to extrude the aluminum profile. The solid working belt 4 and the hook working belt 5 are connected inside the mold body 1.

[0019] The fluid feed end of the solid part working belt 4 is provided with a solid part feed chamber 3. The edge of the solid part feed chamber 3 has a stepped structure to prevent the solid part from flowing too fast during the extrusion process. The stepped structure is used to prevent the solid part from flowing too fast during the production extrusion process, so as to avoid the solid part being extruded too fast and causing an imbalance between the flow rate and the hook part.

[0020] The feeding end of the working belt 5 of the hook section is provided with a hook section feeding chamber 6. The edge of the hook section feeding chamber 6 is a sloping structure, and the inclination angle of the hook section feeding chamber is 10°, which is used to accelerate the fluid flow of the hook section. The area of ​​the feeding chamber is increased to 5 times the area of ​​the original hook, thereby accelerating the flow of the hook section and making the two discharge flows of the solid part and the hook part uniform, so as to meet the dimensional requirements of the drawing.

[0021] Considering the significant differences in the thickness of the profiles, the length of the solid feed chamber 3 is set to 25mm to provide sufficient space for the metal material and create conditions for the uniform flow rate adjustment of different parts in the future. The length of the solid working belt 4 is 22mm to increase the friction during the extrusion process, thereby slowing down the flow rate during the extrusion process and further adjusting the extrusion speed of the solid part to match the flow rate of the hook part.

[0022] Bolts 7 are provided between the mold body 1 and the pad 2 to fix the mold body and the pad, so as to disassemble the mold body and the pad.

[0023] In this invention, when extruding aluminum alloy, fluid enters the solid working belt and hook working belt of the pad through the solid feeding chamber and hook feeding chamber, and converges in the mold body to extrude the aluminum profile with hooks.
