Description

Technical Field

[0001] This utility model relates to the field of molding die technology, specifically to an insert-type aluminum profile die. Background Technology

[0002] my country's automotive industry has experienced rapid development, with a significant increase in the number of vehicles. In particular, energy consumption is rising rapidly. To reduce energy consumption and promote energy conservation and emission reduction, the automotive industry is moving towards lightweight design. Aluminum alloys, due to their light weight, aesthetic appeal, good thermal conductivity, and ease of processing into complex shapes, are widely used in various stages of industrial production and in the field of new energy vehicles. However, if hard aluminum is used as the aluminum profile material, the surface of the aluminum profile becomes very rough during extrusion, and the working zone of the die suffers severe wear, affecting the surface quality of the product. This results in a high rate of product scrap and die failure, significantly increasing costs. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an insert-type aluminum profile mold that can reduce mold wear during the aluminum profile forming process and improve product forming quality.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0005] An insert-type aluminum profile mold includes a mold, a mold feeding cavity at the top of the mold, an embedding groove at the bottom of the mold, an insert installed in the embedding groove, and a working belt inside the insert; a mold discharge cavity at the bottom of the insert; and a pad at the bottom of the mold to prevent the insert from falling out of the mold bottom embedding groove, with a pad discharge cavity at the center of the pad.

[0006] The above-mentioned insert-type aluminum profile mold has a mold feeding cavity that is arranged in a downward tapering manner, the inner wall of the mold feeding cavity is a first guide wall that is arranged downwardly, and the top of the mold feeding cavity is provided with a chamfer.

[0007] In the aforementioned insert-type aluminum profile mold, the bottom dimension of the mold's feed chamber is larger than the dimension of the working belt but smaller than the dimension of the insert.

[0008] In the aforementioned embedded aluminum profile mold, the size of the mold's discharge cavity is larger than the size of the working belt.

[0009] In the aforementioned embedded aluminum profile mold, the discharge cavity of the pad plate has a downwardly expanding structure.

[0010] The aforementioned insert-type aluminum profile mold has a guide cavity at the center of the insert above the working belt, and the inner wall of the guide cavity is a second guide wall that is inclined downwards.

[0011] Due to the adoption of the above technical solutions, the technological progress achieved by this utility model is as follows.

[0012] This utility model provides an insert-type aluminum profile mold. By inserting a detachable insert at the bottom of the mold and setting the working belt inside the insert, it solves the problem of poor product quality caused by severe wear of the working belt during the mold forming process. At the same time, after the working belt wears out, it is not necessary to scrap the entire mold; only the worn insert needs to be replaced, thus reducing the mold maintenance cost. By setting a downward-sloping first guide wall and a second guide wall, impurities in the aluminum rod can be filtered out, preventing impurities from entering the forming working belt, accelerating the flow of the aluminum profile, solving the problem of rough surface of the formed profile, and improving the forming quality of the product. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the specific structure of the present utility model; Figure 2 This is a top view of the present invention; Figure 3 This is a side sectional view of the present invention.

[0014] Among them: 1. mold, 2. backing plate, 3. insert, 4. mold feeding cavity, 5. mold discharge cavity, 6. working belt, 7. guide cavity, 8. backing plate discharge cavity, 9. chamfer, 10. first guide wall, 11. second guide wall. Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] An embedded aluminum profile mold, such as Figures 1 to 3 As shown, the mold includes a mold 1. The top of the mold 1 has a mold feeding cavity 4, which is tapered downwards. The bottom of the mold 1 has an embedding groove, in which an insert 3 is installed. The insert 3 has a working belt 6 inside. The size of the bottom of the mold feeding cavity 4 is larger than the size of the working belt 6 but smaller than the size of the insert 3. The bottom of the insert 3 has a mold discharge cavity 5, which is larger than the size of the working belt 6. The bottom of the mold 1 has a pad 2, which prevents the insert 3 from coming out of the embedding groove at the bottom of the mold 1. The center of the pad 2 has a gradually expanding pad discharge cavity 8.

[0017] The inner wall of the mold feeding cavity 4 is a first guide wall 10 that is inclined downwards. The top of the mold feeding cavity 4 is provided with a chamfer 9. When the aluminum alloy material gradually transitions to the bottom of the mold feeding cavity 4 through the cooperation of the chamfer 9 and the first guide wall 10, some impurities in the aluminum rod are left in the dead corner between the bottom of the mold feeding cavity and the top of the insert when the aluminum alloy material flows through the bottom.

[0018] The insert 3 located above the working belt 6 has a guide cavity 7 at its center. The inner wall of the guide cavity 7 is a second guide wall 11 that is inclined downwards. The inclination of the second guide wall 11 increases the friction of the aluminum alloy hard material, thereby drawing out the particles in the aluminum alloy hard material and increasing the flow of the aluminum profile.

[0019] Since the mold forming working zone is located inside the insert 3, and the insert 3 can be detachably installed in the embedding groove at the bottom of the mold 1, when the wear dimension of the mold surface working zone exceeds the set error, as long as this insert is scrapped, the overall mold can still be used normally. It is very convenient to process and replace the insert in the future.

[0020] In this embodiment, the insert 3 can be connected to the mold 1 through the cooperation of the pin and the pin hole, thereby ensuring the stable existence of the insert. In other embodiments, the insert 3 can be directly embedded into the insert groove and supported and limited by the pad to prevent the insert from moving. Alternatively, other structures that can lock the insert to the mold can be selected.

[0021] Moreover, the setting of the first and second guide walls allows impurities in the aluminum rod to be filtered during the forming process, accelerating the flow of the aluminum profile and solving the problem of rough surface of the profile during the existing mold processing.

[0022] Moreover, during the discharge process, since the size of the mold discharge cavity is larger than the size of the working belt, and the pad discharge cavity is set in a downward gradually expanding structure, when the product is formed and discharged inside the working belt, the mold discharge cavity and the pad discharge cavity do not come into contact with the formed product, and there will be no problem of product quality being affected by friction with the product surface during the discharge process.

[0023] This utility model provides an insert-type aluminum profile mold. By inserting a detachable insert at the bottom of the mold and setting the working belt inside the insert, it solves the problem of poor product quality caused by severe wear of the working belt during the mold forming process. At the same time, after the working belt wears out, it is not necessary to scrap the entire mold; only the worn insert needs to be replaced, thus reducing the mold maintenance cost. By setting a downward-sloping first guide wall and a second guide wall, impurities in the aluminum rod can be filtered out, preventing impurities from entering the forming working belt, accelerating the flow of the aluminum profile, solving the problem of rough surface of the formed profile, and improving the forming quality of the product.
