Description

Technical Field

[0001] This utility model belongs to the field of aluminum profile processing, and in particular relates to a low-temperature extrusion die for aluminum profiles that is easy to form. Background Technology

[0002] Aluminum profiles are aluminum materials that are produced by melting and extruding aluminum rods to obtain different cross-sectional shapes. The production process of aluminum profiles mainly includes three processes: melting and casting, extrusion, and coloring. Extrusion is the process of melting aluminum rods and then pressing them into a mold to form the desired shape.

[0003] A published patent, CN222740124U, discloses an aluminum profile extrusion mold, including a support frame. A hydraulic press is fixedly mounted on the top surface of the support frame, and a hydraulic rod is mounted on one end of the hydraulic press. A connecting block is inserted into one end of the hydraulic rod, and the connecting block is detachably connected to the hydraulic rod by fastening bolts. A pressure plate is mounted on the bottom surface of the connecting block. A mold is set on the top surface of the support frame, and fixing blocks are fixedly mounted on both sides of the mold on the top surface of the support frame. Clamps are used in conjunction on the two fixing blocks. This utility model uses an electric push rod and a lifting plate in conjunction. During the aluminum profile extrusion process, the lifting plate is located inside and below the mold. After the aluminum profile is extruded, the electric push rod extends and pushes the lifting plate upward, pushing the extruded aluminum profile out of the mold for easy unloading. After unloading, the electric push rod retracts and resets, ready for the next unloading. Unloading is more convenient and labor-saving, and it is highly practical. By using an electric push rod to drive the lifting plate upward to push the profile out of the mold, unloading is automated to a certain extent, reducing the intensity of manual operation. However, this structure requires additional electric actuators and corresponding control systems, which increases the manufacturing cost of the equipment and the difficulty of subsequent maintenance. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a low-temperature extrusion die for aluminum profiles that is easy to form. It eliminates the need for additional drive devices and control systems, thereby reducing manufacturing costs and post-maintenance difficulties. Furthermore, it facilitates ejection by naturally achieving the ejection action during the die opening process, improving automation while reducing energy consumption.

[0005] In view of this, the present invention provides a low-temperature extrusion die for aluminum profiles that is easy to form, comprising:

[0006] The base has a gantry frame fixed on top, the gantry frame is connected to an upper mold via a telescopic component, and the base is provided with a lower mold that corresponds to and is adapted to the upper mold;

[0007] A linkage mechanism, located between the upper and lower molds, is used to automatically eject the aluminum profile from the lower mold during mold opening. The linkage mechanism includes:

[0008] A top plate is located inside the cavity of the lower mold. A top post is fixed to the bottom of the top plate. The top post slides through the bottom of the lower mold and extends below it. A connecting plate is fixed to the bottom of the top post.

[0009] Two mounting plates are fixed to both ends of the upper mold;

[0010] Two lifting rods are fixed on both sides of the connecting plate near the mounting plate, and slide through the two mounting plates respectively. A limit plate is fixed on the top of the rods.

[0011] In this technical solution, the aluminum profile is ejected from the top plate by linkage between the upper mold opening action and the upper mold opening action. There is no need to configure additional drive devices and control systems, which simplifies the overall structure, reduces manufacturing costs and post-maintenance difficulty. At the same time, the ejection action is naturally achieved by the mold opening process, which improves the degree of automation and reduces energy consumption.

[0012] Furthermore, the telescopic assembly includes an electric hydraulic cylinder fixedly connected to the top of the gantry frame, and the telescopic end of the electric hydraulic cylinder slides through the gantry frame and is fixedly connected to the top center of the upper mold.

[0013] In this technical solution, the driving force of the electric hydraulic cylinder is stable and precisely controlled, which can adapt to the forming requirements of low temperature extrusion of aluminum profiles, ensuring that the extrusion action of the upper mold is smooth and reliable. At the same time, it works in coordination with the linkage mechanism to achieve precise extrusion forming. Simultaneously, the ejection function is triggered by the mold opening action, which improves the overall operation efficiency and ease of operation.

[0014] Furthermore, a connecting groove is provided at the bottom center of the lower mold, and a through hole is provided at the bottom center of the inner cavity of the lower mold. The through hole is interconnected with the mold cavity and the connecting groove of the lower mold, and the top post is slidably connected in the through hole.

[0015] In this technical solution, the through hole provides precise guidance for the top column, which can prevent the top column from deviating during the ejection process, ensure the stable and accurate ejection action of the top plate, and prevent the aluminum profile from deforming due to uneven force during ejection. The connection design between the connecting groove and the through hole can not only provide a space for the bottom structure of the top column, but also reduce the structural interference between the top column and the lower mold, improve the smoothness of the linkage mechanism, achieve stable action without additional guiding components, further simplify the structure and reduce maintenance requirements.

[0016] Furthermore, the bottom ends of the lower molds on both sides of the connecting groove are fixedly connected to base plates, and the bottom of the base plates are fixedly connected to the base.

[0017] In this technical solution, the lower mold is securely connected to the base plate, while providing ample space for the movement of the connecting plate.

[0018] Furthermore, reset springs are fixedly connected to both sides of the bottom of the connecting plate and the base.

[0019] In this technical solution, the reset spring, by virtue of its own elasticity, can automatically reset the connecting plate and the top plate to their initial positions after the mold opening and ejection action is completed, thus achieving the reset function without the need for additional driving components.

[0020] Furthermore, the inner cavity of the gantry frame is provided with limit grooves at both ends, and limit blocks are slidably connected in both limit grooves. Connecting rods are fixedly connected between the two limit blocks and both ends of the connecting plate.

[0021] In this technical solution, the sliding fit between the limiting groove and the limiting block, through the connecting rod, forms a precise guide for the movement of the connecting plate, which can effectively limit the offset of the connecting plate during the lifting process and ensure that the ejection action of the top column and the top plate always remains stable and precise.

[0022] The beneficial effects of this utility model are:

[0023] 1. When the upper mold rises, the mounting plate drives the lifting rod to pull the connecting plate, so that the top column lifts the top plate. There is no need to configure an independent electric push rod and control system, which reduces the equipment manufacturing cost from the source. Moreover, the linkage mechanism is composed of mechanical parts without complex circuits or sensors. Daily maintenance only requires checking the mechanical connection, which reduces the difficulty of later maintenance.

[0024] 2. In this utility model, when the mold is opened, the upper mold drives the lifting rod to rise, and the connecting plate stretches the reset spring to store elastic potential energy; when the mold is closed, the spring contracts to release potential energy, driving the top column and the top plate to fall back automatically, ensuring that the top plate is accurately reset to the bottom of the mold cavity, and avoiding defects in the next extrusion forming caused by incomplete reset.

[0025] 3. This utility model is designed so that the limiting block slides along the limiting groove, and the connecting rod restricts the connecting plate to only make vertical movements, ensuring that the top column and lifting rod always move along the axis. This avoids the jamming problem caused by the skew of the linkage parts in the unguided structure, reduces downtime due to failure, and at the same time the guiding structure ensures that the top plate is evenly stressed when ejecting the profile, ensuring that the profile does not deform after low temperature extrusion and improving the product qualification rate.

Additionally, features described with reference to certain examples may be combined in other examples.

[0035] Example 1:

[0036] like Figure 1-3 As shown, this utility model provides a low-temperature extrusion die for easy forming of aluminum profiles, comprising:

[0037] The base 1 has a gantry frame 11 fixed on its top. The gantry frame 11 is connected to an upper mold 31 through a telescopic component. The base 1 is provided with a lower mold 2 that is adapted to the upper mold 31.

[0038] A linkage mechanism, located between the upper mold 31 and the lower mold 2, is used to automatically eject the aluminum profile from the lower mold 2 when the mold is opened. The linkage mechanism includes:

[0039] A top plate 45 is disposed in the cavity of the lower mold 2. A top post 44 is fixed at the bottom of the top plate 45. The top post 44 slides through the bottom of the lower mold 2 and extends below it. A connecting plate 4 is fixed at the bottom of the top post 44.

[0040] Two mounting plates 43 are fixed to both ends of the upper mold 31;

[0041] Two lifting rods 41 are fixed on both sides of the connecting plate 4 near the mounting plate 43, and slide through the two mounting plates 43 respectively. A limit plate 42 is fixed on the top of the rods.

[0042] When the upper mold 31 rises, the mounting plate 43 drives the lifting rod 41 to pull the connecting plate 4, so that the top column 44 lifts the top plate 45. There is no need to configure an independent electric push rod and control system, which reduces the equipment manufacturing cost from the source. Moreover, the linkage mechanism is composed of mechanical parts, without complex circuits or sensors. Daily maintenance only requires checking the mechanical connection, which reduces the difficulty of later maintenance.

[0043] The telescopic assembly includes an electric hydraulic cylinder 3 fixedly connected to the top of the gantry frame 11. The telescopic end of the electric hydraulic cylinder 3 slides through the gantry frame 11 and is fixedly connected to the top center of the upper mold 31.

[0044] The electric hydraulic cylinder 3 drives the upper mold 31 to rise and fall precisely. Its rising action can be directly transmitted to the linkage mechanism through the mounting plate 43 and the lifting rod 41, so that the rising force of the upper mold 31 is synchronously converted into the ejection power, ensuring the stable ejection of the profile.

[0045] The lower mold 2 has a connecting groove 22 at the bottom center and a through hole 23 at the bottom center of the inner cavity of the lower mold 2. The through hole 23 is connected to the mold cavity and the connecting groove 22 of the lower mold 2. The top post 44 is slidably connected in the through hole 23.

[0046] The top column 44 slides along the through hole 23, which can strictly limit its vertical movement to ensure that the top plate 45 is evenly stressed when ejecting the profile, avoiding ejection failure caused by the bending of the top column 44 in the unguided structure, and protecting the profile forming accuracy; and the connecting groove 22 provides the connecting plate 4 with the moving space, so that the connecting plate 4 can move up and down with the top column 44 when it is raised and lowered, avoiding the base 1 directly obstructing the movement of the top column 44.

[0047] The bottom ends of the lower molds 2 on both sides of the connecting groove 22 are fixedly connected to the bottom plates 21, and the bottom of the bottom plates 21 are fixedly connected to the base 1.

[0048] The lower mold 2 is stably supported by the base plate 21, and the bottom of the lower mold 2 is raised to provide sufficient space for the connecting groove 22 and the connecting plate 4 to ensure that the top column 44 can be fully extended.

[0049] Example 2:

[0050] like Figure 1-2 As shown, reset springs 5 ​​are fixedly connected to the base 1 on both sides of the bottom of the connecting plate 4.

[0051] When the mold opens, the upper mold 31 drives the lifting rod 41 to rise, and the connecting plate 4 stretches the reset spring 5 to store elastic potential energy; when the mold closes, the spring contracts and releases potential energy, driving the top pillar 44 and the top plate 45 to automatically fall back, ensuring that the top plate 45 is accurately reset to the bottom of the mold cavity, avoiding defects in the next extrusion forming caused by incomplete reset.

[0052] The inner cavity of the gantry frame 11 has limit grooves 6 at both ends, and limit blocks 61 are slidably connected in both limit grooves 6. Connecting rods 62 are fixedly connected between the two limit blocks 61 and both ends of the connecting plate 4.

[0053] By sliding the limiting block 61 along the limiting groove 6, and cooperating with the connecting rod 62, the connecting plate 4 is restricted to only make vertical movements, ensuring that the top column 44 and the lifting rod 41 always move along the axis, avoiding the jamming problem caused by the skew of the linkage components in the unguided structure, reducing downtime due to malfunctions. At the same time, the guiding structure ensures that the top plate 45 is evenly stressed when it pushes out the profile, ensuring that the profile does not deform after low-temperature extrusion and improving the product qualification rate.

[0054] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
