Description

Technical Field

[0001] This utility model relates to the field of hot extrusion die technology, and in particular to a hot extrusion die for conductive aluminum alloy profiles. Background Technology

[0002] Hot extrusion dies for conductive aluminum alloy profiles are key tools used in the production of conductive aluminum alloy profiles. They are dies that extrude aluminum alloy billets into conductive profiles of specific shapes at high temperatures. Hot extrusion dies for conductive aluminum alloy profiles are mainly used in scenarios where aluminum alloy profiles with conductive properties and specific cross-sectional shapes are produced through hot extrusion processes. They are widely used in the manufacturing of conductive structural components in fields such as electronics, power, rail transportation, and new energy.

[0003] When workers need to produce conductive aluminum alloy profiles, they place the blank on a hot extrusion die so that the die can shape the blank. However, the existing hot extrusion die will wear out during use because the blank will press against the die for a long time. Since the die is a single piece, workers need to replace the entire hot extrusion die, which causes inconvenience when replacing the die. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of inconvenience for workers when changing hot extrusion dies in the prior art, and to propose a hot extrusion die for conductive aluminum alloy profiles.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a hot extrusion die for conductive aluminum alloy profiles, comprising a first die, a second die disposed on one side of the first die, a die core disposed inside the first die, a die support seat disposed on the surface of the first die, the second die placed inside the die support seat, a replacement device disposed on the surface of the first die, the replacement device including a bayonet, the bayonet being formed on the surface of the first die, a storage groove being formed on the surface of the first die, the storage groove communicating with the bayonet, a limit plate rotatably connected inside the storage groove, and an anti-detachment block fixedly connected to the surface of the die core. The release block is placed inside the bayonet, and the limiting plate is placed on the surface of the anti-release block. The surface of the mold core has a positioning hole, which is located inside the first mold. The surface of the first mold has a threaded hole, which is aligned with the positioning hole. A threaded rod is threaded into the threaded hole, and the threaded rod is inserted into the interior of the positioning hole. The surface of the first mold is provided with a positioning component, which consists of a first pin and a pull spring. The first pin is slidably connected inside the first mold and is inserted into the slot on the surface of the limiting plate. The first pin can cooperate with the first mold and the limiting plate to restrict the rotation of the limiting plate.

[0006] Preferably, a pull spring is fixedly connected between the first pin and the first mold. The pull spring is located on one side of the limiting plate. The first pin can cooperate with the first mold and the pull spring to achieve the purpose of tightening the first pin.

[0007] Preferably, the surfaces of the first mold and the second mold are provided with an installation device, the installation device including a support plate, the support plate being fixedly connected to the surfaces of the first mold and the second mold, and a placement groove being provided on the inner side of the mold support base, the support plate being placed inside the placement groove, the support plate being able to cooperate with the first mold and the second mold to achieve the purpose of fixing the support plate.

[0008] Preferably, a second pin is inserted into the interior of the mold support base. The second pin is inserted into the interior of the support plate. One end of the second pin is fixedly connected to a storage block. The storage block is placed on the surface of the mold support base.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting up a replacement device, when the worker needs to replace the hot extrusion die, the worker pulls the first pin. The first pin is guided by the first die and disengages from the slot of the limiting plate. The worker rotates the limiting plate, which rotates 45 degrees clockwise inside the receiving slot. When the slot on the surface of the limiting plate aligns with the anti-detachment block, the worker releases the first pin, pulls the spring to pull the first pin, and the first pin resets and inserts into the slot of the limiting plate. The worker uses an auxiliary tool to rotate the threaded rod, which retracts inside the threaded hole and disengages from the positioning hole. The worker then removes the die core from the first die. By setting up the replacement device, the worker can effectively and conveniently replace the hot extrusion die, avoiding the need to replace the entire hot extrusion die, thus reducing the inconvenience encountered when replacing the hot extrusion die.

[0012] In this invention, by setting up an installation device, when the worker needs to install the first mold and the second mold, the first mold and the second mold are placed on the mold support base. The first mold and the second mold drive the support block to be placed in the placement groove. The worker inserts the second pin into the inside of the mold support base. The second pin drives the storage block to abut against the mold support base. The positioning plate is released, and the limit spring pulls the positioning plate. The positioning plate is guided by the guide rod, and the positioning plate slides and inserts into the storage block. By setting up the installation device, the worker can effectively and conveniently install the first mold and the second mold, avoiding the time-consuming situation when installing the first mold and the second mold, thereby improving the worker's work efficiency.

[0018] Specifically, the first mold 1 has a sliding connection of a first pin 37 inside. The first pin 37 is inserted into the slot on the surface of the limiting plate 39. The first pin 37 can cooperate with the first mold 1 and the limiting plate 39 to restrict the rotation of the limiting plate 39.

[0019] Specifically, a pull spring 38 is fixedly connected between the first pin 37 and the first mold 1, and the pull spring 38 is located on one side of the limiting plate 39.

[0020] In this embodiment, the first pin 37 can cooperate with the first mold 1 and the pull spring 38 to achieve the purpose of tightening the first pin 37.

Guided by the guide rod 44, the positioning plate 45 slides and inserts into the storage block 42. By setting up the installation device 4, it effectively facilitates the installation of the first die 1 and the second die 6, avoiding time-consuming installations and thus improving worker efficiency.
