Description

Technical Field

[0001] This utility model belongs to the field of aluminum profile extrusion molding technology, and specifically relates to an aluminum profile extrusion molding die. Background Technology

[0002] In the extrusion forming process of aluminum profiles, a die is required for extrusion forming. Therefore, the extrusion die plays a crucial role in the extrusion production of aluminum profiles and directly affects the quality of the extruded products. During the extrusion process, several streams of metal are extruded by the extruder and converge in the welding chamber. They are then re-welded in the high temperature, high pressure, and high vacuum die cavity to form a tube.

[0003] Chinese patent CN208628157U discloses an aluminum profile extrusion molding die. The aluminum profile extrusion molding die provided by this utility model ensures equal pressure of the metal flow throughout the forming hole, resulting in high-quality aluminum profiles that are extruded through the forming hole after forming, thus reducing twisting and deformation during the aluminum profile extrusion process.

[0004] The aforementioned equipment suffers from temperature inconsistencies between the upper and lower dies due to the upper die contacting the aluminum profile rod during use and generating friction during diversion. This temperature difference can increase thermal stress on the die, accelerating wear and deformation, and shortening its lifespan. Furthermore, uneven temperature distribution can lead to uneven flow of the aluminum profile during extrusion, affecting extrusion precision and surface quality. Additionally, after the diverted molten aluminum enters the secondary welding chamber, design or manufacturing precision issues may cause a time lag in the aluminum's entry into the forming hole. This lag can result in poor fusion of the aluminum profile in the welding area, leading to weld defects such as slag inclusions and porosity, thus affecting the overall strength and sealing performance of the aluminum profile. Utility Model Content

[0005] The purpose of this invention is to provide an aluminum profile extrusion forming die to solve the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An aluminum profile extrusion die includes an upper die with a die core embedded in its center. A lower die is located on one side of the upper die. A uniformly distributed heat-conducting block is disposed between the upper and lower dies. A uniformly arranged heat-conducting rod is inserted into one side of each heat-conducting block. The upper die has uniformly distributed flow-diverting holes and a uniformly distributed groove on one side, with the heat-conducting block inserted inside the groove. The heat-conducting block and heat-conducting rod are used to conduct heat to the lower die. A flow-guiding block one and a flow-guiding block two are located on one side of the lower die. The flow-guiding block two is located on both sides of the flow-guiding block one and is used to cooperate with the upper die. The flow-guiding block one and the flow-guiding block two are used to guide and divert the aluminum metal.

[0008] Preferably, the lower mold has a primary welding chamber on the side near the upper mold, the primary welding chamber is used for partial embedding of the upper mold, and the lower mold has uniformly distributed mounting slots on its periphery.

[0009] Preferably, the primary welding chamber has uniformly arranged insertion holes that fit the heat-conducting rod, and a secondary welding chamber is provided in the middle of the primary welding chamber for guiding molten metal.

[0010] Preferably, the first guide block and the second guide block are fixedly connected to the inner wall of the secondary welding chamber, and the second guide block is inclined to the first guide block.

[0011] Preferably, a forming groove is provided at the center of the secondary welding chamber, and the forming groove is used for the molten metal to be formed.

[0012] Preferably, the slot has an insert plate installed inside, and the insert plate has evenly distributed mating holes that fit the heat-conducting rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] I. This utility model effectively conducts the heat generated by the aluminum profile rod during the extrusion process by setting a heat-conducting block and a heat-conducting rod between the upper and lower dies, making the temperature of the upper and lower dies more uniform. This reduces the thermal stress caused by temperature difference, thereby extending the service life of the die, ensuring the uniform flow of the aluminum profile during the extrusion process, and improving the extrusion accuracy and surface quality.

[0015] Second, the arrangement of the first and second guide blocks of this utility model, and their cooperation with the secondary welding chamber, enables the diverted aluminum molten metal to flow more concentratedly and evenly to the gap between the outer periphery of the mold core and the forming groove. This reduces the time difference when the aluminum metal enters the forming hole, thereby improving the fusion quality of the aluminum profile in the welding area, reducing the occurrence of weld defects (such as slag inclusions, porosity, etc.), and improving the overall strength and sealing performance of the aluminum profile.

[0027] The heat-conducting block 4 and the heat-conducting rod 5 are used to conduct heat to the downward mold 3;

[0028] The lower mold 3 is provided with a flow guide block 1 35 and a flow guide block 2 36 on one side. The flow guide block 2 36 is located on both sides of the flow guide block 1 35. The flow guide block 1 35 and the flow guide block 2 36 are used to cooperate with the upper mold 1. The flow guide block 1 35 and the flow guide block 2 36 are used to concentrate and guide the flow of aluminum metal. The upper mold 1, the mold core 2 and the lower mold 3 are all existing technologies.

[0029] In a further embodiment, a primary welding chamber 31 is provided on the side of the lower mold 3 near the upper mold 1. The primary welding chamber 31 is used for partial embedding of the upper mold 1. Uniformly distributed mounting slots 37 are provided on the periphery of the lower mold 3.

[0030] In this embodiment, the upper mold 1 has a slot at its center for installing the mold core 2, and both the upper mold 1 and the lower mold 3 have shaft holes for mutual docking.

[0031] In a further embodiment, the primary welding chamber 31 has uniformly arranged insertion holes 32 that fit the heat-conducting rod 5, and a secondary welding chamber 33 is provided in the middle of the primary welding chamber 31 for guiding the molten metal.

[0032] In this embodiment, the insertion hole 32 is used for inserting the heat-conducting rod 5, thereby transferring heat.

[0033] In a further embodiment, guide block 1 35 and guide block 2 36 are fixedly connected to the inner wall of the secondary welding chamber 33, and guide block 2 36 is inclined to guide block 1 35.

[0034] In this embodiment, the first guide block 35 and the second guide block 36 are located at the inlet port of the diversion hole 11.

[0035] In a further embodiment, a forming groove 34 is provided at the center of the secondary welding chamber 33, and the forming groove 34 is used for the molten metal to be formed.

[0036] In this embodiment, after entering the interior of the secondary welding chamber 33, the mold core 2 passes through the gap between the outer periphery and the forming groove 34, thus forming the mold.

[0039] The working principle of this utility model is as follows:

[0040] When aluminum profile rod forming is required, external equipment needs to heat the upper mold 1 and the lower mold 3. After the aluminum profile rod passes through the hot extrusion from one side of the upper mold 1, it will be diverted by the diversion hole 11 and enter the interior of the secondary welding chamber 33. The aluminum profile rod can be diverted a second time by the guide block 1 35 and the guide block 2 36, thereby forming through the gap between the mold core 2 and the forming groove 34.

[0041] When the aluminum profile rod passes through the diversion hole 11, the heat generated by the extrusion of the aluminum profile rod can be conducted to the upper die 1, and then from the upper die 1 to the heat-conducting block 4 inside the groove 12, and then through the heat-conducting block 4 and the heat-conducting rod 5 to the interior of the lower die 3, so that the temperature of the two dies is more uniform during the extrusion of the aluminum profile rod.

[0042] After the aluminum profile rod is diverted by the diversion hole 11 and enters the interior of the secondary welding chamber 33, the liquid aluminum liquid will be guided by the first guide block 35 and the second guide block 36, so that it flows more concentratedly to the gap between the outer periphery of the mold core 2 and the forming groove 34.
