Description

Technical Field

[0001] The present application relates to the technical field of aluminum profile extrusion dies, and in particular to a wear-resistant aluminum profile extrusion die. Background Art

[0002] Aluminum is a metal with low strength and good plasticity. In addition to the application of some pure aluminum, in order to improve the strength or comprehensive performance, by adding an alloy element to the aluminum, its structure and performance can be changed, making it suitable for various processed materials or casting parts. The processing of aluminum profiles is generally prepared by direct extrusion using a mold.

[0003] At present, in the production process of aluminum profiles, extrusion dies play a vital role. After long-term use, traditional aluminum profile extrusion dies are prone to excessive mold temperature due to heat accumulation inside the mold, which not only affects the molding quality of aluminum profiles, such as causing profile size deviation, increased surface roughness and other problems, but also reduces the service life of the mold. At the same time, traditional molds are cumbersome to disassemble and install, requiring a lot of time and manpower, which seriously affects production efficiency.

[0004] Through searching, Chinese patent announcement number CN115318864A discloses an aluminum extrusion die. The aluminum extrusion die includes an upper die plate and a lower die plate, the upper die plate is located on one side of the lower die plate, a discharge hole is provided in the middle of one side of the upper die plate, a feed hole is provided in the middle of one end of the lower die plate, the feed hole is arranged in parallel with the discharge hole, a cutting blade is arranged on the side of the feed hole away from the discharge hole, the cutting blade is arranged in an annular shape, the diameter surrounded by the cutting blade is larger than the diameter of the feed hole, and the end of the cutting blade is arranged in a flat shape. Through the arrangement of the cutting blade, when the heated raw material is aligned with the feed hole, the outer side of the raw material will contact the flat cutting blade during extrusion. Since the raw material is in a high temperature and easy to process state at this time, as the raw material is extruded, a thin layer of the outer side will be shaved off by the cutting blade, thereby peeling off the outer layer of the raw material contaminated by external dust and particles, effectively improving the subsequent product quality.

[0005] With regard to the above-mentioned related technologies, the inventors believe that the following defects exist: after long-term use, the extrusion die will easily become too hot due to heat accumulation inside the die, which will not only affect the molding quality of the aluminum profile, such as causing profile size deviation, increased surface roughness and other problems, but also reduce the service life of the die. At the same time, the traditional mold is cumbersome to disassemble and install, which requires a lot of time and manpower, seriously affecting production efficiency. Therefore, the development of an aluminum profile extrusion die that can effectively dissipate heat and is easy to disassemble and install quickly has become a technical problem that needs to be solved urgently.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-12 This application is described in further detail.

[0032] The embodiment of the present application discloses a wear-resistant aluminum profile extrusion die, comprising a left die 1 and a right die 2, wherein a plurality of diversion holes 3 are opened in the left die 1 along the axial direction, a mold core 4 is fixedly arranged on the right side surface of the left die 1, a welding chamber 5 is opened on the left side surface of the right die 2, and a forming hole 6 matching the shape of the mold core 4 is opened on the inner bottom wall of the welding chamber 5 of the right die 2, the left die 1 and the right die 2 are both arranged in a fixed frame 7, the right side surface of the left die 1 and the left side surface of the right die 2 are fitted together, the mold core 4 is located in the forming hole 6, and a forming chamber is formed between the outer surface of the mold core 4 and the inner side wall of the forming hole 6; when in use, the aluminum profile bar is pushed by an external force after being heated and forced into from the left side surface of the left die 1, the aluminum profile bar is diverted, and the diversion hole 3 guides the metal of the aluminum profile bar to the periphery of the mold core 4; the metal entering the welding chamber 5 of the right die 2 is welded together and extruded from the forming chamber formed by the mold core 4 and the forming hole 6 to form a formed aluminum profile; and the processing of the aluminum profile is completed.

[0033] When the left mold 1 and the right mold 2 are in use, they need to be fixed in the fixing frame 7, and the right side surface of the left mold 1 and the left side surface of the right mold 2 are tightly fitted to ensure the sealing of the welding chamber on the right mold 2. However, during use, due to the extrusion pressure of the aluminum bar, a rightward thrust is generated on the right mold 2, causing the right mold 2 to tend to separate from the left mold 1. After long-term use, the mechanism of the fixing frame 7 that fixes the left mold 1 and the right mold 2 becomes loose, which in turn causes a gap between the right mold 2 and the left mold 1, resulting in reduced welding quality, and even the generation of welds and defective products.

[0034] In order to solve the above technical problems, in this embodiment, a locking device is provided in the right mold 2 and the left mold 1. The locking device is used to further lock the left mold 1 and the right mold 2 when the aluminum profile bar is squeezed into the diversion hole 3, thereby ensuring that the left mold 1 and the right mold 2 are tightly fitted during use, thereby improving the molding quality of the aluminum profile and reducing the scrap rate.

[0035] In this embodiment, the locking device includes a plurality of locking rods 8 uniformly and fixedly arranged around the welding chamber on the left side of the right mold 2, and a plurality of locking cavities 9 corresponding to the locking rods 8 are opened on the right side of the left mold 1. The locking cavities 9 are arranged corresponding to the diversion holes 3, and each locking rod 8 is inserted into the corresponding locking cavity 9; an accommodating cavity 10 is opened on the inner side wall of the diversion hole 3 of the left mold 1, and an extrusion plate 11 is arranged in the accommodating cavity 10. A locking rod 12 is fixedly arranged on the outer side of the extrusion plate 11, and the outer end of the locking rod 12 extends into the locking cavity 9 and is fixedly provided with a locking head 13. The inner side wall of the locking cavity 9 and the position corresponding to the locking head 13 are opened to accommodate The locking rod 12 of the receiving groove 14 is provided with a spring 15, the top end of the spring 15 is fixedly arranged with the clamping head 13, and the bottom end of the spring 15 is fixed on the inner bottom wall of the receiving chamber; the upper end surface of the clamping head 13 is provided with two symmetrical inclined surfaces 16; the clamping rod 8 is provided with a locking groove 17 adapted to the clamping head 13 at a position close to the center of the right mold 2; when in use, the clamping rod 8 of the right mold 2 is inserted into the corresponding clamping cavity 9, and the end of the clamping rod 8 drives the inclined surface 16 of the clamping head 13 so that the clamping head 13 drives the extrusion plate 11 to move into the diverter hole 3 through the locking rod 12, and the clamping head 13 is pressed into the receiving groove 1 4 and compress the spring 15. When the clamping head 13 is aligned with the locking groove 17 on the clamping rod 8, the clamping head 13 is driven by the spring 15 to move outward into the locking groove 17, so that the left mold 1 and the right mold 2 are locked; then the left mold 1 and the right mold 2 are fixed in the fixing frame 7; after being heated, the aluminum bar is pushed by an external force and forced into from the left side of the left mold 1, the aluminum bar is diverted, and the metal of the aluminum bar flows into each diversion hole 3. The metal further squeezes the extrusion plate 11, so that the clamping head 13 is pushed into the locking groove 17 more tightly, and the diversion hole 3 guides the metal of the aluminum bar to the periphery of the mold core 4; enter The metal in the welding chamber 5 of the right mold 2 is welded together and extruded from the molding cavity formed by the mold core 4 and the molding hole 6 to form a molded aluminum profile. The metal exerts a rightward thrust on the right mold 2, causing the clamping rod 8 to move rightward and extrude the clamping head 13 downward. However, since the metal in the diversion hole 3 squeezes the extrusion plate 11, the clamping head 13 is prevented from moving inward, forming a self-locking. After the fixing frame 7 fixes the left mold 1 and the right mold 2, the purpose of self-locking of the left mold 1 and the right mold 2 is further achieved, ensuring that no gap is generated between the left mold 1 and the right mold 2 during use, ensuring the quality of aluminum profile processing, and reducing the defective rate.When the mold needs to be replaced after use, the operator first removes the right mold 2 from the fixing frame 7 to separate the right mold 2 and the left mold 1, because the aluminum profile bar in the mold still has residual temperature at this time, and the ductility of aluminum is relatively good; during the disassembly of the right mold 2, the clamping head 13 is pressed down into the receiving groove 14 through the clamping rod 8; the clamping head 13 presses the extrusion plate 11 downward to squeeze the aluminum profile bar, so that a gap is generated between the inner wall of the diverter hole 3 and the aluminum profile bar; then the left mold 1 is disassembled; both the left mold 1 and the right mold 2 are immersed in the demoulding liquid; the demoulding liquid flows into the diverter hole 3 from the clamping cavity 9. Since a gap is generated between the inner wall of the diverter hole 3 and the aluminum profile bar, the demoulding liquid can more easily invade the gap between the diverter hole 3 and the aluminum profile bar, which is convenient for demoulding the aluminum profile bar remaining in the clamping cavity 9.

[0036] In the production process of aluminum profiles, after the mold is used for a long time, due to the accumulation of heat inside the mold, it is easy to cause the mold temperature to be too high, the surface roughness to increase, the fluidity of the metal is affected, and then the molding quality of the aluminum profile is affected, and the service life of the mold is reduced. In order to solve this problem, in this embodiment, a center hole 18 is opened in the locking rod 8, and a vent hole 19 connected to the center hole 18 is opened on the left part of the outer surface of the locking rod 8. The outer surface of the left mold 1 is provided with a heat dissipation hole 20 connected to the locking cavity 9. When the locking rod 8 is inserted into the corresponding locking cavity 9, the bottom end of the heat dissipation hole 20 is connected to the top end of the vent hole 19; when in use, the heat of the metal in the diversion hole 3 is transferred to the extrusion plate 11, the locking rod 12 and the locking head 13 in turn, the heat on the locking head 13 is dissipated into the center hole 18 through the locking rod 8, and the heat in the center hole 18 is dissipated to the outside through the vent hole 19 and the heat dissipation hole 20, so as to achieve the purpose of effective heat dissipation inside the mold.

[0037] In this embodiment, the fixing frame 7 includes a bottom plate 21 and a side plate 22 fixedly arranged on the upper end surface of the bottom plate 21, two limit plates 23 are fixedly arranged on the inner side surface of the side plate 22 in the vertical direction, and a mounting plate 24 is fixedly arranged inside the two limit plates 23, and a bottom support plate 25 and a top cover plate 26 are fixedly arranged on the inner side surface of the mounting plate 24, and a slide groove is formed between the bottom support plate 25 and the top cover plate 26, and a pin hole 27 is provided on the top cover plate 26. Slide blocks 28 are fixedly arranged on the outer surfaces of the left mold 1 and the right mold 2, and a plug hole 29 is provided on the upper end surface of the slide block 28 located on the right mold 2; when in use, the slide block 28 on the left mold 1 is slid into the corresponding slide groove from the right side and contacts the right side surface of the limit plate 23 on the left side; so that the left mold The tool 1 is located at the front side of the fixing frame 7, and then the right mold 2 is slid from the right side into the slide groove between the bottom support plate 25 and the top cover plate 26, and each locking rod 8 is inserted into the corresponding locking cavity 9 of the left mold 1, and then the latch is inserted into the pin hole 27 of the top cover plate 26 and the socket 29 of the slider 28 on the right mold 2 to fix the right mold 2; at the same time, the left mold 1 is fixed; after long-term use, the matching clearance between the latch and the pin hole 27 and the socket 29 is too large, and when the aluminum profile is extruded, a gap appears on the contact surface of the left mold 1 and the right mold 2, and the left mold 1 and the right mold 2 are further locked through the cooperation of the locking rod 8 and the locking head 13 to prevent a gap from appearing between the left mold 1 and the right mold 2.

[0038] In this embodiment, a notch 30 is formed between the top cover plate 26 and the limiting plate 23 on the front side, and the height of the slider 28 fixed on the left mold 1 is greater than the width of the slide groove; when in use, the slider 28 on the left mold 1 can be placed into the slide groove from top to bottom through the notch 30, and then the slider 28 on the right mold 2 slides into the slide groove from the right side, and then the latch is inserted into the pin hole 27 of the top cover plate 26 and the plug hole 29 of the slider 28 on the right mold 2 to fix the right mold 2; at this time, the slider 28 on the left mold 1 is restricted in the notch 30; when the mold needs to be replaced after use, the operator first pulls out the latch, inserts a tool into the pin hole 27 and pries the right mold 2 toward the outside of the fixing frame 7, so that the right mold 2 drives the clamping rod 8 to be pulled out of the clamping cavity 9 of the left mold 1. At this time, the left mold 1 is The slider 28 is restricted in the notch 30 and will remain stationary. Since the aluminum bar in the mold still has residual temperature at this time and the ductility of aluminum is good, during the disassembly of the right mold 2, the clamping head 13 is pressed down by the clamping rod 8; the clamping head 13 presses down the extrusion plate 11 to extrude the metal in the diverter hole 3, so that a gap is generated between the inner wall of the diverter hole 3 and the aluminum bar; then the left mold 1 is clamped and pulled upward, so that the slider 28 of the left mold 1 slides upward out of the notch 30, and the disassembly of the left mold 1 is completed; both the left mold 1 and the right mold 2 are immersed in the demoulding liquid; the demoulding liquid flows into the diverter hole 3 from the clamping cavity 9. Since a gap is generated between the inner wall of the diverter hole 3 and the aluminum bar, the demoulding liquid is more likely to invade the gap between the diverter hole 3 and the aluminum bar, which is convenient for demoulding the aluminum bar remaining in the clamping cavity 9.

[0039] In this embodiment, a plate 31 is fixedly provided on the upper end surface of the bottom support plate 25, and an arc block 32 is fixedly provided between the two plates 31. The curvature of the inner surface of the arc block 32 is consistent with the curvature of the outer surface of the left mold 1; the slide groove is defined by the top cover plate 26 and the plate 31. When in use, the slider 28 on the left mold 1 is placed into the slide groove from above, and the left mold 1 is located in the arc block 32, so that the arc block 32 provides support for the left mold 1.

[0040] In this embodiment, an extrusion groove 33 is formed on the left side surface of the left mold 1 , and the left end of each diversion hole 3 is formed on the inner bottom wall of the extrusion groove 33 .

[0041] In this embodiment, a driving surface 34 is provided at the end of each locking rod 8. When the locking rod 8 enters the locking cavity 9, the driving surface 34 of the locking rod 8 cooperates with the inclined surface 16 of the locking head 13, making it easier to drive the locking head 13 to move into the accommodating groove 14.

[0042] The implementation principle of one embodiment of the present application is as follows: when in use, the slider 28 on the left mold 1 is placed into the slide groove from the notch 30, and then the right mold 2 is slid from the right side into the slide groove between the bottom support plate 25 and the top cover plate 26, and each locking rod 8 is inserted into the corresponding locking cavity 9 of the left mold 1, and then the pin is inserted into the pin hole 27 of the top cover plate 26 and the insertion hole 29 of the slider 28 on the right mold 2 to fix the right mold 2; after being heated, the aluminum profile bar is pushed by an external force and forced into from the left side of the left mold 1, the aluminum profile bar is diverted, and the metal of the aluminum profile bar flows into each diversion hole 3, and the metal further squeezes the extrusion plate 11, so that the locking head 13 is pushed into the locking groove 17 more tightly, and the diversion hole 3 guides the metal of the aluminum profile bar to the surrounding of the mold core 4; the metal entering the welding chamber 5 of the right mold 2 is welded together from the mold core 4 and the forming hole 6 is extruded into the forming cavity to form a formed aluminum profile. The metal generates a rightward thrust on the right mold 2, so that the clamping rod 8 moves rightward to extrude the clamping head 13 downward. However, the metal in the diverter hole 3 extrude the extrusion plate 11, preventing the clamping head 13 from moving inward. After the fixing frame 7 fixes the left mold 1 and the right mold 2, the purpose of self-locking of the left mold 1 and the right mold 2 is further achieved, ensuring that no gap is generated between the left mold 1 and the right mold 2 during use, ensuring the quality of aluminum profile processing, and reducing the defective rate; the heat of the metal in the diverter hole 3 is transferred to the extrusion plate 11, the locking rod 12 and the clamping head 13 in turn, and the heat on the clamping head 13 is dissipated into the center hole 18 through the clamping rod 8. The heat in the center hole 18 escapes to the outside through the air vents 19 and the heat dissipation holes 20, thereby achieving the purpose of effective heat dissipation inside the mold.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
