Description

Technical Field

[0001] The present invention relates to the technical field of profile processing, and particularly relates to a die for extruding liquid-cooled motor housing aluminum profiles for new energy vehicles. Background Art

[0002] In the extrusion processing of liquid-cooled motor housing aluminum profiles for new energy vehicles, in order to facilitate the cleaning of residual aluminum chips and waste in the die cavity, traditional dies usually adopt a split structure of upper and lower dies connected by bolts. When assembling such dies, it mainly relies on manual alignment of the runner. After adjusting the position of the positioning pins and completing the positioning, multiple bolts are then used for fixation to achieve the assembly of the upper and lower dies. However, during the actual operation, when fixing multiple bolts, it may cause bumps, shaking, and vibration to the die, resulting in the displacement of the upper and lower dies or insufficient tightness at the connection, leading to misalignment of the runner, resulting in dimensional deviation or surface defects of the profiles, and it is difficult to meet the high requirements for assembly accuracy of the complex runner of the liquid-cooled motor housing, affecting the actual product processing quality and cost.

[0003] In view of this, we propose a die for extruding liquid-cooled motor housing aluminum profiles for new energy vehicles. Summary of the Invention

[0004] Aiming at the above-mentioned drawbacks of the prior art, the present invention provides a die for extruding liquid-cooled motor housing aluminum profiles for new energy vehicles, which can effectively solve the problems that the split die connected by bolts in the prior art is prone to die offset, loose connection, and runner misalignment due to the adjustment of positioning pins and the fixation of multiple bolts during manual assembly, making it difficult to meet the assembly accuracy requirements of complex runners, affecting product quality and increasing costs.

[0005] To achieve the above purposes, the present invention is realized through the following technical solutions:

[0006] The present invention provides a die for extruding liquid-cooled motor housing aluminum profiles for new energy vehicles, including a main body unit, including an upper die, a lower die provided on one side of the upper die, and a first positioning component provided between the upper die and the lower die;

[0007] A plugging unit, including a plugging component provided between the upper die and the lower die, and a reset component provided inside the upper die for resetting the plugging component;

[0008] A fixing unit, including fixing rods provided inside the upper die and the lower die, a second positioning component provided at one end of the fixing rod, a pushing and pulling component provided on the fixing rod for driving the reset component to move, and a connecting component provided at the end of the fixing rod away from the second positioning component for fixing the upper die and the lower die.

[0009] Further, the positioning component I includes a strip-shaped groove formed on the surface of the upper mold. A convex strip is inserted into the interior of the strip-shaped groove, and one end of the convex strip away from the upper mold is fixedly connected to one side of the lower mold close to the upper mold.

[0010] Further, the plugging component includes a groove II formed inside the upper mold. A convex block II is inserted into the interior of the groove II, and insertion holes are formed at both the top and bottom of the convex block II.

[0011] Further, an insertion rod is inserted into the interior of the insertion hole. One end of the insertion rod away from the convex block II is fixedly connected to a spring, and the other end of the spring is fixedly connected to the inner wall of the upper mold. One end of the insertion rod away from the convex block II is also fixedly connected to a connecting rod for connecting the reset component.

[0012] Further, the reset component includes a trapezoidal block II fixedly connected to one end of the connecting rod away from the insertion rod. A trapezoidal block I is correspondingly arranged on one side of the trapezoidal block II. One side of the trapezoidal block I away from the trapezoidal block II is fixedly connected to a sliding rod, and the sliding rod is slidably matched with the inner wall of the upper mold through a chute formed on the surface.

[0013] Further, the bottom of the sliding rod is fixedly connected to a collar sleeved on the inner wall of the upper mold, and a through groove II corresponding to the pushing and pulling component is formed on the inner wall of the collar.

[0014] Further, the positioning component II includes a plum blossom plate fixedly connected to one end of a fixed rod. A groove I is formed on the surface of the plum blossom plate. A convex block I corresponding to the groove I is arranged on one side of the plum blossom plate, and the convex block I is fixedly connected to the inner wall of the lower mold.

[0015] Further, the connecting component includes a threaded hole formed inside the upper mold. A screw rod is threadedly connected to the inner wall of the threaded hole, and one end of the screw rod is fixedly connected to one end of the fixed rod away from the plum blossom plate.

[0017] The technical solution provided by the present invention has the following beneficial effects compared with the known public technology:

[0018] Through the rough positioning of the strip-shaped groove and the convex strip and the automatic clamping structure of the insertion rod and the insertion hole, the present invention does not require manual repeated adjustment of the positioning pin. The rapid and precise alignment of the upper and lower mold runners is realized through mechanical linkage, which can avoid the position deviation caused by the shaking during the fixing process by the screw rod. Through the multi-dimensional constraint system, the assembly accuracy can be improved, the forming consistency of the complex runner can be improved, and the production and processing quality of the liquid-cooled motor housing for new energy vehicles can be enhanced;

[0019] During disassembly, the plug-in components are automatically separated through a sequential unlocking mechanism, avoiding the collision and wear of the mold and related components during manual disassembly, making disassembly and assembly more convenient.

[0031] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] The present invention will be further described below with reference to the embodiments.

[0033] A die for extruding an aluminum profile of a liquid-cooled motor housing for a new energy vehicle, including a main body unit 100, including an upper die 101, a lower die 102 provided on one side of the upper die 101, and a first positioning component 103 provided between the upper die 101 and the lower die 102, a plug-in unit 300, including a plug-in component 302 provided between the upper die 101 and the lower die 102, and a reset component 301 provided inside the upper die 101 for resetting the plug-in component 302, a fixing unit 200, including fixing rods 202 provided inside the upper die 101 and the lower die 102, a second positioning component 201 provided at one end of the fixing rod 202, a push-pull component 203 provided on the fixing rod 202 for driving the reset component 301 to move, and a connecting component 204 provided at the end of the fixing rod 202 away from the second positioning component 201 for fixing the upper die 101 and the lower die 102;

[0034] Specifically, the first positioning component 103 includes a strip-shaped groove 1031 opened on the surface of the upper die 101, a convex strip 1032 is inserted inside the strip-shaped groove 1031, and one end of the convex strip 1032 away from the upper die 101 is fixedly connected to the side of the lower die 102 close to the upper die 101;

[0035] It should be noted that the upper die 101 mainly includes shunt holes and diversion grooves, which are responsible for shunting the aluminum rod into multiple metal streams to match the multi-branch structure of the liquid-cooling runner. The lower die 102 includes a die core, forms a runner inner cavity, and the die sleeve fixes the die core and bears the extrusion pressure, as well as a working belt, which is used to control the dimensional accuracy of the profile, so as to realize the extrusion processing and forming of the liquid-cooled motor housing. Before processing, the upper die 101 and the lower die 102 need to be assembled. During assembly, the rib 1032 of the lower die 102 can be aligned with the strip groove 1031 of the upper die 101, and the rib 1032 is inserted into the strip groove 1031 to realize the positioning of the assembly of the upper die 101 and the lower die 102 and avoid the dislocation of the internal runner;

[0036] Furthermore, the plug-in assembly 302 includes a second groove 3024 opened inside the upper die 101. A second convex block 3025 is inserted inside the second groove 3024. Jacks 3026 are opened at the top and bottom of the second convex block 3025. A plug rod 3021 is inserted inside the jack 3026. One end of the plug rod 3021 away from the second convex block 3025 is fixedly connected to a spring 3023, and the other end of the spring 3023 is fixedly connected to the inner wall of the upper die 101. One end of the plug rod 3021 away from the second convex block 3025 is also fixedly connected to a connecting rod 3022 for connecting the reset assembly 301. The reset assembly 301 includes a second trapezoidal block 3013 fixedly connected to one end of the connecting rod 3022 away from the plug rod 3021. A first trapezoidal block 3012 is correspondingly arranged on one side of the second trapezoidal block 3013. One side of the first trapezoidal block 3012 away from the second trapezoidal block 3013 is fixedly connected to a sliding rod 3011, and the sliding rod 3011 is slidably matched with the inner wall of the upper die 101 through a chute opened on the surface. The bottom of the sliding rod 3011 is fixedly connected to a collar 3014 sleeved on the inner wall of the upper die 101. A second through groove 3015 corresponding to the pushing and pulling assembly 203 is opened on the inner wall of the collar 3014;

[0037] It should be noted that when the rib 1032 of the lower die 102 is inserted into the strip groove 1031 of the upper die 101, the second convex block 3025 can be directly inserted into the second groove 3024. At this time, the two plug rods 3021 are first squeezed by the second convex block 3025, so that the spring 3023 is compressed, and the plug rod 3021 and the connecting rod 3022 move away from the second convex block 3025. When the rib 1032 is completely inserted into the strip groove 1031, at this time, the second convex block 3025 is also exactly completely inserted into the second groove 3024. Since the jack 3026 is opened on the second convex block 3025, by using the elastic action of the spring 3023, the plug rod 3021 can be driven to reset, so that the plug rod 3021 is inserted into the jack 3026, which can avoid the dislocation and deviation of the positions between the upper die 101 and the lower die 102 when the upper die 101 and the lower die 102 are connected and fixed by using the connecting assembly 204;

[0038] When it is necessary to disassemble the upper die 101 and the lower die 102, first disassemble the connecting component 204. When disassembling the connecting component 204, the push-pull component 203 on the fixing rod 202 can drive the collar 3014 to move towards the lower die 102, so as to drive the two groups of trapezoidal blocks 3012 to move towards the trapezoidal block 3013 through the sliding rod 3011. At this time, the trapezoidal block 3013 is squeezed by the trapezoidal block 3012, and can drive the plug 3021 connected to the connecting rod 3022 to move away from the convex block 3025. At this time, the spring 3023 is compressed, and the plug 3021 completely disengages from the jack 3026, and the upper die 101 and the lower die 102 can be directly disassembled and separated;

[0039] Furthermore, the positioning component 201 includes a plum blossom plate 2011 fixedly connected to one end of the fixing rod 202. A first groove 2012 is formed on the surface of the plum blossom plate 2011. A first convex block 2013 corresponding to the first groove 2012 is arranged on one side of the plum blossom plate 2011. The first convex block 2013 is fixedly connected to the inner wall of the lower die 102. The connecting component 204 includes a threaded hole 2042 formed inside the upper die 101. A screw 2041 is threadedly connected to the inner wall of the threaded hole 2042. One end of the screw 2041 is fixedly connected to the end of the fixing rod 202 away from the plum blossom plate 2011. The push-pull component 203 includes two limiting rings 2031 fixedly connected to the surface of the fixing rod 202. The surfaces of the two limiting rings 2031 are slidably connected to the inner wall of the second through groove 3015, and through grooves 2032 slidably matched with the collar 3014 are formed on the surfaces of the two limiting rings 2031;

[0040] It should be noted that when assembling the upper die 101 and the lower die 102, the positioning and snap-fixing between the upper die 101 and the lower die 102 are realized through the plugging component 302 and the first positioning component 103, ensuring the relative fixation of the positions between the upper die 101 and the lower die 102. Then, the first groove 2012 of the plum blossom disc 2011 can be aligned with the first convex block 2013 on the lower die 102, and the fixing rod 202 and the connecting component 204 are plugged into the upper die 101 and the lower die 102. When the end of the screw rod 2041 far from the fixing rod 202 just touches the threaded hole 2042, at this time, the first through groove 2032 of the limit ring 2031 just slidably cooperates with the collar 3014, and the second through groove 3015 of the collar 3014 just slidably cooperates with the limit ring 2031. At this time, a plum blossom screwdriver can be inserted into the plum blossom disc 2011, and the plum blossom disc 2011 is rotated, thereby driving the fixing rod 202 to rotate, and making the screw rod 2041 threadedly connected to the threaded hole 2042, realizing the fixation between the upper die 101 and the lower die 102. And because the limit ring 2031 rotates with the fixing rod 202 at this time, the limit ring 2031 slides in the second through groove 3015. Because the limit ring 2031 rotates and axially moves at the same time, the first through groove 2032 cannot be aligned with the collar 3014, realizing axial sliding. Therefore, at the same time, the limit ring 2031 can drive the collar 3014 and related components to move away from the lower die 102;

[0041] It should be noted that when the upper die 101 and the lower die 102 are separated and not assembled, at this time, the fixing rod 202 and related components have not been inserted into the upper die 101 and the lower die 102. At this time, through the elastic action of the spring 3023 inside the upper die 101, the plug rod 3021 can be moved back to its original position, thereby driving the second trapezoidal block 3013 to move, and the first trapezoidal block 3012 and the slide rod 3011 fixing the first trapezoidal block 3012 can be pushed away from the second trapezoidal block 3013, without affecting the normal plugging cooperation of the plugging component 302;

[0042] When the upper die 101 and the lower die 102 are disassembled, during assembly, the through slot 2032 on the limit ring 2031 and the collar 3014 are misaligned. Then, by reversely turning the plum blossom plate 2011 with a plum blossom screwdriver, the screw rod 2041 can be disengaged from the threaded hole 2042. At this time, while the fixed rod 202 drives the limit ring 2031 to rotate, it can drive the collar 3014 to move axially synchronously, and then drive the trapezoidal block 3012 on the slide rod 3011 to move towards the trapezoidal block 3013, so as to use the trapezoidal block 3012 to squeeze the trapezoidal block 3013, realizing the disengagement of the insertion rod 3021 from the insertion hole 3026. When the screw rod 2041 has not completely disengaged from the threaded hole 2042, the insertion rod 3021 has already completely disengaged from the insertion hole 3026. At this time, the lower die 102 can be moved a short distance away from the upper die 101 to realize the misalignment between the insertion hole 3026 and the insertion rod 3021. At this time, when the plum blossom plate 2011 is rotated again, the screw rod 2041 can be completely disengaged from the threaded hole 2042. When completely disengaged, the through slot 2032 is exactly aligned with the collar 3014. Through the plum blossom plate 2011, the fixed rod 202 and related components can be pulled out from the inside of the upper die 101 and the lower die 102, so as to realize the complete disassembly and separation between the upper die 101 and the lower die 102. And by checking whether the first groove 2012 is aligned with the first protrusion 2013, it can be judged whether the through slot 2032 is aligned with the collar 3014, so as to pull out the fixed rod 202 and related components.

[0043] Working principle of the present invention: The upper die 101 and the lower die 102 need to be initially aligned through the positioning component 103 of the main body unit 100. First, the rib 1032 of the lower die 102 is aligned with the strip groove 1031 of the upper die 101 and inserted horizontally. The cooperation between the rib 1032 and the strip groove 1031 restricts the lateral offset of the upper and lower dies 102, realizing rough positioning and avoiding misalignment of the internal flow channels.

[0044] After rough positioning is completed, the insertion component 302 of the insertion unit 300 starts to automatically clamp. The second protrusion 3025 of the lower die 102 is inserted into the second groove 3024 of the upper die 101. The second protrusion 3025 squeezes the insertion rod 3021 and compresses the spring 3023, so that the insertion rod 3021 drives the connecting rod 3022 to move backward. When the second protrusion 3025 is completely inserted into the second groove 3024, the insertion hole 3026 is aligned with the insertion rod 3021, and the spring 3023 resets and pushes the insertion rod 3021 to insert into the insertion hole 3026, locking the relative positions of the upper and lower dies 102.

[0045] Then, secondary locking and power transmission are achieved through the fixing unit 200. First, the plum blossom disk 2011 at one end of the fixing rod 202 is aligned with the protrusion 2013 of the lower mold 102, so that the groove 2012 is engaged with the protrusion 2013, and the plum blossom disk 2011 is rotated, such as using a plum blossom screwdriver, to drive the fixing rod 202 to rotate, so that the screw 2041 is screwed into the threaded hole 2042 of the upper mold 101. When the fixing rod 202 rotates, the limit ring 2031 on its surface slides in the through groove 2 3015 of the ring 3014. At the same time, the through groove 1 2032 of the limit ring 2031 is misaligned with the ring 3014, pushing the ring 3014 to move away from the lower mold 102.

[0046] The diversion holes and guide grooves of the upper die 101 divert the aluminum bar blank into multiple metal flows, matching the porous flow channel structure of the liquid-cooled motor housing. The diverted metal flows enter the core area of the lower die 102, and the profile size accuracy is controlled by the working belt, and finally an aluminum profile with a liquid-cooled flow channel is extruded;

[0047] The plug rod 3021 and the plug hole 3026 of the plug assembly 302, the convex strip 1032 and the strip groove 1031 of the positioning assembly 103, together limit the relative displacement of the upper and lower molds 102 to avoid deformation or misalignment of the flow channel due to pressure.

[0048] When the upper mold 101 and the lower mold 102 need to be disassembled, the plum blossom disk 2011 is rotated in the opposite direction to make the screw rod 2041 withdraw from the threaded hole 2042, and the fixed rod 202 drives the limit ring 2031 to rotate in the opposite direction. At this time, the fixed rod 202 drives the limit ring 2031 to rotate, and can drive the collar 3014 to move axially synchronously, thereby driving the trapezoidal block 1 3012 on the slide bar 3011 to move in the direction of the trapezoidal block 2 3013, so that the trapezoidal block 1 3012 is used to squeeze the trapezoidal block 2 3013, so that the insertion rod 3021 is separated from the insertion hole 3026;

[0049] When the screw rod 2041 has not yet completely disengaged from the threaded hole 2042, the insertion rod 3021 has completely disengaged from the insertion hole 3026. At this time, the lower mold 102 can be moved a short distance away from the upper mold 101 to achieve the misalignment between the insertion hole 3026 and the insertion rod 3021. At this time, the plum blossom disk 2011 can be rotated again to allow the screw rod 2041 to completely disengage from the threaded hole 2042. When completely disengaged, the through groove 1 2032 is aligned with the ring 3014. The plum blossom disk 2011 can be used to pull the fixing rod 202 and related components out of the upper mold 101 and the lower mold 102, thereby achieving complete disassembly and separation between the upper mold 101 and the lower mold 102. By checking whether the groove 1 2012 is aligned with the protrusion 1 2013, it can be judged whether the through groove 1 2032 is aligned with the ring 3014, so that the fixing rod 202 and related components can be pulled out.
