Description

Technical Field

[0001] The present invention belongs to the technical field of powder metallurgy, and particularly relates to a lateral core-pulling device for powder metallurgy. Background Art

[0002] A lateral core-pulling device for powder metallurgy is a device specifically used for lateral parting and core-pulling operations in powder metallurgy molds. During the powder metallurgy forming process, due to the characteristics of some products such as lateral holes or concave-convex shapes on the side walls, traditional axial core-pulling cannot meet the requirements. Therefore, a lateral core-pulling device is needed to complete the forming and demolding of such products. Through specific mechanism design, the parts (i.e., lateral core) forming the lateral holes or side recesses can be withdrawn from the mold before the mold is opened, thereby ensuring that the product can be smoothly demolded and maintaining its integrity and precision.

[0003] The traditional structure controls the opening and closing of the mold through hydraulic or mechanical drive, uses inclined guide posts or oil cylinders to drive the core-pulling assembly to move horizontally to complete lateral parting, and then longitudinally pushes out the plastic part through ejector rods or ejector plates. It is difficult to dynamically adapt to the real-time deformation during the plastic part forming process, and it is easy to cause uneven stress on the plastic part during demolding due to uncoordinated actions, resulting in surface scratches, shrinkage marks or structural damage.

Detailed implementation mode

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation mode.

[0022] As Figures 1 to 9 shown, the present invention provides a technical solution: a lateral core-pulling device for powder metallurgy, including a workbench 1, a metallurgical table 2 is fixedly installed on the top of the workbench 1, two half-side molds 3 are symmetrically arranged at the center position of the metallurgical table 2, and when the two half-side molds 3 are combined together, they can form a complete mold. A core part 4 is inserted into the inner wall between the two half-side molds 3. Separation components are arranged on both sides of the two half-side molds 3, and the separation components enable the two half-side molds 3 to move away from or close to each other. A core-pulling component is arranged on one side of the core part 4, and the core-pulling component is used to pull the core part 4 out of the side of the plastic part. A lifting component is arranged on one side of the core-pulling component, and the lifting component is used to lift the position of the core part 4.

[0023] During operation: In the initial state, the two half molds 3 are tightly combined together to form a complete mold, and the core part 4 is horizontally located in the middle of the two half molds 3, and it horizontally penetrates between the inner walls of the two half molds 3. After uniformly filling the powder into the inner walls of the two half molds 3, a press is used to compact the powder in the mold to form a preform with a certain density and strength. During the compaction process, the pressure, temperature, and compaction time are controlled to manufacture a complete shaped part. The plastic part formed in the above process is in the shape of a cube. And due to the limitation of the core part 4 at the middle position of the plastic part, a concave cylindrical groove will appear at the middle position of the cube-shaped plastic part. Therefore, only after the core part 4 is withdrawn laterally can the entire plastic part be completely taken out; during the process of forming the plastic part, the separating component causes the two half molds 3 to be subjected to a force approaching each other, and the two half molds 3 can be tightly fitted together, effectively preventing the powder from leaking out from the mold gap during the filling process. When the plastic part is completed, the separating component causes the two half molds 3 to move away from each other. After the two half molds 3 move away, the plastic part can be exposed on the upper surface of the metallurgical table 2. At this time, the core part 4 is still inserted into the inner wall of the plastic part. When the two half molds 3 continue to move away from each other, the core part 4 will be withdrawn laterally from the plastic part through the core-pulling component. Since there is a concave cylindrical groove formed by the limitation of the core part 4 at the middle position of the plastic part, if the plastic part is directly taken out of the mold, it will be hindered. Therefore, by laterally withdrawing the core part 4 from the plastic part, the complete removal of the plastic part can be ensured and damage can be avoided. And after the core part 4 is withdrawn, it will move upward a certain distance in the longitudinal direction under the action of the lifting component. When the two half molds 3 are recombined, the core part 4 after upward movement can abut against the outer wall of the plastic part. At this time, the core part 4 is not inserted into the side hole, but pushes the outer wall of the plastic part to push the already cast plastic part out of the upper part of the metallurgical table 2 for collection. Through the above embodiments, the separating component controls the opening and closing of the mold, the core-pulling component moves the core part laterally, and the lifting component pushes the part longitudinally, forming a closed-loop action chain, ensuring that the surface quality of the plastic part is not damaged while improving the working process efficiency of the production line.

[0024] As Figures 2 to 3 shown, the separating component includes two clamping parts 5. The two clamping parts 5 are fixedly installed on the outer wall of the half mold 3. One side of each clamping part 5 is fixedly connected with a moving block 6. Limiting grooves 7 are symmetrically formed on the surface of the metallurgical table 2. The moving block 6 is slidably connected with the limiting groove 7 and is mutually adapted. A driving component for driving the moving block 6 to move is arranged below the moving block 6.

[0025] During operation: When filling powder between the two half molds 3, the driving assembly applies a force that makes the two moving blocks 6 approach each other, and acts on the outer walls of the two half molds 3 through the clamping members 5. After the plastic part casting is completed, the driving assembly drives the two moving blocks 6 to move along the limiting grooves 7. During the movement, the distance between the two moving blocks 6 gradually increases, and the two half molds 3 are pulled apart through the two clamping members 5, so that the two half molds 3 are separated from the plastic part. Moreover, under the restriction of the core part 4, the plastic part will not adhere to the inner wall of the half mold 3 and move together with the half mold 3, thus realizing the mold opening process and not damaging the shape of the plastic part.

[0026] As Figures 2 to 3 shown, the driving assembly includes a fixed seat 9, which is fixedly installed on the top of the workbench 1. A bidirectional threaded block 10 is rotatably connected to the inner wall of the fixed seat 9. Inner threaded blocks 8 are symmetrically threadedly connected to the outer wall of the bidirectional threaded block 10. The tops of the two inner threaded blocks 8 are respectively fixedly connected to the bottoms of the two moving blocks 6. Both of the two inner threaded blocks 8 are slidably connected to the inner wall of the fixed seat 9. A motor 11 is fixedly installed on the top of the workbench 1. A transmission ring 12 is fixedly connected to the output shaft of the motor 11 and one end of the bidirectional threaded block 10 respectively. A transmission belt 13 is drivingly connected between the outer walls of the two transmission rings 12.

[0027] During operation: Start the motor 11, and its output shaft will drive the bidirectional threaded block 10 to rotate through the transmission ring 12 and the transmission belt 13. When the bidirectional threaded block 10 rotates, it will drive the two inner threaded blocks 8 to move along the inner wall of the fixed seat 9. Since the thread directions on both sides of the bidirectional threaded block 10 are opposite, when the two inner threaded blocks 8 move, they will only approach or move away from each other. When the two inner threaded blocks 8 move, they will make the two half molds 3 complete the mold closing and mold opening processes through the moving blocks 6 and the clamping members 5, so as to quickly take out the plastic part. The taken-out plastic part will remain at the central position of the metallurgical table 2.

[0028] As Figures 4 to 6 shown, the core pulling assembly includes an installation sliding seat 18, which is fixedly installed on the top of the workbench 1. An inner sliding block 17 is slidably connected to the inner wall of the installation sliding seat 18. A core pulling part 20 is arranged on the top of the inner sliding block 17. The core pulling part 20 is fixedly connected to the outer wall of one end of the core part 4. Connecting rods 16 are fixedly connected to both sides of the inner sliding block 17. A pushing assembly is arranged above the connecting rods 16. The pushing assembly makes the inner sliding block 17 slide along the inner wall of the installation sliding seat 18 through the connecting rods 16.

[0029] During operation: When the driving component causes the two moving blocks 6 to completely separate the two half molds 3, when the two moving blocks 6 continue to move, the inner slider 17 will slide along the inner wall of the mounting slide 18 through the pushing component. When the two inner sliders 17 move, they will drive the core component 4 to move through the core pulling component 20. When the core component 4 moves, it will gradually be withdrawn from the inner wall of the plastic part, thus achieving a separated state from the plastic part, and thus realizing the effect of lateral core pulling.

[0030] As Figures 4 to 5 shown, the pushing component includes two extrusion platforms 15. One side of each of the two moving blocks 6 is fixedly connected with a connecting block 14. The two connecting blocks 14 are respectively slidably connected between the two extrusion platforms 15. The bottom parts of the two connecting rods 16 are respectively fixedly connected with the bottom parts of the two extrusion platforms 15. The extrusion platform 15 is composed of two sections, one section is straight and the other section is inclined.

[0031] During operation: When the two moving blocks 6 move, they will first cause the connecting block 14 to slide along the inner wall of the straight section of the extrusion platform 15. At this time, the two half molds 3 are separated from each other, and the plastic part is completely exposed on the upper surface of the metallurgical table 2. When the two moving blocks 6 continue to move, the connecting block 14 will move along the inner wall of the inclined section of the extrusion platform 15. At this time, when the connecting block 14 continues to move, it will squeeze the extrusion platform 15 to move outward. The extrusion platform 15 will drive the inner slider 17 to move along the inner wall of the mounting slide 18 through the connecting rod 16. Therefore, the inner slider 17 will cause the core component 4 to be pulled out laterally from the plastic part through the core pulling component 20.

[0032] As Figures 7 to 9 shown, the lifting component includes two outer square plates 23. One side of the two outer square plates 23 is fixedly connected with a mounting frame 35. The mounting frame 35 is symmetrically and fixedly installed on the side surface of the workbench 1. The outer wall of the outer square plate 23 is fixedly connected with a plurality of connecting pieces 28. The outer wall of the connecting piece 28 is fixedly connected with an inner square plate 24. A sliding groove one 25, a side sliding groove 27 and a sliding groove two 26 are formed between the outer square plate 23 and the inner square plate 24. Both sides of the core pulling component 20 are fixedly connected with fixing rods 21. The outer walls of the fixing rods 21 are fixedly connected with sliding blocks 22. The sliding blocks 22 can slide along the inner walls of the sliding groove one 25, the side sliding groove 27 and the sliding groove two 26.

[0033] During operation: when the core puller 20 drives the core piece 4 to be pulled out from the inner wall of the plastic part, the core puller 20 will slide along the inner wall of the sliding groove 1 25 through the sliding block 22. During the sliding process, the core puller 20 always maintains a lateral moving direction, so that the core piece 4 and the plastic part always maintain a vertical relationship when separated, to avoid the core piece 4 shaking when being pulled out and causing damage to the plastic part, and when the sliding block 22 moves one end of the sliding groove 1 25, the core piece 4 is completely pulled out, at this time the sliding block 22 will slide upward along the inner wall of the side sliding groove 27, and enter the inner wall of the sliding groove 2 26 through the side sliding groove 27; when the two half-side molds 3 are reset by the separation assembly, the two sliding blocks 22 will slide in the opposite direction and reset under the action of the pushing assembly, at this time the connecting block 14 will first tilt along the extrusion table 15 The movement of the oblique inner wall causes the sliding block 22 to slide along the inner wall of the second sliding groove 26. At this time, one end of the core piece 4 will gradually press against the outer wall of the plastic part, offset the position of the slot formed by the plastic part, and push the plastic part out of the upper surface of the metallurgical table 2, thereby achieving the effect of taking out the plastic part. When the plastic part is completely pushed out, the sliding block 22 will move to one end of the second sliding groove 26. When the sliding block 22 moves to one end of the second sliding groove 26, it slides downward to one end of the inner wall of the first sliding groove 25 through the side sliding groove 27 again, thereby returning to the initial position. When the two half-side molds 3 continue to move closer to reset, the connecting block 14 slides along the straight inner wall of the extrusion table 15 again, wrapping the core piece 4 in the inner walls of the two half-side molds 3, thereby forming a complete mold and core piece in the initial state.

[0034] like Figures 8 to 9 As shown, one end of the fixing rod 21 is fixedly connected with a magnet 1 29, the top of the outer square plate 23 is fixedly installed with a fixing frame 30, the bottom of the fixing frame 30 is fixedly connected with a magnet 2 31 and a magnet 3 32, the magnet 2 31 and the magnet 1 29 are longitudinally parallel, and the magnet 2 31 and the magnet 3 32 are transversely parallel.

[0035] During operation: when the sliding block 22 slides along the inner wall of the sliding groove 1 25 to the end close to the magnet 32, the magnet 1 29 will, under the action of the magnet 32, make the sliding block 22 slide upward along the inner wall of the side sliding groove 27, so that the sliding block 22 enters the inner wall of one end of the sliding groove 26, and after the core piece 4 is completely pulled out, it will be lifted upward for a distance. When resetting, the core piece 4 will slide along the inner wall of the sliding groove 26 and push it out against the outer wall of the plastic part. When the sliding block 22 slides along the inner wall of the sliding groove 26 to the end close to the magnet 2 31, the magnet 1 29 will, under the action of the magnet 2 31, make the sliding block 22 slide downward along the inner wall of the side sliding groove 27, so that the sliding block 22 re-enters one end of the inner wall of the sliding groove 1 25, waiting for the two half-side molds 3 to continue to move closer to each other and merge to wrap the core piece 4.

[0036] likeFigures 8 to 9 As shown, the top surface of magnet 1 (29) and the bottom surface of magnet 2 (31) are of the same magnetic pole, while the top surface of magnet 1 (29) and the bottom surface of magnet 3 (32) are of opposite magnetic poles.

[0037] During operation: When the slider (22) slides along the inner wall of the first sliding groove (25) for core pulling, magnet 1 (29) and magnet 3 (32) gradually become longitudinally parallel. Since the top surface of magnet 1 (29) and the bottom surface of magnet 3 (32) are of opposite magnetic poles, magnet 3 (32) can attract the slider (22) into the inner wall of the side sliding groove (27) and slide to one end of the second sliding groove (26). When the slider (22) slides along the inner wall of the second sliding groove (26) to eject the plastic part, magnet 1 (29) and magnet 2 (31) gradually become longitudinally parallel. At this time, since the top surface of magnet 1 (29) and the bottom surface of magnet 2 (31) are of the same magnetic pole, it will repel magnet 1 (29) so that it enters the inner wall of the side sliding groove (27) and slides to one end of the first sliding groove (25).

[0038] As Figures 5 to 7 shown, a first spring (19) is fixedly connected between the inner slider (17) and the core pulling member (20). A second spring (33) is arranged inside the mounting slide (18). One end of the second spring (33) is fixedly connected to one side of the inner slider (17), and the other end of the second spring (33) away from the inner slider (17) is fixedly connected to the inner wall of the mounting slide (18).

[0039] During operation: By providing the first spring (19), it can be used as a medium for the core member (4) to move up and down. When the slider (22) enters the inner wall of the second sliding groove (26) through the side sliding groove (27), magnet 1 (29) will be stretched. When the slider (22) enters the inner wall of the first sliding groove (25) through the side sliding groove (27), magnet 1 (29) will be compressed. And by providing the second spring (33), when the two half-side molds (3) move closer to each other, the inner slider (17) can slide reversely and reset under the action of the second spring (33).

[0040] As Figures 1 to 2 shown, an inclined sliding table (34) is fixedly connected to the side of the metallurgical table (2), and the bottom of the inclined sliding table (34) is fixedly connected to the top of the workbench (1).

[0041] During operation: By providing the inclined sliding table (34), when the plastic part is pushed out along the outer wall by the core member (4), it will slide down along the slope surface of the inclined sliding table (34) and leave the upper surface of the metallurgical table (2) for collection.
