Description

Technical Field

[0001] This invention belongs to the field of powder metallurgy technology: specifically, it relates to a side-pulling core-pulling device for powder metallurgy. Background Technology

[0002] Side-pulling equipment for powder metallurgy is a specialized device for side parting and core pulling operations in powder metallurgy molds. During the powder metallurgy forming process, some products have features such as side holes or concave and convex sidewalls, which makes traditional axial core pulling insufficient. Therefore, side-pulling equipment is needed to complete the forming and demolding of such products. Through a specific mechanism design, it is possible to extract the parts with side holes or concave sides (i.e., side cores) from the mold before the mold opens, thereby ensuring that the product can be successfully demolded and maintain its integrity and precision.

[0003] Traditional structures control the opening and closing of the mold through hydraulic or mechanical drives, and use inclined guide pillars or oil cylinders to drive the core-pulling assembly to move laterally to complete the side parting. Then, the plastic part is pushed out longitudinally by ejector pins or push plates. It is difficult to dynamically adapt to the real-time deformation of the plastic part during the molding process. The uneven force on the plastic part during demolding is easily caused by uncoordinated actions, resulting in surface scratches, shrinkage marks or structural damage.

[0017] 1. The side core-pulling device for powder metallurgy described in this invention, through the driving component, causes two moving blocks to completely separate the two half molds. As the two moving blocks continue to move, they push the component to make the inner slider slide along the inner wall of the mounting slide. When the two inner sliders move, they drive the core to move through the core-pulling component. When the core moves, it is gradually pulled out from the inner wall of the plastic part, thus completing the separation from the plastic part, thereby achieving the effect of side core-pulling.

[0018] 2. The side-pulling core-pulling device for powder metallurgy described in this invention, after the core is pulled out, will move a certain distance vertically upward under the action of the lifting component. After moving upward, the core can press against the outer wall of the plastic part when the two half-molds are re-merged. At this time, the core will not be inserted into the side hole, but will push the outer wall of the plastic part to push the already cast plastic part out of the metallurgical table for collection. The separation component controls the opening and closing of the mold, the core-pulling component moves the core laterally, and the lifting component pushes the core vertically, forming a closed-loop action chain, which ensures that the surface quality of the plastic part is not damaged while improving the workflow efficiency of the production line.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] like Figures 1 to 9 As shown, the present invention provides a technical solution: a side core-pulling device for powder metallurgy, including a worktable 1, a metallurgical table 2 fixedly installed on the top of the worktable 1, two half-molds 3 symmetrically arranged at the center of the metallurgical table 2, the two half-molds 3 can be combined to form a complete mold, a core 4 is inserted into the inner wall between the two half-molds 3, a separation component is provided on both sides of the two half-molds 3, the separation component makes the two half-molds 3 move away from each other or closer, a core-pulling component is provided on one side of the core 4, the core-pulling component is used to pull the core 4 from the side of the plastic part, and a lifting component is provided on one side of the core-pulling component, the lifting component is used to lift the position of the core 4.

[0032] During operation: In the initial state, the two half-molds 3 are tightly joined together to form a complete mold. The core 4 is positioned laterally between the two half-molds 3, and it is inserted laterally between the inner walls of the two half-molds 3. After the powder is evenly filled 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 produce a complete part. The plastic part formed in the above process is a cube shape. Due to the constraint of the core 4 in the middle of the plastic part, a concave cylindrical groove will appear in the middle of the cube plastic part. Therefore, the entire plastic part can only be completely removed after the core 4 is pulled out from the side. During the molding process, the separation component causes the two half-molds 3 to be subjected to a force that brings them closer together. The two half-molds 3 can be tightly fitted together, effectively preventing the powder from leaking out from the mold gaps during the filling process. After the plastic part is completed, the separation component causes the two half-molds 3 to move away from each other. After moving away, the plastic can be exposed on the upper surface of the top of the metallurgical table 2. At this time, the core 4 is still inserted in the inner wall of the plastic part. As the two half-molds 3 continue to move away from each other, the core 4 will be pulled out from the side of the plastic part by the core-pulling assembly. Since there is a concave cylindrical groove in the middle of the plastic part formed by the core 4, it will be obstructed if the plastic part is directly removed from the mold. Therefore, by pulling the core 4 out of the plastic part from the side, the integrity of the plastic part can be ensured and damage can be avoided. After the core 4 is pulled out, it will... Under the action of the lifting component, the core 4 moves a certain distance in the longitudinal position. After moving up, when the two half molds 3 re-merge, the core 4 can press against the outer wall of the plastic part. At this time, the core 4 will not be inserted into the side hole, but will push the outer wall of the plastic part to push the already cast plastic part out of the metallurgical table 2 for collection. Through the above embodiment, the separation component controls the opening and closing of the mold, the core pulling component moves the core laterally, and the lifting component pushes the core longitudinally, forming a closed-loop action chain. This ensures that the surface quality of the plastic part is not damaged while improving the workflow efficiency of the production line.

[0033] like Figures 2 to 3 As shown, the separation component includes two clamping parts 5, which are fixedly installed on the outer wall of the half mold 3. A moving block 6 is fixedly connected to one side of each clamping part 5. Limiting grooves 7 are symmetrically opened on the surface of the metallurgical table 2. The moving block 6 and the limiting groove 7 are slidably connected and adapted to each other. A drive component for moving the moving block 6 is provided below the moving block 6.

[0034] During operation: When filling powder between the two half-molds 3, the drive assembly applies a force to the two moving blocks 6 to bring them closer together, and acts on the outer wall of the two half-molds 3 through the clamping parts 5. After the plastic part is cast, the drive assembly drives the two moving blocks 6 to move along the limiting groove 7. During the movement, the distance between the two moving blocks 6 gradually increases, and the two clamping parts 5 pull the two half-molds 3 apart, thereby separating the two half-molds 3 from the plastic part. 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 with the half-mold 3, thus realizing the mold opening process without damaging the shape of the plastic part.

[0035] like Figures 2 to 3 As shown, the drive assembly includes a fixed base 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 base 9. An internal threaded block 8 is symmetrically threaded to the outer wall of the bidirectional threaded block 10. The tops of the two internal threaded blocks 8 are fixedly connected to the bottoms of the two moving blocks 6 respectively. Both internal threaded blocks 8 are slidably connected to the inner wall of the fixed base 9. A motor 11 is fixedly installed on the top of the workbench 1. A transmission ring 12 is fixedly connected to one end of the bidirectional threaded block 10 and the outer walls of the two transmission rings 12 are connected by a transmission belt 13.

[0036] During operation: When the motor 11 is started, 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 internal threaded blocks 8 to move along the inner wall of the fixed seat 9. Since the threads on both sides of the bidirectional threaded block 10 are opposite, the two internal threaded blocks 8 will only move closer or further away from each other when they move. When the two internal threaded blocks 8 move, they will enable the two half molds 3 to complete the mold closing and opening process through the moving block 6 and the clamping part 5, thereby quickly removing the plastic part. The removed plastic part will be retained at the center of the metallurgical table 2.

[0037] like Figures 4 to 6 As shown, the core-pulling assembly includes a mounting slide 18, which is fixedly mounted on the top of the workbench 1. An inner slider 17 is slidably connected to the inner wall of the mounting slide 18. A core-pulling component 20 is provided on the top of the inner slider 17. The core-pulling component 20 is fixedly connected to the outer wall of one end of the core component 4. Connecting rods 16 are fixedly connected to both sides of the inner slider 17. A pushing component is provided above the connecting rods 16. The pushing component causes the inner slider 17 to slide along the inner wall of the mounting slide 18 through the connecting rods 16.

[0038] During operation: When the drive component causes the two moving blocks 6 to completely separate the two half molds 3, as the two moving blocks 6 continue to move, they will push the component to make the inner slider 17 slide along the inner wall of the mounting slide 18. When the two inner sliders 17 move, they will drive the core part 4 to move through the core pulling component 20. When the core part 4 moves, it will gradually be pulled out from the inner wall of the plastic part, thus completing the separation from the plastic part, thereby achieving the effect of lateral core pulling.

[0039] like Figures 4 to 5 As shown, the pushing assembly includes two extrusion platforms 15, and a connecting block 14 is fixedly connected to one side of each of the two moving blocks 6. The two connecting blocks 14 are slidably connected to the two extrusion platforms 15 respectively. The bottoms of the two connecting rods 16 are fixedly connected to the bottoms of the two extrusion platforms 15 respectively. The extrusion platform 15 is composed of two sections, one of which is straight and the other of which is inclined.

[0040] During operation: When the two moving blocks 6 move, the connecting block 14 will first slide along the straight inner wall of the extrusion table 15. At this time, the two half molds 3 separate from each other, so that 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 inclined inner wall of the extrusion table 15. When the connecting block 14 continues to move, it will squeeze the extrusion table 15 to move outward. The extrusion table 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 use the core-pulling part 20 to pull the core part 4 out from the side of the plastic part.

[0041] like Figures 7 to 9 As shown, the lifting assembly includes two outer square plates 23. A mounting bracket 35 is fixedly connected to one side of each outer square plate 23. The mounting bracket 35 is symmetrically fixedly installed on the side of the workbench 1. Multiple connectors 28 are fixedly connected to the outer wall of the outer square plate 23. An inner square plate 24 is fixedly connected to the outer wall of the connector 28. A sliding groove 1 25, a side sliding groove 27, and a sliding groove 26 are formed between the outer square plate 23 and the inner square plate 24. Fixed rods 21 are fixedly connected to both sides of the core-pulling component 20. Sliding blocks 22 are fixedly connected to the outer wall of each fixed rod 21. The sliding blocks 22 can slide along the inner wall of the sliding groove 1 25, the side sliding groove 27, and the sliding groove 26.

[0042] During operation: When the core-pulling component 20 pulls the core component 4 out from the inner wall of the plastic part, the core-pulling component 20 will slide along the inner wall of the sliding groove 1 25 via the sliding block 22. During the sliding process, the core-pulling component 20 always maintains a lateral movement direction, so that the core component 4 and the plastic part always maintain a perpendicular relationship when separated, avoiding the core component 4 shaking during extraction and causing damage to the plastic part. When the sliding block 22 moves to one end of the sliding groove 1 25, the core component 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 26 through the side sliding groove 27. When the two half molds 3 are reset by the separation component, the two sliding blocks 22 will slide in opposite directions to reset under the action of the pushing component. At this time, the connecting block 14 will first tilt along the extrusion table 15. The movement of the inclined 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 4 will gradually press against the outer wall of the plastic part, offsetting the position of the groove formed by the plastic part, and pushing the plastic part away from the upper surface of the metallurgical table 2, thereby achieving the effect of removing 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 will slide down through the side sliding groove 27 to one end of the inner wall of the first sliding groove 25, thereby returning to the initial position. When the two half molds 3 continue to move closer and reset, the connecting block 14 will slide along the straight inner wall of the extrusion table 15, wrapping the core 4 in the inner wall of the two half molds 3, thereby forming a complete mold and core in the initial state.

[0043] like Figures 8 to 9 As shown, one end of each fixing rod 21 is fixedly connected to a magnet 29. The top of the outer square plate 23 is fixedly installed with a fixing bracket 30. The bottom of the fixing bracket 30 is fixedly connected to a magnet 31 and a magnet 32. The magnet 31 and the magnet 29 are in a longitudinal parallel relationship, and the magnet 31 and the magnet 32 ​​are in a transverse parallel relationship.

[0044] During operation: When the sliding block 22 slides along the inner wall of the sliding groove 25 to the end near the magnet 32, the magnet 29 will cause the sliding block 22 to slide upward along the inner wall of the side sliding groove 27 under the action of the magnet 32, so that the sliding block 22 enters the inner wall of one end of the sliding groove 26. After the core 4 is completely pulled out, it will be lifted upward a certain distance. When the core 4 is reset, it will slide along the inner wall of the sliding groove 26 and push out 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 near the magnet 31, the magnet 29 will cause the sliding block 22 to slide downward along the inner wall of the side sliding groove 27 under the action of the magnet 31, so that the sliding block 22 re-enters the inner wall of the sliding groove 25, waiting for the two half molds 3 to continue to move closer to each other and merge to wrap around the core 4.

[0045] like Figures 8 to 9 As shown, the top surface of magnet 29 and the bottom surface of magnet 31 have the same magnetic poles, while the top surface of magnet 29 and the bottom surface of magnet 32 ​​have opposite magnetic poles.

[0046] During operation: When the sliding block 22 slides along the inner wall of the sliding groove 25 to pull the core, the magnet 29 and the magnet 32 ​​gradually become parallel in the longitudinal direction. Since the top surface of the magnet 29 and the bottom surface of the magnet 32 ​​have opposite magnetic poles, the magnet 32 ​​can attract the sliding block 22 into the inner wall of the side sliding groove 27 and slide to one end of the sliding groove 26. When the sliding block 22 slides along the inner wall of the sliding groove 26 to push out the plastic part, the magnet 29 and the magnet 31 will gradually become parallel in the longitudinal direction. At this time, since the top surface of the magnet 29 and the bottom surface of the magnet 31 have the same magnetic poles, the magnet 29 will be repelled, causing it to enter the inner wall of the side sliding groove 27 and slide to one end of the sliding groove 25.

[0047] like Figures 5 to 7 As shown, a spring 19 is fixedly connected between the inner slider 17 and the core-pulling component 20. A spring 23 is provided inside the mounting slide 18. One end of the spring 23 is fixedly connected to one side of the inner slider 17, and the end of the spring 23 away from the inner slider 17 is fixedly connected to the inner wall of the mounting slide 18.

[0048] During operation: The spring 19 can be used as a medium to lift and lower the core 4. When the sliding block 22 enters the inner wall of the sliding groove 26 through the side sliding groove 27, the magnet 29 will be stretched. When the sliding block 22 enters the inner wall of the sliding groove 25 through the side sliding groove 27, the magnet 29 will be squeezed. And when the two half molds 3 move closer to each other through the spring 33, the inner slider 17 can slide back and reset under the action of the spring 33.

[0049] like Figures 1 to 2 As shown, an inclined slide 34 is fixedly connected to the side of the metallurgical table 2, and the bottom of the inclined slide 34 is fixedly connected to the top of the worktable 1.

[0050] During operation: When the plastic part is pushed out by the core part 4 along the outer wall via the inclined slide 34, it will slide out along the slope of the inclined slide 34 and be collected away from the upper surface of the metallurgical table 2.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
