Description

Technical Field

[0001] This invention relates to the field of copper sleeve casting molds, specifically an energy-saving copper sleeve casting mold. Background Technology

[0002] A copper bushing casting mold is a specialized forming tool used to produce copper bushing parts. It typically consists of a metal cavity, a gating system, and a sand core or core box. Through gravity casting or centrifugal casting processes, molten copper is cooled and solidified within the mold cavity to obtain a copper bushing blank with precise dimensions, dense structure, and high wear resistance.

[0003] A specific energy-saving copper sleeve casting mold, as described in application number CN201920613210.6, includes a lower mold body, which comprises a lower mold block. A groove is formed at the top of the lower mold block, and a mold column is fixedly connected to the bottom of the inner wall of the groove. Fixing slots are formed on the top of the lower mold block and on both sides of the groove. This invention utilizes the interplay of the lower mold body, lower mold block, groove, mold column, fixing slots, first fixing block, first limiting plate, upper mold body, upper mold block, second fixing block, second limiting plate, pressure plate, insert rod, insertion hole, cavity, discharge port, discharge groove, guide tube, and pressure block. The insert rod is inserted into the fixing slot to limit the upper and lower mold bodies. The first and second limiting plates further position the upper and lower mold bodies, significantly improving the stability of the connection between the upper and lower molds and greatly facilitating the casting of copper sleeves. The aforementioned device does not include components for automatic demolding. Since the existing device cannot automatically eject the copper sleeve casting inside the mold for easy demolding after casting and cooling, manual demolding is required by the workers, reducing work efficiency. Therefore, an energy-saving copper sleeve casting mold is proposed to address the above problems. Summary of the Invention

This invention simplifies the operation steps. 3. Through the structural design of the release spraying mechanism, this invention achieves a sealing function, solving the problem that if no sealing component is provided, the release agent is prone to leakage during use, thereby increasing the amount of release agent used and increasing costs, and improving the sealing effect.

The first transmission rod 22 is slidably connected to the guide groove 23. The first transmission rod 22 is a round rod design. The transmission rack 24 is meshed with the first gear 25. The inner wall of the first gear 25 is fixedly connected to the outer side of the one-way bearing 26. The inner wall of the one-way bearing 26 is fixedly connected to the outer side of the left side of the second transmission rod 27. The right side of the second transmission rod 27 passes through the left side of the gear pump outer body 30 and reaches the inside of the gear pump outer body 30. The second transmission rod 27 is rotatably connected to the gear pump outer body 30. The right side of the second transmission rod 27 is fixedly connected to the left side of the second gear 28.The right end of the second gear 28 is fixedly connected to the left end of the first transmission block 29.

The second gear 28 meshes with the third gear 32. The left and right sides of the third gear 32 are also fixedly connected to one end of the second transmission block 33. The other end of the second transmission block 33 is inserted into the inner wall of the gear pump outer body 30, and the second transmission block 33 is rotatably connected to the gear pump outer body 30. The front and rear ends of the right side of the gear pump outer body 30 are also fixedly connected to one end of the first fixing bracket 31. The other end of the first fixing bracket 31 is fixedly connected to the right side of the lower mold body 1. Both the first transmission block 29 and the second transmission block 33 are circular blocks. The bottom end of the pump outer body 30 is fixedly connected to the top end of the third connecting pipe 48. The bottom end of the third connecting pipe 48 passes through the top end of the liquid storage tank 37 and reaches the bottom end of the liquid storage tank 37. The bottom end of the liquid storage tank 37 is fixedly connected to the top end of the second fixing frame 40. The left side end of the second fixing frame 40 is fixedly connected to the right side end of the lower mold body 1. The top end of the liquid storage tank 37 is fixedly connected to the bottom end of the injection pipe 38. A sealing cap 39 is sleeved on the outer side of the top end of the injection pipe 38, and the sealing cap 39 is threadedly connected to the injection pipe 38. The top end of the gear pump outer body 30 is fixedly connected to the bottom end of the first connecting pipe 34. The top end of the first connecting pipe 34 is fixedly connected to the second connecting pipe 35. The front and rear ends of the second connecting pipe 35 are also fixedly connected to nozzles 36. The outer side of the nozzles 36 is fixedly connected to the inner wall of the lower mold body 1. During operation, the upper mold body 2 is closed to the top of the lower mold body 1 for casting. When the upper mold body 2 moves downward, it first contacts the top of the lower pressure rod 21 and continues to move downward. This causes the upper mold body 2 to press the lower pressure rod 21 downward. As the lower pressure rod 21 moves downward, it moves downward along the interior of the lower mold body 1. Simultaneously, the lower pressure rod 21 pushes the lifting plate 10 downward. When the lifting plate 10 moves downward, it drives the moving ejector rod 19 and the moving ejector head 20 to move downward simultaneously. The moving ejector rod 19 moves downward along the interior of the lower mold body 1 until the moving ejector head 20 is fully inserted into the bottom of the lower mold body 1. Similarly, when the lifting plate 10 moves downward... When the lifting plate 10 moves, it will drive the four sets of first fixed seats 11 and first rotating heads 12 at the bottom of the lifting plate 10 to move downwards synchronously. During the movement, the first rotating heads 12 also rotate along the outer side of the first fixed seats 11, thereby driving the moving rod 13 to rotate and move downwards. During the movement, the moving rod 13 will retract along the inside of the rotating sleeve rod 14, driving the rotating sleeve rod 14 to rotate. Simultaneously, the moving rod 13 will compress the first return spring 18 inside the rotating sleeve rod 14, causing it to retract. At the same time, when the rotating sleeve rod 14 rotates, it will drive the second rotating head 15 to rotate along the outer side of the second fixed seat 16. Simultaneously, when the lifting plate 10 moves downwards, it will also drive the first transmission rod 2... 2. Moving along the guide groove 23, and when the first transmission rod 22 moves downward, it will drive the transmission rack 24 to move synchronously. During the movement of the transmission rack 24, it will drive the first gear 25 and the one-way bearing 26 to rotate. The one-way bearing 26 will drive the second transmission rod 27 to rotate. When the transmission rack 24 moves upward, it will also drive the first gear 25 to rotate. However, when the first gear 25 rotates, it can only drive the one-way bearing 26 to rotate and will not drive the second transmission rod 27 to rotate. This prevents the second gear 28 and the third gear 32 from reversing and causing air to be sucked in. At the same time, when the second transmission rod 27 rotates, it will drive the second gear 28 inside the gear pump body 30. When gear 8 rotates, and the second gear 28 rotates, it drives the first transmission block 29 to rotate along the inner wall of the gear pump outer body 30. At the same time, the second gear 28 drives the third gear 32 to rotate, and when the third gear 32 rotates, it will drive the second transmission blocks 33 on both sides to rotate along the inner wall of the gear pump outer body 30. The first fixing bracket 31 on the side end of the gear pump outer body 30 is used to fix and support the position of the gear pump outer body 30. When the second gear 28 and the third gear 32 rotate at the same time, the mold release agent inside the liquid storage tank 37 will be drawn into the gear pump outer body 30 through the third connecting pipe 48. When the mold release agent inside the liquid storage tank 37 needs to be added, it is only necessary to rotate the sealing cap 39 on the outer side of the top of the injection pipe 38.When the sealing cap 39 rotates, it will move upward along the outside of the injection pipe 38 until it is completely detached. Then, the liquid can be filled into the storage tank 37 through the injection pipe 38. The second fixing bracket 40 at the bottom of the storage tank 37 is used to fix and support its position. Simultaneously, the gear pump outer body 30 will deliver the release agent to the nozzle 36 through the first connecting pipe 34 and the second connecting pipe 35. Finally, the release agent is sprayed into the lower mold body 1 through the nozzle 36. Simultaneously, the lower mold body 1 and the upper mold body 2 are completely closed, allowing casting to begin. After casting is complete... After completion, the upper mold body 2 is lifted. When the upper mold body 2 is lifted, the moving top head 20 will release the downward pressure applied to the lower pressure rod 21. Consequently, the first return spring 18 will automatically rebound, pushing the moving rod 13 upward along the inside of the rotating sleeve rod 14. Simultaneously, the moving rod 13 and the rotating sleeve rod 14 will rotate, pushing the lifting plate 10 upward. When the lifting plate 10 moves upward, it will drive the moving top rod 19 and the moving top head 20 upward simultaneously. Thus, the moving top head 20 will lift the casting inside the lower mold body 1, completing the demolding process.

[0021] Example 2: Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 10 As shown, in Comparative Embodiment 1 as another implementation of the present invention, the left end of the gear pump outer body 30 is fixedly connected to the right end of the sealing box 41. The sealing box 41 is sleeved on the outside of the second transmission rod 27, and the sealing box 41 is rotatably connected to the second transmission rod 27. The outside of the second transmission rod 27 is fixedly connected to the inner wall of the fixed plate 42. Multiple sets of guide rods 43 are inserted into the side end of the fixed plate 42, and the guide rods 43 are slidably connected to the fixed plate 42. The right end of the guide rod 43 is fixedly connected to the limiting plate 44. The guide rod 43 is a circular rod design, and the guide rod 43 is a circular rod design. 3. The left end is fixedly connected to the right end of the sealing head 45, and the left end of the sealing head 45 abuts against the right end of the inside of the sealing box 41; the guide rod 43 is sleeved with a second return spring 46, the right end of the second return spring 46 is fixedly connected to the fixed plate 42, and the left end of the second return spring 46 is fixedly connected to the right end of the sealing head 45; the inner wall of the sealing head 45 is fixedly connected to the outer side of the sealing ring 47; the inner wall of the sealing ring 47 is sleeved on the outer side of the second transmission rod 27, and the sealing ring 47 is slidably connected to the second transmission rod 27; the sealing ring 47 is made of rubber. During operation, the rotation of the second transmission rod 27 will simultaneously drive the fixed plate 42 to rotate. When the fixed plate 42 rotates, it will cause the left end of the sealing head 45 to rotate against the inner wall of the sealing box 41, thereby achieving a sealing effect and preventing the release agent from seeping out. At the same time, when the sealing head 45 becomes worn and thin, the second return spring 46 on the outside of the guide rod 43 will push the sealing head 45 to move to the left along the outside of the second transmission rod 27 through its own rebound force. At the same time, the sealing head 45 drives the sealing ring 47 to move along the outside of the second transmission rod 27, and the sealing ring 47 fits against the second transmission rod 27, thereby improving the sealing effect, until the sealing head 45 abuts against the inner wall of the sealing box 41, and the limiting plate 44 can play a limiting role.
