Description

Technical Field

[0001] This invention relates to the field of conductive slip ring technology, specifically a conductive slip ring demolding and casting device. Background Technology

[0002] Conductive slip rings are often produced using a mold casting process. Existing conventional casting and demolding devices mostly use an integral opening and closing mold with simple upper and lower positioning seats to complete the casting operation. The mold, positioning base and push rod are mostly linked and synchronized. The mold closing and demolding processes are all integrated synchronous movements. The structure is simple and mainly relies on the mold opening and closing to directly complete the workpiece removal. There is no independent workpiece temporary holding and limiting structure design.

[0003] In existing casting and demolding devices, the mold, upper base, and pusher components separate simultaneously during the demolding process. This can easily lead to misalignment of the conductive slip ring's axis after molding, uneven stress on the workpiece, and problems such as shell deformation and end face damage. At the same time, the lack of a step-by-step demolding limiting structure means that the workpiece is prone to shifting with the mold during demolding, resulting in poor positioning accuracy and making it easy to scrap products. The overall molding and demolding stability is insufficient, making it difficult to meet the requirements for high-precision and non-destructive production of conductive slip rings. Summary of the Invention

[0004] The purpose of this invention is to provide a conductive slip ring demolding and casting device to solve the problems mentioned in the background art.

A lower base is fixed between the mold bodies and on the top of the support base. An upper base is located directly above the lower base. The upper base is connected to a lifting mechanism, which drives the upper base to move up and down. Multiple abutments pass through the interior of each mold. One end of each abutment is connected to a driving mechanism, which drives the abutment to move relative to each other. The other end of each abutment is adapted to the inner wall of the mold body.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0021] In one embodiment, see Figure 1 and Figure 2 A conductive slip ring demolding and casting device includes a support base 1. Two symmetrically distributed vertical plates 2 are fixed on the top of the support base 1, and a top plate is fixed between the vertical plates 2. A mold body is symmetrically distributed below the top plate. Each mold body is connected to a translation mechanism 3, which is used to drive the mold body to move relative to each other. A lower base 7 is fixed between the mold bodies and on the top of the support base 1. An upper base 8 is located directly above the lower base 7. The upper base 8 is connected to a lifting mechanism 4, which is used to drive the upper base 8 to move up and down. Multiple abutment rods 9 pass through the inside of the mold. One end of each abutment rod 9 is connected to a driving mechanism 5, which is used to drive the abutment rod 9 to move relative to each other. The other end of the abutment rod 9 is adapted to the inner wall of the mold body.

[0022] In this embodiment, when casting the conductive slip ring, the lower end of the conductive slip ring's central shaft is inserted into the through hole at the top of the lower base 7. Then, the lifting mechanism 4 moves the upper base 8 downwards, allowing the upper end of the conductive slip ring's central shaft to be inserted into the through hole at the bottom of the upper base 8. After the upper end of the conductive slip ring's central shaft is inserted into the through hole at the bottom of the upper base 8, the translation mechanism 3 moves the two mold bodies closer together until they are tightly fitted together, and the mold bodies are tightly fitted with the side walls of the upper base 8 and the lower base 7. The outer diameters of the upper base 8 and the lower base 7 match the inner diameter of the mold bodies. Simultaneously, the abutment rod 9 penetrating the side wall of the mold body also moves closer, with its end fitting into the inner wall of the mold body. The conductive slip ring can then be cast. The casting hole can be located on the mold, or on the upper base 8 or the lower base 7; no specific limitation is made here. After the conductive slip ring is poured, the translation mechanism 3 drives the two mold bodies to separate from each other. At this time, the abutment rod 9 remains stationary, and the end of the abutment rod 9 always presses against the poured conductive slip ring. At the same time, the upper base 8 does not separate from the central axis of the conductive slip ring. When the two mold bodies separate to the set distance, the abutment rod 9 separates synchronously. At the same time, the upper base 8 moves upward and separates from the central axis of the conductive slip ring. Then, the workers can remove the poured conductive slip ring from the lower base 7. This device uses the upper base 8 and the lower base 7 to precisely position and limit the upper and lower ends of the conductive slip ring's central shaft. It works in conjunction with the translation mechanism 3 to drive the mold body to open and close, and the lifting mechanism 4 to control the raising and lowering of the upper base 8. It is also equipped with an independently operable abutment rod 9. During casting, the mold is closed and sealed to complete the molding. During demolding, the mold body is first separated, the abutment rod 9 is temporarily left to hold the workpiece in place, and the upper base 8 remains in contact without separation. After the mold is completely separated, the abutment rod 9 is simultaneously retracted and the upper base 8 is raised. This effectively avoids the problems of skewing, deformation, and shaft offset when the cast conductive slip ring is demolded, achieving smooth and damage-free demolding. The overall structure is simple, the positioning is accurate, and the demolding stability is good.

[0023] Please see Figure 1 The translation mechanism 3 includes a support rod 33 fixedly connected to the side wall of the mold body, and a movable plate 34 fixed to the other end of the support rod 33. The top plate is provided with a slide rail adapted to the movable plate 34. The movable plate 34 passes through the slide rail and is slidably connected to it. A motor 31 is fixed on the side wall of one of the vertical plates 2. A bidirectional threaded rod 32 is fixed to the output end of the motor 31. The bidirectional threaded rod 32 passes through the movable plate 34 and is threadedly connected to it.

[0024] When the translation mechanism 3 is working, the motor 31 drives the bidirectional threaded rod 32 to rotate. Utilizing the bidirectional thread rotation characteristic, the two moving plates 34 slide in opposite or opposite directions along the internal slide rails of the top plate. The moving plates 34 are fixed to the mold body via support rods 33, thus synchronously driving the mold bodies on both sides to achieve precise mold closing and opening actions. The entire system relies on the slide rails to guide and limit the moving plates 34, ensuring smooth mold translation and high alignment accuracy. The use of a screw thread drive ensures stable transmission, controllable start and stop, and smooth drive of the mold body to complete the opening and closing operations.

[0025] Please see Figure 1 and Figure 2 The lifting mechanism 4 includes a slide rod 43 fixedly connected to the upper base 8. The slide rod 43 passes through the top plate and is slidably connected to it. A pressure plate 42 is fixed to the top of the slide rod 43. The side of the pressure plate 42 is provided with symmetrically distributed trapezoidal blocks 41. A bidirectional threaded rod 32 passes through the trapezoidal blocks 41 and is threadedly connected to them. A guide rod 45 is fixed between the upright plates 2. The guide rod 45 passes through the trapezoidal blocks 41 and is slidably connected to them. A first spring 44 is sleeved on the outside of the slide rod 43. The two ends of the first spring 44 are fixedly connected to the bottom of the pressure plate 42 and the top of the top plate, respectively.

[0026] When the lifting mechanism 4 is working, the rotation of the bidirectional threaded rod 32 drives the two sets of trapezoidal blocks 41 to slide towards each other along the guide rod 45. During the sliding process, the trapezoidal blocks 41 press down on the pressure plate 42, overcoming the elastic force of the first spring 44 and pushing the slide rod 43 downward, thereby driving the upper base 8 downward to complete the mold closing and positioning. When the bidirectional threaded rod 32 rotates in the opposite direction, the trapezoidal blocks 41 move away from each other, releasing the downward pressure restriction on the pressure plate 42. The first spring 44 rebounds and lifts the pressure plate 42, driving the slide rod 43 and the upper base 8 to move upward synchronously to reset. The guide rod 45 plays a sliding limit and guiding role for the trapezoidal blocks 41, ensuring smooth lifting movement and accurate positioning.

[0027] Please see Figure 3 The driving mechanism 5 includes a baffle 51 fixedly connected to the end of the push rod 9. A first hydraulic rod 52 is fixed on the side of the baffle 51 away from the push rod 9. A hydraulic assembly is connected to the other end of the first hydraulic rod 52. The hydraulic assembly is used to push the first hydraulic rod 52. A limit plate 56 is fixed at the bottom of the top plate. The first hydraulic rod 52 passes through the limit plate 56 and is slidably connected to it. A fixing assembly is provided inside the limit plate 56. The fixing assembly is used to fix the position of the first hydraulic rod 52.

[0028] When the trapezoidal block 41 presses down on the pressure plate 42, the hydraulic assembly provides power to the first hydraulic rod 52. The first hydraulic rod 52 drives the abutment rod 9 to perform horizontal telescopic movement via the baffle 51. At this time, the abutment rod 9 moves closer to the mold body synchronously. When the mold body is tightly fitted, the fixing component inside the limiting plate 56 just completes the locking and fixing of the first hydraulic rod 52. After the conductive slip ring is poured, the mold bodies separate. At this time, the abutment rod 9 remains stationary under the locking action of the fixing component, so that the abutment rod 9 can press against the workpiece for a long time, satisfying the step-by-step demolding condition of the mold separating first and the abutment rod 9 retracting later. The action is stable and the positioning is reliable.

[0029] Please see Figure 2 and Figure 3 The hydraulic assembly includes a second hydraulic cylinder 59 fixed to the top of the top plate, a piston 58 slidably connected inside the second hydraulic cylinder 59, a second hydraulic rod 57 fixed to the top of the piston 58, and the top of the second hydraulic rod 57 fixedly connected to the bottom of the pressure plate 42; a support plate 55 is fixed to the bottom of the top plate, a first hydraulic cylinder 53 is fixed to the side wall of the support plate 55, a first hydraulic rod 52 passes through the support plate 55 and extends into the interior of the first hydraulic cylinder 53, and the first hydraulic cylinder 53 is connected to the second hydraulic cylinder 59 through a guide pipe 54.

[0030] The hydraulic assembly connects the first hydraulic cylinder 53 and the second hydraulic cylinder 59 via the guide pipe 54, forming a linked hydraulic circuit. When the pressure plate 42 moves up and down, it drives the second hydraulic rod 57 and piston 58 to slide inside the second hydraulic cylinder 59, changing the hydraulic pressure inside the cylinder. Hydraulic oil is then supplied to the first hydraulic cylinder 53 through the guide pipe 54, thereby driving the first hydraulic rod 52 to extend and retract. The support plate 55 provides fixed support for the first hydraulic cylinder 53. The entire assembly utilizes the mechanical action of the upper base 8 to raise and lower, converting it into hydraulic power. This synchronously controls the advance and retreat of the push rod 9, eliminating the need for an additional power source. The structure exhibits strong linkage and precise action coordination.

[0031] Please see Figure 4 The fixing component includes a groove disposed inside the limiting plate 56, and a locking block 511 is slidably connected inside the groove. The locking block 511 is connected to the inner wall of the groove by a second spring 512. The first hydraulic rod 52 has a locking groove 510 on its side wall that is adapted to the locking block 511. The locking block 511 is connected to a traction component, which is used to pull the locking block 511 out of the locking groove 510.

[0032] The fixing component pushes the locking block 511 with the second spring 512. When the mold body is tightly fitted, the locking block 511 is just aligned with the slot 510. Under the elastic force of the second spring 512, the locking block 511 automatically locks into the slot 510, thereby locking the position of the first hydraulic rod 52 and maintaining the pressing state of the push rod 9. When the mold body is separated to the set position, the traction component automatically pulls the locking block 511 away from the slot 510, releasing the limiting constraint on the first hydraulic rod 52, and thus releasing the pressing limit of the push rod 9 on the conductive slip ring after casting.

[0033] Please see Figure 4 The traction component includes a push rod 516 that passes through the limiting plate 56. The push rod 516 is slidably connected to the limiting plate 56. A push block 513 is fixed to the end of the push rod 516. The push block 513 is connected to the side wall of the limiting plate 56 through a third spring 514. A traction rope 515 is fixed to the side wall of the push block 513. The other end of the traction rope 515 extends into the groove and is fixedly connected to the end of the locking block 511.

[0034] When the mold body separates to the set distance, the moving plate 34 presses against the push rod 516, and the push rod 516 drives the push block 513 to move. The push block 513 pulls the locking block 511 back into the groove through the traction rope 515, releasing the locking block 511 from the first hydraulic rod 52, so that the abutment rod 9 can retract and reset. The third spring 514 can provide the reset elastic force for the push block 513, which makes it easy for the locking block 511 to be locked again in the slot 510.

[0035] Working principle: When this device is working, the lower end of the conductive slip ring central shaft is first placed in the through hole of the lower base 7. The lifting mechanism 4 drives the trapezoidal block 41 to slide and press down the pressure plate 42 through the bidirectional threaded rod 32, which drives the slide rod 43 and the upper base 8 to move down, positioning and clamping the upper end of the conductive slip ring central shaft. At the same time, the motor 31 drives the bidirectional threaded rod 32 to rotate, which drives the two moving plates 34 to slide towards each other along the slide rail. Through the support rod 33, the mold body is driven to complete the mold closing and fitting. The downward movement of the pressure plate 42 synchronously drives the second hydraulic rod 57 and the piston 58 to move. The hydraulic power is transmitted through the guide pipe 54 to drive the first hydraulic rod 52 to extend and retract, which drives the abutment rod 9 to move closer to and fit against the inner wall of the mold synchronously with the mold. After the mold is closed, the locking block 511 of the fixing component is locked into the slot 510 under the action of the second spring 512, locking the position of the first hydraulic rod 52 and the abutment rod 9. After the casting is completed, the bidirectional threaded rod 32 reverses and drives the mold body to separate to both sides. At this time, the abutment rod 9 is locked by the locking block 511 and still presses against the workpiece, while the upper base 8 remains in position. When the mold is separated to the set position, the moving plate 34 squeezes the push rod 516, which drives the push block 513 to overcome the tension of the third spring 514 and pulls back the locking block 511 through the traction rope 515 to release the lock. The first hydraulic rod 52 drives the abutment rod 9 to retract, and at the same time the first spring 44 rebounds to make the upper base 8 move upward to reset. Finally, the molded workpiece is removed, and the whole process of step-by-step non-destructive demolding is realized.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
