Description
Technical Field
[0001] This utility model relates to the field of elevator counterweight processing technology, and in particular to a pressing mold for producing elevator counterweights. Background Technology
[0002] In modern buildings, elevators are crucial vertical transportation equipment, and their safe and efficient operation is of paramount importance. Elevator counterweights, as core components balancing the weight of the elevator car and ensuring stable elevator operation, have extremely high requirements for quality and production efficiency. Traditional pressing molds for elevator counterweight production have revealed numerous problems in long-term practice, such as complex mold structures leading to cumbersome and costly production operations; uneven pressure distribution during pressing, resulting in inconsistent counterweight density and affecting product quality stability; and poor mold versatility, making it difficult to adapt to the production needs of counterweights of different specifications. These issues severely restrict the development of the elevator counterweight manufacturing industry, necessitating the development of a new type of pressing mold for elevator counterweight production to solve these problems.
[0003] A search revealed Chinese patent publication number CN211708054U, which discloses a pressing mold for elevator counterweights, relating to the field of elevator counterweight processing. The mold includes a support frame, a mounting plate fixedly connected to the middle of the support frame, a motor fixedly mounted on the upper surface of the mounting plate, a first flywheel fixedly connected to the middle of one side of the motor via a rotating shaft, a belt movably connected to the middle of the first flywheel, a second flywheel movably connected inside the belt, a rotating rod fixedly connected to the middle of the second flywheel, and cams fixedly connected to both ends of the rotating rod.
[0004] The aforementioned patent states in its specification that "through the coordinated arrangement of motor 3, first flywheel 4, belt 5, and second flywheel 6, the rotating rod 7 can be driven to rotate, thereby driving the cam 8 to rotate, and the bearing box 9 can be shaken, preventing air from entering the counterweight, thus reducing the error between the counterweights." However, the cam shaking mainly causes the bearing box to shake irregularly through the rotation of the eccentric wheel. The movement trajectory of the concrete in the bearing box is relatively complex, which can lead to a certain degree of separation of aggregates of different particle sizes during the shaking process, resulting in stratification. The cam shaking relies on the mechanical contact between the cam and the bearing box to transmit motion. During long-term operation, the cam and the parts in contact with it are prone to wear due to friction, requiring regular replacement of parts, resulting in high maintenance costs. Therefore, a pressing mold for elevator counterweight production is proposed to solve the above problems. Utility Model Content

[0015] As a further description of the above technical solution:
[0016] The vibration mechanism includes a second rotating column, which is rotatably connected to the outside of the support plate. An eccentric wheel is fixedly connected to the outside of the second rotating column. A fixed box is fixedly connected to the top of the support plate. A driven block is slidably connected inside the fixed box. A telescopic column is fixedly connected to the end of the driven block away from the eccentric wheel. A telescopic spring is sleeved on the outside of the telescopic column. An impact block is fixedly connected to the outside of the bearing box. A transmission assembly is provided on the outside of the second rotating column.
[0017] The above technical solution involves installing the collecting block and the driven block to cause the entire load-bearing box to vibrate, effectively reducing air bubbles in the concrete inside the mold, improving the quality of the elevator counterweight, and enhancing product performance.
[0018] As a further description of the above technical solution:
[0019] The transmission assembly includes a second pulley, the inside of which is fixedly connected to the outside of the second rotating column, and the outside of which is coupled with a second transmission belt;

[0030] This utility model has the following beneficial effects:
[0031] 1. In this utility model, when producing elevator counterweight blocks, firstly, the top mold and bottom mold are placed in the bearing box. After injecting molten slurry, the motor is started. The motor drives the rotating column to rotate, which drives the pulley through the transmission wheel and transmission belt, causing the rotating shaft to rotate. This, in turn, causes the rotating rod to drive the connecting block, enabling the bearing box to slide back and forth within the fixed column. The reciprocating motion allows the concrete to move regularly in the vertical direction, resulting in more uniform force on each part of the concrete. This effectively reduces aggregate segregation and improves the uniformity of the concrete. Relatively speaking, the friction between the reciprocating moving parts is smaller, resulting in lower wear on the equipment, extending the service life of the equipment, and reducing maintenance frequency and costs.
[0032] 2. In this utility model, during the process of the drive mechanism driving the load box to reciprocate up and down, the second transmission wheel drives the second transmission belt, which in turn drives the second rotating column. The eccentric wheel rotates accordingly, and the eccentric wheel alternately squeezes and releases the driven block. Under the action of the telescopic spring, the driven block hits the impact block, giving the load box vibration. This vibration effectively reduces the air bubbles in the molten slurry between the molds, further improving the quality of the elevator counterweight and optimizing the counterweight production process in many ways.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0041] Reference Figures 1 to 3 This utility model provides an embodiment of a pressing mold for producing elevator counterweight blocks, including a support plate 1. A reciprocating mechanism 3 is provided inside the support plate 1. A base plate 2 is fixedly connected to the bottom end of the support plate 1. A driving mechanism 4 is provided at the top end of the base plate 2. A vibration mechanism 6 is provided at the top end of the support plate 1. The support plate 1 serves as the main supporting component of the entire mold, providing a foundation for the installation and fixation of subsequent structures, ensuring the overall stability and structural strength of the mold. The reciprocating mechanism 3 includes a rotating shaft 301. The external part of the rotating shaft 301 is rotatably connected to the inside of the support plate 1. The rotating shaft 301 is the key rotating component of the reciprocating mechanism 3. The rotation of the rotating shaft 301 drives the movement of subsequent structures. A rotating rod 302 is fixedly connected to the external part of the rotating shaft 301. A transmission rod 303 is rotatably connected to the end of the rotating rod 302 away from the rotating shaft 301. The rotating rod 302 plays the role of transmitting the power of the rotating shaft 301, so that the rotation can be further transmitted to the transmission rod 303.
[0042] A connecting block 304 is rotatably connected to the top of the transmission rod 303. Bearing boxes 5 are fixedly connected to both ends of the connecting block 304. The connecting block 304 connects the movement of the transmission rod 303 with the bearing boxes 5, allowing the bearing boxes 5 to move in tandem with the transmission rod 303. Sliding blocks 306 are fixedly connected to the far sides of both bearing boxes 5. Fixed posts 305 are slidably connected to the outside of the sliding blocks 306. The cooperation between the sliding blocks 306 and the fixed posts 305 restricts the movement trajectory of the bearing boxes 5, limiting their movement to the area around the fixed posts. The reciprocating sliding in the direction of 305 ensures the stability and accuracy of the movement. A drive assembly 307 is provided on the outside of the rotating shaft 301. The drive assembly 307 includes a pulley 3072, which is internally connected to the outside of the rotating shaft 301. A transmission belt 3071 is coupled to the outside of the pulley 3072. The drive assembly 307 transmits power to the rotating shaft 301 through the cooperation of the pulley 3072 and the transmission belt 3071, thereby realizing the rotation of the rotating shaft 301.
[0043] The drive mechanism 4 includes a motor 401, the bottom end of which is fixedly connected to the top of the base plate 2. The motor 401 serves as the power source for the entire mold, providing the necessary power for the mold's operation. Its stable power output is crucial for ensuring the normal operation of the mold. A rotating column 402 is fixedly connected to the drive end of the motor 401. A transmission wheel 403 and a transmission wheel 404 are fixedly connected to the outside of the rotating column 402. The rotating column 402 transmits the power of the motor 401 to the transmission wheel 403 and the transmission wheel 404, thereby realizing the distribution and transmission of power.
[0044] Specifically, the support plate 1 provides support and installation foundation for the mold, ensuring overall stability. The motor 401 in the drive mechanism 4 serves as a power source, outputting power through the rotating column 402 and the transmission wheel. The reciprocating mechanism 3, with the help of components such as the rotating shaft 301, rotating rod 302, transmission rod 303, and connecting block 304, drives the bearing box 5 to reciprocate stably and accurately along the fixed column 305 via the sliding block 306, providing motion conditions for concrete-related operations.
[0045] Reference Figures 3 to 5The vibration mechanism 6 includes a rotating column 601, which is externally rotatably connected to the inside of the support plate 1. An eccentric wheel 602 is fixedly connected to the outside of the rotating column 601. The rotating column 601 is the core rotating component of the vibration mechanism 6. The rotation of the rotating column 601 drives the rotation of the eccentric wheel 602, thereby generating a vibration effect. A fixed box 603 is fixedly connected to the top of the support plate 1. A driven block 604 is slidably connected inside the fixed box 603. The fixed box 603 provides sliding space for the driven block 604 and plays a certain role in restricting and protecting the movement of the driven block 604. A telescopic column 605 is fixedly connected to the end of the driven block 604 away from the eccentric wheel 602. A telescopic spring 606 is sleeved on the outside of the telescopic column 605. The combination of the telescopic column 605 and the telescopic spring 606 enables the driven block 604 to generate elastic telescopic movement when squeezed and released by the eccentric wheel 602, thereby realizing the vibration of the bearing box 5.
[0046] An impact-receiving block 607 is fixedly connected to the outside of the bearing box 5. The impact-receiving block 607 can effectively receive the impact force of the driven block 604 and transmit it to the bearing box 5, causing the bearing box 5 to vibrate. A transmission assembly 608 is provided on the outside of the rotating column 601. The transmission assembly 608 includes a pulley 6081, which is fixedly connected to the outside of the rotating column 601. A transmission belt 6082 is coupled to the outside of the pulley 6081, and the transmission belt 6082 is coupled to the inside of the transmission belt. The drive wheel 404 is externally coupled to the transmission belt 3071, which is internally coupled to the drive wheel 403. The transmission assembly 608 transmits the power of the drive mechanism 4 to the rotating column 601 through the cooperation of the pulley 6081 and the transmission belt 6082, thereby realizing the operation of the vibration mechanism 6. The front end of the telescopic column 605 is fixedly connected to the inside of the fixed box 603, the front end of the telescopic spring 606 is fixedly connected to the inside of the fixed box 603, and the other end of the telescopic spring 606 is fixedly connected to the front end of the driven block 604.
[0047] Specifically, regarding the vibration mechanism 6, the rotating column 601 drives the eccentric wheel 602 to rotate. The eccentric wheel 602 presses against the driven block 604 inside the fixed box 603. The driven block 604 relies on the telescopic column 605 and the telescopic spring 606 to generate elastic telescopic movement, impacting the impact block 607 outside the bearing box 5, thereby vibrating the bearing box 5. The transmission component 608 transmits the power of the drive mechanism 4 to the rotating column 601 through the pulley 6081 and the transmission belt 6082, ensuring the normal operation of the vibration mechanism 6, thereby reducing concrete air bubbles in the mold and improving the quality of the elevator counterweight.
[0048] Working principle: When the processing personnel need to produce elevator counterweights, they place the top mold 8 and bottom mold 7 into the bearing box 5. Molten slurry is added between the top mold 8 and bottom mold 7 through the injection port at the top of the top mold 8. After injection, the motor 401 is started. The motor 401 drives the rotating column 402 to rotate, which in turn causes the transmission wheel 403 to drive the transmission belt 3071 to move. This causes the belt pulley 3072 to drive the rotating shaft 301 to rotate inside the support plate 1. The rotating rod 302 then drives the connecting block 304 to rotate, and so on, through the connecting block 304... The connection between 04 and the two bearing boxes 5 allows the two bearing boxes 5 to slide back and forth inside the fixed column 305 via the sliding block 306. The reciprocating lifting and lowering can be controlled by adjusting the height or frequency of the lifting and lowering to generate a stronger up-and-down impact on the concrete inside the mold. This impact makes it easier for the air inside the concrete to be expelled. For some molds with complex shapes and dense reinforcement, the reciprocating lifting and lowering can more effectively fill the concrete into all corners and improve the density of the concrete. When the detection block 9 detects that the outside of the top mold 8 has slid into the inside of the bearing box 5, the lifting and lowering and the injection of molten grout are canceled.
[0049] When the drive mechanism 4 drives the reciprocating mechanism 3 to reciprocate the lifting and lowering of the carrier box 5, the transmission wheel 404 drives the transmission belt 6082 to move, causing the belt pulley 6081 to drive the rotating column 601 to rotate inside the support plate 1. This causes the eccentric wheel 602 to reciprocate and compress the driven block 604, thereby causing the driven block 604 to slide inside the fixed box 603. When the eccentric wheel 602 releases its pressure on the driven block 604, the telescopic spring 606 will quickly push the driven block 604 to slide outside the fixed box 603 until the driven block 604 collides with the impact block 607, thereby generating vibration in the carrier box 5 to reduce air bubbles in the molten slurry between the molds, thus improving the quality of the elevator counterweight.
[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
