A multi-point pouring device for producing large refractory parts

Abstract

This utility model belongs to the field of multi-point casting technology for refractory components, specifically relating to a multi-point casting device for the production of large refractory components. It includes a casting device, a track located on the bottom side of the casting device and adapted to it for movement, a side plate on the side surface of the casting device, a guide assembly on the surface of the side plate, and a clamping assembly connected to the bottom side of the guide assembly. In this utility model, when the drive motor is running, it drives the active bevel gear to rotate. When the active bevel gear rotates, it drives two bidirectional lead screws to rotate through the driven bevel gear and the connecting rod. When the bidirectional lead screws rotate, they drive two helical tubes on their surfaces to move closer to each other. When the two helical tubes move closer to each other, they drive the clamping blocks to move laterally closer to the surface of the track monorail through the clamping side plate. When the clamping blocks on both sides move to the side surface of the track monorail, the position of the side plate is fixed by friction, preventing inaccurate alignment with the preset casting port due to unstable positioning of the casting device during the casting process.

Description

Technical Field

[0001] This utility model belongs to the field of multi-point casting technology for refractory parts, specifically relating to a multi-point casting device for the production of large refractory parts. Background Technology

[0002] Large refractory components (such as ladle linings and rotary kiln bricks) are large in size and complex in structure. Traditional single-point casting easily leads to uneven material distribution and large density differences. Multi-point casting devices, by setting multiple pouring ports at different positions in the mold, in conjunction with guide pipes or nozzles, achieve synchronous material injection, ensuring uniform filling in each area. In the production of large refractory components, multi-point casting devices significantly improve production efficiency and product quality through structural optimization, automated control, and splash-proof and odor-proof design.

[0003] In the operation of existing multi-point casting devices for large refractory component production, the typical operating mode is as follows: the casting equipment moves along a pre-laid track surface, and when it reaches the preset casting position, the casting operation begins. However, due to the large overall mass of the casting equipment, the track will experience a certain degree of displacement due to the dynamic forces exerted by the equipment during movement and positioning; simultaneously, the vibration of the equipment itself will also be transmitted to the track structure. These factors collectively lead to instability in the casting position, specifically manifested as a shift in the relative position between the equipment and the mold. Consequently, it becomes impossible to accurately align the casting with the preset pouring gate, severely affecting the molding quality and production efficiency of the refractory components. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-point casting device for the production of large refractory parts, which aims to solve the problem of unstable casting position in existing casting devices. Specifically, the relative position between the equipment and the mold is offset, which makes it impossible to accurately align with the preset casting port during casting, seriously affecting the molding quality and production efficiency of refractory parts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-point casting device for the production of large refractory parts, including a casting device and a track provided on the bottom side of the casting device and adapted thereto for moving the casting device. A guide component is provided on the side plate surface of the side surface of the casting device. A clamping component is connected to the bottom side of the guide component. A driving component connected to the side plate is connected to the top of the clamping component. The driving component is used to drive the movement of the clamping component. A linkage component connected to the side plate is connected to the end of the driving component. The linkage component is used to drive the two sets of driving components to move simultaneously.

[0006] As a multi-point casting device for the production of large refractory parts according to this utility model, preferably, the guiding component includes two sets of guiding grooves and guiding blocks. The guiding grooves are provided at one end of the side plate. The top of the clamping component is connected to two guiding blocks that pass through the two guiding grooves respectively.

[0007] As a multi-point casting device for the production of large refractory parts according to this utility model, preferably, the longitudinal section of the guide block is T-shaped, and the width of the detailed part of the guide block is adapted to the width of the guide groove.

[0008] As a multi-point casting device for the production of large refractory parts according to this utility model, preferably, the clamping assembly includes two sets of clamping side plates and clamping blocks. The clamping side plates are connected to the bottom side of the guide block, and the inner wall of the guide block is connected to the clamping block. The clamping side plates and clamping blocks are arranged on both sides of the track monorail.

[0009] As a multi-point casting device for the production of large refractory parts according to this utility model, preferably, the driving assembly includes a driving block, a solenoid, a bidirectional lead screw and a bearing seat. The top of the two clamping side plates are respectively connected to the driving block that penetrates the side plate. The interior of the two driving blocks is respectively penetrated by a solenoid. The interior of the two solenoids is penetrated by a threaded bidirectional lead screw. The end of the bidirectional lead screw is sleeved with a bearing seat installed on the upper surface of the side plate.

[0010] As a multi-point casting device for the production of large refractory parts according to this utility model, preferably, the guiding component, clamping component and driving component are symmetrically arranged in two sets on both sides of the side plate.

[0011] As a multi-point casting device for the production of large refractory parts according to this utility model, preferably, the linkage component includes a connecting rod, a driven bevel gear, a drive motor and a driving bevel gear. The connecting rod is connected to the ends of two bidirectional lead screws. The driven bevel gear is connected to the surface of the connecting rod. The drive motor is installed on the upper surface of the side plate. The output end of the drive motor is connected to the driving bevel gear that meshes with the driven bevel gear.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In this invention, when the casting equipment moves to the casting position on the track, the drive motor can be activated. The drive motor drives the active bevel gear to rotate, which in turn drives the driven bevel gear. The driven bevel gear, in turn, drives the connecting rod to rotate, which in turn drives two bidirectional lead screws to rotate. The bidirectional lead screws, when rotating, cause two spiral tubes on their surfaces to move closer together. This movement of the spiral tubes, via the drive block, causes the clamping side plates connected to their bottoms to move closer together. The movement of the clamping side plates causes the clamping blocks to move laterally closer to the surface of the track monorail. When the clamping blocks on both sides reach the side surface of the track monorail, the friction between the clamping blocks and the monorail surface fixes the position of the side plates, thus fixing the position of the casting equipment. This prevents instability in the casting equipment's position during the casting process, which could lead to inaccurate alignment with the preset casting port, affecting the molding quality and production efficiency of the refractory parts.

Detailed Implementation

[0021] 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.

[0022] Please see Figures 1-7 The present invention provides the following technical solution: a multi-point casting device for the production of large refractory parts, including a casting device 1 and a track 2 provided on the bottom side of the casting device 1 and adapted thereto for moving the casting device 1. A guide component 4 is provided on the surface of the side plate 3 on the side surface of the casting device 1. A clamping component 5 is connected to the bottom side of the guide component 4. A drive component 6 connected to the side plate 3 is connected to the top of the clamping component 5. The drive component 6 is used to drive the movement of the clamping component 5. A linkage component 7 connected to the side plate 3 is connected to the end of the drive component 6. The linkage component 7 is used to drive the two sets of drive components 6 to move simultaneously.

[0023] When the casting equipment 1 moves to the casting position on the surface of the track 2, the casting equipment 1 is used to cast the casting port. Then, when the casting equipment 1 moves to another casting position on the surface of the track 2, the casting equipment 1 is used to cast the casting port again. The same method is used to cast other casting ports, thereby realizing multi-point casting for the production of large refractory parts.

[0024] Preferably, the guide assembly 4 includes two sets of guide grooves 401 and guide blocks 402. Two sets of guide grooves 401 are provided at one end of the side plate 3. The top of the clamping assembly 5 is connected to two guide blocks 402 that pass through the two guide grooves 401 respectively. Preferably, the guide assembly 4 includes two sets of guide grooves 401 and guide blocks 402. Two sets of guide grooves 401 are provided at one end of the side plate 3. The top of the clamping assembly 5 is connected to two guide blocks 402 that pass through the two guide grooves 401 respectively. In practical use, when the clamping component 5 is subjected to a force, it can drive the guide block 402 to slide inside the guide groove 401. This can limit the movement direction of the clamping component 5 and maintain stability during the movement of the clamping component 5.

[0025] Preferably, the clamping assembly 5 includes two sets of clamping side plates 501 and clamping blocks 502. The clamping side plates 501 are connected to the bottom side of the guide block 402, and the clamping blocks 502 are connected to the inner wall of the guide block 402. The clamping side plates 501 and clamping blocks 502 are located on both sides of the single rail of the track 2. In practical use, when the clamping side plate 501 drives the clamping block 502 to move laterally to the side surface of the monorail of the track 2, the friction between the clamping block 502 and the surface of the monorail can be increased, thus fixing the position of the side plate 3, thereby fixing the position of the casting equipment 1.

[0026] Preferably, the drive assembly 6 includes a drive block 601, a solenoid 602, a bidirectional lead screw 603, and a bearing seat 604. The tops of the two clamping side plates 501 are respectively connected to drive blocks 601 that penetrate the side plates 3. The interiors of the two drive blocks 601 are respectively connected to solenoids 602. The interiors of the two solenoids 602 are connected to threaded bidirectional lead screws 603. The ends of the bidirectional lead screws 603 are sleeved with bearing seats 604 installed on the upper surface of the side plates 3. In practical use, when the bidirectional lead screw 603 rotates, it can drive the two helical tubes 602 on its surface to move in opposite directions through the threaded connection. When the two helical tubes 602 move, they can drive the clamping components 5 connected at the bottom to move in the opposite direction, thereby adjusting the position of the two clamping components 5 and facilitating the clamping and release of the single rail of the track 2 by the clamping components 5.

[0027] Preferably, the guide assembly 4, the clamping assembly 5 and the drive assembly 6 are symmetrically arranged in two sets on both sides of the side plate 3.

[0028] Preferably, the linkage assembly 7 includes a docking rod 701, a driven bevel gear 702, a drive motor 703, and a driving bevel gear 704. The docking rod 701 is connected to the ends of two bidirectional lead screws 603. The driven bevel gear 702 is connected to the surface of the docking rod 701. The drive motor 703 is mounted on the upper surface of the side plate 3. The output end of the drive motor 703 is connected to the driving bevel gear 704, which meshes with the driven bevel gear 702. In practical use, when the drive motor 703 is running, it can drive the active bevel gear 704 to rotate. When the active bevel gear 704 rotates, it can drive the driven bevel gear 702 to rotate through the meshing structure. When the driven bevel gear 702 rotates, it can drive the docking rod 701 to rotate. When the docking rod 701 rotates, it can drive the two bidirectional lead screws 603 to rotate inside the bearing seat 604, thereby realizing the linkage of the bidirectional lead screws 603.

[0029] The working principle of this utility model in specific use is as follows: When the pouring equipment 1 moves to the pouring position on the track 2, the drive motor 703 can be run. When the drive motor 703 runs, it can drive the active bevel gear 704 to rotate. When the active bevel gear 704 rotates, it drives the driven bevel gear 702 to rotate. When the driven bevel gear 702 rotates, it can drive the connecting rod 701 to rotate, and through the connecting rod 701, it drives the two double-acting screws 603 to rotate. When the double-acting screws 603 rotate, they can drive the two helical tubes 602 on their surfaces to move closer to each other. When the two helical tubes 602 move closer to each other, the driving block 601 can drive the clamping side plates 501 connected to their bottoms to move closer to each other. The movement of the clamping side plates 501 can drive the clamping block 502 to move laterally towards the surface of the monorail of the track 2. When the clamping blocks 502 on both sides move to the side surface of the monorail of the track 2, the position of the side plate 3 can be fixed by the friction between the clamping block 502 and the surface of the monorail, thereby fixing the position of the pouring device 1, and then pouring the pouring hole through the pouring device 1.
