Sand-coated casting has become one of the important casting processes in modern industry with its high precision, excellent surface quality, and high production efficiency, providing a reliable solution for manufacturing complex parts. A core shooting machine is usually used to place a core box in the appropriate position, then inject or spray core material into the core box to form the required casting core.

[0003] In traditional core shooting machines, the frame serves as the support structure of the entire device, ensuring stability and structural strength of the machine. The system for moving the core box between different stations can be a conveyor belt or other types of automatic conveying devices. These systems ensure smooth movement of the core box during the work process, continuously completing each process. The injection system is a key component for injecting or spraying core material into the core box. This includes injectors, nozzles, or other types of precision control systems to ensure accurate distribution and filling of core material.

[0004] However, in traditional core shooting machines, the core box is often directly transported on the surface of the conveyor belt during the feeding process.

Specific implementation

[0022] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0023] Reference Figure 1 - Figure 2 An embodiment provided by the utility model: a special multi -station core -shooting machine of sand coating, including fixed platform 1, the fixed platform 1 side wall is fixedly connected with motor one 2, and the motor one 2 output end is fixedly connected with transmission shaft 3, and the transmission shaft 3 both ends are rotatably connected in the fixed platform 1, and the transmission shaft 3 outer wall is fixedly connected with rotary table 4, and the fixed platform 1 is internally provided with a plurality of fall plate grooves 5, and the fixed platform 1 is internally provided with a plurality of sliding tables 6, and the sliding table 6 is all slidingly connected in the fall plate groove 5, and the sliding table 6 top is fixedly connected with limit position platform 7, and the limit position platform 7 is rotatably connected with sliding shaft 8 in the inside, and the sliding shaft 8 is slidingly connected in the rotary table 4, and the sliding table 6 bottom is all fixedly connected with clamping plate 9, and the fixed platform 1 bottom is provided with transmission assembly, and the transmission assembly is used for transmitting material.

[0024] Specifically, the core box is moved by the transmission table 10. During the transmission process, the motor 2 drives the transmission shaft 3. The transmission shaft 3 rotates in the fixed table 1 and drives the rotary table 4 on the outer wall to rotate synchronously. The operation of the rotary table 4 not only drives the sliding shaft 8 in the inside, but also drives the limiting table 7 at both ends of the sliding shaft 8 to displace vertically after being stressed. The sliding table 6 at the bottom of the limiting table 7 slides in the drop plate groove 5, and the descending action of the limiting table 7 limits the movement range of the sliding table 6. The multiple sliding tables 6 slide alternately in the fixed table 1, ensuring that the bottom clamping plate 9 can accurately stop the core box on the surface of the transmission table 10. This design ensures that the core box can enter the rear of the transmission table 10 in an orderly manner and be ready to be processed by the injection table 11. Through such a structure, the process of sand-coated core injection can be kept orderly and uniform, thereby significantly improving the casting efficiency.

[0025] With reference to Figure 3 The transmission assembly comprises a transmission table 10 arranged at the bottom of the fixed table 1. The top of the transmission table 10 is provided with multiple injection tables 11. The side wall of the transmission table 10 is fixedly connected with a lower table 12. The inside of the lower table 12 is fixedly connected with multiple sliding columns 13. The outer wall of the sliding column 13 is slidingly connected with an upper table 14. The side wall of the sliding column 13 and the upper table 14 are both fixedly connected with multiple spray heads 22. The side wall of the lower table 12 is fixedly connected with a motor 15. The output end of the motor 15 is fixedly connected with a connecting rod 16. The side wall of the connecting rod 16 is rotatably connected in the inside of the lower table 12. The inside of the connecting rod 16 is rotatably connected with a connecting shaft 17. The outer wall of the connecting shaft 17 is rotatably connected with a connecting rod 18. The inside of the connecting rod 18 is rotatably connected with a connecting shaft 19. The outer wall of the connecting shaft 19 is rotatably connected with a connecting rod 20. One end of the connecting rod 20 is rotatably connected in the inside of the upper table 14. One end of the connecting shaft 19 and the connecting shaft 17 are both fixedly connected with a gear 21. The gears 21 are engaged with each other.

[0026] Specifically, during the sand-coated core process, the transmission table 10 may be left with residual core material after processing the material. In order to avoid cross-contamination of these residual core materials, the device is equipped with an additional cleaning mechanism. When the presence of core material on the surface of the transmission table 10 is detected, motor two 15 is started, motor two 15 outputs a rotating force to connecting rod one 16, causing connecting rod one 16 to rotate inside the lower table 12. One end of connecting rod one 16 is connected to connecting rod two 18, which is pulled to drive connecting rod three 20 to rotate on the side wall of the upper table 14 and change its inclination angle. This movement is achieved through the rotation of connecting shaft one 17 and connecting shaft two 19, which in turn drives gear 21 to rotate synchronously between the two tables, thereby driving the upper table 14 to repeatedly slide up and down on the outer wall of the slide column 13, thereby effectively cleaning the transmission table 10. The meshing relationship between the gears 21 ensures that the connecting rod two 18 always remains vertical. A plurality of spray heads 22 installed on the upper table 14 are activated during this process to spray cleaning agents or water. These spray heads 22 thoroughly clean the surface of the transmission table 10 through high-pressure spraying, ensuring that there is no residual core material. This automated cleaning mechanism not only improves the efficiency of the production process, but also effectively maintains the production capacity of the equipment and the quality standards of the core material.

[0027] Working principle: When the core box needs to be transported, first move it through the transmission table 10. At this time, start motor one 2, which outputs a rotating force to the transmission shaft 3. The transmission shaft 3 rotates inside the fixed table 1 while driving the turntable 4 on its outer wall to rotate synchronously. The rotation of the turntable 4 pulls the slide shaft 8 inside it. After being pulled, the slide shaft 8 drives the two limit tables 7 on its ends to vertically displace. At this time, the slide table 6 at the bottom of the limit table 7 can slide inside the drop plate groove 5, and the limit table 7 limits the descent distance of the slide table 6. The alternating sliding of multiple slide tables 6 inside the fixed table 1 allows the stop plate 9 at the bottom to stop the core box on the surface of the transmission table 10, allowing it to enter orderly behind the transmission table 10 and be injected through the injection table 11. This structure ensures the orderliness and uniformity of sand-coated core injection, improving casting efficiency. During the transmission of the material, the transmission table 10 may have core material on its surface due to injection. In order to avoid cross-contamination of the core material, start motor two 15, which outputs a rotating force to the connecting rod one 16 to drive it to rotate inside the lower table 12. At this time, the connecting rod two 18 at one end of the connecting rod one 16 is pulled to drive the connecting rod three 20 to rotate on the side wall of the upper table 14 and change its inclination angle. Through the rotation of the connecting shaft one 17 and the connecting shaft two 19, the gear 21 at one end is driven to rotate synchronously, and through the meshing relationship between the gears 21, the upper table 14 is repeatedly slid on the outer wall of the slide column 13 after being forced. In turn, multiple spray heads 22 efficiently clean the transmission table 10, avoiding cross-contamination of the core material and maintaining the production efficiency and core material quality of the equipment.

[0028] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
