[0002] Flatcar composite flooring refers to the flooring installed on railway flatcars. Since railway flatcars are freight cars without roofs or sideboards, flatcar composite flooring is typically installed to increase the friction between the cargo and the floor, thereby reducing the need for cargo securing devices and loading time. It also facilitates the connection of common flatcar securing equipment such as round nails and rivets. The production process of flatcar composite flooring generally includes: 1. Mixing wood particles with chemicals and other raw materials; 2. Compressing the mixture into molds; 3. Heat-treating the molded composite flooring; 4. Demolding; 5. Trimming rough edges and packaging for shipment.

[0030] 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.
[0031] Reference Figures 1 to 3 This utility model provides an embodiment of a flatbed composite flooring molding device, comprising a molding machine housing 1. A hydraulic cylinder 2 is fixedly connected to the top of the molding machine housing 1, and a top template 3 is fixedly connected to the driving end of the hydraulic cylinder 2. The hydraulic cylinder 2 is a device for controlling the movement of the top template 3, driving the top template 3 downward through a hydraulic system. A bottom mold 4 is fixedly connected to the bottom of the molding machine housing 1. The top template 3 moves downward through the drive of the hydraulic cylinder 2 to press the material against the bottom mold 4. The contact between the top template 3 and the bottom mold 4 generates pressure, thereby forming the material. Four dampers 5 are fixedly connected to the bottom of the molding machine housing 1. When the top template 3 is pressed down, it will partially contact the dampers 5 before contacting the bottom mold 4, thus buffering the impact force of the dampers 5 on the top template 3.
[0032] A support plate 6 is fixedly connected to the left side of the molding machine housing 1. A hydraulic cylinder 7 is fixedly connected to the top left side of the support plate 6. A telescopic rod 8 is fixedly connected to the drive end of the hydraulic cylinder 7. The hydraulic cylinder 7 is a hydraulically driven mechanical device used to control the movement of the telescopic rod 8. The liquid in the hydraulic cylinder applies pressure to push the piston, thereby driving the telescopic rod 8 to extend and retract along its axial direction.
[0033] The right end of the telescopic rod 8 is fixedly connected to a limiting sleeve 9. The bottom end of the limiting sleeve 9 is slidably connected to the top end of the support plate 6. The top end of the limiting sleeve 9 is fixedly connected to a support plate 10. The telescopic rod 8 is a mechanical component output by the hydraulic cylinder 7 and can move along its length. One end of it is connected to the hydraulic cylinder 7, and the other end is connected to the limiting sleeve 9. Its telescopic movement pushes the limiting sleeve 9 and the support plate 10 to move together.
[0034] refer to Figure 2 , Figure 3 A motor 11 is fixedly connected to the top right side of the support plate 10. The support plate 10 is a component fixedly connected to the limiting sleeve 9, mainly used to support and fix the motor 11 and other related components. Structurally, it fits tightly with the limiting sleeve 9 to ensure the stability of the entire system. The drive end of the motor 11 is fixedly connected to the limiting disk 12, and the top end of the limiting disk 12 is slidably connected to the bottom end of the support plate 10. The motor 11 is the power source for driving the limiting disk 12. It drives the limiting disk 12 to rotate by rotating, thereby causing the limiting post 13 to start rotating.
[0035] A limiting post 13 is fixedly connected to the bottom end of the limiting plate 12. The limiting plate 12 is a component driven by the motor 11, responsible for converting the rotational motion of the motor 11 into the rotation of the limiting post 13. The limiting plate 12, when rotating, also drives the limiting post 13 to rotate. An elliptical plate 14 is slidably connected to the bottom end of the limiting post 13. The limiting post 13 is fixed to the bottom end of the limiting plate 12 and rotates with the limiting plate 12. The elliptical plate 14 is mounted on the limiting post 13, and its rotation causes the elliptical plate 14 to slide left and right along the diameter of the limiting plate 12.
[0036] The limiting post 13 is externally slidably connected to the inner side of the elliptical plate 14. A guide plate 15 is fixedly connected to the left side of the elliptical plate 14. The elliptical plate 14 is connected to the limiting post 13, and the rotation of the limiting post 13 drives the elliptical plate 14 to slide. The guide plate 15 is fixed on the elliptical plate 14, which ensures that the sliding of the elliptical plate 14 within the limiting sleeve 9 is smooth. The guide plate 15 is externally slidably connected to the middle of the limiting sleeve 9, and its top end is slidably connected to the bottom end of the limiting plate 12. The guide plate 15 is fixed to the left side of the elliptical plate 14, and its function is to guide the elliptical plate 14 to slide in the middle of the limiting sleeve 9. The outer side of the guide plate 15 is slidably connected to the inner wall of the limiting sleeve 9 to ensure that the sliding trajectory of the elliptical plate 14 is accurate.
[0037] A cleaning assembly is fixedly connected to the bottom end of the guide plate 15. The cleaning assembly includes a sponge ring 16, the bottom end of which is slidably connected to the top end of the bottom mold 4. The top end of the sponge ring 16 is fixedly connected to the bottom end of the elliptical plate 14. A water inlet pipe 17 is fixedly connected to the left side of the sponge ring 16. The cleaning assembly, consisting of the sponge ring 16 and the water inlet pipe 17, is used to clean the inner wall of the bottom mold 4 after each operation. The sponge ring 16 is fixed to the top end of the elliptical plate 14, and its bottom end slides in contact with the top end of the bottom mold 4 to remove sawdust, dust, and other debris. The sponge ring 16, fixed to the bottom end of the elliptical plate 14, can clean the inner wall of the bottom mold 4 from the top. The surface of the sponge ring 16 has good adsorption properties to remove residue from the mold. The water inlet pipe 17, fixed to the left side of the sponge ring 16, supplies water to the sponge ring 16 to maintain its cleaning ability and moisture. The water inlet pipe 17 ensures that the sponge ring 16 maintains optimal cleaning performance during the cleaning process.
[0038] refer to Figure 4 A hydraulic cylinder 18 is fixedly connected to the bottom middle of the molding machine housing 1. A top column 19 is fixedly connected to the drive end of the hydraulic cylinder 18. The top column 19 is slidably connected to the inner wall of the middle part of the bottom mold 4. The hydraulic cylinder 18 is responsible for driving the movement of the top column 19. The top column 19 is moved upward by hydraulic action, thereby pushing the flatbed composite floor out of the bottom mold 4.
[0039] A groove 20 is formed at the bottom of the press mold housing 1. The outer side of the ejector pin 19 is slidably connected to the inner wall of the groove 20. The groove 20 is located in the middle of the bottom of the press mold housing 1 to accommodate the movement of the ejector pin 19. Its inner wall is slidably connected to the ejector pin 19 to ensure that the ejector pin 19 stably and accurately ejects the flatbed composite floor during movement. The ejector pin 19 extends and retracts upward under the drive of the hydraulic cylinder 3 18 to eject the flatbed composite floor from the bottom mold 4. The outer side of the ejector pin 19 is slidably connected to the inner wall of the groove 20 to ensure stable movement.
[0040] Connecting plates 21 are fixedly connected to the front and rear sides of the top post 19. Ejector pins 22 are fixedly connected to the middle of the connecting plates 21. The ejector pins 22 are slidably connected to the front and rear interior of the top end of the bottom mold 4. The connecting plates 21, fixed to the front and rear sides of the top post 19, provide support for the ejector pins 22. The connecting plates 21, through the ejector pins 22, further push the flatbed composite floor out of the bottom mold 4. The ejector pins 22, components on the connecting plates 21, press the flatbed composite floor upwards using the elastic force of the spring 23, ensuring the flatbed composite floor is completely removed from the bottom mold 4.
[0041] A spring 23 is fitted around the ejector pin 22. One end of the spring 23 is fixedly connected to the top of the inner wall of the groove 20, and the other end is fixedly connected to the top of the connecting plate 21. The spring 23, fitted around the ejector pin 22, provides elasticity to ensure that the ejector pin 22 can continue to push the flatbed composite floor upward during ejection. The two ends of the spring 23 are respectively fixed to the top of the inner wall of the groove 20 and the top of the connecting plate 21. The bottom of the molding machine housing 1 is fixedly connected to four corners with support legs 24. The support legs 24 are fixed to the four corners of the molding machine housing 1, providing stable support for the entire molding device. The structural design of the support legs 24 ensures that the equipment will not tip over due to imbalance during operation.
[0042] Working Principle: First, the hydraulic cylinder 7 drives the telescopic rod 8 to push the limiting sleeve 9 and the support plate 10 to the right, allowing the fixed motor 11 and the limiting plate 12 to move to the middle position of the molding machine housing 1. At this time, the motor 11 can be started, causing the limiting plate 12 and the limiting post 13 fixed at the bottom edge of the limiting plate 12 to start rotating. The rotating limiting post 13 will drive the elliptical plate 14 to slide, and with the guide plate 15 fixed to the elliptical plate 14 sliding in the middle of the limiting sleeve 9, the elliptical plate 14 will slide back and forth along the diameter of the limiting plate 12 when the limiting post 13 moves. At this time, the sponge ring 16 fixed at the top of the elliptical plate 14 will clean the inner wall of the bottom mold 4 at the top of the bottom mold 4, preventing sawdust, dust and other debris from remaining on the mold after each use.
[0043] After cleaning, start hydraulic cylinder 7 to drive telescopic rod 8 to move the fixed parts of limit sleeve 9 and support plate 10 to slide above limit sleeve 9, so that the molding device can perform molding operation.
[0044] Finally, place the material to be pressed on the top of the bottom mold 4. Then, activate hydraulic cylinder 2 to drive the top mold plate 3 downwards towards the bottom mold 4, so that the top mold plate 3 and the bottom mold 4 press the material together.
[0045] During the molding process, the cooling system is activated to cool the formed flatbed composite floor to an appropriate temperature. Then, hydraulic cylinder 2 is activated to drive the top platen 3 upward. At this time, hydraulic cylinder 3 18 is activated to drive the ejector pin 19 to eject the flatbed composite floor from the top of the bottom mold 4, achieving the first ejection of the flatbed composite floor. After the ejector pin 19 extends and retracts upward, the springs 23 on both sides of the ejector pin 19 are no longer stretched, so the ejector pin 22 fixed by the connecting plate 21 is pushed upward again by the elastic force of the spring 23 to push the flatbed composite floor from the top of the bottom mold 4, achieving the second ejection of the flatbed composite floor. This helps to quickly remove the flatbed floor from the mold, reduce waste in production, and improve production efficiency.
[0046] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
