Abstract
Description
Technical Field
[0001] This utility model relates to the field of foamed seat cushion production technology, specifically to a mold opening mechanism for a foamed seat cushion molding die. Background Technology
[0002] In the production of foamed seat cushions, the mold opening and closing operations are crucial steps, directly affecting product quality and production efficiency. Traditional mold opening mechanisms mostly rely on a single drive method, such as hydraulic cylinders or mechanical transmission. While these methods can meet production needs to a certain extent, malfunctions often lead to the entire production line halting, severely impacting production progress and cost control. This is especially true in hydraulic cylinder-driven mold opening mechanisms, where the stability and reliability of the hydraulic cylinder directly affect whether the mold can open smoothly. However, in actual production, due to hydraulic oil leakage, hydraulic cylinder wear, or electrical control system malfunctions, the hydraulic cylinder sometimes fails to function properly, preventing the mold from opening smoothly and causing significant production disruptions. Therefore, we propose a mold opening mechanism for foamed seat cushion molding dies. Utility Model Content

[0021] like Figures 1-4As shown, this utility model provides a technical solution: a mold opening mechanism for a foamed seat cushion molding die, including a base 1, a support 2, a concave mold 3, and a convex mold 4. The support 2 is fixedly installed on the top of the base 1, and a moving groove 10 is opened on the top of the base 1. A support plate 5 is fixedly installed on the bottom of the concave mold 3, and a base plate 7 is provided below the support plate 5. An electric cylinder 6 is fixedly installed on the top of the base plate 7, and the support plate 5 is fixedly installed on the output end of the electric cylinder 6. An electric slide rail 9 is fixedly installed in a groove opened on the bottom of the inner wall of the moving groove 10. A connecting slide plate 8 is fixedly installed on the bottom of the base plate 7, and the connecting slide plate 8 is slidably connected to the electric slide rail 9. A hydraulic cylinder 11 is fixedly installed on the top of the support 2. The piston rod of the hydraulic cylinder 11 moves through the top of the bracket 2. The bottom of the piston rod of the hydraulic cylinder 11 is fixedly mounted with a mounting plate 14. A connecting component is provided between the mounting plate 14 and the punch 4. The top of the punch 4 is connected to the feed pipe 12 and the exhaust pipe 13. The top of the punch 4 is fixedly mounted with a hanging ring 28. The top of the bracket 2 is fixedly mounted with a double-head motor 29 near the rear side. The output end of the double-head motor 29 is fixedly mounted with a rotating shaft 30. The outer wall of the rotating shaft 30 is fixedly fitted with a take-up roller 31. A rope 33 is wound on the take-up roller 31. One end of the rope 33 is fixedly mounted on the outer wall of the take-up roller 31. The other end of the rope 33 moves through the top of the bracket 2, and the other end of the rope 33 is fixedly mounted with a hook 34.
[0022] The connecting assembly includes a frame 15 and a positioning post 19. The positioning post 19 is fixedly installed on the top of the punch 4. The positioning post 19 movably passes through the positioning hole opened on the mounting plate 14. The positioning post 19 movably passes through the positioning hole. The outer wall of the positioning post 19 has a slot 20. The frame 15 is engaged in the slot 20. A connecting rod 18 is fixedly installed on the inner side of the frame 15. A rod groove 16 is opened on one side of the mounting plate 14. The connecting rod 18 is inserted into the rod groove 16. A spring 17 is fixedly connected between one end of the connecting rod 18 and the inner wall of the rod groove 16.
[0023] A fixing plate 21 is fixedly installed on the top of the mounting plate 14. A shaft hole 27 is opened on the fixing plate 21. A connecting shaft 22 is movably inserted through the shaft hole 27. A torsion spring 26 is fixedly connected between the outer wall of the connecting shaft 22 and the inner wall of the shaft hole 27. A baffle 23 is fixedly installed on one end of the connecting shaft 22, and a clamping plate 24 is fixedly installed on the other end of the connecting shaft 22. A second clamping groove 25 is opened on the top of the clamping frame 15, and the clamping plate 24 is clamped in the second clamping groove 25.
[0024] Specifically, in the above technical solution, the mold opening mechanism of the foamed cushion molding die is controlled by hydraulic cylinder 11 to open and close the punch 4. When hydraulic cylinder 11 malfunctions and cannot perform the mold opening operation, the clamping plate 24 is rotated 90°, causing the clamping plate 24 to disengage from the clamping groove 25, so that the clamping plate 24 no longer limits the clamping frame 15. At this time, the clamping frame 15 can be pulled outward, causing the clamping frame 15 to disengage from the clamping groove 20, so that the clamping frame 15 no longer limits the positioning post 19. Then, the electric cylinder 6 is activated to retract, causing the electric cylinder 6 to drive the die 3 and punch 4 downward through the support plate 5, so that the punch 4 drives the positioning post 19 to disengage from the mounting plate 14. Then, the electric slide rail 9 is activated, causing the electric slide rail 9 to drive the connecting slide plate 8 to move backward, causing the connecting slide plate 8 to drive the base plate 7 to move backward, so that the base plate 7 is driven by the electric cylinder 6 and the support plate 5. The concave mold 3 and the convex mold 4 are moved to directly below the hook 34. The hook 34 can then be hooked onto the hanging ring 28. The dual-head motor 29 is then started, driving the rotating shaft 30 to rotate. The rotating shaft 30 drives the take-up roller 31 to rotate, causing the take-up roller 31 to retract the rope 33. The rope 33, through the hook 34 and hanging ring 28, moves the convex mold 4 upwards, disengaging it from the groove, thus completing the mold opening operation. This structure allows for two methods of mold opening, ensuring normal mold opening and the normal production of the foamed cushion, greatly improving production reliability and stability. The connecting components facilitate the disassembly and assembly of the convex mold 4 and the mounting plate 14, improving work efficiency and further ensuring mold opening efficiency in case of hydraulic cylinder 11 failure. The structure is simple and highly practical.
[0025] Furthermore, the card frame 15 is adapted to the card slot 20;
[0026] In this design, by setting a card frame 15, the card frame 15 can be inserted into the card slot 20, thereby limiting the positioning post 19.
[0027] Furthermore, the card plate 24 is compatible with the card slot 25;
[0028] The card plate 24 is designed to be inserted into the card slot 25, thereby limiting the position of the card frame 15 and ensuring the stability of the card frame 15 during use.
