Description

Technical Field

[0001] This utility model relates to the field of production mold technology, specifically to a production mold for polytetrafluoroethylene sheets. Background Technology

[0002] Polytetrafluoroethylene (PTFE) sheets refer to sheets made by molding PTFE dispersion resin with organic solvents as additives, or by machining or rolling blanks formed by molding or hydraulic methods. The molding process involves molding PTFE resin at room temperature, followed by sintering and cooling to produce molded sheets. Currently, molded sheets are prone to damage during demolding. To address the aforementioned issues, a utility model patent with publication number CN215550352U discloses a production mold for polytetrafluoroethylene (PTFE) sheets. This mold adjusts the depth of the groove by adjusting the position of the groove bottom, filling it with different weights of filler. Once the filler evenly fills the groove, it is fed into a molding machine. Molding parameters are set, and the bottom of the groove is raised to position b via a lifting device, allowing the sheet to be removed for the next process. However, the filler is at a high temperature when filling the groove and easily adheres to the inner wall of the mold before it has fully cooled. Directly lifting and removing the material can easily cause sticking, thus affecting the production quality of the PTFE sheets. Utility Model Content

[0013] 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.

[0014] Please see Figures 1 to 6 A production mold for polytetrafluoroethylene (PTFE) sheets includes an outer mold box 1, an inner mold box 2, cooling pipes 3, heat dissipation ring pipes 4, heat dissipation vents, a pusher plate 5, and impact hammer rods 6. The inner mold box 2 is installed inside the outer mold box 1, and a cooling space is formed between the outer mold box 1 and the inner mold box 2. Two cooling pipes 3 are provided, and the two cooling pipes 3 are symmetrically installed in the cooling space. Two heat dissipation ring pipes 4 are provided, and the two heat dissipation ring pipes 4 are respectively located on both sides of the two cooling pipes 3. Multiple heat dissipation vents are provided, and multiple heat dissipation vents are arrayed in each heat dissipation ring pipe 4. The pusher plate 5 is movably installed inside the inner mold box 2. Multiple impact hammer rods 6 are provided, and multiple impact hammer rods 6 are rotatably installed on both sides of the outer mold box 1. Each impact hammer rod is fixedly connected with a rubber pad 7, which reduces the contact wear between the impact hammer rod 6 and the outer wall of the outer mold box 1. At the same time, it can reduce the impact vibration on the impact hammer rod 6, the drive rod 11, the rotating rod 9, and the dual-head motor 8, and improve the service life of the above components.

[0015] refer to Figure 1 as well as Figure 3 A striking assembly is provided between multiple striking hammer rods 6. The striking assembly includes a dual-head motor 8, a rotating rod 9, a fixed cover 10, a driving rod 11, a main gear 12, and a driven wheel 13. The dual-head motor 8 is mounted on one side of the outer mold box 1 via a mounting bracket. There are two rotating rods 9, which are symmetrically connected to the dual-head motor 8. There are two fixed covers 10, which are symmetrically connected to both sides of the outer mold box 1. The rotating rods 9 and the fixed covers 10 are rotatably connected through each other. The driving rod 11 is rotatably mounted through each fixed cover 10. The main gear 12 is fixedly connected to each rotating rod 9. The driven wheel 13 is fixedly connected to each driving rod 11. The main gear 12 and the driven wheel 13 mesh with each other. The fixed cover 10 can protect the main gear 12 and the driven wheel 13. When the dual-head motor 8 is started, the two rotating rods 9 drive the two main gears 12 to rotate. The meshing of the two main gears 12 and the two driven wheels 13 drives the two driving rods 11 to rotate, so that the multiple hammer rods 6 drive the multiple rubber pads 7 to contact. When the multiple rubber pads 7 rotate, they will contact and deform with the outer wall of the outer mold box 1, thereby impacting and vibrating the outer wall of the outer mold box 1 to a certain extent. This can shake off the polytetrafluoroethylene sheet material that is stuck to the inner wall of the inner mold box 2, and then the molded polytetrafluoroethylene sheet can be quickly demolded and removed.

[0016] refer to Figure 1A sealing assembly is detachably installed between the outer mold box 1 and the inner mold box 2. The sealing assembly includes a sealing cover plate 14, a bracket 15, and a handle 16. The sealing cover plate 14 is detachably installed between the outer mold box 1 and the inner mold box 2. Multiple brackets 15 are provided, and multiple brackets 15 are fixedly connected to the top of the sealing cover plate 14. The brackets 15 are provided with a contact plane that matches the outer side wall of the outer mold box 1. Two handles 16 are provided, and two handles 16 are fixedly connected between multiple brackets 15 respectively, so as to facilitate the simultaneous movement of multiple brackets 15, so as to facilitate the movement, installation, and disassembly of the sealing cover plate 14. When the sealing cover 14 is installed between the outer mold box 1 and the inner mold box 2, multiple clips 15 will be placed on both sides of the outer mold box 1 to increase the stability of the sealing cover 14, thereby sealing the cooling space and improving the cooling effect on the polytetrafluoroethylene sheet.

[0017] refer to Figure 2 as well as Figure 4 The cooling pipe 3 is a continuous S-shape. There are two connecting pipes 17 between the two cooling pipes 3, and the two connecting pipes 17 are respectively connected to the water inlet pipe 18 and the water outlet pipe 19. The water inlet pipe 18 and the water outlet pipe 19 are respectively equipped with water inlet valve and water outlet valve. The water inlet pipe 18 and the air outlet pipe 22 are both connected to the cooling water circulation equipment. By opening the inlet and outlet valves, cooling water can circulate within the inlet pipe 18, outlet pipe 19, two connecting pipes 17, and two cooling pipe fittings 3. This allows for rapid cooling and molding of the PTFE sheet inside the inner mold box 2, and also reduces the adhesion of the PTFE sheet to the inner wall of the inner mold box 2, facilitating demolding.

[0018] refer to Figure 2 as well as Figure 5 Two support pipes 20 are connected between the two heat dissipation ring pipes 4. Both support pipes 20 are connected to the outer mold box 1 through the pipes. One side of each support pipe 20 is connected to an air inlet pipe 21 and an air outlet pipe 22. One side of the air inlet pipe 21 is connected to the air supply equipment. An air inlet valve and an air outlet valve are installed on the air inlet pipe 21 and the air outlet pipe 22, respectively. By opening the air inlet valve and the air outlet valve, the cooling air can circulate in the air inlet pipe 21, the air outlet pipe 22, the two support pipes 20 and the two cooling ring pipes 4, so that multiple heat dissipation ports can spray cooling evenly into the cooling space. While initially cooling the polytetrafluoroethylene sheet in the inner mold box 2, it can also quickly cool the circulating water in the two cooling pipes 3, further improving the cooling effect of the cooling pipes 3.

[0019] refer to Figure 2 as well as Figure 6The bottom of the outer mold box 1 is fixedly connected to the base frame 23, and an electric push rod 24 is installed on the base frame 23. The output end of the electric push rod 24 passes through the outer mold box 1 and the inner mold box 2 and is fixedly connected to the push plate 5. Activating the electric push rod 24 causes it to push the pusher plate 5, which in turn pushes the polytetrafluoroethylene sheet formed in the inner mold box 2 out of the mold box 2, thus improving the efficiency of the polytetrafluoroethylene sheet.

[0020] In summary, firstly, the PTFE sheet material is poured into the inner mold box 2, and then the PTFE sheet material is compacted and molded using a cover plate. Then, cooling water circulates through the inlet pipe 18 and outlet pipe 19 within the two connecting pipes 17 and two cooling pipe fittings 3, providing comprehensive and rapid cooling of the PTFE sheet material within the inner mold box 2. Simultaneously, heat dissipation air circulates through the air inlet pipe 21, air outlet pipe 22, and two support pipes 20 within the two heat dissipation ring pipes 4. While the cooling water in the cooling pipe fittings 3 is being cooled by blowing air, the PTFE sheet material within the inner mold box 2 can also be cooled again. The PTFE sheet material is cooled from all directions, and then the dual-head motor 8 is started, causing the two rotating rods 9 to drive the two driving rods 11 to rotate simultaneously through the meshing of the two main gears 12 and the two driven wheels 13. This allows multiple hammer rods 6 and multiple rubber pads 7 to vibrate and strike the outer wall of the outer mold box 1 from all directions, which speeds up the molding efficiency of the PTFE sheet and facilitates the demolding of the PTFE sheet. After the PTFE sheet is formed, the cover plate is removed, and the electric push rod 24 is started, causing the pusher plate 5 to push the PTFE sheet out.
