Description

Technical Field

[0001] This application relates to the field of molding apparatus technology, and in particular to a PTFE plate molding apparatus with a cooling structure. Background Technology

[0002] Polytetrafluoroethylene (PTFE) sheets (also called PTFE sheets, Teflon sheets, or PTFE plates) are made by molding PTFE resin at room temperature, followed by sintering and cooling. Various PTFE products have played a crucial role in the national economy, including chemical, machinery, electronics, electrical appliances, military, aerospace, environmental protection, and bridge construction.

[0003] The existing Chinese patent (authorization announcement number: CN219311826U) mentions a mold cooling device for PET sheet compression molding process. It can heat the molding groove through the heating pipe and press the molding die together. The cooling liquid in the cooling pipe circulates and cools the molding die, thereby accelerating the cooling and molding speed of PET sheet. Since the molding die does not directly contact the molding mold and molding groove during the cooling process, the impact on the temperature of the molding mold and molding groove during the cooling process can be reduced. This avoids the need to consume more energy to heat the molding die to the appropriate temperature during continuous processing, thus reducing energy consumption and making it highly practical.

[0004] In existing PTFE plate cooling systems, most systems use coolant to lower the temperature of the PTFE plate. However, over time and with increased usage frequency, the coolant gradually absorbs heat, causing its temperature to rise. As the temperature rises, the coolant becomes less effective at cooling the PTFE plate, potentially resulting in poor cooling performance. Utility Model Content

[0005] The purpose of this application is to provide a PTFE sheet molding device with a cooling structure to address the problem that the cooling effect of the coolant on the PTFE sheet is low after the temperature rises, which may lead to poor cooling effect of the PTFE sheet.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A PTFE sheet molding device with a cooling structure includes a base plate, two sets of support legs symmetrically installed on the bottom of the base plate, a working frame fixedly connected to the top of the base plate, a hydraulic telescopic rod fixedly connected to the top of the working frame, the output end of the hydraulic telescopic rod passing through the working frame and fixedly connected to an upper mold, a lower mold installed on the top of the base plate, a water tank fixedly connected between several of the support legs, a water pump fixedly connected to the outside of the water tank, the inlet end of the water pump communicating with the water tank, a water pipe one installed at the outlet end of the water pump, a water pipe two installed inside the upper mold, the end of the water pipe one away from the water pump passing through the upper mold and communicating with the water pipe two, a water pipe three installed at the end of the water pipe two away from the water pipe one, the end of the water pipe three away from the water pipe two communicating with the water tank, and a cooling mechanism provided inside the water tank.

[0008] By adopting the above technical solution, the raw material is placed in the lower mold, the hydraulic telescopic rod is activated, and the hydraulic telescopic rod drives the upper mold to move downward and close with the lower mold, applying pressure to the raw material in the mold and pressing it into a blank of the required shape at room temperature. After the molding is completed, the water pump is activated, and the coolant flows in the water pipe 2, absorbing the heat of the upper mold and the blank, and cooling the blank. After the blank is cooled to a certain temperature, the hydraulic telescopic rod drives the upper mold to move upward, opening the mold and removing the formed PTFE sheet from the mold, completing one molding process. The cooling mechanism can be used to measure the cooling effect of the coolant.

[0009] Furthermore, the refrigeration mechanism includes a heat dissipation cylinder installed inside the water tank. The top of the heat dissipation cylinder penetrates the water tank and is set as an opening. A heat dissipation frame is fixedly connected to the top of the water tank. Ventilation holes are symmetrically opened on the outer side of the top of the heat dissipation frame. A fan is installed inside the heat dissipation frame at the top of the water tank. The blowing end of the fan is adapted to the ventilation hole.

[0010] By adopting the above technical solution, by starting the first fan, the blowing end of the first fan is matched with the ventilation hole, so that the hot air inside the heat sink frame is discharged through the ventilation hole, thereby forming a heat exchange with the outside air.

[0011] Furthermore, a second fan is installed inside the heat dissipation frame at the top of the water tank, and the blowing end of the second fan is adapted to the ventilation hole.

[0012] By adopting the above technical solution, the heat exchange rate between the coolant and the outside air is increased, thereby further improving the heat exchange efficiency.

[0013] Furthermore, a mounting frame is symmetrically fixedly connected to the outer side of the heat dissipation frame, a filter plate is slidably arranged on the inner side of the mounting frame, a handle is fixedly connected to the top of the filter plate, and the filter plate is adapted to the ventilation hole.

[0014] By adopting the above technical solution, the filter plate can filter the air entering the heat sink frame, thereby reducing dust entering the heat sink cylinder.

[0015] Furthermore, two sets of positioning frames are symmetrically fixedly connected to the top of the heat dissipation frame. A spring is fixedly connected to the inner side of the positioning frame. A movable plate is fixedly connected to the top of the spring. A rotating rod is fixedly connected to the top of the movable plate. A rotating plate is rotatably connected to the top of the rotating rod. The bottom of the rotating plate overlaps with the filter plate.

[0016] By adopting the above technical solution, the rotating plate is rotated to the top of the filter plate, and then the rotating plate is released. At this time, the elastic potential energy of the spring is released, causing the rotating plate to move downward and abut against the top of the filter plate to fix it.

[0017] Furthermore, the inner side of the positioning frame is symmetrically provided with sliding grooves, and the outer side of the moving plate is symmetrically fixedly connected with sliders. The sliders are adapted to the sliding grooves and are slidably connected to the sliding grooves.

[0018] By adopting the above technical solution, the slider and the groove provide guidance for the moving plate, so that the moving plate can maintain the correct motion trajectory when moving.

[0019] In summary, this application includes at least one of the following beneficial effects;

[0020] 1. In this application, by starting the fan, the hot air inside the heat sink is discharged through the ventilation holes, thereby exchanging heat with the outside air, which increases the heat exchange rate between the coolant and the outside air. The flowing air carries away the temperature of the coolant, allowing the coolant in the water tank to dissipate heat quickly, thus maintaining the cooling effect of the coolant.

[0021] 2. In this application, when fixing the filter plate, the rotating plate is rotated to the top of the filter plate, and then the rotating plate is released. At this time, the elastic potential energy of the spring is released, causing the rotating plate to move downward and abut against the top of the filter plate to fix it, thereby limiting and fixing the filter plate and improving the stability of the filter plate.

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a PTFE plate molding device with a cooling structure.

[0030] Reference Figure 1 and Figure 2 A PTFE sheet molding device with a cooling structure includes a base plate 1. Two sets of support legs 2 are symmetrically installed on the bottom of the base plate 1. A working frame 3 is fixedly connected to the top of the base plate 1. A hydraulic telescopic rod 4 is fixedly connected to the top of the working frame 3. The output end of the hydraulic telescopic rod 4 passes through the working frame 3 and is fixedly connected to an upper mold 5. A lower mold 6 is installed on the top of the base plate 1. A water tank 8 is fixedly connected between several support legs 2. A water pump 9 is fixedly connected to the outside of the water tank 8. The inlet end of the water pump 9 is connected to the water tank 8. A water pipe 10 is installed at the outlet end of the water pump 9. A water pipe 21 is installed inside the upper mold 5. The end of the water pipe 10 away from the water pump 9 passes through the upper mold 5 and is connected to the water pipe 21. A water pipe 32 is installed at the end of the water pipe 21 away from the water pipe 10. The end of the water pipe 32 away from the water pipe 21 is connected to the water tank 8. A cooling mechanism is provided inside the water tank 8.

[0031] First, the raw material is placed into the lower mold 6. The hydraulic telescopic rod 4 is activated, which moves the upper mold 5 downward and closes with the lower mold 6, applying pressure to the raw material inside the mold. The material is then pressed into the required shape at room temperature. After molding, the water pump 9 is activated, which draws the coolant from the water tank 8 through the water pipe 10 and sends it into the water pipe 11 inside the upper mold 5. The coolant flows in the water pipe 11, absorbing the heat from the upper mold 5 and the raw material, thus cooling the raw material. Once the raw material has cooled to a certain temperature, the hydraulic telescopic rod 4 moves the upper mold 5 upward, opening the mold and removing the molded PTFE sheet from the mold, completing one molding process. The cooling mechanism can be used to measure the cooling effect of the coolant.

[0032] Reference Figures 1 to 4The refrigeration mechanism includes a heat dissipation cylinder 13 installed inside the water tank 8. The top of the heat dissipation cylinder 13 passes through the water tank 8 and is set as an opening. A heat dissipation frame 14 is fixedly connected to the top of the water tank 8. Ventilation holes 15 are symmetrically opened on the outer side of the top of the heat dissipation frame 14. A fan 16 is installed inside the heat dissipation frame 14 at the top of the water tank 8. The blowing end of the fan 16 is adapted to the ventilation hole 15.

[0033] The refrigeration mechanism includes a heat dissipation cylinder 13 installed inside the water tank 8. The top of the heat dissipation cylinder 13 passes through the water tank 8 and is set as an opening. A heat dissipation frame 14 is fixedly connected to the top of the water tank 8. Ventilation holes 15 are symmetrically opened on the outer side of the top of the heat dissipation frame 14. A fan 16 is installed inside the heat dissipation frame 14 at the top of the water tank 8. The blowing end of the fan 16 is adapted to the ventilation hole 15.

[0034] In addition, a second fan 17 is installed inside the heat dissipation frame 14 on the top of the water tank 8, and the blowing end of the second fan 17 is adapted to the ventilation hole 15.

[0035] After prolonged use, the cooling water in the water tank 8 gradually heats up. The radiator 13, made of copper, absorbs heat through its opening. The top of the radiator 13 is open, allowing the heat to be transferred to the heat sink. Simultaneously, the fan 16 is activated. The fan's blowing end is matched with the ventilation hole 15, expelling the hot air inside the heat sink frame 14 through the ventilation hole 15. This facilitates heat exchange with the outside air, increasing the heat exchange rate between the coolant and the outside air. The flowing air carries away the coolant's temperature, allowing the coolant in the water tank 8 to dissipate heat quickly and maintain its cooling effect.

[0036] During cooling, fan 217 is activated, which increases the heat exchange rate between the coolant and the outside air, further improving the heat exchange efficiency.

[0037] Reference Figure 3 and Figure 4 A mounting frame 18 is symmetrically fixedly connected to the outer side of the heat dissipation frame 14. A filter plate 19 is slidably arranged on the inner side of the mounting frame 18. A handle 20 is fixedly connected to the top of the filter plate 19. The filter plate 19 is adapted to the ventilation hole 15.

[0038] Among them, two sets of positioning frames 21 are symmetrically fixedly connected to the top of the heat dissipation frame 14. A spring 22 is fixedly connected to the inner side of the positioning frame 21. A movable plate 23 is fixedly connected to the top of the spring 22. A rotating rod 24 is fixedly connected to the top of the movable plate 23. A rotating plate 25 is rotatably connected to the top of the rotating rod 24. The bottom of the rotating plate 25 overlaps with the filter plate 19.

[0039] In addition, the inner side of the positioning frame 21 is symmetrically provided with a sliding groove 26, and the outer side of the moving plate 23 is symmetrically fixedly connected with a slider. The slider is adapted to the sliding groove 26 and the slider is slidably connected to the sliding groove 26.

[0040] When dissipating heat, first drive the handle 20 to place the filter plate 19 in the mounting frame 18. At this time, the filter is located outside the ventilation hole 15. The filter plate 19 can filter the air entering the heat dissipation frame 14, thereby reducing dust entering the heat dissipation cylinder 13 and maintaining the heat absorption effect of the heat dissipation cylinder 13.

[0041] When fixing the filter plate 19, first pull the rotating plate 25 to move the rotating rod 24 upward. The movement of the rotating rod 24 causes the moving plate 23 to move. The movement of the moving plate 23 will cause the spring 22 to stretch and generate elastic potential energy. At this time, rotate the rotating plate 25 to the top of the filter plate 19. Then release the rotating plate 25. At this time, the elastic potential energy of the spring 22 is released, causing the rotating plate 25 to move downward and abut against the top of the filter plate 19 to fix it, thereby limiting and fixing the filter plate 19 and improving the stability of the filter plate 19.

[0042] When the movable plate 23 moves, the slider and the groove 26 provide guidance for the movable plate 23, so that the movable plate 23 can maintain the correct movement trajectory when moving.

[0043] Working principle: The raw material is placed in the lower mold 6. The hydraulic telescopic rod 4 is activated, which drives the upper mold 5 to move downward and close with the lower mold 6. Pressure is applied to the raw material in the mold, and the raw material is pressed into a blank of the required shape at room temperature. After molding, the water pump 9 is activated. The water pump 9 draws the coolant in the water tank 8 through the water pipe 10 and sends it into the water pipe 11 inside the upper mold 5. The coolant flows in the water pipe 11, absorbing the heat of the upper mold 5 and the blank, and cooling the blank. The formed PTFE sheet is then removed from the mold. After long-term use, the cooling water in the water tank 8 gradually heats up. The heat sink 13 is made of copper, which allows it to absorb heat. The top of the heat sink 13 is open, so the heat in the heat sink 13 is transferred to the heat sink box. At the same time, the fan 16 is activated. The blower end of the fan 16 is matched with the ventilation hole 15, so the hot air inside the heat sink frame 14 is discharged through the ventilation hole 15, thus completing the cooling of the coolant.
