Description

Technical Field

[0001] This utility model relates to the field of insulating film processing technology, specifically to an insulating film hot pressing mold. Background Technology

[0002] In the modern electronics industry and electrical insulation material manufacturing field, insulating film, as a key component material, is widely used in the insulation protection of capacitors, transformers, motors, cables and various electronic devices. The performance of insulating film not only requires good electrical insulation, mechanical strength and heat resistance, but also stable dimensional accuracy and surface quality to meet the strict requirements of different application scenarios. In the traditional production method of insulating film, hot pressing is a common and effective processing method. This method applies pressure to the preheated composite material through a mold and holds it at a certain temperature for a period of time, so that the material molecules cross-link or melt bond, thereby achieving solidification and molding.

[0003] However, traditional hot press molds often face many challenges in the demolding process. On the one hand, the insulating film material may generate high adhesion during the hot pressing process, making demolding difficult and easily causing product damage or mold wear. On the other hand, traditional demolding methods such as mechanical ejection or manual peeling are not only inefficient, but may also introduce new defects due to improper operation, affecting product quality. Therefore, it is necessary to design an insulating film hot press mold to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a hot pressing mold for insulating film to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an insulating film hot pressing mold, comprising a lower mold and an upper mold, wherein the upper mold is movably disposed on top of the lower mold, and a clamping plate is installed at the bottom of the upper mold and the clamping plate can be engaged inside the lower mold. The lower mold and the clamping plate are respectively provided with cavities inside, and multiple sets of movable grooves are respectively provided on one side of multiple sets of cavities.

[0006] Each of the multiple sets of movable slots is connected to a reset assembly between itself and the circular cover plate. An air pump is provided on one side of the lower mold and the top of the upper mold. One end of each of the two sets of air pumps is connected to an air supply pipe, and the two sets of air supply pipes are respectively connected to the cavity.

[0007] Preferably, the reset assembly includes a slide groove, a movable plate, and a spring. Each set of two slide grooves is circumferentially formed inside the movable groove. Multiple sets of movable plates are slidably connected inside the support rod, and the tops of each set of two movable plates are connected to the bottom of the circular cover plate. Multiple sets of springs are connected between one side of the slide groove and the movable plate.

[0008] Preferably, support rods are installed inside the multiple sets of sliding grooves, the movable plate is slidably connected to the outside of the support rods, and the spring is located on the outside of the support rods.

[0009] Preferably, a support frame is installed on one side of the lower mold, and an electric telescopic rod is installed at the bottom end of the support frame. The extension end of the electric telescopic rod is connected to the top of the upper mold.

[0010] Preferably, support plates are installed on both sides of the lower mold, and limit grooves are opened in the interior of the two sets of support plates. The two ends of the upper mold are slidably connected between the two sets of limit grooves.

[0011] Preferably, the lower mold is equipped with stabilizing legs at the four corners of its bottom, and the four sets of stabilizing legs support the lower mold.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By pouring the composite material into the lower mold, moving the upper mold so that the clamping plate engages inside the lower mold to compress the composite material, allowing it to cool and solidify. During demolding, while resetting the upper mold, two sets of air pumps are turned on.

[0014] 2. A spring is installed between the moving plate and the slide. Under normal conditions, the spring pulls the moving plate so that the circular cover plate is located at the top of the movable groove. When the circular cover plate receives air pressure and moves upward, the spring is in a stretched state.

Example

[0020] Please refer to Figure 1-3 As shown, this utility model provides an insulating film hot pressing mold, including a lower mold 1 and an upper mold 13. The upper mold 13 is movably disposed on the top of the lower mold 1. A clamping plate 14 is installed at the bottom of the upper mold 13 and the clamping plate 14 can be locked inside the lower mold 1. The lower mold 1 and the clamping plate 14 are respectively provided with cavities 2. Multiple sets of movable grooves 3 are respectively provided on one side of multiple sets of cavities 2. The top of multiple sets of movable grooves 3 are respectively slidably sealed with circular cover plates 7.

[0021] Multiple sets of movable slots 3 are connected to the circular cover plate 7 respectively with reset components. One side of the lower mold 1 and the top of the upper mold 13 are respectively provided with air pumps 9. One end of each set of air pumps 9 is connected to an air supply pipe 10 and the two sets of air supply pipes 10 are respectively connected to the cavity 2.

[0022] Specifically, by pouring the composite material into the lower mold 1, moving the upper mold 13 so that the clamping plate 14 engages inside the lower mold 1 to compress the composite material and cool it for molding, during demolding, while resetting the upper mold 5, two sets of air pumps 9 are turned on. The two sets of air pumps 9 deliver air to the cavity 2 set inside the lower mold 1 and the clamping plate 14 through the connected air supply pipe 10, and then discharge the air through the movable groove 3 opened on one side of the cavity 2. The circular cover plate 7 that seals and slides at the top of the movable groove 3 is lifted up to push out the molded insulating film, thus completing the demolding process.

[0023] The reset assembly includes a slide 4, a movable plate 6, and a spring 8. Each pair of slides 4 are circumferentially formed inside the movable groove 3. Multiple movable plates 6 are slidably connected inside the support rod 5, and the tops of each pair of movable plates 6 are connected to the bottom of the circular cover plate 7. Multiple springs 8 are connected between one side of the slide 4 and the movable plate 6. Under normal conditions, the springs 8, which are set between the movable plate 6 and the slide 4, pull the movable plate 6, so that the circular cover plate 7 is located at the top of the movable groove 3. When the circular cover plate 7 receives air pressure and moves upward, the springs 8 are in a stretched state. When the air pressure disappears, the springs 8 pull the movable plate 6 and the circular cover plate 7 back to reset.

[0024] Among them: support rods 5 are installed inside the multiple sets of sliding grooves 4 respectively, the movable plate 6 is slidably connected to the outside of the support rods 5 and the spring 8 is located on the outside of the support rods 5. The movable plate 6 slides on the outside of the support rods 5 and the spring 8 is stretched on the outside of the support rods 5 to prevent the spring 8 from deviating.

[0025] Wherein: a support frame 11 is installed on one side of the lower mold 1, and an electric telescopic rod 12 is installed at the bottom end of the support frame 11. The extension end of the electric telescopic rod 12 is connected to the top of the upper mold 13.

[0026] Among them: support plates 15 are installed on both sides of the lower mold 1, and limit grooves 16 are opened in the interior of the two sets of support plates 15 respectively. The two ends of the upper mold 13 are slidably connected between the two sets of limit grooves 16. When the upper mold 13 moves, it slides inside the two sets of support plates 15, thereby improving the stability of the upper mold 13 when it moves.

[0027] Among them, the bottom four corners of the lower mold 1 are respectively equipped with stabilizing legs 17, and the four sets of stabilizing legs 17 support the lower mold 1. The stability of the lower mold 1 during the processing of insulating film is improved by the stabilizing legs 17 installed at the bottom of the lower mold 1.

[0028] Working Principle: This utility model provides a hot pressing mold for insulating film. The composite material is poured into the lower mold 1. The electric telescopic rod 12 is activated to push the upper mold 13 downward, so that the clamping plate 14 engages inside the lower mold 1 to compress the composite material and cool and form it. During demolding, the upper mold 5 is reset, and two sets of air pumps 9 are activated. The two sets of air pumps 9 deliver air to the cavity 2 set inside the lower mold 1 and the clamping plate 14 through the connected air supply pipe 10. The air is then discharged through the movable groove 3 opened on one side of the cavity 2, and the circular cover plate 7 that is sealed and sliding at the top of the movable groove 3 is lifted to push out the formed insulating film, completing the demolding process. A spring 8 is set between the moving plate 6 and the slide 4. Under normal conditions, the spring 8 pulls the moving plate 6 so that the circular cover plate 7 is located at the top of the movable groove 3. When the circular cover plate 7 receives air pressure and moves upward, the spring 8 is in a stretched state. When the air pressure disappears, the spring 8 pulls the moving plate 6 and the circular cover plate 7 back to their original positions.
