Description

Technical Field

[0001] This utility model belongs to the field of filter element mold technology, specifically, it relates to an easy demolding device for carbon fiber molded filter elements. Background Technology

[0002] Carbon fiber filter cartridges are a type of high-efficiency filtration material. Utilizing the microporous structure and adsorption properties of carbon fibers, they can effectively remove impurities, organic matter, and odors from liquids or gases. Their end caps are typically made of high-strength plastic or metal and are cast using a set of interlocking molds (moving mold and fixed mold) to ensure the precision, sealing, and structural strength of the end caps, thereby guaranteeing the overall performance of the filter cartridge.

[0003] In the existing technology, after the carbon fiber filter element end cap is cast and the moving mold is opened, the formed end cap may get stuck in the moving mold due to material shrinkage, mold surface friction, or unreasonable demolding angle design, resulting in difficulty in demolding. This problem not only increases the time for manual intervention or mechanically assisted demolding, but may also cause damage to the end cap and even affect the mold life, indirectly reducing the production efficiency of carbon fiber filter elements and increasing manufacturing costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a carbon fiber molded filter element easy demolding device that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A carbon fiber molded filter element easy demolding device includes a left support plate and a right support plate arranged opposite to each other, and further includes: a fixed mold, fixedly installed on the right support plate, wherein a telescopic device is fixedly installed on the left support plate, and a columnar support platform is fixedly installed at the telescopic end of the telescopic device, and four circumferentially distributed device blocks are installed on the support platform, the four device blocks are combined to form a moving mold that cooperates with the fixed mold; and an opening and closing component is disposed on the support platform, wherein when the device blocks move away from the fixed mold, the four device blocks simultaneously move away from the axis of the support platform.

[0007] Preferably, the opening and closing component includes four sliding grooves disposed at the shaft end of the device block, each of the four sliding grooves having a slider slidably installed therein, and a spring installed between the slider and the inner wall of the sliding groove. The four device blocks are respectively fixedly installed on the four sliders, and a triangular block with an inclined surface is fixedly connected to the left support plate, with one end of the slider facing the inclined surface.

[0008] Preferably, a horizontal tube is fixedly connected to the support platform, the end of the horizontal tube extends into the moving mold and is fixedly connected to a cross-shaped plate, and each of the four device blocks is provided with a slot that mates with the cross-shaped plate.

[0009] Furthermore, the side wall of the cross-shaped plate is provided with an exhaust hole facing the slot, and the support platform is provided with an air supply part for supplying air to the exhaust hole.

[0010] Furthermore, the air supply unit includes a telescopic airbag installed between the support platform and the left support plate. An air intake pipe and an exhaust pipe are fixedly connected to the telescopic airbag. A one-way valve is fixedly installed inside both the air intake pipe and the exhaust pipe. The end of the exhaust pipe extends into the horizontal pipe, and the exhaust hole is connected to the horizontal pipe through the inner cavity.

[0011] Furthermore, the surface of the inclined plane is fixed with equally spaced protrusions, and the protrusions are triangular in shape.

[0012] Furthermore, a pulley facing the inclined plane is rotatably mounted on the slider.

[0013] Furthermore, the outer wall of the cross-shaped plate is fitted with a sealing ring that fits against the inner wall of the slot.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0015] 1. This utility model uses a telescopic device to move the support platform away from the fixed mold. The support platform will move the four device blocks that make up the moving mold away from the fixed mold. The slider, guided by the inclined plane, moves away from the axis of the support platform. As a result, all four device blocks will move away from the axis of the support platform at the same time. A gap will be generated between adjacent device blocks, so the filter end cap in the moving mold can be removed more easily.

[0016] 2. By moving the four device blocks away from each other, the support platform will press against the telescopic airbag, and the inner cavity will blow airflow into the slot through the exhaust hole, and then discharge it from the slot into the moving mold, thereby improving the demolding efficiency of the workpiece in the moving mold.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0027] Example: Refer to Figures 1-6 A carbon fiber molded filter element easy demolding device includes a left support plate 1 and a right support plate 2 arranged opposite to each other. The left support plate 1 and the right support plate 2 are used to fix the device on the equipment or frame. The device also includes a fixed mold 3, which is fixedly installed on the right support plate 2. A telescopic device 5 is fixedly installed on the left support plate 1. The telescopic device 5 can be an electric telescopic rod or a telescopic cylinder. A columnar support platform 6 is fixedly installed at the telescopic end of the telescopic device 5. Four circumferentially distributed device blocks 4 are installed on the support platform 6. The four device blocks 4 are combined to form a moving mold that cooperates with the fixed mold 3. An opening and closing component is set on the support platform 6. When the device blocks 4 move away from the fixed mold 3, the four device blocks 4 move away from the axis of the support platform 6 at the same time.

[0028] Specifically, when demolding is required, the telescopic device 5 drives the support platform 6 away from the fixed mold 3, and the support platform 6 drives the four device blocks 4 that form the moving mold away from the fixed mold 3. At this time, the opening and closing component will cause the four device blocks 4 to move away from the axis of the support platform 6 simultaneously, and a gap will be generated between adjacent device blocks 4. Thus, the filter element end cap in the moving mold can be taken out more easily and is less likely to jam. After the workpiece is removed, the telescopic device 5 drives the moving mold to reset, and the opening and closing component will drive the four device blocks 4 to move closer to the axis of the support platform 6 at the same time and recombine to form a complete moving mold.

[0029] The opening and closing components include four sliding grooves 8 set at the shaft end of the device block 4. A slider 7 is slidably installed in each of the four sliding grooves 8. A spring 9 is installed between the slider 7 and the inner wall of the sliding groove 8. The four device blocks 4 are respectively fixedly installed on the four sliders 7. A triangular block 10 with an inclined surface 11 is fixedly connected to the left support plate 1. One end of the slider 7 faces the inclined surface 11.

[0030] Specifically, during mold opening, the support platform 6 will drive the end of the slider 7 to slide along the inclined surface 11 of the triangular block 10. The slider 7 will move away from the axis of the support platform 6 under the guidance of the inclined surface 11. As a result, the four device blocks 4 will move away from the axis of the support platform 6 at the same time, and a gap will be generated between adjacent device blocks 4. After the workpiece is removed, the telescopic device 5 will drive the moving mold to reset. The four sliders 7 will move away from the inclined surface 11. At this time, the spring 9 will drive the four sliders 7 to slide in the opposite direction in the slide groove 8 to reset, thereby driving the four device blocks 4 to move closer to the axis of the support platform 6 at the same time and reassemble into a complete moving mold.

[0031] A horizontal tube 14 is fixedly connected to the support platform 6. The end of the horizontal tube 14 extends into the moving mold and is fixedly connected to a cross-shaped plate 15. Each of the four device blocks 4 is provided with a slot 16 that mates with the cross-shaped plate 15. A sealing ring that fits against the inner wall of the slot 16 is installed on the outer wall of the cross-shaped plate 15.

[0032] Specifically, when the four device blocks 4 move away from or get closer to each other, the cross-shaped plate 15 will always seal the gap between adjacent device blocks 4 to ensure good sealing.

[0033] The side wall of the cross-shaped plate 15 is provided with an exhaust hole 17 facing the slot 16. The support platform 6 is provided with an air supply part for supplying air to the exhaust hole 17. The air supply part includes a telescopic airbag 18 installed between the support platform 6 and the left support plate 1. In practice, the telescopic airbag 18 can also be replaced by a cylinder. An air intake pipe 21 and an exhaust pipe 19 are fixedly connected to the telescopic airbag 18. A one-way valve is fixedly installed in both the air intake pipe 21 and the exhaust pipe 19. The end of the exhaust pipe 19 extends into the horizontal pipe 14. The exhaust hole 17 is connected to the horizontal pipe 14 through the inner cavity 20.

[0034] Specifically, after the four device blocks 4 move away from each other, the support platform 6 will press against the telescopic airbag 18. The telescopic airbag 18 will blow air into the horizontal pipe 14 through the exhaust pipe 19. The horizontal pipe 14 will blow air into the inner cavity 20. The inner cavity 20 will blow the airflow into the slot 16 through the exhaust hole 17, and then discharge it from the slot 16 into the moving mold, thereby improving the demolding efficiency of the workpiece in the moving mold. When the support platform 6 is reset and the telescopic airbag 18 is stretched, the telescopic airbag 18 can draw in outside air through the suction pipe 21.

[0035] The surface of the inclined plane 11 is fixedly provided with equally spaced protrusions 12. The protrusions 12 are triangular in shape. A pulley 13 facing the inclined plane 11 is rotatably mounted on the slider 7.

[0036] Specifically, when the slider 7 moves toward the inclined plane 11, the slider 7 will fix the pulley 13 on the inclined plane 11, and under the action of multiple protrusions 12, the slider 7 will vibrate, which will in turn cause the separated device block 4 to vibrate, thus further improving the demolding efficiency.

[0037] This easy demolding device for carbon fiber molded filter elements works as follows: When demolding is required, the telescopic device 5 moves the support platform 6 away from the fixed mold 3. The support platform 6 then moves the four device blocks 4, which are combined to form the moving mold, away from the fixed mold 3. It also moves the end of the slider 7 along the inclined surface 11 of the triangular block 10. Guided by the inclined surface 11, the slider 7 moves away from the axis of the support platform 6. As a result, all four device blocks 4 move away from the axis of the support platform 6 simultaneously, creating gaps between adjacent device blocks 4. This makes it easier to remove the filter element end cap from the moving mold without causing jamming. After the workpiece is removed, the telescopic device 5 moves the moving mold back to its original position. The four sliders 7 then move away from the inclined surface 11. At this time, the spring 9 moves the four sliders 7 back to their original position in the sliding groove 8. This causes the four device blocks 4 to move closer to the axis of the support platform 6 and recombine to form the complete moving mold.

[0038] When the four device blocks 4 move away from or close to each other, the cross-shaped plate 15 will always seal the gap between adjacent device blocks 4 to ensure good sealing. When the four device blocks 4 move away from each other, the support platform 6 will also press the telescopic airbag 18. The telescopic airbag 18 will blow air into the horizontal pipe 14 through the exhaust pipe 19. The horizontal pipe 14 will blow air into the inner cavity 20. The inner cavity 20 will blow the airflow into the slot 16 through the exhaust hole 17, and then discharge it into the moving mold from the slot 16, thereby improving the demolding efficiency of the workpiece in the moving mold. When the support platform 6 is reset and the telescopic airbag 18 is stretched, the telescopic airbag 18 can draw in outside air through the suction pipe 21.
