Description

Technical Field

[0001] The utility model relates to the technical field of silicone tube production and demoulding, and more specifically, it relates to a demoulding device for producing silicone tubes. Background Art

[0002] In the existing technology, the manufacturing process of silicone tubes usually includes mixing silicone rubber raw rubber with silica and other additives, and refining them evenly in a two-roll rubber mill or a closed kneader. This process requires precise control of parameters such as the ratio of raw materials, refining temperature, and time to ensure that the performance of the final product meets industry standards. After refining, the silicone tube needs to be demoulded from the mold for subsequent processing and testing.

[0003] However, there are some problems with the existing demoulding technologies. Firstly, a large amount of manpower is required in the manual demoulding process, which not only increases production costs, but also easily causes damage to the silicone tubes due to the limitations of manual operation, affecting the yield. In addition, the speed of manual demoulding is slow and cannot meet the efficiency requirements of large-scale production.

[0004] Secondly, the clamping method of silicone tubes during demoulding in the existing technology is often not reasonable. Usually, it is directly fixed manually or the staff borrows other tools for fixation. The operation is usually cumbersome, and it is easy to make mistakes, requiring too much manpower, time-consuming and laborious, and slowing down production efficiency.

[0005] In addition, some devices in the existing technology use water flow or air flow to be sprayed into the gap between the silicone tube and the mold (solid tube) to complete the demoulding work. This method can reduce the direct contact with the silicone tube to a certain extent and reduce the risk of damage. However, the internal structure of the existing pipeline is simple and cannot flexibly adjust the output flow rate of water flow or air flow according to actual needs, which limits the flexibility and controllability of the demoulding effect, and may lead to incomplete demoulding or over-demoulding, affecting product quality and production efficiency.

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the present utility model provides a demolding device for producing silicone tubes, which has the following beneficial effects:

[0019] 1. Through the combination of the first cylinder, the first piston rod, the connecting sleeve and the spray pipe, the design of the demolding device realizes the efficient demolding of the silicone tube. The first cylinder provides power to make the spray pipe enter the silicone tube, and the compressed gas or water flow is conveyed into the silicone tube through the spray pipe to separate it from the mold. This design not only improves the demolding efficiency, but also reduces manual operation and labor intensity.

[0020] 2. Through the combination of components such as the clamping block and the sliding groove, the design of the clamping device realizes the stable clamping of the silicone tube. The second cylinder provides power, and the limiting block is driven to slide in the limiting groove through the second piston rod and the connecting frame, so that the clamping block moves along the sliding groove, thereby stably clamping the silicone tube.

[0021] 3. Through the combination of components such as the sliding frame, the flow blocking piece, the positioning rod, the pushing spring, the positioning groove, the fixing frame, the adjusting sleeve, the annular groove, the screw rod, the screw sleeve and the adjusting pipe, the design of the adjusting device realizes the flexible adjustment of the passing speed of the water flow or air flow. The rotation of the adjusting sleeve makes the positioning rod disengage from the positioning groove and slide along the annular groove, and then drives the sliding frame to move through the cooperation of the screw rod and the screw sleeve, thereby changing the gap of the flow blocking piece, so as to limit the speed of the water flow or air flow. This design not only improves the adjustment flexibility, but also improves the demolding adaptability and accuracy. Description of the drawings

[0031] Please refer to Figures 1-5 , a demolding device for producing silicone tubes, including a mounting base 1, a demolding device is provided on the mounting base 1, the demolding device includes a first cylinder 2, a first piston rod 3, a connecting sleeve 4 and a spray pipe 5, the first cylinder 2 is detachably installed on one side of the mounting base 1, one end of the first piston rod 3 is connected to the output end of the first cylinder 2, the other end of the first piston rod 3 is connected to the connecting sleeve 4, the spray pipe 5 is detachably installed on one side of the connecting sleeve 4, one end of the spray pipe 5 is connected with an adjusting device, the adjusting device includes a sliding frame 6, a flow blocking piece 7, a positioning rod 8, a push spring 9, a positioning groove 10, a fixing frame 11, an adjusting sleeve 12, an annular groove 13, a screw 14, a screw sleeve 15 and an adjusting pipe 16, the sliding frame 6 is slidably arranged in the adjusting pipe 16, both ends of the flow blocking piece 7 are respectively connected to the fixing frame 11 and the sliding frame 6, the positioning rod 8 is movably installed outside the adjusting pipe 16, the push spring 9 is movably sleeved outside the positioning rod 8, the positioning groove 10 is opened in the annular groove 13, the fixing frame 11 is fixedly connected to the inner side of the adjusting sleeve 12, the adjusting sleeve 12 is movably arranged on one side of the adjusting pipe 16, the annular groove 13 is opened on one side of the adjusting sleeve 12, the screw 14 is fixedly connected to one side of the fixing frame 11, the screw sleeve 15 is arranged inside the sliding frame 6, the adjusting pipe 16 is fixedly connected to one end of the spray pipe 5, and a clamping device is arranged on the other side of the mounting base 1.

[0032] A sliding groove 17 is provided inside the adjusting pipe 16, and a sliding block 18 is provided outside the sliding frame 6. The sliding block 18 is slidably arranged in the sliding groove 17.

[0033] A plurality of positioning grooves 10 are provided, and the plurality of positioning grooves 10 are evenly arranged in the annular groove 13.

[0034] The screw sleeve 15 is movably sleeved outside the screw rod 14 through threads.

[0035] In this embodiment, when the device is needed to demold the silicone tube, first hold the silicone tube properly, then open the first cylinder 2. The first cylinder 2 drives the output end of the nozzle 5 to extend into the silicone tube through the connecting sleeve 4 connected to the output end. Then place the whole device into an external water tank. Then, through an external conveying device, compressed gas or water flow is conveyed to the nozzle 5 and then conveyed into the silicone tube through the nozzle 5. Then the compressed air or compressed water flow enters the gap between the silicone tube and the mold. When the pressure is too high, it will eject the mold out of the silicone tube, thus realizing the demolding work. When it is necessary to adjust the flow rate in the adjusting pipe 16 according to requirements, rotate the adjusting sleeve 12 in the corresponding direction. Due to the rounded corner structure design at the edge of the positioning rod 8 and the positioning groove 10, when the adjusting sleeve 12 drives the positioning groove 10 to rotate, the side wall of the positioning groove 10 will squeeze the positioning rod 8, so that one end of the positioning rod 8 disengages from the positioning groove 10. At the same time, the push spring 9 arranged outside the positioning rod 8 will be compressed. Then the positioning rod 8 will slide into the annular groove 13. At the same time, the adjusting sleeve 12 will drive the fixed frame 11 arranged inside to rotate, so that the fixed frame 11 drives the screw rod 14 to rotate. Since the screw sleeve 15 is movably sleeved outside the screw rod 14 through threads, and the sliding block 18 and the sliding groove 17 limit the sliding frame 6, the sliding frame 6 and the screw sleeve 15 will not rotate. Then the screw sleeve 15 will slide along the screw rod 14. At the same time, the sliding frame 6 will drive the sliding block 18 to slide along the sliding groove 17. Then the distance between the sliding frame 6 and the fixed frame 11 will change, so that the gap of the flow blocking piece 7 will change, thereby restricting the speed of the water flow or air flow passing through. After adjustment, stop rotating the adjusting sleeve 12 so that the positioning rod 8 corresponds to the position of the corresponding positioning groove 10. Then the push spring 9 resets and pushes the positioning rod 8 to engage into the corresponding positioning groove 10, thus preventing the adjusting sleeve 12 from rotating easily.

[0036] Please refer to Figures 1-3 , as an implementation manner of the clamping device: The clamping device includes a clamping block 19 and a sliding groove 20. The sliding groove 20 is opened on the inner side of the mounting seat 1, and the clamping block 19 is slidably mounted in the sliding groove 20.

[0037] A limiting groove 21 is formed on one side of the clamping block 19. A limiting block 22 is arranged in the limiting groove 21. An inclined groove 23 is formed on the limiting block 22. Guide posts 24 are arranged on both sides of the clamping block 19, and the guide posts 24 are slidably installed in the inclined groove 23.

[0038] Transverse grooves 25 are formed on both sides of the mounting seat 1, and the guide posts 24 are slidably located in the transverse grooves 25.

[0039] A second air cylinder 26 is arranged on one side of the mounting seat 1. A second piston rod 27 is arranged at the output end of the second air cylinder 26. A connecting frame 28 is arranged at the other end of the second piston rod 27, and the connecting frame 28 is connected to the limiting block 22.

[0040] More specifically, when it is necessary to clamp the silica gel tube, first open the second air cylinder 26 installed on one side of the mounting seat 1. The second air cylinder 26 drives the limiting block 22 to slide in the limiting groove 21 through the second piston rod 27. Due to the special structural design of the inclined groove 23 and the limitation of the transverse groove 25 on the guide post 24, the guide post 24 will slide along the transverse groove 25, and the two clamping blocks 19 will slide relatively along the sliding groove 20 to both sides. Then place the silica gel tube between the two clamping blocks 19. Then make the second air cylinder 26 run in the reverse direction, so that the second air cylinder 26 drives the second piston rod 27 to contract, thereby making the clamping block 19 reset. Then the two clamping blocks 19 will stably clamp the inner silica gel tube.

[0041] In summary, when the overall device is in use or operation: when it is necessary to demold the silicone tube using the device, first clamp the silicone tube reasonably, then open the first cylinder 2. The first cylinder 2 drives the output end of the nozzle 5 to extend into the silicone tube through the connecting sleeve 4 connected to the output end. Then place the entire device into an external water tank. Then, through an external conveying device, compressed gas or water flow is conveyed to the nozzle 5 and then through the nozzle 5 into the silicone tube. Then, the compressed air or compressed water flow enters the gap between the silicone tube and the mold. When the pressure is too high, it will eject the mold out of the silicone tube, thus realizing the demolding work. When it is necessary to adjust the flow rate in the pipe 16 according to requirements, rotate the adjusting sleeve 12 in the corresponding direction. Due to the rounded corner structure design at the edges of the positioning rod 8 and the positioning groove 10, when the adjusting sleeve 12 drives the positioning groove 10 to rotate, the side wall of the positioning groove 10 will squeeze the positioning rod 8, causing one end of the positioning rod 8 to disengage from the positioning groove 10. At the same time, the push spring 9 arranged outside the positioning rod 8 will be compressed. Then the positioning rod 8 will slide into the annular groove 13. At the same time, the adjusting sleeve 12 will drive the fixing frame 11 arranged inside to rotate, causing the fixing frame 11 to drive the screw rod 14 to rotate. Since the nut sleeve 15 is movably sleeved outside the screw rod 14 through threads, and the sliding block 18 and the sliding groove 17 limit the sliding frame 6, the sliding frame 6 and the nut sleeve 15 will not rotate. Then the nut sleeve 15 will slide along the screw rod 14. At the same time, the sliding frame 6 will drive the sliding block 18 to slide along the sliding groove 17. Then the distance between the sliding frame 6 and the fixing frame 11 will change, thereby changing the gap of the flow blocking piece 7, and further achieving the limitation of the speed of the water flow or air flow passing through. After adjustment, stop rotating the adjusting sleeve 12 so that the positioning rod 8 corresponds to the position of the corresponding positioning groove 10. Then the push spring 9 resets and pushes the positioning rod 8 to engage into the corresponding positioning groove 10, thus preventing the adjusting sleeve 12 from rotating easily.

[0042] When it is necessary to clamp the silicone tube, first open the second cylinder 26 installed on one side of the mounting seat 1. The second cylinder 26 drives the limiting block 22 to slide in the limiting groove 21 through the second piston rod 27. Due to the special structure design of the inclined groove 23 and the limitation of the guiding column 24 by the transverse groove 25, the guiding column 24 will slide along the transverse groove 25, and the two clamping blocks 19 will slide relatively along the sliding groove 20 to both sides. Then place the silicone tube between the two clamping blocks 19. Then make the second cylinder 26 run in the reverse direction, causing the second cylinder 26 to drive the second piston rod 27 to contract, so that the clamping blocks 19 are reset. Then the two clamping blocks 19 will stably clamp the inner silicone tube.

[0043] Among all the solutions mentioned above, for the connection between two components, welding, the connection with bolts and nuts, bolt or screw connection, or other well-known connection methods can be selected according to the actual situation, which will not be elaborated one by one here. For those mentioned above that involve fixed connection, welding is preferably considered. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that these embodiments can be subject to various changes, modifications, substitutions, and variations without departing from the principle and spirit of the present invention.
