Description

Technical Field

[0001] This utility model relates to the field of carat tube technology, specifically a carat tube demolding device. Background Technology

[0002] A Krah tube is a small transistor made using a ceramic thin film. Unlike traditional silicon-based integrated circuits, Krah tubes use ceramic materials, which allows them to achieve higher frequencies, better thermal stability, and longer lifespans.

[0003] However, in the current technology, when demolding the Krah tube, a clamping structure is used to fix one end of the tube and pull the tube to slide off the mold. However, during the pulling process, the tube and the mold will stick to a certain extent during production, so forcibly pulling will cause damage to the tube. Utility Model Content

[0004] The purpose of this invention is to provide a demolding device for kraft tubes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A kraft tube demolding device includes a base frame, a positioning frame at the top of the base frame, and an auxiliary component for assisting in demolding the kraft tube inside the positioning frame. The auxiliary component includes a mounting frame inside the positioning frame, a support plate at the front end of the mounting frame, a clamping plate on one side of the support plate, a connecting rod near the mounting frame on the support plate, a piston at the other end of the connecting rod, a cavity near the support plate on the mounting frame, a spring and an air chamber inside the cavity, a pressure sensor on the inner wall of the air chamber, and two annular grooves inside the support plate, each containing an eccentric wheel.

[0007] As a preferred embodiment of this utility model, the positioning frame is connected to the top of the base frame by bolts, the interior of the positioning frame has an arc-shaped structure and corresponds to the kraft tube, the mounting frame is located inside the positioning frame and is slidably connected to the inner wall of the positioning frame by a slide rail.

[0008] As a preferred embodiment of this utility model, the support plate is located on one side of the mounting frame, the clamping plate is slidably connected to the inner wall of the support plate via a slide rail, the clamping plate has an arc structure, and it is clamped to the lauryl tube by sliding on the support plate.

[0009] As a preferred embodiment of this utility model, one end of the connecting rod is connected to the outer wall of the support plate by bolts, and the other end extends into the mounting frame, penetrates the cavity and extends into the air chamber, and is connected to the piston by bolts. The piston is located in the air chamber and is slidably connected to the inner wall of the air chamber.

[0010] As a preferred embodiment of this utility model, both ends of the spring are connected to the inner wall of the cavity and the outer wall of the connecting rod respectively by welding. The pressure sensor is located inside the air chamber and detects the pressure inside the air chamber when the connecting rod slides. The pressure sensor is electrically connected to the sliding mechanism at the bottom of the mounting frame.

[0011] As a preferred embodiment of this utility model, the two annular grooves are located in the two sets of clamping plate areas within the support plate, and the eccentric wheel is located within the annular groove and is rotatably connected to the inner wall of the annular groove via a connecting shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In response to the problems mentioned in the background art, this application adopts an auxiliary component. The clamping plate on the support plate can clamp the kraft tube on the mold, and the mounting frame slides and retracts on the positioning frame to drive the kraft tube to slide and separate from the mold.

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the embodiments of this utility model.

[0020] Example

[0021] Please see Figure 1-4 This utility model provides a technical solution: a kraft tube demolding device, including a base frame 1, a positioning frame 2 on the top of the base frame 1, the positioning frame 2 being used to position the angle of the kraft tube during demolding, and an auxiliary component inside the positioning frame 2 for assisting in the demolding of the kraft tube, the auxiliary component including a mounting frame 3 disposed inside the positioning frame 2, a support plate 4 disposed at the front end of the mounting frame 3, and a clamping plate 401 disposed on one side of the support plate 4, the clamping plate 401 being able to slide on the support plate 4 and clamp the kraft tube on the mold. The support plate 4 is fixed, and a connecting rod 5 is provided on the side near the mounting frame 3 to connect the support plate 4 to the mounting frame 3. A piston 501 is provided at the other end of the connecting rod 5. The piston 501 is located inside the gas chamber 7, which is filled with high-pressure gas. When the support plate 4 extends and retracts between the support plate 4 and the mounting frame 3, the connecting rod 5 drives the piston 501 to extend and retract within the gas chamber 7. When the piston 501 slides, it compresses the gas inside the gas chamber 7, thereby increasing the pressure inside the gas chamber 7. A cavity 6 is provided on the side of the mounting frame 3 near the support plate 4 to accommodate the connecting rod 5. The positioning mechanism restricts the angle of the support plate 4. A spring 601 and an air chamber 7 are installed inside the cavity 6. The spring 601 supports the connecting rod 5 and the support plate 4, and pushes the connecting rod 5 to cause the support plate 4 to retract towards the cavity 6 and approach the mounting frame 3. A pressure sensor 701 is installed on the inner wall of the air chamber 7 to detect the air pressure inside. When the mounting frame 3 moves and retracts within the positioning frame 2, the support plate 4 and clamping plate 401 on the other side drive the kraft tube to retract (and when the kraft tube adheres to the mold, increasing demolding resistance). The support plate 4 will be pulled away from the mounting frame 3 for buffering. At the same time, the connecting rod 5 on one side of the support plate 4 drives the piston 501 to move in the air chamber 7 to compress the gas in the air chamber 7 and increase the pressure. When the air pressure increases to a specified value, a reminder is given and the mounting frame 3 is controlled to stop moving. The support plate 4 is provided with two annular grooves 8. Each of the two annular grooves 8 is provided with an eccentric wheel 801. When the eccentric wheel 801 rotates, it can generate vibration and transmit it to the kraft tube through the clamping plate 401. The vibration can separate the kraft tube from the mold and assist in demolding.

[0022] In this embodiment, all electrical components are controlled by a conventional controller.

[0023] For an example, please refer to... Figure 1-4The positioning frame 2 is bolted to the top of the base frame 1. The interior of the positioning frame 2 has an arc-shaped structure and corresponds to the kraft tube. The mounting frame 3 is located inside the positioning frame 2 and is slidably connected to the inner wall of the positioning frame 2 via a slide rail. The support plate 4 is located on one side of the mounting frame 3. The clamping plate 401 is slidably connected to the inner wall of the support plate 4 via a slide rail. The clamping plate 401 has an arc-shaped structure and clamps the kraft tube by sliding on the support plate 4. One end of the connecting rod 5 is bolted to the outer wall of the support plate 4, and the other end extends into the mounting frame 3, through the cavity 6, and into the air chamber 7. The piston 501 is connected to the cylinder 7 by bolts. The piston 501 is located inside the cylinder 7 and is slidably connected to the inner wall of the cylinder 7. The two ends of the spring 601 are welded to the inner wall of the cavity 6 and the outer wall of the connecting rod 5, respectively. The pressure sensor 701 is located inside the cylinder 7 and detects the pressure inside the cylinder 7 when the connecting rod 5 slides. The pressure sensor 701 is electrically connected to the sliding mechanism at the bottom of the mounting frame 3. The two annular grooves 8 are located in the two sets of clamping plates 401 areas inside the support plate 4, respectively. The eccentric wheel 801 is located inside the annular groove 8 and is rotatably connected to the inner wall of the annular groove 8 through a connecting shaft. In operation, the mounting frame 3 is first moved to one end of the positioning frame 2 so that the clamping plate 401 on one side of the support plate 4 abuts against and clamps the kraft tube. Then, the mounting frame 3 is moved and retracted within the positioning frame 2 by the PLC controller, and the kraft tube is moved and demolded by the support plate 4 and the clamping plate 401. When the kraft tube sticks to the mold, increasing the demolding resistance, the support plate 4 is pulled away from the mounting frame 3. At the same time, the connecting rod 5 at the other end of the support plate 4 extends and retracts with the mounting frame 3, causing the support plate 4 to move away from the mounting frame 3 for buffering. The other end of the connecting rod 5 drives the piston 501 to retract and compress the air in the air chamber 7. When the air pressure is compressed to a specified value, it is detected by the pressure sensor 701, and the mounting frame 3 is stopped. Then, the eccentric wheel 801 is controlled to rotate in the annular groove 8 by the PLC controller and generate vibration. The vibration is transmitted to the kraft tube through the clamping plate 401 to assist in demolding.

[0024] The working process of this utility model is as follows: In use, the installation frame 3 is first moved to one end of the positioning frame 2 so that the clamping plate 401 on one side of the support plate 4 abuts against and clamps the kraft tube. Then, the installation frame 3 is moved and retracted within the positioning frame 2 by the PLC controller, and the kraft tube is moved and demolded by the support plate 4 and the clamping plate 401. When the kraft tube sticks to the mold, increasing the demolding resistance, the support plate 4 is pulled away from the installation frame 3. At the same time, the connecting rod 5 at the other end of the support plate 4 extends and retracts with the installation frame 3, so that the support plate 4 is moved away from the installation frame 3 for buffering. The other end of the connecting rod 5 drives the piston 501 to retract and compress the air in the air chamber 7. When the air pressure is compressed to a specified value, it is detected by the pressure sensor 701 and the installation frame 3 is stopped. Then, the eccentric wheel 801 is controlled to rotate in the annular groove 8 by the PLC controller and generate vibration. The vibration is transmitted to the kraft tube through the clamping plate 401 to assist in demolding. This invention provides a buffer during the demolding of the Krah tube and induces vibration in the Krah tube during the demolding process to assist in the separation of the Krah tube from the mold, thereby improving the demolding effect and ensuring the integrity of the Krah tube.
