Description

Technical Field

[0001] The present invention relates to the technical field of carbon fiber processing equipment, and in particular to a carbon fiber profile processing mold which is easy to demould. Background Art

[0002] Carbon fiber composite materials, as a new type of structural material, are one of the ideal materials for building high-performance products. Carbon fiber composite materials have excellent physical properties, good specific strength, high specific stiffness, and their mechanical properties can be controlled and changed through design. Previous robotic arms were made of conventional metal materials, and environmental factors had a greater impact on the accuracy of robotic arms. Carbon fiber composite materials have more design flexibility and are materials that can have the desired physical properties. In the existing technology, when processing carbon fiber tubes, carbon fiber prepreg is generally laid and wound on the outer wall of the core mold, and then hot pressing, core removal, surface treatment, processing, assembly, testing and cleaning are carried out in sequence to obtain carbon fiber tubes. However, when the core mold in the existing technology is used to demold the carbon fiber tube, it is difficult to demold due to a series of hot pressing operations in the early stage. Therefore, there is an urgent need for a carbon fiber profile processing mold that is easy to demold. Summary of the Invention

[0003] The purpose of the present invention is to provide a carbon fiber profile processing mold with a simple structure, reasonable design, easy use and easy demoulding to address the defects and shortcomings of the existing technology, which can solve the technical problems in the existing technology.

[0004] To achieve the above object, the present invention adopts the following technical solution: it comprises a core mold body, wherein the core mold body is formed by a first tube body and a second tube body being sleeved together, a flange is provided at the end of the first tube body, and the flange is movably inserted in the middle of the second tube body;

[0005] It also contains:

[0006] A locking mechanism, one end of which is arranged in the middle of the first tube body, and the other end of which is arranged in the middle of the second tube body;

[0007] There are two adjusting mechanisms, which are respectively connected to the left and right sides of the locking mechanism, and the two adjusting mechanisms are respectively provided on the end surfaces of the first tube body and the second tube body;

[0008] The auxiliary demoulding mechanism is arranged inside the first tube body.

[0009] As a further improvement of the present invention, the adjustment mechanism comprises:

[0010] The sleeves are movably mounted on the end faces of the first and second tube bodies through bearings, and a guide groove is provided in the middle of the inner end of the sleeve; a mounting ring is fixedly mounted on the outer end of the sleeve;

[0011] A threaded rod, wherein a guide bar is provided on the outer side wall of one end of the threaded rod, the threaded rod is movably inserted into the guide groove inside the sleeve through the guide bar, and the other end of the threaded rod is rotated through the middle of the fixed block through a thread, and the fixed blocks are fixedly provided inside the No. 1 tube body and the No. 2 tube body respectively.

[0012] Through the above technical solution design, the installation of the core removal device as a whole is facilitated by the installation ring. The sleeve is rotated, and the sleeve drives the threaded rod to rotate through the guide groove and the guide bar. Since the threaded rod is rotated through the middle of the fixed block through the thread, the threaded rod moves to one side when it rotates.

[0013] As a further improvement of the present invention, a cross groove is provided on the outer end surface of the threaded rod.

[0014] Through the above technical solution design, the threaded rod is rotationally adjusted through the cross groove.

[0016] A locking column, which is fixedly arranged at the end of the threaded rod on the left side and movably penetrates the middle of the flange. The locking column is composed of several stacked and fixed cones;

[0018] The moving block is arranged in the middle of the two adjusting blocks, and the cross-section of the moving block is an isosceles trapezoidal structure. Guide blocks are symmetrically fixed on the upper and lower side walls of the adjusting block, and the guide blocks are slidably embedded in the inside of the adjusting groove; the end of the threaded rod on the right side is rotatably connected to the right side wall of the moving block through a bearing.

[0019] Through the above technical solution design, when the No. 1 tube body and the No. 2 tube body are docked, the threaded rod on the left drives the locking column to pass through the end of the No. 2 tube body, and then extends between the two limit plates. Then the threaded rod on the right is rotated, and the threaded rod on the right drives the moving block to move in the middle of the two adjustment blocks, and drives the two adjustment blocks to move relative to each other through the guide block and the adjustment slot. The distance between the limit plates is reduced, and the locking column is clamped in the middle of the limit plates, thereby fixing the No. 1 tube body and the No. 2 tube body.

[0020] As a further improvement of the present invention, a compression spring is sleeved on the outer side of the telescopic rod, and both ends of the compression spring are fixedly connected to the limit plate and the inner side wall of the second tube body respectively.

[0023] Through the above technical solution design, the movement of the locking column is guided by the setting of the guide ring, so as to prevent the locking column from extending too long into the second tube body and causing skew.

[0024] As a further improvement of the present invention, the auxiliary demoulding mechanism comprises:

[0025] There are several sealing plates, each of which is movably disposed in a telescopic slot extending through the first tube body and the side wall of the fixed block on the left side; a return spring is fixedly disposed on the bottom surface of each sealing plate, the other end of which is fixedly disposed on the side wall of the telescopic slot; an air duct is disposed on the side wall of the fixed block, and the interior of the first tube body is connected to the interior of the telescopic slot through the air duct;

[0026] A movable ring is movably arranged inside the No. 1 tube body, with the surrounding walls of the movable ring contacting the inner wall of the No. 1 tube body, and the movable ring is movably sleeved on the outer side of the left threaded rod; a plurality of steel wire ropes are fixedly connected to the movable ring, and the other ends of the plurality of steel wire ropes are movably passed through the side wall of the fixed block and the telescopic slot, and are fixedly connected to the bottom of the sealing plate;

[0027] An air nozzle, the air nozzle is fixedly connected and arranged on the end surface of the first tube body, and the air nozzle is connected to an external air source;

[0028] An adjusting screw, wherein the adjusting screw is threadably rotated through the side wall of the end face of the first tube body and is rotatably connected to the bottom of the movable ring via a bearing;

[0029] The limiting ring is fixedly arranged inside the No. 1 tube body on the right side of the moving ring, and the limiting ring and the moving ring are set to limit each other.

[0030] Through the above technical solution design, when the carbon fiber tube is demolded and unloaded, the adjusting screw is rotated, and the adjusting screw drives the movable plate to move to the left, and the sealing plate moves toward the inside of the telescopic slot. The reset spring is compressed until the air duct is exposed on the outside of the sealing plate, and the air nozzle is connected to the external air source. The high-pressure airflow enters the interior of the No. 1 tube body from the air nozzle, and enters between the carbon fiber tube and the outer wall of the No. 1 tube body from the air duct, thereby assisting in separating the carbon fiber tube from the outer wall of the No. 1 tube body.

[0031] As a further improvement of the present invention, the outer end of the adjusting screw is fixedly connected to a plum blossom hand screw.

[0032] Through the above technical solution design, the adjustment screw can be adjusted more conveniently through the plum blossom hand-tightening setting.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. The core mold body is made of a No. 1 tube body and a No. 2 tube body. When demoulding, the No. 1 tube body and the No. 2 tube body are disassembled through the adjustment mechanism and the locking mechanism, and then the No. 1 tube body and the No. 2 tube body are pulled out from the inside of the carbon fiber tube from two opposite directions, which reduces the length of the core mold to be pulled out and makes demoulding more convenient.

[0035] 2. By setting up the auxiliary demoulding mechanism, high-pressure airflow is injected between the inner wall of the carbon fiber tube and the outer wall of the No. 1 tube body, so that the carbon fiber tube is separated from the outer wall of the No. 1 tube body, making demoulding more convenient.

[0057] The locking column 4-1 is fixedly welded to the end of the threaded rod 2-4 on the left side, and the locking column 4-1 is movably inserted into the middle of the flange 1-3. The locking column 4-1 is composed of several stacked and fixed cones;

[0058] The limiting plates 4-2 are two and are symmetrically arranged on the upper and lower sides of the interior of the No. 2 tube body 1-2. The inner tooth grooves of the limiting plates 4-2 are movably clamped with the outer wall of the locking column 4-1, and the tooth groove shape of the inner wall of the limiting plates 4-2 is matched with the truncated cone shape; a telescopic rod 4-3 is fixedly provided on the side wall of the limiting plate 4-2 by bolts, and the other end of the telescopic rod 4-3 is fixedly provided on the inner wall of the No. 2 tube body 1-2; an adjusting block 4-4 is fixedly provided on the end of the limiting plate 4-2 by bolts, and an adjusting groove 4-5 is provided inside the side wall of the adjusting block 4-4; a compression spring 5 is sleeved on the outer side of the telescopic rod 4-3, and the two ends of the compression spring 5 are fixedly connected to the limiting plate 4-2 and the inner wall of the No. 2 tube body 1-2 by bolts; the provision of the compression spring 5 increases the stability of the limiting plate 4-2 against the locking column 4-1;

[0059] A guide ring 6 is fixedly welded inside the pipe opening of the second pipe body 1-2 on the left side of the limit plate 4-2, and the locking column 4-1 is movably inserted into the middle of the guide ring 6; the guide ring 6 guides the movement of the locking column 4-1 to prevent the locking column 4-1 from extending too long into the second pipe body 1-2 and causing skew;

[0060] The moving block 4-6 is arranged in the middle of the two adjusting blocks 4-4, and the cross-section of the moving block 4-6 is an isosceles trapezoidal structure. Guide blocks 4-7 are symmetrically fixed on the upper and lower side walls of the adjusting block 4-4, and the guide blocks 4-7 are slidably embedded in the inside of the adjusting groove 4-5; the end of the threaded rod 2-4 located on the right is rotatably connected to the right side wall of the moving block 4-6 through a bearing.

[0061] Through the above technical solution design, when the No. 1 tube body 1-1 and the No. 2 tube body 1-2 are docked, the threaded rod 2-4 on the left drives the locking column 4-1 to pass through the end of the No. 2 tube body 1-2, and then extends between the two limit plates 4-2, and then rotates the threaded rod 2-4 on the right, and the threaded rod 2-4 on the right drives the moving block 4-6 to move in the middle of the two adjustment blocks 4-4, and drives the two adjustment blocks 4-4 to move relative to each other through the guide block 4-7 and the adjustment slot 4-5, and the distance between the limit plates 4-2 is reduced, and the locking column 4-1 is clamped in the middle of the limit plates 4-2, thereby fixing the No. 1 tube body 1-1 and the No. 2 tube body 1-2. Example 4:

[0062] See Figure 1-7 As shown, based on Example 3, the auxiliary demoulding mechanism 7 includes:

[0063] The sealing plates 7-1 are multiple and are movably mounted in expansion slots 7-2 extending through the side walls of the first tube body 1-1 and the fixed block 2-6 on the left side. A return spring 7-3 is fixedly mounted on the bottom surface of each sealing plate 7-1, and the other end of the return spring 7-3 is fixedly mounted on the side wall of the expansion slot 7-2. An air duct 7-4 is formed on the side wall of the fixed block 2-6, and the interior of the first tube body 1-1 is connected to the interior of the expansion slot 7-2 through the air duct 7-4.

[0064] The movable ring 7-5 is movably arranged inside the No. 1 tube body 1-1, and the surrounding walls of the movable ring 7-5 are in contact with the inner wall of the No. 1 tube body 1-1. The movable ring 7-5 is movably sleeved on the outer side of the left threaded rod 2-4; a plurality of steel wire ropes 7-6 are fixedly connected to the movable ring 7-5, and the other ends of the plurality of steel wire ropes 7-6 are movably passed through the side wall of the fixed block 2-6 and the telescopic slot 7-2, and are fixedly connected to the bottom of the sealing plate 7-1;

[0065] The gas nozzle 7-7 is fixedly connected to the end surface of the first tube body 1-1, and the gas nozzle 7-7 is connected to the external gas source;

[0066] The adjusting screw 7-8 is screwed through the side wall of the end face of the first tube body 1-1 and is rotatably connected to the bottom of the movable ring 7-5 through a bearing; the outer end of the adjusting screw 7-8 is fixedly connected to a plum blossom hand screw 8; the setting of the plum blossom hand screw 8 makes it more convenient to adjust the adjusting screw 7-8;

[0068] Through the above technical solution design, when the carbon fiber tube is demolded and unloaded, the adjusting screw 7-8 is rotated, and the adjusting screw 7-8 drives the movable plate to move to the left, and the sealing plate 7-1 moves toward the inside of the telescopic groove 7-2. The reset spring 7-3 is compressed until the air duct 7-4 is exposed on the outside of the sealing plate 7-1, and the air nozzle 7-7 is connected to the external air source. The high-pressure airflow enters the interior of the No. 1 tube body 1-1 from the air nozzle 7-7, and enters between the carbon fiber tube and the outer wall of the No. 1 tube body 1-1 from the air duct, thereby assisting the separation of the carbon fiber tube from the outer wall of the No. 1 tube body 1-1.

Then, the right threaded rod 2-4 is rotated, and the right threaded rod 2-4 drives the moving block 4-6 to move in the middle of the two adjustment blocks 4-4, and drives the two adjustment blocks 4-4 to move relative to each other through the guide block 4-7 and the adjustment slot 4-5. The distance between the limit plates 4-2 is reduced, and the locking column 4-1 is clamped in the middle of the limit plates 4-2, thereby fixing the No. 1 tube body 1-1 and the No. 2 tube body 1-2;

[0070] Then the carbon fiber prepreg is laid and wound on the outer wall of the core mold body 1. After a series of processing such as hot pressing, the carbon fiber tube is demoulded. At this time, the threaded rod 2-4 on the right is rotated to separate the limit plate 4-2 from the locking column 4-1, and then the adjusting screw 7-8 is rotated. The adjusting screw 7-8 drives the movable plate to move to the left, and the sealing plate 7-1 moves toward the inside of the telescopic slot 7-2. The reset spring 7-3 is compressed until the air duct 7-4 is exposed on the outside of the sealing plate 7-1, and the air nozzle 7-7 is connected to the external air source. The high-pressure airflow enters the interior of the No. 1 tube body 1-1 from the air nozzle 7-7, and enters between the carbon fiber tube and the outer wall of the No. 1 tube body 1-1 from the air duct, assisting the carbon fiber tube to separate from the outer wall of the No. 1 tube body 1-1; at this time, the No. 1 tube body 1-1 and the No. 2 tube body 1-2 are taken out from the inside of the carbon fiber tube from both sides through the external demoulding machine, and the demoulding is completed.

[0071] After adopting the above structure, the beneficial effects of this specific embodiment are:

[0072] 1. The core mold body 1 is formed by the first tube body 1-1 and the second tube body 1-2 being sleeved together. When demolding, the first tube body 1-1 and the second tube body 1-2 are disassembled through the adjustment mechanism 2 and the locking mechanism 4, and then the first tube body 1-1 and the second tube body 1-2 are pulled out from the interior of the carbon fiber tube from two opposite directions, which reduces the length of the core mold to be pulled out and makes demolding more convenient;

[0073] 2. By setting the auxiliary demoulding mechanism 7, high-pressure airflow is injected between the inner wall of the carbon fiber tube and the outer wall of the first tube body 1-1, so that the carbon fiber tube is separated from the outer wall of the first tube body 1-1, making demoulding more convenient.
