Description

Technical Field

[0001] This application relates to the field of gluing tooling technology, and more specifically, to a flip-type gluing tooling for carbon fiber products. Background Technology

[0002] In the manufacturing process of automotive parts, the mold-closing process (such as the mold-closing stage in molding processes like injection molding, stamping, and die casting) is a crucial step in ensuring the dimensional accuracy, shape consistency, and production stability of parts. Traditional tooling positioning methods are susceptible to machining errors, assembly deviations, or wear, easily leading to relative misalignment between the upper and lower molds. This misalignment can cause dimensional deviations (such as hole misalignment and contour deformation) and surface quality defects (such as flash and wrinkles) in the molded automotive parts, thus increasing the scrap rate and production costs. Furthermore, insufficient locking force during mold closing can cause relative sliding or misalignment of the mold during molding processes (such as high-pressure injection molding and stamping under stress). This not only affects part quality but can also damage the mold (such as cutting edge chipping and cavity wear) and even cause safety accidents (such as mold bursting and parts flying out). Therefore, this solution proposes a flip-type carbon fiber product bonding tooling to address the above problems. Utility Model Content

[0003] This application provides a flip-type carbon fiber product bonding fixture, which can solve the problems of relative misalignment between the upper and lower molds during mold closing and insufficient locking force in the existing flip-type carbon fiber product bonding fixture, resulting in high scrap rate and safety hazards.

[0004] To address the aforementioned technical problems, this application provides a flip-type carbon fiber product bonding fixture, which employs the following technical solution: A flip-type bonding fixture for carbon fiber products includes a support frame, a lower mold, a drive mechanism, an upper mold, a flip frame, a positioning protrusion, a positioning recess, a locking base, a U-bolt, and a locking protrusion. The lower mold and the drive mechanism are both mounted on the support frame. The output end of the drive mechanism is connected to the flipping frame. The upper mold is fixed on the flipping frame, so that the output end of the drive mechanism drives the flipping frame to flip, thereby making the upper mold and the lower mold fit together or separate. The positioning protrusion is located on the support frame, and the positioning recess is located on the flipping frame. The positioning protrusion and the positioning recess can be engaged or separated. The positioning protrusion includes a column positioning component and a conical guide component. The cone angle of the conical guide component is 30°-60°. During mold closing, the conical guide component is used to guide the mold in the initial stage of mold closing, and the column positioning component is used to precisely fit with the inner wall of the positioning recess in the final stage of mold closing to achieve accurate alignment between the upper mold and the lower mold. The locking base is located on the support frame, the locking protrusion is located on the flipping frame, one end of the U-bolt is fastened to the locking protrusion, and the other end of the U-bolt is threaded to the locking base.

[0005] In some embodiments, the locking base is provided with a fixed plate and a handle, the top of the handle being hinged to the fixed plate so that the handle can rotate around the fixed plate; The other end of the U-bolt is threaded to the fixing plate.

[0006] In some embodiments, a nut is also included, and a locking post is provided on the handle, with the other end of the U-bolt passing through the locking post and threadedly connected to the nut.

[0007] In some embodiments, the locking protrusion has a groove, and one end of the U-bolt is fastened into the groove.

[0008] In some embodiments, the support frame is provided with a raised base, and the positioning protrusion is provided on the raised base.

[0009] In some embodiments, the flipping frame is provided with a recessed base, and the positioning recess is provided on the recessed base.

[0010] In some embodiments, when the positioning protrusion and the positioning recess are engaged, the distance between the outer wall of the column positioning member and the inner wall of the recess is less than 0.05 mm.

[0011] Compared with the prior art, the embodiments of this application have the following main advantages: This is a flip-type bonding fixture for carbon fiber products, comprising a support frame, a lower mold, a drive mechanism, an upper mold, a flip frame, a positioning protrusion, a positioning recess, a locking base, U-bolts, and a locking protrusion. The lower mold and drive mechanism are both mounted on the support frame. The output end of the drive mechanism is connected to the flip frame. The upper mold is fixedly mounted on the flip frame, allowing the drive mechanism output end to rotate the flip frame, thus enabling the upper mold and lower mold to fit or separate. The positioning protrusion is located on the support frame, and the positioning recess is located on the flip frame. The positioning protrusion and positioning recess are mutually engaged or disengaged. The positioning protrusion includes a column. The mold consists of a body positioning component and a conical guide component. The conical guide component has a cone angle of 30°-60°. During mold closing, the conical guide component guides the mold in the initial stage of mold closing, while the body positioning component precisely engages with the inner wall of the positioning recess in the final stage of mold closing to achieve accurate alignment between the upper and lower molds. The locking base is mounted on the support frame, and the locking protrusion is mounted on the flipping frame. One end of the U-bolt is fastened to the locking protrusion, and the other end of the U-bolt is threaded to the locking base. When using this flipping carbon fiber product bonding fixture, starting the drive mechanism (such as a motor) causes its output shaft to rotate. The rotational motion is transmitted to the tilting frame via a transmission connection. The tilting frame drives the upper mold (including the carbon fiber component to be bonded) to rotate counterclockwise. As the upper mold approaches the lower mold under the tilting action, the positioning protrusions mounted on the support frame begin to function. First, the conical guide at its front end contacts the entrance of the positioning recess on the tilting frame. Utilizing the principle of "automatic centering" of the conical surface, even if there is an initial deviation of a few millimeters between the upper and lower molds, the conical surface can guide it to the center position. As the upper mold continues to fall, the cylindrical positioning component of the positioning protrusion finally enters the positioning position precisely. Inside the concave hole, after the upper and lower molds are perfectly aligned through the positioning protrusion and the positioning concave hole, one end of the U-bolt is fastened to the locking protrusion of the flipping frame, and the other end passes through the locking base on the support frame and is tightened with a nut. The U-bolt will generate a huge downward clamping force, which will firmly lock the precisely aligned upper and lower molds together, reducing the scrap rate and eliminating safety hazards. This can solve the problems of relative misalignment and insufficient locking force between the upper and lower molds during mold closing in the existing flipping carbon fiber product bonding tooling, resulting in a high scrap rate and safety hazards.

For example, they can refer to a fixed connection, a connection through an intermediary, or a connection within two elements or an interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0018] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0019] This application provides a flip-type bonding fixture for carbon fiber products, such as... Figures 1 to 4 As shown, it includes a support frame 1, a lower mold 2, a drive mechanism 3, an upper mold 4, a flipping frame 5, a positioning protrusion 6, a positioning recess 7, a locking base 8, a U-bolt 9, a locking protrusion 101, and a nut 102; The lower mold 2 and the drive mechanism 3 (motor) are both mounted on the support frame 1. The output end of the drive mechanism 3 is connected to the flipping frame 5. The upper mold 4 is fixedly mounted on the flipping frame 5, so that the output end of the drive mechanism 3 drives the flipping frame 5 to flip, thereby making the upper mold 4 fit or separate from the lower mold 2. Before the tooling begins operation, the drive mechanism 3 is in a power-off or standby state. At this time, the tilting frame 5, supported by the output end of the drive mechanism 3, remains in the open position, and the upper mold 4, fixed on the tilting frame 5, is raised accordingly, maintaining sufficient space distance with the lower mold 2, fixed on the support frame 1. This state facilitates the operator in accurately placing the carbon fiber preform to be glued onto the surface of the lower mold 2, providing a spacious and safe working space. After the workpiece placement process is completed, the operator starts the drive mechanism 3. The output end of the drive mechanism 3 (such as the output shaft of a motor) begins to rotate in a preset direction and speed. The output end of the drive mechanism 3 transmits the rotational power to the tilting frame 5 through a transmission connection (e.g., directly connected through a coupling, or through a reducer, gear set, etc.), causing the tilting frame 5 to tilt accordingly. Since the upper mold 4 is firmly fixed to the tilting frame 5 by bolts or clamps, the upper mold 4 tilts along with the tilting frame 5, moving closer to the lower mold 2.

[0020] In this embodiment, the drive mechanism 3 is a motor. In other embodiments, the drive mechanism 3 can be a cylinder or a hydraulic cylinder, as long as the output end of the drive mechanism 3 drives the flipping frame 5 to flip, thereby making the upper mold 4 fit or separate from the lower mold 2.

[0021] The positioning protrusion 6 is provided on the support frame 1 (the support frame 1 is provided with a protrusion base 11, and the positioning protrusion 6 is provided on the protrusion base 11), and the positioning recess 7 is provided on the flip frame 5 (the flip frame 5 is provided with a recess base 51, and the positioning recess 7 is provided on the recess base 51). The positioning protrusion 6 and the positioning recess 7 are either interlocked or separated. The positioning protrusion 6 includes a column positioning component 61 and a cone guide component 62. The cone angle of the cone guide component 62 is 45°. During mold closing, the cone guide component 62 is used to guide the mold in the initial stage of mold closing, and the column positioning component 61 is used to precisely fit with the inner wall of the positioning recess 7 in the final stage of mold closing (when the positioning protrusion 6 and the positioning recess 7 are interlocked, the distance between the outer wall of the column positioning component 61 and the inner wall of the positioning recess 7 is less than 0.05mm), so as to achieve precise alignment between the upper mold 4 and the lower mold 2.

[0022] When the drive mechanism 3 drives the tilting frame 5 to move the upper mold 4 closer to the lower mold 2, until the two are a certain distance apart (e.g., 20-40 mm), the mold closing process enters its initial stage. At this time, the positioning protrusion 6 on the support frame 1 begins to approach the positioning recess 7 on the tilting frame 5. The conical guide 62 at the front end of the positioning protrusion 6 enters the entrance area of ​​the positioning recess 7 first. At this time, there may be a slight initial deviation between the axis of the positioning protrusion 6 and the axis of the positioning recess 7. The conical guide 62 contacts the edge of the opening of the positioning recess 7 with its 45° conical slope. Utilizing the self-adaptability of the conical surface, even with the initial deviation, under continuous mold closing pressure, the slope will generate a radial component force, automatically "guiding" and "correcting" the positioning recess 7 (along with the entire tilting frame 5 and the upper mold 4) to the correct position coaxial with the positioning protrusion 6. This process achieves coarse positioning, effectively compensating for the transmission error and cumulative installation error of the drive mechanism 3 itself, and avoiding damage to the mold due to hard impact.

[0023] In this embodiment, the cone angle of the cone guide 62 is 45°. In other embodiments, the cone angle of the cone guide 62 can be changed according to the actual situation. For example, the cone angle of the cone guide 62 can be 30°, or 35°, or 40°, or 50°, or 55°, or 60°. As long as the cone angle of the cone guide 62 is between 30° and 60°, the cone guide 62 can be used for guidance in the initial stage of mold closing.

[0024] The locking base 8 is mounted on the support frame 1, and the locking protrusion 101 is mounted on the flip frame 5. One end of the U-bolt 9 is fastened to the locking protrusion 101, and the other end of the U-bolt 9 is threadedly connected to the locking base 8. The locking base 8 is provided with a fixing plate 81 and a handle 82. The top end of the handle 82 is hinged to the fixing plate 81, so that the handle 82 can rotate around the fixing plate 81. The other end of the U-bolt 9 is threadedly connected to the fixing plate 81. The handle 82 is provided with a locking post 821, and the other end of the U-bolt 9 passes through the locking post 821 and is threadedly connected to the nut 102.

[0025] After the drive mechanism 3 completes its rotation and the positioning protrusion 6 and positioning recess 7 are fully engaged, achieving precise alignment of the upper mold 4 and lower mold 2, the fixture enters the locking state. At this time, the open end of the U-bolt 9 (i.e., the bottom of the U-shape) is fastened to the locking protrusion 101 of the rotating frame 5 from above or the side. The locking protrusion 101 has a groove 1011, and one end of the U-bolt 9 is fastened in the groove 1011 to ensure that the U-bolt 9 will not slip under force. Then, the other end of the U-bolt 9 is passed through the locking post 821. The operator screws the nut 102 onto the other end of the U-bolt 9 that has passed through the locking post 821. As the nut 102 is tightened, the U-bolt 9 is pulled, thereby generating a huge downward clamping force, pressing the upper mold 4 and lower mold 2 tightly together. Pressing down the handle 82, only a small amount of hand force is needed to generate a strong linear pulling force on the U-bolt 9, achieving the effect of "rapid clamping".

[0026] This flip-type carbon fiber product bonding fixture includes a support frame 1, a lower mold 2, a drive mechanism 3, an upper mold 4, a flipping frame 5, a positioning protrusion 6, a positioning recess 7, a locking base 8, a U-bolt 9, and a locking protrusion 101. The lower mold 2 and the drive mechanism 3 are both mounted on the support frame 1. The output end of the drive mechanism 3 is connected to the flipping frame 5. The upper mold 4 is fixedly mounted on the flipping frame 5, so that the output end of the drive mechanism 3 drives the flipping frame 5 to flip, thereby causing the upper mold 4 to fit or separate from the lower mold 2. The positioning protrusion 6 is located on the support frame 1, and the positioning recess 7 is located on the flipping frame 5. The positioning protrusion 6 and the positioning recess 7 are mutually engaged or disengaged, positioning... The protrusion 6 includes a column positioning component 61 and a conical guide component 62. The cone angle of the conical guide component 62 is 30°-60°. During mold closing, the conical guide component 62 is used for guidance in the initial stage of mold closing, and the column positioning component 61 is used for precise engagement with the inner wall of the positioning recess 7 in the final stage of mold closing to achieve accurate alignment between the upper mold 4 and the lower mold 2. The locking base 8 is mounted on the support frame 1, and the locking protrusion 101 is mounted on the flipping frame 5. One end of the U-bolt 9 is fastened to the locking protrusion 101, and the other end of the U-bolt 9 is threadedly connected to the locking base 8. When using this flipping carbon fiber product bonding fixture, the drive mechanism 3 (such as a motor) is started, and its output... The output shaft begins to rotate, and this rotational motion is transmitted to the flipping frame 5 through the transmission connection. The flipping frame 5 drives the upper mold 4 (including the carbon fiber parts to be glued) to rotate counterclockwise. When the upper mold 4 approaches the lower mold 2 under the action of flipping, the positioning protrusion 6 installed on the support frame 1 begins to function. First, the conical guide 62 at its front end contacts the entrance of the positioning recess 7 on the flipping frame 5. Utilizing the principle of "automatic centering" of the conical surface, even if there is an initial deviation of a few millimeters between the upper mold 4 and the lower mold 2, the conical surface can guide it to the center position. As the upper mold 4 continues to fall, the cylindrical positioning part 61 of the positioning protrusion 6 finally enters precisely. Inside the positioning recess 7, after the upper mold 4 and lower mold 2 are perfectly aligned through the positioning protrusion 6 and positioning recess 7, one end of the U-bolt 9 is fastened to the locking protrusion 101 of the flipping frame 5, and the other end passes through the locking base 8 on the support frame 1 and is tightened with the nut 102. The U-bolt 9 will generate a huge downward clamping force, which will firmly lock the precisely aligned upper mold 4 and lower mold 2 together, reducing the scrap rate and eliminating safety hazards. This can solve the problems of the relative position misalignment and insufficient locking force of the upper mold 4 and lower mold 2 during mold closing in the existing flipping carbon fiber product bonding tooling, resulting in a high scrap rate and safety hazards.
