Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Please refer to Figures 1 to 4 , Figure 1 A schematic diagram of a specific embodiment of the molding device provided by this utility model; Figure 2 for Figure 1 A partial structural schematic diagram of the molding device shown; Figure 3 for Figure 1 A schematic diagram of the insert structure in the forming device shown; Figure 4 for Figure 1 A schematic diagram of the support rod assembly in the forming device shown.

[0037] In this embodiment, the molding apparatus includes:

[0038] Mold body 1, the inner cavity sidewall of mold body 1 is provided with mold fastening part;

[0039] Insert component 2, insert component 2 can be removed along the mold opening direction of mold body 1; insert component 2 is provided with a plurality of insert fastening parts 21, insert fastening parts 21 are detachably connected to mold fastening parts by fasteners, and a sealing groove 22 is provided on the side of insert component 2 facing the mold fastening part, the sealing groove 22 is arranged around the insert fastening part 21.

[0040] A sealing component is installed in an annular sealing groove 22 to seal the gap between the mold body 1 and the insert component 2.

[0041] Specifically, the mold fastening part is located on the mold body 1 at a position corresponding to the undercut area of ​​the part to be formed. The part to be formed can be a single-sided skin of the machine body or other workpieces with undercut issues. The function of the mold fastening part is to fix the insert component 2. In order to avoid affecting the internal structure of the mold body 1, the fastener is selected to penetrate the mold body 1 and connect and fix it to the insert component 2. Since the fastener penetrates the mold body 1, it is necessary to seal the position of the mold fastening part. In order to reduce damage to the mold body 1, this application provides a sealing groove 22 on the insert component 2. The sealing groove 22 surrounds the outside of the insert fastening part 21. The position of the insert fastening part 21 corresponds to that of the mold fastening part, so that the sealing groove 22 also surrounds the outside of the mold fastening part, thereby preventing airflow between the mold fastening part and the internal cavity of the mold body 1 and ensuring the airtightness of the entire device.

[0042] The molding device provided by this utility model features a separate arrangement of the insert component 2 and the mold body 1, with the insert component 2 being removable from the mold opening direction of the mold body 1. The insert component 2 is located in the inverted mold area of ​​the part to be molded. After the part to be molded is processed, the insert component 2 is removed first, and then the part to be molded is removed, ensuring the integral molding of the part to be molded and guaranteeing its integrity. This eliminates the need for opening molds of multiple components, saving mold costs. At the same time, to avoid sealing problems caused by the setting of the mold fastening part, a sealing groove 22 is provided on the insert component 2. The sealing groove 22 surrounds the insert fastening part 21, and a sealing component is provided inside the sealing groove 22. In other words, the setting of the sealing groove 22 and the sealing component can isolate the inner cavity of the mold body 1 from the mold fastening part, ensuring the overall airtightness of the mold body 1 and the insert component 2.

[0043] In some embodiments, the fastener is a bolt, the mold fastening part is a through hole, and the insert fastening part 21 is a threaded hole. The fastener passes through the mold fastening part and is connected to the insert fastening part 21. Part of the fastener's structure enters the threaded hole, that is, the threaded hole is a blind hole, to avoid penetrating the insert part 2 and affecting the workpiece forming.

[0044] In some embodiments, the top width of the insert component 2 is greater than the bottom width, and the bottom corners of the insert component 2 are provided with rounded chamfers, so that the insert component 2 can be removed after the workpiece forming process is completed. Of course, the structure of the insert component 2 should be designed according to the processing needs, and any structure that can satisfy the requirement of removing the insert component 2 from the mold body 1 is acceptable.

[0045] In some embodiments, the top of the insert component 2 is provided with a lifting ring 23 to connect a lifting device to remove the insert component 2 from the mold body 1.

[0046] In some implementations, it also includes:

[0047] The mold frame 3 is provided with a receiving space for supporting the mold body 1;

[0048] The support rod assembly 4 is mounted on the mold frame 3 at one end and abuts against the outer surface of the mold body 1 at the other end. Specifically, by setting up the support rod assembly 4, a certain pressure can be applied to the outer surface of the mold body 1, thereby ensuring that the mold surface meets the requirements, reducing the deformation of the mold body 1, and improving the processing accuracy of the part to be formed.

[0049] In some embodiments, the support rod assembly 4 includes a support rod body 41, a connector 42, an abutment 43, and a rotating component 44. The connector 42 is disposed on the mold frame 3, the support rod body 41 is mounted on the connector 42, and the rotating component 44 is mounted on the end of the support rod body 41 near the mold body 1. The abutment 43 is hinged to the rotating component 44 and can abut against the surface of the mold body 1. Specifically, the rotating component 44 is configured to meet the angle change requirements of the abutment 43 and adapt to the angle of the outer surface of the mold body 1. The connector 42 can be fixed to the mold frame 3 by bolts or by welding. After the connector 42 is installed, the support rod body 41 is mounted on the connector 42 and adjusted to a suitable position. Then, the support rod body 41 is fixed to the connector 42, ensuring that the abutment 43 is pressed against the outer surface of the mold body 1.

[0050] In some embodiments, the support rod assembly 4 further includes a first fastener 45, which is sleeved on the support rod body 41. When the support rod body 41 moves relative to the connector 42 towards or away from the mold body 1 to the target position, the first fastener 45 locks the connector 42 and the support rod body 41. Specifically, the support rod body 41 is a screw, the connector 42 has a through hole through which the screw passes, and the first fastener 45 is a fastening nut. There can be two first fasteners 45, located on both sides of the second bending surface, for locking the support rod body 41 to ensure the stability of the support body's position, thereby ensuring the stability of the rotating component 44 and the abutment component 43.

[0051] In some embodiments, the connector 42 is an L-shaped gasket. The first bending surface of the connector 42 is disposed on the mold frame 3. The support rod body 41 passes through the second bending surface of the connector 42, and the position of the support rod body 41 relative to the second bending surface is adjustable. Specifically, the through hole is located on the second bending surface. The structure of the L-shaped gasket facilitates the installation of the support rod body 41.

[0052] In some embodiments, the abutment 43 is a flat gasket, the first surface of which can fit against the outer surface of the mold body 1, and the middle of the second surface of the abutment 43 is connected to the rotating component 44. Specifically, choosing a flat gasket as the abutment 43 results in better contact between the flat gasket and the mold body 1, more uniform force distribution, and reduced damage to the mold body 1 due to stress concentration. Connecting the rotating component 44 to the middle of the second surface of the abutment 43 ensures that the pressure applied by the rotating component 44 to the flat gasket is located in the middle of the flat gasket, further guaranteeing the stress stability of the flat gasket.

[0053] In some embodiments, the rotating component 44 is provided with an adjusting bolt 441, the rotating component 44 is fixedly connected to the adjusting bolt 441, the adjusting bolt 441 is engaged with the support rod body 41, and the rotating component 44 can drive the adjusting bolt 441 to rotate relative to the support rod body 41 to change the position of the rotating component 44 and the abutment 43. Specifically, in one embodiment, the first fastener 45 is used to lock the support rod body 41 and the connector 42, achieving initial positioning of the support rod body 41. Then, by turning the adjusting bolt 441, the rotating component 44 is pushed to move towards the mold body 1, thereby pressing the abutment 43 onto the mold body 1. In another embodiment, the position of the rotating component 44 relative to the support rod body 41 is fixed. By adjusting the first fastener 45, for example, by turning the first fastener 45 on the side away from the mold body 1, the relative position between the support rod body 41 and the connector 42 is changed. After the abutment 43 is pressed onto the mold body 1, the first fastener 45 on the side closer to the mold body 1 is tightened to lock the support rod body 41 and the connector 42. The rotating component 44 and the support rod body 41 are detachably connected, making it convenient to replace the abutment 43. Of course, the rotating component 44 and the support rod body 41 can also be fixedly connected.

[0054] Specifically, when processing the workpiece, the position corresponding to the inverted drawing area of ​​the workpiece in the mold is first separated to make the separation insert component 2. At the same time, the insert connecting part and the sealing groove 22 are made to facilitate the connection with the mold body 1 later and ensure airtightness. At the same time, a support rod assembly 4 is provided. The abutting part 43 in the support rod assembly 4 is connected to the mold body 1, and the connecting part 42 in the support rod assembly 4 is connected to the mold frame 3. The profile of the mold body 1 can be adjusted by adjusting the rotating part 44 in the support rod assembly 4 to ensure that the profile of the mold body 1 meets the requirements.

[0055] Before the finished product is formed, a sealing component of the corresponding size, such as a sealing strip, is installed in the sealing groove 22 on the insert component 2. At the same time, the insert component 2 is connected to the mold body 1 using fasteners such as bolts. After the insert component 2 is installed, a pressure holding operation is performed to check the overall airtightness of the mold. If excessive pressure leakage occurs, the insert component 2 needs to be reinstalled until the pressure holding is qualified. After the pressure holding is completed, the mold body 1 and the insert component 2 need to be cleaned to remove impurities from their surfaces. After the mold body 1 and the insert component 2 are cleaned, the product is laid out according to the drawings. After the product is laid out, it is placed in a hot autoclave for heating and pressurization curing. After the product is cured, the fasteners are removed, and a lifting device, such as an overhead crane, is installed in the lifting ring 23 hole of the insert component 2. The lifting ring 23 is then removed using the overhead crane. After the insert component 2 is removed, it is connected to the workpiece through the demolding mechanism with the reserved connection hole. After the connection is completed, the workpiece can be removed.

[0056] The molding device, by adding a detachable insert component 2 to the main body of the mold 1, solves the problem of partial back die forming of the fuselage skin, achieves the purpose of ensuring the overall continuity of the fuselage skin, and saves mold costs.

[0057] In addition to the molding device described above, this utility model also provides a fuselage skin molding system that includes the molding device described above.
