Description

Technical Field

[0001] This utility model belongs to the field of foam material molding mold technology, and in particular relates to an integrated molding mold for an aircraft adapter. Background Technology

[0002] An aircraft adapter is an auxiliary device inside an aircraft that serves as a connection, playing a crucial role in the aircraft's storage, transportation, and launch. An aircraft adapter typically consists of a metal shell, a rubber-plastic sheet, a rigid polyurethane foam layer, and an anti-static cloth. The adapter is generally manufactured as follows: first, the rigid polyurethane foam is cured and molded; then, the rubber-plastic sheet is adhered to the surface of the rigid polyurethane foam; finally, the anti-static cloth is attached.

[0003] The aforementioned molding methods are not only cumbersome, but the bonding of the rigid polyurethane foam layer to the rubber-plastic board is mostly done manually. The thickness of the adhesive layer affects the overall thickness of the adapter, making it impossible to guarantee the consistency of the final product's quality. Furthermore, existing molding dies have complex structures, high processing costs, and are prone to molding defects such as dents, bubbles, softening, and whitening on the product surface during the molding process. In addition, rigid polyurethane foam expands rapidly, and some foaming dies, due to the large number of parts, cannot be assembled in time during foaming, resulting in partial overflow of polyurethane foam, severely impacting product quality.

[0004] For example, patent document CN111645248A discloses a mold for integrally molding an irregularly shaped adapter, including a base plate, a mold frame vertically fixed to the base plate, and an upper mold rotatably fixed in the middle of the mold frame. The upper mold, mold frame, and base plate form a hollow cavity. The top surface of the upper mold is parallel to the plane of the adapter guide groove to be molded, and the top surface of the upper mold is not parallel to the upper surface of the base plate. This effectively prevents the PTFE film from falling off, ensures the integrity of the adapter, meets the requirements for wear resistance, high temperature resistance, and anti-adhesion performance, and conforms to the integrated design of structure and function. However, it cannot avoid molding defects such as dents, bubbles, softening, and whitening during molding. Moreover, this mold is only suitable for molding this irregularly shaped adapter and is not suitable for molding other non-irregularly shaped adapters.

[0005] Therefore, it is necessary to design a one-piece molding mold specifically for aircraft adapters that has a simple process, fewer manual operations, high product quality consistency, and can adapt to the fast foaming speed of rigid polyurethane foam, in order to improve the quality and production efficiency of aircraft adapters and avoid molding defects such as dents, bubbles, softening and whitening during the molding process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0030] like Figures 1-3 As shown in the figure, this utility model embodiment provides an integrated molding mold for an aircraft adapter, including an upper mold 1 and a lower mold 2. Both the upper mold 1 and the lower mold 2 are provided with molding grooves, which are symmetrically distributed in a grid pattern. The upper mold 1 includes an upper part 15 and an upper part 16, and the lower mold 2 includes an upper part 27 and a lower part 28. The molding groove of the upper mold 1 is located in the lower part 16, and the molding groove of the lower mold 2 is located in the upper part 27. The molding groove structures of the upper mold 1 and the lower mold 2 correspond to each other. The upper part 15 of the upper mold is a flat surface, and the lower part 28 of the lower mold is a flat surface. The lower part 16 of the upper mold and the upper part 27 of the lower mold are connected to form a closed cavity, which can simultaneously mold four identical adapters. By setting the upper mold 1 and the lower mold 2, the adapter can be integrally molded in the closed cavity formed by the upper mold 1 and the lower mold 2, avoiding the problem of inconsistent overall thickness of the final adapter caused by later gluing, thus improving the consistency of product quality.

[0031] In this embodiment, the bottom of the forming groove of the upper mold 1 is set as a concave semi-circular shape and is provided with a plurality of vent holes 11. The vent holes 11 are evenly distributed around the periphery and center of the forming groove of the upper mold 1. The edges of the forming groove of the upper mold 1 in the width direction are set as the same concave semi-circular shape. By setting the vent holes 11, the problems of forming defects such as dents, bubbles, softness and whitening on the surface of the adapter after forming can be effectively reduced.

[0032] In this embodiment, two pull ring holes 12 are provided on both sides of the upper mold 1 in the width direction. The pull ring holes 12 are symmetrically distributed along the two axes of the upper mold 1 and are used to install pull rings. When using pull rings, the one-piece mold is subjected to uniform force.

[0033] In this embodiment, the upper mold 1 has a boss 13 at the middle of the outer long edge of the four forming grooves. The outer side of the boss 13 is aligned with the long edge of the upper mold 1 for positioning and to cooperate with the structural features of the lower mold.

[0034] In this embodiment, the lower part 16 of the upper mold is provided with a plurality of threaded holes A14 on its four sides, and the upper part 27 of the lower mold is provided with the same threaded holes B25 at corresponding positions. The upper mold 1 and the lower mold 2 are connected by screws provided in the threaded holes A14 and the threaded holes B25. The lower part 16 of the upper mold is provided with an average of 3 threaded holes A14 on each side to ensure the tightness of the upper mold 1 and the lower mold 2 when they are closed.

[0035] In this embodiment, the bottom of the forming groove of the lower mold 2 is set as an outwardly convex semi-circular shape, and the edge of the forming groove of the lower mold 2 in the width direction is set as the same outwardly convex semi-circular shape as the bottom, and matches the inwardly concave semi-circular shape of the edge of the upper mold 1, so as to match the structural features corresponding to the upper mold.

[0036] In this embodiment, a positioning pin 22 and a disassembly cover plate 23 are installed at the bottom of the forming groove of the lower mold 2. The positioning pin 22 passes through the disassembly cover plate 23 from the lower part 28 of the lower mold and is located at the center of the bottom of the forming groove of the lower mold 2. Two adjacent positioning pins 22 in the width direction of the lower mold 2 are installed on the same disassembly cover plate 23. The disassembly cover plate 23 is installed on the lower part 28 of the lower mold by screws. By setting the positioning pin 22 and the disassembly cover plate 23, an interface for connection with the aircraft is reserved for the adapter during the forming process, which facilitates the use of the adapter. The installation of two adjacent positioning pins 22 in the width direction of the lower mold on the same disassembly cover plate 23 simplifies the structure of the mold, facilitates disassembly and assembly, and reduces the difficulty of processing the mold and the cost of components.

[0037] In this embodiment, the bottom of the two adjacent forming grooves in the width direction of the lower mold 28 is provided with a through groove 24, and the disassembly cover plate 23 is disposed in the through groove 24. A total of two disassembly cover plates 23 are provided in the lower mold 28, which improves the reliability of the installation of the disassembly cover plate 23.

[0038] In this embodiment, the four corners of the upper part 27 of the lower mold are all set with the same triangular notch step 26. The edge of the upper part 27 of the lower mold along the length direction is provided with a groove that cooperates with the boss 13 of the upper mold 1. The triangular notch step 26 facilitates the demolding after the mold is closed, and makes it easy to separate the upper mold 1 and the lower mold 2.

[0039] In this embodiment, handle holes 21 are provided on both sides of the lower mold 2 in the width direction. The handle holes 21 are symmetrically distributed along the two axes of the lower mold 2, which makes the installation of the handle simple and the lower mold 2 is evenly stressed when using the handle.

[0040] In use, first separate the upper mold 1 from the lower mold 2, install and fix the positioning pin 22 and the disassembly cover plate 23 from the lower mold. Then, lay the materials required for the aircraft adapter in sequence at the bottom of the lower mold forming groove. For example, first lay the rubber sheet flat at the bottom of the lower mold forming groove and compact it, with the smooth side of the rubber sheet facing down and the mushroom head column facing up, and the mushroom head pointing towards the upper mold. Then, pour the mixed rigid polyurethane foam material into the lower mold forming groove. Then, connect the upper mold 1 and the lower mold 2 with screws to close the mold. After curing, separate the upper mold 1 from the lower mold 2 from the triangular notch step 26, then remove the disassembly cover plate 23 and the positioning pin 22. Then, use a wooden stick to gently tap the cured adapter in the lower mold 2 through the channel of the positioning pin 22 to remove it and obtain the one-piece molded adapter.

[0041] This invention manufactures the adapter product using a combined upper and lower mold, avoiding the problem of inconsistent overall thickness caused by subsequent glue bonding, thus improving product quality consistency. Venting holes in the upper mold's forming groove effectively reduce molding defects such as dents, bubbles, softening, and whitening on the adapter's surface after molding. Positioning pins in the lower mold improve the placement accuracy of the materials used in the adapter, enhancing the overall product precision. A detachable cover plate and triangular notch step in the lower mold simplify demolding and disassembly of the upper and lower molds. This integrated molding die features high positioning accuracy, fewer components, and a simple structure, effectively improving production efficiency while ensuring product precision.

[0042] The quality and dimensions of the aircraft adapters manufactured using the integrated mold of the aircraft adapter described in this embodiment were tested. Four adapters manufactured by the integrated mold of this embodiment were randomly tested, and the test data are shown in Table 1. The test data in Table 1 shows that the quality and dimensions of the adapter products manufactured using the integrated mold of this embodiment meet the requirements.
