Description

Technical Field

[0001] This utility model relates to the field of aluminum honeycomb panel manufacturing technology, specifically to a hyperbolic honeycomb composite panel mold. Background Technology

[0002] Honeycomb panels, also known as honeycomb sandwich structures, are a widely used composite structure. Compared with ordinary metal panels, metal honeycomb panels have significant advantages in specific strength, thermal insulation, sound insulation, and vibration reduction performance. Honeycomb panels have broad application prospects in aircraft shells, heat insulation panels, and aero engines. However, their components are mostly complex curved components, which places extremely high demands on the manufacturing technology of metal honeycomb panel components.

[0003] Currently, several methods exist for preparing curved honeycomb cores and honeycomb panels. The fabrication of hyperbolic honeycomb panels involves separately machining the face plate, honeycomb core, and base plate into curved surfaces, then combining and connecting them to form the hyperbolic honeycomb panel. However, existing hyperbolic honeycomb panel composite molds require a different mold for each product, resulting in poor mold versatility and high manufacturing and management costs. Utility Model Content

[0004] This utility model provides a hyperbolic honeycomb composite panel mold, which can overcome the shortcomings of existing molds, such as poor versatility, high manufacturing and management costs.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A hyperbolic honeycomb composite panel mold includes a support platform and a first molding mold, a second molding mold, and a third molding mold fixed to the support platform by a fixing component. The two first molding molds are symmetrically arranged along the center line of the support platform, and the two third molding molds are respectively arranged at both ends of the support platform. Zero or several second molding molds are arranged between the first molding mold and the third molding mold. The upper surface of the first molding mold or the first molding mold and the second molding mold forms a mating curved surface adapted to the center part of the hyperbolic honeycomb panel to be composited, and the upper surface of the third molding mold forms a mating plane adapted to the edge part of the hyperbolic honeycomb panel to be composited.

[0007] Furthermore, the fixing component includes a fixing screw, the lower end of which is threadedly connected to the support platform, and a locking nut is connected to the top of the fixing screw. Fixing holes matching the fixing screw are provided on the first molding die, the second molding die, and the third molding die. The first molding die, the second molding die, or the third molding die is fixed by the cooperation of the locking nut and the support platform.

[0008] Furthermore, a receiving opening for accommodating the locking nut is formed at the top of the fixing hole.

[0009] Furthermore, the support platform has multiple positioning holes arranged in an array, and the lower part of the fixing screw is threadedly connected to the positioning holes.

[0010] Furthermore, a limiting ring is formed at the lower part of the fixing screw, and a support step adapted to the limiting ring is formed at the top of the positioning hole. When the fixing screw and the positioning hole are threadedly connected, the upper surface of the limiting ring is flush with the upper surface of the support platform.

[0011] Furthermore, the first molding die, the second molding die, and the third molding die are symmetrically arranged along the centerline of the length direction of the support platform.

[0012] Furthermore, the thickness of the first molding die and the second molding die decreases from one end to the other along their length.

[0013] Furthermore, the support platform includes a support frame and a support platform fixed to the top of the support frame, and the first molding die, the second molding die, and the third molding die are fixed to the support platform.

[0014] Furthermore, the first molding die, the second molding die, and the third molding die are all made of foam material.

[0015] Beneficial effects: This utility model uses a first molding mold, a second molding mold, and a third molding mold made of foam material. The upper surfaces of the first molding mold, the second molding mold, and the third molding mold can be easily processed to conform to the processing parameters of the hyperbolic honeycomb composite panel to be laminated. This provides reliable support for the panel, honeycomb core, and base plate during lamination. At the same time, since the first molding mold, the second molding mold, and the third molding mold are all detachably connected to the support platform, this mold can achieve the composite processing of hyperbolic honeycomb panels with different curvatures and other processing parameters by combining or replacing the first molding mold, the second molding mold, and the third molding mold. This effectively overcomes the defects of poor versatility, high manufacturing cost, and high management cost of existing molds. Attached Figure Description

[0019] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0020] like Figs. 1-3 As shown, this embodiment provides a hyperbolic honeycomb composite panel mold, including a support platform and a first molding mold 2, a second molding mold 3, and a third molding mold 4 fixed to the support platform by a fixing component. The first molding mold 2, the second molding mold 3, and the third molding mold 4 are all made of foam material to facilitate easy processing of the upper surfaces of the first molding mold, the second molding mold, and the third molding mold into surfaces that conform to the processing parameters of the hyperbolic honeycomb composite panel to be composited. The two first molding molds 2 are symmetrically arranged along the centerline of the support platform to form a symmetrical curved surface adapted to the composite hyperbolic honeycomb panel. The two third molding molds 4 are respectively disposed on the support platform. At both ends of the support platform, one or more second molding molds 3 are set between the first molding mold 2 and the third molding mold 4. The upper surface of the first molding mold 2 or the first molding mold 2 and the second molding mold 3 forms a mating curved surface adapted to the center part of the hyperbolic honeycomb panel to be composited. The upper surface of the third molding mold 4 forms a mating plane adapted to the edge part of the hyperbolic honeycomb panel to be composited. Thus, by using different first molding molds 2 and third molding molds 4 or combinations of first molding molds 2, second molding molds 3 and third molding molds 4, it is suitable for composite processing of hyperbolic honeycomb panels with different curvature and other processing parameters, so as to effectively improve the versatility of the mold.

[0021] For example, a composite hyperbolic honeycomb panel is constructed by two symmetrically arranged first molding molds 2, two third molding molds 4 disposed at both ends of the support platform, and a second molding mold 3 disposed between the first molding molds 2 and the third molding molds 4. Fig. 1 The composite processing of hyperbolic honeycomb panels can be completed by sequentially combining the base plate, honeycomb core, and face plate on the support surface shown.

[0022] In this example, the thickness of the first molding die 2 and the second molding die 3 decreases from one end to the other along their length, thereby better adapting to the composite processing of different curvatures on both sides of the hyperbolic honeycomb panel.

[0023] See appendix Fig. 3 The fixing component includes a fixing screw 8, the lower end of which is threaded to the support platform. A locking nut 10 is connected to the top of the fixing screw 8. Fixing holes 5 matching the fixing screw 8 are provided on the first molding die 2, the second molding die 3, and the third molding die 4. The first molding die 2, the second molding die 3, or the third molding die 4 is fixed by the cooperation of the locking nut 10 and the support platform.

[0024] The fixing components with the above structure can not only facilitate the connection between the fixing components and the support platform, so as to make adaptive adjustments to the position of the fixing components according to the processing parameters of the hyperbolic honeycomb panel to be composited, but also facilitate the fixing of the first molding mold 2, the second molding mold 3 or the third molding mold 4 by the cooperation of the locking nut 10 and the support platform, so as to adapt to the composite production and processing of hyperbolic honeycomb panels of different specifications.

[0025] Preferably, a receiving opening 11 for accommodating the locking nut 10 is formed at the top of the fixing hole 5.

[0026] By setting the receiving port 11, when the first molding mold 2, the second molding mold 3, or the third molding mold 4 is fixed on the support platform, the locking nut 10 and the fixing screw 8 can be set together in the receiving port 11 to avoid protruding from the upper surface of the molding mold and causing adverse effects on the composite of the honeycomb panel.

[0027] In this embodiment, a plurality of positioning holes 7 are provided on the support platform in an array, and the lower part of the fixing screw 8 is threadedly connected to the positioning holes 7.

[0028] The positioning holes 7 arranged in an array allow the fixing components to be freely adjusted in position on the support platform, thereby enabling the fixing of the molding molds by using different combinations of the first molding mold 2, the second molding mold 3, or the third molding mold 4 according to the processing parameters of the hyperbolic honeycomb panel to be composited.

[0029] Preferably, a limiting ring 9 is formed at the lower part of the fixing screw 8, and a support step adapted to the limiting ring 9 is formed at the top of the positioning hole 7. When the fixing screw 8 and the positioning hole 7 are threadedly connected, the upper surface of the limiting ring 9 is flush with the upper surface of the support platform (not shown in the figure).

[0030] By setting the limiting ring 9, the lower end position of the fixing bolt 8 can be limited, ensuring that the length of the exposed part of the fixing bolt 8 after it is fixed on the support platform is consistent. This makes it easy to adapt to the fixing of the first forming mold 2, the second forming mold 3 and the third forming mold 4 with different heights, without having to select fixing bolts of different lengths according to the height of the forming mold.

[0031] In this example, the first molding mold 2, the second molding mold 3, and the third molding mold 4 are symmetrically arranged along the centerline of the length direction of the support platform.

[0032] Setting it along the length direction can effectively divide the entire molding mold into multiple first molding molds 2, second molding molds 3 and third molding molds 4, thereby effectively reducing the manufacturing difficulty of the molding mold.

[0033] Preferably, in order to reduce the weight and manufacturing difficulty of the support platform, the support platform includes a support frame 1 and a support platform 6 fixed on the top of the support frame 1. The first molding mold 2, the second molding mold 3 and the third molding mold 4 are fixed on the support platform 6, and the positioning hole 7 is opened on the support platform 6.

[0034] Beneficial effects: In this embodiment, firstly, based on the processing parameters of the hyperbolic honeycomb composite panel to be composited, the foam material is sampled to make a first molding mold 2 and a third molding mold 4, or a combination of a first molding mold 2, a second molding mold 3, and a third molding mold 4. Then, the position of the fixing component is determined according to the first molding mold 2, the second molding mold 3, or the third molding mold 4. After that, the first molding mold 2, the second molding mold 3, or the third molding mold 4 is fixed on the support platform 6 by the fixing component. Finally, the base plate, the honeycomb core, and the panel are composited in sequence to complete the composite processing of the hyperbolic honeycomb panel. As can be seen, the mold of this utility model, through the first molding mold 2, the second molding mold 3, and the third molding mold 4 made of foam material, can easily process the upper surfaces of the first molding mold 2, the second molding mold 3, and the third molding mold 4 to conform to the processing parameters of the hyperbolic honeycomb composite panel to be laminated, thereby providing reliable support for the panel, honeycomb core, and base plate during lamination. At the same time, since the first molding mold, the second molding mold, and the third molding mold are all connected to the support platform in a detachable manner, this mold can achieve the composite processing of hyperbolic honeycomb panels with different curvatures and other processing parameters by combining or replacing the first molding mold, the second molding mold, and the third molding mold, effectively overcoming the defects of poor versatility and high manufacturing and management costs of existing molds.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
