[0031] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.
[0032] Next, we will combine the appendix Figures 1-7 This application describes a molding die (hereinafter referred to as the molding die) for a carbon fiber box liner, which is used to mold a box liner based on carbon fiber composite material.
[0033] Figure 1 A three-dimensional schematic diagram of the molding die used for the inner liner of a carbon fiber box; Figure 2 for Figure 1 A schematic diagram of the structure from one perspective.
[0034] The molding die includes a base plate 120, and a protrusion 110 matching the shape to be molded is provided on one side of the base plate 120. The protrusion 110 is hollow and is engaged with the base plate 120.
[0035] The protrusion 110 is composed of a plurality of side plates and a top plate.
[0036] Next, combine Figures 3-6 To describe the structure of the molding die. Figure 3 This is a schematic diagram of the molding die with the top plate removed, according to an embodiment of this application. Figure 4 This is a schematic diagram of the molding die without the bottom plate in an embodiment of this application; Figure 5 for Figure 4 A schematic diagram of the structure with the asymmetrical side panels hidden in the middle; Figure 6 This is a three-dimensional structural diagram of the base plate according to an embodiment of this application. The inner liner 200 formed by the molding die is shown below. Figure 7 As shown, the molded inner liner 200 is not removed from the mold. Figure 8 As shown.
[0037] The protruding portion 110 has a cuboid structure, which is surrounded by four sides connected in sequence, and each side includes at least one side plate 111.
[0038] The side away from the bottom plate 120 is provided with a top plate 114. Preferably, the top plate 114 is embedded in the cavity surrounded by the side, and the outer side of the top plate 114 is at the same plane as the end of the side plate 111. In this embodiment, each side includes two side plates 111, and the joint of the two side plates 111 is provided with a reinforcing rib 112 to reinforce the strength of the joint.
[0039] Preferably, the reinforcing rib 112 can be a metal piece, and the two sides of the metal piece are respectively provided with a platform part 112a (also called a foot), which abuts against the top plate 114 or the bottom plate 120.
[0040] Preferably, the two side plates 111 of each side are designed asymmetrically (the lengths of the two ends of the side plate are different, and the side plate is designed in a trapezoidal shape, which is beneficial for taking out the side plate after molding). One side plate 111 is provided with a protrusion 113, which is in a cuboid shape, and is used to form a notch 210 on the inner container (see Figure 7 ).
[0041] In this embodiment, one side of the side plate 111 is provided with a step 1111, which is embedded in the groove 121 of the bottom plate 120 to fix the protruding portion 110 on the bottom plate 120. The outer side of the groove 121 is provided with a protrusion 123 surrounding the groove 121 and a recess 122 surrounding the protrusion 123, and the combination of the recess 122 and the protrusion 123 is used to form a frame 220 of the inner container (see Figure 7 ).
[0042] In other embodiments, the side plate can be designed as follows.
[0043] When the inner container is molded, the parts (carbon fiber composite material) are stacked according to the preset order and cover the surface of the protruding portion 110 and partially on the bottom plate 120, and a shape-matched outer mold (wraps the product) is put on,
[0044] Then, molding (hot pressing) is performed, the outer mold is removed as shown in Figure 8 , then the bottom plate 120 is removed, and then the side plates are pulled out from one side, the side plate with a longer length towards the bottom plate 120 is pulled out first, then the other side plate of the same side is pulled out, and the side walls of other sides are pulled out in sequence, and then the top plate is taken out.
[0045] Compared with the single-sided mold used in the current inner container forming, the mode is difficult to demold, greatly improves the demolding efficiency, and does not damage the product during the demolding process.
[0046] The above examples are only for illustrating the technical concept and characteristics of the application, and the purpose is to enable those skilled in the art to understand the content of the application and implement it, and cannot limit the protection scope of the application. Any equivalent transformation or modification according to the spirit and principle of the application should be covered within the protection scope of the application.
