[0002] With the development of mining transport vehicles towards large-scale, high load capacity, and high efficiency, the increase in their own weight has led to an increase in energy consumption and operating costs. Due to its excellent properties such as high strength, high temperature resistance, corrosion resistance, and impact resistance, basalt fiber composite materials have higher specific strength and specific stiffness compared to traditional steel.

[0026] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application.

[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0028] Embodiment 1, as Figures 1 - 4 shown, a compression molding device for a basalt fiber composite material reinforced structure according to an embodiment of the present application includes a bottom bearing structure 1, a top pressing structure 2, a feeding head 3, and a mold 4.

[0029] Among them, the bottom bearing structure 1 is used to support the mold body to be processed.

[0030] Specifically, the bottom bearing structure 1 includes a bottom support 11, a plurality of guide rods 12, and a bearing table 13. The plurality of guide rods 12 are respectively fixed to the four corners of the bottom support 11, and the bearing table 13 is fixedly sleeved on the plurality of guide rods 12. The bearing table 13 is used to bear the lower part of the mold 4, and a lower cooling plate 131 is provided between the bearing table 13 and the lower part of the mold 4.

[0031] As Figure 1 and Figure 2As shown, the bottom bearing structure 1 further includes four groups of buffer components 14. The four groups of buffer components 14 are symmetrically arranged along the height direction between the bottom bearing structure 1 and the top pressing structure 2. Each group of buffer components 14 includes two elastic telescopic members 141, two guiding columns 142 and an abutting block 143. The two elastic telescopic members 141 are fixedly connected to the bottom bearing structure 1 or the top pressing structure 2. The two guiding columns 142 are fixedly connected to the bottom bearing structure 1 or the top pressing structure 2. The abutting block 143 is fixedly connected to the ends of the two elastic telescopic members 141 and the two guiding columns 142.

[0032] It can be understood that the four groups of buffer components 14 are arranged in an up-and-down opposite manner. In this way, rigid collision can be avoided during the mold closing process. It should be noted that the elastic telescopic member 141 can adopt a hydraulic buffer or a spring buffer structure design, as long as it has self-resetting and damping force.

[0033] The bottom bearing structure 1 further includes a horizontal displacement component 15. The horizontal displacement component 15 includes a horizontal telescopic member 151, a connecting block 152, a horizontal displacement table 153 and two guiding blocks 154. The horizontal telescopic member 151 is arranged along the horizontal direction of the bearing table 13. The connecting block 152 is fixedly connected to the telescopic end of the horizontal telescopic member 151. The horizontal displacement table 153 is arranged along the horizontal direction of the bearing table 13 and is fixedly connected to the connecting block 152. The two guiding blocks 154 are fixedly connected to the bearing table 13 along the horizontal direction of the bearing table 13. The horizontal displacement table 153 is slidably matched with the two guiding blocks 154. The lower part of the mold 4 is fixedly connected to the horizontal displacement table 153.

[0034] It can be seen from this that the lower part of the mold 4 can achieve horizontal displacement relative to the bearing table 13 through the horizontal telescopic member 151, which is convenient for mold taking operation and the installation or disassembly of the lower part of the mold 4.

[0035] The top pressing structure 2 is fixedly connected to the top end of the bottom bearing structure 1. The displacement end of the top pressing structure 2 has a lifting function relative to the bottom bearing structure 1.

[0036] Specifically, the top pressing structure 2 includes a pressing telescopic member 21, two guiding rods 22 and a pressing table 23. The pressing telescopic member 21 is fixedly connected to the pressing table 23 through a support rod. The two guiding rods 22 are symmetrically and fixedly connected to the pressing table 23 respectively. The displacement end of the pressing telescopic member 21 is slidably sleeved on the guiding rod 22. The displacement end of the pressing telescopic member 21 penetrates through the pressing table 23 through a support rod and is connected with an upper cooling plate 231. The upper part of the mold 4 is fixedly connected to the upper cooling plate 231.

[0037] It should be noted that in the specific embodiment of the present application, the horizontal telescopic member 151 and the pressing telescopic member 21 can be existing technologies such as hydraulic cylinders with linear telescopic functions.

[0038] The material feeding head 3 is connected to the top pressing structure 2; specifically, at the position where the displacement end of the pressing telescopic member 21 penetrates through the pressing table 23, an injection head 31 is fixedly connected. The injection head 31 is communicated with the material feeding head 3, and the injection head 31 is used to convey the molding material into the mold 4.

[0039] The mold 4 includes two upper and lower parts, wherein the upper part is detachably and fixedly connected to the displacement end of the top pressing structure 2, and the lower part is detachably and fixedly connected to one end of the bottom bearing structure 1 facing the top pressing structure 2.

[0040] In a specific embodiment of the present application, as Figure 3 and Figure 4 shown, at both ends of the upper and lower parts of the mold 4 that are away from each other, a boss 411 and a groove 412 are provided. The boss 411 enables the upper and lower parts of the mold 4 to be fitted into the bottom bearing structure 1 and the top pressing structure 2. The grooves 412 are distributed in a criss-cross pattern at both ends of the upper and lower parts of the mold 4 that are away from each other, and both ends of the groove 412 are arranged in a gradually spreading shape towards the outside.

[0041] Specifically, the upper part of the mold 4 is the upper mold 41, and the lower part of the mold 4 is the lower mold 42. The upper mold 41 and the lower mold 42 have the same structure except for the different structures on the mold pressing surface.

[0042] It can be seen from this that the design of the groove 412 enables one end of the upper mold 41 and the lower mold 42 facing away from each other to have a certain air-cooling effect. Specifically, an external fan can be used to provide air flow. When the air flow passes through the criss-cross grooves 412, the heat dissipation effect between the upper mold 41 and the upper cooling plate 231, and between the lower mold 42 and the lower cooling plate 131 can be enhanced. During the process of the air flow flowing through the grooves 412, the heat on the mold 4 can also be evenly dispersed to the corresponding cooling plates. At the same time, the end of the groove 412 adopts a gradually spreading structural design, so that the air flow can form a Venturi effect when flowing through it, accelerating the flow rate of the air flow in the groove 412, and then further improving the heat dissipation effect of the mold 4.

[0043] Furthermore, it can be understood that bosses 411 are respectively provided on the upper mold 41 and the lower mold 42, and they are respectively fitted into the corresponding bearing platforms 13 and the displacement ends of the pressing telescopic members 21. In this way, the stability of the upper mold 41 and the lower mold 42 can be enhanced. At the same time, especially for the lower mold 42, it can be directly fitted into the bearing platform 13 through the boss 411, reducing bolt fixation and improving the speed of its installation or disassembly.

[0044] It should be noted that serpentine coolant channels are provided inside both the upper mold 41 and the lower mold 42. Two coolant connectors 413 are respectively fixedly connected to the side walls of the upper mold 41 and the lower mold 42 and are externally connected to cooling equipment to form a coolant circulation.

[0045] Embodiment 2. Another application of the basalt fiber composite material reinforced structure provided by the embodiments of the present application includes the molding device for the basalt fiber composite material reinforced structure described above. The basalt fiber composite material reinforced structure adopts a molding process to enhance its weather resistance, wear resistance and mechanical properties.

[0046] Preferably, the molding process is applied to non-load-bearing parts of mining dump trucks, such as doors, fenders, roof covers, side plates, etc., to reduce the self-weight, improve durability and enhance the adaptability of the vehicle in extreme environments.

[0047] It should be noted that the specific model specifications of the elastic telescopic member 141, the lower cooling plate 131, the horizontal displacement assembly 15, the horizontal telescopic member 151, the downward pressing telescopic member 21, the upper cooling plate 231, the injection head 31 and the coolant joint 413 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in the art, so it will not be elaborated in detail.

[0048] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present application, and all should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
