Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a composite material cone-shaped mold. Background Technology

[0002] As the trend of "lightweighting" sweeps across all industries, traditional metallic materials are proving insufficient in weight-sensitive fields such as aerospace and precision instruments. For example, in the interstage sections of rockets or the conical load-bearing structures of satellites, the weight of metallic components often becomes a bottleneck restricting performance improvement. Therefore, composite conical structures, with their dual advantages of high strength and low density, have become an ideal alternative.

[0003] The core of this technological innovation lies in a novel composite material cone-shaped molding die. Through precise design, this die ensures accurate layup and curing of the composite material on complex conical structures, thereby efficiently and stably manufacturing high-performance, lightweight cone-shaped products. This not only significantly reduces structural weight but also enhances overall strength and load-bearing capacity, providing solid technical support for the breakthrough development of high-end equipment manufacturing. Therefore, this invention provides a composite material cone-shaped molding die. Summary of the Invention

[0004] This utility model is achieved through the following technical solution: a composite material cone-shaped mold, including two first side plates and two second side plates, with a bottom plate at the bottom of the two first side plates and the two second side plates. The bottom plate, the two first side plates and the two second side plates are fixed together by screws to form a mold frame. The mold frame is provided with four outer mold blocks inside, and a core mold is provided inside the four outer mold blocks. Upper and lower pressure plates are provided on both sides of the outer wall of the four outer mold blocks.

[0005] Preferably, a second inclined edge pressure block is provided on both sides of the outer wall of the four outer mold blocks, and a first inclined edge pressure block is attached to one side of the inclined edge of each of the two second inclined edge pressure blocks.

[0006] Preferably, a third inclined edge pressure block is attached to the outer wall of both upper and lower pressure plates, and a fourth inclined edge pressure block is attached to one side of the inclined edge of each of the two third inclined edge pressure blocks.

[0007] Preferably, a top cover plate is provided at the top of the two first side plates and the two second side plates.

[0008] This utility model provides a composite material cone-shaped mold. Compared with the prior art, it has the following advantages: (1) The composite material cone barrel molding mold, through the mold frame consisting of the base plate, side plate and screws, provides a stable external frame structure for the entire mold, which can effectively ensure the overall stability of the mold during the mold closing and molding process, prevent the mold from deforming, and thus ensure the molding accuracy of the composite material cone barrel. The setting of the inclined side pressure block and the upper and lower pressure plates can make the pressure during mold closing evenly transmitted to the four outer mold blocks, and then evenly act on the composite material on the core mold, which helps to improve the density and uniformity of the composite material cone barrel, reduce internal defects, and improve product quality.

[0009] (2) The composite material cone molding die has a relatively simple assembly and disassembly process. The structure of each component is reasonably designed, which makes it easy for operators to install, debug and maintain it daily, which is conducive to improving production efficiency and reducing production costs.

Detailed Implementation

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0012] This utility model provides two technical solutions: Figures 1-5 The first embodiment is shown: a composite material cone-shaped mold, including two first side plates 1 and two second side plates 2. A bottom plate 4 is provided at the bottom of the two first side plates 1 and the two second side plates 2. The bottom plate 4, the two first side plates 1 and the two second side plates 2 are fixed together by screws to form a mold frame. Four outer mold blocks 9 are provided inside the mold frame. A core mold 10 is provided inside the four outer mold blocks 9. Upper and lower pressure plates 11 are provided on both sides of the outer wall of the four outer mold blocks 9.

[0013] Figures 1-5The second embodiment is shown. The main difference from the first embodiment is that: a second inclined edge pressure block 6 is provided on both sides of the outer wall of the four outer mold blocks 9, and a first inclined edge pressure block 5 is attached to one side of the inclined edge of the two second inclined edge pressure blocks 6. When the first inclined edge pressure block 5 is pressed downward, it will apply pressure to the second inclined edge pressure block 6 through the inclined edge, thereby pressing the outer mold block 9.

[0014] The outer walls of the two upper and lower pressure plates 11 are fitted with third inclined pressure blocks 7, and the inclined sides of the two third inclined pressure blocks 7 are fitted with fourth inclined pressure blocks 8. When the fourth inclined pressure block 8 is pressed downward, it will press the third inclined pressure block 7 through the inclined side, thereby pressing the other two sides of the outer mold assembly block 9.

[0015] A top cover plate 3 is provided at the top of the two first side plates 1 and the two second side plates 2.

[0016] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0017] In use, firstly, the composite material is laid up on the outer wall of the core mold 10 according to the design requirements of the composite cone barrel, so that the product is initially formed and attached to the core mold 10. During this process, the core mold 10, as an internal support structure, directly determines the inner contour dimensions of the cone barrel to be formed later. Next, the four outer mold blocks 9 are spliced ​​around the core mold 10 to form the forming cavity outside the cone barrel. At the same time, the upper and lower pressure plates 11 are respectively attached to the two sides of the outer wall of the four outer mold blocks 9 to build a basic structure for the uniform transmission of pressure later. Then, the base plate 4 is placed horizontally as the basic support of the entire mold. Then, the two first side plates 1 and the two second side plates 2 are respectively fastened to the edge of the base plate 4. The three are fixedly connected by screws through the connection holes between the base plate 4 and the first side plate 1, and between the base plate 4 and the second side plate 2, and assembled into a mold frame with rigid support. This mold frame can prevent the overall deformation of the mold during subsequent pressure application and provide a stable installation and working space for the internal forming components. After that, the assembled "core mold 10 + outer mold blocks 9 + The upper and lower pressure plates 11” are slowly placed into the fixed mold frame. The position is adjusted so that there is no significant gap between the outer walls of the four outer mold blocks 9 and the inner walls of the mold frame (i.e., the inner walls of the two first side plates 1 and the two second side plates 2). This ensures that the outer mold blocks 9 will not shift laterally during subsequent pressure application, further guaranteeing the shape accuracy of the cone. Then, the pressure blocks are installed in a specific sequence: first, the second inclined pressure blocks 6 are attached to both sides of the outer walls of the four outer mold blocks 9; then, the first inclined pressure blocks 5 are attached to the inclined sides of the two second inclined pressure blocks 6, ensuring complete contact between their inclined surfaces for effective pressure transmission; simultaneously, the third inclined pressure blocks 7 are attached to the outer walls of the two upper and lower pressure plates 11; and then the fourth inclined pressure blocks 8 are attached to the inclined sides of the two third inclined pressure blocks 7, so that all the inclined pressure blocks form a complete “vertical pressure to horizontal pressure” conversion. The transfer channel; finally, the top cover plate 3 is placed on top of the two first side plates 1 and the two second side plates 2. A downward vertical pressure is applied to the top cover plate 3 by an external pressure device such as a hydraulic press. This pressure is simultaneously transferred to the first inclined side pressure block 5 and the fourth inclined side pressure block 8. Under pressure, the first inclined side pressure block 5 pushes the second inclined side pressure block 6 to move horizontally inward along the inclined surface. The second inclined side pressure block 6 then squeezes the outer mold assembly 9. At the same time, under pressure, the fourth inclined side pressure block 8 pushes the third inclined side pressure block 7 to move horizontally inward along the inclined surface. The third inclined side pressure block 7 further transfers the extrusion pressure to the outer mold assembly 9 through the upper and lower pressure plates 11. Under the coordinated extrusion of multiple sets of inclined side pressure blocks, the four outer mold assembly blocks 9 tightly wrap the composite material on the core mold 10, providing uniform and continuous molding pressure for the composite material curing process. Combined with the appropriate temperature provided by the external curing equipment, the composite material is finally completely cured and molded into a composite material cone that meets the design dimensions and performance requirements.
