Description

Technical Field

[0001] This utility model relates to the field of composite materials and process technology, specifically to an integrated molding mold for composite material double-layer rods. Background Technology

[0002] With the advent of the "lightweight" era, composite material rods are increasingly widely used across various industries. In some fields with high strength requirements, existing single composite material rods can no longer meet performance demands. Therefore, double-layer composite material rods are of great significance. Firstly, they enhance structural stability, as the double-layer design can better withstand tensile and compressive forces. Secondly, they improve connection reliability, as the double-layer structure reduces the risk of connection failures. Furthermore, they help optimize the overall performance of composite material products, playing a crucial role in fields such as aerospace and high-end automotive manufacturing. Therefore, this utility model provides an integrated molding die for double-layer composite material rods. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides an integrated molding die for composite material double-layer rods, which solves the problems mentioned in the background.

[0004] To enable the integral molding of composite double-layer rods, this utility model achieves this through the following technical solution: an integral molding mold for composite double-layer rods, comprising two first mold templates and two second mold templates, the two first mold templates and the two second mold templates being fixedly connected by positioning screws, a base plate being fixedly installed at the bottom of the two first mold templates and the two second mold templates, an upper pressure plate being provided at the top of the two first mold templates and the two second mold templates, and an extrusion assembly and an outer mold block assembly being respectively provided on the inner walls of the two first mold templates and the two second mold templates; The extrusion assembly includes two sets of inclined pressure plates, and an inclined extrusion plate is provided on one side of the inclined side of the two sets of inclined pressure plates. The outer mold assembly includes two outer templates, and a second outer mold block is disposed between opposite sides of the two outer templates. Two mold cores are fixedly installed on the top of the second outer mold block. Double-layer rods are disposed on the outer walls of the two mold cores. Two first outer mold blocks are disposed on the top of the two double-layer rods. First inclined pressure blocks are disposed on the top of the two double-layer rods.

[0005] Preferably, two second inclined edge blocks are provided on both sides of the inclined edge of the first inclined edge block, a third inclined edge block is provided on one side of the outer wall of one of the two first outer mold blocks, and a fourth inclined edge block is provided on one side of the inclined edge of the third inclined edge block.

[0006] Preferably, a sixth inclined pressure block is provided on one side of the outer wall of one of the two first outer mold blocks, and a fifth inclined pressure block is provided on one side of the outer wall of the sixth inclined pressure block.

[0007] This invention provides an integral molding die for a composite material double-layer rod. Compared with the prior art, it has the following advantages: 1. This composite material double-layer rod integral molding mold, through the inclined surface force transmission design of multiple sets of inclined pressure blocks, transforms vertical pressure into uniform horizontal extrusion force, achieving multi-directional synchronous clamping of the double-layer rod. This avoids the product deformation problems caused by insufficient or excessive local pressure in traditional molds, ensuring that the inner and outer contour accuracy of the rod meets design requirements. The precise cooperation between the mold core and the outer mold assembly provides stable internal support and external constraint for the double-layer rod, ensuring the coaxiality and interlayer fit of the double-layer structure, and enhancing the structural stability of the product. 2. This composite material double-layer rod integral molding mold uses positioning screws to fix the first mold sleeve template, the second mold sleeve template, and the base plate. The overall structure is highly rigid, and the assembly and positioning are precise, reducing the shaking or displacement of the mold during the pressure process and extending the mold's service life. The modular design of the beveled pressure block makes the assembly and disassembly of the blocks convenient. Combined with the vertical pressure method of the pressure plate, it simplifies the operation process, reduces the difficulty of manual operation, and improves production efficiency.

Detailed Implementation

[0009] 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.

[0010] This utility model provides two technical solutions: Figures 1-8 The first embodiment is shown: a composite material double-layer rod integral molding mold, including two first mold templates 2 and two second mold templates 3, which are fixedly connected by positioning screws. A base plate 4 is fixedly installed at the bottom of the two first mold templates 2 and the two second mold templates 3, and an upper pressure plate 1 is provided at the top of the two first mold templates 2 and the two second mold templates 3. An extrusion component 5 and an outer mold block component 6 are respectively provided on the inner wall of the two first mold templates 2 and the two second mold templates 3. The extrusion assembly 5 includes two sets of inclined pressure plates 51. An inclined extrusion plate 52 is provided on one side of the inclined side of the two sets of inclined pressure plates 51. When the upper pressure plate 1 presses the inclined pressure plate 51 downward, the inclined side allows the two inclined extrusion plates 52 to press laterally. The outer mold assembly 6 includes two outer templates 61. A second outer mold block 611 is provided between the opposite sides of the two outer templates 61. Two mold cores 610 are fixedly installed on the top of the second outer mold block 611. Double-layer rods 69 are provided on the outer walls of the two mold cores 610. Two first outer mold blocks 68 are provided on the top of the two double-layer rods 69. A first inclined pressure block 62 is provided on the top of the two double-layer rods 69.

[0011] Figures 1-8 The second embodiment is shown. The main difference from the first embodiment is that: two second inclined edge pressure blocks 63 are provided on both sides of the inclined edge of the first inclined edge pressure block 62. When the first inclined edge pressure block 62 is subjected to a downward force, it will simultaneously squeeze the second inclined edge pressure blocks 63 on both sides. A third inclined edge pressure block 64 is provided on one side of the outer wall of one of the two first outer mold blocks 68. A fourth inclined edge pressure block 65 is provided on one side of the inclined edge of the third inclined edge pressure block 64. When the fourth inclined edge pressure block 65 is subjected to a downward force, it will be transmitted to the third inclined edge pressure block 64 through the inclined edge. The third inclined edge pressure block 64 can thus squeeze the first outer mold block 68, so that the double-layer rod 69 can be formed.

[0012] One of the two first outer mold blocks 68 has a sixth inclined edge pressure block 67 on one side of its outer wall, and a fifth inclined edge pressure block 66 is provided on one side of the outer wall of the sixth inclined edge pressure block 67.

[0013] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0014] During operation, the raw material of the composite double-layer rod 69 is first wrapped around the outer walls of two mold cores 610 according to the design requirements. The mold cores 610 serve as internal support structures, precisely defining the inner contour dimensions of the rod and providing a reference for subsequent molding. The first outer mold block 68 is placed at the corresponding position at the top of the double-layer rod 69, and the first inclined edge pressure block 62, the second inclined edge pressure block 63, the third inclined edge pressure block 64, the fourth inclined edge pressure block 65, the fifth inclined edge pressure block 66, and the sixth inclined edge pressure block 67 are assembled in sequence. These blocks together constitute the preliminary constraint structure for the external molding of the rod. Then, the inclined edge pressure plate 51 and the inclined edge extrusion plate 52 are placed on one side of the outer wall of the two outer mold templates 61. The pressure application device is activated, and the upper pressure plate 1 applies pressure downward in the vertical direction. This pressure acts simultaneously on the first inclined edge pressure block 62 in the outer mold block assembly 6 and the inclined edge pressure plate 51 of the extrusion assembly 5. For the outer mold assembly 6, after the first inclined pressure block 62 is subjected to vertical pressure, it transmits the force to the second inclined pressure block 63 through its inclined structure, which is converted into horizontal extrusion force. Similarly, the fourth inclined pressure block 65 extrudes the third inclined pressure block 64 and the fifth inclined pressure block 66 extrudes the sixth inclined pressure block 67 to produce horizontal displacement. Multiple sets of inclined pressure blocks work together to extrude from the top and sides of the rod towards the center. For the extrusion assembly 5, under the action of vertical pressure, the inclined plate 51 transmits the force to the inclined extrusion plate 52 through the inclined surface, so that the inclined extrusion plate 52 generates a horizontal inward thrust, which directly acts on the outer wall of the two outer templates 61.

[0015] Under the horizontal thrust of the extrusion assembly 5, the outer template 61 moves inward, thereby causing the second outer template block 611 on its inner side to tighten towards the center in sync. Under the action of horizontal extrusion force, each inclined pressure block in the outer mold assembly 6 continuously approaches, forming a synergistic effect with the outer template 61 and the second outer mold assembly 611, applying uniform pressure from all sides of the double-layer rod 69.

[0016] The mold core 610 serves as an internal support, working in conjunction with the extrusion action of the external blocks to ensure that the raw material of the double-layer rod 69 adheres tightly to the contours of the mold core 610 and the outer mold under multi-directional pressure, thus completing the curing process. After molding, the pressure of the upper pressure plate 1 is removed, and the inclined pressure blocks and extrusion components 5 are reset, allowing the molded double-layer rod 69 to be removed.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
