Abstract
Description
Technical Field
[0001] This utility model relates to the field of mast forming tooling technology, and in particular to a composite material mast forming tooling. Background Technology
[0002] Composite masts typically employ carbon fiber reinforced composites or glass fiber reinforced composites. Carbon fiber offers higher strength and lower density, but at a higher cost; glass fiber, on the other hand, has advantages in terms of cost and corrosion resistance. Currently, traditional composite mast forming tooling suffers from numerous problems. In terms of structural design, most tooling struggles to simultaneously and precisely control the forming of the mast's inner and outer surfaces. Furthermore, for forming special structures such as the mast top through-hole, flanged area, and tailpipe bottom, traditional tooling often requires additional auxiliary molds or complex processing techniques. This not only increases the tooling's manufacturing cost and production cycle but also easily leads to cumulative errors due to repeated clamping and positioning, making it difficult to meet the demands of modern high-precision manufacturing.
[0003] In terms of operational procedures, the prepreg layup process of traditional tooling relies on manual experience and lacks standardized layup sequences and positioning methods, resulting in inconsistent layup quality across different batches. Furthermore, the assembly and connection methods of various tooling components are complex, leading to low efficiency in positioning and fixing components during mold closing, hindering rapid and accurate assembly and severely impacting production efficiency. In addition, during the hot pressing process, the unreasonable mold structure design and uneven heat and pressure distribution can easily lead to inconsistent curing degrees of the composite material, resulting in defects such as deformation and delamination, further reducing the product qualification rate. In summary, existing composite mast molding tooling has shortcomings in both structural design and operational procedures, failing to meet the high-precision and high-efficiency manufacturing requirements of composite masts. Therefore, a new type of composite mast molding tooling with a reasonable structure, convenient assembly, and precise control over the molding quality of each part of the mast is needed. Summary of the Invention
[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a new type of composite material mast forming tooling that is structurally reasonable, easy to assemble, and capable of precisely controlling the forming quality of each part of the mast.
[0005] The technical solution of this utility model is: a composite material mast forming tooling, including a tooling body and a formed part, the formed part including a top end of the formed mast located at the top and a rolled edge of the outer ring of the bottom of the formed mast, the tooling body including an upper mold and a lower mold, and forming cavities for forming the formed part are opened at corresponding positions of the upper mold and the lower mold.
[0006] The bottom of the upper mold and the lower mold is provided with a base plate, and a baffle is provided inside the base plate;
[0007] The upper and lower molds are equipped with auxiliary demolding components for assisting demolding. The auxiliary demolding components include abutting blocks that abut against the demolding and screws for the lifting and lowering movement of the abutting blocks.
[0008] Optionally, both the upper and lower molds are provided with adjustment cavities for assisting in the installation of demolding components. The adjustment cavity includes an upper cavity and a lower cavity, and a fixing plate is fixedly connected to the inner wall of the lower cavity.
[0009] Optionally, the screw is rotatably mounted in the upper cavity, and one end of the screw is fixedly connected to an abutment rod;

[0011] Optionally, a connecting rod that penetrates the fixing plate is fixedly connected to the bottom of the contact block, and the bottom end of the connecting rod is fixedly connected to the top of the contact block.
[0012] Optionally, a spring is connected to the fixing plate, the top end of the spring is connected to the bottom of the contact block, and the spring is sleeved on the outer ring of the connecting rod.
[0013] Optionally, the tooling body also includes a pin that is disposed inside the top end of the forming mast and connected to the forming cavity.
[0014] Optionally, the tooling body further includes a core mold disposed inside the molded part, and the base plate is assembled with the upper mold, lower mold and core mold by screws.
[0015] Compared with the prior art, the present invention has the following beneficial technical effects:
[0016] The main body of this utility model tooling ensures the size of the product, avoids the loss of composite material strength caused by secondary machining, and also reduces machining steps. It has high molding efficiency, high product consistency, and can meet the needs of various irregularly shaped products. It adopts a press molding process, and the size of the mast product is guaranteed by the mold. No secondary machining is required in the later stage, which ensures the strength of the composite material, improves work efficiency, reduces material waste, and lowers costs.
[0017] This utility model provides auxiliary demolding components at the contact surfaces of the upper and lower molds with the base plate. By rotating the screw, the abutment block is pushed out of the lower cavity, thereby assisting in the demolding of the molded part. With the help of springs and other components for buffering and guiding, damage to the mast is avoided during demolding, thus improving the product qualification rate and production efficiency.
[0018] In summary, the components of this utility model are assembled with screws, which facilitates disassembly, maintenance, and mold replacement, effectively reducing usage costs and meeting the diverse production needs of composite material masts. Attached Figure Description

The fixture body includes an upper mold 1 and a lower mold 2. A molding cavity 10 for molding the molded part 5 is opened at the corresponding positions of the upper mold 1 and the lower mold 2. The fixture body also includes a pin 3 disposed in the top end 51 of the molded mast and connected to the molding cavity 10.
[0039] The bottom of the upper mold 1 and the lower mold 2 are provided with a base plate 7. The main body of the tooling also includes a core mold 4 set inside the molding part 5. The base plate 7 is assembled with the upper mold 1, the lower mold 2 and the core mold 4 by screws. A baffle 6 is provided inside the base plate 7. The baffle 6 is consistent with the product's flange structure.
[0040] Combination Figure 3 As shown, the upper mold 1 and the lower mold 2 are equipped with auxiliary demolding components 8 for assisting demolding, and both the upper mold 1 and the lower mold 2 are provided with adjustment cavities 9 for installing the auxiliary demolding components 8.
[0041] In this embodiment, the upper mold 1 and the lower mold 2 are used to form the outer surface of the mast, which is consistent with the outer shape of the product. They are connected to the base plate 7 by positioning pins. The core mold 4 is used to form the inner surface of the part 5, which is consistent with the inner shape of the product. It is connected to the base plate 7 by screws. The pin 3 is used to be installed inside the top end 51 of the mast and has an assembly relationship with the upper mold 1 and the lower mold 2.
[0042] In this embodiment, the prepreg is cut to size using a fabric cutting machine according to the product structure. The cut prepreg is then laid on the molding part 5 and the base plate 7 in a certain order. After the laying is completed, the upper mold 1 and the lower mold 2 are assembled on the base plate 7 and placed on a press. Pressure and heating are then applied. After the upper mold 1 and the lower mold 2 are closed, the components are connected with screws.
[0043] Example 2
[0044] like Figure 1 and Figure 3 As shown, based on Embodiment 1, the auxiliary demolding component 8 includes an abutment block 85 for abutting and assisting demolding, and a screw 81 for lifting and moving the abutment block 85. Combined with the drive of the abutment block 85 to push out the lower cavity 92, the molded part 5 is assisted in demolding, avoiding violent removal. The screw 81 is screwed and rotated in the upper cavity 91. One end of the screw 81 is fixedly connected to an abutment rod 82, and a contact block 83 is provided on one side of the abutment rod 82.
