[0016] 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.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Reference Figures 1 to 3As shown, this embodiment provides a composite material device molding die for fixing a servo motor, including a lower die 1. A temperature measuring hole 2 is provided on one side of the lower die 1. Positioning guide posts 3 are provided at the four corners of the top surface of the lower die 1. Positioning pins 4 are provided on the top surface of the lower die 1. A first module 5 is installed on the positioning pins 4. A second module 6 and a third module 7 are respectively installed on the first module 5. A first movable block 8 is provided on the side of the first module 5 near the temperature measuring hole 2. A second movable block 9 and a third movable block 10 are respectively provided on the side of the first module 5 away from the temperature measuring hole 2. An upper die is installed on the positioning guide posts 3.

[0019] First, the inner skins of modules 5, 6, and 7 are individually laid. Then, the three laid modules are installed on the lower mold 1. Fibers are placed outside the inner skins, and the outer skins are then laid before the molds are closed. During the laying process, mold assistance and multiple vacuum pre-compaction processes can be used to ensure the size and density of the laid product. This utility model uses a molding process to manufacture carbon fiber composite materials, which can ensure the interlayer bonding of the composite material and improve the production quality and dimensional requirements of the fixing device.

[0020] Temperature sensor 2 is mainly used to detect the temperature of the mold, which facilitates the control of the pressing time, pressing pressure and temperature control in the compression molding process, thereby reducing internal quality problems of the product.

[0021] The scheme was further optimized by laying inner skin on the outer side of the first module 5, the second module 6 and the third module 7 respectively, filling the inner skin with fibers, and providing an outer skin on the outer side of the fibers.

[0022] The design was further optimized, with the first module 5, the second module 6, and the third module 7 each fixed to the lower mold 1 using screws 11. This ensures accurate positioning of each module on the lower mold.

[0023] The design was further optimized by adding a lifting ring hole 12 to the lower mold 1. This hole is used to assist in mold closing.

[0024] The design was further optimized by adding mold release grooves 13 on both sides of the lower mold 1. This facilitates demolding after the mold is closed.

[0025] The scheme is further optimized so that the second live block 9 abuts against the first live block 8 and the second live block 9 respectively.

[0026] During molding, inner skins can be laid on each module separately, followed by the placement of movable blocks. During molding, pressure can be applied to the outer surface of the composite material using 95° movable blocks, ensuring the integrity of the product's inner and outer surfaces and improving product performance. Demolding is simple and convenient, minimizing the risk of product damage. During demolding, the positioning pins 4 and bolts can be removed gradually, dismantling each module without damaging the product surface. The upper and lower mold structure 1, composed of multiple movable blocks, ensures the surface quality of the product, reduces molding difficulty, and guarantees product precision requirements through the molding process. By designing the mold gap and controlling the movable block positioning method, the risk of poor bonding between multi-curved layers is reduced.

[0027] A method of using a composite material device molding die for fixing a servo motor includes the following steps:

[0028] S1. First, lay the inner skin of the first module 5, the second module 6 and the third module 7 separately. Then, place the first module 5 on the positioning pin 4 and tighten the screws on each module to ensure that each module is accurately positioned on the lower mold 1.

[0029] S2. Check the gap between modules on the modules installed in step S1, fill them with fiber, then lay the outer skin as a whole, and place the first movable block 8, the second movable block 9 and the third movable block 10 respectively to limit the product size and protect the product's outer surface.

[0030] S3. Perform mold closing, align the positioning guide post 3, and close the upper and lower molds 1 together, with the lifting ring assisting in mold closing;

[0031] S4. After the mold is closed, the product enters the press to cure. Using temperature measuring hole 2, the temperature is measured when the mold is heated to near the gel point. The temperature is then maintained for 30 minutes. At this time, the resin on the product has good fluidity.

[0032] S5. Continue heating and heat preservation for curing;

[0033] S6. Cool to room temperature, demold and trim to obtain a product that meets the requirements.
