Description

Technical Field

[0001] This utility model belongs to the field of mold technology, and specifically relates to a mold structure for a rotating shaft structure product. Background Technology

[0002] Some carbon fiber products have pivot structures that require shaft holes, such as high-speed rail skirt components. These components are made using a carbon fiber prepreg molding process, and because the product involves flipping, a pivot structure is necessary. Therefore, the coaxiality of the pivot must be accurate. Otherwise, the product will be unusable and rendered unusable.

[0003] Currently, drilling is generally used for machining. However, because the structure has a certain length, machining with a drill bit not only fails to guarantee coaxiality, but also places extremely high demands on the length of the drill bit, making it impossible to guarantee product precision. Summary of the Invention

[0004] This utility model provides a mold structure for a rotating shaft product, which can solve the problems pointed out in the background art.

[0005] A mold structure for a rotating shaft product includes a mold body, which includes an upper mold, a lower mold, and a mold cavity formed between the upper and lower molds. A rotating shaft forming rod is provided at the edge of the mold cavity of the lower mold. Limiting and clamping devices at both ends of the rotating shaft forming rod are used for clamping and limiting. The limiting and clamping devices are located on both sides outside the mold cavity. A supporting and limiting component is provided at a corresponding position inside the mold cavity. The supporting and limiting component is used for limiting and supporting the rotating shaft forming rod.

[0006] Preferably, the limiting and pressing device includes a pressing block and a pressing groove disposed at the bottom of the pressing block and matching the rotating shaft forming rod, wherein the pressing block is pressed onto the lower mold by a first bolt.

[0007] Preferably, the support limiting component includes an embedded block and a limiting groove connected to the embedded block, and the lower mold is provided with an embedded groove corresponding to the embedded block at a corresponding position, and the embedded block is fixed in the embedded groove by a second bolt.

[0008] Beneficial effects: This utility model provides a mold structure for a rotating shaft product, which eliminates the need for subsequent drilling, has high coaxiality accuracy, good molding quality, saves manpower and resources, improves work efficiency, and increases the first-pass yield of products.

Detailed Implementation

[0010] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0011] Example 1: As Figure 1-2 As shown in the figure, the mold structure of a rotating shaft structure product provided by this utility model includes a mold body, the mold body includes an upper mold 1, a lower mold 2 and a mold cavity formed between the upper mold 1 and the lower mold 2, a rotating shaft forming rod 3 is provided at the edge of the mold cavity of the lower mold 2, and the rotating shaft forming rod 3 is clamped and limited by limiting and pressing devices 4 at both ends of the rotating shaft forming rod 3. The limiting and pressing devices 4 are located on both sides outside the mold cavity, and a support limiting component 5 is provided at the corresponding position inside the mold cavity. The support limiting component 5 is used for limiting and supporting the rotating shaft forming rod 3.

[0012] Specifically, the limiting and pressing device 4 includes a pressing block 41 and a pressing groove 42 provided at the bottom of the pressing block 41 that matches the rotating shaft forming rod 3. The pressing block 41 is pressed onto the lower mold 2 by a first bolt 43, and the pressing block 41 is pressed and fixed by the first bolt 43. The pressing groove 42 presses against the end of the rotating shaft forming rod 3 to press and limit its movement. The supporting and limiting component 5 includes an embedded block 51 and a limiting groove 52 connected to the embedded block 51. The lower mold 2 is provided with an embedded groove 21 corresponding to the embedded block 51 at a corresponding position. The embedded block 51 is fixed in the embedded groove 21 by a second bolt 53.

[0013] The general operation steps of this utility model are as follows: After the material is wrapped and laid by the rotating shaft forming rod 3, it is placed into the mold cavity of the lower mold 2. The rotating shaft forming rod 3 is pressed and limited on the lower mold 2 by the limiting and clamping devices 4 at both ends. The mold is closed to perform molding. After the material cools and solidifies, the molded product can be taken out.

[0014] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
