Among them, the carbon fiber material used on bicycle frames can endow bicycles with lighter mass, stronger maneuverability and riding comfort, and has a large market.

By setting the limit component 6, it is possible to conveniently limit and fix the positions of the upper mold 4 and the lower mold 5, improve the stability during the injection molding of the mold, and integrally form the frame at one time through injection molding, reducing the processing steps and time required by traditional welding, assembly and other methods, and avoiding the situation that the welded part is deformed and damaged during use, improving the production efficiency and the use quality of the integral forming of the frame.
[0028] In an embodiment of the present utility model, a vibration component 7 is arranged on the lower end surface of the lower mold 5;
[0029] The vibration assembly 7 includes a motor 701 fixedly connected to the upper end surface of the workbench 1. The output end of the motor 701 is fixedly connected with a connecting rod 702. Symmetrically arranged on both sides of the surface of the connecting rod 702 are triangular blocks 703. The triangular blocks 703 include a connecting portion 7031, and a number of protruding portions 7032 are arranged at equal intervals on the surface of the connecting portion 7031. The surface of the triangular block 703 abuts against the lower end surface of the upper mold 4. The upper end surface of the fixed box 603 is fixedly connected with a spring 605, and the other end of the spring 605 is fixedly connected with a fixing plate 606. One side of the fixing plate 606 is fixedly connected to the support plate 2. By providing the vibration assembly 7, when shrinkage and warping occur during the injection molding process, the rotation of the triangular block 703 can continuously jack up the lower mold 5, and at the same time, the elasticity of the spring 605 is used to reset the positions of the upper mold 4 and the lower mold 5, thereby forming a small-amplitude vibration limited by the length of the spring 605, enabling the injection liquid to flow flat in the mold cavity, allowing the injection liquid to flow into the mold cavity more fully, and improving the injection molding effect and the integrity of the frame molding.
[0030] Working principle: This embodiment provides an integrated molding device for a carbon fiber bicycle frame. When in use, first move the upper mold 4 and the lower mold 5 towards each other so that the upper mold 4 and the lower mold 5 can slide to the central symmetry of the chute at the same time. At this time, by rotating the threaded rod 604 clockwise, the limiting frame 602 is driven to move towards the upper mold 4 and the lower mold 5, and the surface of the limiting frame 602 is clamped in the limiting hole to fix the positions of the upper mold 4 and the lower mold 5. At this time, through the operation of the motor 701, the connecting rod 702 is driven to rotate, causing the triangular block 703 to rotate continuously. During the rotation process, the connecting portion 7031 and the protruding portion 7032 are respectively and sequentially in contact with the lower surface of the lower mold 5. When the protruding portion 7032 contacts the lower surface of the lower mold 5, the upper mold 4, the lower mold 5 and the limiting component 6 are driven to squeeze the spring 605 upwards by its convex surface. Subsequently, the smooth surface of the connecting portion 7031 contacts the lower surface of the lower mold 5, thereby canceling the upward jacking of the lower surface of the lower mold 5, causing the spring 605 to reset and drive the upper mold 4 and the lower mold 5 to reset. Thus, through the continuous rotation of the triangular block 703, a small-amplitude vibration of the upper mold 4 and the lower mold 5 is formed, improving the leveling effect of the injection liquid.
