Technical Field

[0001] The invention belongs to the technical field of mechanical processing, and in particular relates to an H-shaped composite material beam forming die. Background Art

[0002] The H-shaped composite beam is a structure with an H-shaped cross section, manufactured from composite materials. Its cross-sectional shape is similar to the H-shape of a tie rod, with a horizontal crossbeam and two vertical supporting legs. This structural design provides high strength and rigidity, and is suitable for applications that require high loads and high bending strength. During the production process, molds, usually constructed of composite materials, are required to achieve precise control of the shape and structure of the composite beam.

[0003] However, during the production process of some H-shaped composite beams through molds, the internal resin cannot be vibrated, which can easily cause excessive bubbles to form during the fusion of the internal resin and the composite material, resulting in a decrease in the overall product quality. Summary of the invention

[0057] Working principle: During use, the staff docks the resin connecting pipe with the feed port 17, deposits the resin into the feed port 17, and then starts the hydraulic rod 3. The output end of the hydraulic rod 3 drives the fixed plate 5 to move up and down. During the movement, the limit rod 4 slides inside the fixed plate 5 to increase the operating stability of the fixed plate 5.

The elliptical blocks 21 hit the bottom connecting piece 23 while rotating, and the vibration force generated by the hitting is transmitted to the hitting block 24 through the sliding column 1 22, so that the resin inside the shaping groove 2 can be vibrated to discharge the bubbles in the process of fusion of the resin and the composite material, so as to prevent the problem of residual bubbles inside the H-profile after the production is completed, causing the quality to decline, and through the hydraulic rod 3 The output end drives the fixing plate 5 to continuously descend, so that the pressing plate 28 can be docked with the inner top of the shaping groove 2, so as to protect the surface of the resin. After the molding and demolding are completed, the electric telescopic rod 30 is started, and the cleaning block 31 is driven to slide inside the shaping groove 2 by the output end of the electric telescopic rod 30, and at the same time, the cleaning sheet 33 is pushed out from the inside of the cleaning block 31 by the elastic force of the spring three 34, so that the inner wall of the shaping groove 2 can be cleaned. This design is to be able to clean the internal shaping groove 2 before use to prevent dust and impurities inside the shaping groove 2 from affecting the finished product effect of the H-beam.
