Description

Technical Field

[0001] The utility model relates to the field of perfusion equipment, and more specifically, to a composite material type rubber baffle. Background Art

[0002] Blade infusion molds are key equipment used in the manufacture of composite blades and large structural components. They require complex shapes, high-precision manufacturing, and multiple functions such as sealing, venting, infusion, and demolding. Proper design and use of blade infusion molds can significantly improve the molding quality and production efficiency of composite structural components.

[0003] The glue baffle in a blade infusion mold is a critical component used to control the flow of glue and seal the mold opening during composite blade manufacturing. Its primary function is to prevent glue leakage during infusion, ensuring even distribution within the mold cavity while allowing necessary venting.

[0004] However, the design of the rubber baffle in the existing technology is usually too complicated and cannot be perfectly adapted to the opening of the blade infusion mold with two curved surface segments. It also has low strength and is easy to deform, affecting the infusion processing effect. In addition, due to the poor adaptation effect, the sealing performance after installation is general, and sealing failure is prone to occur. Moreover, the existing rubber baffle has a single structure and cannot detect the density or tightness of the glue poured inside the infusion mold. Utility Model Content

DETAILED DESCRIPTION

[0030] In order to make the technical solutions in the embodiments of the utility model clearer and more complete, the following will be combined with the drawings in the embodiments of the utility model to make a clear and complete description of the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0031] It should be understood that the terms such as "have", "contain" and "include" used in this paper do not exclude the presence or addition of one or more other elements or combinations thereof.

[0032] Please refer to Figure 1-7 , the utility model provides a technical scheme:

[0033] A composite material glue baffle comprises: a glue baffle body 100 for sealingly fitting and connecting to an opening of a blade infusion mold 200, which can be bonded using mold glue, with a perfusion cavity for perfusing glue formed between the glue baffle body 100 and the blade infusion mold 200; the glue baffle body 100 comprises: a first curved plate portion 101, a second curved plate portion 102, and a straight plate portion 103, the two ends of the second curved plate portion 102 being connected to the first curved plate portion 101 and the straight plate portion 103, respectively; the first curved plate portion 101, the second curved plate portion 102, and the straight plate portion 103 being sealingly fitting to a first curved surface segment, a second curved surface segment, and a straight surface segment of the opening of the blade infusion mold 200, respectively; and one or more perfusion detection units 300 are mounted on the straight plate portion 103.

[0034] The working principle and technical effects of the above technical solution are as follows:

[0035] The utility model provides a composite material type rubber baffle, in which the first curved plate portion 101, the second curved plate portion 102 and the straight plate portion 103 of the rubber baffle body 100 are respectively sealed and matched with the first curved surface segment, the second curved surface segment and the straight surface segment at the opening of the blade infusion mold 200, so as to achieve effective adaptation to the opening of the blade infusion mold having the first curved surface segment, the second curved surface segment and the straight surface segment, and can adapt to complex mold opening shapes, thereby improving the flexibility and versatility of the seal, having good sealing stability, and being less likely to have the problem of sealing failure; and the combination of the first curved plate portion 101, the second curved plate portion 102 and the straight plate portion 103 optimizes the flow path of the glue in the infusion cavity, ensuring that the glue is evenly distributed; by optimizing the flow path and the sealing design, it is helpful to reduce bubbles generated during the flow of the glue, thereby improving the quality of the molded parts.

[0036] The first and second curved plate portions 101, 102 have different bending directions; the convex end of the first curved plate portion 101 faces the inside of the blade infusion mold 200, while the concave end of the second curved plate portion 102 faces the inside of the blade infusion mold 200. These different bending directions not only allow the rubber baffle body 100 to better adapt to the various shapes and sizes of blade infusion mold 200 openings, but also provide improved deformation resistance. During the infusion process, the pressure generated can be more evenly distributed. Especially during high-pressure infusion, the different bending directions can avoid localized stress concentration and improve pressure resistance.

[0037] The bending radius of the first arc-shaped plate portion 101 is 38.36 mm.

[0038] The bending radius of the second arc-shaped plate portion 102 is 8.4 mm.

[0039] The height of the straight section is 30 mm.

[0040] An end of the first curved plate portion 101 away from the second curved plate portion 102 is provided with a rounded corner.

[0041] An end of the straight plate portion 103 away from the second curved plate portion 102 is rounded.

[0042] The first curved plate portion 101, the second curved plate portion 102 and the straight plate portion 103 are an integrally formed structure, and are all made of PETG composite material, and are all transparent plates.

[0043] The first curved plate portion 101, the second curved plate portion 102 and the straight plate portion 103 are an integrally formed structure, which reduces the number of connection points between the parts, reduces the potential risk of breakage and failure, improves the strength and rigidity of the overall structure, eliminates stress concentration at the connection parts, makes the overall structure more continuous and stable, and can better resist the stress and deformation generated during the infusion process; reduces potential leakage points, and helps to improve the overall sealing performance; the first curved plate portion 101, the second curved plate portion 102 and the straight plate portion 103 are all PETG transparent plates with good transparency, which is convenient for real-time observation of the flow state and filling status of the glue during the infusion process, thereby improving the visibility and accuracy of the operation; and the PETG material has good chemical corrosion resistance, can resist the chemical components in the infusion glue, and reduces the risk of material aging and deformation.

[0044] Multiple staggered transverse and longitudinal reinforcing ribs are evenly arranged on the outer surface of the rubber baffle body 100, away from the blade infusion mold 200. The staggered arrangement of the transverse and longitudinal reinforcing ribs significantly increases the overall rigidity of the rubber baffle body 100. The transverse and longitudinal reinforcing ribs provide additional support structure, allowing the rubber baffle body 100 to effectively resist external stress and deformation, thereby improving the structural strength of the rubber baffle body 100. The staggered transverse and longitudinal reinforcing ribs also help to evenly distribute the stress generated during the infusion process, preventing localized stress concentration and thus reducing the risk of fracture and failure. In addition, the increased structural support points improve the fatigue resistance of the rubber baffle body 100. During multiple infusion processes, the reinforcing ribs can better withstand cyclic stress and extend its service life.

[0045] The infusion detection unit 300 includes: a sleeve 301 fixed on the side of the straight plate portion 103 away from the blade infusion mold 200, a detection slide rod 302 sealed and slidably connected inside the sleeve 301, the detection slide rod 302 passes through the through hole on the straight plate portion 103, and one end of the detection slide rod 302 inserted into the blade infusion mold 200 is fixedly connected to a disc stopper 303, and a circular groove is provided on the straight plate portion 103 for sealing and plugging with the disc stopper 303, and one end of the detection slide rod 302 away from the blade infusion mold 200 is fixedly connected to a movable seat plate 304, and a plurality of tensioning spring bodies 305 are fixed between the movable seat plate 304 and the outer side surface of the straight plate portion 103; and scale lines are provided on the detection slide rod 302.

[0046] When the glue poured into the blade pouring mold 200 reaches a preset amount and is filled tightly, pressure will be generated on the disc stopper 303, causing the disc stopper 303 to be retracted into the circular groove. The inner side surface of the disc stopper 303 and the inner side surface of the straight plate portion 103 form a complete plane, which does not affect the quality of the product in the blade pouring mold 200. When the disc stopper 303 is retracted into the circular groove, it drives the detection slide bar 302 to slide outward in the sleeve 301 and stretch the multiple tensioning spring bodies 305. When the detection slide bar 302 overcomes the elastic force of the multiple tensioning spring bodies 305 and moves outward to a preset distance, the tightness of the glue poured in the blade pouring mold 200 can be judged. When the glue poured in the blade pouring mold 200 is not tight enough, the length of the detection slide bar 302 cannot reach the preset length.

[0047] When the glue in the blade infusion mold 200 reaches the preset amount and is tightly filled, the glue exerts pressure on the disc stopper 303, forcing it to retract into the circular groove. When the disc stopper 303 retracts, it drives the detection slide 302 to slide outward within the sleeve 301, stretching the tensioning spring 305. If the sliding distance of the detection slide 302 reaches the preset scale, the glue is tightly filled; if it does not reach the preset scale, the glue is not tightly filled. This system can automatically detect the tightness of the glue filling without manual intervention, improving detection efficiency and accuracy. The detection structure is relatively simple and easy to manufacture and maintain. The scale lines on the detection slide 302 make the test results intuitive, allowing operators to quickly determine the tightness of the glue filling. The design of multiple tensioning springs 305 effectively absorbs and releases external forces, ensuring stable and reliable detection. This system is suitable for blade infusion molds of various sizes and types, and has strong versatility and adaptability.
