Detailed Implementation

[0021] 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.

[0022] This utility model provides, for example Figures 1-2 The winding mold with a sealing groove shown includes:

[0023] The first winding mold 105 and the second winding mold 109 together form a composite winding mold for composite material forming. This allows two composite winding molds to be combined into one for use. When using the mold composed of the first winding mold 105 and the second winding mold 109 for composite material forming, the forming of two composite materials can be completed in one operation, improving work efficiency. The opposite sides of the first winding mold 105 and the second winding mold 109 have mutually fitting concave-convex shapes, and the mating surfaces of the first winding mold 105 and the second winding mold 109 also have mutually fitting concave-convex surfaces, which not only ensures the proper alignment of the first winding mold 105 and the second winding mold 109... The positioning is more convenient and accurate, and the first winding mold 105 and the second winding mold 109 can achieve coaxial self-centering positioning. The second winding mold 109 has multiple third hexagon socket screws 107 threadedly connected to the side of the first winding mold 105. The second winding mold 109 is fixedly connected to the opposite side of the first winding mold 105 by multiple third hexagon socket screws 107. The third hexagon socket screws 107 are used to fix the splicing position between the second winding mold 109 and the first winding mold 105. At the same time, the first winding mold 105 and the second winding mold 109 can be unlocked and separated by removing the third hexagon socket screws 107, which facilitates the separation of the two integrally formed composite materials.

[0024] At least two sealing strips 106 are provided. At least two sealing grooves are provided on the opposite side of the first winding mold 105 and the second winding mold 109 from the inside to the outside. The sealing strips 106 are fixedly embedded in the corresponding sealing grooves. By embedding the sealing strips 106 in the sealing grooves provided on the opposite side of the first winding mold 105 and the second winding mold 109, multiple seals can be achieved between the first winding mold 105 and the second winding mold 109, thereby enhancing the airtightness between the first winding mold 105 and the second winding mold 109 to meet the airtightness requirements.

[0025] Ejection ring 104 is slidably sleeved on the outer wall of the first winding mold 105 and the second winding mold 109 respectively. The ejection ring 104 is provided so that when the composite material is demolded from the first winding mold 105 or the second winding mold 109, the ejection ring 104 moves along the outer wall of the first winding mold 105 or the second winding mold 109, thereby facilitating demolding and improving the demolding efficiency of the composite material.

[0026] A winding shaft 100 is fixedly connected to the middle of the opposite side of the first winding mold 105 and the second winding mold 109. Each of the opposite sides of the first winding mold 105 and the second winding mold 109 is provided with an end plate 110. Multiple second hexagonal socket head cap screws 102 are movably connected to the outer wall of the end plate 110. The two end plates 110 are fixedly connected to the first winding mold 105 and the second winding mold 109 respectively by the second hexagonal socket head cap screws 102. The winding shaft 100 is located near the end plate 110. The end of 10 is movably connected with a first hexagon socket screw 101. The winding shaft 100 is fixedly connected to the end plate 110 at the corresponding position by the first hexagon socket screw 101. The setting of the first hexagon socket screw 101 enables the winding shaft 100 to be detachably installed in the middle of the end plate 110. With the cooperation of the second hexagon socket screw 102, the end plate 110 can be disassembled and installed at the ends of the first winding mold 105 and the second winding mold 109, thereby facilitating the overall assembly and disassembly and improving the convenience of use.

[0027] Among them, an ejector screw 103 is movably connected to the outer side of the end plate 110. One end of the ejector screw 103 is movably connected to the outer wall of the ejector ring 104 at the corresponding position. The setting of the ejector screw 103 can provide auxiliary thrust for the movement of the ejector ring 104 on the outer wall of the first winding mold 105 and the second winding mold 109, thereby improving the convenience of moving the ejector ring 104. Multiple second ejector screws 108 are movably connected to the inner wall of the second winding mold 109 near the first winding mold 105. One end of the second ejector screw 108 penetrates the outer wall of the second winding mold 109 near the first winding mold 105. The setting of the second ejector screw 108 can provide an auxiliary function for the separation between the first winding mold 105 and the second winding mold 109, thereby achieving the function of assisting demolding.

[0028] During assembly, firstly, the first winding mold 105 and the second winding mold 109 are fixed together, using the concave and convex surfaces of their opposite end faces for positioning, and then secured with the third hexagonal socket screw 107. It is important to note that before installing the first winding mold 105 and the second winding mold 109, a sealing strip 106 must be placed in the sealing groove on the end face of the first winding mold 105. Two sealing grooves are provided to ensure airtightness. Then, the second ejector screw 108 is tightened. When the second ejector screw 108 is used for product demolding, it serves to eject the product. Then, the ejector ring 104 is inserted from both ends of the first winding mold body 105 and the second winding mold body 109. The inner diameter of the ejector ring 104 needs to be slightly offset from the first winding mold body 105 and the second winding mold body 109 for easy installation. After the ejector ring 104 is inserted, it does not need to be fixed to the first winding mold body 105 and the second winding mold body 109. When in use, the opposite ends of the first winding mold body 105 and the second winding mold body 109 can be removed.

[0029] Next, install the end plates 110 at both ends of the first winding mold 105 and the second winding mold 109 opposite to each other, and fix them with the second internal hex screws 102. This end face does not need to be positioned and serves as a material stop. Then, install the winding shaft 100 and the ejector screw 103 on the end plate 110, and fix the winding shaft 100 with the first internal hex screw 101. The installation is now complete.

[0030] In practical use, the winding shafts 100 at both ends of the first winding mold 105 and the second winding mold 109 are connected to the winding machine to achieve composite winding molding. After the composite is formed, when demolding is required, since the winding mold designed in this case is a spliced ​​structure of the first winding mold 105 and the second winding mold 109, it can achieve the effect of one out of two. In addition, the shape of the composite product needs to be machined. Before demolding, the outline needs to be machined and a groove is cut in the middle between the first winding mold 105 and the second winding mold 109 to divide the composite into two. Then, the third internal hex screw 107 is unscrewed, and the first winding mold 105 and the second winding mold 109 are separated by the second ejector screw 108. Finally, the ejector screw 103 pushes the ejector ring 104 to eject the composite from the mold, completing the demolding of the composite.

[0031] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
