Description

Technical Field

[0001] The utility model belongs to the field of RTM mold production, and in particular relates to a bolt pre-embedded forming positioning component and a multi-bolt pre-embedded forming mold. Background Art

[0002] Resin Transfer Molding (RTM) is a low-cost method for manufacturing composite materials. This process offers advantages such as high efficiency, high-quality parts, high dimensional accuracy, and minimal environmental impact. It is suitable for molding large, complex, and high-strength composite parts. It can also be used to impregnate large components with cores, reinforcements, and embedded parts. It offers a wide range of component types, stable product quality, ease of integration with other fabrication processes, and low-cost manufacturing.

[0003] RTM products are mainly used as covering parts and need to be connected with other parts for use, generally by snap-on connection or bolt connection. Due to product design requirements, the axial direction of the bolts and the demolding direction of the connecting bolts generally have multiple different angles. The traditional bolt method is to embed an iron plate in the reinforcing material parallel to the bolt axis. After forming, holes are punched and tapped on the embedded iron plate according to the positioning points on the mold, and then the screw is installed. In this forming method, since the secondary installation and positioning is performed in the later stage, the accumulation of errors will affect the position of the bolts and fail to meet the accuracy requirements, which cannot meet the assembly needs. In addition, since the bolts are installed by tapping and drilling holes in the embedded iron plate, there are certain requirements for the thickness of the embedded plate. If the iron plate is not thick enough, the screw will easily fall off and the product will leak. However, if the iron plate is too thick, it will affect the external dimensions of the product.

[0049] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention.

[0050] It should be noted that the illustrations provided in this embodiment are only used to schematically illustrate the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0051] RTM products are mainly used as covers to connect with other parts. Due to product design requirements, the bolt axis and the draft direction of the connecting bolts generally have multiple different angles. The traditional bolt method is to embed an iron plate parallel to the bolt axis in the reinforcing material. After forming, holes are punched and tapped on the embedded iron plate according to the positioning points on the mold, and then the screw is installed. This secondary installation and positioning will lead to error accumulation, thereby affecting the position accuracy of the bolt, which cannot meet the assembly requirements well, and has certain requirements for the thickness of the embedded plate.

[0052] See also Figures 1 to 19 The present invention proposes a bolt pre-embedded forming positioning component and a multi-bolt pre-embedded forming mold. The bolt pre-embedded forming positioning component is applied to the multi-bolt pre-embedded forming mold. When the axial direction of multiple embedded bolts 500 is at a different angle from the RTM product demoulding direction, it can also be processed and formed as one piece, solving the problem of secondary production of bolt connections. Specifically, the bolt pre-embedded forming mold includes a mold body and at least one set of positioning components. The mold body includes an upper mold 100 and a lower mold 200 that matches it. The positioning component is arranged between the upper mold 100 and the lower mold 200 and is connected to the upper mold 100. The embedded bolts 500 are positioned and connected to the upper mold 100 by using the positioning component. The product body 600 is layered on the lower mold 200. After the mold is closed, the embedded bolts 500 and the product body 600 are processed and formed as one piece in the mold body, ensuring the accuracy of the position of the embedded bolts 500 and the stability of the connection. The product quality will not be affected during the molding and demoulding process, ensuring the stability of the product quality. The bolts and the product are processed as one piece without the need for secondary connection production, which also improves the processing efficiency.

[0053] See also Figures 1 to 7 According to an embodiment of the present invention, the positioning assembly includes an insert 300 and an embedded bolt seat 400. The insert 300 is connected to the upper mold 100. A first cavity 310 is formed in the insert 300. The first cavity 310 is a conical structure with a small upper size and a large lower size. The shape of the embedded bolt seat 400 matches the shape of the first cavity 310. The embedded bolt seat 400 is disposed in the first cavity 310 and is connected to the insert 300. The embedded bolt hole 410 is formed on the embedded bolt seat 400, and the embedded bolt hole 410 is perpendicular to the bottom surface 430 of the embedded bolt seat. The embedded bolt 500 is connected to the embedded bolt seat 400 through the embedded bolt hole 410. The embedded bolt seat 400 is connected to the upper mold 100 through the insert 300. The embedded bolt seat 400 and the insert 300 are used together to connect and position the embedded bolt 500 to ensure its position accuracy; the embedded bolt reinforcement layer 700 is laid between the embedded bolt 500 and the bottom surface 430 of the embedded bolt seat to enhance the strength of the embedded bolt 500 in the product and improve product quality.

[0054] See also Figures 1 to 7According to an embodiment of the present invention, the insert 300 has magnetism inside to absorb and fix the embedded bolt seat 400. The insert 300 is tightly connected to the embedded bolt seat 400, so that the positioning assembly and the embedded bolt 500 are fixedly connected to the upper mold 100. The cooperation between the insert 300 and the embedded bolt seat 400 ensures a smooth mold closing process, and when the product and the embedded bolt 500 are solidified, the embedded bolt seat 400 and the insert 300 can be easily separated, thereby smoothly demolding and ensuring production efficiency. Specifically, for example, the insert 300 and the embedded bolt seat 400 are made of the same material, and the insert 300 is magnetic inside. The insert 300 can be embedded during the production process of the upper mold 100 to ensure the fixed connection between the upper mold 100 and the insert 300. A magnet is provided on the surface of the first cavity 310 inside the insert 300, and the embedded bolt seat 400 is provided in the first cavity 310. It is adsorbed on the insert 300 under the action of the circumferential magnetic force and thus fits tightly with it.

[0055] Understandably, see Figure 1 Since the upper mold 100 moves in the up and down directions during the mold closing process, the cooperation of the positioning assembly can ensure the stability of the connection between the upper mold 100 and the embedded bolts 500, so that the upper mold 100, the positioning assembly and the embedded bolts 500 can be smoothly closed with the lower mold 200 without affecting the position accuracy of the embedded bolts 500, and the insert 300 and the embedded bolt seat 400 are easy to disassemble, which facilitates the demoulding process.

[0056] Please note that Figure 18 、 Figure 19 , RTM molding obtains an integral body connected by the embedded bolt seat 400, the embedded bolt 500 and the product body 600. After demoulding, the embedded bolt seat 400 is disassembled to obtain a product with the embedded bolt 500; the axial direction of the embedded bolt seat 400 is consistent with the demoulding direction, so the structure of the embedded bolt seat 400 can be used to achieve smooth demoulding without affecting the product body 600 and the embedded bolt 500, thereby ensuring product quality and processing stability.

[0057] See also Figure 12 and Figure 13 According to one embodiment of the present invention, to ensure that the embedded bolt 500 meets the required strength in the finished product, multiple layers of reinforcing material are first applied to the embedded bolt 500 before the embedded bolt 500 is connected to the embedded bolt seat 400. The embedded bolt reinforcement layer 700 is positioned between the embedded bolt 500 and the bottom surface 430 of the embedded bolt seat. After the reinforcing material and resin are cured and formed, the embedded bolt 500 is connected to the product and the bolt's strength is ensured. It should be noted that the embedded bolt 500 should not be tightened too tightly to avoid affecting the flow of resin between the reinforcement layers during the molding process.

[0058] See also Figures 1 to 16 According to one embodiment of the present invention, the embedded bolt seat 400 can be made of, for example, ordinary steel or die steel. It can be milled using a machine tool to create the embedded bolt seat 400 according to the dimensions of the embedded bolt 500, ensuring a precise fit between the insert 300 and the embedded bolt 500. An embedded bolt hole 410 is defined in the center of the embedded bolt seat 400, with the same diameter as the embedded bolt 500. The embedded bolt 500 is threadedly connected to the embedded bolt hole 410, providing a strong and precise fit and ensuring a stable and reliable connection throughout the entire manufacturing process. The thickness of the embedded bolt seat 400 is determined by the length of the embedded bolt 500. Once assembled with the embedded bolt 500, the end of the bolt shank of the embedded bolt 500 is positioned outside the top surface 420 of the embedded bolt seat. For example, the bolt head may protrude slightly by 2-3 mm from the bolt seat, allowing for easy inspection of the tight fit between the embedded bolt 500, the reinforcement layer, and the embedded bolt seat 400, ensuring production quality.

[0059] See also Figures 1 to 16 According to one embodiment of the present invention, at least two disassembly holes 440 are provided on the embedded bolt seat 400, which are distributed around the embedded bolt hole 410 to facilitate disassembly of the embedded bolt seat 400 and the embedded bolt 500. The diameter and position of the disassembly holes 440 are compatible with the wrench 800 used to assist in demolding, and the depth of the disassembly holes 440 does not exceed the thickness of the bolt seat, thereby preventing the resin from solidifying and causing difficulty in disassembly during product processing, which may affect product quality. Specifically, for example, three disassembly holes 440 can be evenly distributed around the embedded bolt hole 410. During disassembly, every two disassembly holes 440 are used in conjunction with the wrench 800. The embedded bolt seat 400 can be disassembled and separated from the embedded bolt 500 by rotating the wrench 800. Of course, in other embodiments, multiple disassembly holes 440 can also be provided on the embedded bolt seat 400 to facilitate disassembly from multiple different angles.

[0060] It is understandable that after the product is demoulded, it is difficult to remove the bolt seat by hand because the embedded bolt seat 400 is connected to the entire product. Using the wrench 800 to assist in demoulding is convenient and labor-saving, which can effectively improve work efficiency.

[0061] See also Figures 1 to 16According to an embodiment of the present invention, the bottom surface 430 of the embedded bolt seat forms an angle with the top surface 420 of the embedded bolt seat. After the embedded bolt 500 is connected to the embedded bolt seat 400, its stud is perpendicular to the bottom surface 430 of the embedded bolt seat, and the axial direction of the embedded bolt seat 400 is consistent with the demoulding direction so that it can be separated from the insert 300 and smoothly demoulded; when the demoulding direction is in the same direction as the direction of the embedded bolt 500, the embedded bolt seat 400 can be, for example, a truncated cone shape, and the axial direction of the embedded bolt hole 410 is consistent with the axial direction of the embedded bolt seat 400; due to different product structures, the demoulding direction and the direction of the embedded bolt 500 may not be in the same direction. The shape of the embedded bolt seat 400 also changes accordingly, forming an angle between the axial direction of the embedded bolt hole 410 and the axial direction of the embedded bolt seat 400. For example, in this case, the top surface 420 of the embedded bolt seat is perpendicular to the axial direction of the embedded bolt seat 400, while the bottom surface 430 of the embedded bolt seat is perpendicular to the axial direction of the embedded bolt hole 410. Therefore, a certain angle is formed between the top surface 420 of the embedded bolt seat and the bottom surface 430 of the embedded bolt seat, roughly forming a cone with the upper and lower bottom surfaces forming an angle, ensuring that it fits well with the embedded bolt 500 and can be smoothly demolded. In other embodiments, the shape of the embedded bolt seat 400 can also be set differently to ensure that it fits well with the embedded bolt 500 and is consistent with the demolding direction.

[0062] See also Figures 1 to 16 According to one embodiment of the present invention, a gap is left between the top surface 420 of the embedded bolt seat and the top surface 320 of the insert to provide space for the installation of the embedded bolt 500. Specifically, for example, after the embedded bolt 500 and the embedded bolt seat 400 are assembled, the bolt head protrudes from the bolt seat by approximately 2-3 mm. A gap of 4-5 mm can be left above the insert 300 to facilitate installation and observation of the connection and fit of the various components, thereby ensuring product processing quality.

[0063] See also Figure 1According to one embodiment of the present invention, the upper mold 100 includes at least one raised structure and at least one set of positioning components. A second cavity 110 is formed within the raised structure for mounting and connecting the positioning components. The positioning components are disposed between the upper mold 100 and the lower mold 200 and are connected to the upper mold 100. Specifically, the positioning assembly includes an insert 300 and an embedded bolt seat 400. The insert 300 is arranged in the second cavity 110 and connected to the upper mold 100. A first cavity 310 is formed in the insert 300. The first cavity 310 is a conical structure with a small upper size and a large lower size; the shape of the embedded bolt seat 400 matches the shape of the first cavity 310. The embedded bolt seat 400 is arranged in the first cavity 310 and connected to the insert 300. An embedded bolt hole 410 is opened on the embedded bolt seat 400, and the embedded bolt hole 410 is perpendicular to the bottom surface 430 of the embedded bolt seat; the embedded bolt 500 is connected to the embedded bolt seat 400 through the embedded bolt hole 410, and the embedded bolt reinforcement layer 700 is laid between the embedded bolt 500 and the bottom surface 430 of the embedded bolt seat. The embedded bolt seat 400 is connected to the upper mold 100 through the insert 300, and the product body 600 is laid on the lower mold 200.

[0064] See also Figures 1 to 17 According to one embodiment of the present invention, a magnetic insert 300 is embedded in the upper mold 100 during the production process. The insert 300 is used in conjunction with the embedded bolt seat 400. The close fit between the insert 300 and the embedded bolt seat 400 enables the connection between the upper mold 100 and the embedded bolt seat 400, thereby positioning the embedded bolt 500. Specifically, the position of the embedded bolt 500 is determined according to the shape and size requirements of the product, thereby determining the position and size of the insert 300. The close fit between the insert 300 and the embedded bolt seat 400, as well as between the embedded bolt seat 400 and the embedded bolt 500, ensures the position accuracy of the embedded bolt 500. In other embodiments, the embedded bolt seat 400 can also be adsorbed onto the insert 300 by using a connection method such as negative pressure to achieve the positioning connection of the embedded bolt 500.

[0065] See also Figures 1 to 17 According to an embodiment of the present invention, a slope 120 is formed around the insert 300 on the side of the upper mold 100 close to the lower mold 200. When the upper mold 100 and the lower mold 200 are closed, the embedded bolt reinforcement layer 700 is laid in the space formed by the slope 120 and the product body 600. The embedded bolt 500 is connected to the product body 600 plane. When the resin is poured, it fills the space and infiltrates the reinforcement material. After curing, the embedded bolt 500 and the product can be molded into one. The structure is simple, the processing is convenient, and the strength of the embedded bolt 500 can be guaranteed.

[0066] See also Figures 1 to 19According to one embodiment of the present invention, the mold includes multiple interconnected parting surfaces that form an angle. The shank of the embedded bolt 500 is perpendicular to the parting surface at the corresponding position of the embedded bolt 500, thereby ensuring the correct positioning of the embedded bolt 500 and the product body 600. It is understood that the product body 600 is horizontally laid on the lower mold 200. According to the product structural design requirements, the embedded bolt 500 is perpendicular to the plane of the product body 600, that is, the shank of the embedded bolt 500 is perpendicular to the parting surface at the corresponding position of the embedded bolt 500. When the product includes multiple embedded bolts 500 at different angles, due to the vertical movement of the upper mold 100 as a whole during the demolding process, the multiple embedded bolts 500 will form multiple different angles with the demolding direction. According to the product structural requirements, different shapes of inserts 300 and embedded bolt seats 400 are used at different positions on the upper mold 100 to achieve good cooperation with the embedded bolts 500, ensure their correct positioning, and ensure the stability of the mold closing and demolding processes.

[0067] See also Figures 1 to 19 Specifically, the axes of the multiple embedded bolt seats 400 are parallel to each other, and the upper mold 100 and the lower mold 200 are demolded and separated along the axial direction of the embedded bolt seats 400. The axial direction of each embedded bolt seat 400 is consistent with the demolding direction, so that the embedded bolt seat 400 and the insert 300 can be accurately matched during the mold closing process and smooth demolding can be ensured. The top surface 420 of the embedded bolt seat is perpendicular to the axial direction of the embedded bolt seat 400, and the bottom surface 430 of the embedded bolt seat is parallel to the parting surface at the corresponding position. According to the product size requirements, the embedded bolt hole 410 is opened at the corresponding position on the embedded bolt seat 400, and the embedded bolt 500 is connected with it and connected to the upper mold 100 through the insert 300 as a whole. The matching between the various components is accurate and the connection is stable, ensuring the accurate position of the embedded bolt 500 after the mold closing. The positioning component has a simple structure and is easy to process, and can effectively ensure the accurate position of the embedded bolt 500 and the stable connection.

[0068] See also Figures 1 to 19First, the thickness of the embedded bolt seat 400 is determined according to the size and position requirements of the embedded bolt 500, and the embedded bolt hole 410 is processed on the embedded bolt seat 400 to connect with the embedded bolt 500. At the same time, multiple disassembly holes 440 are processed around the embedded bolt hole 410 to facilitate subsequent disassembly. The size and shape of the embedded bolt seat 400 vary depending on the angle between the demoulding direction and the embedded bolt 500, and its bottom surface is parallel to or at a certain angle to the top surface; before connecting the embedded bolt 500 to the embedded bolt seat 400, multiple layers of reinforcement material are laid along the axial direction, and then the embedded bolt 500 is matched with the embedded bolt seat 400 for connection. Note that it should not be tightened too tightly to avoid affecting the flow of resin between the reinforcement layers. During the production process of the upper mold 100, an insert 300 is embedded in the corresponding position according to the product structure requirements. The internal dimensions of the insert 300 match the embedded bolt seat 400. The insert 300 is magnetic and can absorb the embedded bolt seat 400 to ensure that the two are tightly matched. Space for the embedded bolt reinforcement layer 700 is reserved at the bottom and around the insert 300. The embedded bolt seat 400 with the reinforcement layer is adsorbed on the insert 300 to achieve the positioning of the embedded bolt 500. At this time, the bottom surface of the embedded bolt 500 is consistent with the plane of the upper mold 100, and the connection is stable.

[0069] The product body 600 is laid on the lower mold 200 in advance. After the embedded bolts 500 are connected to the upper mold 100 through the positioning assembly, the upper mold 100 and the lower mold 200 are clamped. The clamping direction is consistent with the axial direction of the embedded bolt seat 400. The structure and matching connection of the embedded bolt seat 400 and the insert 300 are used to ensure smooth clamping, and the position of the embedded bolt 500 is stable during the clamping process. After clamping, the embedded bolt 500 is connected to the upper plane of the product body 600 to ensure that the relative position is accurate and the verticality is good. After pressure holding, infusion and curing, demoulding is carried out. The separation of the embedded bolt seat 400 and the insert 300 is used to achieve demoulding, ensuring that the product and the embedded bolt 500 will not be affected during the demoulding process. After demoulding, an RTM molded product connected as one with the embedded bolt seat 400 is obtained.
