[0001] This utility model relates to the field of carbon fiber processing mold technology, and more specifically, to an in-mold curing mold for carbon fiber irregular components. Background Technology

[0002] Carbon fiber composites are high-performance composite materials composed of carbon fibers, resins, and other materials. Carbon fibers possess excellent properties such as high strength, high modulus, and lightweight, making them an ideal reinforcing material for manufacturing high-performance carbon fiber composite parts. Carbon fiber hot pressing molds are molds used to shape carbon fiber materials under high temperature and pressure conditions. These molds are mainly used for the compression molding of carbon fiber composites and are suitable for industries such as automotive, aerospace, and electronics. Carbon fiber hot pressing molds are core equipment for the molding and processing of irregularly shaped carbon fiber components.

[0003] However, due to the diverse shapes and standards of carbon fiber irregular components, mold replacement is required when processing irregular components of different shapes. The current mold replacement method generally requires disassembling and installing the mold within the working range of the equipment. This method has operational risks and limited operating space. At the same time, when the mold is operating under high pressure, it will put great pressure on the bottom mounting structure, which will reduce the life of the bottom mounting structure. Utility Model Content

The lower mold is mounted on the base. The guide pillars are fixedly mounted on the base and provide fixed support for the upper frame. The hydraulic cylinder is fixedly mounted on the upper frame and vertically drives the movable frame to move vertically along the guide pillars. The upper mold is mounted on the movable frame. Two side positioning mechanisms are mounted on the movable frame, which fix the upper mold to the movable frame. The base has a side sliding groove, and a mounting seat is slidably mounted inside the side sliding groove. A horizontal cylinder for driving the mounting seat to translate along the inside of the side sliding groove is fixedly mounted on the base. Connecting blocks are slidably connected to both sides of the lower mold. The connecting blocks are detachably fixed to the mounting seat by bolts. A movable support member for supporting the lower mold is mounted on the mounting seat. The movable support member transmits the vertical pressure on the lower mold downward to the base. A controller for signal coordination and control of the hydraulic cylinder and the horizontal cylinder is mounted on the base.

[0007] As a further description of the above technical solution: the movable support includes uniformly distributed elastic elements and a support plate. The elastic elements are movably installed on the mounting base, the top of the elastic elements is connected and fixed to the support plate, and the top of the support plate is in contact with the lower mold.

[0008] As a further description of the above technical solution: the elastic component includes a slide rod and a damping spring. The outer side of the slide rod is slidably connected to the mounting base. The damping spring is sleeved on the outer side of the slide rod. The top end of the damping spring is fixedly connected to the support plate. The bottom end of the damping spring is fixedly connected to the mounting base. The top end of the slide rod is fixedly connected to the support plate. The slide rod moves downward under vertical pressure, passes through the mounting base, and contacts the base.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] This solution uses movable support components and connecting blocks to connect the lower mold to the mounting base. Simultaneously, it provides vertical movable support for the lower mold, ensuring that pressure is directly transmitted to the base when under stress, reducing pressure loss on the mounting base and extending equipment lifespan. Furthermore, it utilizes a side pressure mechanism in conjunction with a horizontal cylinder to move the mounting base, enabling flexible mold disassembly.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0021] Please see Figure 1-4 In this utility model, an in-mold curing mold for carbon fiber irregular components includes a base 1, guide pillars 2, an upper frame 3, a hydraulic cylinder 4, a movable frame 5, an upper mold 6, and a lower mold 15. The lower mold 15 is installed on the base 1. The guide pillars 2 are fixedly installed on the base 1 and provide fixed support for the upper frame 3. The hydraulic cylinder 4 is fixedly installed on the upper frame 3 and vertically drives the movable frame 5 to move vertically along the guide pillars 2. The upper mold 6 is installed on the movable frame 5. Two side positioning mechanisms 7 are installed on the movable frame 5, and the two side positioning mechanisms 7 fix the upper mold 6 on the movable frame 5. The base 1 is provided with The side slide groove 8 has a mounting base 9 slidably installed inside it. A horizontal cylinder 10 for driving the mounting base 9 to translate along the inside of the side slide groove 8 is fixedly installed on the base 1. Connecting blocks 11 are slidably connected to both sides of the lower mold 15. The connecting blocks 11 are detachably fixed to the mounting base 9 by bolts. A movable support member 12 for supporting the lower mold 15 is installed on the mounting base 9. The movable support member 12 transmits the vertical pressure on the lower mold 15 downward to the base 1. A controller 13 for signal coordination control of the hydraulic cylinder 4 and the horizontal cylinder 10 is installed on the base 1.

[0022] In this invention, the base 1 supports the guide column 2. The controller 13 activates the hydraulic cylinder 4 to lower the movable frame 5, thereby lowering the upper mold 6 and placing the carbon fiber composite substrate into the lower mold 15. As the upper mold 6 descends, the high temperature and pressure are used to shape the carbon fiber composite substrate, thus forming the carbon fiber component. During the hot pressing process, the lower mold 15 is compressed and slides down along the connecting block 11, pressing the movable support 12 so that it descends along the mounting base 9 and contacts the bottom base 1 to reduce the pressure on the mounting base 9. When the mold needs to be changed, the hydraulic cylinder 4 is activated to lower the upper mold 6 until it fits with the lower mold 15. Then, the two side positioning mechanisms 7 are activated to move laterally and release the positioning of the upper mold 6. At this time, the upper mold 6 separates from the movable frame 5 and is stably placed on the lower mold 15. Then, the horizontal cylinder 10 is activated to move the bottom mounting base 9 to the right along the side slide groove 8, so that it leaves the equipment working space. Then, the connection block 11 and the mounting base 9 are closed. The bolts are removed, and the upper mold 6 and lower mold 15 are lifted and moved using a lifting device to complete the disassembly. Then, the new mold is installed by using the lifting device to align the lower mold 15 with the mounting base 9, and the upper mold 6 is fitted onto the lower mold 15. Then, the horizontal cylinder 10 is activated to push the mounting base 9 back to its original position. Then, the hydraulic cylinder 4 is activated to drive the movable frame 5 to descend and align it with the upper mold 6. The side positioning mechanism 7 is then restarted to engage the two sides of the upper mold 6 and fix it on the movable frame 5, thus achieving reinstallation. This device has the advantages of convenient and safe replacement operation, and reduces the pressure on the bottom mounting structure during hot pressing, thereby improving its service life. It solves the problem of existing mold replacement methods, which generally require mold disassembly and installation within the working range of the equipment. This method has operational risks and limited operating space. At the same time, the mold will put great pressure on the bottom mounting structure when operating under high pressure, which will reduce the service life of the bottom mounting structure.

[0023] Please see Figure 2 The movable support 12 includes evenly distributed elastic members 121 and support plates 122. The elastic members 121 are movably installed on the mounting base 9. The top of the elastic members 121 is connected and fixed to the support plates 122. The top of the support plates 122 is in contact with the lower mold 15.

[0024] In this utility model, the elastic member 121 provides elastic support to the support plate 122, and the support plate 122 provides contact support to the lower mold 15. When the lower mold 15 is subjected to the working pressure of the upper mold 6, it pushes the support plate 122 downward to squeeze the elastic member 121, and makes the bottom of the elastic member 121 contact the bottom base 1 to realize pressure transmission, reduce the pressure on the mounting seat 9, and protect the bottom support structure.

[0025] Please see Figure 2The elastic element 121 includes a slide rod 1211 and a damping spring 1212. The outer side of the slide rod 1211 is slidably connected to the mounting base 9. The damping spring 1212 is sleeved on the outer side of the slide rod 1211. The top end of the damping spring 1212 is fixedly connected to the support plate 122. The bottom end of the damping spring 1212 is fixedly connected to the mounting base 9. The top end of the slide rod 1211 is fixedly connected to the support plate 122. The slide rod 1211 moves downward under vertical pressure, passes through the mounting base 9, and contacts the base 1.

[0026] In this invention, the sliding rod 1211, in conjunction with the damping spring 1212, can provide static support for the lower mold 15, allowing the mounting base 9 to still move horizontally after being connected to the lower mold 15. Furthermore, when subjected to downward pressure, the damping spring 1212 is compressed, causing the sliding rod 1211 to move downward and contact the base 1, thereby transmitting the pressure to the base 1 and reducing pressure loss on the mounting base 9.

[0027] Please see Figure 1 The side positioning mechanism 7 includes a drive cylinder 71 and a locking block 72. The drive cylinder 71 is fixedly installed at the bottom of the movable frame 5. The movable end of the drive cylinder 71 is fixedly connected to the locking block 72. One side of the locking block 72 is locked to the side of the upper mold 6.

[0028] In this utility model, the drive cylinder 71 is activated to drive the locking block 72 to move and contact the side of the upper mold 6, thereby stably connecting the upper mold 6 with the movable frame 5 and facilitating disassembly.

[0029] Please see Figure 3 and Figure 4 The upper mold 6 has pressure sensors 61 fixedly connected to both sides of the bottom, and a docking post 611 fixedly connected to the bottom of the pressure sensor 61. The lower mold 15 has a docking groove 151 that mates with the docking post 611.

[0030] In this invention, the docking accuracy between the upper mold 6 and the lower mold 15 is detected by the docking column 611 and the docking groove 151. When the docking accuracy of the two is deviated, the pressure sensor 61 detects the extrusion force on the docking column 611 in real time. When the pressure detected by the pressure sensor 61 exceeds the set threshold, the signal is sent to the controller 13, and the controller 13 controls the hydraulic cylinder 4 to stop pressing down and reset to avoid damaging the mold.

[0031] Please see Figure 1 The upper mold 6 and the lower mold 15 are both provided with internal channels 14 for connecting to external heat sources.

[0032] In this invention, the inner channel 14 facilitates connection to an external heat source, enabling the provision of high temperature during hot pressing and achieving high-temperature and high-pressure molding conditions.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
