Description

Technical Field

[0001] This utility model relates to the field of carbon fiber safety helmet processing, and in particular to an integrated molding device for carbon fiber safety helmet processing. Background Technology

[0002] In the fields of industrial production and safety protection, safety helmets are crucial equipment for ensuring the safety of workers' heads, and their performance and quality are of paramount importance. With the continuous development of materials science, carbon fiber, with its many excellent properties such as high strength, high modulus, low density, and corrosion resistance, has gradually become an ideal material for manufacturing high-performance safety helmets.

[0003] For example, a carbon fiber safety helmet one-piece molding device with publication (announcement) number CN118024617A includes a molding upper mold set directly above the molding lower mold, a molding upper module fixed to the bottom of the molding upper mold by a support sleeve, and a hydraulic push rod fixed to the top of the molding upper mold. The molding upper module has a feeding port for adding carbon fiber, the molding lower mold has a channel for conveying raw materials, and the molding lower mold has a groove. Above the molding lower mold are a clearing component for unblocking the channel and a dispersing component for evenly distributing carbon fiber in various areas of the safety helmet, which can effectively prevent carbon fiber from blocking the feeding port. However, since the carbon fiber safety helmet is easy to stick to the mold after molding, the device cannot automatically eject the carbon fiber safety helmet from the mold, and manual demolding is required afterward, which is inefficient and inconvenient.

[0004] Therefore, it is necessary to design an integrated molding device for carbon fiber safety helmet processing that can automatically eject and demold carbon fiber safety helmets without the need for manual demolding afterwards, thereby improving work efficiency. Utility Model Content

[0005] To overcome the shortcomings of existing devices that cannot automatically eject and demold carbon fiber safety helmets after molding, requiring manual demolding and resulting in low efficiency, this utility model provides an integrated molding device for carbon fiber safety helmet processing that can automatically eject and demold carbon fiber safety helmets without requiring manual demolding, thereby improving work efficiency.

[0006] The technical solution is as follows: An integrated molding device for processing carbon fiber safety helmets includes a support frame, guide rods, a two-way lead screw, gears, molds, a pressing component, and a demolding component. The front of the support frame is connected to two guide rods, and the lower rear of the support frame is also connected to a guide rod. The rear of the support frame is rotatably connected to a two-way lead screw, and a gear is connected to the middle of the two-way lead screw. The left and right sides of the two-way lead screw are threadedly connected to the molds. The guide rods are slidably connected to the molds. The upper part of the support frame is provided with a pressing component capable of extrusion molding, and the support frame is provided with a demolding component capable of automatically ejecting and demolding the carbon fiber safety helmet.

[0007] As a further preferred embodiment, the pressing assembly includes a hydraulic cylinder, a mounting bracket, a hot pressing block, and a rack. The hydraulic cylinder is connected to the upper part of the support bracket. The hydraulic cylinder and the processor are electrically connected through a control module. The mounting bracket is connected to the telescopic end of the hydraulic cylinder. The hot pressing block is connected to the lower side of the mounting bracket. The rack is connected to the rear side of the mounting bracket. The rack meshes with the gear.

[0008] As a further preferred embodiment, a demolding assembly is also included. The demolding assembly includes an extrusion block, an ejector frame, a first telescopic spring, a slide rod, a second telescopic spring, a push rod, and a third telescopic spring. Extrusion blocks are connected to the inner sides of both the left and right sides of the support frame. Ejector frames are slidably connected to both parts of the mold. Each ejector frame is connected to an adjacent mold with a first telescopic spring. A slide rod is slidably connected to the outer part of each ejector frame. A second telescopic spring is connected to each slide rod. Push rods are slidably connected to both the front and rear parts of the mold. Each push rod passes through an adjacent ejector frame. A third telescopic spring is connected to each push rod and an adjacent mold. Both the push rod and the slide rod are in contact with the adjacent extrusion block.

[0009] As a further preferred option, the extrusion block has a convex structure.

[0010] As a further preferred option, the parts of the ejector frame that are close to each other are all arc-shaped structures.

[0011] As a further preferred option, the second telescopic spring has a larger spring force coefficient than the first telescopic spring.

[0012] This invention has the following advantages: By separating the molds, the extrusion block contacts the extrusion slide bar, which first drives the ejector frame to move inward. When the ejector frame moves to its limit, the slide bar moves on the ejector frame. At the same time, the extrusion block extrudes the ejector rod, causing the ejector rod to eject the carbon fiber safety helmet again. This achieves automatic ejection and demolding of the carbon fiber safety helmet, eliminating the need for manual demolding and improving work efficiency. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0019] An integrated molding device for processing carbon fiber safety helmets, such as Figure 1 and Figure 2 As shown, it includes a support frame 1, guide rods 2, a double-acting screw 3, a gear 4, a mold 5, a pressing assembly, and a demolding assembly. The front of the support frame 1 is connected to two guide rods 2, and the lower rear of the support frame 1 is also connected to a guide rod 2. The rear of the support frame 1 is rotatably connected to the double-acting screw 3, and the middle of the double-acting screw 3 is connected to the gear 4. The left and right sides of the double-acting screw 3 are threadedly connected to the mold 5. The guide rods 2 are slidably connected to the mold 5. The upper part of the support frame 1 is provided with a pressing assembly, and the support frame 1 is provided with a demolding assembly.

[0020] like Figure 1 and Figure 2 As shown, the pressing assembly includes a hydraulic cylinder 6, a mounting bracket 7, a hot pressing block 8, and a rack 9. The upper part of the support frame 1 is connected to the hydraulic cylinder 6. The hydraulic cylinder 6 and the processor are electrically connected through a control module. The mounting bracket 7 is connected to the telescopic end of the hydraulic cylinder 6. The hot pressing block 8 is connected to the lower side of the mounting bracket 7. The rack 9 is connected to the rear side of the mounting bracket 7. The rack 9 meshes with the gear 4.

[0021] like Figures 1-4As shown, it also includes a demolding assembly, which includes an extrusion block 10, an ejector frame 11, a first telescopic spring 12, a slide bar 13, a second telescopic spring 14, an ejector rod 15, and a third telescopic spring 16. Extrusion blocks 10 are connected to the inner sides of both the left and right sides of the support frame 1. The extrusion blocks 10 have a convex structure for easy extrusion. Ejector frames 11 are slidably connected to each mold 5. The parts of the ejector frames 11 that are close to each other have an arc-shaped structure. Each ejector frame 11 is connected to the adjacent mold 5 by a first telescopic spring. The ejector frame 11 and the spring 12 are slidably connected to each other by a slide rod 13. The slide rod 13 is connected to the ejector frame 11 by a second extension spring 14. The second extension spring 14 has a larger elastic coefficient than the first extension spring 12. The front and rear parts of the mold 5 are slidably connected by a push rod 15. The push rod 15 passes through the adjacent ejector frame 11. The push rod 15 is connected to the adjacent mold 5 by a third extension spring 16. The push rod 15 and the slide rod 13 are in contact with the adjacent extrusion block 10.

[0022] At this time, the first telescopic spring 12, the second telescopic spring 14, and the third telescopic spring 16 are all in the retracted state. When using this device, first place the support frame 1 in the carbon fiber safety helmet processing area, then place the carbon fiber safety helmet material between the molds 5. Then, the processor starts the hydraulic cylinder 6 through the control module, which drives the mounting frame 7 and the hot pressing block 8 to move downward. During the movement, the gear 4 and the rack 9 mesh with each other, which drives the bidirectional lead screw 3 to rotate, so that the mold 5 moves under the action of the thread, so that the molds 5 move closer to each other, which drives the push rod 15 and the slide rod 13 to move, so that the push rod 15 and the slide rod 13 no longer contact the extrusion block 10. The first telescopic spring 12, the second telescopic spring 14, and the third telescopic spring 16 return to their original positions, which drives the ejector frame 11, the slide rod 13, and the push rod 15 to move to the right and retract, and perform hot pressing molding through the mold 5.

[0023] After the carbon fiber safety helmet is formed, the hydraulic cylinder 6 drives the mounting frame 7 and the hot pressing block 8 to move upward. The gear 4 and the rack 9 mesh with each other, driving the bidirectional lead screw 3 to rotate. This causes the mold 5 to move under the action of the thread, making the molds move away from each other. This allows the extrusion block 10 to contact the extrusion slide rod 13. The second telescopic spring 14 has a larger elastic coefficient than the first telescopic spring 12, so it will first drive the ejector frame 11 to move inward. The first telescopic spring 12 is compressed and contracted, so that the carbon fiber safety helmet is no longer in contact with the mold 5. When the ejector frame 11 moves to its limit, the slide rod 13 will move on the ejector frame 11. The second telescopic spring 14 is compressed and contracted. At the same time, the extrusion block 10 presses the ejector rod 15, causing the ejector rod 15 to move inward. The third telescopic spring 16 is compressed and contracted, so that the ejector rod 15 ejects the carbon fiber safety helmet again. This allows for automatic ejection and demolding of the carbon fiber safety helmet, eliminating the need for manual demolding and improving work efficiency.
