Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of bulletproof helmet mold technology, and more specifically, to a bulletproof helmet mold that enhances the bulletproof strength of the forehead and chin. Background Technology

[0002] Bulletproof helmet molds typically employ compression molding, modular, or split-type structural designs. They are often made of P20 steel, high-hardness mold steel, or integral steel, and are formed by CNC machining, supplemented by polishing and surface treatment processes. The molds are equipped with heating and cooling circulation pipes, air channels, and other structures. Some modular molds also use elastic supports to achieve synchronous pressurization, and the open design can prevent mold jamming, ensuring the stability and demolding efficiency of the raw materials during high-temperature and high-pressure molding.

[0003] To enhance the bulletproof strength of the front and back of the helmet, existing bulletproof helmets typically use high-strength material to compact the curved parts of the front and back of the helmet. However, the compaction strength of existing bulletproof helmet molds is generally adjusted as a whole, making it difficult to compact only the reinforced areas of the front and back of the helmet individually, which limits their application. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a bulletproof helmet mold that enhances the bulletproof strength of the front and back of the forehead, which solves the technical problem that the compressive strength of bulletproof helmet molds in the prior art is generally adjusted as a whole, making it difficult to compact only the reinforced areas of the front and back of the forehead, resulting in high limitations in its use.

[0005] According to one aspect, at least one embodiment of this disclosure provides a bulletproof helmet mold for enhancing the bulletproof strength of the forehead and chin, comprising a base plate, a mold fixedly connected to the top of the base plate, and further comprising: a compaction plate, an operating port, a support plate, a moving mechanism, and a driving mechanism. Two compaction plates are provided, and grooves are formed on opposite sides of the mold. The two compaction plates are slidably disposed within the two grooves. The operating port is formed on the base plate, and a cavity is formed at the bottom of the mold, communicating with the cavity. Both ends of the support plate are fixedly connected to the inner wall of the cavity. The moving mechanism is disposed on the support plate and is used to support the adjustment of the compaction strength of the two compaction plates. The driving mechanism is disposed at the bottom of the support plate and is used to drive the moving mechanism to move.

[0006] To support the movement and adjustment of the two compaction plates, the moving mechanism includes: a moving frame and a sliding rod. Two moving frames are fixedly connected to each of the two compaction plates. Multiple sliding rods are provided and fixedly connected to the top of the support plate. Each of the multiple moving frames has a sliding hole, and a sliding rod is slidably connected in each sliding hole.

[0007] To drive the two compaction plates to move, the driving mechanism includes: a drive frame, a rotating frame, a bidirectional screw, and a power assembly. Two drive frames are provided, each fixedly connected to one of the two adjacent moving frames. The rotating frame is fixedly connected to the bottom end of the support plate. The bidirectional screw is rotatably connected within the rotating frame. Each drive frame has threaded holes, and the bidirectional screw is threaded into the two threaded holes, which are located on the two ends of the threaded section of the bidirectional screw. The power assembly is located at the bottom end of the support plate and is used to drive the bidirectional screw to rotate.

[0008] To drive the two drive frames to move relative to each other, the power assembly includes: rotating gears, power frames, racks, and a first motor. There are two rotating gears, both of which are fixedly connected to a bidirectional screw. The two rotating gears are located on opposite sides of the rotating frame. There are two power frames, both of which are fixedly connected to the bottom of a support plate. The two ends of the rack are rotatably connected to the two power frames, and the rack meshes with the two rotating gears. The first motor is installed on one side of one of the power frames, and the output end of the first motor passes through the moving frame and is axially fixedly connected to one end of the rack.

[0009] To increase the stability of the sliding rods, a fixing frame is fixedly connected to the top of the support plate, and multiple sliding rods are fixedly connected to the fixing frame.

[0010] To increase the stability of the bidirectional screw during rotation, two fixing blocks are fixedly connected to the inner wall of the cavity, and the two ends of the bidirectional screw are respectively rotatably connected to the two fixing blocks.

[0011] To improve the compaction effect on the bulletproof helmet, the outer surfaces of both compaction plates are aligned with the curvature of the outer surface of the mold.

[0012] To prevent the compaction plate from falling off, a baffle is fixedly connected to the other end of each slide rod.

[0013] The beneficial effects of the embodiments disclosed herein are as follows:

[0014] In this disclosure, a driving mechanism drives a moving mechanism to move, thereby causing two compaction plates to move closer or further apart, thus adjusting the pressure of the two compaction plates on the bulletproof helmet. This allows for individual compaction of only the reinforced areas on the front and back of the forehead, resulting in fewer limitations in its use. Attached Figure Description

[0027] like Figures 1-4As shown, this invention discloses a bulletproof helmet mold for enhancing the bulletproof strength of the front and back foreheads according to one embodiment. The mold includes a base plate 1, with a mold 2 fixedly connected to the top of the base plate 1. It also includes: a compaction plate 3, an operating port 4, a support plate 6, a moving mechanism, and a driving mechanism. The outer surfaces of the two compaction plates 3 have the same curvature as the outer surface of the mold 2. Two compaction plates 3 are provided. Slide grooves are provided on opposite sides of the mold 2, and the two compaction plates 3 are slidably disposed within the two slide grooves. The operating port 4 is located on the base plate 1. A cavity 5 is provided at the bottom of the mold 2, and the operating port 4 communicates with the cavity 5. Both ends of the support plate 6 are fixedly connected to the inner wall of the cavity 5. The moving mechanism is located on the support plate 6 and is used to support the adjustment of the compaction strength of the two compaction plates 3. The driving mechanism is located at the bottom of the support plate 6 and is used to drive the moving mechanism. The driving mechanism drives the moving mechanism to move, thereby causing the two compaction plates 3 to move closer or further apart, thus adjusting the compaction strength of the two compaction plates 3 on the bulletproof helmet. This allows for individual compaction of only the reinforced areas of the front and back foreheads, reducing limitations in application.

[0028] The moving mechanism includes a moving frame 7 and a sliding rod 8. A baffle 18 is fixedly connected to the other end of each sliding rod 8. A fixed frame 16 is fixedly connected to the top of the support plate 6. Multiple sliding rods 8 are fixedly connected to the fixed frame 16. Two moving frames 7 are fixedly connected to each of the two compaction plates 3. Multiple sliding rods 8 are provided and fixedly connected to the top of the support plate 6. Multiple moving frames 7 are provided with sliding holes. A sliding rod 8 is slidably connected in each sliding hole. When the drive frame 9 moves, it drives the moving frame 7 to slide on the sliding rod 8, thereby driving the compaction plate 3 to move and adjust.

[0029] The drive mechanism includes: a drive frame 9, a rotating frame 10, a bidirectional screw 11, and a power assembly. Two fixed blocks 17 are fixedly connected to the inner wall of the cavity 5. The two ends of the bidirectional screw 11 are rotatably connected to the two fixed blocks 17 respectively. There are two drive frames 9, which are fixedly connected to each of two adjacent moving frames 7. The rotating frame 10 is fixedly connected to the bottom end of the support plate 6. The bidirectional screw 11 is rotatably connected inside the rotating frame 10. Each of the two drive frames 9 has a screw hole, and the bidirectional screw 11 is threaded into the two screw holes. The two screw holes are located on the two ends of the threads of the bidirectional screw 11. The power assembly is located at the bottom end of the support plate 6 and is used to drive the bidirectional screw 11 to rotate. The power assembly includes: a rotating gear 12, a power frame 13, a rack 14, and a first motor 15. The rotating gear 12 is... There are two rotating gears 12, both fixedly connected to the bidirectional screw 11. The two rotating gears 12 are located on both sides of the rotating frame 10. There are two power frames 13, both fixedly connected to the bottom of the support plate 6. The two ends of the rack 14 are rotatably connected to the two power frames 13 respectively. The rack 14 meshes with the two rotating gears 12. The first motor 15 is installed on one side of one of the power frames 13. The output end of the first motor 15 passes through the moving frame 7 and is axially fixedly connected to one end of the rack 14. The first motor 15 drives the rack 14 to rotate. When the rack 14 rotates, it drives the two rotating gears 12 to rotate, which in turn drives the bidirectional screw 11 to rotate. When the bidirectional screw 11 rotates, it drives the two drive frames 9 to move away from each other, which in turn drives the moving frame 7 to move on the slide bar 8.

[0030] The working principle is as follows: when it is necessary to adjust the pressure of the compaction plate 3, the first motor 15 is started first. The first motor 15 drives the rack 14 to rotate. When the rack 14 rotates, it drives the two rotating gears 12 to rotate, which in turn drives the double screw 11 to rotate. When the double screw 11 rotates, it drives the two drive frames 9 to move away from each other. When the drive frames 9 move, they drive the moving frame 7 to slide on the slide bar 8, thereby driving the compaction plate 3 to move in the slide groove, thereby adjusting the pressure of the bulletproof helmet.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
