Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of safety helmet production, in particular to a composite material safety helmet forming die. Background Art
[0002] A forming mold, also called a molding die, is a mold made in proportion to the shape and structure of an object. It is used to shape materials by pressing or pouring. It is commonly used in plastic processing. A hard hat is a headgear designed to protect the head from falling objects and other specific factors. A hard hat consists of a shell, lining, chin strap, and accessories. Mold processing is a common method for manufacturing hard hats.
[0003] Related technology (publication number: CN217226528U) discloses a helmet forming mold with a rapid curing structure, and the disclosed technical solution is as follows: through the arrangement of a closing component, a closing sleeve, an air outlet, a circular groove, a telescopic spring, a closing block, a sealing ring, a demoulding component, an electric lifting sleeve rod, a lifting block, an air pump, a top block and an air groove, the purpose of quickly demoulding the mold can be achieved. After the mold is injection molded, the power supply of the electric lifting sleeve rod is turned on to push the lifting block and the air pump to move the top block upward, so that the closing block and the sealing ring squeeze the telescopic spring and leak out of the air outlet and the air groove. Then, the power supply of the air pump is turned on to make the gas ejected from the air outlet and the air groove, and the mold is demoulded, and the interior is expanded so that the mold can be easily demoulded. Then, the electric lifting sleeve rod is lowered, and the telescopic spring inside the circular groove performs a reset movement to eject the closing block and make the next mold, thereby avoiding adhesion of the mold during demoulding, resulting in a decrease in the mold yield rate, and increasing the yield rate of the device.
[0004] In the above-mentioned disclosed technical solutions, the following problems were found in the related technologies: when the safety helmet is demolded from the mold after processing, the filling metal liquid repeatedly impacts the mold under high pressure and high speed, causing a chemical reaction between the mold steel surface and the casting alloy, forming a chemical reaction layer on the mold surface, thereby causing the casting to stick to the mold, which not only affects the surface quality and dimensional accuracy of the casting, but may also increase the mold repair time and cost. Since the temperature is high during mold processing, the formed safety helmet is easily attached to the mold cavity, which makes the safety helmet difficult to remove and dangerous during the removal process. In the process of using some cooling methods, the safety helmet needs to be operated in the mold cavity, resulting in a long mold cavity occupancy time, which in turn affects the production efficiency of the safety helmet. In this regard, we have proposed a new composite material safety helmet forming mold.
[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background technology section of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the composite material helmet forming mold:
[0016] 1. Through the forming driving component, the die is moved horizontally toward the punch, and then injection is performed inside through the injection hole on the die. After the safety film is formed, the die is moved in the opposite direction through the forming driving component, thereby completing the processing of the safety helmet and making the operation process more convenient.
[0017] Second, during demoulding, the demoulding movable part is adjusted to an active state through the movable-fixed switching assembly, and the die is driven to move away from the punch through the forming driving component, so that the demoulding fixed part pushes the demoulding movable part to move in the through hole of the die, so that the demoulding movable part drives the formed safety helmet to be pushed out of the die cavity of the die, thereby taking out the formed safety film, and then continuing the helmet molding process, making the operation of the helmet molding process more convenient and improving the efficiency of safety helmet production.

DETAILED DESCRIPTION
[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0031] The following is a combination of specific implementation cases and attached Figure 1-6 The present invention will be further described below, but the present invention is not limited to these embodiments.
[0032] A composite material helmet forming mold includes a mold frame 1, the inner side wall of the mold frame 1 is provided with a punch 2, and the right inner wall of the mold frame 1 is fixedly mounted with the punch 2 for forming the helmet, and the punch 2 is in the shape of the helmet. The inner cavity of the mold frame 1 is provided with a die 3 corresponding to the punch 2, and the side opposite to the punch 2 is provided with a die 3 that moves laterally in the inner cavity of the mold frame 1, and a mold cavity 10 corresponding to the punch 2 is provided on the surface of the die 3 opposite to the punch 2. An exhaust hole 26 connected to the mold cavity 10 is provided at the top of the die 3. When the helmet is molded, exhaust is discharged through the exhaust hole 26.
[0033] The inner cavity of mold frame 1 is equipped with a molding drive component that drives the female mold 3 to close. The molding drive component causes the female mold 3 to move laterally toward the male mold 2. Since the shapes of the male mold 2 and female mold 3 correspond, the molding drive component allows the female mold 3 to fit the male mold 2. The mold is then injected into the female mold 3 through the injection hole in the female mold 3. After the safety film is formed, the molding drive component causes the female mold 3 to move in the opposite direction, completing the production process of the helmet. This makes the operation more convenient.
[0034] A demoulding fixed member 4 is provided on the inner wall of the mold frame 1 opposite to the groove 3, and a demoulding movable member 5 is provided on the side wall of the die 3 away from the punch 2, and the demoulding movable member 5 corresponds to the demoulding fixed member 4. One end of a support column 17 is vertically fixedly installed on the right inner wall of the mold frame 1, and the demoulding fixed member 4 is fixedly installed on the other end of the support column 17. A through hole is provided on the side surface of the die 3 opposite to the demoulding fixed member 4, which passes through the inner cavity. The shape of the demoulding movable member 5 corresponds to the aperture of the through hole, so that the demoulding movable member 5 extends to the inner cavity of the die 3 after passing through the through hole. The surface shape of the demoulding movable member 5 extending to the inner cavity of the die 3 corresponds to the shape of the inner wall of the mold cavity 10, so that after the demoulding movable member 5 extends into the groove 3, the demoulding movable member 5 and the inner wall of the mold cavity 10 form a complete mold cavity, and the overall shape of the mold cavity 10 corresponds to the punch 2.
[0035] The sidewall of the die 3 is equipped with a switching assembly for switching the state of the ejector 5. When driving the die 3 and punch 2 for the mold closing process, the switching assembly first aligns the ejector 5 with the inner wall of the mold cavity 10 and then locks it. The forming drive assembly then drives the die 3 toward the punch 2, thereby forming the helmet.
[0036] When the helmet is subsequently demolded, the demolding movable member 5 is adjusted to an active state through the movable-fixed switching assembly. The die 3 is then driven by the molding drive member to move away from the punch 2. When the die 3 drives the demolding movable member 5 to a position in contact with the demolding fixed member 4, as the die 3 continues to move, the demolding fixed member 4 pushes the demolding movable member 5 to move within the through hole of the die 3, so that the demolding movable member 5 drives the molded helmet out of the mold cavity 10 of the die 3, thereby removing the molded safety film.
[0037] After that, the helmet molding process is continued, making the operation of the helmet molding process more convenient and improving the efficiency of helmet production. In the demoulding process, the demoulding is pushed by the demoulding fixed member 4 and the demoulding movable member 5 to avoid contact with the helmet, thereby improving the safety of the processing process.
[0038] The movable / fixed switching assembly includes a switching shaft 19 rotatably mounted on the surface of the die 3 facing away from the punch 2. A bearing is embedded in the surface of the die 3 near the stripper 4. One end of the switching shaft 19 is embedded within the bearing, so that the two switching shafts 19 are symmetrically located on either side of the stripper 5. A support plate 20 is mounted on the surface of the stripper 5 facing the stripper 4. The support plate 20 is securely fixed to the surface of the stripper 5.
[0039] The switch shaft 19 extends through the inner cavity of the support plate 20 and outward. Positioning clips 8 are symmetrically arranged on the outer wall of the switch shaft 19, with two sets of positioning clips 8 placed on either side of the through-hole between the switch shaft 19 and the support plate 20. Positioning clips 8 are fixedly mounted on both the upper and lower sides of the outer wall of the switch shaft 19, with both positioning clips 8 aligned vertically. The four positioning clips 8 are divided into two groups, each attached to either side of the through-hole between the switch shaft 19 and the support plate 20. The positioning clips 8 are attached to the surface of the support plate 20.
[0040] The inner walls of the through-holes of the switching shaft 19 and the support plate 20 are symmetrically provided with through-slots 9 corresponding to the positioning clips 8. Two through-slots 9 are transversely defined on the inner walls of the through-holes of the switching shaft 19 and the support plate 20. The shape of the through-slots 9 corresponds to the shape of the positioning clips 8, allowing the positioning clips 8 to pass through the through-slots 9. A rotary drive assembly that drives the switching shaft 19 is provided on the side wall of the die 3 facing the support plate 20. The rotation of the switching shaft 19 is caused by the drive assembly.
[0041] When driving the die 3 and the punch 2 to close the mold, the switching shaft 19 is rotated by rotating the driving assembly, so that the switching shaft 19 drives the two sets of positioning clamps 8 on the outer wall to rotate, so that the two sets of positioning clamps 8 are respectively rotated to a position perpendicular to the through groove 9. At this time, the support plate 20 is located between the two sets of positioning clamps 8, so that the demoulding movable member 5 is in a locked position, and then the die 3 is driven to move, ensuring that the mold cavity 10 of the die 3 is in a completely closed position.
[0042] After the helmet processing is completed, the switching shaft 19 is again rotated by the drive assembly to drive the positioning clamps 8 on both sides to rotate to a position opposite to the through slot 9. As the die 3 moves during the demoulding process, the die 3 drives the demoulding movable member 5 to move, so that the demoulding movable member 5 drives the support plate 20 to engage with the surface of the demoulding fixed member 4. As the demoulding movable member 5 moves, the demoulding fixed member 4 pushes the demoulding movable member 5 into the mold cavity 10 through the support plate 20. This makes the helmet formed inside being removed, making the operation process more convenient and switching according to the processing process, thereby improving the efficiency of the helmet processing process.
[0043] It is worth noting that the rotary drive assembly includes a first gear 24 that is rotatably arranged on the surface of the side of the die 3 away from the punch 2, and a second gear 23 is sleeved on the outer wall of the switching shaft 19, and the second gear 23 is meshed with the first gear 24. The specifications of the first gear 24 are smaller than those of the second gear 23, that is, the small gear drives the large gear to rotate. The first motor 25 is fixed by the first hood 27 on the surface of the die 3 relative to the support plate 20. The output shaft of the first motor 25 passes through the side wall of the first hood 27 and extends to the outside. The first motor 25 is electrically connected to the external power supply via a wire. The first gear 24 is fixedly sleeved on the outer wall of the output shaft of the first motor 25 through a mounting hole opened in the center, and the second gear 23 is fixedly sleeved on the outer wall of the switching shaft 19 through a mounting hole opened in the center.
[0044] During the mold closing and demolding process, the output shaft of the first motor 25 drives the first gear 24 to rotate, so that the second gear 23 engaged with the first gear 24 drives the switching shaft 19 to rotate, thereby bringing convenience to the operation process of relevant personnel.
[0045] In addition, one end of the switching shaft 19 passes through the outside of the support plate 20 and is rotatably mounted on a support seat 29 on the side wall of the support plate 20. The support seat 29 is fixed to the surface of the support plate 20 by three circumferential rods. A bearing is embedded in the surface of the support seat 29. The end of the switching shaft 19 extending from the rear of the support plate 20 toward the inner wall of the mold frame 1 is embedded in the bearing. The support of the switching shaft 19 at two points, the support seat 29 and the surface of the die 3, ensure the stability of the switching shaft 19 during rotation.
[0046] In addition, an elastic reset member 22 is provided between the support plate 20 and the die 3. The elastic reset member 22 can be a compression spring, and the two ends of the elastic reset member 22 are respectively fixed on the opposite surfaces of the support plate 20 and the die 3.
[0047] As the mold 3 drives the demoulding movable member 5 toward the demoulding fixed member 4 via the molding drive component, the elastic return member 22 is compressed and generates elastic force as the demoulding movable member 5 moves within the through-hole of the mold 3. When the helmet is demoulded, the elastic force of the elastic return member 22 moves the demoulding movable member 5 back to its original position, thus avoiding positional deviation and ensuring the quality of helmet production.
[0048] Furthermore, the molding drive assembly includes a lead screw 7 rotatably disposed within the interior of the mold frame 1. A mold displacement member 11 is threadedly connected to the outer wall of the lead screw 7, and the mold displacement member 11 is fixedly mounted on the side wall of the die 3. Bearings are embedded in the inner walls of both sides of the mold frame 1, and the ends of the lead screw 7 are embedded in the interior of the two bearings. A second motor 18 is secured to the outer wall of the mold frame 1 via a second hood 16, and the second motor 18 is electrically connected to an external power source via a wire. The output shaft of the second motor 18 passes through the side walls of the second hood 16 and the side walls of the mold frame 1, extending into the interior and fixedly connected to the corresponding end of the lead screw 7.
[0049] When the safety helmet is being molded and demolded, the second motor 18 is connected to a power source so that the output shaft of the second motor 18 drives the screw 7 to rotate, and the mold displacement part 11 threadedly connected to the outer wall of the screw 7 drives the die 3 to move, thereby bringing convenience to the processing process of relevant personnel.
[0050] The inner cavity of the mold frame 1 is embedded with a guide rod 15 parallel to the lead screw 7. The outer wall of the guide rod 15 is sleeved with an anti-deflection seat 14, which is fixedly mounted on the side wall of the die 3. The two ends of the guide rod 15 are respectively perpendicularly fixed to the inner walls of the mold frame 1 on both sides. The anti-deflection seat 14 is movably sleeved on the outside of the guide rod 15 through a through hole opened on the surface and penetrating the inner cavity.
[0051] In the process of rotating the screw 7 to adjust the position of the die 3, the die 3 simultaneously drives the anti-deflection seat 14 to slide against the outer wall of the guide rod 15. The guide rod 15 parallel to the screw 7 ensures the stability of the die 3 during the mold closing and demolding process, avoids position deviation, thereby ensuring the sealing of the die 3 and the punch 2, and further ensuring the quality of the safety helmet.
[0052] A material receiving box 6 is provided below the die 3, and the material receiving box 6 is arranged in the inner cavity of the mold frame 1 through a disassembly assembly. The disassembly assembly allows the material receiving box 6 to be installed and removed. By placing the material receiving box 6 below the die 3, the process of collecting the helmets after molding is more convenient.
[0053] The assembly and disassembly assembly consists of base frames 13 embedded in the inner walls of the mold frame 1. These base frames 13 are connected to the material receiving box 6 via right-angle fixtures 12. The two base frames 13 are vertically fixed to the inner walls of the mold frame 1. The two sides of the right-angle fixtures 12 are then attached to the base frames 13 and the surface of the material receiving box 6. Bolts are then passed through the right-angle fixtures 12 and secured to the surface of the material receiving box 6. The bolts allow for installation and removal of the right-angle fixtures 12, making handling and installation of the material receiving box 6 more convenient.
[0054] This embodiment of a composite helmet molding mold operates as follows: During mold closing, the output shaft of a first motor 25 first drives the first gear 24 to rotate. This in turn causes the second gear 23, meshing with the first gear 24, to rotate the switching shaft 19, which in turn drives the two sets of positioning clips 8 on the outer wall to rotate until the two sets of positioning clips 8 are perpendicular to the through slot 9. At this point, the two sets of positioning clips 8 center the support plate 20, locking the demolding member 5 in place.
[0055] Then, the second motor 18 is connected to a power source so that the output shaft of the second motor 18 drives the lead screw 7 to rotate, so that the mold displacement member 11 threadedly connected to the outer wall of the lead screw 7 drives the die 3 to move, and moves the die 3 to a position that fits the punch 2.
[0056] After the helmet is molded, the first gear 24 is driven to rotate by the output shaft of the first motor 25. The second gear 23 meshing with the first gear 24 drives the switching shaft 19 to rotate, so that the switching shaft 19 drives the positioning clamps 8 on both sides to rotate to a position relative to the through slot 9. Then the output shaft of the second motor 18 drives the lead screw 7 to rotate. The mold displacement member 11 threadedly connected to the outer wall of the lead screw 7 drives the die 3 to move. As the demolding movable member 5 moves, the demolding fixed member 4 pushes the demolding movable member 5 into the mold cavity 10 through the support plate 20, thereby removing the helmet formed inside. At this time, the elastic reset member 22 is compressed and generates elastic force.
[0057] After the helmet is demoulded, the elastic force of the elastic reset member 22 is used to move the demoulding movable member 5 to the initial position.
