Description

Technical Field

[0001] This invention relates to the field of shoe sole demolding auxiliary equipment, and in particular to a demolding auxiliary equipment and demolding process for the soles of combat boots, training shoes, and leather shoes. Background Technology

[0002] In the manufacturing of combat boots, training shoes, and leather shoes, the bonding process between the sole and upper is crucial in determining the shoe's lifespan and performance. Currently, the mainstream advanced shoe manufacturing processes mainly include compression molding and direct injection molding. While these two processes can significantly improve the abrasion resistance, flexural strength, and bonding strength between the sole and upper, many problems still exist in production practice, especially in the final demolding stage. Existing technologies often use ejector pin structures for demolding.

[0003] During the demolding process of the shoe sole, the existing ejector pin structure lifts the sole out of the mold. The ejector pins make point contact, and the ejection force is concentrated on a few points. If these points bear excessive pressure, it can easily cause the material to turn white or even be punctured. Furthermore, all the ejector pins move simultaneously, mechanically lifting the entire sole in an instant, but there is often a vacuum between the sole and the mold cavity. If a certain part of the sole is firmly attached, this instantaneous impact may cause the sole to be stretched and deformed. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of stress concentration caused by point contact of ejector pins in the prior art, and the easy occurrence of whitening, tearing or stretching deformation of the sole due to vacuum adsorption during simultaneous ejection. Therefore, this invention proposes an auxiliary device and demolding process for demolding the soles of combat boots, training shoes and leather shoes.

[0005] To achieve the above objectives, the present invention employs the following techniques: An auxiliary device for demolding the soles of combat boots, training shoes, and leather shoes includes a base and a frame fixed on the base. A cylinder is fixed on the frame, and an upper mold core is fixed at the output end of the cylinder. A base plate is fixed on the base, and two symmetrical mounting plates are fixed on the base plate. A drive motor is fixed on one of the mounting plates, and a connecting shaft is fixed at the output end of the drive motor. Two sets of swing components are provided on the connecting shaft, and a transmission rod is rotatably mounted on each swing component. A lower mold is fixed on the base plate by two support frames. Two mounting brackets are fixed on the base plate, and a limiting plate is fixed between the two mounting brackets. Multiple pushing mechanisms adapted to the transmission rod are movably mounted on the limiting plate, and two symmetrical linkage mechanisms are fixed on the limiting plate. The drive motor drives the connecting shaft to move the connected swing assembly, causing the transmission rods in the same group to move in a wave-like motion in the vertical direction. Through the cooperation of the transmission rods and the push mechanism, multiple push mechanisms make a wave-like pushing motion.

[0006] Further description of the above-mentioned auxiliary device for demolding the soles of combat boots, training shoes, and leather shoes: The pushing mechanism includes a lifting rod that slides on a limiting plate. The lifting rod is adapted to a vertically arranged transmission rod. A limiting cover is fixed on the lifting rod. A return spring connected to the limiting plate is fixed on the top wall of the inner cavity of the limiting cover. A vibration mechanism and a contact assembly are fixed on the lifting rod.

[0007] Further description of the above-mentioned auxiliary device for demolding the soles of combat boots, training shoes, and leather shoes: The swing assembly includes an eccentric wheel fixed on a connecting shaft. Multiple eccentric wheels in the same group are axially distributed on the connecting shaft. The phase difference between two adjacent eccentric wheels in the circumferential direction is equal. A connecting block is rotatably mounted on the eccentric wheel, and a fixing rod that rotatably cooperates with the transmission rod is fixed on the connecting block.

[0008] Further description of the above-mentioned auxiliary device for demolding the soles of combat boots, training shoes, and leather shoes: The contact assembly includes a connecting plate fixedly connected to the top of the lifting rod. A plurality of guide posts penetrating the lower mold are fixed on the connecting plate. A base plate is fixed on the guide posts, and an ejector plate is fixed on the base plate.

[0009] Further description of the above-mentioned auxiliary device for demolding the soles of combat boots, training shoes, and leather shoes: The vibration mechanism includes a fixed block fixed to a lifting rod, a plurality of mounting tubes are fixed through the fixed block, a connecting spring is fixed to the bottom wall of the inner cavity of each mounting tube, a sliding rod connected to the connecting spring is slidably connected to the inner cavity of each mounting tube, and a vibration head is fixed on each sliding rod.

[0010] Further description of the above-mentioned auxiliary device for demolding the soles of combat boots, training shoes, and leather shoes: The linkage mechanism includes two connecting rods fixed to the limiting plate. The ends of the two connecting rods away from the limiting plate are rotatably connected to a rotating plate. One end of each of the two rotating plates is provided with a second sliding groove. The inner cavity of each of the two second sliding grooves is slidably provided with a limiting post. A sliding plate penetrating the side of the lower mold is fixed on one side of each limiting post. An ejector block is fixed on the sliding plate.

[0011] Further description of the above-mentioned auxiliary device for demolding the soles of combat boots, training shoes, and leather shoes: Each of the two rotating plates has a sliding groove at its other end. A connecting column is slidably arranged in the inner cavity of each of the two sliding grooves. A straight plate is fixedly fixed on both connecting columns, and the straight plate is fixedly connected to the transmission rod.

[0012] This invention also discloses a demolding process for a demolding aid device for the soles of combat boots, training shoes, and leather shoes, comprising the following steps: S1. Select demolding method Depending on the adhesion of the sole to the mold, select the rotation direction of the drive motor so that the ejection action is pushed from both ends to the middle or from the middle to both ends. S2, Start the driver system Start the drive motor, which drives the connecting shaft to rotate, causing multiple eccentric wheels fixed on the connecting shaft to rotate synchronously; S3, Begin demolding By setting the phase difference of the eccentric wheel, multiple transmission rods are driven to make a wave-like motion in the vertical direction; the motion of the transmission rods is transmitted to the lifting rod in the pushing mechanism, so that multiple ejector plates are ejected in a wave-like manner in the bottom area of ​​the shoe sole, forming a surface contact ejection. During the lifting and lowering process of the lifting rod, the vibrating head in the vibration mechanism comes into contact with the lower mold, generating reciprocating micro-vibrations, which disrupt the molecular adhesion between the shoe sole and the mold. When the transmission rod installed at the trough position rises, it drives the ejector block to slide inward through the linkage mechanism, pushing the side of the shoe sole to assist in demolding; S4. Restore initial state After the connecting shaft rotates an integer number of revolutions, multiple swing components and transmission rods return to their initial state. The reset spring resets the push mechanism, and the equipment returns to its initial state, ready for the next demolding cycle.

[0013] In summary, due to the adoption of the above-mentioned technology, the beneficial effects of this invention, including the auxiliary equipment and demolding process for demolding the soles of combat boots, training shoes, and leather shoes, are as follows: 1. This device, through the coordinated operation of the drive motor, swing assembly, and transmission rod, enables the pushing mechanism to perform a wave-like ejection motion. Combined with the surface-contact ejection plates, this creates a wave-like ejection of the sole from the lower mold cavity. The rotation direction of the drive motor can be adjusted, allowing the wave to propel from either end towards the center or vice versa. The multiple ejection plates form surface contact with the sole surface, and the wave-like ejection force ensures that the stress area on the sole changes continuously but maintains a large, uniform load-bearing area. This reduces localized pressure and effectively solves the problem of material whitening or puncture caused by stress concentration. The direction of the wave propagation is selected based on which part of the sole is more firmly attached to the mold; the most firmly attached area is ejected last, while the surrounding area has already detached from the mold, thus only needing to overcome localized adhesion forces. This gradual demolding method avoids the enormous impact of instantaneous overall ejection in traditional processes, thereby reducing the risk of the sole being stretched and deformed.

[0014] 2. This device, through the coordinated operation of the drive motor, swing assembly, transmission rod, and pushing mechanism, enables gas exchange during the wave-like ejection process. As the wave advances, the area in front of the crest is actively compressed, expelling air; while the area behind the crest forms a negative pressure, actively drawing in air. This simultaneous gas exchange during ejection breaks the vacuum adhesion between the sole and the mold cavity, eliminating the need for an additional air blowing device, simplifying the structure, and improving demolding reliability.

[0015] 3. This device, through the linkage mechanism, can generate vibration during the demolding process, thereby breaking the intermolecular forces between the sole material and the mold surface. When the lifting rod rises, the vibrating head contacts the lower mold and compresses the connecting spring. After the lifting rod falls and resets, the connecting spring releases its elasticity, causing the vibrating head to reciprocate and impact the lower mold, generating high-frequency micro-vibrations. This micro-vibration can break the intermolecular forces between the sole material and the mold surface, causing micro-separation at the adhesion interface, thus effectively solving the stubborn sticking problem that conventional mechanical ejection cannot handle.

[0016] 4. This device, through its linkage mechanism, can assist in lateral demolding and protect the sides of the shoe sole. By raising the transmission rod, the straight plate is driven to rise, and the straight plate drives the rotating plate to rotate through the connecting column. The rotating plate, through the cooperation of the sliding groove and the limiting column, drives the sliding plate and the ejector block to slide inward, pushing the sides of the shoe sole. This allows the shoe sole to receive auxiliary thrust from the sides while being pushed out from the bottom, achieving multi-directional coordinated demolding and avoiding jamming or damage to the sides of the shoe sole caused by ejection in a single direction.

[0019] The following will describe, with reference to the accompanying drawings of the embodiments of the present invention, a clear and complete description of an auxiliary device and demolding process for demolding the soles of combat boots, training shoes, and leather shoes according to the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1 As shown, an auxiliary device for demolding the soles of combat boots, training shoes, and leather shoes includes a base 10 and a frame 11 fixed on the base 10. The frame 11 consists of four support columns and a support plate. A cylinder 12 is fixed on the frame 11. The cylinder 12 is fixedly installed on the support plate of the frame 11. An upper mold core 13 is fixed at the output end of the cylinder 12. The upper mold core 13 is the upper mold used for producing shoe soles.

[0021] like Figure 2 and Figure 3As shown, a base plate 20 is fixed on the base 10, and two symmetrical mounting plates 21 are fixed on the base plate 20. A drive motor 22 is fixed on one of the mounting plates 21, and a connecting shaft 25 is fixed to the output end of the drive motor 22. The connecting shaft 25 is rotatably mounted on the two mounting plates 21 and fixedly connected to the output end of the drive motor 22. During the rotation of the output end of the drive motor 22, it can drive the connecting shaft 25 to rotate. Two sets of swing components 23 are provided on the connecting shaft 25. A transmission rod 24 is rotatably mounted on each swing component 23. The connecting shaft 25 drives the swing components 23 in the same group to move, so that the multiple transmission rods 24 in the same group move in a wave-like manner in the vertical direction. A lower mold 27 is fixed on the base plate 20 by two support frames 26. The two support frames 26 are fixed on the base plate 20, and the lower mold 27 is fixed between the two support frames 26. The lower mold 27 and the upper mold core 13 cooperate to form a closed shoe mold forming space. An injection joint is installed on the lower mold 27. The injection joint serves as an inlet channel for the injection liquid, which can accurately inject the molten injection liquid into the inner cavity of the lower mold 27. Two mounting brackets 28 are fixed on the base plate 20. A limiting plate 29 is fixed between the two mounting brackets 28. The limiting plate 29 has multiple mounting holes that are compatible with the transmission rod 24, so that the transmission rod 24 can only move up and down. Multiple pushing mechanisms 30 that are compatible with the transmission rod 24 are movably mounted on the limiting plate 29. The limiting plate 29 has sliding holes for mounting the pushing mechanisms 30, which restrict the movement direction of the pushing mechanisms 30. Two symmetrical linkage mechanisms 40 are fixed on the limiting plate 29. The linkage mechanisms 40 are connected to the transmission rod 24 and can push the side of the shoe sole when demolding as the transmission rod 24 moves.

[0022] Among them, the drive motor 22 drives the connecting shaft 25 to move the connected swing component 23. Under the limitation of the mounting hole on the limiting plate 29, the swing component 23 of the same group moves in a wave-like manner in the vertical direction with the transmission rod 24 of the same group. Through the cooperation of the transmission rod 24 and the push mechanism 30, the rise and fall of the transmission rod 24 can make the push mechanism 30 rise and fall accordingly, so that multiple push mechanisms 30 are pushed out in a wave-like manner. Through multiple wave-shaped pushing mechanisms 30, the entire bottom surface of the sole is subjected to force simultaneously and in surface contact. As the waves advance, the force area changes continuously, but it always bears a large area evenly with minimal local pressure, thus avoiding the phenomenon of whitening or puncture caused by excessive force on the same part of the sole. like Figure 8 and Figure 9As shown, when the drive motor 22 drives the connecting shaft 25 to rotate clockwise, the two sets of swing components 23 move from both ends to the middle. When the drive motor 22 drives the connecting shaft 25 to rotate counterclockwise, the two swing components 23 move from the middle to both ends. The ejection direction is selected according to the structural characteristics of the sole. If the middle part is firmly glued, it is pushed from both ends to the middle. If the two ends are firmly glued, it is pushed from the middle to both ends. The firmly glued area is finally lifted up. Moreover, even when the surrounding area has already detached, the ejection force only needs to overcome the local adsorption force, which can reduce tensile deformation. In addition, during the wave-like propulsion process, when the wave crest advances, the area in front of the crest is actively squeezed to expel air, and when the wave crest retreats, the area behind the crest forms a negative pressure, actively drawing in air. During the ejection process, gas exchange is actively carried out to completely break the vacuum. During the demolding process, the vacuum adsorption is actively broken, eliminating the need for additional air blowing.

[0023] like Figure 4 and Figure 5 As shown, the pushing mechanism 30 includes a lifting rod 31 that slides on the limiting plate 29. The lifting rod 31 is adapted to the vertically arranged transmission rod 24. Each lifting rod 31 has a cylindrical hole that is adapted to the corresponding position of the transmission rod 24. In the initial state, the top end of the transmission rod 24 is in contact with the top wall of the cylindrical hole. Figure 4 As shown, a limit cover 33 is fixed on the lifting rod 31. The limit cover 33 is open downwards. A return spring 32 connected to the limit plate 29 is fixed on the top wall of the inner cavity of the limit cover 33. The return spring 32 is initially in a compressed state. The reset spring 32 is connected between the limiting plate 29 and the limiting cover 33 to reset the raised lifting rod 31. At the same time, the limiting cover 33 enables the lifting rod 31 to reset to its initial position. The lifting rod 31 is fixed with a vibration mechanism 34 and a contact component 35. The vibration mechanism 34 can generate micro-vibration after the lifting rod 31 is raised and reset. The contact component 35 contacts the sole of the shoe in the inner cavity of the lower mold 27.

[0024] Under the action of multiple wave-shaped transmission rods 24, the lifting rod 31 moves in a wave-like manner, causing multiple contact components 35 to move in a wave-like manner, applying a pushing force to different positions of the shoe sole in the inner cavity of the lower mold 27, and lifting the shoe sole out of the inner cavity of the lower mold 27.

[0025] like Figure 6 and Figure 7 As shown, the swing assembly 23 includes an eccentric wheel 231 fixed on the connecting shaft 25. Multiple eccentric wheels 231 in the same group are axially distributed on the connecting shaft 25. The phase difference between two adjacent eccentric wheels 231 in the circumferential direction is equal. The phase difference is the angle between two adjacent eccentric wheels 231, that is, the included angle between two adjacent eccentric wheels 231 is set to be equal. A connecting block 232 is rotatably mounted on the eccentric wheel 231. A fixed rod 233 is fixed on the connecting block 232 and rotates with the transmission rod 24. The connecting block 232 has a groove, and the fixed rod 233 fixes the inner cavity of the groove. One end of the transmission rod 24 is sleeved on the fixed rod 233 and rotates with the fixed rod 233. The connecting blocks 232 driven by each eccentric wheel 231 will reach the top of the stroke in sequence, thereby driving the transmission rod 24 to generate continuous biomimetic wave motion.

[0026] like Figure 10 As shown, the contact component 35 includes a connecting plate 351 fixedly connected to the top of the lifting rod 31. Multiple guide posts 352 penetrating the lower mold 27 are fixed on the connecting plate 351. The guide posts 352 penetrating the lower mold 27 provide guidance for the rise of the guide posts 352. A base plate 353 is fixed on the guide posts 352. The base plate 353 is made of metal, and can be selected from aluminum alloy or stainless steel plate. An ejector plate 354 is fixed on the base plate 353. The ejector plate 354 is made of high temperature resistant silicone. The surface of the ejector plate 354 is designed to match the contour of the bottom surface of the shoe sole, so as to achieve surface contact with the shoe sole.

[0027] like Figure 10 As shown, the vibration mechanism 34 includes a fixing block 341 fixed on the lifting rod 31. The lifting rod 31 passes through the fixing block 341 and is fixedly connected to the fixing block 341. Multiple mounting tubes 344 are fixed through the fixing block 341. A connecting spring 343 is fixed to the bottom wall of the inner cavity of each mounting tube 344. A sliding rod 342 connected to the connecting spring 343 slides in the inner cavity of each mounting tube 344. The connecting spring 343 is fixed between the sliding rod 342 and the bottom wall of the inner cavity of the mounting tube 344. The connecting spring 343 is in an extended state under normal conditions. A vibration head 345 is fixed on each sliding rod 342. The vibration head 345 is made of silicone. During the upward movement of the lifting rod 31, the vibrating head 345 contacts the lower mold 27. As the lifting rod 31 rises, the sliding rod 342 connected to the vibrating head 345 compresses the connecting spring 343. After the lifting rod 31 returns to its original position, the elastic force stored in the connecting spring 343 causes the sliding rod 342 and the vibrating head 345 to rise. After hitting the lower mold 27, they are compressed again. This cycle repeats, causing the vibrating head 345 to repeatedly hit the lower mold 27, creating up-and-down vibrations. This micro-vibration can disrupt the intermolecular forces at the adhesion interface, causing microscopic separation between the sole and the mold, thus solving the stubborn sticking problem that conventional mechanical ejection cannot handle.

[0028] like Figure 11As shown, the linkage mechanism 40 includes two connecting rods 45 fixed on the limiting plate 29. The two connecting rods 45 are respectively fixed on both sides of the limiting plate 29. The ends of the two connecting rods 45 away from the limiting plate 29 are rotatably connected to the rotating plate 44. One end of the two rotating plates 44 is provided with a second sliding groove 48. The inner cavity of the two second sliding grooves 48 is slidably provided with a limiting post 49. A sliding plate 46 that penetrates the side of the lower mold 27 is fixed on one side of each limiting post 49. The limiting post 49 is fixed on the sliding plate 46 and can slide in the inner cavity of the second sliding groove 48. An ejector block 47 is fixed on the sliding plate 46. The ejector block 47 is made of high temperature resistant silicone and is similar to the side profile of the shoe sole. Both rotating plates 44 have a sliding groove 43 at their other ends. A connecting post 42 is slidably installed in the inner cavity of each sliding groove 43. A straight plate 41 is fixed on both connecting posts 42. The two connecting posts 42 are fixed to both ends of the straight plate 41 and slide in the inner cavity of the sliding groove 43, thereby causing the rotating plate 44 to rotate. The straight plate 41 is fixedly connected to the transmission rod 24. The straight plate 41 can rise with the transmission rod 24. The rotating plate 44 is connected to the transmission rod 24 at the trough position, so that the straight plate 41 can only rise and will not fall with the transmission rod 24, thus not affecting the use of the device or the forming of the shoe sole.

During the lifting and lowering process of the lifting rod 31, the vibrating head 345 in the vibration mechanism 34 contacts the lower mold 27, generating reciprocating micro-vibrations, which disrupt the molecular adsorption force between the shoe sole and the mold; when the lifting rod 31 rises, the vibrating head 345 contacts the lower mold 27, compressing the connecting spring 343; after the lifting rod 31 falls back to its original position, the connecting spring 343 releases its elastic force, causing the vibrating head 345 to repeatedly strike the lower mold 27, forming up-and-down vibrations; When the transmission rod 24 installed at the trough position rises, it drives the ejector block 47 to slide inward through the linkage mechanism 40, pushing the side of the shoe sole to assist in demolding; when the transmission rod 24 rises, it drives the straight plate 41 to rise, and the straight plate 41 drives the rotating plate 44 to rotate through the connecting column 42. The rotating plate 44 drives the sliding plate 46 and the ejector block 47 to slide inward through the cooperation of the second slide groove 48 and the limiting column 49, pushing the side of the shoe sole. S4. Restore initial state After the connecting shaft 25 rotates an integer number of revolutions, the multiple swing components 23 and the transmission rod 24 return to their initial state. The reset spring 32 resets the push mechanism 30, and the equipment returns to its initial state, ready for the next demolding cycle.

8. A demolding process based on the demolding auxiliary equipment for the soles of combat boots, training shoes, and leather shoes according to any one of claims 1-7, characterized in that, Includes the following steps: S1. Select demolding method Depending on the adhesion of the sole to the mold, select the rotation direction of the drive motor (22) so that the ejection action is pushed from both ends to the middle or from the middle to both ends; S2, Start the driver system Start the drive motor (22), which drives the connecting shaft (25) to rotate, causing multiple eccentric wheels (231) fixed on the connecting shaft (25) to rotate synchronously; S3, Begin demolding By setting the phase difference of the eccentric wheel (231), multiple transmission rods (24) are driven to make wave-like motion in the vertical direction; the motion of the transmission rods (24) is transmitted to the lifting rod (31) in the push mechanism (30), so that multiple ejector plates (354) are ejected in sequence and wave-like in the bottom area of ​​the shoe sole, forming surface contact ejection; During the lifting process of the lifting rod (31), the vibrating head (345) in the vibration mechanism (34) comes into contact with the lower mold (27) and generates reciprocating micro-vibrations, which destroy the molecular adsorption force between the sole and the mold. When the transmission rod (24) installed at the trough position rises, it drives the ejector block (47) to slide inward through the linkage mechanism (40), pushing the side of the shoe sole to assist in demolding; S4. Restore initial state After the connecting shaft (25) rotates an integer number of revolutions, multiple swing components (23) and transmission rod (24) return to their initial state. The reset spring (32) resets the push mechanism (30), and the equipment returns to its initial state, ready for the next demolding cycle.
