Detailed Implementation

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1, referring to Figures 1-3 This is the first embodiment of the present invention. This embodiment provides a stamping die for the production of new energy vehicle parts. The stamping die for the production of new energy vehicle parts includes a stamping mechanism 1, a demolding mechanism 2 and a limit correction mechanism 3.

[0032] Specifically, the stamping mechanism 1 is used for stamping and forming automotive parts, including a lower die 11 and an upper die 12 for stamping and forming automotive parts, and the upper die 12 and the lower die 11 cooperate with each other. The stamping mechanism 1 can stamp and form box-shaped parts for new energy vehicles. This is existing technology. The working principle of this part is also existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here.

[0033] Specifically, the demolding mechanism 2 is installed on the stamping mechanism 1 to facilitate the demolding and removal of the stamped parts. It includes two push rods 21 that slide symmetrically on the lower die 11. Each push rod 21 has a push block 22 fixed at its upper end to push the stamped parts away from the lower die 11. The push block 22 is equipped with an opening and closing element 23 and has a liquid hole that cooperates with the opening and closing element 23. The stamping mechanism 1 is equipped with a liquid supply element 24 and a support element 25, and the liquid supply element 24 is connected to the push rods 21. A placement plate 26 is fixed on the liquid supply element 24 and the support element 25.

[0034] The inner wall of the lower die 11 has two grooves that mate with two top blocks 22. These grooves prevent the top blocks 22 from protruding from the lower die 11 after they move down, ensuring they are flush with the bottom of the inner wall. This ensures proper forming of the blank during stamping by the upper die 12 and lower die 11. After stamping, the top blocks 22, along with the ejector pin 21, move upwards, ejecting the formed parts from the lower die 11 for easy demolding. Several liquid holes are arranged in a circular array. The opening and closing mechanism 23 allows the liquid holes to be opened after the blank is placed on the placement plate 26. Pressure is applied to the support 25 and the liquid supply 24. As the placement plate 26 and the blank move down, the opening and closing part 23 opens. The release fluid is discharged from the liquid supply 24 through the ejector rod 21 and the ejector block 22 from the liquid hole, and then sprayed into the lower die 11. An isolation layer is formed between the lower die 11 and the workpiece, reducing the surface free energy, allowing the workpiece to easily leave the die, reducing the frictional resistance when the metal flows, reducing the stamping load, preventing scratches and wrinkles on the workpiece surface, and at the same time carrying away the heat generated during the stamping process, protecting the die and the workpiece, and extending the service life of the die.

[0035] Stamping release fluid is a functional processing aid between a metal workpiece and a mold. It is specifically designed to prevent the metal material from sticking to the mold surface during stamping, while providing lubrication, cooling, and protection. This is existing technology, which is well known to those skilled in the art and will not be elaborated here. The type of release fluid can be selected according to the actual situation. The mold surface should be cleaned manually regularly. There are two placement plates 26, which are symmetrically distributed. The ejector pin 21 and the lower mold 11 are sealed together. The ejector block 22 is sealed together when it moves down into the groove.

[0036] Specifically, the limit correction mechanism 3 is installed on the stamping mechanism 1 and the demolding mechanism 2 and is used to limit and correct the stamping blank. It includes multiple rollers 31 for limiting and correcting the stamping blank. The surfaces of the multiple rollers 31 are all fixedly fitted with rubber sleeves 32 to increase the limiting and correcting effect of the stamping blank. Transmission components 33 are installed on the placement plate 26 and the stamping mechanism 1. One end of the placement plate 26 is fixedly fitted with a limit block 34 by bolts. The upper end of the rollers 31 is rotatably fitted with a limit plate 35.

[0037] By setting the roller 31 and the rubber sleeve 32 thereon, the blank placed on the two placement plates 26 can be limited on both sides. During the placement process, the transmission component 33 can act on the rubber sleeve 32, so that the blank in contact with the rubber sleeve 32 is subjected to force. This avoids the blank not being in contact with the limiting block 34 when placed by manual operation. It can drive the blank to move on the placement plate 26. After the blank comes into contact with the limiting block 34, it can continue to act without affecting the stamping. This ensures that the blank is accurately positioned during stamping and placement, and plays a role in both limiting and correcting.

[0038] With the transmission component 33 in place, during the downward movement of the upper die 12, the transmission component 33 can act on the roller 31 and the rubber sleeve 32 again, so as to prevent the rubber sleeve 32 from failing to move the blank into place during placement, so that the side of the blank contacts and limits the limit block 34. There are two limit blocks 34. The position of the limit blocks 34 can be adjusted on the placement plate 26 and then fixed by bolts on it to meet the limit during the processing of blanks of different sizes. There are two limit plates 35. The roller 31 is rotatably connected to the limit plate 35 through the bearing. With the setting of the limit plate 35, when the upper die 12 moves upward after stamping, it plays the role of demolding when there are molded parts attached to it. The parts are removed during the upward movement of the upper die 12.

[0039] Example 2, refer to Figures 2-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0040] Specifically, the stamping mechanism 1 also includes a platform 13 located at the bottom of the lower die 11, and the lower die 11 is fixed to the top of the platform 13 by bolts. Support rods 14 are fixed at the four corners of the top of the platform 13. Support plates 15 are fixed at the upper ends of the support rods 14, and hydraulic cylinders 16 are fixed to the top of the support plates 15 by bolts. The upper die 12 is fixed to the output end of the hydraulic cylinder 16. Guide rods 17 slide on the top of the support plates 15, and the lower ends of the guide rods 17 are fixed to the top of the upper die 12. There are four support rods 14 and four guide rods 17, all of which pass through the support plates 15 to guide and limit the upper die 12, making the upper die 12 more stable when moving. By controlling the extension of the hydraulic cylinders 16, the upper die 12 moves down, and then the blank placed on the placement plate 26 and the lower die 11 cooperates with the lower die 11 to stamp and form the blank.

[0041] Specifically, the ejector rod 21 slides on the lower mold 11 and the platform 13. The ejector rod 21 has a channel 1 211, a channel 212 and an annular channel 1 213 respectively. The channel 212 is connected to the annular channel 1 213. Both the channel 1 211 and the annular channel 1 213 are connected to the liquid supply component 24. There are several channels 212, which are arranged in a circular array. The annular channel 1 213 is connected to the annular channel 3 223 through the channel 212.

[0042] Specifically, the top block 22 is provided with a groove 221, a second annular channel 222, a third annular channel 223, a third channel 224 and a through hole 225. The groove 221 is connected to the first channel 211 and the through hole 225 respectively. The third channel 224 is connected to the second annular channel 222 and the third annular channel 223 respectively. The third annular channel 223 is connected to the second channel 212. The opening and closing element 23 is installed in the through hole 225 and the liquid hole. There are several through holes 225 and several channels 224, which are arranged in a circular array. The second annular channel 222 and the third annular channel 223 are connected through the third channel 224.

[0043] Specifically, the liquid supply component 24 includes a cylinder 241 fixed on the platform 13. A piston 1 242 and a piston 243 slide on the inner wall of the cylinder 241 respectively. A piston rod 244 slides on the upper end of the cylinder 241, and the two ends of the piston rod 244 are fixed to the bottom of the placement plate 26 and the top of the piston 1 242 respectively. A short rod 245 slides on the piston 243, and the upper end of the short rod 245 is fixed to the bottom of the piston 1 242. A stop block 246 is fixed at the lower end of the short rod 245. The stop block 246 cooperates with the piston 243. A spring 247 is fixed between the bottom of the piston 243 and the inner wall of the cylinder 241.

[0044] Piston 242, piston 243, and piston rod 244 are all sealed to the cylinder 241. Short rod 245 is sealed to piston 243. The upper end of the cylinder 241, the hose 2412, the channel 211, the groove 221, and the through hole 225 are all filled with gas, which is incompressible under any conditions. This is prior art. The working principle of this part is also prior art, which can be clearly understood by those skilled in the art, and will not be described in detail here. Furthermore, the upper end of the cylinder 241 is provided with... The gas replenishment device can replenish gas after long-term use. This is existing technology and can be clearly understood by those skilled in the art, so it will not be described in detail here. After the billet is placed on the placement plate 26, the placement plate 26 moves down, which in turn drives the piston rod 244 and piston 242 to move. The gas in the tank 221 is drawn into the upper end of the cylinder 241 through the channel 211 and the hose 2412. Under the action of relative negative pressure, the opening and closing part 23 is gradually opened. The opening and closing part 23 keeps the annular channel 222 connected to the liquid hole.

[0045] The lower end of the cylinder 241 is connected to a one-way valve 248 and a one-way valve 249. The lower end of the one-way valve 248 is connected to a connecting pipe 2410, and the lower end of the one-way valve 249 is connected to a hose 2411. One end of the hose 2412 is fixed to the top rod 21 and connected to the ring channel 213. The upper end of the cylinder 241 is connected to the hose 2412. One end of the hose 2412 is fixed to the top rod 21 and connected to the channel 211. The inner wall of the platform 13 is fixed with a liquid tank 2413, and the lower end of the connecting pipe 2410 is connected to the liquid tank 2413. The lower end surface of the piston rod 244 is fitted with a spring 2414, and the two ends of the spring 2414 are fixed to the inner wall of the cylinder 241 and the top of the piston 242, respectively.

[0046] By setting one-way valve 248 and one-way valve 249, the release liquid in the liquid tank 2413 can enter the lower end of the cylinder 241 through the connecting pipe 2410, and then be discharged from the hose 2411. However, there will be no backflow, and it can only flow in one direction. After piston 242 moves down in the cylinder 241 and contacts piston 243, as piston 242 continues to move down, it can drive piston 243 to move down in the cylinder 241, which will push the release liquid in the lower end of the cylinder 241 into the channel 212 through one-way valve 249 and hose 2411. Then, it passes through the ring channel 223, the channel 224 and the ring channel 222 in sequence and is discharged from the liquid hole. It is sprayed by the nozzle 238 in the liquid hole. The short rod 245 passes through piston 243 and is slidably connected to it.

[0047] The spring 247, when piston 242 moves with short rod 245 but does not contact piston 243, supports piston 243, preventing it from moving. When piston 243 moves and compresses, it deforms, providing force for its subsequent reset. The short rod 245 and the stop block 246 ensure that piston 243 will not move when piston 242 moves downwards within cylinder 241 without contacting it. When piston 242 contacts piston 243, it can push it to move. The release fluid in the lower end of the cylinder 241 is discharged. During the reset process after the stamping is completed, when the piston rod 244 and piston 242 move upward to reset, piston 243 can be ensured to move to its original position. Then, the release fluid in the liquid tank 2413 is drawn into the lower end of the cylinder 241 through the connecting pipe 2410 and the one-way valve 248 to prepare for the next stamping. Through the setting of spring 3 2414, when piston 242 moves downward in the cylinder 241, it is stretched, providing force for the reset of piston 242 and piston rod 244.

[0048] Specifically, the support member 25 includes a vertical cylinder 251 fixed to the top of the platform 13, with a vertical rod 252 sliding on the vertical cylinder 251. A circular plate 253 slides on the inner wall of the vertical cylinder 251. The two ends of the vertical rod 252 are respectively fixed to the bottom of the placement plate 26 and the top of the circular plate 253. A spring 254 is fixed between the bottom of the circular plate 253 and the inner wall of the vertical cylinder 251. There are four support members 25, distributed at the four corners of the lower mold 11. Two support members 25 are provided at the bottom of each placement plate 26. Air holes are opened on the vertical cylinder 251, and the vertical rod 252 passes through the vertical cylinder 251. The cylinder 251 is slidably connected to it. With the setting of spring 254, after the blank is placed on the placement plate 26, the placement plate 26 moves down and drives the vertical rod 252 to move on the vertical cylinder 251, so that the circular plate 253 moves in the vertical cylinder 251 and compresses the spring 254 until the bottom of the blank contacts the top of the lower die 11, supporting the blank. When the blank is stamped and removed, under its rebound action, the placement plate 26, the vertical rod 252 and the circular plate 253 are reset, and then the piston rod 244 and the piston 242 move up and reset.

[0049] Example 3, referring to Figures 2-7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0050] Specifically, the transmission component 33 includes a connecting plate 335 fixed to the bottom of the placement plate 26. Two square rods 336 are symmetrically fixed on one side of the connecting plate 335, and a square plate 337 is fixedly sleeved on the surface of the square rods 336 by bolts. The roller 31 is rotatably connected to the square plate 337. A synchronous disc 331 rotates on the lower surface of the roller 31. A torsion spring 332 is sleeved on the lower surface of the roller 31, and the two ends of the torsion spring 332 are respectively fixed to the inner wall of the synchronous disc 331 and the surface of the roller 31. A synchronous belt 333 is driven sleeved on the surface of the synchronous disc 331. A gear ring 334 is fixed at the bottom of the synchronous disc 331. A circular sleeve 338 rotates on the square plate 337, and a drive rod 339 slides on the inner wall of the circular sleeve 338. A ball bearing 3310 is embedded in the inner wall of the circular sleeve 338. A guide groove 3319 is opened on the surface of the drive rod 339, and the ball bearing 3310 slides in the guide groove 3319.

[0051] There are two connecting plates 335, and one connecting plate 335 is fixed to the bottom of each of the two placement plates 26. Two square rods 336 are provided on one connecting plate 335. There are two square plates 337, which are sleeved on the surface of the square rods 336 on the two connecting plates 335. The square plates 337 can be adjusted on the square rods 336 and then fixed by bolts on the square plates 337, thereby adjusting the position of the rollers 31 and the rubber sleeves 32 to meet the processing limit requirements of different blanks. The rollers 31 are rotatably connected to the square plates 337 through bearings. The synchronous discs 331 are rotatably connected to the rollers 31 through bearings. Three rollers 31 are provided on one square plate 337. The middle synchronous disc 331 is connected to the other two synchronous discs 331 through two synchronous belts 333. The round sleeve 338 is rotatably connected to the square plate 337 through bearings. The ball bearing 3310 is rotatably connected to the round sleeve 338. The gear 3312 meshes with the gear rings 334 on the three middle synchronous discs 331.

[0052] With the torsion spring 332 in place, when the blank is placed directly on the placement plate 26, with its sides in contact with the rubber sleeve 32 and its rear side in contact with or not in contact with the limiting block 34, the placement plate 26 moves downward, causing the connecting plate 335, square rod 336, square plate 337, and round sleeve 338 to move downward. This causes the ball bearings 3310 inside the round sleeve 338 to move within the guide groove 3319, thereby causing the round sleeve 338 to rotate. This causes the ratchet 3311 to rotate, driving the gear 3312 to rotate, which in turn causes the central gear ring 334 and the timing disc 331 to rotate. Under the drive of the timing belt 333, multiple timing discs 33... 1. Rotation causes the torsion spring 332 to undergo torsional deformation, applying force to the roller 31. The rubber sleeve 32 applies force to the blank in contact with the limiting block 34 to ensure its state, and applies force to push the blank that is not in contact with the limiting block 34 to contact and limit it. When it is pushed in laterally from the front side of the placement plate 26, although the rubber sleeve 32 can drive the roller 31 to rotate and the torsion spring 332 to deform, providing a reverse action, as the placement plate 26 moves down, the drive synchronous disk 331 rotates to eliminate this reverse action, and the limiting plate 35 is slidably sleeved on the surface of the drive rod 339.

[0053] A ratchet 3311 is fixedly fitted on the surface of the round sleeve 338. A gear 3312 is fixedly fitted on the outer surface of the ratchet 3311, and the gear 3312 meshes with the gear ring 334. A horizontal plate 3313 is fixed to the lower end of the push rod 21 by bolts, and a slider 3314 is fixedly fitted on both ends of the horizontal plate 3313 by bolts. A push block 3315 is fixed to the lower end of the drive rod 339 through the slider 3314 by bolts. A fixing plate 3316 is fixed on both sides of the upper mold 12, and a square frame 3317 is fixedly fitted on the surface of the fixing plate 3316 by bolts. A fixing block 3318 is fixed on the surface of the square frame 3317, and the upper end of the drive rod 339 is fixed to the bottom of the fixing block 3318.

[0054] With the ratchet 3311 in place, when the sleeve 338 and the drive rod 339 move relative to each other, the sleeve 338 needs to drive the gear 3312 to rotate when it rotates. This allows the gear 3312 to rotate normally in one direction. When the sleeve 338 does not need to drive the gear 3312 to rotate, the gear 3312 will not rotate, thus preventing the gear ring 334 from rotating. The slider 3314 can be adjusted on the horizontal plate 3313 and fixed with bolts after adjustment. There are four fixing plates 3316, symmetrically distributed on both sides of the upper mold 12. The drive rod 339 passes through the slider 3314 and slides with it. The square frame 3317 can be adjusted on the fixing plate 3316 and fixed with bolts after adjustment.

[0055] With the push block 3315 in place, during stamping, as the upper die 12 moves downward, the fixing plate 3316, the square frame 3317, the fixing block 3318, and the drive rod 339 move downward. The downward movement of the drive rod 339 causes the push block 3315 to move downward, and the horizontal plate 3313, the ejector rod 21, the ejector block 22, and the slider 3314 move downward. After the ejector block 22 moves downward into the groove in the lower die 11, the ejector rod 21, the horizontal plate 3313, and the slider 3314 no longer move. The push block 3315 separates from the slider 3314 and, with the downward movement of the upper die 12, cooperates with the lower die 11 to stamp and form the blank.

[0056] During the process of the upper die 12 moving upward and resetting after stamping, the drive rod 339 drives the push block 3315 to move upward and contact the bottom of the slider 3314, thereby causing the horizontal plate 3313, the ejector rod 21 and the ejector block 22 to move upward, ejecting the formed blank in the lower die 11 and demolding it. During the downward stamping process of the lower die 11, the drive rod 339 can cause the ball 3310 to move in the guide groove 3319, causing the sleeve 338 to rotate in the opposite direction and then in the original direction. Then, under the action of the ratchet 3311, the gear 3312 does not rotate at first, and then rotates, thereby causing the synchronous disk 331 to rotate, and then torsion spring 332 to be twisted again, which can act on roller 31 and rubber sleeve 32 again, so as to prevent the rubber sleeve 32 from failing to move the blank into place during placement, and prevent the side of the blank from contacting and limiting the limit block 34.

[0057] A round block 27 is fixedly sleeved on the lower end surface of the ejector rod 21 by bolts. A spring 28 is movably sleeved on the surface of the ejector rod 21, and the two ends of the spring 28 abut against the inner wall of the platform 13 and the bottom of the round block 27, respectively. With the setting of the spring 28, when the ejector rod 21 and the ejector block 22 move upward with the horizontal plate 3313 to eject the part out of the mold, the round block 27 moves upward with the ejector rod 21, causing the spring 28 to be compressed, providing a force for the reset of the round block 27, the ejector rod 21 and the ejector block 22. Rollers 29 arranged in a linear array rotate on the placement plate 26. The rollers 29 are rotatably connected to the placement plate 26 through bearings, reducing the friction between the blank and the placement plate 26 when the blank is placed on it, making the movement of the blank more smooth when the rubber sleeve 32 drives it.

[0058] Example 4, refer to Figures 1 to 7 This is the fourth embodiment of the present invention, which is based on the first three embodiments.

[0059] Specifically, the guide groove 3319 includes groove 1 33191, groove 2 33192, groove 3 33193, groove 4 33194 and groove 5 33195. Groove 5 33195, groove 4 33194, groove 1 33191, groove 2 33192 and groove 3 33193 are distributed sequentially from top to bottom and are interconnected with each other.

[0060] When the ball bearing 3310 moves within slots 33191, 33193, and 33195, it does not cause the sleeve 338 to rotate. When the ball bearing 3310 moves within slots 33192 and 33194, it causes the sleeve 338 to rotate. When the blank is placed on the placement plate 26 and moves up and down, the ball bearing 3310 moves from slot 33191 through slot 2 to slot 33193, causing the sleeve 338 and ratchet 3311 to rotate. When the drive rod 339 moves down with the upper mold 12, the ball bearing 3310 first moves from slot 33191 through slot 2 to slot 33193. 3193 enters slot 1 (33191) through slot 2 (33192), causing the sleeve 338 to rotate. The inner ring of the ratchet 3311 rotates, while the outer ring does not rotate, thus preventing the gear 3312 from rotating. Then, it enters slot 5 (33195) through slot 4 (33194) from slot 1 (33191), enabling the sleeve 338 and ratchet 3311 to rotate together, thereby causing the gear 3312 to rotate again, acting on the roller 31 and the rubber sleeve 32. This prevents the rubber sleeve 32 from failing to move the blank into place during placement, thus preventing the side of the blank from contacting and limiting the limit block 34.

[0061] Specifically, the opening and closing component 23 includes a valve column 231 that slides within the top block 22, with both ends of the valve column 231 extending into the liquid hole and the through hole 225 respectively. A piston 232 slides within the through hole 225 and is fixed to one end of the valve column 231. A liquid groove 233 is provided at one end of the valve column 231, and circular holes 234 arranged in a circumferential array are provided at one end of the valve column 231. The circular holes 234 communicate with the liquid groove 233. A spring 235 is fitted at the end of the valve column 231 near the piston 232, with both ends of the spring 235 fixed to the surface of the piston 232 and the inner wall of the through hole 225 respectively. A limiting groove 236 is provided on the inner wall of the liquid hole, and a limiting post 237 is fixed at one end of the valve column 231. The limiting post 237 slides within the limiting groove 236. A nozzle 238 is fixed on the inner wall of the liquid hole, and a baffle 36 is fixed on the top of the square plate 337.

[0062] There are several opening and closing components 23 arranged in a circular array. A seal is formed between piston 232 and through hole 225. The valve stem 231 is sealed between the top block 22 and the liquid hole. When piston 242 moves downward within cylinder 241, the gas in groove 221 gradually decreases, drawing piston 232 to move within through hole 225, thereby moving valve stem 231 and connecting through hole 225 with annular channel 222. This allows piston 243 to move downward. The pressure forces the release fluid entering the second ring channel 222 into the liquid tank 233 through the through hole 225. It is then sprayed out through the nozzle 238 installed in the liquid hole. As the first piston 242 continues to move downward, the third piston 232 and the valve column 231 continue to move. The through hole 225 on the valve column 231 is blocked by the top block 22 and is no longer connected to the second ring channel 222, thus closing it. At the same time, one end of the valve column 231 does not detach from the liquid hole, thus closing it and preventing leakage of the release fluid during the stamping process.

[0063] By setting spring 5 235, the piston 3 232 is stretched when it moves in the through hole 225, providing force for the subsequent reset of piston 3 232 and valve column 231. The valve column 231 and piston 3 232 are guided and limited by the limiting groove 236 and limiting post 237, so that valve column 231 and piston 3 232 will not rotate when moving.

[0064] During use, the blank is positioned and corrected as follows: the blank is placed on the placement plate 26, and the weight of the blank causes the placement plate 26 to move downward. The transmission component 33 drives the roller 31 and the rubber sleeve 32 to rotate, pushing the blank to fit against the limiting block 34, thus completing the initial positioning. Before the upper die 12 moves downward to press, the transmission component 33 drives the roller 31 a second time to ensure accurate positioning of the blank and avoid deviation.

[0065] Release fluid spraying: The placement plate 26 moves down, causing the piston rod 244 and piston 1 242 of the liquid supply component 24 to move, opening and closing component 23. At the same time, piston 243 is pressed to spray the release fluid in the liquid tank 2413 through hose 2412, push rod 21 and push block 22 from the nozzle 238 in the liquid hole, evenly covering the inner wall of the lower mold 11 to form a lubricating, cooling and isolation layer.

[0066] Stamping: The hydraulic cylinder 16 drives the upper die 12 to move down, and the guide rod 17 guides to ensure smooth stamping. The upper die 12 and the lower die 11 cooperate to stamp the blank into shape. During the stamping process, the release fluid continuously plays a lubricating and cooling role, reducing friction and heat.

[0067] Automatic demolding: After stamping is completed, the upper mold 12 moves up a certain distance, and the ejector pin 21 and ejector block 22 move up to eject the molded part out of the lower mold 11, realizing automatic demolding; at the same time, the liquid supply part 24 is reset and absorbs new demolding liquid to prepare for the next stamping.

[0068] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention 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 the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
