Description

Technical Field

[0001] This application relates to the field of automotive lighting technology, and in particular to a stamping equipment for processing automotive lighting housings. Background Technology

[0002] In the automotive manufacturing industry, the headlight housing is a key component of a car's appearance and function, and its forming precision directly affects the headlight's sealing performance, optical performance, and assembly compatibility. As the automotive industry moves towards lightweighting and personalization, headlight housings are increasingly made from sheet metal through stamping processes, placing higher demands on the processing stability, automation level, and ease of product handling of stamping equipment.

[0003] Existing automotive headlight housing stamping equipment typically involves placing a metal sheet in a pre-set position on the lower die, with a drive mechanism pressing down the upper die to form the sheet metal. After forming, a buffer spring is usually used as the ejection force, and the release of the spring pushes the headlight housing out of the lower die. However, this ejection method has a relatively small ejection force. Not only is it difficult to smoothly push open the formed headlight housing due to insufficient force, but uneven ejection force can also cause the product to get stuck in the die, making it impossible to completely separate the product from the die. This increases the difficulty of picking up and putting down the product, reduces production efficiency, and further exacerbates the lack of coordination between the various structures, resulting in a complex equipment structure and poor synchronization of actions. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of this application are as follows: (1) This invention proposes a stamping equipment for processing vehicle headlight housings. The equipment includes a sleeve, a insert plate, a sleeve, a second insert plate, a stop block, a buffer spring, and a blocking assembly. A cylinder drives the upper die to move vertically downwards, simultaneously moving the sleeve, insert plate, and blocking assembly downwards. After the insert plate contacts the second insert plate, it causes the second insert plate, sleeve, and stop block to slide vertically down along the mounting groove. When the stop block slides into the limiting groove, the vertical movement of the sleeve and insert plate is restricted. The upper die continues to move downwards, causing the insert plate to push the second insert plate within the sleeve and compress the buffer spring again. After the insert plate has completely passed through, the second insert plate returns to its horizontal position. Finally, the linkage mechanism drives the limiting assembly to complete the limiting of the metal plate. In position, the cylinder continues to drive the upper mold to move down until it fits with the lower mold to complete the stamping. After stamping, the cylinder drives the upper mold to move up and reset, simultaneously driving sleeve one, insert plate one, and the blocking assembly to move up. The linkage mechanism drives the lifting assembly to eject the product. After insert plate one and insert plate two come into contact again, they drive sleeve two and the stop block to slide up. The stop block slides out of the limit groove one. When the upper mold moves to the top, the blocking assembly unlocks. Insert plate two pushes insert plate one to slide horizontally in sleeve one. After insert plate one has completely passed through, it resets. This achieves synchronous linkage for limiting during the pressing down of the upper mold. During the reset process, the ejection and support of the product are completed in sequence, allowing the product to leave the mold, reducing the difficulty of picking up and putting down, and improving production efficiency.

[0014] (2) The present invention proposes a stamping equipment for processing car headlight housings. It is equipped with two actuating plates, two rotating rollers, several push rods, a connecting plate, and two connecting plates. When the upper mold is pressed down, the insert plate moves down to contact and drive the actuating plate to rotate. After the insert plate passes through the actuating plate, it resets itself. When the cylinder drives the upper mold to move up and reset after stamping, the insert plate moves up synchronously and contacts the actuating plate again. At this time, the actuating plate cannot rotate due to the limit of the rotating roller. The upward pull of the insert plate drives the actuating plate to move up along the mounting groove, and then drives the connecting plate to move up through the connecting plate, pulling the push rod to extend and eject the formed product. As the upper mold continues to rise, the actuating plate drives the rotating roller to slide into the limit groove and can rotate. After the insert plate passes through the actuating plate, it resets itself, realizing the automatic ejection of the product after stamping and the automatic reset of the lifting structure.

Detailed Implementation

[0026] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0028] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0029] One preferred embodiment of this application, such as Figures 1 to 10As shown, a stamping equipment for processing vehicle headlight housings includes: a mounting housing 1, and further includes: a support plate 9, a housing 10, a cylinder 11, an upper die 12, a lower die 13, a limiting component, a lifting component, a support component, and a linkage mechanism; the support plate 9 is horizontally fixedly installed between the bottom inner walls of both sides of the mounting housing 1; the housing 10 is fixedly installed on the top of the support plate 9; the cylinder 11 is vertically fixedly installed at the center of the top inner wall of the housing 10; the upper die 12 is horizontally fixedly installed at the bottom of the cylinder 11; a mounting groove is opened on the top of the support plate 9, and the lower die 13 is fixedly installed on the bottom inner wall of the mounting groove, and the lower die 13 and the upper die 12 are used in corresponding cooperation; there are two sets of limiting components, which are respectively set on the inner walls of both sides of the housing 10; the lifting component is set directly below the support plate 9; there are two sets of support components, which are respectively set on the bottom inner walls of both sides of the housing 10; there are two sets of linkage mechanisms, which are respectively installed on both sides of the top of the upper die 12.

[0030] First, place the metal sheet to be processed stably on the support plate 9 at a suitable position directly above the lower mold 13, ensuring that the sheet is initially aligned with the processing area inside the mounting housing 1. Then, start the equipment. The cylinder 11 will drive the upper mold 12 to move vertically downwards, slowly approaching the lower mold 13. During the downward pressing of the upper mold 12, it will simultaneously drive the two sets of linkage mechanisms on its top sides. These two sets of linkage mechanisms will drive the two sets of limiting components to move, allowing the limiting components to contact the support plate 9 first and tightly press the edge of the metal sheet. In this way, the limiting components can accurately limit and fix the sheet, preventing the sheet from shaking or shifting position during stamping. After the upper mold 12 is completely pressed against the lower mold 13, the two will work together to stamp the metal sheet, pressing it into the shape of the headlight housing. After stamping, the cylinder 11 will drive the upper mold 12 to move upwards and reset. During this reset process, the upper mold 12 will be driven by the two sets of linkage mechanisms on the top to simultaneously drive the two sets of limiting components on its top sides to move downwards. The lifting component directly below the support plate 9 moves upward, exerting upward force to push the formed headlight housing product out of the cavity of the lower mold 13. When the product is almost at its highest position and completely detached from the lower mold 13, the linkage mechanism drives the two sets of support components to open. Then, the linkage mechanism releases the drive on the lifting component, and the lifting component begins to reset and fall back down. The product will then fall steadily onto the opened support components. At this time, the support components will support the product, keeping it suspended in the air. It is supported only by the contact points of the support components, completely detached from the upper mold 12 and the lower mold 13. Finally, the product can be easily removed from the support components. The entire stamping process of the headlight housing is thus completed. The whole process achieves the following: when the upper mold 12 presses down, the linkage mechanism synchronously drives the limiting component to limit the position. When resetting, the linkage mechanism sequentially completes the actions of the lifting component pushing out the product and the support components opening to support the product, allowing the product to completely detach from the mold and be suspended in the air. This greatly reduces the difficulty of picking up and putting down the product and improves production efficiency.

[0031] Further reference Figure 2 , Figures 5-7 and Figure 10The linkage mechanism includes: sleeve 1 201, insert plate 1 202, sleeve 2 203, insert plate 2 204, stop block 205, buffer spring 1 206, and blocking assembly. Two sleeves 1 201 are horizontally positioned directly above the top of the upper mold 12 on both sides. Two insert plates 1 202 are inserted into the two upper molds 12. Mounting grooves 2 are provided on the inner walls of both sides of the housing 10. The outer walls of both ends of the two sleeves 2 203 are slidably mounted to the inner walls of the two mounting grooves 2 via sliding assembly 1. One side of each insert plate 2 204 is inserted into one side of each sleeve 2 203. One side of the stop block 205 is inserted into the other side of the two sleeves 203 respectively. The edges between the top and bottom of the other side of the stop block 205 are all smooth curved surfaces. The two buffer springs 206 are fixedly installed between the two insert plates 204 and the two stop blocks 205 respectively. The middle position of the inner wall of the two mounting grooves 207 on the side away from each other is provided with a limiting groove 207. The edges between the sides of the inner walls of the two limiting grooves 207 that are close to each other and the sides of the two mounting grooves 207 that are away from each other are all smooth curved surfaces. The two blocking components are installed on both sides of the top of the upper mold 12 respectively.

[0032] When the equipment is not started, the two sleeves 201 are horizontally fixed above the top of the upper mold 12 on both sides. The insert plates 202 are inserted into the sleeves 201 and are restricted from moving horizontally by the blocking assembly. At this time, the stop block 205 is in close contact with the inner wall of the mounting groove 2, the buffer spring 206 is compressed to its maximum extent, and the insert plate 204 only partially protrudes from the sleeve 203. After the equipment is started, the cylinder 11 drives the upper mold 12 to move vertically downward, and simultaneously drives the sleeves 201, insert plates 202 and blocking assembly to move downward. After the bottom of the insert plate 202 contacts the top of the insert plate 204, due to the limitation of the stop block 205 and the inability of the buffer spring 206 to compress further, the insert plate 202... 02 drives the second insert plate 204, the second sleeve 203, and the stop block 205 to slide vertically down the second mounting groove. When the stop block 205 moves to the position of the first limiting groove 207, it slides into the groove along the smooth curved surfaces of both. The compression degree of the first buffer spring 206 decreases, and the stop block 205 is pressed against the inner wall of the first limiting groove 207. The vertical movement of the second sleeve 203 and the second insert plate 204 is restricted. The upper mold 12 continues to move down, and the first insert plate 202 pushes the second insert plate 204 to move towards the stop block 205 in the second sleeve 203 through the curved contact surface, and compresses the first buffer spring 206 again. After the first insert plate 202 has completely passed the second insert plate 204, the second insert plate 204 is compressed by the action of the first buffer spring 206. After the lower horizontal reset, the linkage mechanism drives the limiting component to complete the metal plate limiting and keep it stationary. Then, the cylinder 11 continues to drive the upper mold 12 to move down until it is completely in contact with the lower mold 13, completing the stamping of the headlight housing. After stamping, the cylinder 11 drives the upper mold 12 to reset upward, simultaneously driving the sleeve 1 201, insert plate 1 202 and the guard assembly to move upward. At the same time, the linkage mechanism drives the lifting component to eject the formed product. After the top of insert plate 1 202 contacts the bottom of insert plate 2 204 again, the non-curved surface of the contact side causes insert plate 2 204 to be unable to move horizontally, thus driving insert plate 2 204, sleeve 2 203 and stop block 205 to slide vertically upward along the mounting groove 2. The stop block 205 follows the... The locating groove 207 slides out smoothly and re-engages tightly with the inner wall of the mounting groove 2. The buffer spring 206 is compressed to its maximum extent again. During this process, the blocking assembly always restricts the horizontal movement of the insert plate 202. When the upper mold 12 moves to the top, the blocking assembly opens and unlocks. The insert plate 204 pushes the insert plate 202 to slide horizontally within the sleeve 201. After the insert plate 202 has completely passed through the insert plate 204, the insert plate 202 is horizontally reset under the action of its own reset structure. The insert plate 204 also returns to its initial state. The stop block 205 remains in contact with the inner wall of the mounting groove 2 and the buffer spring 206 is in its initial state of maximum compression, preparing for the next stamping operation.

[0033] Further reference Figure 2 , Figure 3 and Figure 8The limiting assembly includes: two mounting plates 301, two sleeves 302, two insert rods 303, two buffer springs 304, and two limiting blocks 305. The two mounting plates 301 are horizontally fixed to the outer walls of both ends of one of the sleeves 203. The two sleeves 302 are vertically fixed to the ends of the two mounting plates 301 that are far apart from each other. The two insert rods 303 are vertically inserted into the two sleeves 302. The two buffer springs 304 are fixedly installed between the top of the two insert rods 303 and the inner wall of the top of the two sleeves 302. The two limiting blocks 305 are fixedly installed at the bottom of the two insert rods 303.

[0034] When sleeve 203 moves vertically downward under the action of the linkage mechanism, it will simultaneously drive sleeve 302, insert rod 303, buffer spring 204, and limit block 1 305 to move vertically downward as a whole via mounting plate 1 301. As the downward movement progresses, limit block 1 305 first contacts the bearing plate 9. As sleeve 203 continues to move downward, insert rod 303, supported by the bearing plate 9, slides upward relative to sleeve 302, simultaneously compressing buffer spring 204 until buffer spring 204 is fully compressed, and limit block 1 305 is tightened. Pressed tightly onto the support plate 9, the metal plate is fixed in place. After stamping, when the sleeve 203 moves vertically upward under the drive of the linkage mechanism, the mounting plate 301 will simultaneously drive the limiting assembly to move upward as a whole. The supporting force on the insert rod 303 disappears, and the buffer spring 204 gradually rebounds and resets, pushing the insert rod 303 to slide downward relative to the sleeve 302. The limiting block 305 separates from the support plate 9 and finally returns to its initial position with the sleeve 203. The limiting assembly returns to its initial state, ready for the next operation.

[0035] Further reference Figure 3 and Figure 6The lifting assembly includes: two actuating plates 401, two rotating rollers 402, several push rods 403, a connecting plate 404, and two connecting plates 405. The two actuating plates 401 are slidably mounted on the inner walls of the two mounting slots via the sliding assembly 405. The sides of the two actuating plates 401 that are close to each other are inclined downwards. The two rotating rollers 402 are rotatably mounted on the sides of the two actuating plates 401 that are far apart from each other. Several push rods 403 are inserted into the lower mold 13. The connecting plate 404 is horizontally positioned directly below the bearing plate 9. The bottom of the top rod 403 passes through the support plate 9 and is fixedly installed on the top of the connecting plate 404. The connecting plate 405 is vertically set. The bottoms of the two connecting plates 405 are fixedly installed on both sides of the top of the connecting plate 404. The tops of the two connecting plates 405 pass through both sides of the top of the support plate 9 and are slidably installed between the inner walls of the two mounting grooves 2 through the sliding component 2. The inner walls of the two mounting grooves 2 on the side away from each other are provided with limiting grooves 2 406. The edges between the bottom inner walls of the two limiting grooves 2 406 and the mounting grooves 2 are all set with smooth curved surfaces.

[0036] Several buffer springs are fixedly installed between the bearing plate 9 and the connecting plate 404. During the pressing process of the upper mold 12, the insert plate 202 at its top moves downward and contacts the actuating plate 401, causing the actuating plate 401 to rotate around the contact point. After the insert plate 202 has completely passed the actuating plate 401, the actuating plate 401 returns to its initial tilted downward state under its own restoring force. After the stamping is completed, the cylinder 11 drives the upper mold 12 to reset upward, and the insert plate 202 moves upward synchronously and contacts the actuating plate again. At point 401 contact, the actuating plate 401 is limited because the rotating roller 402 is in close contact with the inner wall of the mounting groove 2, and cannot meet the space distance required for rotation, so it cannot rotate. The upward pulling force of the insert plate 202 drives the actuating plate 401 to move vertically upward along the mounting groove 2. When the actuating plate 401 moves upward, it drives the connecting plate 1 404 to move upward synchronously through the connecting plate 2 404, thereby pulling several push rods 403 to extend upward. The top of the push rods 403 lifts the product formed in the lower mold 13, while the bearing plate 9... The buffer spring 5 between the connecting plate 1 and 404 is compressed, which buffers the impact force of the lifting. As the upper mold 12 continues to rise, the actuating plate 401 drives the rotating roller 1 402 to move to the position of the limiting groove 2 406. The rotating roller 1 402 slides into the limiting groove 2 406 along the smooth curved surface between the bottom of the limiting groove 2 406 and the mounting groove 2. At this time, the depth provided by the limiting groove 2 406 meets the rotation requirements of the actuating plate 401. The insert plate 1 202 continues to move upward, driving the actuating plate 401 to rotate around the rotating roller. When 402 rotates, after the insert plate 202 has completely passed the actuating plate 401, the actuating plate 401 returns to its initial tilted downward state. Then, the buffer spring 5 returns to its original position, pushing the connecting plate 404 and the connecting plate 205 downward, which in turn drives the actuating plate 401 and the rotating roller 402 to return to their original positions simultaneously. The rotating roller 402 slides out of the limiting groove 206 and returns to the inner wall of the mounting groove 2. The push rod 403 also retracts into the lower mold 13, lifting the component back to its initial state, preparing for the next operation.

[0037] Further reference Figure 2 , Figure 3 , Figure 6 , Figure 9 as well as Figure 10 The support assembly includes: two insert blocks 501, two support plates 502, two buffer springs 503, and two limiting blocks 504. Slots 1 are provided at both ends of the bottom inner wall of one side of the housing 10. The two insert blocks 501 are respectively inserted into the two slots 1. The edges of the top side of the insert blocks 501 are all set with smooth curved surfaces. The two support plates 502 are respectively horizontally fixedly installed at the bottom of the two insert blocks 501. The two buffer springs 503 are respectively fixedly installed between the other side of the two insert blocks 501 and the inner wall of one side of the two slots 1. The two limiting blocks 204 are respectively set at both ends of one of the sleeves 201.

[0038] Cylinder 11 drives the upper mold 12 to move vertically downwards, simultaneously driving sleeve 201 and the limiting blocks 504 at both ends to move downwards as well. When the limiting blocks 504 move to contact the smooth curved surface at the top of the insert 501, the upper mold 12 continues to move downwards. The limiting blocks 504 generate a horizontal pushing force on the insert 501, pushing the insert 501 to move horizontally inwards along slot 1, simultaneously compressing the buffer spring 503. Since the horizontal change distance between the insert 501 and the support plate 502 is small, only slight movement is needed to allow the support plate 502 to completely retract into slot 1, avoiding the stamping area of ​​the lower mold 13 and preventing interference with the stamping and forming of the metal sheet. During this process, the vertical change of the insert 501 and the support plate 502 is small. After stamping is completed, cylinder 11 drives upper mold 12 to reset upward, simultaneously driving sleeve 201 and limit block 504 to move upward. When limit block 504 and insert block 501 are completely separated, buffer spring 3 503 loses pressure and rebounds quickly, pushing insert block 501 to reset horizontally outward along slot 1. Support plate 502 extends out of slot 1 at the same time. At this time, the lifting component has lifted the formed product away from lower mold 13. The extended support plate 502 just supports the product below, realizing product suspension support, which is convenient for removal. After the product is removed, the support component keeps insert block 501 and support plate 502 in the extended state until the next time upper mold 12 is pressed down, repeating the above retraction action to complete the cycle operation.

[0039] Further reference Figure 5 and Figure 6 The sliding assembly includes: a slide rail 601 and a slider 602. The two slide rails 601 are vertically fixed to the inner walls of both ends of one of the mounting grooves 2. The two sliders 602 are slidably installed on the two slide rails 601. The two sliders 602 are fixedly installed to the outer walls of both ends of the corresponding sleeves 203. The sliding assembly 2 includes: a slider 603. The two sliders 603 are slidably installed on the two slide rails 601. The ends of the two sliders 603 that are close to each other are rotatably installed to the two ends of the corresponding toggle plate 401 through a torsion spring shaft.

[0040] Sleeve 203, driven by insert plate 202, needs to move vertically downward along mounting groove 2. At this time, slider 602, which is fixed to sleeve 203, will slide steadily downward along slide rail 601, providing guidance and support for the downward movement of sleeve 203 and ensuring that sleeve 203 moves smoothly without deviation. At the same time, the linkage mechanism drives the actuating plate 401 to move downward synchronously. Slide 603, which is rotatably connected to the actuating plate 401, will slide downward synchronously along slide rail 601. With the guidance of slide rail 601, the actuating plate 401 is kept stable during downward movement and does not tilt. After stamping is completed, upper mold 12 is reset. The linkage mechanism moves upward, causing sleeve 203 to move upward as well. This causes slider 602 to slide steadily upward along slide rail 601. The actuating plate 401 resets upward under the action of the linkage mechanism, and slider 203 also slides upward along slide rail 601 until slider 102 and slider 203 return to their initial positions at the top of slide rail 601, preparing for the next operation. Throughout the process, sleeve 203 slides smoothly on slide rail 601 via slider 102, and actuating plate 401 slides steadily on slide rail 601 via slider 203, ensuring precise and smooth linkage action.

[0041] Further reference Figure 2 and Figure 3 The top outer wall of sleeve 203 is vertically fixed to the mounting rod 701. The tops of both sides of the mounting rod 701 are fixed to the connecting rod 702. The ends of the two connecting rods 702 that are far apart from each other are fixed to the top outer walls of the two sleeves 302 that are close to each other.

[0042] This rigid connection between sleeve 203 and sleeve 302 via mounting rod 701 and connecting rod 702 allows sleeve 203 and sleeve 302 to form an integrated linkage structure. When sleeve 203 moves down or up, it can directly, synchronously and precisely drive sleeve 302 to move, avoiding delays or misalignments between the two. This ensures that the limiting component can accurately follow the rhythm of the linkage mechanism to complete the action of pressing the plate and separating from the bearing plate 9. At the same time, the rigid connection structure allows the downward pressure transmitted by sleeve 203 to act directly and evenly on both sides of the top of sleeve 302, avoiding the tilting of sleeve 302 caused by uneven force on one side.

[0043] Further reference Figures 2-4 and Figure 10The blocking assembly includes: mounting plate 2 801, baffle 1 802, baffle 2 803, rotating roller 2 804, mounting bracket 805, two limiting rods 806, and two buffer springs 4 807. The two mounting plates 2 801 are horizontally fixedly installed on both sides of the top of the upper mold 12. The top of mounting plate 2 801 is fixedly installed to the bottom outer wall of the corresponding sleeve 1 201. Both ends of one side of mounting plate 2 801 are fixedly installed to two limiting blocks 2 504. A slot 2 is provided in the middle of the top of mounting plate 2 801. A baffle 802 is inserted into slot 2. One buffer spring 807 is fixedly installed between the bottom of baffle 802 and slot 2. One side of baffle 2 803 is inserted into sleeve 201. Another buffer spring 807 is fixedly installed between one side of baffle 2 803 and insert plate 202. Rotating roller 2 804 is rotatably installed on the other side of baffle 2 803. Mounting bracket 805 is horizontally fixed between the inner walls of both sides of box 10. Two limiting rods 806 are vertically fixed at both ends of the bottom side of mounting bracket 805.

[0044] Another buffer spring 807 between one side of baffle 2 803 and insert 1 202 is in its maximum compression state. The rotating roller 804 rotatably mounted on the other side of baffle 2 803 is in contact with the inclined / curved surface of baffle 1 802. Baffle 2 803 forms a limit on baffle 2. The mounting bracket 805 is horizontally fixed between the inner walls of the two sides of the box 10. The limiting rod 806, which is vertically fixed at both ends on the bottom side, is directly opposite the top two sides of baffle 1 802. At the same time, the inner wall of the mounting groove 2 is provided with a friction element, which is sleeve 20. 3. Provides lateral friction to prevent it from falling under its own weight when there is no structural support. The upper mold 12 presses down, driving the mounting plate 2 801, sleeve 1 201 and other blocking components to move down as a whole. During this process, the rotating roller 2 804 is always in contact with the baffle 1 802, the buffer spring 4 807 is kept in the maximum compression state, and the baffle 2 803 restricts the horizontal movement of the insert plate 1 202 in the sleeve 1 201, ensuring that the insert plate 1 202 can stably drive the linkage mechanism to move. After the stamping is completed, the upper mold 12 resets upward, driving the blocking mechanism to move downward. The entire baffle assembly moves upward. When the top two sides of the baffle 802 contact the limiting rod 806, the upper mold 12 continues to move upward. The limiting rod 806 exerts downward pressure on the baffle 802, pushing the baffle 802 downward along the slot 2, compressing the buffer spring 807 at its bottom. As the baffle 802 moves downward, the contact surface position between it and the rotating roller 804 changes. The rotating roller 804 rolls along the inclined / curved contact surface and generates lateral displacement, driving the baffle 803 in the sleeve 20. 1. The plate moves laterally within the mold. At this time, the compression of the buffer spring 807 between the second baffle 803 and the first insert 202 decreases, releasing the horizontal limit on the first insert 202. Subsequently, the first insert 202 continues to move upward with the upper mold 12 and comes into contact with the second insert 204. Since the buffer spring 807 has been relaxed, the first insert 202 can move horizontally within the sleeve 201. When the first insert 202 has completely passed the second insert 204, it returns to its horizontal position under the slight action of its own reset structure and the buffer spring 807.

[0045] Working principle: First, place the metal sheet to be processed stably in a suitable position directly above the corresponding lower mold 13, ensuring that the sheet is initially aligned with the processing area. Then, start the equipment. Cylinder 11 drives the upper mold 12 to move vertically downward, simultaneously moving sleeve 1 201, insert plate 1 202, and the blocking assembly downward. After the bottom of insert plate 1 202 contacts the top of insert plate 2 204, insert plate 2 204, sleeve 2 203, and stop block 205 slide vertically down along the mounting groove 2. Sleeve 2 203 simultaneously moves sleeve 3 302, insert rod 303, buffer spring 2 304, and limit block 1 305 downward as a whole. Limit block 1 305 first contacts the bearing plate 9. Sleeve 2 203 continues to move downward, and insert rod 303 slides upward relative to sleeve 3 302. The compression buffer spring 304 is compressed until the limiting block 305 is tightly pressed onto the bearing plate 9 to complete the limiting and fixing of the metal plate. At the same time, during the downward pressing of the upper mold 12, the insert plate 202 moves downward and contacts the actuating plate 401, causing it to rotate. After the insert plate 202 has completely passed through, the actuating plate 401 returns to its initial tilted downward state, and the sleeve 201 and the limiting blocks 504 at both ends move downward with the upper mold 12. After the limiting blocks 504 contact the top of the insert 501, they push the insert 501 to move inward along the slot 1, compressing the buffer spring 303, so that the support plate 502 is completely retracted into the slot 1 to avoid the stamping area. When the stop block 205 moves to the position of the limiting groove 207, it slides into the groove along the smooth curved surface. The buffer spring 204 is compressed. 6. As the compression decreases and the stop 205 is pressed against, the vertical movement of sleeve 203 and insert plate 204 is restricted. The upper mold 12 continues to move downward. Insert plate 1 202 pushes insert plate 204 to move towards the stop 205 within sleeve 203 and compresses buffer spring 1 206 again. After insert plate 1 202 has completely passed through, insert plate 204 returns to its horizontal position. Subsequently, cylinder 11 continues to drive the upper mold 12 to move downward until it is fully in contact with the lower mold 13, completing the stamping of the headlight housing. After stamping, cylinder 11 drives the upper mold 12 to return to its upward position, simultaneously driving sleeve 1 201, insert plate 1 202, and the guard assembly to move upward. The linkage mechanism drives the lifting assembly to eject the formed product. After the top of insert plate 1 202 contacts the bottom of insert plate 204 again, it drives... Insert plate 204, sleeve 203, and stop block 205 slide vertically upwards along mounting groove 2. Stop block 205 slides out of limiting groove 1 207 and re-engages tightly with the inner wall of mounting groove 2. Buffer spring 1 206 is compressed to its maximum extent again. Sleeve 203 simultaneously drives the limiting assembly to move upwards as a whole. The supporting force on insert rod 303 disappears, buffer spring 2 304 rebounds and resets, insert rod 303 slides downwards relative to the limit block 1 305, separates from bearing plate 9, insert plate 1 202 moves upwards and re-engages with actuating plate 401, driving actuating plate 401 to move vertically upwards along mounting groove 2. Actuating plate 401 drives connecting plate 1 404 to move upwards through connecting plate 2 405, thereby pulling push rod 403 upwards to eject the molded product from lower mold 13.The buffer spring 5 between the bearing plate 9 and the connecting plate 404 is compressed to provide cushioning. As the upper mold 12 continues to rise, the actuating plate 401 drives the rotating roller 402 to move to the position of the limiting groove 406 and slide into the groove. The insert plate 202 continues to move upward, driving the actuating plate 401 to rotate. After the insert plate 202 has completely passed through, the actuating plate 401 returns to its initial state. Then, the buffer spring 5 rebounds and resets, driving the connecting plate 404, connecting plate 405, actuating plate 401, and rotating roller 402 to reset downward. The push rod 403 retracts into the lower mold 13. As the upper mold 12 moves upward, sleeve 1 201 and limiting block 2 504 move upward. After limiting block 2 504 completely separates from insert block 501, buffer spring 3 503 rebounds and pushes insert block 501 outward. Support plate 502 extends simultaneously to support the product that has been pushed off the lower mold 13, achieving product suspension support for easy removal. When the upper mold 12 moves to its highest position, the top two sides of baffle 1 802 contact limiting rod 806. The upper mold 12 continues to move upward, pushing baffle 1 802 downward and compressing buffer spring 4 807 at its bottom. After baffle 1 802 moves downward, rotating roller 2 80... 4. Lateral displacement is generated, causing baffle 2 803 to move laterally within sleeve 1 201. The compression of buffer spring 4 807 between baffle 2 803 and insert plate 1 202 decreases, releasing the horizontal limit on insert plate 1 202. Subsequently, insert plate 1 202 continues to move upward with upper mold 12 and contacts insert plate 2 204, allowing it to move horizontally within sleeve 1 201. After insert plate 1 202 completely passes through insert plate 2 204, it horizontally resets under the action of its own reset structure and buffer spring 4 807. Finally, upper mold 12 causes the entire blocking assembly to move downward a short distance, and baffle 1 802 and the limit... When the positioning rod 806 separates, the buffer spring 807 at its bottom rebounds, pushing the baffle 802 upwards to reset. After the rotating roller 804 loses pressure, the baffle 803 resets laterally, and the rotating roller 804 re-adheres with the baffle 802. The limiting component returns to its initial position along with the sleeve 203. All components return to their initial state, facilitating product removal and preparing for the next stamping operation. This achieves synchronous linkage for limiting during the downward pressing of the upper mold 12, and sequentially completes the ejection and support of the product during the reset process, allowing the product to detach from the mold, reducing the difficulty of handling and improving production efficiency.
