Description

Technical Field

[0001] The present invention relates to the technical field of hot plate welding, and specifically to a trajectory hot plate welding device. Background Art

[0002] With the development of technology, traditional pneumatic hot plate machines cannot meet market requirements. The precise movement of a pneumatic hot plate machine to a certain position can only be ensured through hard limits. However, current technology requires the device to accurately stop at multiple positions during operation to avoid the interference area of the hot mold, ensuring that all components of the pneumatic hot plate machine do not collide with each other during operation, thereby protecting the device from damage. However, the current solution on the market is to use servo control to replace the existing pneumatic control, resulting in the inability to continue using the original pneumatic components, which brings cost pressure and the problem of stagnant pneumatic equipment.

[0003] During the hot plate welding process, it is necessary to first melt the welding surface of the workpiece on the hot mold. During the process of melting the workpiece by the hot mold, some of the melted materials on the welding surface of the workpiece will adhere to the hot mold. As a result, during the next welding, the workpiece materials adhering to the hot mold will affect the contact area between the heating mold and the workpiece, resulting in the inability of the welding surface of the workpiece to fit with the hot mold. Furthermore, the heat on the hot mold cannot be evenly transferred to the welding surface of the workpiece, which may cause local overheating of the welding surface of the workpiece, affecting the welding quality. After welding, the temperature of the welded part of the workpiece may be too high, and directly taking out the workpiece easily causes the workpiece to deform. Existing hot plate machines mostly use air cooling for cooling, but the cooling speed cannot be adjusted according to the temperature of the welding part, which may lead to defects such as cracks in the welding part, affecting the welding quality. And natural cooling takes too long, increasing the time of the entire welding process and resulting in a decrease in production efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a trajectory hot plate welding device to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A trajectory hot plate welding device, the welding device includes a frame, a hot mold mechanism, a template mechanism, a lifting mechanism, a cooling mechanism, and a cleaning mechanism. The frame is fixedly connected to the hot mold mechanism. There are two template mechanisms, and the two template mechanisms are slidably connected to the hot mold mechanism. There are two lifting mechanisms, and the two template mechanisms are respectively fixedly connected to the two lifting mechanisms. The two lifting mechanisms are fixedly connected to the frame. The cooling mechanism is fixedly connected to the frame. There are two cleaning mechanisms, and the two cleaning mechanisms are fixedly connected to the frame.

[0007] Through two lifting mechanisms fixed on the frame, the two template mechanisms are fixedly connected to the two lifting mechanisms respectively, so that the two template mechanisms are moved toward the hot mold mechanism, and then the workpieces to be welded fixed on the two template mechanisms are aligned with the hot mold mechanism, and the lifting mechanism continuously applies pressure to melt the workpieces to be welded, and the lifting mechanism is used to make the template mechanism and the workpiece to be welded withdraw from the hot mold mechanism, and the hot mold mechanism moves backward. The lifting mechanism drives the two template mechanisms to move relatively, so that the workpieces are welded, and the cooling mechanism cools the welded workpiece to make it cool quickly, and the cleaning mechanism is used to clean the material of the molten workpiece attached to the hot mold mechanism.

[0008] Furthermore, the thermal mold mechanism includes a thermal mold, a lower thermal mold, an upper thermal mold, a track plate, a No. 1 linear module and a No. 1 linear guide rail. The thermal mold and the lower thermal mold are fixedly connected, the upper thermal mold and the thermal mold are fixedly connected, the track plate and the thermal mold are fixedly connected, the sliding end of the No. 1 linear module and the thermal mold are fixedly connected, the No. 1 linear module and the frame are fixedly connected, the sliding end of the No. 1 linear guide rail and the thermal mold are fixedly connected, and the No. 1 linear guide rail and the frame are fixedly connected.

[0009] The hot template is fixedly connected to the lower hot mold and the upper hot mold, so that the hot template provides a stable structural support for the lower hot mold and the upper hot mold, ensuring that no displacement or shaking occurs during the welding process, which is beneficial to ensuring the accuracy and consistency of welding. Through the provided track plate, the template mechanism moves along the track set on the track plate when rising, and the lower hot mold and the upper hot mold respectively contact the welding surfaces of the two workpieces to be welded, so as to melt the welding surfaces of the workpieces. After the welding surfaces of the workpieces are melted, the workpieces are separated from the lower hot mold and the upper hot mold through the lifting mechanism, and the No. 1 linear module and the No. 1 linear guide cooperate to drive the No. 1 linear module to move, so that the hot template drives the lower hot mold and the upper hot mold to move backward.

[0010] Furthermore, the template mechanism includes template No. 1, linear guide No. 2, template No. 2, support seat and bearing. Template No. 1 is fixedly connected to linear guide No. 2, the sliding end of linear guide No. 2 is fixedly connected to template No. 2, the support seat is fixedly connected to template No. 2, the bearing is fixedly connected to the support seat, and the bearing is slidably connected to the track plate.

[0011] The bearing and the track plate are slidably connected to guide the upward motion trajectory of the bearing, and the sliding end of the No. 2 linear guide rail is fixedly connected to the No. 2 template so that the No. 2 template can move left and right relative to the No. 1 template. The bearing and the support seat are fixed, and the support seat and the No. 2 template are fixed. When the rising direction of the bearing changes, the support seat drives the No. 2 template to move left or right along with the direction of the bearing change.

[0012] Further, the track plate is provided with a third sliding groove which is slidably connected to the bearing. The third sliding groove is provided with a first inclined surface, and the included angle between the first inclined surface and the bottom surface of the second template is an acute angle. The third sliding groove is also provided with a second inclined surface, and the included angle between the second inclined surface and the bottom surface of the second template is an obtuse angle.

[0013] When the first template rises, the bearing enters the third sliding groove and rises linearly along the third sliding groove. When the bearing enters the first inclined surface, the linear upward movement of the bearing changes to an inclined upward movement to the left, causing the second template to move leftward to avoid the interference area of the hot mold. The first template continues to rise. When the bearing enters the second inclined surface, the linear upward movement of the bearing changes to an inclined upward movement to the right, and the second template moves rightward accordingly, aligning the workpiece with the hot mold.

[0014] Further, the cooling mechanism includes a cooling fan, a baffle, a connecting plate, a return spring and a bimetallic strip. The cooling fan is fixedly connected to the frame. The hot template is provided with a cooling channel, and the cooling fan is connected to the cooling channel through a pipeline. The hot template is provided with a first sliding groove, and the baffle is arranged in the first sliding groove. The hot template is provided with a mounting groove, and the connecting plate is arranged in the mounting groove. The connecting plate is fixedly connected to the baffle. The return spring is arranged in the mounting groove and fixedly connected to the connecting plate. The bimetallic strip abuts against the connecting plate.

[0015] By connecting the cooling fan and the cooling channel through a pipeline, the air flow generated when the cooling fan operates is introduced into the cooling channel through the pipeline connection. When the bimetallic strip approaches the welded workpiece, the bimetallic strip will bend and deform when heated, pushing the connecting plate to move in the mounting groove, and the baffle fixedly connected to it will move synchronously in the first sliding groove, thereby reducing the ventilation cross-sectional area of the cooling channel, increasing the wind speed, and enhancing the cooling effect. When the temperature of the workpiece drops, the bimetallic strip gradually returns to its original state, reducing the thrust on the connecting plate. The connecting plate and the baffle are pushed back to their original positions by the return spring, increasing the ventilation cross-sectional area of the cooling channel, and thus cooling the workpiece evenly.

[0016] Further, the cleaning mechanism includes a bracket, a scraper, a second linear module, a third linear guide rail, a fixing plate, an elastic unit and an adjusting unit. The bracket is slidably connected to the scraper. The sliding end of the second linear module is fixedly connected to the bracket. The second linear module is fixedly connected to the fixing plate, and the fixing plate is fixedly connected to the frame. The second linear module is also fixedly connected to the frame. The sliding end of the third linear guide rail is fixedly connected to the bracket. The third linear guide rail is fixedly connected to the fixing plate and the frame. The elastic unit is fixedly connected to the frame and abuts against the scraper. The adjusting unit is slidably connected to the scraper.

[0017] The second linear module fixed to the frame drives the bracket fixedly connected to its sliding end, enabling the bracket to move smoothly under the guiding action of the third linear guide rail. Since the bracket is slidably connected to the scraper, the scraper is driven to move towards the hot mold. The elastic unit fixedly connected to the frame abuts against the scraper. The groove on the bracket and the small cylindrical block on the scraper are slidably connected, enabling the scraper to slide or rotate along the bracket. Thus, during the movement of the scraper, it can adaptively slide into the bracket according to the contact position with the hot mold and always maintain good contact with the hot mold to ensure the cleaning effect on the surface of the hot mold. Through the adjusting unit slidably connected to the scraper, the adjusting unit contacts the positioning block on the hot mold. According to the position and shape of the positioning block, etc., the angle of the scraper is automatically adjusted so that the scraper can clean the hot mold at the best angle, avoiding cleaning dead corners and effectively removing impurities such as molten materials attached to the hot mold.

[0018] Further, the elastic unit includes a first sliding rod, a sleeve, and a compression spring. The first sliding rod is slidably connected to the sleeve, the sleeve is fixedly connected to the bracket, the compression spring is sleeved outside the first sliding rod, and the compression spring is fixedly connected to the sleeve.

[0019] Through the first sliding rod abutting against the scraper, and the first sliding rod being slidably connected to the sleeve, when the surface height of the scraper in contact with the hot mold changes, the first sliding rod slides into the sleeve, and then the scraper can slide into the bracket. One end of the compression spring sleeved outside the first sliding rod is fixedly connected to the sleeve, so that the sliding of the first sliding rod will compress the compression spring. Then, after the compression spring is compressed, it generates an elastic force, which is transmitted to the scraper through the first sliding rod, enabling the scraper to adapt to the height undulations of the hot mold surface and always maintain close contact with the hot mold, thereby maintaining a good contact state between the scraper and the hot mold and ensuring the cleaning effect on the hot mold.

[0020] Further, the adjusting unit includes a slider, an adjusting plate, and a rotating rod. The scraper is provided with a second sliding groove. The slider is slidably connected to the second sliding groove. The slider abuts against the adjusting plate. The adjusting plate is fixedly connected to the rotating rod, and the rotating rod is rotatably connected to the scraper.

[0021] Through the slider, when the scraper moves with the bracket, the slider moves in the opposite direction when encountering an obstacle. Through the slider abutting against the adjusting plate, the adjusting plate being fixed to the rotating rod, and the rotating rod being rotatably connected to the scraper, the adjusting plate rotates along the rotating rod, thereby pushing the scraper to rotate, so as to adjust the angle of the scraper.

[0022] Further, the lifting mechanism includes a cylinder, a second sliding rod, and a slide rail. The cylinder is fixedly connected to the frame, the slide rail is fixedly connected to the frame, the second sliding rod is slidably connected to the slide rail, the output end of the cylinder is fixedly connected to the first template, and the second sliding rod is fixedly connected to the first template.

[0023] A driving force for linear motion is generated at the output end of the cylinder. The second slide bar is slidably connected to the slide rail to provide guiding for the first template, enabling it to slide linearly smoothly. Thus, the first template can move up or down along a predetermined linear trajectory to meet the requirements for adjusting the position of the first template by the welding device at different working stages.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. By slidably connecting the bearing and the track plate, the movement trajectory for guiding the bearing to rise is formed. Through the second linear guide rail fixed to the first template, the second template can move left and right relative to the first template. By fixing the bearing seat and the second template, the second template moves horizontally along with the bearing, thus avoiding the interference area of the hot mold. There is no need to use servo control to replace pneumatic control, reducing the cost of purchasing servo equipment and increasing the utilization rate of idle equipment.

[0026] 2. By bringing the bimetallic strip close to the welded workpiece, the bimetallic strip will bend and deform after being heated, pushing the connecting plate to move in the installation groove, causing the baffle plate to move synchronously. When the temperature drops, the bimetallic strip gradually returns to its original state, reducing the thrust on the connecting plate. The connecting plate and the baffle plate are pushed back by the return spring, thereby changing the cross-sectional area of the cooling channel, and then controlling the wind speed of the cooling channel, so as to adjust the cooling speed according to the temperature of the welding part and avoid defects such as cracks at the welding part.

[0027] 3. The second linear module drives the bracket, thereby driving the scraper to move towards the hot mold. The elastic unit abuts against the scraper, so that during the movement of the scraper, it can slide into the bracket adaptively according to the contact position with the hot mold and always maintain good contact with the hot mold, ensuring the cleaning effect on the surface of the hot mold. Through the adjustment unit, the scraper can automatically adjust the angle of the scraper according to the position and shape of the hot mold, etc., so that the scraper can clean the hot mold at the best angle, avoiding cleaning dead corners and effectively removing impurities such as molten materials attached to the hot mold.

[0039] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment: As Figure 1 - Figure 2As shown, the present invention provides a technical solution for a track hot plate welding device, a track hot plate welding device, the welding device includes a frame 1, a hot mold mechanism 2, a template mechanism 3, a lifting mechanism 4, a cooling mechanism 5 and a cleaning mechanism 6, the frame 1 is fixedly connected to the hot mold mechanism 2, two template mechanisms 3 are provided, the two template mechanisms 3 are slidably connected to the hot mold mechanism 2, the lifting mechanism 4 is provided with two, the two template mechanisms 3 are respectively fixedly connected to the two lifting mechanisms 4, the two lifting mechanisms 4 are fixedly connected to the frame 1, the cooling mechanism 5 is fixedly connected to the frame 1, and two cleaning mechanisms 6 are provided, and the two cleaning mechanisms 6 are fixedly connected to the frame 1.

[0041] Through two lifting mechanisms 4 fixed on the frame 1, the two template mechanisms 3 are fixedly connected to the two lifting mechanisms 4 respectively, so that the two template mechanisms 3 are moved toward the hot mold mechanism 2, and then the workpieces to be welded fixed on the two template mechanisms 3 are aligned with the hot mold mechanism 2, and the lifting mechanism 4 continuously applies pressure to melt the workpieces to be welded, and the template mechanism 3 and the workpiece to be welded are withdrawn from the hot mold mechanism 2 through the lifting mechanism 4, and the hot mold mechanism 2 moves backward. The lifting mechanism 4 drives the two template mechanisms 3 to move relatively, so that the workpieces are welded, and the cooling mechanism 5 cools the welded workpiece to make it cool quickly, and the cleaning mechanism 6 cleans the material of the molten workpiece attached to the hot mold mechanism 2.

[0042] like Figure 3 As shown, the thermal mold mechanism 2 includes a thermal mold 21, a lower thermal mold 22, an upper thermal mold 23, a track plate 24, a No. 1 linear mold 25 and a No. 1 linear guide rail 26. The thermal mold 21 is fixedly connected to the lower thermal mold 22, the upper thermal mold 23 is fixedly connected to the thermal mold 21, the track plate 24 is fixedly connected to the thermal mold 21, the sliding end of the No. 1 linear module 25 is fixedly connected to the thermal mold 21, the No. 1 linear module 25 is fixedly connected to the frame 1, the sliding end of the No. 1 linear guide rail 26 is fixedly connected to the thermal mold 21, and the No. 1 linear guide rail 26 is fixedly connected to the frame 1.

[0043] The hot template 21 is fixedly connected to the lower hot mold 22 and the upper hot mold 23, so that the hot template 21 provides a stable structural support for the lower hot mold 22 and the upper hot mold 23, ensuring that no displacement or shaking occurs during the welding process, which is beneficial to ensuring the accuracy and consistency of welding. Through the provided track plate 24, the template mechanism 3 moves along the track set by the track plate 24 when rising, and the lower hot mold 22 and the upper hot mold 23 are respectively in contact with the welding surfaces of the two workpieces to be welded, so as to melt the welding surfaces of the workpieces. After the welding surfaces of the workpieces are melted, the workpieces are separated from the lower hot mold 22 and the upper hot mold 23 by the lifting mechanism 4, and the No. 1 linear module 25 and the No. 1 linear guide rail 26 cooperate to drive the No. 1 linear module 25 to move the hot template 21, so that the hot template 21 drives the lower hot mold 22 and the upper hot mold 23 to move backward.

[0044] likeFigure 4 As shown in the figure, the template mechanism 3 includes a first template 31, a second linear guide 32, a second template 33, a support base 34, and a bearing 35. The first template 31 is fixedly connected to the second linear guide 32. The sliding end of the second linear guide 32 is fixedly connected to the second template 33. The support base 34 is fixedly connected to the second template 33. The bearing 35 is fixedly connected to the support base 34. The bearing 35 is slidably connected to the track plate 24.

[0045] By the sliding connection between the bearing 35 and the track plate 24, the movement trajectory of guiding the bearing 35 to rise is formed. By the fixed connection between the sliding end of the second linear guide 32 and the second template 33, the second template 33 can move left and right relative to the first template 31. By the fixation between the bearing 35 and the support base 34, and the fixation between the support base 34 and the second template 33, when the rising direction of the bearing 35 changes, the support base 34 drives the second template 33 to move left or right along with the changing direction of the bearing 35.

[0046] As Figure 5 shown in the figure, the track plate 24 is provided with a third sliding groove 241. The third sliding groove 241 is slidably connected to the bearing 35. The third sliding groove 241 is provided with a first inclined surface 2411. The included angle between the first inclined surface 2411 and the bottom surface of the second template 33 is an acute angle. The third sliding groove 241 is provided with a second inclined surface 2412. The included angle between the second inclined surface 2412 and the bottom surface of the second template 33 is an obtuse angle.

[0047] When the first template 31 rises, the bearing 35 enters the third sliding groove 241, and the bearing 35 rises linearly along the third sliding groove 241. When the bearing 35 enters the first inclined surface 2411, the bearing 35 changes from linear rising to rising obliquely to the left, causing the second template 33 to move leftward accordingly to avoid the interference area of the hot mold. The first template 31 continues to rise. When the bearing 35 enters the second inclined surface 2412, the bearing 35 changes from linear rising to rising obliquely to the right, and the second template 33 moves rightward accordingly to align the workpiece with the hot mold.

[0048] As Figure 2 and Figure 6 shown in the figure, the cooling mechanism 5 includes a cooling fan 51, a baffle 52, a connecting plate 53, a return spring 54, and a bimetallic strip 55. The cooling fan 51 is fixedly connected to the frame 1. The hot template 21 is provided with a cooling channel 211. The cooling fan 51 is connected to the cooling channel 211 through a pipeline. The hot template 21 is provided with a first sliding groove 212. The baffle 52 is arranged in the first sliding groove 212. The hot template 21 is provided with a mounting groove 213. The connecting plate 53 is arranged in the mounting groove 213. The connecting plate 53 is fixedly connected to the baffle 52. The return spring 54 is arranged in the mounting groove 213. The return spring 54 is fixedly connected to the connecting plate 53. The bimetallic strip 55 abuts against the connecting plate 53.

[0049] The cooling fan 51 is connected to the cooling channel 211 through a pipeline. When the cooling fan 51 operates, the airflow generated is introduced into the cooling channel 211 through the pipeline connection. The bimetallic strip 55 is close to the welded workpiece. After the bimetallic strip 55 is heated, it will bend and deform, pushing the connecting plate 53 to move in the installation groove 213. The baffle 52 fixedly connected thereto moves synchronously in the first sliding groove 212, so that the ventilation cross-sectional area of the cooling channel 211 becomes smaller, the wind speed is increased, and the cooling effect is enhanced. When the temperature of the workpiece drops, the bimetallic strip 55 gradually returns to its original state, the thrust on the connecting plate 53 is reduced, and the connecting plate 53 and the baffle 52 are pushed back by the return spring 54, so that the ventilation cross-sectional area of the cooling channel 211 becomes larger, and then the workpiece is cooled evenly.

[0050] As Figure 7 shown, the cleaning mechanism 6 includes a bracket 61, a scraper 62, a second linear module 63, a third linear guide rail 64, a fixing plate 65, an elastic unit 66 and an adjusting unit 67. The bracket 61 and the scraper 62 are slidably connected. The sliding end of the second linear module 63 is fixedly connected to the bracket 61. The second linear module 63 is fixedly connected to the fixing plate 65. The fixing plate 65 is fixedly connected to the frame 1. The second linear module 63 is fixedly connected to the frame 1. The sliding end of the third linear guide rail 64 is fixedly connected to the bracket 61. The third linear guide rail 64 is fixedly connected to the fixing plate 65. The third linear guide rail 64 is fixedly connected to the frame 1. The elastic unit 66 is fixedly connected to the frame 1. The elastic unit 66 abuts against the scraper 62. The adjusting unit 67 is slidably connected to the scraper 62.

[0051] The second linear module 63 fixed to the frame 1 drives the bracket 61 fixedly connected to its sliding end, so that the bracket 61 moves smoothly under the guiding action of the third linear guide rail 64. Since the bracket 61 is slidably connected to the scraper 62, the scraper 62 is driven to move towards the hot die. The elastic unit 66 fixedly connected to the frame 1 abuts against the scraper 62. The groove on the bracket 61 is slidably connected to the small cylindrical block on the scraper 62, so that the scraper 62 can slide or rotate along the bracket 61. Thus, during the movement of the scraper 62, it can slide into the bracket 61 adaptively according to the contact position with the hot die and always maintain good contact with the hot die to ensure the cleaning effect on the surface of the hot die. Through the adjusting unit 67 slidably connected to the scraper 62, the adjusting unit 67 contacts the positioning block on the hot die, and automatically adjusts the angle of the scraper 62 according to the position and shape of the positioning block, etc., so that the scraper 62 can clean the hot die at the best angle, avoid cleaning dead corners, and effectively remove impurities such as molten materials attached to the hot die.

[0052] As Figure 8 and Figure 9As shown, the elastic unit 66 includes a first sliding rod 661, a sleeve 662, and a compression spring 663. The first sliding rod 661 is slidably connected to the sleeve 662. The sleeve 662 is fixedly connected to the bracket 61. The compression spring 663 is sleeved outside the first sliding rod 661 and is fixedly connected to the sleeve 662.

[0053] Through the first sliding rod 661 that abuts against the scraper 62, and the first sliding rod 661 is slidably connected to the sleeve 662. When the height of the surface where the scraper 62 contacts the hot mold changes, the first sliding rod 661 slides into the sleeve 662, and then the scraper 62 can slide into the bracket 61. One end of the compression spring 663 sleeved outside the first sliding rod 661 is fixedly connected to the sleeve 662, so that the sliding of the first sliding rod 661 will compress the compression spring 663. Then, after the compression spring 663 is compressed, it generates an elastic force, which is transmitted to the scraper 62 through the first sliding rod 661, enabling the scraper 62 to adapt to the undulations of the hot mold surface and always keep in close contact with the hot mold, thereby maintaining a good contact state between the scraper 62 and the hot mold and ensuring the cleaning effect of the hot mold.

[0054] As Figure 10 shown, the adjusting unit 67 includes a slider 671, an adjusting plate 672, and a rotating rod 673. The scraper 62 is provided with a second sliding groove 621. The slider 671 is slidably connected to the second sliding groove 621. The slider 671 abuts against the adjusting plate 672. The adjusting plate 672 is fixedly connected to the rotating rod 673. The rotating rod 673 is rotatably connected to the scraper 62.

[0055] Through the slider 671, when the scraper 62 moves with the bracket 61 and the slider 671 encounters an obstacle and moves in the opposite direction, due to the slider 671 abutting against the adjusting plate 672, the adjusting plate 672 is fixed to the rotating rod 673, and the rotating rod 673 is rotatably connected to the scraper 62, the adjusting plate 672 rotates along the rotating rod 673, thereby pushing the scraper 62 to rotate, so as to adjust the angle of the scraper 62.

[0056] As Figure 7 shown, the lifting mechanism 4 includes a cylinder 41, a second sliding rod 42, and a slide rail 43. The cylinder 41 is fixedly connected to the frame 1. The slide rail 43 is fixedly connected to the frame 1. The second sliding rod 42 is slidably connected to the slide rail 43. The output end of the cylinder 41 is fixedly connected to the first template 31. The second sliding rod 42 is fixedly connected to the first template 31.

[0057] By the driving force of the linear motion generated by the output end of the cylinder 41, and the second sliding rod 42 is slidably connected to the slide rail 43 to provide a guiding effect for the first template 31, enabling it to smoothly perform linear sliding, and then the first template 31 can move up or down along a predetermined linear trajectory to meet the requirements of the welding device for adjusting the position of the first template 31 at different working stages.

[0058] Working principle: The cylinder 41 drives the two template mechanisms 3 to move towards the hot die mechanism 2, so that the bearing 35 enters the third sliding groove 241. The bearing 35 on the lower side rises linearly along the third sliding groove 241. When the bearing 35 enters the first inclined surface 2411, the bearing 35 changes from rising linearly to rising obliquely to the left, causing the second template 33 to move to the left accordingly, avoiding the interference area of the hot die. The first template 31 continues to rise. When the bearing 35 enters the second inclined surface 2412, the bearing 35 changes from rising linearly to rising obliquely to the right, and the second template 33 moves to the right accordingly. The upper first template 31 and the lower first template 31 move in opposite directions, aligning the workpiece and the hot die. By continuously applying pressure through the cylinder 41, the workpiece to be welded is melted. By retracting the cylinder 41, the workpiece to be welded is withdrawn from the hot die mechanism 2. Through the cooperation of the first linear module 25 and the first linear guide 26, the first linear module 25 drives the hot template 21 to move, causing the hot template 21 to drive the lower hot die 22 and the upper hot die 23 to move backward. By driving the two template mechanisms 3 to move relative to each other through the cylinder 41, the workpiece is welded. The airflow generated by the cooling fan 51 is introduced into the cooling channel 211 through pipeline connection. By bringing the bimetallic strip 55 close to the welded workpiece, the bimetallic strip 55 will bend and deform when heated, pushing the connecting plate 53 to move in the installation groove 213, causing the baffle 52 fixedly connected thereto to move synchronously in the first sliding groove 212, thereby changing the ventilation cross-sectional area of the cooling channel 211, controlling the wind speed, and enabling the workpiece to be cooled quickly and evenly. By driving the bracket 61 fixed to its sliding end through the second linear module 63, the scraper 62 is driven to move towards the hot die. The elastic unit 66 abuts against the scraper 62, enabling the scraper 62 to slide into the bracket 61 adaptively according to the contact position with the hot die during the movement and always maintaining good contact with the hot die, thereby removing impurities such as molten materials adhering to the hot die.
