Description

Technical Field

[0001] This application relates to the field of pulp molding technology, and in particular to a molding equipment and a pulp molding product production line. Background Technology

[0002] In the molding process of pulp molding products, a wet preform needs to be placed between an upper mold and a lower mold for hot pressing to form a dry preform. In related technologies, to ensure the closing accuracy of the upper and lower molds, guide pillars are inserted through at least one of the molds. The upper and lower ends of the guide pillars are fixedly connected to the upper and lower supports of the machine frame, respectively. When the upper and lower molds close, the guide pillars bear force and transmit the force to the upper and lower supports. Therefore, both the upper and lower supports need to be reinforced to improve their structural strength, resulting in higher production costs. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a molding device that can transfer most of the force on the guide post to the upper support, thereby reducing the force on the lower support, eliminating the need for additional reinforcing structures on the lower support, and reducing production costs.

[0004] This application also proposes a pulp molding product production line with the above-mentioned molding equipment.

[0005] A molding apparatus according to a first aspect of this application includes a frame and a hot pressing mechanism.

[0006] The frame includes an upper support and a lower support connected to each other, the upper support being located above the lower support, and the upper support being provided with a reinforcing structure; The hot pressing mechanism includes a hot pressing upper mold, a hot pressing lower mold, a second mold closing driver, and a guide post. The upper end of the guide post is fixedly connected to the upper support. The hot pressing upper mold is connected to the upper support. The lower support has a limiting hole. The lower end of the guide post passes through the limiting hole. The guide post passes through the hot pressing lower mold along the height direction. The hot pressing lower mold is slidably engaged with the guide post. The second mold closing driver is connected to the hot pressing lower mold and is used to drive the hot pressing lower mold to rise and fall to close with the hot pressing upper mold.

[0007] The molding apparatus according to the first aspect of this application has at least the following beneficial effects: the wet blank is transferred between the hot pressing upper mold and the hot pressing lower mold, and then the second mold closing driver drives the hot pressing lower mold to rise. The hot pressing lower mold slides relative to the guide post, and the hot pressing lower mold closes with the hot pressing upper mold. At least one of the hot pressing upper mold and the hot pressing lower mold has a heating structure, so that the wet blank is hot-pressed when the hot pressing upper mold and the hot pressing lower mold are closed, and the wet blank forms a dry blank. The guide post plays a guiding role in the rising process of the hot pressing lower mold, thereby improving the mold closing accuracy of the hot pressing lower mold and the hot pressing upper mold. It should be understood that the upper end of the guide post is fixedly connected to the upper support, and the lower end of the guide post passes through the limiting hole of the lower support. That is, the guide post is suspended on the upper support, and most of the force on the guide post is transferred to the upper support. The hot-pressing lower mold is installed on the guide post. Most of the force generated during the mold closing process of the hot-pressing lower mold and the hot-pressing upper mold will be transferred to the upper support through the guide post. That is, the upper support is the main load-bearing structure. Furthermore, the hot-pressing upper mold is installed on the upper support. Thus, the load required during the installation process of the hot-pressing upper mold and the hot-pressing lower mold and the force during the movement process are concentrated on the upper support. Therefore, it is only necessary to set a reinforcing structure on the upper support to strengthen and ensure the structural strength of the upper support. There is no need to add a reinforcing structure to the lower support, thereby reducing the production cost of the molding equipment of this application.

[0008] According to some embodiments of this application, the second mold clamping driver includes a second motor and a linkage structure, wherein the second motor is connected to the hot-pressing lower mold through the linkage structure.

[0009] According to some embodiments of this application, the hot pressing mechanism further includes a mounting base and an adjustment driver. The mounting base is located below the lower hot pressing mold. The connecting rod structure is disposed between the mounting base and the lower hot pressing mold. The connecting rod structure is connected to the mounting base and the lower hot pressing mold respectively. The second motor is mounted on the mounting base. The adjustment driver is connected to the mounting base to drive the mounting base to rise and fall. The second motor is mounted on the mounting base.

[0010] According to some embodiments of this application, the linkage structure includes a first linkage, a second linkage, and a third linkage. One end of the first linkage is rotatably connected to the hot-pressing lower mold, one end of the second linkage is rotatably connected to the mounting base, one end of the third linkage is connected to the drive end of the second motor, and the other ends of the first linkage, the second linkage, and the third linkage are rotatably connected.

[0011] According to some embodiments of this application, the guide post passes through the mounting base, and the mounting base and the guide post are slidably engaged.

[0012] According to some embodiments of this application, the linkage structure is provided in multiple sets.

[0013] According to some embodiments of this application, the adjustment driver includes a third motor, a transmission chain, transmission teeth, and a transmission sleeve. The third motor is mounted on the mounting base and drives the transmission chain. The transmission chain winds around and meshes with the transmission teeth. The transmission teeth are sleeved on the outside of the transmission sleeve and are fixedly connected to the transmission sleeve. The transmission sleeve is sleeved on the outside of the guide post. The inner side of the transmission sleeve is threadedly engaged with the outer side of the guide post. The mounting base is connected to the transmission sleeve.

[0014] According to some embodiments of this application, the second mold clamping driver further includes a plurality of cylinders, the cylinders being mounted on the mounting base, and the driving end of the cylinders being connected to the hot-pressing lower mold.

[0015] According to some embodiments of this application, the reinforcing structure includes multiple reinforcing ribs, which are staggered at the upper end of the upper support.

[0016] A pulp molding production line according to a second aspect of this application includes the molding equipment of the first aspect embodiment.

[0017] The pulp molding production line according to the second aspect embodiment of this application has at least the following beneficial effects: including all the beneficial effects of the molding equipment of the first aspect embodiment, which will not be repeated here.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0026] Reference Figures 1 to 4 The molding apparatus according to the first aspect of this application includes: a frame 100 and a hot pressing mechanism 200.

[0027] The frame 100 includes an upper support 110 and a lower support 120 connected to each other. The upper support 110 is located above the lower support 120 and is provided with a reinforcing structure 111. The hot pressing mechanism 200 includes a hot pressing upper mold 210, a hot pressing lower mold 220, a second mold closing driver 230, and a guide post 240. The upper end of the guide post 240 is fixedly connected to the upper support 110. The hot pressing upper mold 210 is connected to the upper support 110. The lower support 120 has a limiting hole 121. The lower end of the guide post 240 passes through the limiting hole 121. The guide post 240 passes through the hot pressing lower mold 220 along the height direction. The hot pressing lower mold 220 and the guide post 240 are slidably engaged. The second mold closing driver 230 drives the hot pressing lower mold 220 to rise and fall to close with the hot pressing upper mold 210.

[0028] Understandably, the wet blank is transferred between the hot pressing upper mold 210 and the hot pressing lower mold 220. Subsequently, the second mold closing driver 230 drives the hot pressing lower mold 220 to rise. The hot pressing lower mold 220 slides relative to the guide post 240, and the hot pressing lower mold 220 closes with the hot pressing upper mold 210. At least one of the hot pressing upper mold 210 and the hot pressing lower mold 220 has a heating structure. Thus, when the hot pressing upper mold 210 and the hot pressing lower mold 220 close, the wet blank is hot-pressed, and the wet blank forms a dry blank. The guide post 240 guides the rising process of the hot pressing lower mold 220, improving the mold closing accuracy of the hot pressing lower mold 220 and the hot pressing upper mold 210. It should be understood that the upper end of the guide post 240 is fixedly connected to the upper bracket 110, and the lower end of the guide post 240 passes through the limiting hole 121 of the lower bracket 120. That is, the guide post 240 is suspended on the upper bracket 110, and most of the force on the guide post 240 is transmitted to the upper bracket 110. The hot pressing lower mold 220 is installed on the guide post 240, and most of the force generated during the mold closing process of the hot pressing lower mold 220 and the hot pressing upper mold 210 will be transmitted to the upper bracket 110 through the guide post 240. That is, the upper bracket 110 acts as... The upper hot-pressing mold 210 is the main load-bearing structure, and the upper hot-pressing mold 210 is installed on the upper support 110. Thus, the load required during the installation process of the upper hot-pressing mold 210 and the interaction force during the movement process of the lower hot-pressing mold 220 are concentrated on the upper support 110. Therefore, it is only necessary to provide a reinforcing structure 111 on the upper support 110 to strengthen and ensure the structural strength of the upper support 110. There is no need to add a reinforcing structure 111 to the lower support 120, thereby reducing the production cost of the molding equipment of this application.

[0029] Specifically, a coupling 122 is provided in the limiting hole 121 of the lower bracket 120. The coupling 122 is, for example, a bushing or a shrink sleeve. The lower end of the guide post 240 passes through the inner ring of the coupling 122, so that the lower end of the guide post 240 is tightly connected to the lower bracket 120, avoiding the guide post 240 being too long and causing the lower end of the guide post 240 to swing during the movement of the hot pressing mold 220, thereby improving the installation stability of the guide post 240.

[0030] Specifically, there are four guide pillars 240, which pass through the four corners of the hot pressing mold 220.

[0031] Reference Figure 2 and Figure 3 According to some embodiments of this application, the second mold clamping driver 230 includes a second motor 231 and a connecting rod structure 232, wherein the second motor 231 is connected to the hot-pressing lower mold 220 through the connecting rod structure 232.

[0032] It is understandable that the second motor 231 drives the hot pressing lower mold 220 to rise and fall through the connecting rod structure 232. It should be understood that by replacing the hydraulic press commonly used in the prior art with the second motor 231 to drive the hot pressing lower mold 220, the risk of oil leakage from the hydraulic press leading to product contamination can be avoided. Furthermore, the connecting rod structure 232 can increase the driving force of the second motor 231, ensuring the mold closing pressure of the hot pressing upper mold 210 and the hot pressing lower mold 220.

[0033] Reference Figure 2 and Figure 3 According to some embodiments of this application, the hot pressing mechanism 200 further includes a mounting base 250 and an adjustment driver 260. The mounting base 250 is located below the hot pressing lower mold 220. A connecting rod structure 232 is disposed between the mounting base 250 and the hot pressing lower mold 220. The connecting rod structure 232 is connected to the mounting base 250 and the hot pressing lower mold 220 respectively. A second motor 231 is mounted on the mounting base 250. The adjustment driver 260 drives the mounting base 250 to drive the mounting base 250 to rise and fall. The second motor 231 is mounted on the mounting base 250.

[0034] Understandably, during the process of the second motor 231 driving the hot-pressing lower mold 220 to rise and close the mold via the connecting rod structure 232, in order to ensure the pressurization effect of the connecting rod structure 232, the connecting rod structure 232 needs to swing to the optimal position when the hot-pressing lower mold 220 and the hot-pressing upper mold 210 are closed. However, when producing different products, the thickness of the hot-pressing lower mold 220 will change, which will cause the mold closing distance of the hot-pressing lower mold 220 to change. When the second motor 231 drives the hot-pressing lower mold 220 to close the mold via the connecting rod structure 232, the connecting rod structure 232 may not be able to swing to the optimal position. For example, if the hot-pressing lower mold 220 becomes thicker, the distance between the hot-pressing lower mold 220 and the hot-pressing upper mold 210 becomes smaller, and the driving stroke of the second motor 231 becomes shorter. When the hot-pressing lower mold 220 and the hot-pressing upper mold 210 are closed, the connecting rod structure 232 does not swing to the optimal position.

[0035] Therefore, a mounting base 250 is added, and a connecting rod structure 232 is set between the mounting base 250 and the hot pressing lower mold 220. The second motor 231 is also mounted on the mounting base 250. By adjusting the driver 260, the mounting base 250 is driven to rise and fall, thereby changing the distance between the hot pressing lower mold 220 and the hot pressing upper mold 210. Thus, when the hot pressing lower mold 220 is replaced, the distance between the hot pressing upper mold 210 and the hot pressing lower mold 220 can be kept constant. That is, when the second motor 231 drives the hot pressing lower mold 220 to close the mold through the connecting rod structure 232, the connecting rod structure 232 can swing to the optimal position.

[0036] Reference Figure 5According to some embodiments of this application, the linkage structure 232 includes a first linkage 232a, a second linkage 232b, and a third linkage 232c. One end of the first linkage 232a is rotatably connected to the hot press mold 220, one end of the second linkage 232b is rotatably connected to the mounting base 250, one end of the third linkage 232c is connected to the drive end of the second motor 231, and the other ends of the first linkage 232a, the second linkage 232b, and the third linkage 232c are rotatably connected.

[0037] Understandably, in the initial state, the lower hot press mold 220 and the upper hot press mold 210 are far apart, and the first connecting rod 232a and the second connecting rod 232b are in a folded state, that is, the included angle between the first connecting rod 232a and the second connecting rod 232b is an acute angle. When the lower hot-pressing mold 220 and the upper hot-pressing mold 210 need to be closed, the second motor 231 drives the third connecting rod 232c to push the first connecting rod 232a and the second connecting rod 232b to swing. One end of the first connecting rod 232a rotates relative to the lower hot-pressing mold 220, and one end of the second connecting rod 232b rotates relative to the mounting base 250. The included angle between the first connecting rod 232a and the second connecting rod 232b increases, so that the lower hot-pressing mold 220 moves away from the mounting base 250, that is, the lower hot-pressing mold 220 rises and approaches the upper hot-pressing mold 210. When the lower hot-pressing mold 220 and the upper hot-pressing mold 210 are closed, the first connecting rod 232a and the second connecting rod 232b are on the same straight line, that is, the included angle between the first connecting rod 232a and the second connecting rod 232b is 180°. At this time, the connecting rod structure 232 reaches the optimal position, and the pressure boosting effect of the connecting rod structure 232 is maximized.

[0038] It is also understandable that when the thickness of the lower hot-pressing mold 220 increases, the closing distance between the lower hot-pressing mold 220 and the upper hot-pressing mold 210 becomes shorter. The first connecting rod 232a and the second connecting rod 232b cannot swing to an angle of 180°. Therefore, the adjusting driver 260 can drive the mounting base 250 to move down, thereby moving the connecting rod structure 232 and the lower hot-pressing mold 220 down, so that the closing distance between the lower hot-pressing mold 220 and the upper hot-pressing mold 210 remains unchanged. This ensures that when the lower hot-pressing mold 220 and the upper hot-pressing mold 210 are closed, the first connecting rod 232a and the second connecting rod 232b can swing to an angle of 180°.

[0039] Specifically, the connection between the first connecting rod 232a and the hot-pressing lower mold 220 and the connection between the second connecting rod 232b and the mounting base 250 are on the same vertical line. That is, the line connecting the first connecting rod 232a and the hot-pressing lower mold 220 and the second connecting rod 232b and the mounting base 250 is perpendicular to the horizontal plane, which further improves the pressurization effect of the connecting rod structure 232.

[0040] Reference Figure 4According to some embodiments of this application, the guide post 240 passes through the mounting base 250, and the mounting base 250 and the guide post 240 are in sliding engagement.

[0041] It is understandable that the guide post 240 passes through the mounting base 250. When the adjustment driver 260 drives the mounting base 250 to rise and fall, the mounting base 250 can slide along the guide post 240, thereby ensuring the positional accuracy of the mounting base 250.

[0042] Specifically, there are four guide posts 240, which pass through the four corner ends of the mounting base 250.

[0043] Reference Figure 5 According to some embodiments of this application, the linkage structure 232 is provided with multiple sets.

[0044] Understandably, by setting multiple sets of connecting rod structures 232, the upward driving force on the lower hot press mold 220 can be made uniform. When the lower hot press mold 220 and the upper hot press mold 210 are closed, the pressure on the wet blank is uniform, ensuring that the wet blank is subjected to uniform force and that the thickness variation of the wet blank is uniform. For example, if the product is a cup lid, and the cup lid needs to fit the cup, when the second motor 231 is only connected to the middle position of the lower hot press mold 220, the force on the cup lid is concentrated in the middle position, resulting in less force on the edge of the cup lid and less edge variation, causing the outer diameter of the cup lid to fail to reach the corresponding size. Therefore, by setting multiple sets of connecting rod structures 232, the driving force of the second motor 231 can be transmitted to the middle and edges of the lower hot press mold 220, so that the pressure on the wet blank is as uniform as possible, improving the dimensional accuracy of the product.

[0045] Specifically, at least two sets of linkage structures 232 are provided. It should be understood that each set of linkage structures 232 includes two linkage structures 232, wherein the included angle between the first link 232a and the second link 232b of the two linkage structures 232 in one set of linkage structures 232 faces each other, that is, the first link 232a and the second link 232b of the two linkage structures 232 are mirror images of each other. Furthermore, the connection positions of the multiple sets of linkage structures 232 with the hot-pressing mold 220 are distributed along the contour shape of the product. For example, if the product is a cup lid, the connection positions of the multiple sets of linkage structures 232 with the hot-pressing mold 220 are distributed circumferentially. Of course, the product can also be other types of products, and this is not limited here.

[0046] Reference Figure 4According to some embodiments of this application, the adjustment driver 260 includes a third motor 261, a transmission chain (not shown in the figure), a transmission tooth 262, and a transmission sleeve 263. The third motor 261 is mounted on the mounting base 250 and drives the transmission chain. The transmission chain is wound around the transmission tooth 262 and meshes with the transmission tooth 262. The transmission tooth 262 is sleeved on the outside of the transmission sleeve 263 and is fixedly connected to the transmission sleeve 263. The transmission sleeve 263 is sleeved on the outside of the guide post 240. The inner side of the transmission sleeve 263 is threadedly engaged with the outer side of the guide post 240. The mounting base 250 is connected to the transmission sleeve 263.

[0047] Understandably, the third motor 261 drives the transmission chain to rotate, and the transmission chain meshes with the transmission gear 262, thereby driving the transmission gear 262 to rotate. The transmission gear 262 drives the transmission sleeve 263 to rotate. Since the inner side of the transmission sleeve 263 is threadedly engaged with the outer side of the guide post 240, the transmission sleeve 263 can move up and down along the axial direction of the guide post 240 during the rotation of the transmission sleeve 263. The transmission sleeve 263 drives the mounting base 250 to move up and down.

[0048] Specifically, there are four guide posts 240, and the number of transmission teeth 262 and transmission sleeves 263 corresponds one-to-one with the number of guide posts 240. The transmission chain meshes with the four transmission teeth 262, so that a third motor 261 simultaneously drives the four transmission sleeves 263 to rise and fall relative to the guide posts 240.

[0049] Reference Figure 2 and Figure 3 According to some embodiments of this application, the second mold clamping driver 230 further includes a plurality of cylinders 233, which are mounted on the mounting base 250 and the driving end of the cylinders 233 is connected to the hot press mold 220.

[0050] It is understandable that the cylinder 233 assists the second motor 231 in driving the lower hot-pressing mold 220, thereby increasing the mold-closing pressure between the lower hot-pressing mold 220 and the upper hot-pressing mold 210. Furthermore, when the lower hot-pressing mold 220 and the upper hot-pressing mold 210 open, the cylinder 233 can release pressure to buffer the mold-opening process of the lower hot-pressing mold 220.

[0051] Reference Figure 1 According to some embodiments of this application, the reinforcing structure 111 includes multiple reinforcing ribs 111a, which are staggered at the upper end of the upper support 110.

[0052] Understandably, the multiple reinforcing ribs 111a are arranged in an alternating pattern to improve the structural strength of the upper support 110.

[0053] Specifically, the reinforcing rib 111a includes a first rib and a second rib. Multiple first ribs and multiple second ribs are provided. Multiple first ribs are arranged in parallel, multiple second ribs are arranged in parallel, and the first ribs and the second ribs are arranged perpendicular to each other.

[0054] Reference Figures 1 to 4 The pulp molding production line according to the second aspect of this application includes the molding equipment of the first aspect embodiment.

[0055] The pulp molding production line according to the second aspect embodiment of this application has at least the following beneficial effects: including all the beneficial effects of the molding equipment of the first aspect embodiment, which will not be repeated here.

[0056] Reference Figure 1 According to some embodiments of this application, the pulp molding product production line also includes a molding mechanism 300 and a feeding mechanism 400.

[0057] The molding mechanism 300 includes a slurry pool 310, an upper molding die 320, a lower molding die 330, a first mold closing driver 340, and a translation driver 350. The lower molding die 330 is disposed in the slurry pool 310. The translation driver 350 drives and connects to the upper molding die 320, and is used to drive the upper molding die 320 to move above the lower molding die 330 or above the hot pressing lower die 220. The first mold closing driver 340 drives and connects to the lower molding die 330, and is used to drive the lower molding die 330 to rise and fall. The unloading mechanism 400 includes an unloading platform 410 and a lifting driver 420, wherein the lifting driver 420 drives and connects to the unloading platform 410. The hot pressing upper mold 210 is fixedly connected to the forming upper mold 320 and moves synchronously. When the forming upper mold 320 moves above the forming lower mold 330, the hot pressing upper mold 210 moves above the hot pressing lower mold 220. When the forming upper mold 320 moves above the hot pressing lower mold 220, the hot pressing upper mold 210 moves above the unloading platform 410.

[0058] Understandably, firstly, the upper forming die 320 is located above the lower forming die 330, and the upper hot pressing die 210 is located above the lower hot pressing die 220. The pulp tank 310 contains pulp, and the lower forming die 330 can absorb the pulp in the pulp tank 310, causing paper scraps in the pulp to adhere to the cavity of the lower forming die 330. The first die-closing driver 340 drives the lower forming die 330 to rise, and the lower forming die 330 closes with the upper forming die 320 located above the lower forming die 330, shaping the paper scraps to form the second wet blank. At the same time, the first wet blank is placed at the lower hot pressing die 220, and the second die-closing driver 230 drives the lower hot pressing die 220 to rise and close with the upper hot pressing die 210 to hot press the first wet blank, forming the first dry blank.

[0059] Subsequently, the upper forming mold 320 and the lower forming mold 330 open, with the upper forming mold 320 having a first suction hole that can communicate with a vacuum device, and the upper forming mold 320 holding the second wet blank. The upper hot pressing mold 210 and the lower hot pressing mold 220 open, with the upper hot pressing mold 210 having a second suction hole that can communicate with a vacuum device, and the upper hot pressing mold 210 holding the first dry blank.

[0060] Next, the translation driver 350 drives the forming upper mold 320 and the hot pressing lower mold 220 to move forward simultaneously. The forming upper mold 320 moves above the hot pressing lower mold 220, and the hot pressing upper mold 210 moves above the unloading platform 410. The second mold closing driver 230 drives the hot pressing lower mold 220 to rise, and the hot pressing lower mold 220 closes with the forming upper mold 320. The forming upper mold 320 releases its grip on the second wet blank, allowing the second wet blank to transfer to the hot pressing lower mold 220. The lifting driver 420 drives the unloading platform 410 to rise and approach the hot pressing upper mold 210. The hot pressing upper mold 210 releases its grip on the first dry blank, allowing the first dry blank to fall onto the unloading platform 410.

[0061] Then, the translational actuator 350 drives the upper forming mold 320 and the lower hot pressing mold 220 to move backward simultaneously. The upper forming mold 320 is positioned above the lower forming mold 330, and the upper hot pressing mold 210 is positioned above the lower hot pressing mold 220. The lower forming mold 330 then works with the upper forming mold 320 to form the third wet blank, and the lower hot pressing mold 220 works with the upper hot pressing mold 210 to hot press the second wet blank into a second dry blank. This process is repeated, causing the upper forming mold 320 to continuously transfer the wet blank to the lower hot pressing mold 220, and the upper hot pressing mold 210 to continuously transfer the dry blank to the unloading platform 410, stacking the dry blanks on the unloading platform 410. Under the action of the lifting actuator 420, the unloading platform 410 can continuously descend as the dry blanks are stacked to ensure a certain space between the upper hot pressing mold 210 and the stacked dry blanks. After a certain number of dry blanks are stacked on the unloading platform 410, they can be transferred to the next process by a robot or manually.

[0062] It should be understood that the driving direction of the translation driver 350 is consistent with the distribution direction of the lower forming die 330, the lower hot pressing die 220 and the unloading platform 410, while the distance between the upper forming die 320 and the upper hot pressing die 210 is the same as the distance between the lower forming die 330 and the lower hot pressing die 220 and the distance between the lower hot pressing die 220 and the unloading platform 410.

[0063] In summary, the lower forming mold 330 and the slurry pool 310 work together to form a wet blank, while the upper hot pressing mold 210 and the lower hot pressing mold 220 work together to form a dry blank. The translation driver 350 can drive the upper forming mold 320 and the lower hot pressing mold 220 to move simultaneously, so that the upper forming mold 320 moves above the lower hot pressing mold 220, and the lower hot pressing mold 220 moves above the unloading platform 410. Under the driving action of the second mold closing driver 230, the upper forming mold 320 can transfer the wet blank to the lower hot pressing mold 220, and under the driving action of the lifting driver 420, the upper hot pressing mold 210 can transfer the dry blank to the unloading platform 410. Thus, by transferring the wet and dry blanks through the upper forming mold 320 and the upper hot pressing mold 210, the use of robotic arms is reduced, and production costs are lowered.

[0064] Specifically, both the upper forming mold 320 and the upper hot pressing mold 210 can be slidably mounted on the upper support 110.

[0065] Specifically, the feeding mechanism 400 also includes a material picking component 430 and a conveyor belt 440. The material picking component 430 can adsorb or grab the dry blanks on the feeding platform 410 and transfer the dry blanks to the conveyor belt 440, which then transports the dry blanks to the next process.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
