Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, and in particular to a compression molding device. Background Technology

[0002] Existing compression molding equipment suffers from poor heat dissipation. Due to its structural design, the base has limited contact area with the external environment. During the compression molding process, the base generates a significant amount of heat due to continuous heating; however, due to poor heat dissipation, this heat is difficult to dissipate quickly. As heat accumulates, the base temperature continues to rise, eventually leading to heat deformation. Once the base deforms, it not only affects the overall structural stability of the compression molding equipment but also severely negatively impacts the quality of the compression molding process, resulting in increased product defect rates, higher production costs, and reduced production efficiency.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Figure 1 A schematic diagram of the structure of the medium-pressure synthesis device of this utility model is shown. Figure 2 A schematic diagram of the fixing plate in this utility model is shown. Figure 3 It shows Figure 2 Enlarged view of point A, Figure 4 The first front view of the linkage assembly of this utility model is shown. Figure 5The second front view of the linkage assembly of this utility model is shown. The pressing and forming device includes: a frame, a pressing seat 2 disposed in the middle of the frame, multiple driving cylinders, and a pressing assembly. The pressing seat 2 includes: a support plate 21, a support base 22, and multiple hollow support tubes 23. The support plate 21 is provided with multiple first heat dissipation holes 211, and the support base 22 is provided with multiple second heat dissipation holes 221. One end of any hollow support tube 23 is connected to the corresponding first heat dissipation hole 211, and the other end of the hollow support tube 23 is connected to the corresponding second heat dissipation hole 221, forming a hollow pressing seat 2. The pressing assembly 4 includes: a fixing plate 41, a pressing plate 42, a driving mechanism 43, and multiple driving cylinders. The pressing plate 42 is driven by the multiple driving cylinders and the driving mechanism 43 to move away from the pressing seat 2, and the pressing plate 42 is driven by the driving mechanism 43 and the weight of the pressing plate 42 to move closer to the pressing seat 2. In this embodiment, the support plate 21 is provided with a plurality of first heat dissipation holes 211, and the plurality of first heat dissipation holes 211 are arrayed on the support plate 21. The support base 22 is also provided with the same number of second heat dissipation holes 221 as the first heat dissipation holes 211, and the plurality of second heat dissipation holes 221 are distributed on the support base 22 in a position corresponding to the plurality of first heat dissipation holes 211. The number of hollow support tubes 23 is the same as the number of first heat dissipation holes 211 and second heat dissipation holes 221, and one end of the hollow support tube 23 is connected to its corresponding first heat dissipation hole 211, and the other end of the hollow support tube 23 is connected to its corresponding second heat dissipation hole 221, so that the pressing base 2 forms a hollow pressing base, increasing the contact area between the pressing base 2 and the external environment, avoiding the heat of the heating mold from being transferred to the base, which would cause the hollow support tube 23 to deform due to heat, and facilitating the rapid heat dissipation of the base 2, reducing the risk of the base 2 deforming due to heat. Furthermore, the base 2 has a hollow design, which can disperse the stress on the base 2. When pressing, the base 2 is subjected to the pressure output by the pressing plate 42, which avoids the pressure output by the pressing plate 42 from being concentrated and causing the base 2 to deform under force. This helps to disperse the stress on the base 2 and reduce the risk of the base 2 being deformed under force.

[0033] The fixing plate 41 is disposed on the top of the frame 1, the pressing plate 42 is slidably mounted on the frame 1, and the driving mechanism 43 is located at the bottom of the fixing plate 41, and the driving mechanism 43 can drive the pressing plate 42 to move along the height direction of the frame 1. The pressing assembly has four driving cylinders 3, which are respectively located at the four apex corners of the driving mechanism 43, and the output end of each driving cylinder 3 is fixedly connected to the pressing plate 42.

[0034] Specifically, when the drive mechanism 43 and the four drive cylinders 3 simultaneously output power to move the pressing plate 42 upward, the four drive cylinders 3 simultaneously output lifting force from the four corners of the pressing plate 42, with each corner bearing a portion of the force. This reduces the lifting force output by the drive mechanism 43 at the center of the pressing plate 42, thereby reducing the electrical energy output by the drive mechanism 43. This prevents the drive mechanism 43 from repeatedly performing high-load work and causing damage, which helps to extend the service life of the drive mechanism 43 and reduce its workload, thus reducing the electrical energy consumed. When the drive mechanism 43 outputs power to move the pressing plate 42 downward, the pressing plate 42 moves downward under the influence of its own weight and the drive of the drive mechanism 43. That is, the drive mechanism first outputs power to the pressing plate, and then the drive mechanism stops outputting power, so that the pressing plate moves towards the pressing seat only under its own weight. This avoids the drive mechanism 43 needing to output power to counteract the weight of the pressing plate 42 in order to ensure that the drive mechanism can press downward at a uniform speed, which would require the drive mechanism 43 to output a large lifting force. This reduces the risk of damage to the drive mechanism 43 due to repeated high-load work, reduces the workload of the drive mechanism 43, and thus reduces the power consumption.

[0035] Furthermore, the drive mechanism 43 includes: a first drive motor 431, a crank 432, a rocker arm 433 connected to the crank 432, a connecting block 435, and a plurality of connecting rod groups 434; one end of the crank 432 is installed at the output end of the first drive motor 431, the other end of the crank 432 is connected to one end of the rocker arm 433, the other end of the rocker arm 433 is connected to the connecting block 435, the connecting block 435 is connected to the plurality of connecting rod groups 434, and the plurality of connecting rod groups 434 are symmetrically distributed in pairs based on the connecting blocks 435, and one end of any connecting rod group 434 is rotatably connected to the pressing plate 42. In this embodiment, the drive mechanism 43 includes four connecting rod groups 434, the four connecting rod groups 434 are respectively located at the four apex corners of the connecting block 435, and one end of any connecting rod group 434 is rotatably connected to the pressing plate 42. Driven by the first drive motor 431, the crank 432 can rotate, which in turn drives the rocker arm 433 to move up and down, so that the rocker arm 433 can drive the connecting block 435 to move up and down, thereby driving the four sets of connecting rods 434 to retract or expand, so as to drive the pressing plate 42 to move in the vertical direction.

[0036] It should be noted that the first drive motor 431 outputs power to drive the crank 432 to rotate forward, which in turn drives the rocker arm 433 to move downward. This causes the rocker arm 433 to drive the connecting block 435 to move downward, which in turn causes the multiple connecting rod assemblies 434 to unfold, moving the pressing plate 42 downward and applying pressure to the corresponding workpiece to achieve the pressing operation. Conversely, the first drive motor 431 outputs power to drive the crank 432 to rotate in the opposite direction, which in turn drives the rocker arm 433 to move upward. This causes the rocker arm 433 to drive the connecting block 435 to move upward, which in turn causes the connecting rod assemblies 434 to retract, moving the pressing plate 42 upward.

[0037] Further, any of the connecting rod assemblies 434 includes: a first connecting rod 4341, a second connecting rod 4342, and a third connecting rod 4343; one end of the first connecting rod 4341 is rotatably connected to the fixed plate 41, the other end of the first connecting rod 4341 is rotatably connected to one end of the second connecting rod 4342, the other end of the second connecting rod 4342 is rotatably connected to the pressing plate 42, one end of the third connecting rod 4343 is rotatably connected to the first connecting rod 4341, and the other end of the third connecting rod 4343 is rotatably connected to the connecting block 435. When the connecting block 435 moves, the third connecting rod 4343 is driven by the connecting block 435 to swing, thereby driving the first connecting rod 4341 to swing, so that the included angle between the second connecting rod 4342 and the third connecting rod 4343 changes periodically, thereby enabling the pressing plate 42 to move closer to the pressing seat 2 or the pressing plate 42 to move away from the pressing seat 2.

[0038] Specifically, taking one set of connecting rods 434 as an example, when the connecting block 435 moves downward, the third connecting rod 4343 is driven by the connecting block 435 to swing forward. In turn, the third connecting rod 4343 drives the first connecting rod 4341 to swing forward, so that the second connecting rod 4342 swings in the opposite direction. At the same time, the second connecting rod 4342 is affected by the gravity of the pressing plate 42, causing the included angle between the second connecting rod 4342 and the third connecting rod 4343 to become a flat angle, so that the pressing plate 42 moves downward, and thus the pressing plate 42 moves closer to the pressing seat 2. Conversely, when the connecting block 435 moves upward, the third link 4343 is driven by the connecting block 435 to swing in the opposite direction. In turn, the third link 4343 drives the first link 4341 to swing in the opposite direction, so that the second link 4342 swings in the forward direction, making the included angle between the second link 4342 and the third link 4343 become an acute angle, causing the pressing plate 42 to move upward, and thus moving the pressing plate 42 away from the pressing seat 2.

[0039] Furthermore, the frame 1 includes a base 11 and multiple guide rods 12; the pressing seat 2 is disposed on the base 11, and the multiple guide rods 12 are evenly distributed at the four apex corners of the pressing seat 2, and the pressing plate 42 is movably sleeved on the multiple guide rods 12. In this embodiment, the frame 1 includes four guide rods 12, which are respectively distributed at the four apex corners of the pressing seat 2, and the pressing plate 42 is provided with corresponding connecting holes at the four apex corners, so that the pressing plate 42 can be slidably sleeved on the four guide rods 12, and the pressing plate 42 can slide up and down in the vertical direction on the guide rods 12, thereby adjusting the horizontal height of the pressing plate 42 on the frame 1 to adapt to the pressing requirements of workpieces of different sizes.

[0040] Furthermore, the fixed plate 41 is provided with a plurality of threaded sleeves 5, and the moving rod is correspondingly disposed at the top corner of the fixed plate 41; any one of the threaded sleeves 5 is movably inserted into the guide rod 12. In this embodiment, the fixed plate 41 is provided with four threaded sleeves 5, which are correspondingly disposed at the four top corners of the fixed plate 41. The four threaded sleeves 5 are movably disposed within the guide rod 12, wherein the end of the guide rod 12 near the fixed plate is also provided with threads that match the threaded sleeves 5. Through the threaded engagement between the threaded sleeves 5 and the guide rod 12, precise control of the movement distance and speed of the component can be achieved, that is, the height difference between the fixed plate 41 and the frame 1 can be adjusted, thereby adjusting the horizontal height of the pressing plate 42 on the frame 1 to adapt to the pressing requirements of workpieces of different sizes.

[0041] Furthermore, each of the threaded sleeves 5 is provided with a first transmission wheel 51, and each first transmission wheel 51 is connected based on a transmission belt 414. The transmission belt 414 moves under force and drives the threaded sleeve 5 to rotate. The rotation of the threaded sleeve 5 causes the fixed plate 41 to move in the vertical direction. When the transmission belt 414 moves, it drives the first transmission wheel 51 to rotate. The rotation of the first transmission wheel 51 causes the threaded sleeve 5 to rotate relatively, that is, the first transmission wheel 51 rotates while maintaining the corresponding position, causing the threaded sleeve 5 to move in a relative spiral motion relative to the first transmission wheel 51, ultimately changing the depth to which the threaded sleeve 5 is screwed into the corresponding guide rod 12. Since the guide rod 12 is fixed, the rotation of the threaded sleeve 5 drives the fixed plate 41 to move in the vertical direction, thereby adjusting the height of the fixed plate 41. In this embodiment, the first transmission wheel 51 has a cylindrical structure and internal threads that match the threaded sleeve 5 are machined inside. The first transmission wheel 51 remains in contact with the transmission belt 414 to ensure that the friction between the first transmission wheel 51 and the transmission belt 414 can drive the first transmission wheel 51 to rotate. When the transmission belt 414 moves, it drives the first transmission wheel 51 to rotate on the threaded sleeve 5, thereby realizing the rotation of the threaded sleeve 5. When the transmission belt 414 is subjected to force and moves in one direction, it drives the first transmission wheel 51 to rotate in the forward direction, thereby causing the threaded sleeve 5 to rotate upward within the guide rod 12, and the fixed plate 41 rises accordingly. During the movement, since each of the first transmission wheels 51 is connected through the transmission belt 414, precise synchronous rotation is achieved, thereby ensuring the smooth rise of the fixed plate 41 and reducing tilting or swaying. Conversely, the principle is the same when the transmission belt 414 is subjected to force and moves in another direction, causing the fixed plate 41 to descend accordingly, which will not be elaborated here.

[0042] It should be noted that the first transmission wheel 51 can be a sprocket or a pulley, and the transmission belt can be a chain or a belt. When the first transmission wheel 51 is a sprocket, the transmission belt 414 is a chain; when the first transmission wheel 51 is a pulley, the transmission belt is a belt, ensuring that the first transmission wheel 51 and the transmission belt 414 remain in contact to achieve precise synchronous rotation.

[0043] Specifically, when the fixed plate 41 reaches the predetermined height, the external force driving the transmission belt 414 disappears, the transmission belt 414 stops moving, the first transmission wheel 51 also stops rotating, and the threaded sleeve 5 stops moving within the guide rod 12, thus achieving precise positioning of the fixed plate 41. At this time, due to the self-locking property of the thread, the threaded sleeve 5 will remain in its current position, preventing movement due to slight interference from external forces, which helps the fixed plate 41 to stay stably at the corresponding height.

[0044] Furthermore, the fixed plate 41 is provided with a second drive motor 411 and a transmission mechanism 412. The output end of the second drive motor 411 meshes with the transmission mechanism 412, and the output end of the transmission mechanism 412 abuts against the transmission belt 414. The transmission mechanism 412 is driven by the second drive motor 411 to rotate, thereby driving the transmission belt 414 to move. In this embodiment, the output end of the transmission mechanism 412 is provided with a drive gear. The drive gear abuts against the transmission belt 414, and when the drive gear rotates, it can drive the transmission belt 414 to move, thereby realizing the adjustment of the height of the entire fixed plate 41 by one motor. When the second drive motor 411 outputs power, it drives the transmission mechanism 412 to start rotating. The output gear of the transmission mechanism 412 starts rotating, which in turn drives the transmission belt 414 to move. The transmission belt 414 moves and drives the four first transmission wheels 51 to start rotating, which in turn causes the threaded sleeve 5 to rotate within the guide rod 12, changing the depth of the threaded sleeve 5 in the guide rod 12. Finally, it changes the height of the fixed plate 41, achieving precise synchronous rotation and ensuring that the fixed plate 41 rises or falls smoothly.

[0045] Furthermore, the fixing plate 41 is provided with a plurality of second transmission wheels 413, which are evenly distributed on the fixing plate 41, and any one of the second transmission wheels 413 abuts against the transmission belt 414. In this embodiment, eight second transmission wheels 413 are provided on the fixed plate 41. The eight second transmission wheels 413 are evenly distributed on the fixed plate 41, that is, two second transmission wheels 413 are provided near each of the four sides of the fixed plate 41. The eight second transmission wheels 413 simultaneously abut against the transmission belt 414, keeping the transmission belt 414 taut during use. When the transmission belt 414 is taut, the contact between the transmission belt 414 and the second transmission wheels 413 is tighter, and the friction increases. According to the principle of friction transmission, the greater the friction, the more effective the power transmission and the less energy loss. The taut transmission belt 414 can ensure that there is no relative slippage between the pulley and the transmission belt 414, so that the driven wheel can rotate accurately according to the speed and direction of the driving wheel. This ensures that the transmission belt 414 can simultaneously drive multiple first transmission wheels 51 to rotate, so as to simultaneously adjust the depth of the threaded sleeve 5 screwed into the corresponding guide rod 12, avoiding the inability to move simultaneously, which would cause one side to be higher than the other, increasing additional resistance or generating unnecessary friction. Simultaneous movement ensures coordinated operation of all components and reduces energy loss.

[0046] It should be noted that the second transmission wheel 413 can be a sprocket or a pulley. When the first transmission wheel is a sprocket and the transmission belt 414 is a chain, the second transmission wheel 413 is a sprocket, and the three cooperate to ensure synchronous rotation. When the first transmission wheel is a pulley and the transmission belt 414 is a belt, the second transmission wheel 413 is a pulley, and the three cooperate to ensure synchronous rotation.

[0047] Furthermore, the fixing plate 41 is also provided with a plurality of pressing cylinders 415, which are distributed above the guide rod 12, and the output end of any pressing cylinder 415 is adapted to abut against the corresponding guide rod 12. In this embodiment, four pressing cylinders 415 are provided on the fixing plate 41. One of the four pressing cylinders 415 is distributed above one of the four guide rods 12. When the pressing cylinder 415 outputs pressure to the corresponding guide rod 12, that is, the output end of the pressing cylinder 415 abuts against the top of the corresponding guide rod 12, the output end of the pressing cylinder 415 exerts a force on the threaded sleeve, causing the inner thread of the threaded sleeve to compress the outer thread of the guide rod 12, eliminating the gap between them, increasing the contact area between them, and thus increasing the friction between the threaded sleeve and the corresponding guide rod 12. This avoids relative movement between the threaded sleeve 5 and the guide rod 12 during use, which would cause uneven pressure and affect the pressing effect. It is beneficial to transmit the pressure evenly to the pressing component according to the preset path and force, ensuring the pressing accuracy. When the pressing cylinder 415 is unloaded, it exerts no force on the threaded sleeve 5. At this time, the second drive motor 411 outputs power to make the threaded sleeve 5 rotate, thereby adjusting the height of the fixing plate 41 to adapt to the processing requirements of different workpieces.

[0048] Furthermore, any one of the aforementioned drive cylinders 3 is a single-sided venting cylinder. When the pressing plate 42 needs to be lifted upwards, the drive cylinder 3 vents air to provide lifting force to help the pressing plate 42 move upwards. When the pressing plate 42 descends, the drive cylinder 3 exhausts air to discharge the gas inside the drive cylinder 3, making it convenient to directly vent air to provide lifting force for the next lifting of the pressing plate 42. Moreover, the single-sided venting cylinder only has one chamber vented, avoiding the pressure fluctuation problem that may occur when switching venting chambers in a double-sided venting cylinder, making the cylinder movement smoother and the positioning accuracy higher.

[0049] In summary, this invention utilizes multiple hollow support tubes in the pressing and molding device, positioned between the support plate and the support base, to create a hollow pressing base. This increases the contact area between the pressing base and the external environment, preventing heat from the heating mold from being transferred to the support frame and fixing part of the base, thus avoiding heat deformation of the support frame and fixing part. This also facilitates rapid heat dissipation from the base, reducing the risk of heat deformation. Furthermore, this invention includes a driving mechanism and multiple driving cylinders. The multiple driving cylinders and the driving mechanism simultaneously output power to lift the pressing plate, and the driving cylinders... Multiple lifting force outputs reduce the lifting force required by the drive mechanism, thereby reducing the electrical energy output of the drive mechanism, alleviating the workload of the drive mechanism, and further reducing energy consumption. When the drive mechanism outputs power to move the pressing plate downwards, the pressing plate moves downwards due to its own gravity and the drive mechanism's downward drive, avoiding the need for the drive mechanism to output power to counteract the gravity of the pressing plate, which would otherwise require a large lifting force. This reduces the risk of damage to the drive mechanism due to repeated high-load operation, further reducing the workload of the drive mechanism and thus reducing energy consumption.

[0050] Furthermore, the above description provides a detailed description of the compression molding device provided in the embodiments of this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
