Description

Technical Field

[0001] This application relates to the field of mold manufacturing, and in particular to a mold grinding device with a reversing function. Background Technology

[0002] In the process of mass production of molds, grinding and finishing are key steps to ensure the precision, surface finish and functionality of the molds. By removing burrs, adjusting dimensional deviations and repairing minor defects, we can improve the molding quality and service life of the molds, ensure the dimensional consistency and surface finish of the products produced in batches, reduce demolding resistance, optimize product appearance, and ultimately improve production efficiency and finished product qualification rate.

[0003] After mold production is completed (e.g., by machine tool processing), burrs or rough edges may remain on the surface. To improve finishing efficiency, automated grinding equipment is typically used to process them. One type of mold grinding equipment includes a six-axis robotic arm and a conveying mechanism. The conveying mechanism intermittently transports the mold to be processed to the grinding station below the six-axis robotic arm. The tool end of the six-axis robotic arm is equipped with a grinding component. The controller of the grinding equipment coordinates the control of the six-axis robotic arm and the conveying mechanism to achieve the grinding process of the mold. After the current mold is processed, the controller controls the conveying mechanism to start working, thereby sending the next mold to be processed to the grinding station, resulting in high grinding efficiency.

[0004] After the mold is polished by the polishing equipment, it needs to be sent to the next processing equipment (such as painting, cleaning, heat treatment, or spraying an anti-oxidation coating). However, the space in the production workshop is limited, and operators or special handling equipment are needed to move the polished mold to the next processing equipment. The operation is complicated, and there is a risk of scratching or bumping the mold during the handling process. There is room for improvement. Utility Model Content

[0005] To facilitate the transportation of the polished mold, this application provides a mold polishing device with a reversing function.

[0006] The mold grinding device with reversing function provided in this application adopts the following technical solution:

[0007] A mold grinding device with a reversing function includes a frame and a grinding mechanism and a conveying mechanism mounted on the frame. One end of the frame is a loading end and the other end is a unloading end. The grinding mechanism is located between the loading end and the unloading end of the frame. The conveying mechanism is used to transport molds. The grinding mechanism is used to grind the molds on the conveying mechanism. The unloading end of the frame is provided with a reversing module and a second conveying component. The reversing module is connected to the second conveying component, and the included angle between the second conveying component and the frame is 90°. The reversing module is used to send the mold located at the unloading end of the frame to the second conveying component. The reversing module includes a lifting component and a conveying mechanism. The lifting component is used to lift the mold located at the unloading end of the frame to the same height as the second conveying component. The conveying mechanism is used to convey the lifted mold to the second conveying component.

[0008] By adopting the above technical solution, the grinding of the mold is achieved through the cooperation of the conveying mechanism and the grinding mechanism. After grinding, the mold is transported to the unloading end of the frame by the conveying mechanism. When the mold reaches the unloading end, the lifting component lifts the mold until it is at the same height as the second conveying component. Then, the conveying mechanism transfers the mold lifted by the lifting component to the second conveying component. Since the angle between the second conveying component and the frame is 90°, the purpose of transporting the mold in a 90° direction is achieved, so as to facilitate the delivery of the mold to the next processing equipment. This plays a positive guiding role in improving the convenience of transporting the ground mold.

[0009] Preferably, the lifting assembly includes a first driving member and a support plate. The first driving member is disposed on the frame, the support plate slides with the frame, and the conveying mechanism is disposed on the support plate. The first driving member is used to drive the support plate to carry the conveying mechanism to move vertically up and down along the frame.

[0010] By adopting the above technical solution, the bearing plate and the frame slide together, which improves the stability of the first driving component driving the bearing plate to carry the conveying mechanism to move in the vertical direction of the frame, and reduces the sway of the bearing plate when it moves in the vertical direction.

[0011] Preferably, the lifting assembly further includes four guide rods, which are arranged in a rectangular array and fixedly connected to the bearing plate, and the four guide rods slide in cooperation with the frame.

[0012] By adopting the above technical solution, the four guide rods slide in coordination with the frame, thus limiting the movement path of the bearing plate along the vertical direction of the frame. This reduces the probability of the bearing plate swaying during its movement along the vertical direction of the frame due to uneven weight distribution of the conveying mechanism on which the mold is placed, causing the mold to shift or fall off.

[0013] Preferably, the conveying mechanism includes a second driving member, a carrier frame, and a conveying assembly. The carrier frame is disposed on the carrier plate, and the spatial relationship between the carrier frame and the frame is perpendicular. The carrier frame faces the second conveying assembly. The second driving member is disposed on the carrier frame, and the conveying assembly is rotatably connected to the carrier frame. The second driving member is used to drive the conveying assembly to rotate along the carrier frame.

[0014] By adopting the above technical solution, since the support frame faces the second conveying component, the path of the second drive component driving the conveying component to transport the mold to the second conveying component is limited. This reduces the probability that the mold cannot accurately reach the second conveying component due to the deviation of the transmission path between the second conveying component and the conveying component. The second drive component drives the conveying component to rotate along the support frame, providing power for the mold to be transported to the second conveying component, without the need for operators to handle the mold.

[0015] Preferably, the support frame is provided with an end baffle, which is used to limit the maximum distance the mold is conveyed along the conveying mechanism.

[0016] By adopting the above technical solution, the end baffle limits the maximum distance that the molds conveyed by the conveying mechanism on the frame can move along the frame, thereby reducing the probability that the molds cannot accurately reach the conveying components due to excessive distances along the frame.

[0017] Preferably, an auxiliary conveying and guiding assembly is provided on the frame located between the grinding mechanism and the support frame. The auxiliary conveying and guiding assembly includes a first driving cylinder and a guide wheel. The first driving cylinder is disposed on the frame, and the piston rod of the first driving cylinder faces the mold. The guide wheel is rotatably connected to the end of the piston rod of the first driving cylinder. When the conveying mechanism moves along the frame, the piston rod of the first driving cylinder carries the guide wheel to move toward the surface of the mold until the guide wheel abuts against the surface of the mold.

[0018] By adopting the above technical solution, the first drive cylinder and the guide wheel cooperate to provide rolling friction force to the mold located on the frame and transported by the conveying mechanism, thereby reducing the resistance borne by the conveying mechanism when transporting the mold and facilitating the smooth arrival of the mold at the conveying component.

[0019] Preferably, the second conveying component is provided with a guide groove along its length, and the groove width of the guide groove and the mold width are in a clearance fit.

[0020] By adopting the above technical solution, since the guide groove width and the mold width tolerance are in clearance fit, the mold transportation path along the conveying component to the second conveying component is limited, reducing the probability of the mold shifting or falling off due to mechanical vibration between components, either along the second conveying component or during the process of moving the mold to the second conveying component through the conveying component.

[0021] Preferably, the frame has guide holes arranged in a rectangular array, the same number as the number of guide rods, and guide copper sleeves are provided in the guide holes, with the guide rods slidingly engaging with the guide copper sleeves.

[0022] By adopting the above technical solution, the guide copper sleeve helps to reduce the frictional force when the guide rod slides along the frame, and reduces the probability of irreversible mechanical wear on the guide rod and / or the frame as the number of times the guide rod slides along the frame increases, causing the fit between the guide rod and the frame to loosen, thus resulting in a deterioration in the guiding effect.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When the mold reaches the unloading end, the mold is lifted by the lifting component until it is at the same height as the second conveying component. Then, the mold after being lifted by the lifting component is conveyed to the second conveying component by the conveying mechanism. Since the angle between the second conveying component and the frame is 90°, the purpose of transporting the mold in a 90° direction is achieved.

[0025] 2. By using end baffles, the molds conveyed by the conveying mechanism on the frame are limited to a certain distance along the frame, reducing the probability that the molds cannot accurately reach the conveying components due to excessive conveying distance along the frame.

[0026] 3. Through the cooperation of the first drive cylinder and the guide wheel, rolling friction is provided to the mold located on the frame and transported by the conveying mechanism, reducing the resistance encountered by the conveying mechanism when transporting the mold, and facilitating the smooth arrival of the mold at the conveying component.

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] This application discloses a mold grinding device with a reversing function. (Refer to...) Figure 1 and Figure 2 A mold grinding device with reversing function includes a frame 1 and a grinding mechanism 2 and a conveying mechanism 3 disposed on the frame 1. One end of the frame 1 is a loading end 4 and the other end is a unloading end 41. The grinding mechanism 2 is disposed between the loading end 4 and the unloading end 41 of the frame 1. The conveying mechanism 3 is used to transport the mold. The grinding mechanism 2 is used to grind the mold on the conveying mechanism 3. The unloading end 41 of the frame 1 is provided with a reversing module 5 and a second conveying component 6. The reversing module 5 is connected to the second conveying component 6, and the included angle formed between the second conveying component 6 and the frame 1 is 90°. The reversing module 5 is used to send the mold located at the unloading end 41 of the frame 1 to the second conveying component 6. The reversing module 5 includes a lifting component 51 and a conveying mechanism 52. The lifting component 51 is used to lift the mold located at the unloading end 41 of the frame 1 to the same height as the second conveying component 6. The conveying mechanism 52 is used to convey the lifted mold to the second conveying component 6.

[0035] The “conveying mechanism 3” and “grinding mechanism 2” are existing grinding equipment, and their specific composition and working principle will not be described in detail here.

[0036] Furthermore, refer to Figure 3 and Figure 4The lifting assembly 51 includes a first driving member and a support plate 512. The first driving member is mounted on the frame 1, and the support plate 512 slides and cooperates with the frame 1. The conveying mechanism 52 is mounted on the support plate 512. The first driving member is used to drive the support plate 512 to carry the conveying mechanism 52 to move vertically along the frame 1.

[0037] The first driving component can be a motor screw drive module. In this embodiment, in conjunction with the mold to be processed, the first driving component is preferably a second driving cylinder 511. The second driving cylinder 511 is installed at the unloading end 41 of the frame 1, and the piston rod of the second driving cylinder 511 moves upward in the vertical direction. At the same time, the piston rod of the second driving cylinder 511 is fixedly connected to the bearing plate 512. By controlling the extension and retraction of the piston rod of the second driving cylinder 511, the bearing plate 512 can be driven to move synchronously along the frame 1 with the piston rod of the second driving cylinder 511.

[0038] Correspondingly, the lifting assembly 51 also includes four guide rods 513, which are arranged in a rectangular array and fixedly connected to the support plate 512. The four guide rods 513 slide in cooperation with the frame 1. The frame 1 has guide holes 10, the same number as the guide rods 513, along the rectangular array. Guide copper sleeves 101 are installed in the guide holes 10, and the guide rods 513 slide in cooperation with the guide copper sleeves 101.

[0039] Because the four guide rods 513 slide and cooperate with the frame 1, the movement path of the bearing plate 512 along the vertical direction of the frame 1 is limited by the four guide rods 513. This reduces the probability that the bearing plate 512 will wobble during its movement along the vertical direction of the frame 1 due to uneven weight distribution of the conveyor mechanism 52 on which the mold is placed, causing the mold to shift or fall off.

[0040] The guide copper sleeve 101, with its soft and wear-resistant properties, helps reduce the frictional force when the guide rod 513 slides along the frame 1. This reduces the probability of irreversible mechanical wear on the guide rod 513 and / or the frame 1 due to increased sliding frequency, which could lead to loosening of the fit between the guide rod 513 and the frame 1 and consequently, a deterioration in the guiding effect. When the guide copper sleeve 101 becomes worn, it can be easily replaced, making the operation simple and highly stable.

[0041] Refer to Figure 3 and Figure 4The conveying mechanism 52 includes a second driving member, a support frame 522, and a conveying assembly 523. The support frame 522 is disposed on the support plate 512. The support frame 522 and the frame 1 are arranged perpendicularly to each other, and the support frame 522 faces the second conveying assembly 6. The second driving member is disposed on the support frame 522. The conveying assembly 523 is rotatably connected to the support frame 522. The second driving member is used to drive the conveying assembly 523 to rotate along the support frame 522.

[0042] Specifically, the conveying assembly 523 includes a first conveyor belt 5231, a second conveyor belt 5232, and a synchronous gear set (not shown in the figure). The synchronous gear set contains four gears, with two gears forming a group. The two groups of gears rotate symmetrically about the centerline of the support frame 522 along the width direction and are supported on the support frame 522. The two gears in each group are located at the two ends of the support frame 522 along the length direction. When the four gears rotate and are supported on the support frame 522, the gears protrude from the surface of the support frame 522, that is, the plane where the tooth crest of the gear is located is higher than the plane where the support frame 522 is located. The first conveyor belt 5231 and the second conveyor belt 5232 are respectively fitted onto the two groups of gears.

[0043] Furthermore, the conveying assembly 523 also includes a drive shaft 5233, which runs through the side wall of the support frame 522 and is rotatably supported on the support frame 522. Two gears located on the same side of the support frame 522 are coaxially fixed with the drive shaft 5233.

[0044] Correspondingly, the second driving component can be a synchronous motor. In this embodiment, in order to improve the stability of mold conveying, the second driving component is preferably a servo motor 521. The servo motor 521 is mounted on the support plate 512, and the output shaft of the servo motor 521 is coaxially fixed with the drive shaft 5233.

[0045] Therefore, when the output shaft of the servo motor 521 moves, the drive shaft 5233, which is coaxially fixed with the output shaft of the servo motor 521, will rotate synchronously along the support frame 522 following the output shaft of the servo motor 521. Through the transmission of the synchronous gear set, it will drive the first conveyor belt 5231 and the second conveyor belt 5232 to rotate synchronously along the support frame 522.

[0046] Since the plane where the tooth crest of the gear is located is higher than the plane where the support frame 522 is located, when the first conveyor belt 5231 and the second conveyor belt 5232 are installed on the synchronous gear set, the horizontal plane where the first conveyor belt 5231 and the second conveyor belt 5232 are located is higher than the height of the support frame 522.

[0047] Therefore, since the support frame 522 faces the second conveying assembly 6, the path for the first conveyor belt 5231 and the second conveyor belt 5232 to transport the mold to the second conveying assembly 6 is defined. This reduces the probability that the mold will not accurately reach the second conveying assembly 6 due to deviations in the transport path between the second conveying assembly 6 and the first conveyor belt 5231 and the second conveyor belt 5232. The first conveyor belt 5231 and the second conveyor belt 5232 are driven to rotate along the support frame 522 by the servo motor 521, providing power for the mold to be transported to the second conveying assembly 6, without the need for operators to handle the mold.

[0048] In addition, an end baffle 7 is provided on the support frame 522. The end baffle 7 is used to limit the maximum distance that the mold can be conveyed along the conveying mechanism 3. The end baffle 7 is located on the side of the support frame 522 near the servo motor 521, and the end baffle 7 is arranged in the same direction as the first conveyor belt 5231 and the second conveyor belt 5232. The end baffle 7 limits the maximum distance that the mold conveyed by the conveying mechanism 3 on the frame 1 can move along the frame 1, reducing the probability that the mold cannot accurately reach the conveying component 523 due to the excessive distance that the mold can be conveyed along the frame 1.

[0049] Reference Figure 3 and Figure 5 An auxiliary guide assembly is provided on the frame 1 located between the grinding mechanism 2 and the support frame 522. The auxiliary guide assembly includes a first drive cylinder 81 and a guide wheel 82. The first drive cylinder 81 is located on the frame 1, and the piston rod of the first drive cylinder 81 faces the mold. The guide wheel 82 is rotatably connected to the end of the piston rod of the first drive cylinder 81. When the conveying mechanism 3 moves along the frame 1, the piston rod of the first drive cylinder 81 carries the guide wheel 82 to move towards the mold surface until the guide wheel 82 abuts against the mold surface.

[0050] Its function is to provide rolling friction force to the mold located on the frame 1 and transported by the conveying mechanism 3 through the cooperation of the first drive cylinder 81 and the guide wheel 82, thereby reducing the resistance borne by the conveying mechanism 3 when transporting the mold and facilitating the smooth arrival of the mold at the conveying component 523.

[0051] Reference Figures 1-3 The second conveying component 6 includes a conveying frame 61 and a conveying module 62. The angle between the conveying frame 61 and the frame 1 is 90°. The conveying module 62 is installed on the conveying frame 61. The conveying module 62 is a conventional product conveying component in existing industrial production. Its specific composition and working principle will not be described in detail here.

[0052] The second conveying component 6 is provided with a guide groove 9 in the opposite direction along its length. The width of the guide groove 9 is in clearance fit with the width of the mold. The guide groove 9 is formed by two partition plates 11, which are located on both sides of the conveying frame 61 along its width.

[0053] Therefore, since the guide groove 9 and the mold width are in a clearance fit, the mold transport path along the conveying assembly 523 to the conveying module 62 is limited, reducing the probability of the mold shifting or falling off due to mechanical vibration between components, which may occur during the process of moving the mold to the conveying module 62 or through the conveying assembly 523.

[0054] The implementation principle of a mold grinding device with reversing function in this application embodiment is as follows: the grinding process of the mold is realized by the cooperation of the conveying mechanism 3 and the grinding mechanism 2. After grinding, the mold is transported to the unloading end 41 of the frame 1 by the conveying mechanism 3. When the mold reaches the unloading end 41, the mold is lifted by the lifting component 51 until it is at the same height as the second conveying component 6. Then, the mold lifted by the lifting component 51 is conveyed to the second conveying component 6 by the conveying mechanism 52. Since the included angle between the second conveying component 6 and the frame 1 is 90°, the purpose of reversing the mold by 90° is realized, so as to facilitate the delivery of the mold to the next processing equipment and play a positive guiding role in improving the convenience of transporting the ground mold.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
