Description

Technical Field

[0001] This invention relates to the field of mold forming technology, specifically to an automatic bolt locking mechanism and an automated mold closing device. Background Technology

[0002] Cement mortar strength testing is a mandatory indicator for cement companies before cement products leave the factory. Cement companies must test the flexural and compressive strength of cement according to the national standard GB / T17671. The test results directly determine the cement grade, therefore, the strength of the cement mortar needs to be tested. Strength testing requires cement mortar test blocks, which are made using a three-part mold. After use, the existing mold needs to be manually disassembled to remove the cement mortar test blocks for testing. The mold then needs to be reassembled. During reassembly, the bolts of the upper and lower molds need to be tightened manually. However, manual operation often results in insufficient tightening, and vibrations during mold forming can cause loosening, leading to poor mold formation, leakage, and the need to redo the process, resulting in high costs. Summary of the Invention

[0003] On the one hand, the present invention provides an automatic locking mechanism for fastening bolts to solve the problems of unreliability of existing manual locking methods, easy loosening after vibration, and affecting the molding effect.

[0004] On the other hand, the present invention also provides an automated mold closing device to solve the problems of cumbersome and inefficient existing mold closing processes.

[0005] On one hand, the present invention provides an automatic locking mechanism for fastening bolts, comprising: A drive assembly has a drive shaft with a mounting groove at the end of the drive shaft away from the drive assembly. The elastic element is located in the mounting groove; The floating bit is connected to the elastic element via a sleeve, and the other end of the floating bit is adapted to abut against the fastening bolt.

[0006] Beneficial effects: The automatic bolt locking mechanism provided by this invention allows for easy tightening of bolts. Simply align the floating bit with the bolt, and the drive assembly applies a tightening force to the floating bit via the transmission shaft and elastic element. No manual operation is required, ensuring a secure tightening effect. Furthermore, the elastic element allows the floating bit to remain floating, preventing jamming or jamming during bolt engagement and tightening, ensuring smooth bolt tightening. Simultaneously, the elastic element compresses and stores energy when the floating bit applies tightening force to the bolt. After tightening, a slight reverse rotation of the floating bit allows it to separate from the bolt under the elastic potential energy of the elastic element, making operation more convenient.

[0007] In one alternative embodiment, the groove of the mounting slot is provided with a flared opening, and the end of the sleeve near the elastic element is provided with an outward protrusion, which is inserted into the flared opening to connect the floating bit and the elastic element.

[0008] Because the contact area between the floating bit and the elastic element is small, and the elastic element is prone to deformation under stress, direct connection between the two may lead to unreliable connection. Therefore, a sleeve is provided outside the floating bit, and the outer protrusion on the sleeve is inserted into the flared opening of the mounting groove to achieve a reliable connection between the floating bit and the elastic element, preventing the two from shifting under stress, causing connection failure, and thus affecting the tightening effect on the fastening bolt.

[0009] In one alternative implementation, the drive assembly includes a servo motor and a speed reducer connected together, with the output shaft of the speed reducer connected to a drive shaft via a coupling.

[0010] The servo motor provides the tightening force for the floating bit to fasten the bolts, and the force applied can be precisely controlled. The reducer ensures that the tightening force applied by the servo motor is stable and reliable, and the coupling ensures the reliability of the connection between the reducer output shaft and the drive shaft.

[0011] On the other hand, the present invention also provides an automated mold closing device, including an automatic locking mechanism for fastening bolts.

[0012] Beneficial effects: The automated mold closing equipment provided by this invention, when the mold is closed, the automatic locking mechanism of the fastening bolts locks the upper mold and the lower mold to complete the mold closing. The whole process does not require manual operation, realizes smooth mold closing, avoids the deformation of the mold caused by collisions due to manual operation, improves mold closing efficiency, and reduces labor costs.

[0013] In one optional embodiment, the upper mold closing mechanism is further included. The upper mold closing mechanism includes a mold closing support plate and a horizontal plate stop block and a vertical plate stop block disposed on the mold closing support plate, as well as a vertical plate pressing assembly disposed below the mold closing support plate. The mold closing support plate is provided with a plurality of through holes, and the vertical plate pressing assembly passes through the through holes to press the vertical plate and the vertical plate stop block together.

[0014] The horizontal and vertical baffles can initially fix the positions of the horizontal and vertical plates. Since there are relatively many vertical plates, in addition to the vertical plates on the outside, there will also be vertical plates in the middle. Therefore, a vertical plate clamping component is added. The vertical plate clamping component and the vertical plate baffle cooperate to fix the vertical plate in the middle, which further improves the accurate definition of the position of the vertical plate and ensures that the horizontal and vertical plates can be smoothly engaged with the mold.

[0015] In one optional embodiment, the vertical plate clamping assembly includes a vertical plate clamping cylinder, a column base plate connected to the vertical plate clamping cylinder, a slide rail on the column base plate, and a plurality of clamping columns. The slide rail is slidably connected to the lower surface of the mold closing support plate. When the vertical plate is placed on the mold closing support plate, the vertical plate clamping cylinder is adapted to drive the column base plate to move until the plurality of clamping columns are aligned with the through holes on the mold closing support plate, and apply clamping force to the vertical plate through the through holes.

[0016] The slide rail guides the movement of the column base plate. When no vertical plate is placed on the mold closing support plate, the clamping column is located below the mold closing support plate to facilitate the placement of the vertical plate. After the vertical plate is placed in the predetermined position, multiple clamping columns are set one-to-one with the through holes on the mold closing support plate. The clamping columns pass through the through holes and together with the vertical plate baffle fix the position of the vertical plate.

[0017] In one optional embodiment, the upper and lower mold closing mechanism is further included. The upper and lower mold closing mechanism includes a first linear module, a transfer platform slidably disposed on the first linear module, and a first upper mold clamping assembly and a second upper mold clamping assembly disposed opposite to each other on both sides of the transfer platform. An automatic locking mechanism for fastening bolts is disposed between the first upper mold clamping assembly and the second upper mold clamping assembly.

[0018] The first upper mold clamping assembly and the second upper mold clamping assembly apply clamping force to the upper mold from two opposite directions simultaneously to prevent it from moving after being subjected to the locking force applied by the automatic locking mechanism of the fastening bolts, which would affect the mold closing effect of the upper and lower molds.

[0019] In one optional embodiment, the system further includes a multi-axis manipulator, which includes a second linear module and a third linear module slidably connected to the second linear module. The third linear module is equipped with a manipulator. The movement directions of the second linear module, the third linear module, and the manipulator are perpendicular to each other. The manipulator is equipped with a horizontal and vertical plate clamping structure, a lower mold clamping structure, and an upper mold suction structure.

[0020] Multi-axis robotic arms can simultaneously grip and transfer the upper mold horizontal plate, vertical plate, lower mold, and the upper mold after mold closing. They have a high degree of integration, and the upper mold suction structure ensures that the shape and position of the upper mold remain unchanged after transfer, thus avoiding affecting the mold closing effect.

[0021] In one optional embodiment, the horizontal and vertical plate clamping structure includes a first guide rod electric cylinder and an electric swing table, a first gripper cylinder, and a first gripper connected in sequence to the first guide rod electric cylinder. The electric swing table is adapted to adjust the clamping direction when the first gripper clamps the horizontal or vertical plate. The lower mold clamping structure includes a second guide rod electric cylinder and a second gripper cylinder and a second gripper connected in sequence to the second guide rod electric cylinder. The upper mold suction structure includes a third guide rod electric cylinder and an electromagnet connected to the third guide rod electric cylinder.

[0022] The electric swing table allows for simultaneous gripping of horizontal or vertical plates with only one set of first grippers, further reducing costs. The second gripper is used to grip the lower template, and the electromagnet is used to pick up the upper template. Each part works independently without interfering with the others, and is integrated into one unit, resulting in a smaller overall size.

[0023] In one optional embodiment, the system further includes an oiling mechanism, which comprises a facade oiling assembly, a bottom surface oiling assembly, and an inner panel atomizing spraying assembly.

[0024] The vertical surface oiling component is used to evenly apply oil to the vertical surfaces of the horizontal plates, vertical plates, and lower mold. The bottom surface oiling component is used to evenly apply oil to the bottom surfaces of the horizontal plates, vertical plates, and lower mold. The inner side atomizing oil spraying component is used to evenly apply oil to the contact surfaces inside the mold after molding, avoiding the unevenness of manual oiling and reducing the difficulty of demolding the mold.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] The following is combined with Figures 1 to 16 Embodiments of the present invention are described.

[0030] In this embodiment, the trial mold 1 is as follows: Figure 1 and Figure 2 As shown, the upper mold 101 and the lower mold 102 are included. The upper mold 101 includes a pair of horizontal plates 1011 facing each other and four vertical plates 1012 between the pair of horizontal plates 1011. Four slots are provided on the horizontal plates 1011 at intervals. The two ends of the vertical plates 1012 are inserted into the slots for fixation, and the upper mold 101 with three test block spaces is assembled. The cross-sectional area of ​​the lower mold 102 is slightly larger than that of the upper mold 101 to support the upper mold 101. It includes a lower template 1021 and fastening bolts 1022 on one side of the lower template 1021 and two positioning pins 1023 on the other side adjacent to the lower template 1021. The two positioning pins 1023 are fitted with one of the outer vertical plates 1012 to limit the position of the upper mold 101. Bolt holes are provided at the positions corresponding to the fastening bolts 1022 on the horizontal plates 1011. The other end of the fastening bolts 1022 is inserted into the bolt holes to fix the upper mold 101 and the lower mold 102.

[0031] According to an embodiment of the present invention, an automatic bolt locking mechanism 2 is provided, comprising: The drive assembly 201 has a drive shaft 202, and a mounting groove is provided at the end of the drive shaft away from the drive assembly 201. The elastic element 203 is disposed in the mounting groove; The floating bit 204 is connected to the elastic element 203 via the sleeve 205, and the other end of the floating bit 204 is adapted to abut against the fastening bolt.

[0032] refer to Figure 3 and Figure 4The floating bit 204, sleeve 205, elastic element 203, and drive shaft are coaxially arranged. The drive shaft includes a large end and a small end. The small end is connected to the drive assembly 201, and the large end is connected to the sleeve 205. The center of the large end has a mounting groove for the elastic element 203. The elastic element 203 can be a tension spring, with one end fixed to the bottom of the mounting groove and the other end abutting against the floating bit 204. When the automatic locking mechanism 2 for fastening bolts approaches the fastening bolt of the lower mold, the floating bit 204 continues to advance, aligning with the groove of the fastening bolt, to insert into or tighten the groove. At this time, the floating bit 204 presses the tension spring backward. Then, the drive assembly 201 drives the floating bit 204 to rotate. When the torque of the drive assembly 201 reaches a specified value, it stops rotating, completing the locking.

[0033] Beneficial effects: The automatic bolt locking mechanism provided by this invention allows for easy tightening of bolts. Simply align the floating bit 204 with the bolt, and the drive assembly 201 applies a tightening force to the floating bit 204 via the transmission shaft 202 and the elastic element 203. No manual operation is required, ensuring a secure tightening effect. Furthermore, the elastic element 203 keeps the floating bit 204 in a floating state, preventing jamming or jamming during bolt engagement and tightening, ensuring smooth bolt tightening. Simultaneously, the elastic element 203 compresses and stores energy when the floating bit 204 applies tightening force to the bolt. After tightening, a slight reverse rotation of the floating bit 204 allows it to separate from the bolt under the elastic potential energy of the elastic element 203, making operation more convenient.

[0034] In one embodiment, the groove of the mounting slot is provided with a flared opening, and the sleeve 205 is provided with an outward protrusion at one end near the elastic member 203. The outward protrusion is inserted into the flared opening to connect the floating bit 204 and the elastic member 203.

[0035] refer to Figure 4 The groove of the mounting slot expands radially outward to form a flared opening. The inner diameter of the flared opening is larger than the diameter of the elastic element 203. Thus, when the sleeve 205 is aligned with the drive shaft 202, the outward protrusion inserts into the flared opening, providing a certain degree of constraint to the elastic element 203. The outward protrusion is integrally formed with the sleeve 205, and its diameter is smaller than the diameter of the sleeve 205. Of course, the sleeve 205 and the drive shaft 202 can also be connected by a threaded connection; no specific restrictions are placed here.

[0036] Because the contact area between the floating bit 204 and the elastic element 203 is small, and the elastic element 203 is prone to deformation under force, direct connection between the two may lead to unreliable connection. Therefore, a sleeve 205 is provided outside the floating bit 204, and the floating bit 204 and the elastic element 203 are reliably connected by inserting the protrusion on the sleeve 205 into the flared opening of the mounting groove. This prevents the two from shifting under force, causing connection failure, and thus affecting the tightening effect on the fastening bolt.

[0037] In one embodiment, the drive assembly 201 includes a servo motor 2011 and a reducer 2012 connected together, and the output shaft of the reducer 2012 is connected to the drive shaft 202 via a coupling 206.

[0038] refer to Figure 3 and Figure 4 The servo motor 2011 is axially perpendicular to the drive shaft 202. The reducer 2012 is L-shaped to convert the driving force provided by the servo motor 2011 from the vertical direction to the horizontal direction. The reducer 2012 is connected to the coupling 206 through the motor mounting plate 207, and the drive shaft 202 is mounted in the motor mounting plate 207 through the bearing seat 208.

[0039] The servo motor 2011 provides the tightening force for the floating bit 204 to fasten the bolts, and the force can be precisely controlled. The reducer 2012 ensures that the tightening force applied by the servo motor 2011 is stable and reliable. The coupling 206 ensures the reliability of the connection between the output shaft of the reducer 2012 and the transmission shaft 202.

[0040] On the other hand, the present invention also provides an automated mold closing device, including an automatic locking mechanism 2 for fastening bolts, a trial mold placement platform 3, an oiling mechanism 4, an upper mold closing mechanism 5, an upper and lower mold closing mechanism 6, and a multi-axis robot 7. The multi-axis robot 7 is adapted to transport the horizontal plate and the vertical plate on the trial mold placement platform 3 to the oiling mechanism 4 for oiling, and then to the upper mold closing mechanism 5 to complete the upper mold closing. After that, it is locked with the lower mold placed in the upper and lower mold closing mechanism 6 by the automatic locking mechanism 2 for fastening bolts to complete the mold closing.

[0041] refer to Figure 5 and Figure 6The automated mold-closing equipment also includes a frame 8 that provides a stable operating platform for each mechanism. The automatic bolt tightening mechanism 2, oiling mechanism 4, upper mold-closing mechanism 5, upper and lower mold-closing mechanism 6, and multi-axis robot 7 are all housed within the frame 8. The frame 8 is L-shaped, and the trial mold placement platform 3 is located at the notch of the L-shape. The frame 8 includes an upper frame 801, a lower frame 802, and a large plate 803 connecting the upper and lower frames. The upper frame 801 serves as the outer frame of the entire structure, the large plate 803 serves as the support surface for each mechanism, and the lower frame 802 supports the entire machine platform. Adjustable leveling feet at the bottom ensure that the large plate 803 is level, guaranteeing the stable operation of all mechanisms.

[0042] refer to Figure 16 The trial mold placement table 3 includes a trial mold placement machine 301 and a horizontal plate placement area 302, a vertical plate placement area 303, and a lower mold placement area 304 provided on the trial mold placement machine 301. The robot arm 703 places the disassembled trial mold parts on the trial mold placement table 3 according to the specified positions. After cleaning, the robot arm 703 picks up the corresponding trial mold parts and places them in the corresponding positions for mold closing.

[0043] Beneficial effects: The automated mold closing equipment provided by this invention, when closing the mold, the multi-axis robot 7 respectively grips the horizontal and vertical plates of the upper mold on the test mold placement platform 3, applies oil, and places them in the upper mold closing mechanism 5 for upper mold closing. The lower mold is placed by the multi-axis robot 7 into the upper and lower mold closing mechanism 6 for positioning and clamping. Then, after the multi-axis robot 7 places the upper mold into the lower mold, the automatic locking mechanism 2 of the fastening bolts locks the two together to complete the mold closing. The whole process does not require manual operation, realizes smooth mold closing, avoids the deformation of the mold caused by collisions due to manual operation, improves mold closing efficiency, and reduces labor costs.

[0044] In one embodiment, the upper mold closing mechanism 5 includes a mold closing support plate 501, a horizontal plate stop 502 and a vertical plate stop 503 disposed on the mold closing support plate 501, and a vertical plate pressing assembly 504 disposed below the mold closing support plate 501. The mold closing support plate 501 is provided with a plurality of through holes, and the vertical plate pressing assembly 504 passes through the through holes to press the vertical plate and the vertical plate stop 503 together.

[0045] refer to Figure 7 and Figure 8The upper mold closing mechanism 5 also includes a first base plate 505 and a plurality of first columns 506 disposed on the first base plate 505. A mold closing support plate 501 is disposed at the top of the first columns 506. A pair of third gripper cylinders 507 are also disposed on the first base plate 505. The third gripper cylinders 507 are connected to third grippers 509 through a connecting plate 508. The third grippers 509 are connected to the horizontal plate stop 502 to apply an inward clamping force to the horizontal plate. The horizontal plate stop includes a first horizontal plate stop disposed on the outside of the horizontal plate and a second horizontal plate stop disposed at the connection between the horizontal plate and the vertical plate. The number of first horizontal plate stops can be one, two or more depending on the length of the horizontal plate. A second horizontal plate stop is provided at the connection between each horizontal plate and the vertical plate to limit and guide the connection position and prevent the two from shifting when connected. The vertical plate stop 503 is located on one side of the vertical plate placement position. One or more can be set according to the length of the vertical plate. The position of the through hole corresponds to the position of the vertical plate stop 503 and is located on both sides of the same vertical plate to apply opposing forces to the vertical plate to keep it vertical and facilitate mold closing with the horizontal plate.

[0046] The horizontal plate stop 502 and the vertical plate stop can initially fix the position of the horizontal plate and the vertical plate. Since there are relatively many vertical plates, in addition to the vertical plates on the outside, there will also be vertical plates in the middle. Therefore, a vertical plate clamping component 504 is added. The vertical plate clamping component 504 and the vertical plate stop 503 cooperate to fix the vertical plate in the middle, which further improves the accurate definition of the position of the vertical plate and ensures that the horizontal plate and the vertical plate can smoothly engage the mold.

[0047] In one embodiment, the vertical plate clamping assembly 504 includes a vertical plate clamping cylinder 5041, a column base plate 5042 connected to the vertical plate clamping cylinder 5041, a slide rail 5043 disposed on the column base plate 5042, and a plurality of clamping columns 5044. The slide rail 5043 is slidably connected to the lower surface of the mold closing support plate 501. When the vertical plate is placed on the mold closing support plate 501, the vertical plate clamping cylinder 5041 is adapted to drive the column base plate 5042 to move until the plurality of clamping columns 5044 are aligned with the through holes on the mold closing support plate 501, and apply clamping force to the vertical plate through the through holes.

[0048] refer to Figure 9The vertical plate clamping assembly 504 is arranged parallel to the vertical plate arrangement direction. An end clamping plate 5045 is also provided at the end of the column base plate 5042 away from the vertical plate clamping cylinder 5041. An end clamping block 5046 is provided on the end clamping plate 5045, corresponding to one of the outer vertical plates. A vertical plate stop 503 is provided on the outer side of the opposite vertical plate. The thickness of this stop 503 is greater than that of the middle stop 503. This is because the end clamping block 5046 exerts an inward force on the vertical plate under the action of the vertical plate clamping cylinder 5041. This force is relatively large, so the opposite vertical plate stop 503 needs to be thicker to ensure balanced force distribution. Multiple clamping columns 5044 are symmetrically distributed on both sides of the slide rail 5043. After the horizontal and vertical plates are placed in the predetermined positions of the mold clamping support plate 501, the vertical plate clamping cylinder 5041 drives the clamping column 5044 to move backward. The clamping column 5044 passes through the through hole on the mold clamping support plate 501 to clamp the vertical plate. A pair of third gripper cylinders 507 drive the third gripper 509 to clamp the horizontal plates on both sides, clamping the horizontal plate slots with the ends of the vertical plates.

[0049] The slide rail 5043 guides the movement of the column base plate 5042. When no vertical plate is placed on the mold closing support plate 501, the clamping column 5044 is located below the mold closing support plate 501 to facilitate the placement of the vertical plate. After the vertical plate is placed in the predetermined position, multiple clamping columns 5044 are set one-to-one with the through holes on the mold closing support plate 501. The clamping columns 5044 pass through the through holes and together with the vertical plate baffle fix the position of the vertical plate.

[0050] In one embodiment, the upper and lower mold closing mechanism 6 includes a first linear module 601, a transfer platform 602 slidably disposed on the first linear module 601, and a first upper mold clamping assembly 603 and a second upper mold clamping assembly 604 disposed opposite to each other on both sides of the transfer platform 602. The fastening bolt automatic locking mechanism 2 is disposed between the first upper mold clamping assembly 603 and the second upper mold clamping assembly 604.

[0051] refer to Figure 10The first linear module 601 is mounted on the second base plate 605. The second base plate 605 has a rear end stop 606 at its end to prevent the transfer platform 602 from sliding out of the first linear module 601. The transfer platform 602 is used to place the upper and lower molds. A mold positioning block 607 is provided on the opposite edge of the transfer platform 602, opposite to the automatic locking mechanism 2 for fastening bolts. The upper and lower mold closing mechanism 6 also includes a set of lower mold clamping assemblies arranged opposite each other. The first upper mold clamping assembly 603 includes a slide cylinder 6031, an end push plate 6032 mounted on the slide cylinder 6031, and a cylinder support frame 6033 for supporting the slide cylinder 6031. The end push plate 6032 is correspondingly arranged with the outer vertical plate. The second upper mold clamping assembly 604 is the first clamping cylinder located on the opposite side. A second clamping cylinder 608 for clamping the upper mold is also provided on one side of the automatic locking mechanism 2 for fastening bolts.

[0052] After the robotic arm 703 picks up the lower mold and places it on the transfer platform 602, a set of lower mold clamping components rotates 90° at the end and clamps the lower mold. The robotic arm 703 picks up the upper mold and places it above the lower mold. The slide cylinder 6031 drives the end push plate 6032 to press the upper mold vertical plate, and the end of the second clamping cylinder 608 rotates 90° to clamp the upper mold. When the photoelectric detection structure 609 detects that the upper and lower molds are in place, the fourth linear module 610 drives the automatic locking mechanism 2 of the fastening bolt to move to the fastening bolt of the lower mold through the moving platform 611. When the floating bit 204 is aligned with the fastening bolt, the servo motor 2011 drives the floating bit 204 to rotate and tighten the fastening bolt. When the torque of the servo motor 2011 reaches the specified data, it stops rotating, and the whole thing is moved backward by the fourth linear module 610, completing the mold closing. The first linear module 601 moves the transfer platform 602 and the test mold to the end, where they are picked up by the robot arm 703 and placed on the buffer machine for easy use next time.

[0053] The first upper mold clamping assembly 603 and the second upper mold clamping assembly 604 apply clamping force to the upper mold from two opposite directions simultaneously to prevent it from moving after being subjected to the locking force applied by the automatic locking mechanism 2 of the fastening bolts, thus affecting the mold closing effect of the upper and lower molds.

[0054] In one embodiment, the multi-axis robot 7 includes a second linear module 701 and a third linear module 702 slidably connected to the second linear module 701. The third linear module 702 is provided with a robot 703. The movement directions of the second linear module 701, the third linear module 702 and the robot 703 are perpendicular to each other. The robot 703 is provided with a horizontal and vertical plate clamping structure 704, a lower mold clamping structure 705 and an upper mold suction structure 706.

[0055] refer to Figure 11The second linear module 701 is the Y-axis, the third linear module 702 is the X-axis, and the movement direction of the robot arm 703 is the Z-axis. The multi-axis robot arm 7 also includes a support column 707, on which an active support plate 708 is provided. The second linear module 701 is located on the active support plate 708. A follower support plate 709 is provided on one side of the second linear module 701. A follower slide rail 710 is provided on the follower support plate 709. A drag chain bracket 711 is provided on the follower slide rail 710. A drag chain 712 is provided on the drag chain bracket 711. An end stop is provided at the end of the follower slide rail 710. One end of the first X-axis support plate 713 is connected to the second linear module 701, and the other end is connected to the follower slide rail 710, forming a stable gantry frame structure. The first X-axis support plate 713 is provided with a second X-axis support plate 714, and the third linear module 702 is installed on the second X-axis support plate 714. The second linear module 701 drives the robot arm 703 to move in the Y-axis direction, and the third linear module 702 drives the robot arm 703 to move in the X-axis direction.

[0056] The multi-axis robot 7 can simultaneously grip and transfer the upper mold horizontal plate, vertical plate, lower mold, and the upper mold after mold closing. It has a high degree of integration, and the upper mold suction structure 706 ensures that the shape and position of the upper mold remain unchanged after transfer, thus avoiding affecting the mold closing effect.

[0057] In one embodiment, the horizontal and vertical plate clamping structure 704 includes a first guide rod electric cylinder 7041 and an electric swing table 7042, a first gripper cylinder 7043, and a first gripper 7044 connected in sequence to the first guide rod electric cylinder 7041. The electric swing table 7042 is adapted to adjust the clamping direction when the first gripper 7044 clamps the horizontal or vertical plate. The lower mold clamping structure 705 includes a second guide rod electric cylinder 7051 and a second gripper cylinder 7052 and a second gripper 7053 connected in sequence to the second guide rod electric cylinder 7051. The upper mold suction structure 706 includes a third guide rod electric cylinder 7061 and an electromagnet 7062 connected to the third guide rod electric cylinder 7061.

[0058] refer to Figure 12The horizontal and vertical plate clamping structure 704 also includes a rotating connector 7045 connected to both the electric swing table 7042 and the first gripper cylinder 7043. The rotating connector 7045 drives the first gripper cylinder 7043 and the first gripper 7044 to rotate synchronously with the electric swing table 7042, facilitating the clamping of the horizontal or vertical plate. The horizontal and vertical plate clamping structure 704 is connected to the lower mold clamping structure 705 via a first bracket 715. A back plate bracket 716 is provided on one side of the bracket, and a second guide rod electric cylinder 7051 is mounted on the back plate bracket 716. The lower mold clamping structure 705 is connected to the upper mold absorbing structure 706 via a second bracket 717. A base plate bracket 718 is provided on the second bracket 717, and a third guide rod electric cylinder 7061 is mounted on the base plate bracket 718. The third guide rod electric cylinder 7061 is connected to the electromagnet 7062 via an electromagnet support plate 7063.

[0059] When the robotic arm 703 moves to the mold placement platform 3, the first guide rod electric cylinder 7041 drives the first gripper cylinder 7043 to move downwards. The first gripper cylinder 7043 drives the first gripper 7044 to open, clamping the first mold horizontal plate and placing it on the oiling mechanism 4 for oiling. Then, it is placed on the predetermined position of the upper mold closing mechanism 5. Then, the second mold horizontal plate is clamped, oiled, and placed on the predetermined position of the upper mold closing mechanism 5. Next, the robotic arm 703 clamps the first mold vertical plate, rotates it electrically, and places it on the predetermined position of the upper mold closing mechanism 5. Then, the second, third, and fourth vertical plates are clamped and placed on the predetermined positions in sequence. Then, the second guide rod electric cylinder 7051 drives the second gripper cylinder 7052 to move downwards. The second gripper cylinder 7052 drives the second gripper 7053 to open and clamp the lower mold of the mold, lifting it to the transfer platform 602 of the upper and lower mold closing mechanism 6 and clamping it in place. At this point, the upper mold is closed, and the third guide rod electric cylinder 7061 drives the electromagnet 7062 to move downward until it contacts the upper mold and attracts the upper mold. The third guide rod electric cylinder 7061 moves upward to the oiling mechanism 4 to apply oil, and then moves to the top of the lower mold. The electromagnet 7062 disengages and the upper and lower molds are closed.

[0060] The electric swing table 7042 allows for the simultaneous gripping of horizontal or vertical plates with only one set of first grippers 7044, further reducing costs; the second gripper 7053 is used to grip the lower template, and the electromagnet 7062 is used to pick up the upper template. Each part works independently without interfering with each other, and is integrated into one unit, resulting in a small overall size.

[0061] In one embodiment, the oiling mechanism 4 includes a vertical oiling assembly 401, a bottom oiling assembly 402, and an inner panel atomizing spraying assembly 403.

[0062] refer to Figure 13The facade oiling assembly 401 includes a linear motor 4011 and a first oiling gun 4012 slidably mounted on the linear motor 4011. The first oiling gun 4012 has a first oiling nozzle 4013 at its top and a first oiling inlet 4014 at its bottom, which is connected to an oiling machine via an oil pipe. After the robotic arm 703 grips the horizontal or vertical plate or the lower mold, it suspends it above the first oiling nozzle 4013. The linear motor 4011 drives the first oiling gun 4012 to evenly apply oil to the facade of the horizontal or vertical plate.

[0063] refer to Figure 14 The bottom surface oiling assembly 402 includes an oiling gun holder 4021 and a second oiling gun 4022 disposed on the oiling gun holder 4021. The two opposite sides of the second oiling gun 4022 are a second oiling nozzle 4023 and a second oiling inlet 4024, respectively. After the robot arm 703 grips the upper mold or the lower mold, it suspends it at the second oiling nozzle 4023, and the second oiling nozzle 4023 sprays out machine oil to oil the bottom surface.

[0064] refer to Figure 15 The inner atomizing oil spraying assembly 403 includes a support 4031, a third base plate 4032 on top of the support 4031, and a fifth linear module 4033 on the third base plate 4032. A first photoelectric switch 4034 and a second photoelectric switch 4035 are sequentially arranged on one side of the fifth linear module 4033. An oiling nozzle bracket 4036 and an oiling nozzle 4037 are located at the second photoelectric switch 4035. The oiling nozzle 4037 is connected to an automatic oiling machine. When the test mold is placed at the first photoelectric switch 4034, the fifth linear module 4033 moves the test mold to the oiling nozzle 4037. After the second photoelectric switch 4035 detects the test mold, the three oiling nozzles 4037 simultaneously spray oil onto the three grooves of the test mold. After spraying, the oil is transported back to the first photoelectric switch 4034.

[0065] The vertical surface oiling component 401 is used to evenly apply oil to the vertical surfaces of the horizontal plate, vertical plate and lower mold. The bottom surface oiling component 402 is used to evenly apply oil to the bottom surfaces of the horizontal plate, vertical plate and lower mold. The inner side atomizing spraying component 403 is used to evenly apply oil to the contact surfaces inside the mold after molding. This avoids the unevenness of manual oiling and reduces the difficulty of demolding the mold.

[0066] The specific working process of the automated mold clamping equipment is as follows: First, the multi-axis robot 7 picks up the horizontal plate, vertical plate and lower mold from the mold placement table 3 and applies oil to the vertical oiling assembly 401 and the bottom oiling assembly 402. Then, the horizontal plate and vertical plate are placed at the predetermined positions of the upper mold closing mechanism 5, and the lower mold is placed on the transfer table 602 of the upper and lower mold closing mechanism 6 and fixed.

[0067] Then, a pair of third gripper cylinders 507 in the upper mold closing mechanism 5 move towards each other, applying clamping force to the horizontal plate, and fastening the groove of the horizontal plate and the protrusion of the vertical plate together, thus completing the mold closing of the upper mold.

[0068] Next, the multi-axis robot 7 uses an electromagnet 7062 to pick up the closed upper mold and place it on the lower mold of the transfer platform 602. The automatic bolt locking mechanism 2 tightens the bolts to lock the trial mold and completes the mold closing.

[0069] Finally, when using the test mold again, place the test mold on the inner side of the plate at the atomizing oil spraying assembly 403 to apply oil to the inner side of the test mold.
